本文分享了IEC61131-3标准中的数据类型、编程语言、POU、实例化等几个概念,并就IEC61131-3将标准编程技术和当代编程语言的优点结合起来的使用体会做了分析。研华PAC符合IEC61131-3编程语言标准及支持实时多任务控制,而通过研华PAC在混凝土搅拌站控制系统上的应用,介绍了IEC61131-3标准编程、STD编写实用功能块、实时多任务等在实际工程中的应用优势。
This article shares IEC61131-3 standard data types, programming languages, POU, instance of several concepts, and IEC61131-3 will standard programming techniques and the advantages of contemporary programming language to do with the use of experience made an analysis. Advantech PAC accords with IEC61131-3 programming language standard and supports real-time multitask control, but through Advantech PAC in the concrete mixing plant control system application, introduced IEC61131-3 standard programming, STD writes the practical function block, real-time multitasking and so on actual Application advantages in engineering.
