I have project based on processor CPU 317-2 DP, 512 with Profibus network connected to the processor. Is it possible to simulate profibus network events (communication problems etc.) in S7-PlcSim?

You can simulate a rack failure by triggering OB86 in PLCSIM.
Insert OB86 in your program and write codes to detect which
slave is missing.

Introduction
You can use S7-PLCSIM to test how your program handles different interrupt OBs.
Requirement
To be able to simulate error OBs, you must have downloaded an appropriate hardware
configuration in the S7-PLCSIM.
Procedure
To trigger error OBs, proceed as follows:
1. Choose the menu command Execute > Trigger Error OB
2. Select a specific OB.
The dialog for the OB is opened.
3. Select the corresponding options.
4. Confirm with "OK" or "Trigger" .
