This product is flexible in application and can 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 be connected to the dual redundant bus system; When point-to-point network is adopted, the network segment of two PROFIBUS DP buses can be connected through optical fiber; PROFIBUS DP bus connection of multiple network segments is realized on the optical fiber bus with double optical port chain network (200); At the same time, this product adopts double optical ports to realize the redundancy function of double fiber ring network. When an optical fiber fails, the system will rebuild the network link within 10ms to ensure the normal communication of the system and realize the self-healing protection function of signal transmission. After the network fault is eliminated, the system will automatically recover; This series of products adopts the proprietary ring network protocol CI ring developed by the company, which does not need to be set up or the root node, and quickly completes the looping and de looping functions of the network. This series of products is plug and play, does not need to be configured, and greatly simplifies the user's installation and debugging process.
