FW version int is V4.3.1, created with V4.5.1 according to the upload from the CU. GSD file is V4.3. I get comms when I only have one telegram configured in TIA, but at soon as I put in the rest to match the configured telegrams, I lose comms. CU module number is 6SL3 040-1MA00-0xxx. Should there be gaps in between telegrams like in Step7 where Starter was used? Kind regards Rudi
