Implement HSR/PRP with a Single Chip: SpeedChips XRS7000 Family

Flexibilis’ brand new product family is first of its kind in the world: An integrated circuit with which you can add HSR/PRP functionality to your device. This new chip series is called XRS7000 and is part of Arrow Electronics’ SpeedChips product family.

HSR and PRP are standardized redundancy protocols (IEC 62439-3 Clause 5 & 4) for wired Ethernet and provide zero-loss redundancy with no single point of failure. The aim of redundancy is to make fail-safe systems and HSR is currently the most efficient redundancy protocol available for Ethernet.

There are two different chips available which both have HSR and PRP support: XRS7003 (three ports) and XRS7004 (four ports). The chips also include IEEE 1588v2 Precision Time Protocol (PTP) transparent clock functionality. They can be used for example in industrial automation, motion control, substation automation, vehicle communication and networking equipment.

FES 3.0 Combines FES, FRS and FDS into a Single IP Core

The new version of FES, FRS and FDS combines these three Flexibilis Ethernet IP Cores together into one core, called FES 3.0. FES 3.0 introduces the possibility to license selectable features.

The additional and licensable features include:

  • HSR
  • PRP
  • Static MAC table
  • Traffic Policing
  • Traffic Shaping
  • MACsec

Without any optional features FES 3.0 is a basic Ethernet switch core. The design variation of FES 3.0 that combines redundant networking features is called Flexibilis Redundant Switch (FRS), and the variation with Time-sensitive networking (TSN) features is called Flexibilis Deterministic Switch (FDS).

Compared to previous versions, new features include MACsec, new generics and improved HSR Mode X support. More detailed description of FES 3.0 can be found in its manual: FES Manual

FES 3.0 has several changes compared to the previous versions FRS 2.9.4 and FES. Please contact us if you need help in migrating from FRS 2.9.4 / FES to FES 3.0.

Best in Class Industrial Ethernet: Flexibilis and ABB Distribution Automation Protection Relays

The modern Protection Relay has high communication demands, the Protection Relays being often connected to one another in ring or star topologies. The Relays exchange high amounts of data at extreme latency requirements: Relays can communicate with one another exchanging measurement results according to the IEC 61850 9-2 Protocol, and the results need to be correlated in time. The Relay connections need to be reliable and redundant, HSR (High-availability Seamless Redundancy) and PRP (Parallel Redundancy Protocol) are in use.

In implementing the communication solutions, ABB collaborates with Flexibilis. The co-operation is already of long standing, lasting more than a decade. A key component of the solution is the Flexibilis FRS IP block.

The co-operation has been very fruitful, and the results are available for everyone in the highly efficient and reliable communication implemented within the ABB Relion Series Relays. Both ABB and Flexibilis are highly satisfied with the mutual work done, and expect the co-operation to continue several years into the future.


HSR Standard Ed. 3 Introduces Mode X

Edition 3 of IEC 62439-3 has been approved on January 8th, 2016. IEC 62439-3 is the standard for High-availability Seamless Redundancy (HSR) and Parallel Redundancy Protocol (PRP).

Flexibilis Redundant Switch (FRS) supports the new edition, including the HSR Mode X it introduces. In HSR Mode X, nodes discard the duplicates in opposite direction. This reduces the amount of network load caused by the multicasts to about half and frees resources for other uses.

FRS Optimized in New Version 2.9.1

New version of Flexibilis Redundant Switch (FRS) is now available, and can be downloaded from here: In version 2.9.1 of the IP core, memory and logic usage have been optimized and issues fixed. Also version 2.9.2 is already out, it adjusts management trailer handling for QuadBox.

The reference design version 2.9.1 changes the design to match the newest IP core version. Also supervision stack has been updated.

FRS Now Has Cut-through

New version of Flexibilis Redundant Switch (FRS) has been released this week. The most significant improvement is that the switch now has cut-through functionality, in addition to store-and-forward. You can freely choose between these two, whichever suits your system better.

Cut-through is a packet forwarding method in which the switch starts to forward the packet before it is fully received. This lowers latency in a non-congested network. With store-and-forward the packet is fully received before it is forwarded, and it is more reliable especially if there are high error rates.
