摘　　要：软件PLC技术是工业自动化领域兴起的一项基于PC的控制技术。结合数控系统用户实际需求,同时为了减少用户在使用产品上的差异,在Windows平台上设计实现了基于IEC61131-3标准的软件PLC梯形图开发系统。首先介绍了系统整体结构设计,主要模块包括梯形图编辑、语法检查、梯形图向文本化指令表语言的转换、指令表程序的编译,接着详细介绍了各个模块的实现方法,并用实例验证了开发系统的正确性,从而保证梯形图程序经过转换和编译过程后得到预期的目标代码。Soft PLC technology is a new control technology based on PC in industrial automation. In consideration of the requirement of the users of computerized numerical control system, and to reduce margins in product usage, the soft PLC ladder diagram development system based on IEC61131-3 standard is designed and implemented on Windows operating system. Firstly, the global logical structure of the system is devised, including ladder diagram editting, syntax checking, conversion from ladder diagram program to instruction list language program and compilation of the instruction list language program. Secondly, the concrete method to implement every module is presented. Finally, the correctness of the system is tested and validated by examples. As a result, the correctness ensures that the expected object code is obtained after conversion and compilation of the ladder diagram program.
