Password Protection
Password protection can be configured for buttons and input fields to prevent
operation of the Touch Panel by unauthorized personnel.
5.1 Password Level and Access Permissions
During the configuration phase with ProTool, the configurer assigns the but-
tons and input fields hierarchically ascending password levels from 0 to 9.
When a password is assigned to an individual user or to a whole user group,
the permission to execute functions at a specific level is assigned simulta-
neously.
After logging in with a password of a specific password level on the Touch
Panel, permission to execute functions is granted at that password level and
functions at lower levels.
If a function is configured with password level 0, no password need be entered
in order to execute this function. The functions assigned at this level, the low-
est in the hierarchy, have little or no effect on operation. These functions nor-
mally do not have input options; one example is Open Message Pages.
To call a password level 0 function, you do not have to enter a password. If you
call a function that is assigned to a higher level, the Touch Panel will prompt
you to enter a password.
Levels 1 to 8 should be assigned by the configurer according to the signifi-
cance of the respective function. The supervisor (superuser) is responsible for
assigning a password level to a password as part of his password management
duties.
Only the superuser has the rights to execute functions assigned password
level 9. The superuser has access to all the functions of the Touch Panel.
Only the superuser is authorized to perform password management on the
Touch Panel. Password management involves assigning and changing pass-
words.
