Programming
7.5 Tracking active jobs
The behavior of the parameters is presented by way of example for various situations:
Complete execution of job
If the Motion Control job has been fully processed to the point of completion, then this is
indicated in the "Done" parameter with the value TRUE. The signal status of the "Execute"
parameter influences the indication duration in the "Done" parameter:
You set "Execute" after completion of the job to FALSE.
①
The job is started with a positive edge at the "Execute" parameter. Depending on the program, "Execute" can be reset
to the FALSE value while the job is still busy, or retain the TRUE value until the job has been completed.
②
While the job is active, the "Busy" parameter shows the value TRUE.
③
When the job is complete (for example, for Motion Control instruction "MC_MoveAbsolute": target position reached)
the "Busy" parameter changes to FALSE, and the "Done" parameter to TRUE.
④
As long as the "Execute" parameter retains the value TRUE after completion of the job, the "Done" parameter also
retains the value TRUE.
⑤
If the "Execute" parameter has been set to FALSE before the job is complete, then the "Done" parameter only shows
the value TRUE for one execution cycle.
186
You set "Execute" during processing of the job to FALSE.
