Network interface for device-level ring networks uses priority channel technology

摘要

Innovasic's RapID platform network interface for industrial Ethernet connectivity supports high-performance device-level ring (DLR) networks. DLR is the fault recovery protocol endorsed by ODVA for network ring topologies, and can support beacon rates down to 100 (is enabling fault recovery and ring restore times of less than 10 ms. Participation in the DLR ring is transparent to any host processor or host application connected to the RapID platform. As with all protocol versions of the network interface, the EtherNet/IP version with DLR incorporates PriorityChannel technology, which eliminates the effects of network traffic loading and ensures real-time EtherNet/IP messages are always processed on-time.
