Watch Control 317
If you did not select Wait for Tripped, the Watch Control block with Arm
and Registration selected sets up the registration event, and the program
continues with the subsequent blocks while the registration event is
monitored in the background.
Auto Rearm Input
When you select Auto Rearm Input, the registration event is
automatically re-configured as specified in the Watch Control block with
Arm and Registration selected, whenever a registration event occurs on
the selected axis. This auto-registration is equivalent to—but much faster
than—the following GML blocks executing in one task, while the latched
registration position is used in another task. With Auto Rearm Input
selected, Registration_status changes from 0 to 1 when the first
registration event occurs and it stays at that value thereafter.
Registration on Virtual Axes
AxisLink virtual axes are functionally equivalent to physical master only
axes therefore, you can also use them for registration events. However,
the registration input of the associated physical axis (on another motion
controller or ALEC) is actually used to generate the registration event.

ATTENTION: You must enable Auto Rearm Input for
any axis that is selected as a registering axis in an auto
correction position-lock cam configuration.
