CAUTION!
The earthing potential at the sensors must not have a too big potential differ-
ence with respect to ZP (max. ±1 V within the full signal range). Otherwise prob-
lems can occur concerning the common-mode input voltages of the involved
analog inputs.

In order to avoid error messages or long processing times, it is useful to configure unused
analog input channels as "unused".
Use of Analog Inputs as Digital Inputs
Several (or all) analog inputs can be configured as digital inputs The inputs are not electrically
isolated against the other analog channels.
