使用DDE实现应用程序与Modbus协议连接

Link Windows Application With Modbus Protocol by DDE

由于用途、要求、生产厂商的不同,许多计算机应用系统之间存在着隔阂。比较典型的是工业控制系统和普通应用程序之间的数据通讯问题。本文介绍作者在实际的应用中,通过自己设计一个DDE数据传输模块来实现Windows应用程序与基于Modbus协议的工控系统之间的数据传输。

Owing to the difference in use,requirement and manufacturer,there are breaks among computer application systems.The most typical one is the data communication between control system and application.This paper provides a solution to link Windows application to a control system based on Modbus protocol with a DDE communication module designed by the writer.
