The Continuous Function Chart Editor (CFC)

No snap grid is used for the continuous function chart editor so the elements can be placed anywhere. Elements of the sequential processing list include boxes, input, output, jump, label, return and comments. The inputs and outputs of these elements can be connected by dragging a connection with the mouse. The connecting line will be drawn automatically. The shortest possible connection line is drawn taking into account existing connections. The connecting lines are automatically adjusted when the elements are moved. If the case arises where a connecting line cannot be drawn simply because of lack of space, a red line will be shown between the input and the associated output instead. This line will be converted into a connecting line just as soon as space is available.

One advantage of the continuous function chart as opposed to the usual Function Block Diagram Editor is the fact that feedback paths can be inserted directly.

The most important commands can be found in the context menu.
