Creating and using a global-object

How to create a global-object:

1. Select a folder in the project in which you want to create the global-object.
   In the application navigator: The best practice is to create new global-objects below Global variables so that the global variables are created in the subfolder globals of the project and the global variables in these global objects are displayed in a structured way.
   

2. In menu File or from the context menu of the folder, select New and the command Global-Object.

3. In the dialog, enter a name under File Name.
   If possible, do not enter invalid characters (e.g. umlauts, blanks, the character –, numbers at the start) because the file name is automatically used as global-object-name and this name must be a valid →IEC-identifier. But if you need such invalid characters in the file name, delete or replace the invalid characters in Global-Object-Name before you click Finish.
   It is possible to change the global-object-name at any time later.

4. Afterwards click Finish.
   Result::

   1. The global-object (with icon ) is displayed in the views with projects and resources.

   2. The global-object is opened in the →graphical editor.

5. Create or edit the content, e.g. the →global variables. Details: See"Actions within the global-variables-editor".

6. In order to use the global variables within the application, assign the global-object to an ST-→program or a →resource oder →configuration. Best practice is to drag the global-object within the application navigator onto the corresponding object:

   1. Make the application navigator visible.

   2. Point to the global-object that is displayed below the folder Global variables (or a subfolder of it).

   3. Press and hold the primary mouse button and drag the global-object onto the program type ( usually displayed below the folder Project blocks ) or onto the resource or configuratin that is displayed within the application navigator .

   4. Release the primary mouse button.
      Result: The ST-program or the PLC-object (containing the resource or configuration) is enhanced by the necessary reference. This reference is an INCLUDE_GLOBALS directive (see "Declaration of global variables in global-object and its usage in ST", if you need more information on this directive) . If you assigned the global-object to a resource or configuration, this global-object is also displayed in the folder Configuration-Global Variables or Resource-Global Variables.
