Fig. 107: Timing diagram for SF_MutingPar_2Sensor (S_StartReset = TRUE, Reset = FALSE,
S_MutingLamp = TRUE)
The FB detects the following error conditions:
●
DiscTimeEntry has been set to value less than T#0s or greater than T#4s.
●
MaxMutingTime has been set to a value less than T#0s or greater than T#10min.
●
The discrepancy time for the S_MutingSwitch11/S_MutingSwitch12 sensor pair has been
exceeded.
●
The muting function (S_MutingActive = TRUE) exceeds the maximum muting time
MaxMutingTime.
●
Muting sensors S_MutingSwitch11, S_MutingSwitch12 are activated in the wrong order.
●
Muting sequence starts without being enabled by MutingEnable.
●
Static muting sensor signals.
●
A faulty muting lamp is indicated by S_MutingLamp = FALSE.
●
A static Reset condition is detected in state 8001 and 8003.
Error behavior
In the event of an error, the S_AOPD_Out and S_MutingActive outputs are set to FALSE. The
DiagCode output indicates the relevant error code and the Error output is set to TRUE.
A restart is inhibited until the error conditions are cleared and the safe state is acknowledged
with Reset by the operator.
