Omron CS/CJ Ethernet/Modbus network setup Question

Omron CS/CJ Ethernet/Modbus network setup Question

Omron CS/CJ Ethernet/Modbus network setup Question

(OP)
Hi,
I am very new to Omron PLC's and new enough to PLCs in general and too old for it all!
I have to set up a network with 2xCS+1xCJ PLCs
Each of the CSs have ETN21(ethernet) cards and SCB41(2 Ports: RS232C and RS422) cards fitted
The CJ has only the SCU41(2 ports: RS232C and RS422)
All PLCs will have VSDs talking on Memobus (Yaskawa drives)
The CJ will talk to one of the CSs on radio (Modbus)and the 2 CSs are linked via ethernet (possibly on optic fibre)All 3 will have an NS10 HMI attached (on the Peripheral port??) Can anyone help with how I set up the comms links and how to get data transferred around the PLCS. I'm using the manuals as a pillow (if I get any sleep at all)
