Need Help!- Password Protect Programs

[Kurt Tedford]

We have several productions programs that we run over and over again. I would like to password protect or lockout the operater from making any changes to the programs. Any ideas?

The VMC is a Harginge P3-600 with a Fanuc Oi-MC control

You should have a mem lockout keyswitch, if the OEM has originally installed one on the operator panel.

most fanucs that ive worked on had a key switch ,
another alternative is to tell the operator he's fired if he makes any edits

Protection is possible only for 8000 and 9000 series programs through parameter no. 3202#0 & #4 on 0i MB.
0: not protected
1: protected
These bits can also be "locked" by specifying KEYWD (parameter 3211) and PASSWD (parameter 3210).
And, you do not have to forget the PASSWD, which is not displayed on the screen.

I've numbered a program in the 8000's before - unlocked access then sent it to the machine - then relocked it in the parameters. Then all I did was wirte a real basic program with the only function being to call the hidden one by M98 sub-program call function.
If you do this then if your operator screws with anything, nothing will work (only leave the most basic of functions in your accessible program).
