You can allso disconnect the profibusnode in the plc program before removing the busconnector. But in general just downloading the fault OB will do the job. Regards, Marcjan

Unfortunatelythere isn't, but as Marcjanalready mentioned, you can avoid aCPU stop and the FAQ below has more on this: Which organization blocks do you have to load into the CPU to ensure that the CPU does not go into the "STOP" status when a remote I/O fails? I hope this helps
