This document provides details about a PLC training exercise on lift controls. The training will last 45 minutes and involve designing and programming a PLC ladder logic system to control a simulated lift. Components used will include a motor, relays, switches, and a Omron CP1e PLC. Trainees will connect inputs and outputs to the PLC according to a ladder logic program developed on a PC to control the motor, direction, and indicator lights. The goal is to learn PLC programming and sequential logic controls through hands-on wiring and testing of the lift simulation.
