自1985年开始，小型PLC首先是三菱电机公司的MELSEC-F，通过非政府渠道进入中国市场。不到三、四年时间，小型PLC就形成了大面积的推广应用局面。1990年以后，Siemens、Allen Bradley以及其它品牌开始大举进入中国市场，占据中、大型的PLC的较大份额
由上简要回顾可知，PLC在中国已经形成了规模巨大的应用市场，但并未建立批量生产、有持续开发发展能力的PLC制造业。
应指出的是：
在国内，PLC的应用水平还是不低的，自主设计、系统集成和现场投运的能力，可以说与国际主流水平同步；
PLC的应用领域也很广泛，覆盖冶金、电力、化工、石油化工、机械、轻工、电子、电工、建材水泥等工业，以及现代农业机械和其它应用。近年来环保工业也有广泛应用，发展势头很猛。
在国内有一支庞大的PLC销售、服务、应用、系统集成队伍，遍布除西藏外的全国各地。
有充足的理由说：PLC在中国已成为工业控制的一种适用技术。因此，PLC、软PLC以及IEC 61131-3的发展，无可争辩地成了十分令人关注的事情。
IEC 61131国际标准在中国
1992年以后，可编程序控制器国际标准IEC 61131的各个部分陆续公布施行。中国的工业过程测量和控制标准化委员会按与IEC国际标准等效的原则，组织翻译出版工作。于1995年12月29日以GB/T 15969.1,15969.2,15969.3,15969.4颁布了PLC的国家标准。该标准只涉及IEC 61131的、第二、第三和第四部分，没有纳入1995年以后出版的第五部分通信、第七部分模糊控制编程软件工具、第八部分IEC 61131-3语言的实现导则。
