1756-CHBR module

This product is flexible and can be used to form a variety of optical fiber networks. The logic independent dual-bus electrical interface can realize the backup of the electrical interface or the single device can access the dual-redundant bus system: when the point-to-point network is used, the network segment of the two Profibus DP total money lines can be connected by optical fiber; The multi-network segment Frofibus DP bus connection (200) is realized on the optical fiber bus of the double optical port chain E network. This product uses dual optical ports to realize the redundancy function of dual-fiber ring network. When an optical fiber fails, the system will rebuild the network link > ensure the normal communication of the system within 10ms. The self-healing protection function for signal transmission will be realized, and the system will automatically recover after the network fault is removed. This series of products use the company's own research and development of the proprietary ring network protocol Ci - ing, do not need to set up. Do not need the root node, quickly complete the network ring and unring function, the series of products plug and play, no configuration, to a large extent, the user installation and debugging process simplified.
