Chapter 2
Configuring Passwords and Privileges

2-9

As system administrator, you can assign read and write privileges for each
program file in a processor in order to limit the ability of users to view or
change it.

Important:

•

You cannot modify read and write privileges to system (file 0) or
undefined files.

•

Removing both read and write access from class 1 for a program file
prevents even you, the system administrator, from accessing that file.
Make sure that class 1 retains whatever access is necessary to each file.

•

Download screening for DTEP violations is directed at program files for
which classes 2-4 have write privileges. If you generate files offline that
control critical logic, you must remove all privileges to write to these files
from classes 2-4 before DTEP will let you download the files.

To specify read and write privileges for a program file, follow the steps on
the left.
