Note
If the sequence control stops at a particular point because a checkback signal
has not been received, STOP D is triggered after the crosswise data
comparison tolerance time. After the error has been corrected, the error can
be acknowledged with a reset and the particular test stop completed.
If the Emergency Stop button is actuated during test stop step 2, the
sequence control stops at its current position. As soon as the Emergency
Stop is acknowledged, the test phase is completed.
