在工业生产中，大量的开关量顺序控制，它按照逻辑条件进行顺序，并按照逻辑关系进行连锁保护的控制，及大量离散量的数据采集。上，这些功能是通过气动或电气控制来实现的。1968年美国GM（通用汽车）公司提出取代继电气控制装置的要求，第二年，美国数字公司研制出了基于集成电路和电子技术的控制装置，采用程序化的手段应用于电气控制，这就是代可编程序控制器，称Programmable Controller（PC）。
个人计算机（简称PC）发展起来后，为了方便，也为了反映可编程控制器的功能特点，可编程序控制器定名为Programmable Logic Controller（PLC），现在，仍常常将PLC简称PC。
PLC的定义有许多种。电工会（IEC）对PLC的定义是：可编程控制器是一种数字运算操作的电子，专为在工业下应用而设计。它采用可编程序的存贮器，用来在其内部存贮执行逻辑运算、顺序控制、定时、计数和算术运算等操作的指令，并通过数字的、模拟的输入和输出，控制各种类型的机械或生产。可编程序控制器及其有关设备，都应按易于与工业控制形成一个整体，易于扩充其功能的原则设计。
上世纪80年代至90年代中期，是PLC发展快的时期，年增长率一直保持为30~40%。在这时期，PLC在处理模拟量能力、数字运算能力、人机接口能力和网络能力大幅度，PLC逐渐控制领域，在某些应用上取代了在控制领域处于统治地位的DCS。
PLC具有通用性强、使用方便、适应面广、可靠性高、抗能力强、编程简单等特点。PLC在工业自动化控制特别是顺序控制中的地位，在可预见的将来，是无法取代的。
