Description

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。

自标准颁布之后，并没有产生很大的影响。原因在于：中国不存在真正像样的PLC制造业；在中国国内有影响的PLC品牌并不积极推介；包括该标准的主管部门在内，很少有组织的推进活动。直到1998年以后，由于IEC 61131-3在国际控制业界的影响越来越大，在中国国内有影响的PLC品牌开始提及自身品牌符合或兼容IEC 61131-3；若干新推出的DCS系统也公开宣称，符合或兼容IEC 61131-3。

人们才关注这个标准。在有关杂志上有专文介绍该标准的制订背景、重要性、标准的主要内容。中国机电一体化技术应用协会组织翻译了两名德国作者Ｋarl-Heinz John和Miachael Tiegelkamp写的专著：”IEC 61131-3：工业自动化系统的程序编制”。现已由该协会内部发行。近，中国机电一体化技术应用协会（CAMETA）与以开发基于IEC 61131-3的编程系统称著的德国KW公司远东总经理Robert Champoud先生合作，组织协调有关IEC 61131项目的研讨会活动，得到Siemens、Phoenix、富士电机的大力支持。这对于促进它的推广，有着深远的意义。
