Processor Communication Channels Addressing
(Original Document)
About us
At a Glance
Following are examples of the different types of addressing for a processor’s communication channels.
The examples are based on a Modicon M340 type processor.
The modules have a topological address that is a function of the module’s position in the rack.
The first two slots of the rack (marked PS and 00) are reserved for the rack’s power supply module (BMX CPS ••••) and the processor (BMX P34 •••••) respectively.
Available communication channels
The available communication channels vary depending on the processor:
Processor
Integrated Modbus Connection
Integrated CANopen Master Connection
Integrated Ethernet Connection
