可编程序控制器,英文称Programmable Controller,简称PC。但由于PC容易和个人计算机(Personal Computer)混淆,故人们仍习惯地用PLC作为可编程序控制器的缩写。它是一个以微处理器为核心的数字运算操作的电子系统装置,专为在工业现场应用而设计,它采用可编程序的存储器,用以在其内部存储执行逻辑运算、顺序控制、定时/计数和算术运算等操作指令,并通过数字式或模拟式的输入、输出接口,控制各种类型的机械或生产过程。PLC是微机技术与传统的继电接触控制技术相结合的产物,它克服了继电接触控制系统中的机械触点的接线复杂、可靠性低、功耗高、通用性和灵活性差的缺点,充分利用了微处理器的优点,又照顾到现场电气操作维修人员的技能与习惯,特别是PLC的程序编制,不需要专门的计算机编程语言知识,而是采用了一套以继电器梯形图为基础的简单指令形式,使用户程序编制形象、直观、方便易学;调试与查错也都很方便。用户在购到所需的PLC后,只需按说明书的提示,做少量的接线和简易的用户程序编制工作,就可灵活方便地将PLC应用于生产实践

工业生产一般对控制设备的可靠性要求很高,并且要有很强的抗干扰能力。PLC能在恶劣的环境中可靠的工作,平均无故障时间达到数万小时以上,已被公认为*可靠的工业控制设备之一。
PLC本身具有较强的自诊断功能,保证硬件核心设备(CPU、存储器、I/O总线等)在正常情况下执行用户程序,一旦出现故障则立即给出出错信号,停止用户程序的执行,切断所有输出信号,等待修复。PLC的主要模块均采用大规模和超大规模集成电路,I/O系统设计有完善的通道保护与信号调理电路。在结构上对耐热、防潮、防尘、抗震等都有的考虑,在硬件上采用隔离,屏蔽、滤波、接地等抗干扰措施,在软件上采用数字滤波等措施。与继电器系统和通用计算机相比,PLC更能适应工业现场环境要求。

而且PLC里边设计出了计数器和计时器,这样避免使用麻烦的实物计时器和时间继电器,修改计数和计时值非常快捷方便,把以往传统继电器很难实现的时序逻辑控制做得非常。甚至有些老板担心客户不给钱,使用万年历设定一个时钟,运行到某年某月某日某时某分某秒,自动会停下部分功能来。
