Protecting access via hardware write protection
Write access to the device parameters via the local display, Web browser or operating tool (e.g.
FieldCare, DeviceCare) can be disabled via a write protection switch (DIP switch on 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.
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.
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, 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.
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.
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.
For detailed information on device parameters, see:
The "Description of Device Parameters" document
Access via service interface (CDI-RJ45)
The device can be connected to a network via the service interface (CDI-RJ45). Device-specific
functions guarantee the secure operation of the device in a network.
