An XML file format is used to define a Niagara presentation. This file format is called “Px” for presentation XML and the term “Px” is commonly used to describe the Niagara presentation architecture. Presentation is a term that describes how Niagara visualizes information (text, graphics, alarms, and so on) across heterogeneous media – such as: Workbench, desktop browsers, handheld devices, and so on. Niagara uses “presentation xml” (Px) to accomplish this. Figure 15 shows an example of a Px file in the Text Editor (Px source file), the Px Editor view, and as displayed in the Px Viewer.
