Adding a POU to a program
- Start editing the real-time application.
- In the menu bar, click Program.
- In the catalogue, navigate to the Program Organisation Unit (POU) you want to add by browsing the categories or by using the filter.

If a Program Organisation Unit written in Function Block Diagram contains multiple networks, the order of execution depends on the last element's position on the worksheet:
- From top to bottom.
- On the same level from left to right.
- Drag-and-drop the Program Organisation Unit to the desired position in the worksheet.
