582 Status Variables
In the Tag Explorer, select both Axis System Variables and the desired
physical or imaginary axis, then select PCAM_auto_correction_status in
the Tag Window.
Auto-correction is enabled and disabled in the Configure Cam block.
Auto-correction on an axis is automatically disabled when the position-
lock cam, of which the axis is a slave, is stopped.
Watch Position Status
Watch_Pos_status is a logical (Boolean) variable which has values of:
• 0 (false) after a watch position event has been set up and before the
watch position event occurs
• 1 (true) after the watch position event occurs
In the Tag Explorer, select both Axis System Variables and the desired
physical or imaginary axis, then select Watch_Pos_status in the Tag
Window.
The Watch_Pos_status variable indicates whether the watch position
event—previously set up for the axis—has occurred.
Important: Until the watch position event is set up, the
Watch_Pos_status variable value is undefined.
