Function range
Thanks to the integrated Web server, the device can be operated and configured via a Web
browser and via a service interface (CDI-RJ45) or via a WLAN interface. The structure of
the operating menu is the same as for the local display. In addition to the measured values,
status information on the device is also displayed and allows the user to monitor the status
of the device. Furthermore the device data can be managed and the network parameters
can be configured.
A device that has a WLAN interface (can be ordered as an option) is required for the
WLAN connection: order code for "Display; operation", option G "4-line, illuminated; touch
control + WLAN". The device acts as an Access Point and enables communication by
computer or a mobile handheld terminal.
