Some of the things xLogic can do for you?

The xLogic Micro PLC provides solutions for commercial, industrial, building and domestic applications such as lighting, pumping, ventilation, shutter operations or in switching cabinets. The application field is widespread and these are just a few to mention. Using the RS485 bus and Ethernet connectivity allows the user to realize various extensive (real-time) monitoring and control applications.

Special versions without operator panel and display unit are available for series production applications in small machine, installation and cabinet building environments to further slash cost.

xLogic devices： xLogic Basic is available in two voltage classes:

*Classes 1:DC12-24V: i.e.: PR-6DC Series, PR-12DC series, PR-18 series, PR-24DC series.

*Classes2: AC110-240V: i.e.: PR-6AC Series, PR-12AC series, PR-18AC series , PR-24AC series.

In the versions:

* With Display: with “-HMI” model, such as PR-12DC-DA-R-HMI

* Without Display: PR-6 series and with “-CAP” model, such as PR-12DC-DA-R-CAP. Only PR-12 has -CAP version. PR-18,PR-24 all have display in default.

Expansion modules:

PR-E (applied to PR-18/PR-24 CPU)

* xLogic digital modules are available for operation with 12…24V DC, and 110.. .240 V AC, and are equipped with eight inputs and eight outputs.

* xLogic analog modules are available for operation with 12…24 V DC and are equipped with six digital and 4 analog inputs.

Communication cable and module:

l xLogic:RS232 communication cable (Model:ELC-RS232)

It is kind of universal cable with photoelectricity isolation which can be directly connected to standard 9-pin port of PC, also kind of interface module which can enable user’s program to be downloaded into xLogic CPU through xLogicsoft for running. It also is the connection cable between CPU and third party device with the RS232 port(just like HMI) in modbus communication system.

l xLogic: USB communication cable (Model: ELC-USB).

It is kind of communication cable with photoelectricity isolation through which PC with USB port only can be connected to xLogic main module, moreover, it has same features as ELC-RS232 module, so it is quite convenient for user whose computer has no standard serial port.

l xLogic: PRO-RS485 cable (Model: PRO-RS485).

It is kind of converter cable with photoelectricity isolation to make the program port serves as RS485 port.

l xLogic: RS485 module（Model：PR-RS485）

isolated 485 converter,used to bring out the terminals of RS485 port built-in PR-18,PR-24 series CPU for connection with third party devices.

Communication / Network

xLogic offers different ways to communicate within the system.

RS485 port

The RS485 port is used for communication between the CPU and various devices or equipments which have the standard RS485 port. Communicate using Modbus RTU/ASCII protocol.

Note：PR-RS485 module is required to connect the CPU to RS485 BUS.

RS232 or USB port (ELC-ES232/ ELC-USB needed)

If there is no network required and only one main module with some expansion modules is needed for the application, the down- and upload of the project to and from the main module happens over the standard RS232 or USB port. It allows system maintenance like monitoring too.

Note：PR-E-RS485 module is required to connect the CPU to RS485 BUS.

Ethernet network

If the application requires a system where more than one main module is needed and these main modules have to communicate, each Ethernet CPU will be connected directly to the Ethernet by the built-in LAN port. The project down- and upload to and from the main modules and the communication between the CPU happens over the Ethernet network. Furthermore the our free of charge SCADA can be also established connection with Ethernet CPU

Note xLogic CPU may be equipped with expansion modules of the different voltage class, but expansion module must be supplied the correct power corresponding to its type.

Each xLogic CPU provides the following connections for the creation of the circuit program, regardless of the number of connected blocks:

l Digital inputs I1 to I4(PR-6), I1 to I8(PR-12), I1 to IC（ELC-18），I1 to IE(PR-24). I11-I18(Expansion with address 1)...I161--I168(Expansion with address 16)

l Analog inputs I1 to I6(PR-18/PR-24), I1 to I4(PR-12), I11 to I14(PR-E expansion with address 1),....AI161 to AI164(PR-E expansion with address 16)

l Digital outputs Q1 to Q6（PR-18), Q1 to Q4(PR-12),Q1 to QA(PR-24);Q11 to Q18((PR-E expansion with address 1), Q161 to Q168(PR-E expansion with address 16)

l Digital flag blocks F1-F32(PR-6,PR-12-E), F1-F256(PR-12/PR-18/PR-24) ;

l -F8 : Startup flag

l -F64: Backlight control bit(to control the backlight of LCD and backlight of ELC-43TS)

l -F63: Buzzer of ELC-43TS control bit

l Analog flag blocks AF1 to AF256(PR-12/PR-18/PR-24);AF1-AF32(PR-6/PR-12-E)

Chapter 3 Installing/removing xLogic

Dimensions

The xLogic installation dimensions are compliant with DIN 43880.

xLogic can be snap-mounted to 35 mm DIN rails to EN 50022 or on the wall. xLogic width:

l EXM-E expansion module and PR-6 series CPU have a width of 48mm l PR-14,PR-18&ELC-12-N Series CPU has a width of 95mm.

l PR-E expansion modules have a width of 72mm.

l PR-24 Series CPU has a width of 133mm.

l PR-12 Series CPU has a width of 72mm

Note

The figure below shows you an example of the installation and removal of an PR-18 CPU and one expansion module of PR-18 CPU.

W a r n i n g

Always switch off power before you “remove” and “insert” an expansion module.

3.1 DIN rail mounting

Mounting

How to mount a xLogic module and an expansion module onto a DIN rail:

Hook the xLogic Basic module onto the rail.
Push down the lower end to snap it on. The mounting interlock at the rear must engage.
Hook the xLogic expansion module onto the rail
Slide the module towards the left until it touches the xLogic CPU.
Push down the lower end to snap it on. The mounting interlock at the rear must engage.
Remove the plastic cover in the expansion port of CPU and expansion module. 7. Plus the connector on the flat cable to CPU

Repeat the expansion module steps to mount further expansion modules.

Note:If you need install the expansion and CPU on different rows, you need order the longer flat connection which is used to connected with CPU, the longest distance can be 200meters between the CPU and the end expansion module.

Removal

To remove xLogic:

....... if you have installed only one xLogic Basic:

Insert a screwdriver into the eyelet at the bottom of the slide interlock and move the latch downward.
Swing the xLogic Basic off the DIN rail.

....... if you have connected at least one expansion module to xLogic Basic:

Remove the connector on the flat cable
Slide the expansion module off towards the right.
Insert a screwdriver into the eyelet at the bottom of the slide interlock and lever it downward.
Swing the expansion module off the profile rail.

Repeat steps 1 to 4 for all other expansion modules.

3.2 Wall-mounting

For wall-mounting, first slide the mounting slides on the rear side of the devices towards the outside. You can now wall-mount xLogic by means of two mounting slides and two ØM4 screws (tightening torque 0.8 to 1.2 Nm).

Drilling template for wall-mounting

Before you can wall-mount xLogic, you need to drill holes using the template shown below.

All dimensions in mm

Bore hole for Ø M4 screw, tightening torque 0.8 to 1.2 Nm

PR-24 series

ELC-12-N series(applied to CPU and extensions):

3.^{^[1]} wiring xLogic

Wire the xLogic using a screwdriver with a 3-mm blade.

You do not need wire ferrules for the terminals. You can use conductors with cross-sections of up to the following thicknesses:

l 1 x 2.5 mm²

l 2 x 1.5 mm²for each second terminal chamber

l Tightening torque: 0.4.. .0.5 N/m or 3. ..4 lbs/in

Note

Always cover the terminals after you have completed the installation. To protect xLogic adequately from impermissible contact to live parts, local standards must be complied with.

Note

A power failure may cause an additional edge triggering signal.

Data of the last uninterrupted cycle are stored in xLogic To connect xLogic to the power supply:

3.4.2 Connecting xLogic inputs

Requirementsthe inputs you connect sensor elements such as: momentary switches, switches, light barriers, daylight control switches etc.

	AC Type	DC Type
Signal status 0	<40VAC <0.03mA	<5VDC <0.1mA
Input current Signal status 1	>79VAC Typical 0.06	>10VDC Typical 0.3mA
Input current	0.24mA
Analogue input	NO	AI1-AI4(0-10V DC)(PR-6,PR-12)
Note: 1. For PR-6DC-DA-R, PR-12DC-DA ,PR-14DC-DA, PR-18DC-DA ,PR-24DC-DA Series and versions. That can receive analog input. They can be set to analog input or digital input as either may be used in the program. They will be recognized as analog inputs when the input terminal is connected with an analog function block, and they will be recognized as switching inputs when the input terminal is not connected with an analog function block. 2. The analog inputs require DC 0V ~ +10V voltage signals. These are divided equally in 0.01V increments. In programming, all the block parameters related to the analog inputs are based on the minimum increment of 0.01V. 3. They can be recognized as switching input when the input voltage is more than 10.0V and cannot be recognized as an analog input. 4. For the switching input off, when the switch status changes from 0 to 1, the time of Status 1 must be greater than 50ms, and when the switch status changes from 1 to 0, the time of Status 0 also must be greater than 50ms.

Connecting xLogic is shown as in the following figures:

* DC type digital inputs

* AC type digital inputs

* Analog Inputs (DC 0…10V)

*Analog inputs current Inputs (0…20mA)

The above figure shows how to make a four-wire current measurement.

PR-E-PT100

It can be connected with one two-wire or three-wire resistance-type thermocouple.

When two-wire technology applied, the terminals “M1+ and IC1” (this rule also shall be applied to” M2+ and IC2”, “M3+ and IC3” ) would be short connected. Such connection can not compensate error/tolerance caused by the resistance in measurement loop. The measurement error of 1 Ω impedance of power cord is proportional to +2.5 °C

The three-wire technology can inhibit the influence of measurement results caused by cable length (ohmic resistance).

2-wire （short circuit M+ and Ic) 3 wire

3.4.3 Connecting xLogic Outputs

Requirement for the relay output

Various loads such as lamp, fluorescent tube, motor, contact, etc., can be connected to the outputs of xLogic. The maximum ON output current that can be supplied by xLogic is 10A for the resistance load and 3A for the inductive load. The connection is in accordance with the following figure:

Requirement for the electronic transistor output:

The load connected to xLogic must have the following characteristics:

* The maximum switch current cannot exceed 0.3A.

* When the switch is ON (Q=1), the maximum current is 0.3A.

Notes (PNP):

* The load connecting voltage must be ≤60VDC and it must be DC.

* The “+” terminal of the output wiring must be connected with the DC positive voltage, and it must be connected with the “L+” terminal of the xLogic power ，a load must be connected with the “-” terminal of the DC negative voltage.

PR-E-AQ-VI(DC0..10V analog output).

EXM-E-AQ-I /PR-E-AQ-VI

PR-RS485

Actually, PR-RS485 is just a converter with photo isolation bringing out 3 wiring terminals(short circuited inner of such 3 terminals, so only one channel RS485 bus is available) from RS485 port (2x8pin) of CPU(PR-18/ELC-22/PR-24) for your easy connection with other devices.

If “RT1”, RT2” terminal are short connected, one 120R resistor will be connected between A/+ and B/-

4.3.4 How to set address of CPU and expansion module

Set CPU address

If there are more than one CPU in a certain communication network,well then the address of CPU must be set differently each other. You can change the address of CPU via xLogicsoft, or via the panel key if the

CPU with LCD panel. The address range is from 1 to 247 for ELC and PR series CPU

Confirm with "OK"

Change the address with arrow keys, and confirm with "Ok".

The CPU address also can be set by xlogicsoft, if the CPU without HMI, you only can set the expansion address with such method.

You can set the CPU address by the menu Tools-> transfer-> set PLC’s address in xlogicsoft.

Part 2 ：Set address of PR-E extensions.(PR-E-16DC-DA-R etc..)

Plastic slice

Step 1: Using a screwdriver , take the plastic slice down and we’ll find a dial switch.

2: Dial the switch as the below instructions to set the address what you need.

Up to 8 extensions (includes IO ,AQ,AI,PT100 modules) can be connected with the CPU .

The default address of PR-E extensions is 1 and the dial switch as below:

Address 1:

means the switch position

Address 2:

Address 3:

Address 4:

Address 5:

Address 6:

Address 7:

Address 8:

Notes:

1.The address setup of the extension module must be before powering on. Modification when powering on will be ineffective.

2.Freely connection with CPU and expansion , do not care the power supply type of CPU and extensions ,that means the AC type module also can be connected with the DC type module or AC type expansion module also can be connected with DC type CPU.

3.If the communication is established between CPU and extensions , the indicator on the top of the extensions’ house will turn to RUN(green color)(If the LED is red, that means the CPU cannot get communication with it).

4.If more than one expansion module connect to CPU at the same time ,the address of expansion module must be different each other, otherwise the system(CPU+expansions) would run abnormal, but if the expansion already has each own separately address, then the installation sequence of the expansion is not important anymore, for example you can let the expansion with address 8 as the first one with CPU.

The xLogic alternative

As you can see, xLogicsoft represents an alternative to conventional engineering methods:

You start by developing the circuit program on your desktop.
You simulate the circuit program on your computer and verify its functions, before you actually implement it in your system.
You can add comments to the circuit program and create hard-copies.
You save a copy of your circuit program to the file system on your PC, to make it directly available for any modifications.
It takes only a few key actions to download the circuit program to xLogic.
Under Simulate mode in xLogicsoft, you can study how to program via the panel

key.

5.1 xLogic Functions

PR series adapts programming methods by means of function blocks. A total of 9 general function blocks, 60 special function blocks, and 11 input & output function blocks are configured. And each block can achieve a specific control function independently, e.g. TOND, TOFD, SBPL, TBPL, SCHD, etc. As several blocks are linked up in a specific way, relatively complicated control functions can be performed. Programming with function blocks is simpler and better appreciated than the conventional PLC instruction programming.

The following types of operator for xLogic function blocks are available for options：

5.2 General Input & Output functions

5.2.1 Inputs

Fashion: Classic:

Input blocks represent the input terminals of xLogic. Up to 4 digital inputs(ELC-6 CPU),8(PR-12 CPU) , 76 inputs(PR-18 ) 78 inputs(ELC-22) and 80 inputs(ELC-26) are available to you.

In your block configuration, you can assign an input block a new input terminal, if this terminal is not already used in the circuit program.

Note:

I11 means the I1 input of the expansion with address 1.

I85 means the I5 input of the expansion with address 8.

5.2.2 Cursor keys

Fashion: Classic:

Up to four cursor keys are available to you. Cursor keys are programmed for the circuit program in the same ways as other inputs. Cursor keys can save switches and inputs, and allow operator control of the circuit program.

Switch the screen to current page(above shows) by pressing the Left or Right key, and press ESC key and arrow keys at the same time, then the corresponding cursor keys will turn on and give off a high trigger!

5.2.3 Outputs

Fashion: Classic:

Output blocks represent the output terminals of xLogic. You can use up to 2 outputs(ELC-6), 4 outputs(PR-12),70 outputs(PR-18), 72 outputs(PR-22),74 outputs(PR-26). In your block configuration, you can assign an output block a new terminal, provided this terminal is not already used in your circuit program.

The output always carries the signal of the previous program cycle. This value does not change within the current program cycle.

Note:

Q11 means the Q1 output of the expansion with address 1.

Q85 means the Q5 output of the expansion with address 8.

5.2.4 Permanent logical levels HI and LO

Fashion: Classic:

Set the block input to logical hi (hi = high) to set it permanently to logical '1' or 'H' state.

Fashion: Classic:

Set the block input to logical lo (lo = low) to set it permanently to logical '0' or 'L' state.

5.2.5 Panel Key

Fashion: Classic:

It is the symbol of the Function key on the panel (F1—F4). If one of the function keys is pressed down, the status of the corresponding symbol in the program shall turn from 0 to 1. And it shall give off one high trigger.

Notes: 1.Only one function key is allowed to be pressed down at any one time, if you press down two or more at the same time, xLogic does not process.

If the arrowkeys(UP, DOWN, LEFT and RIGHT), Esc and OK had been applied to the program, then they would be invalid for menu operation (e.g. manual programming,parameters modification and view alarming message etc).

5.2.6 Shift register bits

Fashion: Classic:

xLogic provides the shift register bits S1 to S8, which are assigned the read-only attribute in the circuit program. The content of shift register bits can only be modified by means of the Shift register special function

5.2.7 Analog inputs

Fashion: Classic:

You can use up to 36 analog inputs. In your block configuration, you can assign a new input terminal to an input block, provided this terminal is not already used in the circuit program.

For help on analog block parameter, refer to Information on analog value processing.

Note:

AI11 means the AI1 input of the expansion with address 1.

AI82 means the AI2 input of the expansion with address 8.

Based on different analog input signals, you need select different sensor type in the analog blocks, you need use an analog amplifier with the AI input, and select the corresponding sensor type for DC0..10V, 0/4..20mA or PT100 input.

5.2.8 F (digital flag)

Fashion: Classic:

Flags are used when xLogic works in a communication system. F is digital flag which is used to save /transfer signal 1 or 0(data format is Bit) and AF is analog flag which is used to save /transfer analog values (data format is Signed short) between the master and slave devices. Up to 32(ELC-6), 128(PR-12/ELC-22/ELC-26) can be used when programming. In your block configuration, you can assign a new number to the flag, provided this flag number does not already exist in your circuit program. The output always carries the signal of the previous program cycle. This value does not change if the communication has failed.

Startup flag: F8

The F8 flag is set in the first cycle of the user program and can thus be used in your circuit program as a startup flag. It is reset after the first program execution cycle.

In the subsequent cycles, the F8 flag reacts in the same way as the F1 to F64 flags.

Backlight flags: F64

The F64 flag controls the backlight of the xLogic display or the ELC-43T backlight.

You can use the outputs of timers, message texts, or other function blocks to activate the backlight flags. To enable multiple conditions to control the backlight of the devices, you can use multiple function blocks in parallel or in sequence. Buzzer of ELC-43TS control flag:F63

Notes: 1.The address of “ F“ can be found in the modbus communication protocol file . the F block figure must have the input pin in the xLogic showing.

Keep the input pin of FNULL(do not connect with other blocks) ,if you want to use the write property.

5.2.9 AF (Analog flag)

Fashion: Classic:

Flags are used when xLogic works in a communication system. AF is analog flag which is used to save

/transfer analog values (data format is Signed short) between the master and slave devices. Up to 32(PR-6) and 256(PR-12/PR-18/PR-24) for xLogic CPU can be used when programming. In your block configuration, you can assign a new number to the analog flag, provided this flag number does not already exist in your circuit program.

The output always carries the signal of the previous program cycle. This value does not change if the communication were failed.

Notes: 1.The address of “AF“ can be found in the modbus communication protocol file .

2.Keep the input pin of AF NULL(do not connect with other blocks) ,if you want to use the write property.

You can set a start value for the AF1--AF64(PR-12/PR-18/PR-24), and the value does not lost if the power was failure, so you can use such AF in your program as a number input from the touch screen or the panel key of the CPU.

Notes: 1.AF65--AF256 does not support such function(start value settings). and the value of AF65--AF256 will be lost if the power is failure.

If you enable the "start value option" of AF, then you are not allowed to connect any other function to the input leg of the AF.
If you connect the input leg of AF block to other function blocks, the "start value" will not be available anymore.

5.3 Basic functions list – GF

Basic functions represent simple logical elements of Boolean algebra.

You can invert the inputs of individual basic functions , i.e. the circuit program inverts a logical “1” at a relevant input to a logical “0”; if “0” is set at the input, the program sets a logical “1”.

The GF list contains the basic function blocks you can use for your circuit program. The following basic functions are available:

5.3.8 NOT

Fashion: Classic:(Symbol in xLogic)

The output is 1 if the input is 0. The NOT block inverts the input status.

Advantage of the NOT, for example: xLogic no longer requires break contacts. You simply use a make contact and convert it into a break contact with the help of the NOT function.

Logic table of the NOT function:

Input 1		Output
0	1
1	0

5.3.9 Boolean Function

Fashion: Classic:

The BOOLEAN function gives the value of the output according to the combination of inputs. The function has four inputs, and therefore 16 combinations. These combinations can be found in a truth table; for each of these, the output value can be adjusted. The number of configurable combinations depends on the number of inputs connected to the function.

Non-connected inputs are set to 0.

The following diagram shows an example of part of the Boolean function truth table:

Parameters

Having connected at least one input, you can configure the value of the output in the truth table, in the Parameters window.

The output values can be 0 for the Inactive state, and 1 for the Active state(Double click to change the 0 or 1 ).

By selecting the Output ON if result is TRUE option, the output takes the value configured in the truth table.

By selecting the Output OFF if result is TRUE option, the output takes the inverse value of the value configured in the truth table.

5.4 Basics on special functions

Because of their different input designation, you can see right away that there is a difference between the special functions and basic functions. SFs contain timer functions, retentive functions and various parameter assignment options, which allow you to adapt the circuit program to suit your own requirements.

This section provides you with a brief overview of input designations and with some particular background information on SFs. The SFs in particular are described in Chapter7.5

5.4.1 Designation of the inputs

Logical inputs

Here, you will find the description of the connectors you can use to create a logical link to other blocks or to the inputs of the xLogic unit.

S (Set):

A signal at input S sets the output to logical “1”.

R (Reset):

The reset input R takes priority over all other inputs and resets the outputs.

Trg (Trigger):

This input is used to trigger the start of a function.

Cnt (Count):

This input is used for counting pulses.

Fre (Frequency):

Frequency signals to be evaluated are applied to this input.

Dir (Direction):

This input determines the direction of count.

En (Enable):

This input enables a block function. When this input is “0”, other signals to the block will be ignored.

Inv (Invert):

A signal at this input inverts the output signal of the block.

Ral (Reset all):

All internal values are reset.

Parameter inputs

At some of the inputs you do not apply any signals. You configure the relevant block values instead.

Examples:

Par (Parameter):

This input will not be connected. Here, you set the relevant block parameters (times, on/off thresholds etc.).

No (Cam):

This input will not be connected. Here, you configure the time patterns.

P (Priority):

This is an open input. Here, you define priorities and specify whether a message is to be acknowledged in RUN.

5.4.2 Time response

Parameter T

In some of the SFs it is possible to configure a time value T. When you preset this time, note that your input values are based on the time base set:

Time base	_ _ :		_ _
s (seconds)	seconds	:	¹/100 seconds
m (minutes)	minutes	:	seconds
h (hours)	hours	:	minutes

Accuracy of T

Because of slight tolerances in the characteristics of electronic components, the set time T may deviate. The xLogic has a maximum tolerance of ± 0.02 %.

When 0.02 % of the time T is smaller than 0.02 seconds, the maximum deviation is 0.02 seconds. Example: The maximum tolerance per hour (3600 seconds) is ±0.02%, which is proportional to ± 0.72 seconds. The maximum tolerance per minute (60 seconds) is ± 0.02 seconds.

Accuracy of the timer (weekly/yearly timer)

The maximum timing in accuracy is ± 5 s/day.

5.4.3 Backup of the real-time clock

Because the internal real-time clock of an xLogic is backed up, it continues operation after a power failure. The ambient temperature influences the backup time. At an ambient temperature of 25°C, the typical backup time of xLogic is 100 hours.

6.4.4 Retentivity

The switching states and counter values of SFs can be set retentive. This means that current data is retained after a power failure, and that the block resumes operation at the break point. The timer is not reset, but resumes operation until the time-to-go has expired, for example, to enable this response, however, the relevant functions must be set retentive.

R: The data is retained.

/: Current data is not retained (default). See the section in topic "Second circuit program " on enabling and disabling retentivity.

SFs hours counter, weekly timer, yearly timer and PI controller are always retentive.

5.4.5 Parameter protection

In the parameter protection settings, you can determine whether or not the parameters can be displayed and edited in xLogic parameter assignment mode. Two options are available:

+: The parameter attribute permits read/write access in parameter assignment mode(default).

-: The parameter settings are read–/write–protected in parameter assignment mode, and can be edited only in programming mode. See the parameter protection mode example in the "Second circuit program".

5.4.6 Calculating the gain and offset of analog values

A sensor is connected to the analog input and converts a process variable into an electrical signal. This value of signal lies within the typical range of this sensor. xLogic always converts the electrical signals at the analog input into digital values from 0 to 1000. A voltage of 0 to 10 V (or current signal 0/4…20mA) at input AI is transformed internally into range of values from 0 to 1000. An input voltage exceeding 10 V is shown as internal value 1000.

Because you cannot always process the range of values from 0 to 1000 as predetermined by xLogic, you can multiply the digital values by a gain factor and then shift the zero of the range of values (offset). This allows you to output an analog value to the xLogic display, which is proportional to the actual process variable.

Parameter	Minimum	Maximum
Input voltage (in V)	0	≥ 10
Input current(in mA)	0/4	≥20
Internal value	0	1000
Gain	–10.00	+10.00
Offset	–10000	+10000

Mathematical rule

Actual value Ax =

(internal value at input Ax∙gain) + offset

Gain and offset calculation

The gain and offset is calculated based on the relevant high and low values of the function.

Example 1:

The available thermocouples have the following technical data: –30 to +70℃, 0 to 10 V DC (i.e. 0 to 1000 in xLogic).

Actual value = (internal value ∙gain) + offset, thus

–30 = (0 ∙A) + B, i.e. offset B = –30 +70 = (1000 ∙A) –30, i.e. gain A = 0.1

Example 2:

A pressure sensor converts a pressure of 1000 mbar into a voltage of 0 V, and a pressure of 5000 mbar into a voltage of 10 V.

Actual value = (internal value. gain) + offset, thus = (0·A) + B, i.e. offset B = 1000

=（1000 ∙A) +1000, i.e. gain A = 4

Example of analog values

Process variable	Voltage (V)	Internal value	Gain	Offset	Value shown
–30⁰C	0	0	0.1	–30	(Ax) –30
0⁰C	3	300	0.1	–30	0
+70⁰C	10	1000	0.1	–30	70
1000 mbar	0	0	4	1000	1000

5000 mbar	10	1000	4	1000	5000
	0	0	0.01	0	0
	5	500	0.01	0	5

5.5 Special functions list – SF

When you create your circuit program in xLogicsoft, you find the special function blocks in the SF list. You can invert the inputs of SFs individually, i.e. the circuit program converts a logical “1” at the input into a logical “0”; alogical“0”itconvertsintoalogical“1”.The table also specifies whether the relevant function can be set retentive (Rem). The following SFs are available:

5.5.1 On-delay

Fashion: Classic:

Short description

	Multiplexer
	Square root
	Sin Cos

The output is not switched on until a configured delay time has expired.

Connection	Description
Trg input	The on delay time is triggered via the Trg (Trigger) input
Parameter	T represents the on delay time after which the output is switched on (output signal transition 0 to 1). Retentivity on = the status is retentive in memory.
Output Q	Q switches on after a specified time T has expired, provided Trg is still set.

Parameter T

The time for parameter T can also be preset based on the actual value of another, already-configured function. You can use the actual values of the following functions:

Analog comparator: Ax - Ay

Analog trigger: Ax

Analog amplifier: Ax

Analog multiplexer: AQ Analog ramp: AQ

Analog math: AQ

PI controller:AQ

Data latching relay: AQ

Up/Down counter: Cnt

You select the required function via the block number. Time-base can be adjusted.

The value of ＂T＂ can be set/modified in parameter mode. For information about how to modify，refer

to chapter 5.2.2 please.

For information on the validity and accuracy of the time base, refer to the xLogic time-base list as follows:

Valid ranges of the time-base, if T = parameter

Time-base	Max. value	Min. resolution	Accuracy
s (seconds)	99:99	10 ms	± 10 ms
m (minutes)	99:59	1s	± 1 s
h (hours)	99:59	1 min	± 1 min

Valid ranges of the time base, if T = Actual value of an already-programmed function

Timing diagram

Description of the function

The time Ta (the current time in xLogic) is triggered with the 0 to 1 transition at input Trg.

If the status at input Trg stays 1 at least for the duration of the configured time T, the output is set to 1 when this time has expired (the on signal of the output follows the on signal of the input with delay).

The time is reset if the status at input Trg changes to 0 again before the time T has expired.

The output is reset to 0 when input Trg is 0.

5.5.2 Off-delay

Fashion: Classic:

Short description

The output with off delay is not reset until a defined time has expired.

Connection	Description
Input Trg	Start the off delay time with a negative edge (1 to 0 transition) at input Trg (Trigger)
Input R	Reset the off delay time and set the output to 0 via the R (Reset) input. Reset has priority over Trg
Parameter	T: The output is switched off on expiration of the delay time T (output signal transition 1 to 0). Retentivity on = the status is retentive in memory.
Output Q	Q is switched on for the duration of the time T after a trigger at input Trg.

Parameter

The time set in parameter T can be supplied by the value of another already-programmed function:

Analog comparator: Ax - Ay

Analog trigger: Ax

Analog amplifier: Ax

Analog multiplexer: AQ

Analog ramp: AQ

Analog math: AQ

PI controller:AQ

Data latching relay: AQ

Up/Down counter: Cnt

The value of ＂T＂can be set/modified in parameter mode. For information about how to modify, refer to chapter 5.2.2 please.

Select the required function by the block number. The time base is configurable. For information on valid time base ranges and parameter preset, refer to chapter 4.4.1 the On-delay topic.

Timing diagram

Description of the function

Output Q is set to 1 momentarily with a 0 to 1 transition at input Trg.

At the 1 to 0 transition at input Trg, xLogic retriggers the current time T, and the output remains set. The output Q is reset to 0 when T_areaches the value specified in T (T_a=T) (off delay).

A one-shot at input Trg retriggers the time Ta.

5.5.11 Weekly timer

Fashion: Classic:

Caution

Your xLogic must be equipped with an internal real-time clock if you are going to use this SFB.

Short description

The output is controlled by means of a configurable on/off date. The function supports any combination of weekdays.

Connection	Description
Parameter	At the No1, No2, No3 (cam) parameters you set the on and off triggers for each cam of the weekly timer. The parameter units are the days and the time-of-day.
Output Q	Q is set when the configured cam is actuated.

Parameter

You can configure a time hysteresis for each individual cam in parameter mode. For information about how to modify, refer to chapter 4.2.2 please. Timing diagram (three practical examples)

No1: Daily: 06:30 h to 08:00 h

No2: Tuesday: 03:10 h to 04:15 h

No3: Saturday and Sunday: 16:30 h to 23:10 h

Description of the function

Each weekly timer is equipped with three cams. You can configure a time hysteresis for each individual cam. At the cams you set the on and off hysteresis. The weekly timer sets the output at a certain time, provided it is not already set.

The output is reset at a certain time, provided it is not already reset. A conflict is generated in the weekly timer when the set on time and the set off time at another cam are identical. In this case, cam 3 takes priority over cam 2, while cam 2 takes priority over cam 1.

The switching status of the weekly timer is determined by the status at the No1, No2 and No3 cams.

Days of the week

The prefix "D=" (Day) has the following meaning:

M: Monday
T: Tuesday
W: Wednesday
T: Thursday
F: Friday

On-/Off-times

Any time between 00:00 h and 23:59 h is possible. You can also configure the on time to be a pulse signal. The timer block will be activated at the specified time for one cycle and then the output is reset.

- -:- - means: No on-/off-times set.

Setting the weekly timer To set the on-/off-times:

Move the cursor to one of the Cam parameters of the timer (e.g. No1).
Press OK. xLogic opens the Cam parameter assignment screen form. The cursor is positioned on the day of the week.
Pressand to select one or several days of the week.
Press to move the cursor to the first position of the on-time.
Set the on-time.

Modify the value at the respective position, using the keys . Move to the cursor to the various positions, using the keys . At the first position, you can only select the value - -:- -

(- -:- - means: No on-/off-times set).

Press to move the cursor to the first position of the off-time.
Set the off-time (in same way as in step 5).
Confirm your entries withOK.

The cursor is now positioned on the No2 parameter (Cam2) and you can configure a further cam.

Special characteristics to note when configuring

The block properties window offers a tab for each one of the three cams. Here you can set the weekly on times for the cams. Each tab offers you in addition an option of defining the on and off times for each cam in hour and minute units. Hence, the shortest switching cycle is one minute.

You can disable the on and off times individually, i.e. you can achieve switching cycles extending across more than one day, for example, by setting the on time for cam 1 to Monday 7:00 h and the off time of cam 2 to Wednesday 13:07 h, while disabling the on time for cam 2.

Backup of the real-time clock

The internal real-time clock of xLogic is buffered against power failure. The buffering time is influenced by the ambient temperature, and is typically 100 hours at an ambient temperature of 25°C.

In order to set the weekly timer parameters through MODBUS, now the parameters of the weekly Timer can use the AF value. Weekday parameter.

For example use AF1

AF is 16 bits type value, the weekday use the low 8 bits status as the parameters:

bit7 bit6 bit5 bit4 bit3 bit2 bit1 bit0 0(Reserved) SAT FRI THU WED TUE MON SUN

You can program as above, use one Bit to word block and then, you can set the F1--F7 at the touch screen to change the weekday settings.

On time/Off Time settings--Reference AF value.

For example If AF2 =800, then the settings is equal to 08:00;

AF2=2105, then the On time would be 21:05;

If AF3=1023, then the OFF time would be 10:23; Note:

If the AF value is over 2323, it will be not available for the On/Off time, the output of the weekly timer will be 0.

5.5.12 Yearly timer

Fashion: Classic:

Caution

Your xLogic must be equipped with an internal real-time clock if you are going to use this SFB.

Short description

The output is controlled by means of a configurable on/off date

Connection	Description
Parameter	At the No (cam) parameter you set the on and off trigger for the cam of the yearly timer.
Output Q	Q is set on when the configured cam is switched on.

Parameter

The on and off trigger for the cam of the yearly timer can be set/modified in parameter mode and you can configure what you need. For information about how to modify, refer to chapter 5.2.2 please.

Timing diagrams

Example 1: Yearly mode on, Monthly mode off, Pulse Off, On Time = 2000-06-01, Off Time =

2099-08-31: Every year on June 1 the timer output switches on and remains on until August 31.

Example 2: Yearly mode on, Monthly mode off, Pulse on, On Time = 2000-03-15, Off Time = 2099-**-**: Every year on March 15, the timer switches on for one cycle.

Example 3: Yearly mode on, Monthly mode off, Pulse off, On Time = 2008-06-01, Off Time = 2010-08-31: On June 1 of 2008, 2009, and 2010 the timer output switches on and remains on until August 31.

Example 4: Yearly mode on, Monthly mode off, Pulse on, On Time = 2008-03-15, Off Time =

2010-**-**: On March 15 of 2008, 2009, and 2010, the timer output switches on for one cycle.

Example 5: Yearly mode off, Monthly mode off, Pulse off, On Time = 2008-06-01, Off Time = 2008-08-31: On June 1, 2008 the timer output switches on and remains on until August 31, 2010.

Example 6: Yearly mode off, Monthly mode off, Pulse selected, On Time = 2008-03-15, Off Time = ****-**-**: On March 15, 2008 the timer output switches on for one cycle. Because the timer does not have a monthly action or yearly action, the timer output pulses only one time at the specified On Time.

Example 7: Yearly mode on, Monthly mode off, Pulse off, On Time = 2008-12-15, Off Time = 2010-01-07: On December 15 of 2008 and 2009, the timer output switches on and remains on until January 7 of the following year. When the timer output turns off on January 7, 2010 it does NOT turn on again the following December 15.

Example 8: Yearly mode on, Monthly mode on, On Time = 2008-**-01, Off Time = 2010-**05: Starting in 2008, on the first day of each month the timer output switches on and switches off on the fifth day of the month. The timer continues in this pattern through the last month of 2010.

Description of the function

The yearly timer sets and resets the output at specific on and off times.

The off-date identifies the day on which the output is reset again. The first value defines the month, the second the day.

When you select the every month check box, the yearly clock switches on or off at a certain day of every month.

Backup of the real-time clock

The internal real-time clock of xLogic is buffered against power failure. The buffering time is influenced by the ambient temperature, and is typically 100 hours at an ambient temperature of 25°C.

Special characteristics to note when configuring

A click on the dialog box enables direct keyboard input of the month and day values. The values entered may not exceed the logical maximum of the relevant input boxes; otherwise xLogicsoft returns an error message.

The calendar icon offers you an Rievtech way of setting the date. It opens a window where you can set the days and months by clicking the relevant buttons.

Sample configuration

The output of an xLogic is to be set annually on March 1, reset on April 4, set again on July 7, and reset again on November 19. You need to configure two yearly timers with corresponding on-times.

Then logically link the outputs by means of an OR block.

Yearly Timer 1 On-time Mar 1 Off-time Apr 4 Yearly Timer 2

On-time Jul 7

Off-time Nov 19

Result

Place two yearly timer switch SFBs on your programming interface and configure the blocks as specified.

Create a logical link of the blocks via a standard OR block. The OR output is 1 if at least one of the yearly timer switches is set.

5.5.13 Up/Down counter

Fashion: Classic:

Short description

An input pulse increments or decrements an internal value, depending on the parameter setting. The output is set or reset when a configured threshold is reached. The direction of count can be changed with a signal at input Dir

Connection	Description
Input R	You reset the output and the internal counter value to zero with a signal at input R (Reset).
Input Cnt	This function counts the 0 to 1 transitions at input Cnt. It does not count 1 to 0 transitions.
Input Dir	Input Dir (Direction) determines the direction of count: Dir = 0: Up Dir = 1: Down
Parameter	On: On threshold Value range: 0...99999999 Off: Off threshold Value range: 0...99999999 StartVal: Initial value from which to begin counting either down or up. Retentivity set (on) = the status is retentive in memory.
Output Q	Q is set and reset according to the actual value at Cnt and the set thresholds.

Parameter

Analog comparator: Ax – Ay

Analog trigger: Ax

Analog amplifier: Ax

Analog multiplexer: AQ

Analog ramp: AQ

Analog math: AQ

Data latching relay: AQ

Up/Down counter: Cnt

The value of ＂On＂，＂Off＂and ＂Cnt＂can be set/modified in parameter mode. For information about how to modify ,refer to chapter 5.2.2 please.

Timing diagram

Description of the function

The function increments (Dir = 0) or decrements (Dir = 1) the internal counter by one count with every positive edge at input Cnt.

You can reset the internal counter value to '000000', with a signal at the reset input R. As long as R=1, the output is 0 and the pulses at input Cnt are not counted.

Output Q is set and reset according to the actual value at Cnt and the set thresholds. See the following rules for calculation.

Calculation rule

If the on threshold >= off threshold, then:

Q = 1, if Cnt >= On Q = 0, if Cnt < Off.

If the on threshold < off threshold, then:

Q = 1, if On <= Cnt < Off.

Caution

The function polls the limit value of the counter once in each cycle.

Thus, if the pulses at the fast inputs are faster than the scan cycle time, the SFB might not switch until the so specified limit has been exceeded.

Example: Up to 100 pulses per cycle can be counted; 900 pulses have been counted so far. On = 950; Off = 10000. The output is set in the next cycle, after the value has reached 1000.

The output would not be set at all if the value Off = 980

5.5.14 Hours counter

Fashion: Classic:

Short description

A configured time is triggered with a signal at the monitoring input. The output is set when this time has expired.

Connection	Description
Input R	A positive edge (0 to 1 transition) at input R resets output Q and sets a configured value MI at the counter for the duration of the time-to-go (MN).
Input En	En is the monitoring input. xLogic scans the on-time of this input.
Input Ral	A positive edge at input Ral (Reset all) resets both the hours counter (OT) and the output, and sets the configured value MI at the counter to for the duration of the time-to-go (MN). That is, • Output Q = 0, • The measured operating hours OT = 0, and • The time-to-go of the maintenance interval MN = MI.
Parameter	MI: Maintenance interval to be specified in hour units Range of values: 0000...9999 h OT: Expired total operation time. An offset can be specified. Range of values: 00000...99999 h Q 0: • When "R" is selected: Q = 1, if MN = 0; Q = 0, if R = 1 or Ral = 1 • When "R+En" is selected: Q = 1, if MN = 0; Q = 0, if R = 1 or Ral = 1 or En = 0.
Output Q	The output is set when the time-to-go MN = 0. The output is reset: • When "Q 0:R+En", if R = 1 or Ral = 1 or En = 0 • When "Q 0:R", if R = 1 or Ral = 1.

Timing diagram

MI = Configured time interval

MN = Time-to-go

OT = Total time expired since the last 1 signal at the Ral input These values are principally held retentive!

Parameter

The maintenance interval MI can be provided by the actual value of another already-programmed function:

Analog comparator: Ax – Ay

Analog trigger: Ax

Analog amplifier: Ax

Analog multiplexer: AQ

Analog ramp: AQ Analog math: AQ

PI controller: AQ

Data latching relay: AQ

Up/Down counter: Cnt

The value of ＂ＭＩ＂ can be set and modified in parameter mode. For information about how to modify, refer to chapter 4.2.2 please.

Description of the function

The hours counter monitors input En. As long as the status at this input is 1, xLogic calculates the time expired and the time-to-go MN. xLogic displays these times when set to configuration mode. The output is set to 1 when the time-to-go is equal to zero.

You reset output Q and the time-to-go counter to the specified value MI with a signal at input R. The operation hour counter OT remains unaffected.

You reset output Q and the time-to-go counter to the specified value MI with a signal at input Ral. The operation hour counter OT is reset to 0.

Depending on your configuration of the Q parameter, the output is either reset with a reset signal at input R or Ral, or when the reset signal is 1 or the En signal is 0.

Limit value of OT

The values of the operating hours in OT are retained when you reset the hours counter with a signal at input R. The hours counter OT continues the count as long as En = 1, irrespective of the status at the reset input R. The counter limit of OT is 99999 h. The hours counter stops when it reaches this value.

Parameter preset

In xLogicsoft, you can define MI and an OT start value.

You determine that Q does not depend on En by selecting the corresponding check box.

Retentivity with the hours counter

The hours counter in the xLogic is generally retentive.

However, if the values of the hours counter are lost after a power failure, then select the respective block in your circuit program. Right mouse click on the hours counter and select Block Properties > Parameters. The option Retentivity must be activated and not changeable (grayed out).

If the Retentivity option is not available, then delete the block and insert a new special function hours counter at the same position.

5.5.16 Latching relay

Fashion: Classic:

Short description

A signal at input S sets output Q. A signal at input R resets output Q.

Connection	Description
Input S	Set output Q with a signal at input S (Set).
Input R	Reset output Q with a signal at input R (Reset). Output Q is reset if S and R are both set (reset has priority over set).
Parameter	Retentivity set (on) = the status is retentive in memory.
Output Q	Q is set with a signal at input S and remains set until it is reset with signal at input R.

No parameter of Latching relay can be set/modified in parameter mode .

Timing diagram

Description of the function

The latching relay represents a simple binary memory logic. The output value depends on the input states and the previous status at the output.

Logic table of the latching relay:

S		R		Q	Remark
0	0		x		Status unchanged
0	1		0		Reset
1	0		1		Set
1	1		0		Reset

When retentivity is enabled, the output signal corresponds with the signal status prior to the power failure.

5.5.17 Pulse relay

Fashion: Classic:

Short description

The output is set and reset with a short one-shot at the input.

Connection	Description
Input Trg	You switch output Q on or off with a signal at input Trg (Trigger) input.
Input S	A one-shot at input S (Set) sets the output to logical 1.
Input R	A one-shot at input R (Reset) resets the output to logical 0
Parameter	Selection: RS (input R priority), or SR (input S priority) Retentivity set (on) = the status is retentive in memory.
Output Q	Q is switched on with a signal at Trg and is reset again at the next Trg pulse, if both S and R = 0.

No parameter of Latching relay can be set/modified in parameter mode .

Timing diagram

Description of the function

The status of output Q changes with each 0 to 1 transition at input Trg and if both S and R = 0, i.e. the output is switched on or off.

Input Trg does not influence the SFB when S = 1 or R = 1.

A one-shot at input S sets the pulse relay, i.e. the output is set to logical 1.

A one-shot at input R resets the pulse relay to its initial state, i.e. the output is set to logical 0. Either the input R takes priority over input S (i.e. the signal at input S has no effect as long as R = 1), or the input S takes priority over input R (i.e. the signal at input R has no effect as long as S = 1), depending on your configuration.

5.5.18 Message text

Fashion: Classic:

Short description

Display parameterized message texts and parameters of other blocks in RUN mode.

Connection	Description
Input En	A 0 to 1 transition at En (Enable) triggers the output of the message text.
Input P	P is the priority of the message text. 1 is the lowest, 32 is the highest priority. Quit: Acknowledgement of the message text
Parameter	Text: Input of the message text Par: Parameter or actual value of another, already configured function (see "Visible parameters or actual values") Time: Shows the continuously updated time-of-day Date: Shows the continuously updated date EnTime: Shows the time of the 0 to 1 transition EnDate: Shows the 0 to 1 transition of the date
Output Q	Q remains set as long as the message text is queued.

Description of the function

With a 0 to 1 transition of the signal at input En, the display outputs your configured message text (actual value, text, TOD, date) in RUN mode.

Acknowledgement disabled (Ack = Off):

The message text is hidden with a 0 to 1 signal transition at input En.

Acknowledgement enabled (Ack = On):

After input En is reset to 0, the message text is displayed until acknowledged by pressing the OK button. The message text cannot be acknowledged as long as input En is high.

If several message text functions were triggered with En=1, the message with the highest priority (1 = lowest, 64=highest) is displayed. This also implies that a new message text is only displayed if its priority is higher than that of previously enabled message texts.

After a message text is disabled or acknowledged, the function automatically shows the previously active message text that takes the highest priority.

You can press the keys to step through multiple active message texts.

5.5.19 Softkey

Fashion: Classic:

Short description

This SFB provides the action of a mechanical pushbutton or switch.

Connection	Description
Input En	Output Q is set with a 0 to 1 signal transition at input En (Enable) and if, in addition, 'Status=On' has been confirmed in configuration mode.
Parameter	Type: Sets either a pushbutton action for one cycle or a switching action of the function. Status: On or Off state that is applied in the initial cycle after program startup, is retentivity is not set. Retentivity set (on) = the status is retentive in memory.
Output Q	Output Q remains set 1, as long as En=1 and the status at the parameter Type = Switch and Status = On. Output Q is set for the duration of one cycle if EN=1 and the status at the parameters Type = momentary (pushbutton) and Status = On.

Factory state

Default of 'Type' is 'momentary action switch'.

Timing diagram

Description of the function

The output is set, when input En is set and the 'Status' parameter is set to 'On' and confirmed with OK.

This action is performed irrespective of a configured switch or pushbutton function.

The output is reset to '0' in the following three cases:

With a 1 to 0 signal transition at input En.
When a pushbutton function is configured and one cycle has expired after its actuation.
When the 'Status' parameter sets the 'Off' status in configuration mode, and this has been confirmed with OK.

Particular characteristics to be noted when configuring

The softkey can be used both with momentary push button or switching action. At the status parameter you can define the on (actuated) or off state for the switch/push button.

If the softkey is assigned a push button action, the output is always set for the duration of one cycle with a 0 to 1 transition at input En when the push button is in on state, or if the push button state changes from Off to On when En=1.

Parameters of softkey in message texts block:

1.The “ok” means you can press the ok button to switch the status of the softkey block after its parameter inserted into message texts.

2.The “Esc” means you can press the ESC button to switch the status of the softkey block after its parameter inserted into message texts.

3.The status of softkey block is also can be inserted into the message texts block for displaying.

Connection	Description
Input In	The function when started reads this input value.
Input Trg	The SFB is started with a positive edge (0 t 1 transition) at input Trg (Trigger). A 1 to 0 transition is irrelevant.
Input Dir	You define the shift direction of the shift register bits S1...S8 at the Dir input: Dir = 0: shift up (S1 >> S8) Dir = 1: shift down (S8 >> S1)
Parameter	Shift register bit that determines the value of output Q. Possible settings: S1 ... S8 Retentivity set (on) = the status is retentive in memory.
Output Q	The output value corresponds with the configured shift register bit.

Timing diagram

Setting the Par parameter

This special function is not available in parameter assignment mode.

Description of the function

The function reads the value of input In with a positive edge (0 to 1 transition) at input Trg (Trigger).

This value is written to shift register bits S1 or S8, depending on the set shift direction:

Shift up: S1 accepts the value of input In; the previous value of S1 is shifted to S2, S2 is shifted to S3, etc.
Shift down: S8 accepts the value of input In; the previous value of S8 is shifted to S7, S7 is shifted to S6, etc.

Q outputs the value of the configured shift register bits.

If retentivity is not enabled, the shift function restarts at S1 or S8 after a power failure.

Note

The special function shift register can be used only once in the circuit program.

5.5.21 Analog comparator

Fashion: Classic:

Short description

The output is set and reset depending on the difference Ax - Ay and on two configurable thresholds.

Connection	Description
Inputs Ax, Ay	Input the analog signals of which you want to determine the delta at the inputs Ax and Ay. Use the analog inputs AI1...AI8, the analog outputs AQ1 and AQ2. AI1..AI8: 0 - 10 V corresponds with 0 - 1000 (internal value).
Parameter	A: Gain Range of values: ± 10.00 B: Zero offset Range of values: ± 10,000 On: On threshold Range of values: ± 20,000 Off: Off threshold Range of values: ± 20,000 p: Number of decimals Range of values: 0, 1, 2, 3
Output Q	Q is set or reset depending on the set thresholds.

Parameter p (number of decimals)

The on threshold On and the off threshold Off can be provided by the actual value of another already-programmed function:

Analog comparator: Ax – Ay

Analog trigger: Ax

Analog amplifier: Ax

Analog multiplexer: AQ

Analog ramp: AQ

Analog math: AQ

PI controller: AQ

Data latching relay: AQ

Up/Down counter: Cnt

Applies only to Ax, Ay, Delta, On and Off values displayed in a message text.

Does not apply to the comparison of on and off values! (The compare function ignores the decimal point.) The value of ＂On＂,＂Off＂and ＂Dec＂ can be set/modified in parameter mode. For information about how to set/modify, refer to chapter 5.2.2 please.(Dec means decimal point.)

Timing diagram

Q for Ax - Ay > 200, On = Off = 200

Description of the function

The function reads the value of the signal at the analog input Ax.

This value is multiplied by the value of parameter A (gain). Parameter B (offset) is added to the product, hence

(Ax ∙ gain) + offset = Actual value Ax.

(Ay ∙ gain) + offset = Actual value Ay.

Output Q is set or reset depending on the difference of the actual values Ax - Ay and the set thresholds.

See the following calculation rule.

Calculation rule

If threshold On ≥Threshold Off, then:

Q = 1, if (actual value Ax - actual value Ay) > On Q = 0, if (actual value Ax - actual value Ay) ≤Off.

If threshold On < Threshold Off, then Q = 1, falls:

On ≤ (actual value Ax - actual value Ay) < Off.

Reducing the input sensitivity of the analog comparator

You can delay the output of the analog comparator selectively by means of the "on delay" and "off delay" SFBs. By doing so, you determine that output Q is only set if the input trigger length Trg (= output of the analog comparator) exceeds the defined on delay time.

This way you can set a virtual hysteresis, which renders the input less sensitive to short changes.

Particular characteristics to be noted when configuring

For help on analog block parameters, refer to the Analog value processing section in xLogicsoft.

Setting the Par parameter

The gain and offset parameters are used to adapt the sensors to the relevant application.

Example

In a heating control system, the supply Tv and return line temperatures Tr are to be compared, for example with a sensor at AI2.

A control signal is to be triggered (for example "heater On") when the difference between the supply and return line temperatures is greater than 15 °C. The control signal is reset when the difference is less than 5 °C.

The process variable of the temperature is to be shown in parameter assignment mode.

The thermocouples available have the following technical data: -30 to +70 °C, 0 to 10 VDC.

Reducing the input response of the analog comparator

You can selectively delay the output of an analog comparator by means of the "On-delay" and "Off-delay" special functions. With on-delay, output Q is only set if the pulse width of the triggering signal at input Trg (=analog comparator output) is longer than the on-delay time. Using this method, you will obtain a virtual hysteresis and reduce the input response to short signals.

parameter	A: Gain Range of values: +- 10.00 B: Zero offset Range of values: +- 10,000 PT: Periodic time over which the digital output is modulated p: Number of decimals Range of values: 0, 1, 2, 3
Output Q	Q is set or reset for the proportion of each time period according to the proportion of the standardized value Ax to the analog value range.

Parameter PT

The periodic time PT can be provided by the actual value of another already-programmed function:

Analog comparator: Ax – Ay

Analog trigger: Ax

Analog amplifier: Ax

Analog multiplexer: AQ

Analog ramp: AQ

PI controller: AQ

Analog math: AQ

Data latching relay: AQ

Up/Down counter: Cnt

Parameter p (number of decimals)

Parameter p applies only to the display of the Ax value in a message text.

Description of the function

The function reads the value of the signal at the analog input Ax.

This value is multiplied by the value of parameter A (gain). Parameter B (offset) is added to the product, as follows:

(Ax * Gain) + Offset = Actual value Ax

The function block calculates the proportion of the value Ax to the range. The block sets the digital output Q high for the same proportion of the PT (periodic time) parameter, and sets Q low for the remainder of the time period.

Examples with Timing Diagrams

The following examples show how the PWM instruction modulates a digital output signal from the analog input value:

Example 1

Analog input value: 500 (range 0...1000)

Periodic time T: 4 seconds

The digital output of the PWM function is 2 seconds high, 2 seconds low, 2 seconds high, 2 seconds low and continues in that pattern as long as parameter "En" = high.

Example 2

Analog input value: 300 (range 0...1000)

Periodic time T: 10 seconds

The digital output of the PWM function is 3 seconds high, 7 seconds low, 3 seconds high, 7 seconds low and continues in that pattern as long as parameter "En" = high.

Calculation rule

Q = 1, for (Ax – Min) / (Max – Min) of time period PT

Q = 0, for PT – [(Ax – Min) / (Max – Min)] of time period PT.

Note: Ax in this calculation refers to the actual value Ax as calculated using the Gain and Offset. Min and

Max refer to the minimum and maximum values specified for the range

Special feature.

Generally, the output frequency could be up to 30Hz But the Q3,Q4 of PR-12 type,Q5,Q6 of ELC-18/22/26 (PNP transistor output) CPU,Q7,Q8 of PR-24 could be up to 10KHZ and the property dialog box of PWM function block setting as follows:

If the special output is selected in the property dialog box of PWM block, then the unit of “periodic time” will be changed from s:1/100s to s:1/1000s, so if you input 3 (1/1000s) , then its frequency is 1000/3 Hz.

Notes:

The periodic time must be no less than 3 ms.
If the specific output is selected in the property dialog box of PWM block, then the output pin of PWM function block cannot be linked as input to other blocks.
Q3, Q4 in the above dialog box are exactly corresponding to Q3, Q4 of ELC-12 CPU and Q5,Q6 of ELC-22/26 and upgraded ELC-18 CPUs
Common speed output allow the frequency different for Q3&Q4 of ELC-12 CPU and Q5&Q6 of

ELC-22/26 and upgraded ELC-18 CPUs; But if the high speed ticked in the dialog box then the frequency settings must be same for Q3&Q4 of ELC-12 CPU and Q5&Q6 of ELC-22/26 and upgraded ELC-18 CPUs.

5.5.29 Analog Ramp

Fashion: Classic:

Short Description:

The Analog Ramp instruction allows the output to be changed from the current level to a selected level at a specified rate.

Connection	Description
Input En	A change in the status from 0 to 1 at input EN (Enable) applies the start/stop level (Offset "B" + StSp) to the output for 100 ms and starts the ramp operation to the selected level. A change in the status from 1 to 0 immediately sets the current level to Offset "B", which makes output AQ equal to 0.
Input Sel	SeI = 0: The step 1 (level 1) is selected. SeI = 1: The step 2 (level 2) is selected. A change in status of Sel causes the current level to start changing to the selected level at the specified rate.
Input St	A change in the status from 0 to 1 at input St (Decelerated Stop) causes the current level to decrease at a constant rate until the start/stop level (Offset "B" + StSp) is reached. The start/stop level is maintained for 100 ms and then the current level is set to Offset "B", which makes output AQ equal to 0.

Value range: -10,000 to +20,000 StSp: Start/Stop offset: value that is added to Offset "B" to create the start/stop level. If the Start/Stop offset is 0, then the start/stop level is Offset "B"). Value range: 0 to +20,000 Rate: Speed with which level 1, level 2 or 0ffset is reached. Steps/seconds are issued. Value range: 1 to 10,000 A: Gain Value range: 0 to 10,00 B: Offset Value range: +- 10.000 p: Number of decimal places Value range: 0, 1, 2, 3
Output AQ	The output AQ is scaled using the formula: (Current Level - Offset "B") / Gain "A" Note: When AQ is displayed in parameter mode or message mode, it is displayed as an un-scaled value (engineering units: current level). Value range for AQ: 0...+32767

Parameter p (number of decimal places)

The level parameters Level1 and Level2 can be provided by the value of another already-programmed function:

Analog comparator: Ax – Ay

Analog trigger: Ax

Analog amplifier: Ax

Analog multiplexer: AQ

Analog ramp: AQ

Analog math: AQ

PI controller: AQ

Data latching relay: AQ

Up/Down counter: Cnt

Parameter p only applies for displaying the values of AQ, level 1, level 2, MaxL, StSp, and Rate in a message text.

Timing diagram for AQ

Description of function

If the input En is set, then the function sets the value StSp + Offset "B" for 100 ms.

Then, depending on the connection of Sel, the function runs from the level StSp + Offset "B" to either level 1 or level 2 at the acceleration set in Rate.

If the input St is set, the function runs to a level of StSp + B at the acceleration set in Rate. Then the function holds the level at StSp + Offset "B" for 100 ms. After 100 ms, the level is set to Offset "B". output AQ. The scaled value (output AQ) is 0.

If the input St is set, the function can only be restarted once the inputs St and En have been reset. If input Sel has been changed, depending on the connection of Sel, the function runs from the current target level to the new target level at the rate that is specified.

If the input En is reset, the function immediately sets the current level to Offset "B".

The current level is updated every 100 ms. Note the relationship between output AQ and the current level:

Output AQ = (current level – Offset "B" ) / Gain "A"

5.5.30 Analog Math

Fashion: Classic:

Short Description

The analog math block calculates the value AQ of an equation formed from the user-defined operands and operators.

Connection	Description
Input EN	Enable the analog math function block.
Parameter	V1:Value 1: First operand V2: Value 2: Second operand V3: Value 3: Third operand V4: Value 4: Forth operand Operator 1: First operator Operator2: Second operator Operator 3: Third operator Priority 1: Priority of first operation Priority 2: Priority of second operation Priority 3: Priority of third operation P: number of decimals Range of values: 0,1,2,3
Output AQ	The output AQ is the result of the equation formed from the operand values and operators. AQ will be set to 32767 if a divide by 0 or overflow occurs, and -32768 if a negative overflow (underflow) occurs.

Parameter p (number of decimals)

The values V1, V2, V3, and V4 can be provided by the actual value of another already-programmed function:

Analog comparator: Ax – Ay

Analog trigger: Ax

Analog amplifier: Ax

Analog multiplexer: AQ

Analog ramp: AQ

Analog math: AQ

PI controller: AQ

Data latching relay: AQ

Up/Down counter: Cnt

Parameter p applies to the display of V1, V2, V3, V4 and AQ in a message text.

Description of the function

The analog math function combines the four operands and three operators to form an equation. The operator can be any one of the four standard operators: +, -, *, or /. For each operator, you must set a unique priority of High ("H"), Medium ("M"), or Low ("L"). The high operation will be performed first, followed by the medium operation, and then by the low operation. You must have exactly one operation of each priority. The operand values can reference another previously-defined function to provide the value. The analog math function rounds the result to the nearest integer value.

The number of operand values is fixed at four and the number of operators is fixed at 3. If you need to use fewer operands, use constructions such as " + 0" or " * 1" to fill the remaining parameters. You can also configure the behavior of the function when the Enable parameter "En"=0. The function block can either retain its last value or be set to 0.

Possible errors: Zero division and overflow

If the analog math function block execution results in zero division or overflow, it sets internal bits that indicate the type of error that occurred. You can program an analog math error detection function block in your circuit program to detect these errors, and to control the program behavior as needed. You program one analog math error detection function block to reference one specific analog math function block.

Examples

The following tables show some simple example analog math block parameters, and the resulting equations and output values:

V1		Operator1		V2	Operator2			V3	Operator3	V4
12		+(M)		6	/(H)			3	-(L)	1
	Equation: (12 + (6 / 3)) - 1 Result: 13
V1		Operator1		V2	Operator2			V3	Operator3	V4
2		+(L)		3		*(M)	1		+(H)	4
	Equation: 2+ (3*( Result: 17			1+4))
V1			Operator1	V2		Operator2	V3		Operator3	V4
100			-(H)	25		/(L)	2		+(M)	1

Equation: (100 – 25) / (2 + 1)

Result: 25

5.5.31 Analog math error detection

Fashion: Classic:

Short Description

The analog math error detection block sets an output if an error has occurred in the referenced analog math function block.

Connection	Description
Input EN	Enable the analog math error detection function block.
Input R	Reset the output
Parameter	Referenced FB: block number of an analog math instruction Error to detect: Zero division, Overflow, or Zero division OR Overflow. Auto Reset: Reset the output when the failure condition clears.
Output AQ	Q is set high if the error to detect occurred in the last execution of the referenced analog math function block.

Parameter Referenced FB

The value for the Referenced FB parameter references the block number of an already-programmed analog math function block.

Description of the function

The analog math error detection block sets the output when the referenced analog math function block has an error. You can program the function to set the output on a zero division error, an overflow error, or when either type of error occurs.

If you select the automatically reset check box, the output is reset prior to the next execution of the function block. If not, the output retains its state until the analog math error detection block is reset with the R parameter.

In any scan cycle, if the referenced analog math function block executes before the analog math error detection function block, the error is detected in the same scan cycle. if the referenced analog math function block executes after the analog math error detection function block, the error is detected in the next scan cycle.

Analog math error detection logic table

In the table below, Error to Detect represents the parameter of the analog math error detection instruction that selects which type of error to detect. Zero represents the zero division bit set by the analog math instruction at the end of its execution: 1 if the error occurred, 0 if not. OF represents the overflow bit set by the analog math instruction: 1 if the error occurred, 0 if not. Zero division OR Overflow represents the logical OR of the zero division bit and the overflow bit of the referenced analog math instruction. Output (Q) represents the output of the analog math error detection function. An “x” indicates that the bit can be either 0 or 1 with no influence on the output.

Error to Detect	zero	of	Output
Zero division	1	X	1
Zero division	0	X	0
Overflow	X	1	1
Overflow	X	0	0
Zero division OR Overflow	1	0	1
Zero division OR Overflow	0	1	1
Zero division OR Overflow	1	1	1
Zero division OR Overflow	0	0	0

If the Referenced Analog Math FB is null, then the output is always 0.

5.5.32 Modbus Read

Short description:

When there is a high level at En, the Modbus Read block will be activated and the xLogic shall communicate with a peripheral device as a master via RS232 or RS485 interface. Furthermore, the output will be switched on when communication is established successfully. Otherwise the output (Q pin) remains “off” which means communication has failed.

A signal at input R resets output Q and disables this block at the same time

Connection	Description
Input En	A high signal at En input will enable “Modbus Read” function block to be activated
Input R	To disable the MODBUS read function and set the output to 0 via the R (Reset) input. Reset has priority over En
Parameter	Slave address: 1 is default . Communication protocol: Modbus(RTU) Communication parameter: baud rate (BPS),Data bits, Stop bits, Parity， Overtime (response time out) Comm Type: RS232,RS485,Ethernet( Communication interface of xLogic ) Data register Index: High Low /Low High Command: 01 Read coils(0x) 02 Read Discrete Input(1x) 03 Read Holding Registers(4x) 04 Read Input Registers(3x) Register start address, count
Output Q	Q is set or reset depending on the communication status. Successful communication , Q=1; Failed communication ,Q=0;

Note:

This function block(com type: Ethernet) can not be used for the Ethernet

CPU(ELC-12DC-DA-R-N) built-in web server, it is only for the old version, if you are using new series Ethernet(hardware version:1), please use the MODBUS READ WRITE block instead.

Get the version number by the software menu Tools-> transfer-> Get PLC version

Note: 1. Data register Index: High Low /Low High

For example, when High Low index was set, one data 0x 00 12 was read and saved to AQ, AQ= 0X0012; however, when Low High index was set, AQ=0x 1200

Regarding Modbus RTU detail, please refer to our Modbus RTU communication protocol file for it.

Description of the function:

In the configuration of our xLogic communication, the xLogic usually serves as a slave via Modbus RTU Protocol, and can communicate with a master directly. That’s to say, any device communicating with xLogic sends command to it, and then its response will be sent out only when the xLogic has received the command, Just as the below figure shows:

However, the “Modbus Read” or “Modbus Write”(next chapter will introduce it) function block would be utilized if xLogic shall be required to play a role of master to communicate with other devices. As the following figure shows:

When you put the “Modbus read” or “Modbus Write” function block in your program and make some configurations, the function that xLogic serves as master will be realized.

The Property in dialog box of “Modbus Read” shows as below figure:

Slave Address: 1 is default
Communication parameters：BPS is baud rate、Stopbits、Databits、Communication type: RS232、RS485 . Actually RS232 or RS485 are just interface of xLogic.
Command, register address and register count

Command	Function description	remark
01	Read one group coil status（00000～0XXXX）	Read Coil Status（output）
02	Fetch one group data of the status of switch input （10000～1XXXX）	Read input Status (input relay)
03	Read data of multi-holding register（40000～4XXXX）	Read Holding Registers(Output register)
04	Read data of input registers (3000～3XXXX)	Read Input Registers

Note: Please use “03” command to read AI/AO of xLogic

Where to save the data read from Slave.

Example: The following we'll take a example that one xLogic (Master) communicate with other xLogic (Slave) via RS485.

Example 1: Get Q1 status of SLAVE1(xLogic) and then save the bit status to F1.

If count was set 4, the Q1,Q2,Q3,Q4 of xLogic (station No.1) will be read and save to F1 to F4

F is bit type flag. It can be used to receive bit data from slave device.

Example 2 : Get AI value from Slave 2(xLogic with station No.2) and save the data to AQ11

The number setting of Q,I,AQ are continuous .AQ12 cannot be set as AQ 12 and should be set AQ 4 as above figure shows.

The following table shows how to set.

Note: this table also can be applied for the configuration of Modbus Write function block.

Where is to save thepre-configurationdata that would be written to Slave. It contains 2 kind ways to pre-configuration. One is auto mode, this data uses the flags in the program, such as FM, AFM, I, Q and AQ. The manual mode is input a fixed value or bit status.

Example 1

Write the I2 bit status of Master xLogic to Slave xLogic with No.1 and control Q1 of Slave via RS485 port. The program of master can be made as follows:

I1of master is used to control the communication .If I1 is high and the communication is established successfully, one alarm message (text message block) will be displayed on LCD. Then the Q1 of slave No.1 will be controlled by I2 of master. If I2 is high, Q1 of slave No.1 would be ON and if I2 is low, Q1 of slave would be OFF.

Note: The Q1 must be free, it means the in the program of Slave No.1, the input pin of Q1 must be not linked to other blocks.

Example 2, manual mode input value

The above configuration is to force Q1, Q2, Q3 of Slave No.1 ON. "" means pre-set the BIT 1 and "" means pre-set the BIT 0 ”Coil 0” is corresponding to the start address ,Here is Q1.

5.5.34 Modbus read write

Short description:

This function block is developed for the new Ethernet PLC which has web server built-in, if you need use the Ethernet as master PLC, so block should be applied into the program.

For the CPU with "-N" type, the hardware version number is 1(built-in webserver type). If your CPU hardware version is not 1 and without webserver built-in, you can still use the modbus read and modbus write block to establish the communication.

You can get the hardware version number by Tools-> transfer-> get PLC version number.

When a high level in En, the Modbus Read Write block will be activated and the x-Messenger could communicate with peripheral as a master via RS232 , RS485 or Ethernet interface you selected, further the output will be switched on when the communication is established successfully. Otherwise the output (Q pin) is keep off it means communication is failed.

A signal at input R resets output Q and disable this block at the same time Note:

If you are using old Ethernet CPU(need deviceManger to configure the modem) without web server built-in and you need use MODBUS through Ethernet port, then you still use MODBUS READ or MODBUS WRITE block. The MODBUS READ WRITE( Ethernet comm type) is only for the new version Ethernet CPU.

Connection	Description
Input En	A high signal at En input will enable “Modbus Write” function block to be activated
Input R	Reset the value read from peripheral and set the output to 0 via the R (Reset) input. Reset has priority over En
Parameter	Slave address: 1 is default .
	Communication protocol: Modbus(RTU), Modbus TCP Communication parameter: baud rate(BPS),Data bits, Stop bits, Parity， Overtime(response timeout) Comm Type: Ethernet, RS232 or RS485( Communication interface of PLC ) Data register Index: High Low /Low High Command: 01 Read coils 02 Read Discrete input 03 Read Holding Registers 04 Read Input Registers 15 Write Multiple Coils 16 Write Multiple Registers Register start address, count.
Output Q	Q is set or reset depending on the communication status. Successful communication , Q=1; Failed communication ,Q=0;

Regarding of the RS232/RS485 comm type, you can refer to the instructions of Modbus read or Modbus Write block. Here only explain how to use the Ethernet comm type.

The Property in dialog box of Modbus Read Write shows as below figure:

The CPU can be worked as client or server when you want to make it as a master. We only need make the TCP/IP connection successfully first, then enable the block, the configured data will be transferred through the Tcp connection.

Option A. Local CPU works as client

If the CPU works as the client, so we need know which server will be connected, so you need select the Remote option (1--8) for the server address. This option is based on the network settings from the menu Tools-> transfer->Web Server Config

You can get the network information by the Read button, and if you changed the information, you need click the "Write" button to download the settings into PLC. And click the "Confirm&Reset" button to active the settings.

In above dialog you can see the Max Clients is 4. And the first remote target server is 192.168.227, port is 5001. so if you enabled the modbus read write block(B013) , the CPU will connect with the TCP server 192.168.0.227, port 5001 and read the coils 0 status then save into the Q1 status.

Option B. Local CPU works as server

Select the Local CPU work as server. Then you need input a target client IP address which will be connected to this local CPU.

If the client 192.168.0.214 is connected to the local CPU, and enable the B002, then the datas will be transferred to the device with IP address 192.168.0.214.

Output AQ	Analog output (manipulated variable) Value range for AQ: 0 to 1,000

Parameter P (number of decimal places)

Only applies for portraying the values from PV, SP, Min. and Max. in a message text.

Timing Diagram

The nature, manner and speed with which the AQ changes depends on the parameters KC and TI. Thus, the course of AQ in the diagram is merely an example. A control action is continuous; therefore the diagram portrays just an extract.

A disturbance causes the PV to drop, as Dir is positioned upwards, AQ increases until PV correspond again to SP.

A disturbance causes the PV to drop, as Dir is positioned upwards, AQ decreases until PV corresponds again to SP.

Dir is coordinated to the basic conduct of a control loop. The direction (dir) cannot be changed during the term of the function. The change in Dir here is shown for the purposes of clarification.

As AQ is set to 0 by means of the input R, PV changes. This is based on the fact that PV increases which on account of Dir = upwards causes AQ to drop.

Description of Function

If the input A/M is set to 0, then the special function issues output AQ with the value that you set with parameter Mq.

If the input A/M is set to 1, then automatic mode commences. As an integral sum the value Mq is adopted, the controller function begins the calculations in accordance with the formulas given in Control and regulate basics. The updated value PV is used to calculate in the formulas.

Updated value PV = (PV * gain) + offset

If the updated value PV = SP, then the special function does not change the value of AQ.

Dir = upwards/+ (timing diagram numbers 1 and 3)

If the updated value PV > SP, then the special function reduces the value of AQ.
If the updated value PV < SP, then the special function increases the value of AQ.

Dir = downwards/- (timing diagram number 2)

If the updated value PV > SP, then the special function increases the value of AQ.
If the updated value PV < SP, then the special function reduces the value of AQ.

With a disturbance, AQ continues to increase / decrease until the updated value PV again corresponds to SP. The speed with which AQ changes depends on the parameters KC and TI. If the input PV exceeds the parameter Max., then the updated value PV is set to the value of Max.. If the PV falls short of the parameter Min., then the updated value PV is set to the value of Min.

If the input R is set to 1, then the AQ output is reset. As long as R is set, the input A/M is disabled.

Sampling Time

The sampling time is fixed at 500 ms.

Parameter sets

In order to simplify the use of the PI controller, the parameters for KC, TI and Dir are already given as sets for the following applications:

Parameter set	Application example	Parameter KC	Parameter TI (s)	Parameter Dir
Temperature fast	Temperature, cooling control of small spaces; small volumes	0,5	30	+
Temperature slow	Heating, ventilation, temperature, cooling control of large spaces; large volumes	1,0	120	+
Pressure 1	Quick pressure change, compressor control	3,0	5	+
Pressure 2	Slow pressure change, differential pressure control (flow controller)	1,2	12	+
Full level 1	Vat and/or reservoir filling without drain	1,0	1	+
Full level 2	Vat and/or reservoir filling with drain	0,7	20	+

Characteristics when configuring

Observe the Control and regulate basics.

Control and regulate

In engineering, quantities can be both controlled and regulated.

When controlling, a quantity is manipulated without being able to compensate for outside influences. When regulating, a quantity is maintained at a specific value in order to compensate for outside influences.

In the following example, controlling means that the person can set the heat output at a fixed value. The heater cannot compensate for the drop in room temperature when a window is opened.

In the example below, regulating means that the person can increase the heat output if the room temperature drops to below 20 °C. If the room temperature rises above 20 °C, the heat output is reduced.

Basic concepts of regulating

In the example, the current for the electric heating is the manipulated variable. The changeable resistance is the actuator. The hand that operates the actuator is the control. The actual room temperature is the controlled variable or the process value. The desired room temperature is the command variable or the setpoint value. The electric heating is the control process. The thermometer is the sensor. The temperature loss from opening the window is the disturbance variable.

So this means that the person measures the process value (room temperature) with the sensor (thermometer), compares the process value (room temperature) with the command variable (desired room temperature) and uses the actuator (changeable resistance) to manually regulate the manipulated variable (heating current), in order to compensate for the disturbance variable (temperature drop from opening the window). The person is therefore the controller.

The control device is formed from the actuator and the control.

The control and controller together form the regulating device.

The following picture gives an abstract portrayal of the situation described above.

The comparing element uses the sensor to compare the command variable with the process value. If the command variables and process value deviate from one another, this results in a positive or negative loop error that in turn changes the process value.

Control loop

The process value x influences the manipulated variable M by means of the regulating device. This creates a closed circuit that is also known as a control loop.

If, in the example above, the window is opened, the temperature in the room drops. The person must increase the heat output of the heater. If the heat output is increased too much, it will get too hot. The person must then reduce the heat output.

If the heat output is increased or reduced too quickly, then the control loop starts to sway. The room temperature fluctuates. It is either too hot or too cold. To prevent this, the person must carefully and slowly reduce or increase the heat output.

Loop error

The loop error is the difference between the command variable and the process value. In other words: the deviation of a process value from a set value.

e = SP – PV

The loop error e brings about a change to the manipulated variable M.

The example above illustrates this very well: if, with a desired temperature of 20 °C (= command value w), the room temperature is 22 °C (= process value PV), this results in the loop error:

e = SP – PV = 20 °C - 22 °C = -2 °C

In this case, the negative sign indicates a reversing action: the heat output is reduced.

In a control loop's state of equilibrium, the loop error is zero or very small. If the command variable changes or there is a disturbance, a loop error arises. The loop error is corrected by means of the manipulated variable M.

Controller basics

A controller can be simply portrayed as follows:

The comparing element and the controller function describe the conduct of the controller.

The following describes the most important types of controller. A controller's step response tells us a lot about its conduct. The step response describes how a controller reacts to the erratic change in the process value.

There are 3 important basic types of controller:

Proportional-action controller (P controller)

Integral-action controller (I controller)

Differential-action controller (D controller – we're not touching on this here) These are combined for a real controller. For instance, the PI controller:

P Controller

A proportional-action controller (P controller) changes the manipulated variable M proportional to the loop error. The P controller works immediately. By itself it cannot drive the loop error to zero.

:Manipulated variable of the P controller at the time n

:Gain of the P controller

: Loop error at the time n

The following picture shows a jump in process value and step response of the controller:

Summary

The P controller has the following characteristics:

It cannot correct faults with the control process > lasting loop error.

It reacts immediately to a change in the process value.

It is stable.

I Controller

An integral-action controller (I controller) changes the manipulated variable M proportional to the loop error and to the time. The I controller works by delayed action. It completely remedies a loop error. In order to calculate the value of the manipulated variable at a period of time n, the time up until this period of time must be divided into small time slices. The loop errors at the end of each time slice must be added up (integrated) and they are then entered in the calculation.

: Manipulated variable of the I controller at the time n

: Manipulated variable of the I controller at the time n-1; also called integral sum

: Gain of the I controller

: Sampling time, duration of a time slice

: Integral time: by means of this time, the influence of the integral part is controlled on the

manipulated variable, also known as integral-action time

: Loop error at the time n

: Loop error at the time n-1; etc.

: Loop error at the beginning of the calculations

The following picture shows a jump in process value and step response of the controller:

Summary

The PI controller has the following characteristics:

It sets the process value exactly to the command variable.

By so doing, it tends to oscillate and is unstable.

It requires more time to carry out the control action than the P controller .

PI controller

A PI controller reduces the loop error immediately and will eventually drive the loop error to zero.

: Manipulated variable at the time n

: Proportional part of the manipulated variable

: Integral part of the manipulated variable

: Manipulated variable of the I controller at the time n-1; also called integral sum

: Gain of the P controller

: Gain of the I controller

: Sampling time, duration of a time slice

: Integral time; by means of this time the influence of the integral part is controlled on the manipulated variable, also known as the integral-action time : Loop error at the time n

The following picture shows a jump in process value and step response of the controller:

Summary

The PI controller has the following characteristics:

The P controller components quickly intercept an occurring loop error.

The I controller components can then remedy the remaining loop error.

The controller components supplement each other so that the PI controller works quickly and precisely.

SP	The parameter SP is the set-value assignment w. For this parameter you can use the analog output of a different special function.	-10,000 to +20,000
PV	PV is the process value x and is calculated as follows: PV = (analog value on input * gain) + offset. You can connect the input for example by means of an analog input with a PT100 sensor.	"
	The gain parameter has an effect on PV	0.0 to 10.0
	The offset parameter has an effect on PV	-10,000 to +20,000
	PV is restricted by the parameters Min. and Max.	In each case: -10,000 to +20,000
	The Dir parameter gives the action direction of the controller. Positive means: If set value > process value then the process value is increased; if set value < process value then the process value is reduced. Negative means: If set value > process value then the process value is reduced; if set value < process value then the process value is increased. e.g. heat regulation: if the set value is greater than the process value (room is too cold), the manipulated variable increases the process value.	- or +

If someone wants to use the upper/lower limitation for other function blocks. function can be used, then this block can be referenced as other blocks parameters when programming.

Here is an example:

Someone wants to use the panel key to change the on-delay parameters for 1s—10s in the text message block, if the value which user set exceeds such range, then it will crush the machine, hence we must add the upper/lower limitation in the program to avoid such trouble.
