D 5 Animate, Dynamic Graphic Objects
The class of dynamic objects includes objects used in DigiVis both for depicting/observing
process dynamics and for operating the plant, i.e. for operating on process variables. These
objects will be called observation objects and operation objects respectively. All these objects
are located under the Animate menu item. The variables used here for animation of the graphic
display can be newly generated from within the graphic editor or, if already configured, can be
selected from the variable list with the F2 key.
For depicting changing process states, the most commonly used dynamic graphic objects are
the following: bar graphs, fill areas, alphanumeric displays, graphic symbols, self-animated
objects and trend windows. The following techniques are available to animate observation
objects:
•
Display the current value of a variable numerically in any format desired.
•
Display the contents of a string variable as text.
•
Display a configured message text.
•
Display different static graphic objects as a function of configured message types.
•
Depict analog values with bar graphs or arbitrarily shaped fill areas, representing, for
example, levels in containers.
•
Have graphic objects move in the graphic display as a function of an analog value.
•
Have the graphic attributes of an object (colors, line width) change as a function of binary
process values.
•
Have the graphic attributes (colors, line width) of an object change as a function of
messages.
