Access to the operating menu via the Web browser

Function scope
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,
device status information is also displayed, allowing users 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
c WLAN". The device acts as an Access Point and enables communication by
computer or a mobile handheld terminal.
For additional information on the Web server, refer to the Special Documentation for
the device
