Hi all, I have a similar problem. My PLC (S7-1500) is communicating with several Interface modules (IM 155-6 PN/2 HF). On two of them, I am using a CM PtP module as a master. One of them is working just fine and I am reading out a couple of sensors without any problem but with the other one (which I've added on a later stage) I am seeing the same effect - no reading and error 80C8. First of all, is it possible to use several master CM PtP modules as master across the system? Please find attached a screenshot of the two IM 155-6 PN/2 HF sets.
