Default Web Pages
The default pages are stored in \vfs. The first time the device is started, or after a factory reset request to the Anybus Object (01h), they allow for initial setup and configuration. For more information, see Initial Setup and Account Configuration.
Depending on the role of the user, the default web pages also may provide access to:
Account configuration
Certificate configuration
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 for example pictures, logos and style sheets. To be able to replace the default web pages, the user has to enable admin mode in the Ethernet Host Object (F9h)
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.
