After having some trouble with the same issue I now have this setup working. Be careful to ensure the definition matches in both sides for rack/slot and connection resource. Also in the S7-1200, i found by default the SIMATIC-ACC checkbox was checked which i had to disable before i could define a custom connection resource for the S7-1200. See attached for a working setup in terms of hardware/netpro config of both sides. In my program i am using PUT/GET in the S7-400H. I had to call 2 separate GET blocks, one for each connection ID. Only one GET block is called during program execution, determined by which S7-400H CPU is master (Info from SFC51). I found that the GET block did not like a change in the connection ID input parameter so i ended up with 2 GET blocks, identical in parameter apart from connection ID. The same applies for the PUT blocks. AttachmentS7-400H to S7-1200 S7 Connections.pdf (2601 Downloads) |
