2.7
Device-specific IT security
The device offers a range of specific functions to support protective measures on the
operator' s side. These functions can be configured by the user and guarantee greater in-
operation safety if used correctly. The following list provides an overview of the most
important functions:
Function/interface
Write protection via hardware write
protection switch → 11
Access code
(also applies to web server login or
FieldCare connection) → 11
WLAN
(order option in display module)
WLAN security mode
WLAN passphrase
(Password) → 12
WLAN mode
Web server → 12
CDI-RJ45 service interface→ 12
2.7.1
Protecting access via hardware write protection
Write access to the parameters of the device 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 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 → 117.
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
(→ 116).
When the device is delivered, the device does not have an access code and is equivalent to
0000 (open).
