The following always applies:
- check the electrical cabinet design and cable routing for EMC compliance
- upgrade the software on the TM54F.
- contact the Hotline.
- replace the TM54F.
F35151 TM54F: Discrepancy error
Message value: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: B_INF, TM54F_MA, TM54F_SL, VECTOR_G
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The safety input terminals or output terminals show a different state longer than that parameterized in p10002.
Fault value (r0949, interpret hexadecimal):
yyyyxxxx hex
xxxx: The safety-relevant input terminals F-DI indicate a discrepancy.
Bit 0: Discrepancy for F-DI 0
...
Bit 9: Discrepancy for F-DI 9
yyyy: The safety-relevant output terminals F-DO indicate a discrepancy.
Bit 0: Discrepancy for F-DO 0
...
Bit 3: Discrepancy for F-DO 3
Note:
If several discrepancy errors occur consecutively, then this fault is only signaled for the first error that occurs.
The following options are available to analyze all of the discrepancy errors:
- Using the commissioning software, evaluate the input states and output states of the TM54F. All discrepancy errors
are displayed here.
- Compare parameters p10051 and p10052 from the TM54F master and TM54F slave for discrepancy.
Remedy: Check the wiring of the corresponding F-DI (contact problems).
Discrepancy errors in the fail-safe digital inputs (F-DI) can only be completely acknowledged if, after the cause of the
error was resolved, safe acknowledgement was carried out (see p10006). As long as safety acknowledgement was
not carried out, the corresponding F-DI stays in the safe state internally.
Sets the discrepancy time for cyclic switching operations at the F-DIs:
For cyclic switching operations at the fail-safe digital inputs (F-DI), it may be necessary to adapt the discrepancy time
to the switching frequency:
If the period of a cyclic switching pulse corresponds to twice the value of p10002, then the following formulas should
be checked:
- p10002 < (tp / 2) - td (discrepancy time must be less than half the period minus the actual discrepancy time)
- p10002 >= p10000 (discrepancy time must be no less than p10000)
- p10002 > td (discrepancy time must be greater than the switch discrepancy time which may actually apply)
td: possible actual discrepancy time (in ms) that can occur with a switching operation. This must correspond to at
least 1 SI sampling cycle (see p10000).
tp: period for a switching operation in ms.
For cyclic switching operations and when debounce (p10017) is active, the discrepancy time is directly specified by
the debounce time.
If the period of a cyclic switching pulse corresponds to twice the debounce time, then the following formulas should
be checked.
- p10002 < p10017 + 1ms - td
- p10002 > td
- p10002 >= p10000
