This control is fitted to many different machines. Those with a enclosure do have a door interlock that this control supports. The more common question is how to turn it off.
So you need the parameter and a set of wiring schematics from a VMC to get the input/output locations. The input for the fact that the door is closed, that it has locked, and the output to lock the door.
Is this machine not "grandfathered" and exempt from this requirement? This seems a bit odd.
