SF_MutingPar
8422 33826 Muting Backward Start
2
A backward muting sequence is being started
after MutingSwitch22 changed to TRUE. Moni-
toring is active for DiscTime21_22. Monitoring is
active for MaxMutingTime.
Ready = TRUE
S_AOPD_Out = TRUE
S_MutingActive = FALSE
Error = FALSE
8121 33057 Muting Backward
Active 1
A backward muting sequence is in operation for
one of the following.
• A change to TRUE was detected in the sec-
ond muting switch of MutingSwitch21 and
MutingSwitch22.
•Both MutingSwitch21 and MutingSwitch22
were started in the same cycle.
Monitoring for DiscTime21_22 was stopped.
Monitoring for MaxMutingTime is started after a
transition directly from state 8000.
Ready = TRUE
S_AOPD_Out = TRUE
S_MutingActive = TRUE
Error = FALSE
8114 33044 Muting Backward Step
1
A backward muting sequence is in operation.
MutingSwitch11 operates as the first muting
stop switch. Monitoring for DiscTime11_12 is
started.
Ready = TRUE
S_AOPD_Out = TRUE
S_MutingActive = TRUE
Error = FALSE
8414 33812 Muting Backward Step
2
A backward muting sequence is in operation.
MutingSwitch12 operates as the first muting
stop switch. Monitoring for DiscTime11_12 is
started.
Ready = TRUE
S_AOPD_Out = TRUE
S_MutingActive = TRUE
Error = FALSE
8112 33042 Muting Backward
Active 2
A backward muting sequence is still in opera-
tion. Both MutingSwitch11 and MutingSwitch12
are active, so monitoring for DiscTime11_12
was stopped.
