7.1.10 Access Protection for Individual HTML Pages
With the FP Web-Server, Password protection for ALL HTML pages containing PLC data can
be switched on or off.
To protect individual pages only, enter the {PW} command in the HTML code. The text {PW} is
no longer displayed on the browser after sending the page using [SEND] to the FP Web-Server.
Three variations are possible:
1. Default password:
{PW} protects the page by user name and password
2. Individual password:
With the marker {PW_pppp} set in the HTML code, the user name specified in the base
configuration and the password pppp of the new command will be asked for before
displaying the data. Hence you can assign different passwords to different HTML
pages.
3. IP lock security:
The tag {PW_ip.ip.ip.ip} enables only the computer with the IP address ip.ip.ip.ip to
display the page, hence enabling designated computers to display certain HTML pages.
The enabled IP address "ip.ip.ip.ip" can be a single address such as 192.168.200.55 or
it can define an address range by using asterisks ('*'). For example, the tag
{PW_192.168.200.*} allows clients with an IP address from 192.168.200.1 to
192.168.200.254 to access the protected HTML page.
If the computer has the wrong IP address, the following standard dialog is displayed by
the browser:
However, the FP Web-Server will not accept any entry.
The individual page protection should be switched ON in the configuration.
