Has anyone else experienced a problem of an S7 300 series PLC both stopping and losing its entire config. when an MPI cable is connected.
It happened to me twice recently, fortunately no serious damage was incurred as a result of the PLC crashes.
While on the first occurrence, I concluded a static discharge was probably the cause, the second occurrence with intense precautions suggests this was NOT the cause.
At this point, the only thing I can come up with is that the initial current draw of the adapter caused the PLC to crash.
Has anyone else experienced a similar event?
TIA, Tom
