Note:
If several faults occur consecutively, then this message is only signaled for the 󹪝rst fault that occurs.
Remedy: - Check the wiring of the F-DI (contact problems).
- If t
he wiring is correct, and for example there is no wire breakage, then a check must be made as to whether the switching
frequency at F-DI is too high and must therefore be reduced (switching pulses must have a longer time between them). The
time interval between each signal edge at an F-DI must be at least equal to the discrepancy time before the input is switched
again.
Note:
This message can be acknowledged via F-DI (safe acknowledgment).
Discrepancy errors of an F-DI can only be acknowledged if safe acknowledgment was carried out after the cause of the error
was resolved (extended message acknowledgment, self acknowledgment). As long as safety acknowledgment was not
carried out, the corresponding F-DI stays in the safe state internally.
A self acknowledgment for an F-DI can be realized using a positive edge at the corresponding F-DI.
Sets the discrepancy time for fast switching operations at the F-DIs:
For fast switching operations at the failsafe digital inputs (F-DI), it may be necessary to adapt the discrepancy time to the
switching frequency:
- The period of a cyclic switching pulse must be less than half of the discrepancy time (if necessary, round down).
- The time between two fast switching pulses should be longer than the discrepancy time (if necessary, round up).
- The discrepancy time must be greater or equal to the SI monitoring clock cycle (it must always be rounded up or down to
be an integer multiple of the SI monitoring clock cycle).
If an input 󹪝lter has been parameterized (p10017 > 0), then the shortest possible discrepancy time is directly speci󹪝ed by
the input 󹪝lter.
- The period of a cyclic switching pulse must be less than half of the discrepancy time p10017 (if necessary, round down).
- The time between two fast switching pulses should be longer than the discrepancy time+p10017 (if necessary, round up).
- The discrepancy time must be greater or equal to the SI monitoring clock cycle. The input 󹪝lter must always be set less than
the discrepancy time.
Self test with speci󹪝ed dark pulses (p10041 > 0) for long cable lengths:
- Increase the dark pulse length (p10018 or p10019).
- Increase the input 󹪝lter (p10017).
