Processor Security Options
SLC 500 and MicroLogix processors have a built-in security system, based on numeric
passwords. Processor passwords consist of up to 10 digits (0-9). Each processor
program may contain two passwords, the Password and the Master Password. (These
are different than the PLC-500 A.I. security system passwords discussed in the previous
section.) The Master Password essentially overrides the password. The idea is that all
the processors in a project would have different Passwords and the same Master
Password. That way, you can restrict some peoples’ access to specific processors, and
others can have access to every processor in the project without having to keep track of
multiple passwords.
Important If you define a Master Password, but no individual passwords, users will NOT be
prompted for the Master Password.
Editing a Processor Password
To edit or enter the processor password:
1. From the top level of the online or offline ladder editor, press [F6] Utility .
2. Press [F9] Util2 .
3. Press [F9] Passwrd .
4. Press [F1] Edit . The system prompts you for the new password. (You don’t need
to enter the old password, because you already used it to begin online or offline
editing.)
5. Type the new password (up to 10 digits), and press [Enter] . PLC-500 A.I. will ask
you to type the password again. Type the new password again and press [Enter] .
The new password is entered in the processor.
6. Press [Esc] to continue.
