摘　　要：在Visual Basic基础上,利用动态数据交换和TCP/IP通信技术,研究了组态王与以太网接口的智能仪表之间的通信问题。并编写了上位机与智能仪表之间的TCP/IP通信程序以及组态王与VB之间的DDE程序。解决了组态王与带有以太网接口的智能仪表之间的通信问题,为组态王扩展驱动程序提供了一种新方法,实现组态王对以太网接口智能仪表的实时访问。In this paper, making use of dynamic data exchange and technology of TCP/IP communication, the method of data exchange between King-view and intelligent instrument with Ethernet port is researched on the basis of VB. And TCP/IP communication program between PC computer and intelligent instrument with Ethernet port and dynamic data exchange program between VB and King-view platform are written. The problem of communication between King-view and intelligent instruments is worked out. And a new way of expanding the library of driver of King-view is offered. In addition, the real time access to intelligent instrument with Ethernet port is implemented.
