Note!
When position-time cams are used, overlapping switch-on states of subsequent cams
can occur if the operating time of the position-time cams is longer than the interval to
the switch-on position of the following position-time cams (post-trigger function).
If the operating time of a position-time cam is longer than the total cycle time, the out-
put bOut remains on TRUE permanently.
