A Ladder Logic Diagram (LLD) is a graphical programming language used primarily for Programmable Logic Controllers (PLCs) in industrial automation. It is based on the circuit diagram of relay logic and is designed to look like a ladder, with two vertical lines called rails and horizontal lines called rungs1.
Structure and Components
The rails represent the power supply, with the left rail typically representing the positive voltage and the right rail representing the ground or common connection. The rungs contain the control logic, with input conditions on the left and output actions on the right1.
Key Components
Rails and Rungs: Vertical lines are called rails, and horizontal lines are called rungs.
NO/NC Switches: Normally Open (NO): Open when not actuated, closes the circuit when activated. Normally Closed (NC): Closed when not actuated, opens the circuit when activated.
Output/Coil: Represents output devices such as motors, valves, and lights1.
