Trying to use the M580 to read directly to an Allen Bradley rack via a 1756-EN2T card. Setup the DTM in the browser and configured the rack and cards in Control Expert V15. When built the program does not give any structure to read or write to. I am able to connect to the EN2T though the DTM browser but no data can be loaded. There is no AB PLC in the rack just the EN2T card. Schneider CPU is P58 4030.
Is this possible or is an AB PLC required to actually use the AB IO?
Thank you,

Are some link options for data exchange between CPUs, however for AB IO this is unique for Rockwell PLCs and the exchange of data is not something the M580 can replicate.
