产品详情资料
诸如NIU之类的I/O设备可以连接到这对总线中的一条总线,也可以连接到两条总线。连接到两条总线的设备实际上一次只能在一条总线上通信。在备用总线可用于通信之前,必须进行总线切换,并且设备必须与备用总线上的总线控制器“登录”。NIU包含一个内置的总线切换继电器,用于切换双总线系统中的总线。具有此功能的其他类型的设备包括现场控制BIU、总线交换模块和90-70系列远程I/O扫描器模块。这是可以直接连接到两条冗余总线电缆的设备类型。NIU不能用作总线存根的BSM控制器。其他设备不能位于NIU下游的存根上。冗余总线配置许多不同的冗余总线配置是可能的。下面介绍了使用带有冗余总线的NIU的三种基本方法NIU可以直接安装在双总线对的两根电缆上。NIU被配置为除了执行其正常功能之外,还作为总线交换设备操作。I/O devices such as the NIU may be connected to either one bus of the pair, or to both. A device that is connected to both busses actually communicates on only one bus at a time. Before the alternate bus can be used for communications, a bus switchover must occur and the device must “log in” with the Bus Controller(s) on the alternate bus. The NIU contains a built-in bus switching relay that is used to switch busses in a dual bus system. Other types of devices with this capability are Field Control BIUs, Bus Switching Modules and Series 90-70 Remote I/O Scanner modules. These are the only types of devices that can be directly connected to both redundant bus cables. An NIU cannot be used as the BSM Controller for a bus stub. Other devices cannot be located on a stub downstream of an NIU. Redundant Bus Configurations Many different redundant bus configurations are possible. Three basic ways of using an NIU with a redundant bus are described below. „ An NIU can be installed directly on both cables of the dual bus pair. The NIU is configured to operate as a bus switching device in addition to performing its normal functions.
