The output of the "AND0" block can be directly assigned a drive order or can be assigned
the prioritized STOP door command via an additional negation block. This corresponds to
enabling for the actual drive order. The following example illustrates this:

2-
hand control device active → STOP is cleared → OPEN becomes active
