1. 可编程控制器的定义
可编程控制器，简称PLC（Programmable logic Controller）,是指以计算机技术为基础的工业控制装置。在1987年国际电工委员会（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。”
2. PLC的特点
2.1可靠性高，抗干扰能力强
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平均无故障时间高达30万小时。一些使用冗余CPU的PLC的平均无故障工作时间则更长。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，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，整个系统具有极高的可靠性也就不奇怪了。
