But the elevator takes the modern high-rise construction the vertical transportation vehicle, with people's life close related, along with the people to its request's enhancement, the elevator obtained the fast development, its logical control also replaces the original black-white control by PLC. This article uses PLC to carry on the control to the elevator, through the reasonable choice and the design, raised elevator's control level, and improved the elevator movement comfort, enabled the elevator to achieve the more ideal control effect. This article mainly introduced four elevator's PLC control system overall project designs, the design process, the composition, have listed elevator's control trapezoidal chart. And has given the system composition diagram, in the analysis, in the processing random signal logical relation's foundation, proposed the PLC programming method. key word: Four elevators; S7-200PLC; Control system, trapezoidal chart
