1771-IFE data not matching

I have a 1771-IFE/C analog card where the data that is showing in the I/O config is not matching what is the actual register that the data is going too. Any thing I'm missing here? Attached are screenshots of what I am talking about and the BTW and BTR for the card.

I suspect the values are changing faster then your computer screen can pick them up.

Watch them and see if they are bouncing around.

The logic screen shot and the block transfer screen shot are not going to update together.


I would also change the data format to "Two's Complement Binary" ( not causing your issue). And also use 0-4095 for the
min/max scale. Do some math in your logic for scaling to engineering units.

A value of -1025 usually suggests that the signal is 0mA or a faulty channel or card.

Other than that, yes use 0-4095 as you min/max for each channel and change the display.
