Use of Analog Inputs as Digital InputsΒΆ

Several (or all) analog inputs can be configured as digital inputs CI592-CS31 - Digital and Analog Inputs and Outputs . The inputs are not electrically isolated against the other analog channels.

The following figure shows the connection of digital sensors to the analog input AI0. Proceed with the analog inputs AI1 to AI3 in the same way.
