Hello,
I've inherited a program controlling a hot water skid and I've had to replace an analog input card (1746-NI8) at slot 5 in the rack. When I enable and configure the card through the channel configuration dialog and accept it, a rung is automatically entered at the top of File 2 copying 8 words from the N7 file to Outputs O:5.0 to O:5.7. I have never seen this happen before, although I presume it's standard stuff. The value in the N7 data words is 3853 (decimal). Can anyone explain what's happening here? Why is it writing to outputs at slot 5, when that is an input card?
