摘　　要：基于IEC61131.3标准,在嵌入式平台上设计并实现了软PLC梯形图编译系统。介绍了系统的结构设计,包括梯形图编辑器模块、语法检查模块、梯形图指令表转换模块以及指令表的生成过程,重点介绍了生成微处理器对应的目标代码的方法。用实例验证了开发系统的正确性,确保设计的梯形图程序能够正确的被转换和编译。Soft PLC ladder based on IEC61131.3 standard development system were designed and implemented on the embedded platform. First introduced the structural design of the system, including the ladder editor, syntax checking, ladder diagram translate to instruction list, and instruction list compilation process, in particular, is to introduce how to generate the object code corresponding to the MCU. In addition, using examples to verify the correctness of the development system, to ensure access to the desired object code after the ladder program has been translated and compiled.
