Hi,

I have an older lathe with FANUC 21-T system DE02 0012, I am looking for a way to 'force' or 'turn on' G0043.5 (DNCI), it is in my PMC but there is no ladder logic to turn it on (I don't have a 'tape mode' switch).

As you may know, above PMC status bit is required to be 'on' for tape mode soft key to appear in AUTO mode... So my PMC has the bit, but the machine builder didn't put anything in the ladder to allow it to turn on.

There must be a way to trick this bit to be 'on', even temporarily, no ?

I've downloaded the ladder and the PMC status etc. via RS232 so even if I needed to make a ladder mod, I'd be willing, but isn't there a way to just turn on that status bit, even if its just while the machine is on (and then lost at power off ?)

Thanks
