10 WEB-Server
This Gateway also contains a WEB-Server by default. In the initial state there is a welcome page
on the Flashdisk, that presents the device’s system parameters.
The WEB-pages can be changed by the customer as desired and via FTP they can be written on
the Flashdisk.
The "Server Side Include"-functionality is made available in order to be able to generate dynamic
WEB-pages that display process data on the WEB-page or pass on data from the WEB-page to
the process, which means that placeholders are used for the process data on the HTML-page.
Data exchange through Server Side Include (SSI)
In case the UNIGATE detects the variable’s placeholder, that is described by a variable’s name
(see below), it places the corresponding String at the variable’s place. The other way round
Strings, that are passed on via „POST“ by the HTML-page with the corresponding variable name,
are copied in to the corresponding Script buffer.
The Syntax looks as follows:
<?--#exec cmd_argument='xxxxx'-->
For xxxxx the following expressions are possible:
- DisplayFWVersion
- DisplayBLVersion
- DisplaySerial
- DisplayMacID
- DisplayStationName
- DisplayStationType
- DisplayVendorID
- DisplayDeviceID
- DisplayIP
- DisplaySubnet
- DisplayGateway
These expressions are self-explanatory and they reflect the corresponding values that have
been preset by the Firmware.
The following expression is required for the exchange of any process data between the Script in
the Gateway and the WEB-page:
- DisplayScriptVar,Variablenname
