After CODESYS CFC is installed, the two implementation languages are available  in CODESYS: Continuous Function Chart (CFC) and Continuous Function Chart (CFC) - page-oriented. In the Add POU dialog, you can select the CFC languages in the Implementation language list.

Each language has its own editor, but the elements and functionalities are very similar. There you program source code graphically by positioning boxes freely or page-oriented and interconnecting them with connecting lines to form signal flow diagrams (data flow diagrams).

A POU can contain several independent data flows, which is graphically represented as unconnected elements. In addition, feedback is allowed. The execution order in a CFC POU is based on data flow.
