5–2 Assigning Passwords to Your Program and Data Files
Publication
65566.5.1 - October 1996
The software is factory–configured for access privileges for security.
We assigned:
• privileges to privilege classes
• read or read/write access to program and data files
Class 1 has all privileges. The password to class 1 is held confidential
at the factory. We assigned privileges to classes 2-4 at the factory, and
withheld the privilege to modify privileges from these classes.
Important: As a result of withholding the capability to modify
privileges in classes 2-4, you cannot modify privileges on the
following screens:
• Privilege screen
• Data File Privilege screen
• Program File Privilege screen
Since you cannot modify privileges, our purpose in describing access
to these screens is informational: to show you how we assigned
privileges. We did this to protect the proprietary clutch/brake control
program and data files.
Important: With this privilege structure, you may create program and
data files for your own ladder logic. You will have RW access to them.
Privilege Classes
We assigned combinations of privileges to each of four different classes
from all privileges (class 1) to fewest privileges (class 4). To view the
Privilege screen that allocates privileges, type Alt P from any screen.
You get the Privilege Class Information screen. We assigned the following
privileges to classes 1-4 at the factory. (X = privilege allowed)
