內容提要 
PLC作為新一代的工業控制器，已經廣泛應用于各個領域的控制系統。隨著社會的不斷發展，樓房越來越高，而電梯成為了高層樓房的必須設備。電梯從手柄開關操縱電梯、按鈕控制電梯發展到了現在的群控電梯，為高層運輸做出了不可磨滅的貢獻。
在設計中我具體的講敘了利用PLC控制電梯的硬件系統和軟件系統的設計過程，列出了主要的硬件電路并選擇合適電氣元件，分析了主要輸入輸出點的作用。本設計選用三菱公司FX系列中的及其擴展單元PLC來控制電梯的運行。在PLC的電梯控制系統中,電梯的運行都是通過控制軟件來實現的。由于樓層較多，本設計采用變換的方法，當把十六層分為單數層和雙數層來控制。為了使控制軟件和電梯的運行動作有較好的對應關系，電梯的軟件控制程序主要分為樓層的呼叫信號記憶、開關門控制、速度變換程序、顯示程序等，各司其職，對電梯的運行進行控制。

Summary
PLC（Programmable Logic Controller）has been widely applied for control systems of many demesnes as a new generational industry controller. Along with society's unceasing development, the building is more and more high, but the elevator became the high level building to have the equipment. After humanity's more than centuries unremitting endeavors, the elevator already from the handle switch operation elevator, the push-button control elevator develops to the present group control elevator, has made the indelible contribution for the high level transportation.
  In the paper, I specifically recount the design process of hardware and software about PLC control elevator, listing the main hardware circuit and it also analyzes the using function of the main output points. This system is a design to use Mitsubishi FX2N-128MR and expanding unit PLC to control a sixteen floor simulation model. In the PLC controlling elevator system, running of elevator achieve through software. As floors more and more, the design uses method of transform, when the 16-divided into single-and double the number of floors to control. By the control software elevator can come true its function, to have a better correspondence relationship between control software and the action of elevator, I divide the control software several parts: calling program、switch door program、transform speed program、display program of floor and so on. They play to control elevator working correctly.
