What would be the RSLOGIX code to communicate peer to peer between two Micrologix 1200's w/1761 NET ENI series B?

I would think that a pair of MSG reads would be the most efficient way to amve a block of data back and forth between them.

We at mrplc generally do not write code for people, but will review, critique and help with any partial attempt you ahve madse first.

Just MSG instructions. But you may have to program the TCP/IP addresses into them so that the NET-ENI's simulate a "node address" similar to using the DF-1 protocol that they are encapsulating. As far as I know, the Micrologix 1200 by itself is oblivious to the concept of an IP address so you have to set the IP addresses in the NET ENI module. Read the NET ENI manual first because it will explain how to do this. The Micrologix 1200 manual won't help you in this situation very much.

Thanks, I will try it.
