Web Server

6.1

General Information

Category: extended

The built-in web server provides a flexible environment for end-user interaction and configura-
tion purposes. The powerful combination of JSON, SSI, and client-side scripting allows access
to objects and file system data, enabling the creation of advanced graphical user interfaces.

The web interface is stored in the file system, which can be accessed through the FTP server. If
necessary, the web server can be completely disabled in the Ethernet Host Object.

The web server supports up to TBD concurrent connections and communicates through port 80.

6.2

Default Web Pages

The default web pages provide access to:

•

Network configuration parameters

•

Network status information

•

Access to the host application ADIs

The default web pages are built of files stored in a virtual file system accessible through the vfs
folder. These files are read only and cannot be deleted or overwritten. The web server will first
look for a file in the web root folder. If not found it will look for the file in the vfs folder, making it
appear as the files are located in the web root folder. By loading files in the web root folder with
exactly the same names as the default files in the vfs folder, it is possible to customize the web
pages, replacing such as pictures, logos and style sheets.

If a complete customized web system is designed and no files in the vfs folder are to be used, it
is recommended to turn off the virtual file system completely, see the File System Interface
Object.
