I have four Generators Sets that I will like to comunicate with my PLC Allen Bradley Micrologix 1100 using MODBUS RTU Protocol.

The problem is that 2 of them use RS-485 (Two Wires) and the other 2 use RS-422 (Four Wires) all MODBUS RTU.

There is any way that I can Incorporate all to my networks in the PLC using RS-485 MODBUS?
