Example for
SF_MutingPar_2
Sensor with two
reflecting light
barriers
Fig. 106: Example for SF_MutingPar_2Sensor
If reflection light barriers are used as muting sensors, they are generally arranged diagonally. In
general, this arrangement of reflection light barriers as muting sensors requires only two light
barriers, and only S_MutingSwitch11 (MS_11) and S_MutingSwitch12 (MS_12) are allocated.
Muting condi-
Muting condition 1 (to state 8011) (MS_11 is the first actuated entry switch). Start timer DiscTi-
tions
meEntry and MaxMutingTime:
MutingEnable AND R_TRIG at MS_11 AND NOT MS_12
Muting condition 2 (to state 8311) (MS_12 is the first actuated entry switch). Start timer DiscTi-
meEntry and MaxMutingTime:
MutingEnable AND NOT MS_11 AND R_TRIG at MS_12
Muting condition 3 (from state 8011 to state 8012) (MS_12 is the second actuated entry switch):
Stop timer DiscTimeEntry:
MutingEnable AND MS_11 AND R_TRIG at MS_12
Muting condition 4 (from state 8311 to state 8012) (MS_11 is the second actuated entry switch):
Stop timer DiscTimeEntry:
MutingEnable AND R_TRIG at MS_11 AND MS_12
Muting condition 5 (from state 8000 to state 8012) (both switches actuated in same cycle): Start
Timer MaxMutingTime:
MutingEnable AND R_TRIG at MS_11 AND R_TRIG at MS_12
Muting condition 6 (from state 8012 to state 8000) (both switches released in same cycle or
MS_11 and MS_12 released consecutively). Stop timer MaxMutingTime: NOT MS_11 OR NOT
MS_12
Wrong muting
State 8000 - (R_TRIG at MS_11 AND MS_12 AND NOT R_TRIG at MS_12) OR

State 8011 - NOT MutingEnable OR NOT MS_11
State 8311 - NOT MutingEnable OR NOT MS_12
State 8012 - all possible transitions allowed
