Now the elevator control system mainly has three ways: the relay control system, PLC control system, microcomputer control system. PLC control system with high luck reliability, maintenance convenience, strong anti-interference, design and debugging cycle short advantages, people pay more and more attention, has become the elevator control system in the use of most of the control method. In this paper, the structure of the elevator and on the basis of structure and working principle of the programmable controller, for the six store elevator, using Siemens S7-200 programmable controller, the design of elevator control system, including car instruction and the hall call information for the registration and eliminate, elevator layer and set to, the elevator door switch operation, elevator control, elevator to control layer, the car and each layer of call instruction records, the elevator running direction and layer selection control, elevator up and down and automatic opening and closing the door, elevator refers to the layer control, and other functions.Key words: six layer elevator; control system; programmable controller; Key words: six layer elevator; control system; programmable controller; 目　　录 TOC \o 1-3 \h \z HYPERLINK \l _Toc27277 摘　　要 PAGEREF _Toc27277 1 HYPERLINK \l _Toc1845 Abstract PAGEREF _Toc1845 1 HYPERLINK \l _Toc12677 绪论 PAGEREF _Toc12677 1 HYPERLINK \l _T
