Page Area is an important consideration for each application you create. When we refer to page area, we refer to the number of elements, equipment, and processes that you plan to display on a single page. Some systems consist of an overview page, with additional pages displaying a selected portion of an overall system or a complex grouping of equipment. Some systems might show a map of a city with plant or station locations, and then present each separate station or plant on a separate page. Most applications include pop-up dialogs to display controls or details for a single piece of equipment.
Organizational details like this are important, as they help you to the best way to present information to the operators of the system. Always remember that it is better to divide the system into manageable pieces of information than to overload operators with hundreds of elements on a single page.
