Note
A stop response listed in Table 6-6 "Priorities for stop responses" can only be
initiated if at least one safety--related function is active (except for STOP F).
Once a stop response has occurred, the sequence of operations it involves will be
completed even if the cause of the stop no longer exists.
It is possible to advance to stop responses that have a higher priority. It is not
possible to advance to stop responses that have a lower priority.
When the external stops are selected, there is still the exception that the actual
low--priority STOP F can be initiated in spite of this.
