When the device is delivered, the device does not have an access code and is equivalent to 0000
(open).
WLAN passphrase
A connection between an operating unit (e.g. notebook or tablet) and the device via the WLAN
interface which can be ordered as an option is protected by the network key. The WLAN
authentication of the network key complies with the IEEE 802.11 standard.
When the device is delivered, the network key is pre-defined depending on the device. It can be
changed via the WLAN settings submenu in the WLAN passphrase parameter.
General notes on the use of passwords
• The access code and network key supplied with the device should be changed during
commissioning.
• Follow the general rules for generating a secure password when defining and managing the access
code or network key.
• The user is responsible for the management and careful handling of the access code and network
key.
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.

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.
