Section D Graphic Display
D-25
The dynamic graphic objects most commonly used for plant operation actions in graphic
displays are the following: selection fields, buttons, button fields and radio button fields. These
operation objects can be configured to trigger the following actions in DigiVis:
• Call up a tag allocation faceplate,
• Switch to any other display,
• Write a pre-determined value to a variable,
• Write an operation value to a variable,
• Acknowledge a message.
These operation actions can also be initiated by a display object.
In DigiVis, when a graphic display is updated, all dynamic objects are placed in front (on top) of
any static display elements. This can be altered by making the static elements part of a
dynamic object and designating them as foreground or background components within that
object. Such grouping makes it possible, for example, to display scale markings on a bar graph.

shown in the general section of the parameter dialog. It can be changed by the user at any
time. Object names must be unique within a graphic display.
