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.
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.
The parameters placed on the tab are identical with the parameters on the tab Control of the Connect object palette.
Specifies the name of the displayer in the form of reference variable for use in the picture script.
Assignment of application data (metadata) to a graphic object. If the object contains some metadata, the name of the first record will be displayed in the button. Multiple records are indicated by ",...".
The listbox allows user to select active picture event for the displayer. The listbox contains the following active picture events:
The button opens the active picture script to define the active picture event specified by the parameter Event.
Definition of URL address to open a web page from a picture. The address may be set also in the picture script by the function %HI_SetOBJURL.
Input edit box to enter a description of the pointer displayer. In this box, it is possible to use so-called format masks, which allow to display individual attributes of complex value of D2000 system object. In this way, an description can display e.g. current value of connected object. For more information see the topic Format masks.
Possibility to use the Dictionary (to open press CTRL+L).
Note: By using a format mask in a description of the pointer displayer containing of several connected objects, there will be displayed an attribute for each connected object - the parameters Object nr. 1 up to Object nr. 12.
Clicking on the color sample opens the color palette. Selected color will be used for defined description of the pointer displayer.
Definition of a scale range of the pointer displayer. The color sample to select a color for the scale is placed right from the input boxes Range.
The parameters Major and Minor defines a number of ticks of the pointer displayer scale. The parameter Label on every defines a density of labeling. Number of decimal places for can be defined in the parameter Decimals.
Selection of the pointer.
Enable / disable of highlight, setting of its intensity (in the range of 1 to 3) and color.
Selection the color of the scale from the color palette.
Definition of a style of the pointer displayer.
|Displayer is drawn with the frame and background.|
|3D effect - sunken displayer.|
|3D effect - raised displayer.|
|Displayer is drawn with 3D frame.|
Frame and Background
The parameters Frame and Background allows to define colors for the parts (frame and background) of the pointer displayer. Color is defined by selecting from the color palette opened by clicking the button placed right from the color sample of correspondent parameter.
