Hi all,
I have a 1769-IF8 Analog Input Card in a Micrologix 1500 system.
The card does not read any inputs. I already checked the wiring and it seems to be OK.

Any ideas?

Thank you in advance!

You have to configure the card prior to getting any readings.

Maybe your card is looking for current and your sensor is sending voltage, or visversa.

I believe the default is for all channels to be disabled, can you post a snapshot of your configuration?

Thank you for your responses!
I think that the card configuration is correct, but I'm posting one of the tabs of the configuration window.
