I want to add 2 Siemens S7-300 slaves to an existing Hima network (with Honeywell EPLCG as PLC/TDC-master)
But when I connect the Siemens, my CRCs become bad and the Siemens slaves have serious com problems. Sometimes one becomes ok, but not long.
Has anyone experienced this before? Are there solutions to connect these slaves on RS485-level?
Thanks.
