摘 要
 西门子公司生产的LOGO！通用逻辑控制模块是一种新型的可编程序逻辑控制器，它采用可以编制程序的存储器，用来在其内部存储执行逻辑运算、顺序运算、计时、计数和算术运算等操作的指令，并能通过数字式或模拟式的输入和输出，控制各类的机械或生产过程。LOGO！的可靠性、易操作性和灵活性使它成为了新一代工业自动化产品中的佼佼者，并在控制工程网2006/2007年度最佳产品奖颁奖典礼上获得了离散控制与传感器类产品一等奖。我学习LOGO！的程序设计并以此作为我的毕业设计也正是因为它的出色性能和深厚潜力，让我产生了浓厚的兴趣。我在完成毕业设计的这几个月里学习了LOGO！本身的许多基本知识和应用，并且通过其配套的LOGO！Soft Comfort编程软件自己动手设计出了几个比较有意思的程序，还借此机会了解了PLC的一些相关知识以及国内外发展情况，对这一行业的未来发展也有了更进一步的认识。这篇毕业论文就是对我以上所学的一个总结，主要内容包括：（1）PLC的现状和发展趋势。（2）西门子LOGO！简介。（3）LOGO！的程序设计。

Abstract
 LOGO！current logic control module produced by Siemens Automation & Drives Group is a new-style programmable logic controller . It adopts the programmable memorizer to store and execute the operational instructions of Boolean calculation, sequence calculation, time, count and arithmetic calculation etc. inside, and controls many kinds of the mechanical and producing course by digital or simulative import and export. The dependability, operability and flexibility of LOGO! makes it become the outstanding one of the new-style industry autoimmunization production , and it wins the first award of the discrete control and sensor production in the best production award ceremony in the year of 2006/2007 of control engineering web . I study the programmer of LOGO! and research it for my graduate designing because of its excellent capability and infinite potential , which makes me become deeply interested in it . I studied a lot of basic knowledge and applications of LOGO! in the process of the graduate designing , and used its match able “LOGO! Soft Comfort” programmer software to work out some interesting program by myself. Moreover, I learned some correlative knowledge of PLC and its internal and overseas developmental situation, and knew more about the future development of this industry by this chance. This thesis is the summary of the above content I learned. The main content includes: (1) the present status and the developmental trend of PLC. (2)The brief instruction of Siemens LOGO!. (3)The programmer of LOGO! .
