基于MDI应用程序的软PLC仿真模块的研究与实现

Implementation of Instruction List Editor Module of SoftPLC Based on MDI Application

提出了一种在VC多文档应用程序基础之上实现仿真模块的方法。该模块主要实现了以开发系统编辑的梯形图程序为对象的程序仿真,并给出形象的仿真结果。其优点是数据处理方法和程序结构相对简单,并且充分利用了C++语言中类继承的特性,同时也为软PLC的程序检查奠定了基础。

This paper presents an implementation of the simulation module based on VC multi-document application. The module is the main achievement of the development ladder program editing system sim- ulation program, and gives the image of the simulation results. The advantage is that data processing method and program structure is relatively simple, and takes full advantage of the characteristics of class inherits in the C ＋ ＋ language, but also laid the foundation for the soft-PLC program to check.
