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。国际电工委员会(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。
上世纪80年代至90年代中期,是PLC发展**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得到大幅度提高,PLC逐渐进入过程控制领域,在某些应用上取代了在过程控制领域处于统治地位的DCS系统。
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。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。
