在PLC诞生之前，继电器控制系统已广泛应用于工业生产的各个领域，起着不可替代的作用。随着生产规模的逐步扩大，继电器控制系统已越来越难以适应现代工业生产的要求。继电器控制系统通常是针对某一固定的动作顺序或生产工艺而设计，他的控制功能也局限于逻辑控制、定时、计数等一些简单的控制，一旦动作顺序或生产工艺发生变化，就必须重新进行设计、布线、装配和调试，造成时间和资金的严重浪费。继电器控制系统体积大、耗电多、可靠性差、寿命短、运行速度慢、适应性差。为了改变这一现状，1968年美国zui大的汽车制造商通用汽车公司（GM），为了适应汽车型号不断更新的需求，并能在竞争激烈的汽车工业中占有优势，提出要研制一种新型的工业控制装置来取代继电器控制装置，为此，拟定了10项公开招标的技术要求，即： 
            1、 编程简单，可在现场修改程序
            2、 维护方便，是插件式
            3 、可靠性高于继电器控制柜
            4 、体积小于继电器控制柜
            5 、可将数据直接送入管理计算机
            6 、在成本上可与继电器控制柜竞争            
            7、输入可以是交流115V
            8、输出可以是交流115V，2A以上，可直接驱动电磁阀等
            9、 在扩展时，原有系统只要很小变更
           10 、用户程序存储器容量至少能扩展到4K

目前，随着大规模和超大规模集成电路等微电子技术的发展，PLC已由zui初一位机发展到现在的以16位和32位微处理器构成的微机化PC，而且实现了多处理器的多通道处理。如今，PLC技术已非常成熟，不仅控制功能增强，功耗和体积减小，成本下降，可靠性提高，编程和故障检测更为灵活方便，而且随着远程I/O和通信网络、数据处理以及图象显示的发展，使PLC向用于连续生产过程控制的方向发展，成为实现工业生产自动化的一大支柱。
    现在，世界上有200多家PLC生产厂家，400多品种的PLC产品，按地域可分成美国、欧洲、和日本等三个流派产品，各流派PLC产品都各具特色。其中，美国是PLC生产大国，有100多家PLC厂商，*的有A-B公司、通用电气（GE）公司、*康（MODICON）公司。欧洲PLC产品主要制造商有德国的西门子（SIEMENS）公司、AEG公司、法国的TE公司。日本有许多PLC制造商，如三菱、欧姆龙、松下、富士等，韩国的三星（SAMSUNG）、LG等，这些生产厂家的产品占有80%以上的PLC*。
