4.2.4 Access authorizations
The user has two access levels via the data interface:
•
The first level is the password level with read authorisation
•
The second level is the service level with read and write authorisation
The password level enables the user to read data and parameters from the using the login
password. This password level does not allow you to write parameters.
The authorized service user can also use a second password to access the service level (W5
password according to IEC 62056-21). This enables him to write certain parameters (refer to Table 4.4
- Obis codes).
