Understand a Programming example

This figure shows rungs to redefine the axis position of a motion control application program using the Motion Arm Watch (MAW) instruction.
Watch Position Example
This example shows the ladder logic to:
  • Create a watch position event
  • Enable an output when the trigger condition occurs.
Rung 0:
This rung arms a watch position event for Axis_1 when the arm_ watch bit transitions from false to true
When the MAW instruction begins executing, the Axis_1.WatchEvStatus bit resets. This bit sets when the actual position of 500 in the forward direction.
Rung 1:
This rung enables the cut output when the watch position occurs. (The MAW_1.PC bit sets when the watch position occurs.)
Understand program example_v31
The Motion Disarm Watch (MDW) instruction is used to disarm watch position event checking for the specified axis.
