The palette Connect object is used to create the relations between graphic objects and D2000 system objects. Defining these relations allows, in process D2000 HI, to display and control real values of monitored technology with the use of graphic objects.
After selecting the object, its type and the internal identifier is are displayed in the header. If the object has some reference variable, its name is also displayed.
...

 | Disconnect (remove) the connection - in the selected tab only. |
 | Test the correctness of connection parameters - all parameters in all tabs. |
 | Opens the Object properties palette. This functionality works also vice-versa, i.e. in the Object properties palette opens Connect object palette. |
Note:
The following descriptions of the tabs are not comprehensive. Depending on the object type, some of the parameters, displayed in the tabs, could be disabled.
Parameters used especially for a specific type of graphic object are described in detailed detail in the particular chapter.

- Number A number of palettes in the object: 3; each of the three buttons enable enables one to select the particular palette.
- Properties: N objects can be connected to one graphic object. A display palette will be added to each attached object.
- Only the first object is used for real display (other objects only select graphic attributes from palettes)

Set directly
Quick setting of the values of numerical type objects. Clicking the graphic object (in the picture opened in the process D2000 HI) opens the control window reduced to one input field. You can directly entre enter the value of the connected object. To acknowledge the value, press the Enter key. If you want to cancel this action, press Esc.
...
When clicking the graphic object (in the picture opened in the process D2000 HI), it opens the control window of the connected object. The type of control window depends on the type of connected object.
In the case of graphic information windows (pictures, graphs), this type of control allows to open opening these windows on the D2000 HI desktop. The button Position appears in the tab. It allows us to define the position of the graphic information window in the process D2000 HI.
Set value
...
If the option is checked, then any change of the object attribute will have to be acknowledged by an operator in the process D2000 HI.
Autoclose
If it is checked, the change of the object attribute will close the control window in the process D2000 HI.
For objects of Picture and Graph types, the palette contains the button Position, that which allows to define a position of the information window on the D2000 HI desktop.
...
The parameter Inherit instance allows the multiple opening of the same object (graph, picture) with the same instance number.
...
The parameter Instance allows multiple object instantiation with different instance numbernumbers. It can be used only for active picture/graph , because only these objects can detect its their current instance number and modify their contents or behaviour according to this number. These objects detect the instance number by calling the function HI_GetSelfInstanceID from the script. Multiple object instantiation is used in connection with structured variables, where the instance number can determine the currently used row of a structure, which describes a certain repeated object.
Position...
The button Position allows to define defining the position of the graphic information window on the D2000 HI desktop. Clicking the button opens the following dialog box:
...
The red rectangle defines the position of the information window after opening on the D2000 HI desktop and the behaviour of the picture, from which the window is opened.
- Open picture as popup - the parameter is enabled only for objects of Picture type. The picture, connected to view, will be opened after clicking on the object you connect (button) as a dialog picture with no title bar. To close it, click outside the picture area. Warning: The pictures, which are used as popuppopups, should not be used in any other way (e.g. as a part of other pictures, or opened from a script).
- Open on given position - the window will be opened on a defined position on the D2000 HI desktop.
- Replace on given position - the window will be opened on the defined position and the picture will be closed.
- Open on picture position - the window will cover the picture.
- Replace on picture position - the window will cover the picture and the picture will be closed.
...
The application data (metadata) can be assigned to each graphic object and to a column of the Browser displayer in the System D2000 application. This These metadata are used as a storage room for data. The records are stored in a key/value format (the key and value are a text). Value The value assigned to a key can be gained by calling the function functions %HI_GetMetadata and %HI_GetColumnMetadata. If the object contains some metadata, the name of the first record will be displayed in on the button. Multiple records are indicated by ",...".
