parts counter

any ideas on a pin i can link to to make a parts counter?
i cant find any linked to "m02"

i really wanted it to work so as i could get a signal on every " / O100 ENDREPEAT " line, then the program would simply stop at a specific count. ( i already have "net outa_bar <= halui.program.block-delete.on" hooked up to stop pgm when the barfeeder is out) it would be nice to be able to preset an amount of parts when i load up a 5.5mtr length of bar! anyway, i geuss i can use a m1xx code, just was looking to make it invisible to the programmer thats all.

is the repeat number available anywhere?

i also tried using "net line_number => motion.program-line", but it is erratic and jumps to "0" while changing tools. it also is wrong, as i would have to compare it to line 10, or wherever the repeat starts from.

Ok, im currently trying to get an M1xx code working. you see, i normally load 4.5metre bars into the machine and run off as many parts as needed, i have the "out of bar" switch connected up to
net outa_bar <= halui.program.block-delete.on
and
/ O100 ENDREPEAT
makes it stop in such a situation.
But !
i want to be able to set a value while the program is running, not have to rely on the
/ O100 REPEAT [12]
value, giving me the ability to have a visible display on how many parts to go, and even possibly work out how long.

p.s. having a lot of trouble trying to make an m1xx code work, it was much easier when they are hooked up to "actual" pins.
