Fig. 2−68 Configuration for triggering the various fault types
Note!
Each FB instance may only be called once! If you need the FB L_FWM several times, create the
corresponding number of FB instances.
·
If the program includes several instances of the FB L_FWM which are of the same fault type,
then only the first fault of this fault type that is detected will be recorded.
·
If several faults with a different response occur at the same time, only the fault whose
response has the highest priority will be recorded in the history buffer:
– TRIP (highest priority)
® message ® FAIL−QSP ® warning (lowest priority).
·
Only edit L_FWM() in a task.
·
If byTypeOfFault has an invalid value, then the value 0 (TRIP) is used for byTypeOfFault.
·
If the value of wFaultNumber < 400, then the value 400 is used for wFaultNumber, if
wFaultNumber > 999, then the value 999 is used for wFaultNumber.
·
If a fault occurs, it can be read out by using the system variable DCTRL_wFaultNumber.
