*) This setting is not applicable with passive-type analog sensors (current).
The function of the LEDs is described under Diagnosis and displays / displays
1.6.2.2.3.7 "Diagnosis" on page 475.
Unused input channels can be left open, because they are of low resistance.
Connection of digital signal sources at analog inputs
Several (or all) analog inputs can be configured as digital inputs. The inputs are not galvanically
isolated against the other analog channels.

If series-connection of an additional input is used, the input resistance of the
module (ca. 330 Ω) must be added to the input resistance of the second device.
Make sure that the maximum permitted load resistance of the analog sensor is
not exceeded (see the data sheet of the analog sensor).
The input of the module is not related to ZP. If the input of the second device is
related to ZP, the order of sequence in the series-connection must be observed
by all means (from the sensor to the module and then to the input of the second
device).
