  1. Select the application in the device tree.

  2. Click “Project  Add Object  POU”.

    The “Add POU” dialog opens.

  3. Specify a name and select the “Ladder Logic Diagram (LD)” implementation language.

    Click “Add”.

    CODESYS adds the POU to the device tree and opens it in the editor. An empty network is inserted in the implementation part. The empty network is bounded on the left by a vertical line, which represents a bus bar. The “ToolBox” view is also opened automatically, where the suitable elements, operators, and function blocks are available for LD programming.
