Flexibilis Redundant Switch (FRS) is an innovative Layer-2 Ethernet switch IP core, supporting both High-Availability Seamless Redundancy (HSR) and Parallel Redundancy Protocol (PRP). This triple-speed switch operates on a gigabit full-duplex mode across all ports, making it a high-performing solution for Ethernet redundancy demands in industrial automation environments. The FRS IP core integrates transparent clock functionality based on the IEEE 1588 Precision Time Protocol (PTP), essential for time-sensitive networking.
As an FPGA implementation, FRS can be utilized in both gigabit and 100Mbps rings without the need for separate RedBox devices, which allows for streamlined and cost-effective setup. It supports various Ethernet interface types, including copper and fiber, and provides packet forwarding at wire-speed with advanced filtering and prioritization capabilities.
FRS can be employed in multitude configurations—from three to eight ports—suitable for diverse applications ranging from simple end-node connections to more complex network architectures. Its adaptability makes it an ideal choice for enhancing network reliability where time synchronization and redundancy are critical.
