For programming with the editor, see the following instructions: ⮫ “Programming in Instruction List (IL) ”

Inserting and arranging elements

You can insert elements with the help of the commands of the “FBD/LD/IL” menu of the context menu. You can also drag a new network from the ToolBox into the implementation part of the editor.

You can use the usual commands in the “Edit” menu to cut, copy, paste, and delete elements. Copying also works by dragging and dropping while holding down the [Ctrl] key.
