1 Basics

This UML class diagram example illustrates the basic functionality of the UML class diagram.

Sample project: TF1910_UmlCD_Sample1_Basic.zip

ClassDiagram_1

This class diagram illustrates the structure of the PLC project. It contains various PLC elements (such as function block, interface, global variable list etc.).

The class diagram also illustrates the relationship between the elements (inheritance between function blocks, implementation of an interface, instantiation of a function block).

ClassDiagram_2

This class diagram explains and explores the following basic functionalities:

  • Visualize existing element from the cross-references on the diagram
    • Display the "Toolbox" window
    • Select FB_InfoData on the class diagram
    • Toolbox: elements that are related to the selected element but are not included in the class diagram are displayed under the headings "Incoming cross references" and "Outgoing cross references".
    • You can drag and drop the element onto the diagram, so that the element is shown in the class diagram.
    • For more information see: Adding existing elements to a diagram.
  • Visualize existing element from the project tree on the diagram
    • Select an element of type POU, INTERFACE, GVL or DUT in the project tree and drag and drop it onto the opened class diagram.
    • Drop it in a suitable location to visualize it there.
    • The corresponding element is then displayed in the diagram. If relationships with already shown elements exist, these are displayed automatically.
    • For more information see: Adding existing elements to a diagram.
  • Adding new elements or creating new relationships between elements
