Issue

After adding a Rockwell CPUs (such as Compactlogix ones) EDS files in the DTM catalog, we can’t “add connections" in order to exchange data between the NOC or SE CPU and those Rockwell CPU.

BMENOC, M580

This is an EDS file of a Rockwell CPU (Micrologix in this case) in Note pad:

This clearly shows no communication parameters and connections available. We can notice the difference with the EDS file for a connexium switch for example.
Therefore, there is no way to add a connection to that EDS file; this means that this Micrologix controller doesn't support implicit messaging.

We then recommend to use explicit messaging via the DATA_EXCH block
