Network topology structure

The application of PROFIBUS fiber optic repeaters is flexible, and can achieve point-to-point networking, chain network, star network, redundant dual network, and fiber optic ring network self-healing protection. Logically independent dual bus electrical interface, capable of backup of electrical interfaces and single device access to dual redundant bus systems; Point to point connection enables the connection of two Profibus DP bus segments through optical fibers; Implement multi segment Profibus DP bus connection on the fiber optic bus of the dual optical port chain network. At the same time, this series adopts dual optical ports to achieve dual fiber ring network redundancy function. When a fiber optic failure occurs in a certain area, the system will rebuild the network link within 10ms to ensure normal communication of the system and achieve self-healing protection function for signal transmission. This series adopts our company's self-developed proprietary ring network protocol Ci ring, which does not require settings and quickly completes the network's ring formation and ring removal functions. It is plug and play, does not require configuration, and greatly simplifies the installation and debugging process for users.
