Ladder diagrams primarily illustrate what?

Ladder diagrams are used to show the control logic that decides when an output should energize. They focus on the control devices—pushbuttons, switches, relays/contacts, sensors, and other inputs—and how signals flow through those devices to energize an output. The diagram is drawn to depict the path of control signals, not to list every electrical component or to detail the entire power circuit. So, while you might see a power source or the output device represented, the primary purpose is to illustrate the control devices and how they interact to control the outputs.
