改造DeviceNet总线电源减少网络关闭故障

Transformation of DeviceNet Bus Power to Reduce Failure of Network Shutdown

DeviceNet是CAN(Control Area Network)开放式的设备网络,他高度实现了分布控制的解决方案,是优于框架I/O模块,用于底层现场设备的网络,主要用来连接I/O适配器、智能传感器、驱动通讯等设备,产品实现数据交换的无缝连接,他的拓扑结构也是比较自由的。通常是主干线施工时能省去现场大量的控制连接导线,但是一旦发生故障,影响面大,判断故障点困难。

DeviceNet is an open CAN （Control Area Network） network which implements a high degree of distributed control solution for the bottom field device network mainly used for connecting I/O adapters, intelligent sensors and driving communication equipment, to achieve seamless data exchange between products with relatively free topological structure. Usually the main line construction can save a lot of control connecting wire with DeviceNet, but it＇s difficult to judge the fault point in case of failure.
