(DIP switch on the main electronics module). When hardware write protection is enabled,
only read access to the parameters is possible.
Hardware write protection is disabled when the device is delivered →  131.
2.7.2 Protecting access via a password
Different passwords are available to protect write access to the device parameters or access
to the device via the WLAN interface.
• User-specific access code
Protect write access to the device parameters via the local display, Web browser or
operating tool (e.g. FieldCare, DeviceCare). Access authorization is clearly regulated
through the use of a user-specific access code.
• WLAN passphrase
The network key protects 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.
• Infrastructure mode
When the device is operated in infrastructure mode, the WLAN passphrase corresponds
to the WLAN passphrase configured on the operator side.
User-specific access code
Write access to the device parameters via the local display, Web browser or operating tool
(e.g. FieldCare, DeviceCare) can be protected by the modifiable, user-specific access code
(→  129).
When the device is delivered, the device does not have an access code and is equivalent to
0000 (open).
WLAN passphrase: Operation as WLAN access point
A connection between an operating unit (e.g. notebook or tablet) and the device via the
WLAN interface (→  65), which can be ordered as an optional extra, 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
(→  123).
Infrastructure mode
A connection between the device and WLAN access point is protected by means of an SSID
and passphrase on the system side. Please contact the relevant system administrator for
access.
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.
• For information on configuring the access code or on what to do if you lose the
password, for example, see the "Write protection via access code" section →  129
