Hauser 11
2.6 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.
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. An overview of the most important functions is provided
in the following section.
Function/interface Factory setting Recommendation
Write protection via hardware write
protection switch →  11 Not enabled. Individually following risk assessment.
Access code
(also applies for Web server login or
FieldCare connection) →  12 Not enabled
(0000). Assign an individual access code during
commissioning.
WLAN
(order option in display module) Enabled. Individually following risk assessment.
WLAN security mode Enabled (WPA2-
PSK) Do not change.
WLAN passphrase
(password) →  12 Serial number Assign an individual access code during
commissioning.
WLAN mode Access Point Individually following risk assessment.
Web server→  12 Enabled. Individually following risk assessment.
CDI-RJ45 service interface →  12 – Individually following risk assessment.
2.7.1 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 →  134.
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.
