可编程控制器（PROGRAMMABLE CONTROLLER，简称PC）。与个人计算机的PC相区别，用PLC表示。
PLC是在传统的顺序控制器的基础上引入了微电子技术、计算机技术、自动控制技术和通讯技术而形成的一代新型工业控制装置，目的是用来取代继电器、执行逻辑、记时、计数等顺序控制功能，建立柔性的程控系统。国际电工委员会（IEC）颁布了对PLC的规定：可编程控制器是一种数字运算操作的电子系统，专为在工业环境下应用而设计。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过程。可编程序控制器及其有关设备，都应按易于与工业控制系统形成一个整体，易于扩充其功能的原则设计。
PLC具有通用性强、使用方便、适应面广、可靠性高、抗干扰能力强、编程简单等特点。可以预料：在工业控制领域中，PLC控制技术的应用必将形成世界潮流
PLC程序既有生产厂家的系统程序，又有用户自己开发的应用程序，系统程序提供运行平台，同时，还为PLC程序可靠运行及信息与信息转换进行必要的公共处理。用户程序由用户按控制要求设计。
