Archie, I have a (5069-L306ER) talking Ethernet/IP to a (P2_-550) Using the example in the P2-550 help file section “Ethernet/IP for the Productivity Series” Set the Ethernet/IP Adapter in the P2 just like the example. Added a Generic Ethernet Module in the AB PLC data type as INT. 50 elements. AB 0-49 – P2 1-50. AB writes to output block and reads input block , P2 write to input block and reads output block. Thanks
