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 acknowledgment was carried out (see p10006). As long as safety acknowledgment 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
Example:
If the SI sampling cycle is 12 ms and the switching frequency is 110 ms (p10017 = 0), the maximum discrepancy time
which can be set is as follows:
p10002 <= 110/2 ms - 12 ms = 43 ms --> rounded-off, the following is obtained p10002 <= 36 ms
Since the discrepancy time can only be accepted as a whole SI sampling time, the value will need to be rounded up
or down to a whole SI sampling time value if it is not an exact integer multiple of an SI sampling time.
Basic secondary condition to set the discrepancy time:
The discrepancy time of the FDIs must always be set higher than the highest value p9780 (the drives that use safety
with TM54F).
F-DI: Failsafe Digital Input
F-DO: Failsafe Digital Output
F35152 TM54F: Internal software error
Message value: %1
Message class: Hardware/software error (1)
Drive object: B_INF, TM54F_MA, TM54F_SL, VECTOR_G
Component: Terminal Module (TM) Propagation: GLOBAL
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: An internal software error has occurred in the Terminal Module 54F (TM54F).
The fail-safe digital inputs and digital outputs (F-DI, F-DO) on the TM54F have been set to the safe state.
Fault value (r0949, interpret decimal):
Only for internal Siemens troubleshooting.
