Detected group view
Parameters
and: Specifies the relationship between detected objects as logic AND, which means that the detecting
result is reachable only when all the detected objects contained in the detected group are reachable.
or: Specifies the relationship between detected objects as logic OR, which means that the detecting
result is reachable if one of the detected objects contained in the detected group is reachable.
Description
Use the option command to specify the way to generate detecting results.
Use the undo option command to restore the default way to generate detecting results.
By default, the relationship between the detected objects is and.
When a detecting operation is being carried out, the switch detects each detected object contained in
the detected group in turn by their sequence number.
If you specify the and keyword, the switch returns reachable as the detecting result only if all the
detected objects in the detected group are detected reachable.
If you specify the or keyword, the switch returns reachable as the detecting result only if one of the
detected objects in the detected group is detected reachable and the remaining detected objects
will not be detected any more.
Examples
