DP/AS-I网关的开发及其在电控系统中的应用

Development of DP/AS-I Gateway and the Application in the Electrical Control System

针对某些场合会出现在一个现场总线系统中需要实现跨不同总线的信息传递与共享的情况,介绍了实现两种不同总线之间的连接的DP/AS-Ⅰ网关的开发,具体阐述了基于Profibus从站和AS-Ⅰ主站的软、硬件设计及DP/AS-Ⅰ网关在电控系统中的应用。

In a fieldbus system, the information should be transferred and shared by crossing the different fieldbus. The DP/AS-I gateway which realizes the connection of two kinds of different fieldbus was introduced. The hardware and software design of the Profibus slave and AS-I master was analyzed. And the application of the gateway in the electrical control system was introduced.
