Dear colleagues.

I have CPU 319-3PNDP with CP342-5. The first port of the CPU is working on MPI mode, just to get online with PG/PC, the second one is configured in Profibus DP master mode, and i have a few devicesconfigured on that network, the CP342-5 is a second DP master and it handle other devices (20 nutrunners).

Until now i'm able to get diagnostics from DP master system in the CPU port using FB125. But now my client wants the same kind of diagnostics for the DP master system on the CP, my questions are:

1. Is it posible to use FB125 to get theDP diagnostics of the CP342-5?
2. If it is posible, wich recomendations can you provide me?
3. If not please would you like to tell me, what do recomend to do in this case?

Thanks a lot for your help, and have a very nice day .
