Communication / Network
14
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

How to mount a xLogic module and an expansion module onto a DIN rail:
1. Hook the xLogic Basic module onto the rail.
2. Push down the lower end to snap it on. The mounting interlock at the rear must engage.
3. Hook the xLogic expansion module onto the rail
4. Slide the module towards the left until it touches the xLogic CPU.
5. Push down the lower end to snap it on. The mounting interlock at the rear must engage.
6. 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.
25
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:
1. Insert a screwdriver into the eyelet at the bottom of the slide interlock and move the
latch downward.
2. Swing the xLogic Basic off the DIN rail.
....... if you have connected at least one expansion module to xLogic Basic:
1. Remove the connector on the flat cable
2. Slide the expansion module off towards the right.
3. Insert a screwdriver into the eyelet at the bottom of the slide interlock and lever it
downward.
4. 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).

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
31
* AC type digital inputs
* Analog Inputs (DC 0…10V)
*Analog inputs current Inputs (0…20mA)
32
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).

3.4.3 Connecting xLogic Outputs
1. 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:
2. 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.

4.3.4 How to set address of CPU and expansion module
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
52
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..)
53
1. 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:
54
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.

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.
62
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.
63
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.
2. If the arrow keys(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).
64
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.
65
5.2.8 F (digital flag)
1. Keep the input pin of F NULL(do not connect with other blocks) ,if you want to use the write property.
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.
66
5.2.9 AF (Analog flag)
View in the circuit diagram
View in xLogicsoft
Name of the basic function
AND
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.
2. 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.
3. 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:

5.3.9 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.
75
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 parti cular are desc ri bed 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):
76
This input will not be connected. Here, you configure the time patterns.
Time base
_ _ :
_ _
s (seconds)
seconds
:1/100 seconds
m (minutes)
minutes
:
seconds
h (hours)
hours
:
minutes
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:
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
77
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 switchingstates 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.

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 sensorconverts 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

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.
The output is controlled by means of a configurable on/off date. The function supports any combination
of weekdays.
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)
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.
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
99
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:
1. Move the cursor to one of the Cam parameters of the timer (e.g. No1).
2. Press OK. xLogic opens the Cam parameter assignment screen form. The cursor is
positioned on the day of the week.
3. Press and to select one or several days of the week.
4. Press to move the cursor to the first position of the on-time.
5. Set the on-time.
Modify the value at the respective position, using the keys and . Move to the cursor to
the various positions, using the keys and . At the first position, you can only select the
value - -:- -
(- -:- - means: No on-/off-times set).
6. Press to move the cursor to the first position of the off-time.
7. Set the off-time (in same way as in step 5).
8. Confirm your entries with OK.
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.
