panel buttons or by System Architect software.

simultaneously. To lock or unlock the menu with System 

Architect software: go to the Tools Menu > Display Screen Security and 
press the lockout button.   If a specifi c parameter is protected, the 
screen says “N/A” or “Change Disabled.”

If the lockout is done from the software, the user can disable the lockout 
only in the software, not by pressing the front-panel but tons.

If the menu is locked and you press any button or turn an Encoder, the 
word “LOCKOUT” is displayed. If a specifi c parameter is protected, the 
screen says “N/A” or “Change Disabled.”
