Configuring user security

A user who has security supervisor access can set up security privileges
for up to eight users, giving each different access privileges, for both the
Tracer MP580/581 operator display and the Rover service tool. Any user
can view all displays on the Tracer MP580/581 operator display; however,
a security supervisor can set up security to prevent unauthorized users
from changing variables or overriding outputs at the operator display.
A security supervisor can also set up security to prevent unauthorized
users from downloading or deleting variables, overriding inputs, down-
loading or deleting a Tracer graphical program, clearing memory on the
controller, and performing a flash download to the controller.
After security is established, users are prompted to log on with a pass-
word when they attempt to perform security-protected functions.
Note:
A logged-on user loses access to security-protected functions if
an action is not performed for 30 minutes.
