PositionMonitoring tags (positioning axis/synchronous axis)
The tag structure <TO>.PositioningMonitoring.<tag name> contains the configuration for
position monitoring at the end of a positioning motion.
If the actual position value at the end of a positioning motion is reached within the tolerance
time and remains in the positioning window for the minimum dwell time, then
<TO>.StatusWord.X5 (Done) is set in the technology data block. This completes a Motion
Control job.
If the tolerance time is exceeded, then technology alarm 541 "Positioning monitoring" with
supplemental value 1: "Target area not reached within the positioning tolerance time" will be
indicated.
If the minimum dwell time is not met, then technology alarm 541 "Positioning monitoring"
with supplemental value 2: "Target area exited within the minimum dwell time" will be
indicated.
