This occurred on three different FP-1601s networked together via HUB. The modules seem to work and are recognized via LabView DSC. Trying to determine the cause. Could it be data collissions?
This could be the result of a bad FP refnum. I have seen this a lot. In addition you may check your iak file. sometimes the channel names on the head unit get renamed from channel to input. either the led or switches. GL
