CFC Editor

Cursor symbol 

Requirement: in the Toolbox view Pointer is selected.

The icon indicates that you can edit in the editor. Select elements or connections to move them or to select commands.

Cursor symbol 

Requirement: an element is selected in the Toolbox view.

With a mouse click in the editor the selected element is inserted. Alternatively, you can drag-and-drop an element into the editor.

Drag-and-drop of a function block instance from the declaration into the editor

Requirement: a declaration line is selected in the declaration of the CFC.

The instance is inserted as a function block with block name and block type and all connections.

Drag-and-drop of a variable from the declaration into the editor to a block connection

The variable is inserted as input or output with connection to the focused block connection.

Tip: The cursor indicates whether you are focusing on a valid location for a variable.

Drag-and-drop of a variable from the declaration part into the editor

Requirement: The respective element is selected in the declaration.

• Function block instance: a function block with the corresponding data type is created.
• Declaration of VAR_INPUT or CONSTANT: an input element is inserted.
• Declaration of VAR_OUTPUT: an output element is inserted.
• Declaration of VAR, VAR_GLOBAL: a window opens at the insertion position where you can select whether an input or an output element is to be inserted.

When a variable is dragged and dropped from the declaration part onto an existing replaceable element, the existing element is replaced.

Drag-and-drop of a function block or programming block from the project tree or the Library Manager into the editor

A function block element with the corresponding type is inserted.

• If a function block is dragged and dropped onto an existing connecting line and both an input and an output of the function block are compatible with the data type of the line, the function block is inserted on the line. In this case, its first matching input and output are connected to the elements that were previously connected by the connecting line.
• When a function block is dragged and dropped onto an existing function block, the existing function block is replaced.

Rearranging the order of inputs and outputs within a function block using drag-and-drop.

Requirement: the text field of the input or output to be reordered to another position is selected.

[Ctrl] + click in the programming area

Requirement: an element is selected in the Toolbox view.

As long as you hold down [Ctrl] , a selected element is created each time you click in the programming area.

[Ctrl] + right arrow

Requirement: in the CFC program, exactly one output pin is selected for an element.

The selection is moved so that the input pin is selected at the end of the connecting line. If there are several pins, all of them are selected.

Example:

[Ctrl] + left arrow

Requirement: in the CFC program, exactly one input pin is selected for an element.

The selection is moved so that the output pin at the beginning of the connecting line is selected. If there are several pins, all of them are selected.

Example:

Drag-and-drop from one pin to another

A connecting line is inserted between the 2 element pins.

Drag-and-drop from a pin to a function block

Drop can be performed on a pin or on the text field of a connection.

For extensible operators (for example ADD) the drop can also be done within the function block. The following behavior applies:

If there are still unconnected input pins, the uppermost free pin is connected. If there are no more unconnected input pins, then a new pin is automatically inserted at the bottom.

Command Connect selected pins

Requirement: you have selected several pins. The pins are marked in red.

Move inserted element so that it touches the pin of another element.

Requirement: option Enable AutoConnect is enabled.

The touching pins are automatically connected to each other.

The connection icon is located in the upper right corner in the editor. A green icon indicates collision-free connections. A red icon indicates collisions. Clicking on the icon opens a menu with commands for collision processing, for example the command Show next collision.

Requirement: you have selected a connection and the command Connection mark.

Instead of a long connecting line, a connection is represented by connection marks.
