About graphic displays and graphic objects
A graphic display represents the operators view of plant activity. The display can show
system or process data and provide operators with a way to write values to an external
data source. The data source can be memory or a device such as a programmable
controller or an OPC server.
Operators can print the display at run time to create a visual record of tag values, object
states, or current messages.
The elements that make up a graphic display are called graphic objects. You can create
objects in the Graphics editor, or copy them from a global object display, from a graphic
library, or from another application.
For information about creating and copying graphic objects, see Chapter 20.
You can use up to 1,000 tags per graphic display. This limit includes the tags contained in
embedded variables.
Compact applications (applications running on PanelView Plus Compact terminals) have
a limited number of displays.
Before creating graphic displays, specify project settings. Project settings determine important
aspects of your graphic display such as size and position. For more information, see page 4-11.
