在分布式控制系统设计中，现场控制器与监控站（上位机）的数据通信是其重要的组成部分，而ＡＲＣｎｅｔ网络在以工业ＰＣ为基础的分布式控制系统通信中承担了主要作用。介绍了ＡＲＣｎｅｔ工业网络结构与数据包的发送、接收及软件实现方法。其单元制机组汽温过程应用结果表明，ＡＲＣｎｅｔ工业网络具有理想的实时性与可靠性。
In the design of distributed control system, data communication between field controller and monitoring station (host computer) is an important part. ARCnet network plays a major role in industrial PC-based distributed control system communication. Introduced the ARCnet industrial network structure and data packet sending, receiving and software implementation. The results of the application of unit temperature process show that ARCnet industrial network has ideal real-time and reliability.
