I am getting max counts on my analog input 32640 on a temperatur transmitter. I have a compactlogix L24ER and I added a 1769-IF4XOF2 in slot 2 (only additional module). I have used an SCL to scale the analog data but it only reads max value. I didn't realize there seems to be a few more steps with this combo analog/in/out card. I looked up the manual and set the control bits enable-in to 1 (0-3) downloaded and rebooted PLC but still don't have a valid reading. I have a local display that shows the PV output. I must be missing something.
