由于各PLC厂家产品在指令系统上的差异及编程方法上用户要求不同，近年来IEC制订了基于Windows的编程语言标准IEC年IEC颁布可编程序控制器的国际标准IEC1131)，它规定了指令表(IL)、梯形图(LD)、顺序功能图(SFC)、功能块图(FBD)、结构化文本(ST)五种编程语言。这包括了文本化编程(IL、ST)和图形编程(LD、FBD)两个方面，而SFC则在两类编程语言中均可使用。IEC技术委员会(TC65)进来开展了 IEC61499项目，将IEC进行了扩展，它是针对通过通信网络互联的模块化分布系统的体系结构的标准，将对IEC有所改善。这是以数字技术为基础的可编程序逻辑控制装置在高层次上走向开放性的标准化文件，是PLC发展的一大趋势。
