I have an old custom machine with a Fanuc Series 15-M PMC and 14 axis'. I need to do some modifications to the ladder program but I am currently unable to upload it from the PMC. I've tried FAPT Ladder I, II and III with no luck. I've also tried using a Handy File without any luck. Is it even possible to upload the ladder program using a pc? Or is this model too old?

I would appreciate any advice or assistance.

Thanks,

Greg Elliott
