After test stop step 1 has been completed, the external STOPs are tested.
The test sequence is implemented by a simple sequence control in which the
external STOPs D, C, A are triggered one after the other in the PLC and then in
the same sequence in the NCK. The STOPs are checked by reading back the
safe output signals "STOP D, C, A active" into the PLC.
The sequence does not wait for the individual stops to be de-selected
before the next stop is tested. This is because the external stop with a
higher priority de-activates the external stop with a lower priority!
