摘 要
PLC英文全称Programmable Logic Controller ,中文全称为可编程逻辑控制器，定义是:一种数字运算操作的电子系统，专为在工业环境应用而设计的。它采用一类可编程的存储器，用于其内部存储程序，执行逻辑运算,顺序控制，定时，计数与算术操作等面向用户的指令，并通过数字或模拟式输入/输出控制各种类型的机械或生产过程.PLC是可编程逻辑电路，也是一种和硬件结合很紧密的语言，在半导体方面有很重要的应用，可以说有半导体的地方就有PLC
2001年我国机械工业成为工业发展新亮点，总产值比上年增长17.15%，汽车产量为世界前10位，机床产量为世界第5位。机械工业利润增长 33.35%，占整个工业新增利润六成多。出口同样出现可喜的增长。现在机械工业提出要实施网络化，对这一点，PLC从业人员应有清醒的认识，应对网络化的开放性、网络构成的性能/价格比和网络的可靠性、安全性、先进性上特别下功夫。

Abstract
PLC name in English Programmable Logic Controller, the Chinese called the programmable logic controller, the definition is: a digital computing operation of electronic systems, in industrial environments for applications. It uses a class of programmable memory, for its internal storage procedures, the implementation of logic operations, sequence control, timing, counting and arithmetic operations, such as user-oriented instruction, and digital or analog input / output control of all types the machinery or the production process. PLC is programmable logic circuits, and hardware is also a very strong combination of language, in the semiconductor has a very important application, is a place where there semiconductor PLC
China's machinery industry in 2001 to become a new bright spot for industrial development, GDP growth of 17.15 percent over the previous year, vehicle production for the world's top 10, the world machine tool production was 5. Machinery Industrial 33.35% profit growth, accounting for the entire industry additional60%more profits. Exports have also experienced an encouraging growth. Machine-building industry is now proposed to implement the network, and on this point, PLC should have a clear understanding of practitioners should be an open network, the network constitute the performance / price ratio and network reliability, security, advanced under the special Kung Fu.
