3.4.3 Short circuit in sensor supply at an input module

Festo P.BE-CP-FB5-E-EN en 0112a
If there is a short circuit or overload:
– the sensor supply to all the inputs of a module will be
switched off,
– the green LED "Diag" on the input module will flash
quickly,
– the error bit in the diagnostic byte will be set to logic "1"
(SC/O).
Please note
The inputs cannot be used again until the short circuit or
overload is eliminated and the fault is deleted.
Deleting faults
You can delete the fault in one of the following ways:
S
briefly interrupt the CP connection at the CP input module
or
S
briefly interrupt the operating voltage of the CP system at
the field bus node
The inputs can then be interrogated again. If the short circuit/
overload still exists, the error will be displayed again.
