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, ...)
WAITMC (marker no., n, n, ...)
WAITE (n, n, ...)
SETM (marker no., marker no., ...)
CLEARM (marker no., marker no., ...)
n
Note
All the above commands must be programmed in separate blocks.
The number of markers depends on the CPU used.

1.13 Program coordination
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.
Sets the marker "marker no." in the same
channel. An exact stop is initiated only if
the other channels have not yet reached the
marker. Waits for the marker with the same
"marker No." in the specified channels "n"
(current channel does not have to be
specified). As soon as marker "marker no."
in the specified channels is reached,
continue without terminating exact stop.
Waits for the end of program of the
specified channels (current channel not
specified) Example: programming a delay
time after the Start command.
N30 START(2)
N31 G4 F0.01
N40 WAITE(2)
Sets the markers "marker no." in the same
channel without affecting current
processing. SETM() remains valid after
RESET and NC START.
Deletes the markers "Marker No." in the
same channel without affecting current
processing. All markers can be deleted with
CLEARM(). CLEARM (0) deletes the marker
"0". CLEARM() remains valid after RESET and
NC START.
