n Job start in each PLCopen-State possible.
The reading of the axis parameter data is started with an edge 0-1 at Execute. Busy is
TRUE as soon as reading of parameter data is running. After the parameter data was
read, Busy with FALSE and Done with TRUE is returned. The output Value shows the
value of the parameter.
An active job continues to run even when Execute is set to FALSE.
