Pointer displayer
Pointer displayer shows the value of one object by means of the pointer, which turns in dependence on a value change of connected object.
An example of pointer displayer displayed in process D2000 HI:
To create the pointer displayer
- In the Drawing toolbar, click on the button Pointer displayer
. - Point the mouse cursor to the position of the first displayer corner and click.
- Point the mouse cursor to the position of the diagonal displayer corner and click.
The parameters for connecting a pointer displayer are being configured in the palette Connect object through the following tabs.
Objects
Object nr. 1 up to Object nr. 12
Each pointer displayer can display the values of as many as 12 objects. So the tab Objects contains input edit boxes to define 12 objects. To define the objects either entering their names or select them from a list opened after clicking the button placed right from the input box.
If you define more than one object for the displayer, the displayer will consist of several subdisplayers. Number of the subdisplayers depends on the number of defined connected objects. However, the subdisplayers are not individual graphic objects and therefore all configuration parameters are common for all the subdisplayers. Then the pointer displayer, in dependence on its height and width, is sectioned either vertically or horizontally.
Color for displaying given object is defined by clicking the button placed left from the input box.
For object of Structured variable type, you must define the column name (the parameter Column) and row number (the parameter Row). For object of Value array type you must define a item (the button L), whose value will be displayed.
Control
The parameters placed on the tab are identical with the parameters on the tab Control of the Connect object palette.
