微机局域网存取Deltav DCS实时数据的低成本实现方法

Implementation method of PC LAN accessing Deltav DCS real-time data with low cost

随着计算机技术与控制技术的不断发展 ,分布式控制系统 (DCS)越来越多地被应用于过程控制工业领域。介绍了在没有 OPC Sever模块的情况下 ,微机局域网 (PC L AN)上存取 Fisher- Rosemount公司的 Deltav DCS实时数据的实现方法。重点讨论了通讯系统结构与实施方法、Visual C++6 .0下的程序编制方法与技巧。实践表明 ,该方法数据传输可靠 。

With the development of computer and control technology, more and more DCS are applied in process control field. Without OPC Sever module, the implementation method of Deltav DCS real time data of Fisher Rosemount company in the LAN of computer( PC LAN) was introduced, not only the structure of communication system but also the procedure preparing method and especially skill under Visual C ++ 6.0 were discussed. The results indicate that the method is reliable in data transmission, and with low costs.
