IFIX读取远程OPCServer中的数据

IFIX Read the Data in the Remote OPCServer

随着计算机技术,通信技术,集成电路技术、智能传感技术及控制技术的发展,控制技术开始融合网络低层通信技术,实现了一定范围内的控制要求.这一切都要求我们对控制网络系统和远程通信技术进行研究,以便顺应控制网络与信息网络集成的趋势,组建企业信息网络系统,借助Internet或其他网络,对企业现场生产过程信息进行远程监控.国外对控制网络系统的远程监视与控制研究的较多,现在国外最先进的控制网络技术是以太网作为现场控制总线现场总线建立工业控制界的分布式开放系统与之相适应,为了满足工业控制数据交换的要求,现场总线与系统应用之间的接口也在追求一种标准化,如是OPC技术应运而生,本文介绍IFIX如何读取远程OPCServer中的数据.

With the computer technology, communications technology, integrated circuit technology, smart sensor technology and control technology, control technology converged networks began low-level communications technology to achieve a range of control requirements.All this requires us to control network system and telecommunication technology research,in order to comply with the control network and information network integration trend,the formation of enterprise information network system,with Internet or other network,on-site production process information enterprise remote monitoring.Control network systems abroad remote monitoring and control of the more,now the most advanced technology is the ethemet control network control bus as Fieldbus field establishment of industrial control field corresponding distributed open systems,in order to meet industry control data exchange requirements,field bus interfaces between applications and systems are also pursuing a standardized case of OPC technology came into being,this article describes how to read a remote OPCServer IFIX data.
