1) Two–path wait function
When an M code is specified for the NC and loader control of the
FANUC Series 16–TA, 16–TB, 18–TA, or 21–TB a two–path wait
can be executed.
D When a waiting M code is specified in the programs for the NC and
loader, either can wait for the other in the specified block.
D The M code must be specified in a single block as shown below:
M m
;
m: Waiting M code number
2) Three–path wait function (for the Series 16/18)
A system featuring a two–path (TT) NC and loader control can use
a three–path wait function.
The range of three–path waiting M codes is specified in the main and
loader parameters (parameters 8110 and 8111) in the same way as the
range of two–path waiting M codes is specified.
D A wait pattern is specified after address P in the same block as the
waiting M code. Address P is used to distinguish a three–path wait
from a two–path wait.
D The M code must be specified in a single block, as shown below:
M m
P p ;
m: Waiting M code number
p : Number specifying a wait pattern
