Sensor Supply At An Input Module - Festo CPV..-DI01 series Electronic Manual

3. Diagnosis PROFIBUS−DP

3.6.2 Sensor supply at an input module

3−26
If there is a short circuit, overload or voltage fault in the
sensor supply:
the sensor supply for all inputs of the module will be
switched off.
the green LED Diag" on the input module will flash
quickly.
the fault bit V
sen
will be set to logical 1.
Please note
The outputs cannot be used again until the short circuit or
overload has been eliminated and the fault deleted.
Deleting the fault
You can delete the fault in one of the following ways:
Briefly interrupt the CP connection at the CP input module
or
Briefly interrupt the operating voltage of the CP system on
the CPV Direct
The inputs can then be scanned again. If the short circuit/
overload still exists, the fault will be shown again.
Module CP−E16−M8−Z:
The short circuit/overload will be reset automatically and the
voltage will be switched on again.
