Hi PMCR, we are trying to Change from CJ1M to CJ2M (with EIP) and get this omron plc set to communicate with one set of AB Micrologix (through Ethernet/IP).

Please guide me as we need to know further on below:

 

1. Possible of conversion from CJ1M-CPU23 (Slot 0 to Slot 9 occupied) into CJ2M-CPU3x?

2. Shall use Explicit or Implicit type of communication within CJ2M and micrologix?

Thanks in advance.

Robin
