OMRON NS8 HMI communicating to CJ1M scu41 communication module

Hello friends,

Can I seek your expert advise, I am new to Omron HMI/PT interfacing to Omron PLC.
My question is how to communicate this to?

1. If using Port B (HMI/PT) and port 1 of CJ1M scu41 module, what is the correct cable? Can you share the pin-out configuration?
2. I believe I will set the unit number in the CJ1M scu41 module, but how to incorporate the serial communication in CX program? I was confused in addressing it in DM area.

Please enlighten my doubts.'

Thank you very much.

All of your questions are answered in the Omron Manual V083.
