Ladder Diagram (Relay Ladder Diagram) is the specialised schematics used to industrial control logic systems that is one or more networks of contacts, functions, function blocks, data elements, labels, and connective elements. The Ladder Diagram differs from regular schematic diagrams to electronics technicians primarily in the strict orientation of the wiring: vertical power rails (supply power) and horizontal control rungs (control circuits to represent).
