Siemens S7 400 ,Allen Bradley Logix 5561 & GE Rx3i Communication

Hi Everybody ,

Please give some idea about to make communication between GE Rx3i CPU320 , Allen Bradley Logix 5581E/Logix 5561 & Siemens S7400 CPU417-4/CPU443-1 .


Thanks in advance

This will depend on what kind of communication you need between the units. If it involves interlocks between the processes then hardwire inputs and outputs between the PLCs. If you need communication that does not need to be deterministic then look for a protocol that is common to all of the controllers.
Modbus TCP looks to be available to all of the controllers.

Hope this helps you out.
