Digital Electronics Module 4 Do - Siemens SIMATIC ET 200iSP Operating Instructions Manual

input signal is fixed at "zero" and the value status is "invalid" because this channel is only used
for a validity check of the sensor.
Note the following points when carrying out a diagnosis for a changeover contact sensor type:
● If there is already an error on the normally open contact channel (a wire break, for example),
the module no longer performs diagnostics for changeover contact errors. The diagnostics
for changeover contact errors continues on the second channel.
● You will find additional points to note in the following table:

A negative check means...
● Short-circuit or
● Wirebreak
● Sensor defective or short-circuit
No distinction can be made here between a defective-sensor
and short circuit
Caution: no differentiation possible between
● signal "0" and wire break
● Signal "1" and short circuit
