An external STOP E in contrast to the other external stops, results in Alarm
27020, which can only be acknowledged with a reset. The program cannot be
directly continued, since retraction from the desired contour was executed by
the configured ESR. The reset required must also be considered during the test
stop sequence.

The signal must be used for the forced checking procedure for external STOPs.
