Messaging from MicroLogix 1100 to CompactLogix

[firejo 0]

Hey all. I’m trying to message from a MicroLogix 1100 to a CompactLogix. I’ve created the SLC mapping but when I execute the message instruction I get the error: “Error code (in upper byte of MGx:y.22) was returned by Comms module or CIP device”. I’ve never seen that before and I don’t know where to go from there.

We'll most likely need a little more information in order to provide you a response. The following items would help if we knew. 1. Are you placing the message instruction in the Micro or the Compact Logix processor? 2. We'll need to know the IP Addresses of both machines. 3. Can you post at least screenshots of how you configured your message instruction. Copies of the full programs might become necesary, but I can understand that might not be possible.
