13.2 CFC Editor
The CFC Editor, provided by the 'CFC Editor' plug-in, is available for programming
objects in the programming language Continuous Function Chart (CFC), which is an
extension to the IEC 61131-3 programming languages. You choose the language when
adding a new POU object via the 'Add Object' command in your project.
The CFC Editor is a graphical editor.
The editor will be available in the lower part of the window which opens when
opening a CFC POU object and which also includes the Declaration Editor in its upper
part.
Abb. 312 CFC Editor
The CFC Editor in contrast to the network editors allows free positioning of the
elements, which for example allows direct insertion of feedback paths. The sequence
of processing is determined by a list which contains all currently inserted elements and
can be modified.
The following elements are available in a toolbox for inserting: box (operators,
functions, function blocks and programs), input, output, comment, label, jump,
composer, selector.
The input and output lines of the elements can be connected by dragging a connection
with the mouse. The course of the connecting line will be created automatically and
noticeing the shortest possible way. The connecting lines are automatically adjusted as
soon as the elements are moved. See also: Insert and arrange elements.
You may change the dimension of the editor window by zooming: Use the button
in the lower right corner of the window and choose between the listed zoom factors.
Alternatively you may select the entry ... to open a dialog where you can enter any
arbitrary factor by typing.
The commands for working in the CFC Editor can be called from the context menu or
from the "CFC" menu which is available as soon as the CFC Editor is active.
