The Muting function block temporarily disables the light-interruption signal
(AOPD input) in a light curtain while the muting sensor is being triggered.
While the muting function is operating, machine operation is not stopped, so an
object can be removed from the light curtain’s detection zone. In addition, the
Muting function block has an override function that can disable the light-
interruption signal of the light curtain and cause the machine to operate while
the light of the light curtain is obstructed. For example, when an object has
stopped in the light curtain’s detection zone, the machine can be operated in
order to remove the object.
