摘　　要：本文简述了PLC功能块图FBD的基本概念、功能和编程方法。针对功能块图FBD编程系统的设计要求,基于IEC61131-3国际标准制定的编程规则,采用面向对象的方法,设计出了一套全新的完整实用的数据结构。同时介绍了功能块图编程系统的设计方案及其基于VC++集成开发环境的方案实现。The basic conception.function and programming method of function block diagram （FBD） were summarized. According to the requirement of the FBD programming system and the IEC61131-3 international standard, a suit of appropriate data structure was designed based on object-oriented programming. The design scheme and the implementation based on VC ＋ ＋ integrated development environment for FBD programming system was also introduced in this paper.
