Hello Deimus

I must admit it is a very interesting question that you raise here.
It should in theory be quite simple to determine if someone has gone online in the CPU, as all you would have to do is to check if a (or another) PG connection resource is being occupied.
Since PG connectionsare also listed and shown in the CPU's module information, one would assume that you could read out this info in your S7 program (and then react to it whichever way you intend to in your program).
SFC51 is usually the block of choice to read out all sort of system status related things, problem is that the info that you are after does not seem to be provided by SFC51 (I at least can find a suitable SSL-IDfor it).
I'm afraid to say that I can't think of any other possible way, but would love to hear from anyone who has a clever idea to achieve what you are trying to achieve.

New question published by Ales.Valentincic is split to a separate thread with the subject Connect 2 CPU 315 DP with PC via MPI, "The network contains SEVERAL Independent rungs".
