Flexible NC programming
1.13 Program coordination (INIT, START, WAITM, WAITMC, WAITE, SETM, CLEARM)
Example:
INIT(2,"/_N_WKS_DIR/_DRESS_MPF")
G01F0.1
START
INIT
(2,"/_N_WKS_DIR/_N_UNDER_1_SPF")
● Relative path specification
Example:
INIT(2,"DRESS")
INIT(3,"UNDER_1_SPF")
Parameters
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.
INIT(n, path name, acknowledgement
mode)
START (n, n)
WAITM (marker no., n, n, ...)
118
Up to SW 3:
At least one executable block must be
programmed between an init command
(without synchronization) and an NC start.
With subprogram calls "_SPF" must be added
to the path.
The same rules apply to relative path definition
as for program calls.
With subprogram calls "_SPF" must be added
to the program name.
Instruction for execution in a channel.
Selection of a particular program with an
absolute or relative path name.
Starts the selected programs in the other
channels.
n,n: Enumeration of the channel numbers:
value depends on control configuration
Sets the marker "marker no." in the same
channel. Terminate previous block with
exact stop. Waits for the markers with the
same "marker no." in the specified channels
"n" (current channel does not have to be
specified). Marker is deleted after
synchronization.
10 markers can be set per channel
simultaneously.
