Dual optical port design:Dual optical ports are used to realize the dual fiber ring network redundancy function.When a certain optical fiber fails,the system can rebuild the network link within 10ms to ensure the normal communication of the system and realize the self-healing protection function of signal transmission.

Proprietary ring network protocol:The company’s self-developed proprietary ring network protocol Ci-ring is used.There is no need to set the root node,and the network ring and de-ring functions can be completed quickly.

Plug and play:No configuration is required,which greatly simplifies the user’s installation and debugging process.

2.Performance indicators

Data electrical interface:9-pin Sub_D jack connector,the pin definition conforms to the protocol specification of Profibus DP.

Communication rate:supports multiple communication rates,including 9.6kBit/s,19.2 kBit/s,45.45kBit/s,etc.,up to 12MBit/s.

Signal delay:electrical port signal delay≤11Bit,optical port signal delay≤1.6us/node.
