2.7.1

Protecting access via hardware write protection

Write access to the parameters of the device via the local display or operating tool (e.g.
FieldCare, DeviceCare) can be disabled via a write protection switch (DIP switch on the
main electronics module). When hardware write protection is enabled, only read access to
the parameters is possible.
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 or operating tool (e.g. FieldCare,
DeviceCare) can be protected by the modifiable, user-specific access code (→  116).
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 (→  74), 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
(→  111).
