Overview
PCL, Extensible Markup Language (XML), Extensible Stylesheet Language (XSL), and Cascading Style Sheet (CSS) files all reside on the PL1000E web server. These files work together to provide a customized view of data gathered by the PL1000E. Illustration 1 displays the relationship between the file types.

The PCL file contains configurations that translate parameters in a web-based solution. The XML custom page file consists of a select group of parameters to monitor and view together gathered from the larger list in the PCL file. The XML, XSL, and CSS files are read by the browser to provide the user with the view of their data.Understanding the XSL File
The XSL file is a stylesheet for the XML file. The .XSL file calls the CSS file to use for the web page, places elements on the page, and associates error strings with certain values gathered from the ECM.The style sheet must be indicated in the XML file. The style sheet controls the format of the data as it will be displayed on the page. The programmer associates an XML file with a specific XSL file in the .xsl?> tag with the filename for the XSL file.Note: Refer to Illustration 2. The preceeding paragraph is referring to line 2, "href= ParameterGroup.xls?>", that is, the style sheet file name.The XSL file does NOT provide formatting such as italics, bold, or other visual formatting. The XSL file calls out a CSS file to provide that formatting for the XML page. The .XSL file contains a series of If-Then type statements written in XSL language. Each of theseIf-Then statements associates a given value returned from an ECM with an error string. The .XSL file also contains code that configures the structure and formatting for numbers and text. Creating Custom XML Pages
Custom Pages allow user-selected parameters to be monitored through a web browser. A Custom Page is configured using an XML file that is published to the PL1000E Web Server.To create a custom page:
Copy the "CSPL1000E_Custom_Page.xml" template. The template is located on the CD that was included with the ECM to a PC with a text editor.Throughout this section of the document, there are references to a Parameter Translation Editor (PTE) .

Modify the information contained in the appropriate XML tags to include the data to monitor.Only the parameters defined in a web translation object in the PCL file are available for display on the Custom Pages.Table 1 contains a detailed description of the XML tags that are shown in Illustration 2 and that are used in the web page. Each XML tag described in Table 1 is the source of a different part of the web page. Refer to Illustration 3. The call outs in Illustration 3 show each area of the web page that is rendered from each XML.
