•From “source” liquid flows into the “tank1”
•Controller “piContinuous1” controls the level of liquid in “tank1”, based on a
predefined reference value, by opening and closing the tank outflow valve.
•Liquid flows from “tank1” into “tank2”
•Controller “piContinuous2” controls the level of liquid in “tank2”

General: Working with diagrams
Deletion of elements:
• Right click on a diagram element
• (preferred) Select the option “Delete Selected Element” in order to delete it from the model. This is recommended in order to keep the model and the diagram consistent
• Select the option “Hide Selected Element” in order to remove the element from the diagram. The element will still exist in the model and can be shown on the diagram by drag&drop.

Create Connection Diagram
•Create a ModelicaML Connection Diagram under the TanksConnectedPI class
•Use components tool from the palette to create components inside the class on the diagram
•Define the types of components
•Use Model Explorer to find the ports
•Drag&Prop ports into respective components
•Arrange the components
•Use the “Connection” tool from the palette for connecting ports
