一个总长11km的快速以太网在南威尔士建成,它用于连接规模庞大的BP化工厂Baglan Bay地区中6个分散的区域。这个新的网络实现了一个真正的分布式控制系统,它在HMI和生产基地之间传送监督数据和管理命令。在HMI里要生成对生产基地的报警、趋势、诊断分析和日常管理。建设此快速以太网的计划书中把网络的可靠性和适应性放在了首要的位置。在部分化工生产车间停产和取消以后,BP化工厂Baglan Bay地区正在进行主要的重建工作。原有的生产车间中仅有生产异丙基乙醇的车间被保留下来。
A 11km Fast Ethernet network was set up in South Wales to connect six discrete areas in the large BP chemical plant in Baglan Bay. This new network enables a truly distributed control system that communicates supervisory data and management commands between the HMI and the production site. In the HMI to generate the alarm on the production base, trends, diagnostic analysis and daily management. The plan to build this Fast Ethernet puts the reliability and adaptability of the network at the top of the list. Following the closure and cancellation of some of the chemical production plants, major rebuilding efforts are under way in BP’s Baglan Bay area. The only production workshop in the original production of isopropyl alcohol plant was retained.
