Hello :
please could you help me?:
I have PROFIBUS Mono System Network(One Master(CPU313C-2Dp) & Tow Slave's(CPU313C-2Dp))when any Slave go out from the service ,the Master goes to Stop Mode and the second slave still in RUN Mode.
but I want to keep the Master in RUN Mode too.
What can I do?
 
Hint: Look in the diagnostic buffer why the CPU goes to stop mode.

Spoiler: It is probably OB86 that is needed. Typically you add OB82, OB85, OB86 and OB122 to avoid the CPU to go to stop mode due to hardware errors.
