; -------------------------------------------------------
; System variable $P_PROG_EVENT can be used to
; interrogate as to which event activated the call:

N100 PROC PROG_EVENT SBLOF DISPLOF

; NCK-SPL start

N200 IF ($P_PROG_EVENT == 4); interrogate run-up
N300
N400 ENDIF
N500 ...
N600 ...
N700 M17 ; end of cycle
The part program SAFE.SPF is called if the system variable check
$P_PROG_EVENT indicated that the part program PROG_EVENT.SPF was
called when the control system ran-up.
Example for SAFE.SPF A simple example for SAFE.SPF will now be shown that is started via
PROG_EVENT when the system runs-up and includes status synchronous
actions.
