Safety IT security
We only provide a warranty if the device is installed and used as described in the Operating
Instructions. The device is equipped with security mechanisms to protect it against any inadvertent
changes to the device settings.
IT security measures in line with operators' security standards and designed to provide additional
protection for the device and device data transfer must be implemented by the operators themselves.
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. An overview of the most important functions is provided in the following section.
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). Is equivalent to hardware write protection in terms of functionality.
• 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.
