2 The Need for Redundant Data Communications In Automated Management Environments, like Power Systems management, reliable data transmission is crucial for safety and reliability. In these scenarios, network or device redundancy protocols play a vital role in the continuous operation of a service. All hardware and Software components of the Substation Automation system are designed and manufactured in such a way that they meet the high availability requirements. This means high reliability as well short down times. K. Brand, V. Lohmann and W. Wimmer, Substation Automation Handbook, UCA L, 2003

3 The SoCe Difference SoCe offers specialized design services and technology based on reconfigurable devices (FPGAs). SoCe solutions, IP Cores and SoPCs are implemented on FPGAs. They are focused on IEEE 1588 V2 Ethernet Based Systems Synchronization, and Reliable Ethernet (PRP and HSR IEC clauses 4 and 5). SoCe added value: We have developed efficient switching architectures optimized for these new protocols Our licensable IP Cores give you the option to implement these functionalities directly in an FPGA integrated into your own motherboards, or acquire an OEM version We have reference designs at your disposal, so that for a limited time you can test our functionalities in any Xillinx evaluation board before purchasing Our solutions are based on programmable and scalable technology; thus, you can upgrade the functionalities of your board if needed without any hardware change required SoCe technology will be present in the PRP/HSR Interoperability demo at the Cigre 2012 congress. One of the only 6 companies worldwide that will take part in HSR demo Under customer demand, we can offer reliability and robustness experimental analysis of your FPGA implementation (resilience against SEU effects, partial degradation, etc.) for reliability calculations, safety analysis and subsequent certifications (IEC and IEC 61508: Functional Safety of E/E/PE Safety Related Systems) SoCe is a Member Level partner of the Xilinx Alliance Program. For all of our solutions, the usage of market tested, high quality and affordable FPGAs by Xilinx allow us to offer standard and customized PRP, HSR and PTPv2 solutions that provide high reliability and accuracy at competitive prices We have partnered with IXXAT in Germany, to jointly provide the best solutions in the high availability, redundant and synchronized communications market

4 How HSR Provides Network Redundancy HSR provides redundancy by sending packets in both directions through a ring network. A simple HSR network consists of Doubly Attached Bridging Nodes, each having two Ethernet ports. A HSR capable node sends the same frame over both ports. A HSR capable destination node receives, in fault free state, two identical frames over both ports respectively within a certain interval. The first received frame is accepted while the duplicate is discarded. In case of an interruption in the ring, the frame will always be received through the other port. In an Electrical Substation scenario, HSR has been designed to meet the strict communications requirements set for Process bus in the IEC

5 GPS SCADA NCC NCC v PRPNet or HSR-PRP Switch IP v v v v PRP-1 ( Clause 4) Redundant Ethernet Network HSR-PRP Switch IP LAN A LAN B HSR-1 ( Clause 5) Ring Network Redbox HSR-1 ( Clause 5) Ring Network HSR-1 ( Clause 5) Ring Network HASARNet or HSR-PRP Switch IP Substation Bay 1 Substation Bay 2 Substation Bay N How PRP Provides Network Redundancy PRP redundancy is implemented in the nodes rather than in the network. Especially adapted nodes (Dual Attached Nodes DANs), are connected to two independent Ethernet networks (LAN A and LAN B), and send the same frames over both networks. In a fault free state, destination nodes consume the first received frame and discard the duplicates. In case of a fault in one of the networks, the frames will still be transmitted and received through the other. PRP is suitable to be used for Station and Inter Bay Bus, and combined with HSR can offer full redundancy to the Substation Automation Network.

6 Reliable Ethernet Solutions SoCe offers high performance, IEC Clauses 4 and 5 Reliable Ethernet Solutions, implementable on Xilinx FPGAs. In all cases: Our proprietary implementation of the duplicate/circulate discard tables allows us to offer reduced latency times, by accepting or discarding frames in close to 3 µs The modularity of our solutions available in our portfolio allows implementations of HSR nodes, PRP nodes or different combinations of HSR, PRP and IEEE 1588 V2 Reference Design implements Redbox Functionality, and allows you to attach any single Ethernet port device to the redundant network HASARnet and PRPnet SoPCs Both are based on on chip soft Microblaze Processor and Linux Operation System. PRPnet is a single FPGA based solution for the implementation of the PRP 1 (IEC Clause 4) networks HASARnet, also single FPGA based, implements the HSR 1 (IEC Clause 5) protocol HASARnet and PRPnet support IEEE 1588 V2 via PreciseTimeBasic

7 HSR/PRP Switch IP Core Our latest and most powerful and versatile solution, HSR/PRP Switch is a HDL IP Core for the implementation of both the HSR 1 (IEC Clause 5) and PRP 1 (IEC Clause 4) protocols in a single device. HSR/PRP Switch IP Core: It switches frames by hardware. This feature offers high switching speeds, needed to fulfill the Maximum Allowed Age and Data Integrity set for Process Bus and Interbay Bus It is an all hardware IP.

9 IEEE V2 Synchronization Solutions Time synchronization is especially important for time stamping of Sampled Values (IEC ) of voltage and current. These values require accurate clocks inside the merging units. SoCe offers a wide range of solutions you can use to implement the Precise Time Protocol (PTPv2) IEEE V2 in order to fulfill Time Synchronization requirements for Station, Inter Bay and Process Bus. PreciseTimeBasic SoPC PreciseTimeBasic is an IEEE v2 compliant clock synchronization IP Core for FPGA devices. It timestamps and processes PTPv2 frames by hardware inside the FPGA and before the Ethernet MAC IPs It is able to work as a master or slave clock, as well as an ordinary or boundary clock It allows the implementation of PTP high level functions via an Open Source or IXXAT stack offering a different ranges of accuracy (starting at 300 ns) It includes an embedded soft processor offering all management functionalities (System on Programmable Chip) Sampled Value (SV) process buses allow for the removal of potentially lethal voltages and damaging currents inside substation control rooms and marshalling kiosks, reduce the amount of cabling required in substations, and facilitate the adoption of non conventional instrument transformers. IEC provides an inter operable solution to support multi vendor process bus solutions. IEEE Std , Precision Time Protocol version 2 (PTPv2), provides the greatest accuracy of network based time transfer systems D. M. E. Ingram, D. A. Campbell, and P.
