7.2.2 Authorization
There are authorization levels for each parameter, which allow or forbid read and
write accesses to the parameter. The operator interface initially starts with the
lowest authorization level, which mostly only allows read access to parameters.
You obtain more rights by inputting the corresponding password.
The user can change the password.
• Parameter /System/Authorization For Standard Protection (2.06.02)
The device is supplied with the password: "2222"
The current authorization level is indicated by the color of the password field.
Write protection - red entry field
In this authorization level, the user typically has only read access to standard
parameters.
Standard protection - green entry field
In this authorization level, the user typically also has read access to extended
parameters and write access to standard parameters.
Online mode
Authorization is executed directly on the device, i.e. the device assigns an appro-
priate authorization level.
Offline mode
You can authorize yourself for a higher authorization level with a password, pro-
vided that it is included in the loaded offline authorization parameters.
Note
In offline mode, it is not possible to authorize oneself with a password that is pre-
sent in the device but is not included in the offline authorization parameters.
Note
The combination "0000" is not permitted as a password. Setting the password to
"0000" disables access with this authorization level. Access is then only possible
using the service password. The service password can be requested from Tech-
nical Assistance by an authorized person.
