LD Elements

When editing a Ladder Diagram (LD) program organization unit (POU), place elements in a language container by dragging them from the LD Toolbox or from a contextual menu accessed by right-clicking. An element is inserted at the current position in the diagram. When inserting subsequent elements, these are placed to the right of the selected element on the rung, then onto the next rung. These elements are available for LD POUs:

While dragging rungs and elements from either the toolbox or within a diagram, the language editor displays the possible drop points. Drop points are displayed as plus signs in a black circle. For rungs, the possible drop points are displayed between the rung handles on the left. For elements, the possible drop points are displayed on the rung.
