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.
