Muting Function Block Parameters
Set these parameters for the two-hand control function block.
Muting Function Block Optional Outputs
Optional outputs can also be used in programming. To use these optional
outputs, check the appropriate checkbox on the In/Out Setting tab of the
Function Block Properties dialog box in the Logic Editor of RSNetWorx for
DeviceNet software.
• Overriding
• Synchronization error
• Sequence error
• Discrepancy error (AOPD)
• Discrepancy error (Override)

Parameter Settings/Range Default
Muting Mode ·Parallel muting with 2 sensors
This pattern is suitable for applications at a conveyor entrance. Use this pattern when two retro-reflective photoelectric
sensors are set up as muting sensors with intersecting detection zones.
·Sequential muting (forward direction)
This pattern is suitable for applications at a conveyor entrance. Use this pattern when four through-beam photoelectric
sensors are set up as muting sensors.
·Sequential muting (both directions)
This pattern is suitable for applications at a conveyor entrance or exit. Use this pattern when four through-beam
photoelectric sensors are set up as muting sensors.
·Position detection
This pattern is suitable for applications in which muting is controlled by a switch input. Use this pattern to temporarily
disable the light-interruption signal of the light curtain when an operator is placing an object in the machine opening,
and the machine is in a state where it will not harm the operator (hazards are in a different zone of the machine).
In all of these setting explanations, the muting sensors are on when detection is performed and off when detection is not
performed.
