Safety FB Common Input Variables
S_AOPD_In
SAFEBOOL TRUE or FALSE
FALSE
A variable. This is the OSSD (safety output) signal from
the AOPD (active optoelectronic protective device).
FALSE: Something entered the protected area.
TRUE: Nothing entered the protected area.
S_MutingSwitch
11
SAFEBOOL TRUE or FALSE
FALSE
A variable. It is the status of muting sensor 11.
FALSE: Muting sensor 11 is not operating.
TRUE: A workpiece activated muting sensor 11.
S_MutingSwitch
12
SAFEBOOL TRUE or FALSE
FALSE
A variable. It is the status of muting sensor 12.
FALSE: Muting sensor 12 is not operating.
TRUE: A workpiece activated muting sensor 12.
S_MutingLamp
SAFEBOOL TRUE or FALSE
FALSE
A constant or a variable. It is the muting lamp status input
(e.g., filament broken status).
FALSE: Muting lamp failure.
TRUE: Muting lamp is normal.
DiscTimeEntry
TIME
T#0s to T#4s
T#0s
A constant. It inputs the maximum discrepancy time
between
MutingSwitch11
and
MutingSwitch12.
MaxMutingTime
TIME
T#0s to T#10min
T#0s
A constant. It inputs the maximum time until completion of
the muting sequence. The timer starts when the muting
sensor first operates.
