基于VB的集散控制系统通信程序的设计

Communication Design of Distributed Control System Based on VB

介绍了集散控制系统的概念和用VisualBasic来开发集散控制系统通信程序的原因。阐述了用VisualBasic实现集散监控系统的各种通信功能(包括与下位机的通信、动态数据交换、网络通信和远程通信),给出了各种通讯实现的基本方法和应用实例。由此看出,VisualBasic语言具有简洁明了,编程效率高、开发周期短、网络功能强等特点。利用VB中的多种通信手段,可实现DCS的多种通信功能,尤其适用于自行开发中小型DCS的通讯监控软件。

?The concept of Distributed Control System(DCS) and the reason of using Visual Basic in the communication of DCS in the foreword are briefly introduced. The realization of communication functions of DCS with the application on VB(including the masterslave station Communication, Dynamic Data Exchange,Internet work Communication and Remote Communication) are presented in detail and it put forward the communication methods and the examples .
