the motherboard). When hardware write protection is enabled, only read access to the
parameters is possible.
Hardware write protection is disabled when the device is delivered → 194.
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.
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
(→ 192).
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 (→ 99) 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.
• For information on configuring the access code or on what to do if you lose the
password, see the "Write protection via access code" section → 192
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.
