The "lock status" is shown at the status bar in the bottom right corner
(padlock) as seen in the following screen.
Figure 2-8: Device Locking Menu
To lock the device, the user must enter a password.
Figure 2-9: Password Input Screen
To unlock the controller, the user must enter the password as entered
during the locking of the controller. The password will be stored in

any user with a LAD connected to the controller. It is intended to keep
the uninformed user from accidentally changing configuration settings.
