Abstract: This paper introduced the elevator structure, the structure and the working principle of the PLC. Aiming at the elevator of four floors and four stations, design the controller of the elevator which is based on the technology of Mitsubishi FX2N-48MR PLC. This controller is included in the refers to the layer of the elevator,the running controller, the module of register and cancel the instructions from the cabin, the module of register and cancel the instructions from the station hall, the module of choose station and direction, the module of door movement, the module of elevator operation, and so on. These modules achieve the functions: fingering out the location of the cabin, registering the instructions from the cabin and the station hall, choosing the direction and the station of elevator follow these instructions, operating elevator and door automatically, and other functions. Simultaneously,this controller uses the design and development system of Kingview and the RS-485 concentration line which achieves the communication between PC and PLC to complete the remote monitor from PC to the elevator which is based on PLC.
