基于MDI应用程序的软PLC指令表编辑模块的实现

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

文章提出了一种在VC多文档应用程序基础之上实现指令表编辑模块的方法。该模块主要包括指令表编辑器和程序输出窗口的开发,以及编辑器中数据的提取、交换、存储和输出。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程序的编译奠定了基础。

This paper presents an implementation of the Instruction List editor module based on VC multi- document application. This module includes the development of the Instruction List editor and program output window, as well as the extraction, exchange, storage and output of the data in the editor. 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 compilation of soft PLC program.
