Protecting the Control Panel with a password    
You can protect the Control Panel against unauthorized operation. You can read the settings 
in the Control Panel without having entered a password, however, you are not allowed to edit 
the settings.  
This prevents inadvertent operations and increases security for the plant or machine 
because the settings cannot be edited.  
 
NOTICE 
 
If the password is no longer available for the Control Panel, you first have to update the 
operating system before you can make any changes in the Control Panel. 
All data on the HMI device is overwritten when you update the operating system.
