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.
Time Sensitive Networking, or TSN, extends and amplifies standard Ethernet as defined by the IEEE. The complete suite of specifications lacks a couple of areas, yet, but it is complete enough to begin using. NI (National Instruments) has been an early proponent of the technology participating in a testbed assembled by the Industrial Internet Consortium.
I’m a TSN believer. When the complete set of specs if finished and we see commercial-off-the-shelf chipsets, this high speed, deterministic network will be a game changer for the Internet of Things and indeed industrial control and automation. The amount of murmuring I’m hearing from suppliers confirms in my mind the potential.
NI has announced new CompactRIO Controllers that include NI-DAQmx and Time Sensitive Networking (TSN). These controllers offer deterministic communication and synchronized measurements across standard Ethernet networks to increase performance and help improve productivity in addition to flexibility. NI was the first to market with industrial embedded hardware supporting TSN, the next evolution of the IEEE 802.11 Ethernet standard, and provides these controllers as part of its continued investment in TSN. Engineers can use TSN to synchronize distributed systems across networks, which eliminates the need for costly synchronization cables.
As industries such as automotive, oil and gas, research and aerospace continue to implement the Industrial Internet of Things (IIoT), acquiring accurate, reliable and synchronized data across distributed nodes has become more challenging. As a result, companies must keep pace to ensure their systems are ready to meet these evolving requirements.
In the research space, A.M.S. Software GmbH is already taking advantage of the flexibility of CompactRIO with NI-DAQmx. “We are excited about the new CompactRIO Controller because of the flexibility it offers us,” said Klaudius Pinkawa, CEO of A.M.S. Software GmbH. “We needed to set up several experiments in a lab and then perform them on an aircraft in zero gravity. CompactRIO with NI-DAQmx allowed us to perform any experiment using the same hardware in both environments, which saved development time and reduced risks to the experiments.
The new CompactRIO Controllers feature:
- Submicrosecond synchronization with TSN over standard Ethernet for tightly synchronized, distributed measurements and control
- Shorter time to measurement than previous CompactRIO Controllers because of intuitive NI-DAQmx driver software
- Open and secure processing at the edge of the IIoT with the NI Linux Real-Time OS
- High-performance data analysis and control with an industrial-grade processor and onboard FPGA, programmable with LabVIEW FPGA
- Reliable operation in harsh environments with -40 °C to 70 °C operating temperature range, shock resistance up to 50 g and vibration resistance up to 5 g
With the addition of NI-DAQmx to the CompactRIO Controller family, engineers can access I/O directly from ready-to-use functions, which have made working with this driver the preferred data acquisition method for over 15 years. This intuitive driver coupled with the openness of the NI Linux Real-Time OS means users can continue to leverage the vast ecosystem of IP available for Linux, like Security Enhanced Linux (SE-Linux).
Security comes first to mind whenever we begin discussing connecting things in an industrial setting. And, of course, nothing connects things like the Industrial Internet of Things (IIoT). One place we often fail to consider in our security planning is at the endpoint of the network. Organizations and companies have been providing valuable assistance to developers by releasing best practices white papers. Here is one from a leading Industrial Internet organization.
The Industrial Internet Consortium (IIC) announced publication of the Endpoint Security Best Practices white paper. It is a concise document that equipment manufacturers, critical infrastructure operators, integrators and others can reference to implement the countermeasures and controls they need to ensure the safety, security and reliability of IoT endpoint devices. Endpoints include edge devices such as sensors, actuators, pumps, flow meters, controllers and drives in industrial systems, embedded medical devices, electronic control units vehicle controls systems, as well as communications infrastructure and gateways.
“The number of attacks on industrial endpoints has grown rapidly in the last few years and has severe effects. Unreliable equipment can cause safety problems, customer dissatisfaction, liability and reduced profits,” said Steve Hanna, IIC white paper co-author, and Senior Principal, Infineon Technologies. “The Endpoint Security Best Practices white paper moves beyond general guidelines, providing specific recommendations by security level. Thus, equipment manufacturers, owners, operators and integrators are educated on how to apply existing best practices to achieve the needed security levels for their endpoints.”
The paper explores one of the six functional building blocks from the IIC Industrial Internet Security Framework (IISF): Endpoint Protection. The 13-page white paper distills key information about endpoint device security from industrial guidance and compliance frameworks, such as IEC 62443, NIST SP 800-53, and the IIC IISF.
Equipment manufacturers, industrial operators and integrators can use the Endpoint Security Best Practices document to understand how countermeasures or controls can be applied to achieve a particular security level (basic, enhanced, or critical) when building or upgrading industrial IoT endpoint systems, which they can determine through risk modeling and threat analysis.
“By describing best practices for implementing industrial security that are appropriate for agreed-upon security levels, we’re empowering industrial ecosystem participants to define and request the security they need,” said Dean Weber, IIC white paper co-author, and CTO, Mocana. “Integrators can build systems that meet customer security needs and equipment manufacturers can build products that provide necessary security features efficiently.”
While the white paper is primarily targeted at improving the security of new endpoints, the concepts can be used with legacy endpoints by employing gateways, network security, and security monitoring.
The full Endpoint Security Best Practices white paper and a list of IIC members who contributed can be found on the IIC website.
The Industrial Internet Consortium (IIC) has been busy over the past few months. I receive a steady stream of interesting news. This one concerns a joint Forum (which I cannot make) with National Institute of Standards and Technology (NIST) presenting the IIoT Energy Forum on February 9 in McLean, Virginia.
This one-day forum hosted by the MITRE Corp. will focus on the impact of IIoT on the energy industry.
This public event will showcase industrial internet technologies and IIC and NIST activities in the energy sector. It will feature experts from both the IIC and NIST and shine a spotlight on smart grids, industrial analytics, cybersecurity and standards.
“The Global Event Series is a crucial part of IIC’s industry outreach program bringing industry stakeholders and end users together,” said Wael William Diab, Chair of the IIC Global Event Series and Senior Director at Huawei. “Many industries are turning to IIoT to monitor the efficiency of their assets and the energy and utility sector is no exception.”
“IIoT-enabled assets present new vectors of vulnerability across connected systems and distributed devices in the energy and utility industry,” said Bob Martin, Senior Principal Engineer, Trust & Assurance Cyber Technologies, The MITRE Corporation. “Trustworthy IIoT will have an impact not only on cost optimization but also on energy regulations, policy and standards.”
The agenda includes:
- Guest speakers from The Department of Energy, MITRE and NIST who will discuss requirements, gaps and opportunities for leveraging the data that is building up within and around energy systems, and how to use that data to increase production and decrease costs.
- A panel of testbed experts from Xilinx, Wipro Digital, NIST and InterDigital Communications, Inc. who will discuss emerging technologies and applications based on testbed examples, including smart grids.
- Panels on Standards & Architecture and Security, moderated by IBM and Intel respectively, both with a focus on energy.
MITRE is a secure facility and pre-registration is required. Registration for non-US citizens closes on January 24 at 5pm EST and registration for US citizens closes January 31 at 5pm EST.
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 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.
