Data communications module for DL405 PLC
All DL405 CPUs offer at least two built-in communication ports (The D4-450 even has four ports).
However, if even more communication ports are needed, additional Data Communication Modules can be added.
The DCM module is primarily used for three purposes:
- Extra general purpose communications port to connect a personal computer, operator interface, etc.
- Network interface to a DirectNET network
- Network interface to a MODBUS RTU protocol
