Password protection consists of three elements:
•
Password level
•
User group
•
Password
Each menu item is assigned an password level. Password levels are numbered
0, 1, 2 and 3.
Menu items are assigned to different password levels in order to assure that specific menu
items can only be changed by authorized users.
The members of a user group are authorized to access a specific password level, i.e. to
change the menu items at that level.
Some user groups are set-up at the factory.
A user group can be made up of one or more users.
Every user group set-up in the system has a password.
The password consists of six digits which can be entered via the numeric keypad.
Passwords are pre-assigned for the factory-set user groups.

block applications. When configuring function blocks, existing applications with
their configurations and links can be damaged or destroyed.
Technical Bulletin "AO2000 Function Blocks – Descriptions and Configuration"
(publication no. 30/24-200 EN) contains complete information on the "Function Block"
concept as well as detailed descriptions of the individual function blocks.
