WAITMC(Marker No., n, n, …)
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 N" in
the specified channels is reached, continue
without terminating exact stop.
WAITE
(n,n) Waits for the end of program of the specified
channels (current channel not specified)
SETM(Marker No., Marker No., …)
Sets the markers "Marker No." in the same
channel without affecting current processing.
SETM() remains valid after RESET and NC
START. SETM() can also be programmed
independently of a synchronized action.
CLEARM(Marker No., Marker No., …)
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. CLEARM() can also be
programmed independently of a synchronized
action.
Note
All the above commands must be programmed
in separate blocks.
Channel names
Channel names must be converted to numbers
via variables (see Section 10 "Variables and
Arithmetic Parameters").
Protect the number assignments so that they
are not changed unintentionally.
