CFC Editor, Page-Oriented¶
Note
POUs that you generate with the page-oriented CFC editor cannot be converted into ordinary CFC and back. You can copy the elements between both of these editors by means of copy-and-paste (from the clipboard) or the drag-and-drop function.
You can insert additional pages from the toolbox or copy existing pages by means of copy and paste and selecting the page from the list on the left edge of the editor view. The size of the page is changed by means of the Edit page size command.
Connections between two pages are established with the Connection Mark - Source and Connection Mark - Sink elements. When you drag a connecting line from one input or output to a page column, the connection mark is set automatically. The “List components” feature provides all defined connection marks - source.
Navigation: You can use the arrow keys to set the selection in the diagram from one element to the next. This moves automatically from one connection mark to the next or previous page.
Note
Please note that input and output elements can also be positioned on the left or right edge (highlighted in gray by default) in order to save space.
Order of execution
CODESYS processes the pages from top to bottom, according to the order visible in the left part of the editor view. Within one page, the processing sequence of elements is like in the standard CFC editor. The processing sequence cannot jump arbitrarily between pages.
