‘Extras’ ‘Time Overview’

With this command you can open a window in which you can edit the time settings of your SFC steps:

In the time boundaries overview, all steps of your SFC POU are displayed. If you have ‘Extras’ ‘Step Attributes’ a time boundary for a step, then the time boundary is displayed to the right of the step (first, the lower limit, then the upper limit). You can also edit the time boundaries. To do so, click on the desired step in the overview. The name of the step is then shown below in the window. Go to the ‘Minimum Time’ or ‘Maximum Time’ field, and enter the desired time boundary there. If you close the window with OK, then all of the changes will be stored.

In the example, steps 2 and 6 have a time boundary. Shift1 lasts at least two, and at most, ten seconds. Shift2 lasts at least seven, and at most, eight seconds.
