Configuring Passwords and Privileges
2-10
As system administrator, you can assign read and write privileges for each
data-table file in a processor in order to limit the access of users to view or
change data-table file values.
Important:
• You cannot modify read and write privileges to undefined files.
• Removing read and write access for class 1 from a data-table file prevents
even you, the system administrator, from accessing that file. Make sure
that class 1 retains whatever access is necessary to each file.
To specify read and write privileges for a data-table file, follow the steps on
the left.
