Hi,

I have a problem with a PLC that gose in to fault now and then with a bus fault. The only thing that helps is t repower the ET200m Isle and the PLC. I think the cause may be a short power failure on the ET200M isle.
Now if I use OB86 than the PLC will not go into stop.
My Question is : will the busfault go away when the ET200M is powered again? And will the communication restart then?

Also, you should probably add some logic in OB86 that records exactly which module faulted out. Of course, I'm assuming that you have an HMI that can display this info. If not, then an empty OB86 should suffice.
