life, puter techno logy, automatic control technology and power electronic technology rapid development, the elevator has bee a symbol of urban material civilization. Especially in highrise buildings, the elevator is an indispensable vertical transportation equipment. Traditional relay elevator control system, due to the mechanical and electromagic relay inertia big, greatly reduces the reliability and security of the elevator system. In order to ensure the efficiency and reliable securities, the control method of elevator must be changed. The programmable logic controller (PLC), which develops based on sequence logica
