Access Custom Web Pages
Once a custom web page is copied into the web server module, you
can display that page from your web browser:
Develop a Custom Web
Page Custom web pages can contain standard web content, such as a
company logo, contact information, and links to other web pages. In
addition, you can use ASP functions and other features that come with
the web server module to display and manipulate live controller data.
An ASP file is essentially the same as an HTML file, with embedded
scripting constructs supported by ASP. An ASP file has the file
extension .asp. When an ASP file is requested by a browser, the web
server interprets the ASP file and executes the ASP-specific scripts.
The browser sees only the resulting HTML, not the embedded ASP
scripts.
ASP Function Calls The web server module provides these ASP functions .
If You Custom Web Page Is In Your Web Browser
Configured as the default home Enter the IP address of the web server module.
The web browser accesses the defined web page for the web server module.
If you specify a custom page as the default home page, you can still access the predefined
home page by entering: http://ip_address/index.html
Not configured as the default home page,
but is copied into the /user/Web directory Enter: http://ip_address/user/Web/my_file.html
The web browser displays any custom file if you specify the complete URL to that file.
