You can see the newly created node (MyObjectType) in the Information Model Window below “BaseObjectType”. Select it to display its content in the main window.

In this example, we will add three components to the Object Type, two variables of data type Int32 (var1 and var2) and one method (fktSum).

Click on “Select NodeClass” to add a new node and fill in the required information as shown in the screenshot below. To add a TypeDefinition or a DataType which is not already listed in the respective drop-down menu, choose “<Add another node …>” to open a browse window. Confirm your changes by clicking on the “OK” button.

5. Generating Code
For generating the source files, press the “Compile” button (the blue gear-wheel) in the menu bar. When the compilation is finished you will find your generated *.h and *.cpp files located in the output folder (as set in the “New Project” dialog).


6. Export Model as XML
The last step is to export the model to an XML file. Right-click on the model in the Project Window and select Export XML. You will now find a *.xml file next to the model file.
