Fanuc 10t Lathe Programming Manual
Fanuc Training Manual
If you are trying to pull a program out of the Mori's control onto a PC: AND If you do not have a RS-232 Port. Then you need a BTR board (Behind the Tape Reader) to be installed. This will allow you to interface a PC with the control.
Cnc Lathe Programming Manual
It tricks the control into thinking it is receiving punched tape. Basically a binary to punch tape translator. On my setup: I can't pull a program. So my edits only should be done on the PC. Then sent back to the CNC. Some BTR's will send & receive. You will also need some kind of communication software and a cable wired correctly between the PC & CNC.
There are companies that offer a full package. Google Behind the Tape Reader.
