CJ1M to CompactLogix over ethernet

[bks 0]

Hello,

I was hoping for some help in trying to read/write to a handful of bits in a CJ1M-CPU13 controller from a Compact GuardLogix. The CJ1M rack has a CJ1W-ETN21 card that is already communicating to a handful of Yaskawa drives. Is it possible for me to communicate with this controller from a CLX unit over ethernet? I don't believe an ETN21 card uses EIP but is there a way around this?

Right now, I'm struggling to even find the IP address of the ETN21 card as the CX-Programmer file provided to me by the customer does not have the card in the IO configuration and I've never worked with Omron PLCs before. I found a CJ2M to CLX guide but it assumes communication over Ethernet IP and the ethernet port is native to the controller.

Any help at all would be appreciated. Thanks!

You could add a CJ1W-EIP21 (Ethernet/IP module) to the PLC to communicate to the GuardLogix over EIP.  The guide that you have would be similar for using the EIP21 module.
