5.6 Password Protection
Purpose
During configuration using ProTool, operating elements, such as input fields,
buttons and function keys, can be protected against unauthorized use by applying
a password. Important parameters and settings can then only be modified by
authorized personnel.
Password hierarchy
Hierarchically defined password levels 0 to 9 are provided for password protection.
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 simultaneously. If an
user is assigned to password level 4, he only has the permission to execute
functions in password levels 0 to 4.
Password level
Password level 0:
The functions assigned to this level, the lowest in the hierarchy, have little or no
effect on operations. They normally concern functions without any input options,
such as displaying messages.
In order to trigger functions assigned to password level 0, no password needs to
be entered.
Password levels 1 to 8:
Functions are assigned to levels 1 to 8 according to their increasing importance.
Before triggering a function with a password level greater than 0 the MP270
requests the corresponding password to be entered.
Password level 9:
Only the superuser has the rights to execute functions assigned to password level
9 (system administrator or service technician). The superuser has access to all the
MP270 functions.
