在北京地铁五号线项目设计和实施过程中,遇到的两个问题,一是多种总线协议标准共存,需要各种总线协议设备互连;二是供应商设备通信接口五花八门,需要统一连接到一种选定的工业通信网络及现场总线系统中。通过使用PROFIBUS总线桥可以方便的将多家第三方设备集成到PROFIBUS现场总线网络中,保证设备的实时监控和系统的可靠运行。 In Beijing Metro Line 5 project design and implementation process, the two problems encountered, first, a variety of bus protocol standards coexist, the need for a variety of bus protocol interconnection equipment; second is a wide range of supplier equipment communication interface, you need a unified connection To a selected industrial communications network and fieldbus systems. By using the PROFIBUS bus bridge, it is easy to integrate several third-party devices into the PROFIBUS fieldbus network to ensure the real-time monitoring of the equipment and the reliable operation of the system.
