NC stops NC program run :
The NC uses the following markers to inform the PLC of NC program interrup-
tion and the reason for the interruption:

NN_ChnStopExtern: The program was interrupted because of an external
request (e.g. Stop key).

NN_ChnProgStopped: The program was interrupted because of a program
stop (M0), the end of a block in Single block mode, etc.

NN_ChnProgStoppedAsync: The program interruption was caused by an
error, etc.
