until it is removed. The entire virtual file system can be disabled using configuration software
on the Ethernet Settings page.
Replacing the virtual files makes it possible to for example replace the default logo by
uploading a new logo named ‘\logo.jpg’. It is also possible to make links from a web page to
the virtual configuration page. In that case the link shall point to ‘\config.htm’.
The virtual file system contains the following files:
\index.htm - Points to the contents of config.htm
\config.htm - Configuration frame page
\configform.htm - Configuration form page
\configform2.htm - Configuration form page
\store.htm - Configuration store page
\logo.jpg - HMS logo
\configuration.gif - Configuration picture
\boarder.bg.gif - picture
\boarder_m_bg.gif - picture
FTP Server
It is possible to upload/download files to/from the file system using a standard FTP client.
Depending on security settings, different parts of the filesystem can be accessed by the user (see
Security above). Internet Explorer within the Windows Operating System, for example, may also
operate as an FTP Client simply by preceding the address in the address bar with “ftp:” instead
of “http:”
The FTP Server can be disabled via configuration software on the Ethernet Settings page.
Server Side Include (SSI) Functionality
The SSI functionality makes it possible to display or alter I/O data and configuration settings
on a web page. It is also possible to use SSI functions in email messages (see “SSI in Email
Messages”). Since this functionality allows reading/writing of I/O values in the Fieldbus
Interface, some of the functions described below will use an “offset” parameter to specify the
I/O Location within the Fieldbus Interface. It should be noted that the “offset” parameter will
always refer to a byte-addressed offset from the start of the Fieldbus Interface (i.e. the
“Address Mode” in configuration software should be set to “Byte” and the “Modbus TCP
Address Mode” option should be disabled – see 4.8 Fieldbus Configuration).
