General notes on the use of passwords

commissioning.
• Follow the general rules for generating a secure password when defining and managing
the access code or network key.

2.7.3 Access via fieldbus
When communicating via fieldbus, access to the device parameters can be restricted to
"Read only" access. The option can be changed in the Fieldbus writing access parameter.
This does not affect cyclic measured value transmission to the higher-order system, which
is always guaranteed.

2.7.4 Access via Web server
The device can be operated and configured via a Web browser with the integrated Web
server (). The connection is via the service interface (CDI-RJ45) or the WLAN interface.
The Web server is enabled when the device is delivered. The Web server can be disabled if
necessary (e.g. after commissioning) via the Web server functionality parameter.
The device and status information can be hidden on the login page. This prevents
unauthorized access to the information.
