Example of program from workpiece
N10 INIT(2,"/_N_WCS_DIR/_N_SHAFT1_WPD/_N_STOKREM1_MPF")
Example of Init command with relative path definition
;Program /_N_MPF_DIR/_N_MAIN_MPF is selected in channel 1
N10 INIT(2,"MYPROG") ; select program /_N_MPF_DIR/_N_MYPROG_MPF in
channel 2.
Additional notes
Variables which all channels can access (NCK-
specific global variables) can be used for data
exchange between programs. Otherwise separate
programs must be written for each channel.
SW 3 and lower:
WAITE must not be scanned immediately after the
START command or else a program end will be
detected before the program is started.
Remedy: Programming a dwell time.
