9-2 Creating an i.LON 1000 Web PageOverview of Creating i.LON 1000 Web PagesThe i.LON 1000’s embedded Web server application and the i.LON 1000’s embedded dataserver application work together to serve web pages that reference network variables to astandard web browser.The i.LON 1000’s data server provides an anchor point to which both input and outputnetwork variables can be bound. Additionally, it knows how to pass the current value ofnetwork variables to the Web server, and how to accept data from the web server topropagate to its output network variables.Prior to returning a web page to a browser, the web server parses the page searching for aspecial HTML tag indicating a network variable reference. The web server substitutes thecurrent value of a network variable for this tag when returning information to the browser.Thus, any network variable defined on the i.LON 1000 can be referenced in a web page justby incorporating the correct HTML tags.Web pages may be constructed with any off-the-shelf HTML editor.Required HardwareYou will need the following hardware for this tutorial:• 1 i.LON 1000 Internet Server (with FTT-10 channel)• 1 LonPoint DI-10 Digital Interface Module• 1 LonPoint DO-10 Digital Output Interface ModuleRequired SoftwareYou will need the following software for this tutorial:• LonMaker Integration Tool version 2.0 (or higher) with the LonMaker Basic ShapesStencil.• A standard FTP client application such as CuteFTP or AbsoluteFTP• Netscape Navigator (version 4.0 or higher) or Microsoft Internet Explorer (version 4.0 orhigher)Setting Up The HardwarePhysically attach the DI-10, DO-10, i.LON 1000 and LonMaker PC to the FTT channel asshown in Figure 9-1. Attach the i.LON 1000 to the 10BaseT network. Check with yoursystem administrator for a valid IP address, subnet mask, and gateway for the i.LON 1000.Be sure there is another PC on the IP network equipped with a browser and an FTP client.
