可编程控制器PLC是一种专门为在工业环境下应用而设计的数字运算操作的电子装置。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，控制各种类型的机械或生产过程。PLC及其有关的外围设备都应该按易于与工业控制系统形成一个整体，易于扩展其功能的原则而设计

PLC即可编程控制器（Programmable logic Controller，是指以计算机技术为基础的新型工业控制装置。在1987年电工委员会（International Electrical Committee）颁布的PLC标准草案中对PLC做了如下定义：  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  PLC是一种专门为在工业环境下应用而设计的数字运算操作的电子装置。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，控制各种类型的机械或生产过程。PLC及其有关的外围设备都应该按易于与工业控制系统形成一个整体，易于扩展其功能的原则而设计。  电工委员会(IEC)在其标准中将PLC定义为:  「可程式逻辑控制器是一种数位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。可程式逻辑控制器及  其有关外部设备，都按易于与工业控制系统联成一个整体，易于扩充其功能的原则设计。」  PLC的特点  2.1可靠性高，抗*力强  高可靠性是电气控制设备的关键性能。PLC由于采用现代大规模集成电路技术，采用严格的生产工艺制造，内部电路采取了*的抗干扰技术，具有很高的可靠性。例如三菱公司生产的F系列PLC平均*时间高达30万小时。一些使用冗余CPU的PLC的平均*工作时间则更长。从PLC的机外电路来说，使用PLC构成控制系统，和同等规模的继电接触器系统相比，电气接线及开关接点已减少到数百甚至数千分之一，故障也就大大降低。此外，PLC带有硬件故障自我检测功能，出现故障时可及时发出警报信息。在应用软件中，应用者还可以编入外围器件的故障自诊断程序，使系统中除PLC以外的电路及设备也获得故障自诊断保护。这样，整个系统具有*的可靠性也就不奇怪了。  2.2配套齐全，功能完善，适用性强  PLC发展到今天，已经形成了大、中、小各种规模的系列化产品。可以用于各种规模的工业控制场合。除了逻辑处理功能以外，现代PLC大多具有完善的数据运算能力，可用于各种数字控制领域。近年来PLC的功能单元大量涌现，使PLC渗透到了位置控制、温度控制、CNC等各种工业控制中。加上PLC通信能力的增强及人机界面技术的发展，使用PLC组成各种控制系统变得非常容易。  2.3易学易用，深受工程技术人员欢迎  PLC作为通用工业控制计算机，是面向工矿企业的工控设备。它接口容易，编程语言易于为工程技术人员接受。梯形图语言的图形符号与表达方式和继电器电路图相当接近，只用PLC的少量开关量逻辑控制指令就可以方便地实现继电器电路的功能。为不熟悉电子电路、不懂计算机原理和汇编语言的人使用计算机从事工业控制打开了方便之门。  2.4系统的设计、建造工作量小，维护方便，容易改造  PLC用存储逻辑代替接线逻辑，大大减少了控制设备外部的接线，使控制系统设计及建造的周期大为缩短，同时维护也变得容易起来。更重要的是使同一设备经过改变程序改变生产过程成为可能。这很适合多品种、小批量的生产场合。  2.5体积小，重量轻，能耗低  以超小型PLC为例，新近出产的品种底部尺寸小于100mm，重量小于150g，功耗仅数瓦。由于体积小很容易装入机械内部，是实现机电一体化的理想控制设备。

先学会看梯形图，学会电工基本电路，这都是基本，买几本入门到精通的书，案例教程、视频教程、PLC实例，泡论坛学习看别人的程序学着去做，多向别人请教，无师自通唯有这样。你也可以参加PLC培训，在学校时我在技成培训网买视频学习，还是老师*的，你不妨去看下，是否符合你。
