Passwords AGAIN !!!

Hi All
First time posting so here goes. Is it possible in an AB 5/04 processor to give my customer a read only facility?. Thus enabling them to fault find but not modify my program.

All replies greatfully received

The only thing I can think of is using RSLadder....
If the customer has RSLogix then he can get in I guess.
You know there is a checksum in the program that
you can look at and know that something has been
changed.
