Avnu Alliance and TSN Developments at Hannover Messe

Avnu Alliance and TSN Developments at Hannover Messe

Hannover Messe continues to reflect the trend of companies joining alliances to develop and promote standards and interoperability. While I did not have an interview with the Avnu Alliance while I was in Hannover, I talked with some members and obtained other information. Avnu Alliance promotes adoption of the Time Sensitive Networking (TSN) extension to Ethernet.

Specifically, Avnu Alliance is a community creating an interoperable ecosystem of low-latency, time-synchronized, highly reliable networked devices using open standards. Avnu creates comprehensive certification programs to ensure interoperability of networked devices. The foundational technology enables deterministic synchronized networking based on IEEE Audio Video Bridging (AVB) / Time Sensitive Networking (TSN) base standards. The Alliance, in conjunction with other complimentary standards bodies and alliances, provides a united network foundation for use in professional AV, automotive, industrial control and consumer segments.

The adoption pace of TSN from 2017 to 2018 was amazing.

I always drop by the Industrial Internet Consortium (IIC) area at Hannover and check out the TSN Testbed for Flexible Manufacturing. The testbed was developed with two major goals – to show TSN’s readiness to accelerate the marketplace; and to show the business value of TSN in converged, deterministic IIoT networks. Momentum is increasing for the testbed, with the IIC hosting its 10th plugfest in an 18-month timeframe at the Bosch Rexroth facility in Frankfurt, Germany and its 9th plugfest, which was held in Austin, TX in February at National Instruments (NI) headquarters following a joint workshop on interoperability with Avnu Alliance. The TSN Testbed recently integrated test tools from Avnu Alliance members, Calnex, Ixia and Spirent into plugfest activities, and demonstrated interoperability of TSN devices from more than 25 companies performing real-time automation and control automation functions over TSN.

Any Avnu Alliance member is welcome to join the IIC TSN Testbed or to participate in a plugfest. Upcoming plugfests will be held in Austin, TX from June 26-29, 2018 and in Stuttgart from July 24-27, 2018.

The Edge Computing Consortium (ECC) along with members and Avnu Alliance, hosted a press conference to announce new developments surrounding the newly created OPC UA TSN testbed. The testbed demonstrates six major IIoT scenarios mimicking processes found in smart manufacturing settings and utilizing products across different TSN vendors. Avnu Alliance is a key partner supporting the development of the testbed with the ECC in the shared goal of enabling manufacturers to test their products for interoperability and conduct trials of real-world systems as an early check for problems.

Tom Weingartner, Avnu Alliance member and Analog Devices’ marketing director for Deterministic Ethernet Technology Group, represented the Alliance at an announcement ceremony.

Paul Didier, Avnu Alliance member and IoT solutions architect, Cisco delivered a talk at the Industrie 4.0 meet the Industrial Internet Forum, in a presentation titled “Time Sensitive Networks – Where does the technology stand and what to expect”. He will provide an update on TSN and how manufacturers, alliances and liaison groups are working together to advance the technology and its implementation in the IIoT.

Paul will present an additional lecture for the Forum on “Modernizing Your Industrial Manufacturing Network”. The presentation will follow the findings coming out of the IIC TSN Testbed and its capabilities, including information on how manufacturing automation and control infrastructure vendors and key decision-makers can leverage TSN for a variety of operational benefits, including increased connectivity between devices and the ability to extract and analyze valuable information through interconnectivity.

“HANNOVER continues to be a key industry event for both Avnu Alliance members and liaison groups that we work with to educate and increase awareness of TSN as a solution for the growing IIoT,” said Todd Walter, Avnu Alliance Industrial Segment Leader and Chief Marketing Manager at NI. “Whether through the developments coming from the TSN testbeds, speaking engagements or product demonstrations, our members and partners are committed to creating an interoperable TSN network that gives all industrial devices a more streamlined path to participating in the TSN ecosystem.

Avnu Alliance Plus Partnerships Plus TSN Yields Internet of Things Advances

Avnu Alliance Plus Partnerships Plus TSN Yields Internet of Things Advances

2017 marks the year of Avnu Alliance, the consortium driving standards-based deterministic networking, making its name in the industrial Internet of Things space. I’ve caught up with news from other trips, now it’s news from SPS in Nuremberg that I missed this year.

  • Avnu Alliance and Edge Computing Consortium
  • Avnu Alliance and OPC Foundation
  • TSN Conformance Testing

Avnu Alliance and the Edge Computing Consortium

Avnu Alliance and the Edge Computing Consortium (ECC) announced a liaison agreement to partner on shared interests of advancing industrial networking and edge computing. Under the agreement, the consortia will work together with the shared goal for interoperability across the industrial control industry.

Joint activities between Avnu Alliance and the ECC will include:

  • Identifying and sharing IIoT best practices
  • Collaborating on test beds
  • Collaborating on standardization and conformance testing

“We are very excited about the cooperation between ECC and Avnu Alliance,” said Mr. Haibin Yu, Chairman of ECC. “We believe that Time Sensitive Networking (TSN) technology will enable edge computing to better meet the industrial customers end-to-end needs and promote the global industry digitization transformation.”

“Edge computing is a key enabling technology to the industrial IoT. The liaison with the Edge Computing Consortium enables Avnu to broaden the scope for creating an interoperable foundation of Time Sensitive Networking (TSN) for the industrial IoT in alignment with our organization’s goal to build coalitions within the networking space,” said Todd Walter, Avnu Alliance Industrial Segment Chair.

Avnu Alliance and ECC conducted a joint presentation at the ECC Summit in Beijing on November 29, 2017 to announce their agreement and the opportunities ahead for Edge Computing and Time Sensitive Networking.

Avnu Alliance and OPC Foundation Combined IT-OT Leadership

Avnu Alliance (Avnu), Industrial Internet Consortium (IIC), and OPC Foundation announce their collaboration with IT-OT industry leaders to advance industrial device interoperability and to show the progress made in bringing the open, unified communication standard OPC UA over Time Sensitive Networking (TSN) to market.

Leading companies active in these groups have pledged their commitment to ensuring the interoperability of deterministic industrial devices and have made significant investments in achieving this goal. Rapid developments of these technologies have been made over the last year.

“With the rapid adoption of TSN as a foundational technology for automation, the community is increasingly relying on an interoperable set of network services and infrastructure. Today, 17 market leaders are reinforcing their commitment to complete a unified communication technology,” said Todd Walter, Avnu Alliance Industrial Segment Chair. “By leveraging the liaison agreements of Avnu, IIC and OPC Foundation, we’re creating a faster process for the creation of an open, interoperable ecosystem of devices that take advantage of secure, guaranteed latency and delivery for critical traffic. It is exciting to see the fruits of our labor in these milestones.”

The pillars of this announcement are:

Conformance testing advances: Avnu TSN conformance test plans for time synchronization of industrial devices are ready and available to test houses. At last month’s Avnu IIC Interoperability Workshop, more than 20 companies came together to demonstrate interoperability in the IIC TSN Testbed and to advance the conformance tests with the assistance of University of New Hampshire InterOperability Lab, an Avnu-recognized test facility.

Standards evolved, more vendors, more devices: The Publish Subscribe extension for OPC UA is now available in release-candidate form, enabling the exchange of OPC UA over UDP connections. This is the prerequisite for running OPC UA TSN.

“OPC UA over TSN adds additional capability to the OPC Foundation portfolio, including enhancing controller-to-controller and machine-to-machine communication and information integration. OPC UA addresses the complex requirements of initiatives like Industrie 4.0 and the IIoT, providing information integration between devices, applications and the cloud, truly providing the foundation for the much-demanded seamless communication and information integration between IT and OT networks,” said Thomas Burke, OPC Foundation President.

Demonstrated interoperability between different vendors: Interoperability testing via the IIC TSN Testbed is rapidly progressing with eight hands-on plugfests taking place in the US and Europe over the past 18 months. More than 20 companies have participated in these face-to-face events to test and demonstrate interoperability between devices from various manufacturers and vendors – both collaborative and competitive.

“Our TSN Testbed stands as a showcase for the business value of TSN. The work coming out of the TSN Testbed is already having a direct impact on suppliers and manufacturers who see the technology as a value-add for their system structures,” said Paul Didier, IIC TSN Testbed Coordinator, Cisco Solution Architect. “Companies are invited to participate in our plugfests to test their own TSN devices for interoperability, including OPC UA Pub-Sub TSN devices.”

Avnu Alliance Delivers First TSN Conformance Tests for Industrial Devices

Avnu Alliance announced the first set of Avnu TSN conformance test plans for time synchronization of industrial devices are ready and available now for test houses to implement.

Avnu Alliance has built a rich set of conformance and interoperability tests with a defined procedure for certification in various markets. Leveraging that multi-industry experience, Avnu defined a baseline certification in the industrial market that consists of robust and comprehensive test requirements based on the market requirements for industrial automation devices and silicon. These conformance tests ensure that the device or silicon conforms to the relevant IEEE standards, as well as additional requirements that Avnu has selected as necessary for proper system interoperability.

“Time Synchronization, or 802.1AS, is the foundation for all TSN devices, hence it is the first set of conformance tests that are ready and available,” said Todd Walter, Avnu Alliance Industrial Segment Chair. As the standards and networks continue to evolve, so does Avnu’s work to define and certify the standard foundation. In the future, Avnu will also be able to test and certify other traffic shaping mechanisms, frame preemption, redundancy, ingress policing, strict priority, and security. “Our work with the Industrial Internet Consortium (IIC), OPC Foundation and other industry organizations drives the industry closer toward achieving an interoperable ecosystem,” added Walter.

Avnu is committed to speeding up the path to an interoperable foundation. To this end, Avnu members have made open source code available for 802.1AS timing and synchronization in the OpenAvnu repository on GitHub.

To encourage and enable multiple industry groups, vendors and protocols to share a TSN network, Avnu has outlined the system architecture and requirements for this industrial model built on an Avnu certified foundation in a document entitled “Theory of Operation for TSN-enabled Industrial Systems,” which is available for download. This document introduces the fundamental mechanisms needed for a system architecture to build on, including time synchronization, quality of service using scheduled transmission and network configuration and walks through the requirements of several industrial use cases including how to enable and integrate non-TSN technologies where needed.

Avnu Alliance members have created this document to help designers and engineers in the industry understand the real-world application context and build a TSN network that is configured for multiple vendor and industry groups. Avnu’s defined foundation will continue to support additional capabilities, including support for multiple IEEE 1588 profiles, guidelines for scaling to very large network architectures, centralized and distributed configuration for the network, and aggregation/composition of multiple networks into a single TSN-enabled network domain.

“Both Avnu and the IIC are well aligned to pursue the advancement of the IIoT. An example of this is Avnu’s participation in the IIC TSN testbed where members have an opportunity to try their equipment and software on the testbed infrastructure. This provides the participants with the ability to discover what’s working and what is not and provide feedback that helps speed market adoption,” said Gary Stuebing, IIC liaison to Avnu. “The lessons learned in our TSN testbed fuel the ability of both of our organizations. TSN could open up critical control applications such as robot control, drive control and vision systems.”

“Our liaison agreement and work with the IIC TSN Testbed demonstrates real-world applications and solutions with TSN and helps to accelerate readiness for the market. The testbed stands as a showcase for the value that TSN standards and ecosystem of manufacturing applications and products bring to the market, including the ability for IIoT to incorporate high-performance and latency-sensitive applications,” said Todd Walter, Avnu Alliance Industrial Segment Chair. “Our collaboration with IIC and the work coming out of the TSN Testbed is already having a direct impact on suppliers and manufacturers who see the technology as a value add for their system structure.”

Avnu and IIC are meeting for a TSN Testbed plugfest later this month to evaluate and trial TSN device conformance tests that are being developed as a baseline certification in the industrial market.

Avnu creates comprehensive certification tests and programs to ensure interoperability of networked devices. The foundational technology enables deterministic synchronized networking based on IEEE Audio Video Bridging (AVB) / Time Sensitive Networking (TSN) base standards. The Alliance, in conjunction with other complementary standards bodies and alliances, provides a united network foundation for use in professional AV, automotive, industrial control and consumer segments.

Smart Factory Machine Learning for Predictive Maintenance Testbed

The Industrial Internet Consortium announced the Smart Factory Machine Learning for Predictive Maintenance Testbed. The testbed is led by two companies, Plethora IIoT, a company, designing and developing cutting-edge answers for Industry 4.0, and Xilinx, the leading provider of All Programmable technology.

This innovative testbed explores machine-learning techniques and evaluates algorithmic approaches for time-critical predictive maintenance.  This knowledge leads to actionable insight enabling companies to move away from traditional preventative maintenance to predictive maintenance, which minimizes unplanned downtime and optimizes system operation.  This would ultimately help manufacturers increase availability, improve energy efficiency and extend the lifespan of high-volume CNC manufacturing production systems.

“Testbeds are the major focus and activity of the IIC and its members. We provide the opportunity for both small and large companies to collaborate and help solve problems that will drive the adoption of IoT applications in many industries”, said IIC Executive Director Dr. Richard Mark Soley. “The smart factory of the future will require advanced analytics, like those this testbed aims to provide, to identify system degradation before system failure. This type of machine learning and predictive maintenance could extend beyond the manufacturing floor to have a broader impact to other industrial applications.”

“Downtime costs some manufacturers as much as $22k per minute. Therefore, unexpected failures are one of the main players in maintenance costs because of their negative impact due to reactive and unplanned maintenance action. Being able to predict system degradation before failure has a strong positive impact on machine availability: increasing productivity and decreasing downtime, breakdowns and maintenance costs,” said Plethora IIoT Team Leader Javier Diaz.  “We’re excited to lead this testbed with Xilinx and work alongside some of the leading players in IIoT technologies. This is a unique opportunity to test together machine learning technologies with those involved in the testbed at different development levels starting from the lab through production environments, where a real deployment solution is utilized. As a result, from these experiences, we can significantly reduce the time-to-market of Plethora IIoT solutions oriented to maximize smart factory competitiveness.”

”Xilinx is committed to providing the Industrial IoT industry with our latest All Programmable SoC and MPSoC platforms – ideal for sensor fusion, real-time, high-performance processing, and machine learning from the edge to the cloud,” stated Dan Isaacs, Director of Corporate Strategic Marketing and Market Development for IIoT and Machine Learning at Xilinx. “The combination of these highly configurable capabilities drives the intelligence of the smart factory.”

Additional IIC member companies participating in this testbed are: Bosch, Microsoft, National Instruments, RTI, System View, GlobalSign, Aicas, Thingswise, Titanium Industrial Security, and iVeia. They provide technologies to enable the Smart Factory Machine Learning testbed, including:

  • Factory automation
  • OT and IT security
  • Edge to cloud machine learning and analytics
  • Time-sensitive networking (TSN)
  • Data acquisition
  • Smart sensor technology

Control and Networking Make Automation News

Control and Networking Make Automation News

Here is some news regarding control and networking. Bedrock Automation is a recent entrant into the control and automation space, while Time Sensitive Networking (TSN) holds great potential to be a disruptive force.

Control

I seldom write about automation company “wins”, but this one shows some direction for a new company. Bedrock Automation is a young automation company that has built a new control platform from the ground up for not only the latest in control but also for security.

My curiosity has focused on where it would find a market. I don’t see it displacing Rockwell Automation and Siemens any time soon, but the platform is robust and adaptable. This looks like a perfect application.

Pinnacle Midstream, a Houston-based supplier of storage and processing services for the oil and gas industry, has selected the Bedrock control system as the automation platform for its crude oil receipt and delivery points. The Bedrock system will coordinate flow of product from partners, through the Pinnacle processing facilities and onto refiners and shippers. Pinnacle chose Bedrock system for its scalability, ease of engineering, ruggedness, cost efficiencies and intrinsic cyber security.

“We are expanding to the meet the growing need for midstream services and need a secure way to centralize control of flow amongst our facilities. The Bedrock system provides an economical solution in a small, easy-to-implement system that can coordinate edge control today, while also scaling easily and economically to the full DCS functionality we expect to need in the future. We also liked the rugged Bedrock housing, which will resist the dust that gets into everything around here,” said Mike Hillerman, VP of Engineering and Operations for Pinnacle Midstream.

Networking

Avnu Alliance, the industry consortium driving open standards-based deterministic networking through certification, is co-hosting the 2017 Time Sensitive Networks and Applications (TSN/A) Conference with WEKA FACHMEDIEN on September 20-21 at the Mövenpick Hotel Stuttgart Airport in Germany.

The TSN/A Conference is a combination of the “TSNA Conference” and the “Industrial Ethernet TSN Kongress” and offers attendees insights into Time-Sensitive Networks and usage in applications for Automotive, Industrial, Professional Audio/Video and more. The conference spans two days of technical sessions, panel discussions, vendor demonstrations, and participant networking.

“We are excited to bring together experts and thought leaders from around the world to the TSN/A Conference in Germany this year” said Kevin Stanton, Avnu Alliance Chairman, who will also deliver a conference presentation on Time Synchronization on Wired and Wireless Infrastructure. “It’s been a pleasure to join forces with WEKA FACHMEDIEN as the speakers present both the technology of TSN and its implications across our industries.”

On Wednesday, September 20, the first day of the conference, programming will feature two keynotes from Avnu Alliance members. Wolfgang Schenk of Hirschmann Automation and Control will present on “Time-Sensitive Networking: Enabling Technology for the Automation Model of the Future,” analyzing the transformation of the automation pyramid towards an automation pillar and discussing why TSN is the enabling technology for this transformation. Avnu Alliance Member BMW representative Dr. Kirsten Matheus will give a keynote on the “Use of AVB and TSN in the Automotive Industry.” Specifically, the presentation will describe the results of two workshops that Avnu Alliance held to gauge the need in the automotive industry for different Audio Video Bridging (AVB)/TSN functions.

I am happy to see momentum building for the technology. Can’t wait to see applications.

Avnu Alliance Members Endorse TSN Market Value at Hannover Messe and Deterministic Ethernet Forum

Avnu Alliance Members Endorse TSN Market Value at Hannover Messe and Deterministic Ethernet Forum

The Time Sensitive Network (TSN) standard is in development by the 802 committee of the IEEE. This is the Ethernet committee as TSN is a set of standards (some have been adopted) extending Ethernet into the realm of determinism. One driving force behind development and implementation of the standard is the Avnu Alliance.

First, a quick look at the standard. Three relevant standards exist. IEEE 802.1AS (IEEE 1588)—Timing & Synchronization; IEEE 802.1Qbv—Forwarding and Queuing; IEEE 802.1Qcc—System Configuration. These deal with a synchronized clock, deterministic packet delivery, and system setup.

Now the news. Members of the Avnu Alliance, the industry consortium driving open, standards-based deterministic networking, actively endorsed Time Sensitive Networking (TSN) and advanced the TSN device roadmap at Hannover Messe from April 23 – 27, 2017 and Deterministic Ethernet Forum (DEF) from April 27 – 28, 2017. Members across the industrial and automotive markets participated in presentations and trainings, as well as product and testbed demonstrations at the events.

“The business value of TSN for industrial and automotive applications was a theme in the presentations and panel discussions at DEF this year. It is more clear than ever that Avnu Alliance is the place where leading manufacturers are working together to ensure we have a common, interoperable infrastructure for TSN and a future-proof network,” said Kevin Stanton, Avnu Board of Directors Chairman.

A key demonstration at both events was the Industrial Internet Consortium (IIC) sponsored TSN Testbed that Avnu Alliance and many of its members participate in.  As the world’s first testbed for TSN, it was developed with two major goals – to show TSN’s readiness to accelerate the marketplace; and to show the business value of TSN in converged, deterministic IIoT networks. At Hannover Messe, the TSN Testbed was on display in both the IIC booth and the OPC Foundation booth for attendees to see demonstrations of a real-world TSN network with numerous Avnu member products and prototypes from companies including Analog Devices, Belden, Bosch, Cisco, Hilscher, National Instruments, Renesas, Schneider Electric, and TTTech.

The testbed highlighted the ability for the IIoT to incorporate high-performance and latency-sensitive applications. The work coming out of the TSN Testbed is already having a direct impact on suppliers and manufacturers who see the technology as a value add for their system structure.

Avnu members Cisco and Belden both made TSN announcements at Hannover Messe. Cisco announced that it has added TSN support to the IE4000 Switch family of products. Belden in turn presented the company’s TSN upgrade path for select products from its industrial switch portfolio, starting with the RSPE35 and RSPE37 switch family. Analog Devices also showed TSN at the PROFINET International and ODVA stands at Hannover Messe. These demonstrations showed TSN compatibility with existing Industrial Ethernet protocols as well as convergence of TSN with standard Ethernet traffic. Later the same week at the DEF hosted by TTTech, Avnu Alliance leadership delivered the welcome address and members led discussions around topics such as, “How the IIC Testbed Drives Vendor Interoperability” and “Deterministic Ethernet Will Help to Meet the Need for Speed for Future Automotive Applications.”

Standards are just nice ideas unless there is a conformance test and a test and certification agency. For example, such a system assures WiFi device compliance to that standard.

In 2017, Avnu Alliance will continue work towards Avnu certification of TSN devices and offer collective multi-industry experience and networking expertise to manufacturers looking to expedite advanced networking implementations, ultimately leading to a faster path to market for industrial manufacturers. “With IIoT, there is a strong reliance on open standards to enable secure, predictable, reliable, and uninterrupted flow of information from sensor to cloud. Avnu members influence and shape the evolving standards; thus enabling them to deliver the value of TSN for customers and instil confidence in the stability of the technology. With the rapid adoption of TSN as a foundational technology for automation, the community is increasingly counting on an interoperable set of network services and infrastructure.  The conformance testing and certification provided through Avnu will be critical to provide the needed interoperable network for the IIoT,” said Todd Walter, Avnu Alliance Industrial Segment Chair.

Industry Support for TSN and Avnu Alliance:

“Open standards are key to enabling the data-centric applications of Industrie 4.0 and the IIoT.” said Dr. René Hummen, senior architect technology and innovation at Belden. “IEEE TSN is an important piece in this puzzle by providing for deterministic and reliable data transmissions, converged data networks, and continuous data access without gateways. Avnu certification of TSN will ensure interoperability of the various end-systems and network infrastructure devices that IIoT applications rely on.”

“Great interest in TSN became apparent at Hannover Fair in the IIC Consortium, OPC Foundation and TTTech booths. There was encouraging feedback we received around the broad possibilities TSN offers for the different industries. These possibilities were also on the agenda at the successful Deterministic Ethernet Forum in Vienna, with 250 participants from 23 countries, representing industrial and automotive companies, consortia as well as semiconductor companies,” said Markus Plankensteiner, VP sales industrial North America and global alliance manager at TTTech Computertechnik AG. “The tremendous progress of TSN in the last months was conveyed with presentations from industry experts. Also, concrete products utilizing the technology were announced, among them a variant of the Intel Cyclone V SoC, featuring TSN switching functionality by TTTech. It is crucial to use the momentum of the technology to start building great products that will increase the acceptance of TSN even further.”

“Hannover Messe is an enormous trade show and this year TSN seemed to be everywhere – much more than in previous years, “said Tom Weingartner, Marketing Director, Deterministic Ethernet and IIoT Communication Technology for Analog Devices. “We received positive feedback from the demonstrations of TSN we gave at the show. Interoperable networking protocols like TSN make convergence on the network seamless and help ensure that as the IIoT expands, there is a strong infrastructure supporting it.”

The Avnu Alliance is a community creating an interoperable ecosystem of low-latency, time-synchronized, highly reliable networked devices using open standards. Avnu creates comprehensive certification programs to ensure interoperability of networked devices. The foundational technology enables deterministic synchronized networking based on IEEE Audio Video Bridging (AVB) / Time Sensitive Networking (TSN) base standards. The Alliance, in conjunction with other complimentary standards bodies and alliances, develops complete solutions in professional AV, automotive, industrial control and consumer segments.
