摘要
FINS是欧姆龙公司开发的用于工业自动化控制网络的通信协议。主要描述了在以太网通信中使用的FINS/UDP协议的基本原理、Fins帧结构以及Fins指令。通过一个实例介绍了在Visual Basic 6.0中使用Winsocket,FinsGateway,SYSMAC Compolet控件编程来实现欧姆龙PLC和上位机以太网通信的三种方法。
FINS is a communication protocol developed by OMRON for the applications in industrial automation networks. In this paper, the basic principle of application of FINS/UDP protocol in Ethernet communication, as well as the Fins frame and Fins command are described. Three methods for realizing communication between OMRON PLC and a host, which use Winsocket, FinsGateway, and SYSMAC Compolet controls programming respectively in Visual Basic 6.0, are introduced by taking a practical example.
