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.

13
*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:
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.
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.
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.
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

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

15
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:
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
