Dialog Options - CFC Editor

Enable AutoConnect

: When you drag and paste a CFC element onto the editor's workspace, TwinCAT automatically connects unlinked pins that "touch" each other. Make sure that you do not create any unwanted connections when you move elements!

Prepare values in implementation part

: In online mode, you can also prepare variable values for writing and forcing in the implementation part of the CFC function block. In addition, TwinCAT displays the values that have just been prepared in the inline monitoring box of the variables in angle brackets.

Display grid points

: In the editor, grid points are validity areas at which you can position the elements.

Show box icon

: TwinCAT displays function blocks in the CFC editor that are linked to a bitmap as symbols.

Requirement: You have either created the link for a function block or a function in the object properties or loaded it using a library.
