摘　　要：近几年随着网络软件开发技术越来越成熟,网络软件的开发与设计变得非常重要。传统工业控制领域,上位机基本上都使用控制器配套的组态软件,这种方式往往价格昂贵,并且通信协议不公开而受到限制,不适合许多低需求和高灵活度的企业,因此自主开发上位机软件变得非常有必要。在VS2013 IDE编程环境下,利用MFC封装的CSocket类,开发了基于ModbusTCP协议的上位机基础通讯软件,用来和ABB AC500系列PLC进行以太网通讯。In recent years,as network software development technology become more and more mature,the development and design of network software become very significant.In the field of traditional industrial control,the upper computer basically uses the configuration software provided by the controller,which will spend more money and the communication protocol is not public.It will not suitable for many low demand and highly flexible enterprises.Thus it gonna be necessary to design a upper computer software by independent development.This article is in the VS2013 IDE programming environment,using the CSocket class packaged by the MFC,develop the upper computer communication software base on ModbusTCP protocol.It will be used to communicate with the series of ABB AC500 PLC.
