20世纪60年代以前，汽车流水线的自动控制系统基本上都采用传统的继电器控制。在60年代初，美国汽车制造业竞争越发激烈，而汽车的每一次更新的周期越来越短，这样对汽车流水线的自动控制系统更新就越来越频繁，原来的继电器控制就需要经常地重新设计和安装，从而延缓了汽车的更新时间。所以人们就想能有一种通用性和灵活性较强的控制系统来替代原有的继电器控制系统。

PLC在食品、制造和冶金等其他工业部门相继得到了应用。1971年，日本引进了这项技术，并开始生产自己的PLC。1973年，欧洲一些国家也研制出了自己的PLC。1974年，我国也开始仿照美国的PLC技术研制自己的PLC，终于在1977年研制出第一台具有实用价值的PLC

PLC是传统的继电器技术和计算机技术想结合的产物，所以在工业控制方面，它具有继电器控制或通过计算机所无法比拟的特点。

1、高可靠性

在硬件方面，由于采用性能优良的开关电源，并且对采用的器件进行严格的筛选，加上合理的系统结构，最后加固、简化安装，因此PLC具有很强的抗振动冲击的性能；无触点的半导体电路来完成大量的开关动作，就不会出现继电器控制系统中的器件老化、脱焊、触点电弧等问题；所有的输入/输出（I/O）接口都采用了光电隔离措施，使外部电路和PLC内部电路能有效的进行隔离；PLC采用模块式的结构，可以在其中一个模块出现故障时迅速地判断出故障的模块并进行更换，这样就能够尽量缩短系统维修的时间

在软件方面，PLC的监控定时器可用于监视执行用户程序的专用运算处理器的延迟，保证在程序出错和程序调试时，避免因程序错误而出现死循环；当CPU、电池、I/O口、通信等出现异常时，PLC的自诊断功能可以检测到这些错误，并采取相应的措施，以防止故障扩大；停电时，后备电池和正常工作时一样，进行对用户程序及动态数据的保护，确保信息不丢失CPU主要由运算器、控制器、寄存器及实现它们之间联系的数据、控制及状态总线构成，CPU单元还包括外围芯片、总线接口及有关电路。内存主要用于存储程序及数据，是PLC不可缺少的组成单元。
