1746-NI8 Class 1. BTW, not sure what the yes was for. do I have to stop the PLC to change configuration on just one of the channels or can it be done online without shutting off the PLC? The configuration of one channel does not seem correct (it shows disabled whereas it whould be enabled), rest are fine... so I was wondering if I could write the correct configuration for that channel online so that I could enable it i.e write a bit 1 in the appropriate place instead of the 0 that it is displaying currently?
