[Huawei Alliance Alliance Partner Releases TSN+OPCUA Testbed for Six Industrial Interconnections] Recently, the Industrial Internet Industry Alliance (AII), the Avnu Alliance, the Edge Computing Industry Alliance (ECC), FraunhoferFOKUS, Huawei, and National Instruments (NI) Over 20 international organizations and well-known companies in the industry, such as Schneider Electric, B&R, and other well-known industrial companies, have jointly announced the inclusion of predictability at the world's largest industrial exhibition, the Hannover Messe 2018 in Germany. Maintain TSN (Time Sensitive Networking) + OPCUA (OPC Unified Architecture) test bed in six scenarios of industrial interconnects such as network, motion control synchronization scenarios, and motion control for drawing. As we all know, the combination of TSN and OPCUA is a key driving factor for new technologies such as predictive maintenance, data analysis, machine learning, and artificial intelligence. It is also helping industrial enterprises to reach the “last mile†of the industrial Internet and improve the overall efficiency of equipment and reduce costs. Important support.
The joint launch of the TSN+OPCUA test bed, which includes six scenes of industrial interconnection, is not only a key step towards the ultimate realization of industrial field information interaction, but also will further promote digital transformation of the industry. Thanks to its many years of accumulation in the TSN field, NI and Huawei have created a distributed motion control synchronization system in this release of the TSN+OPCUA test bed, simulating a rich real-world smart manufacturing scenario and collaborating with other five major industrial interconnect scenarios. Demo jointly verifies the high certainty and low delay of the TSN network. It is also a concentrated expression of the vision of the 20+ global leading international organizations and vendors including NI and Huawei in making concerted efforts to open the “last mile†vision of the industrial Internet. In the industry, the German Hannover Fair is known as the “industrial development vane of the global industry.†Rahman Jamal, Marketing & Technology Director of the NI Technology (Business & Technology Fellow), was invited to participate in the joint release of the TSN+OPCUA test bed held by Huawei at the Hanover Industry Fair in Germany in 2018. During the ceremony, "NI joined the first TSN + OPCUA testbed led by the Industrial Internet Industry Alliance (IIC) in 2016. Today our partner Huawei demonstrated this case to emphasize TSN's importance to the Industrial Internet of Things again. Sex, NI’s continued investment and leadership in the TSN field also proves this.†Rahman added: “NI is a member of the standards development team as part of the IEEE organization and has always played an active role; we are also members of the Avnu Alliance Board of Directors; In addition, NI is chairman of the OPC Foundation's TSN Working Group; finally, we are an active member of the IIC, leading the push for multiple test bed projects, and more importantly, NI has launched support for TSN and OPC UA. Products, we are proud to be able to land TSN+OPCUA technology as synchronous, deterministic communication The leading solution in the field.

Joint Huawei released a motion control synchronization system, NITSN technology can not be less!
As mentioned earlier, in this TSN+OPCUA test bed with six major industrial interconnect scenarios, NI's contribution focuses on the demonstration scenario for motion control synchronization scenarios. Based on two NI CompactRIO embedded controllers that support TSN, NI provides a demonstration solution for a distributed motion control system that combines multiple high-reliability and ultra-low latency TSN rings with multiple control nodes The application scenario of high-precision synchronization and real-time communication also reaffirmed the high degree of certainty and low latency of the strict synchronization of TSN networks in complex environments.
Figure 2. Rahman Jamal (right), director of marketing strategy and technology at NI, explains how NITSN technology can be applied to the entire TSN+OPC UA test bed
According to Yi Yulu, an NI technology market engineer, in the demonstration program of this distributed motion control synchronization system, two NI CompactRIO combinations constitute the Server-Client interconnect system, which is connected to a stepper motor and exercised. Based on the TSN technology, two control nodes can achieve <1us synchronization accuracy. In the test process, when NI attempts to send a series of interference data (such as video streaming data) in the TSN ring network, the system can still maintain the accuracy and synchronization of control operations. "This means that based on the traffic scheduling function of the TSN network, the system can effectively coordinate the priority of OT and IT data transmission, and ensure the determinism and real-time nature of the control signal transmission." Yi Xiaolu added.

Cracking the Industrial Internet's Not Real-time & Inconsistent, NI Thinks TSN+OPCUA Has Experience
Focusing on the current status of the development of industrial IoT, from the perspective of interconnection, on the one hand, existing networks are difficult to meet the needs of industrial production with high security, high real-time, and high reliability; on the other hand, due to the lack of a unified standard interface, universal accessibility is generally poor. Because of such difficulties, the network system supported by information and communication technologies has become the key to the advanced development of industrial IoT. As a group of protocol suites at the data link layer, the TSN that changes the uncertainty of the Ethernet from the underlying architecture is like a "descendant": high bandwidth up to 1 Gbit/s; seamless integration of existing applications and standards The interoperability of IT networks, the deterministic transmission time of the μs level, and the low latency/high synchronization of ns-level inter-node time synchronization, high security, and many other advantages all make TSN a methodology for assisting IIoT to accelerate the evolution of real-time.
Figure 4. NI believes that the continuous deepening of industrial interconnects makes high-bandwidth, real-time industrial on-site information interaction critical
Although TSN is still in the technical stereotype testing stage, TSN has indeed grown rapidly in recent years. In particular, the Avnu Alliance, Industrial Internet Alliance (IIC) and the OPC Foundation announced the introduction of OPC UA in TSN in 2017 and will lead the industry with IT-OT. The news of cooperation in promoting the interoperability of industrial IoT and Industry 4.0 has brought a lot of shock to the industry.
If the TSN focused on product interoperability and stability solves the problem of obtaining the underlying data, it provides a high degree of certainty and low latency in network communication; OPC UA solves the problem of application layer semantic parsing, and it provides a The platform-independent service-oriented architecture provides the necessary infrastructure for the interoperability of the entire enterprise and truly enables interaction between different vendors and different devices. The establishment of a unified channel based on the two will not only completely unify the data link service standards, but also more likely break the structure of traditional industries. Therefore, the industry generally believes that the integration of TSN and OPCUA will bring a whole new situation to the entire industry interconnection. At present, there are many mainstream industrial automation companies that are at the forefront of technology to start researching and implementing TSN+OPCUA. NI is one of them.
Optimistic about TSN as “a new outlet for industrial interconnectionâ€, the NITSN product matrix continues to expand
Back in November 2012, the IEEE 802.1 Task Force formally renamed AVB (Ethernet Audio Video Bridging Technology) to TSN, and also established 4 major application scenarios of TSN: Pro AV, automotive control, commercial Electronic field and the most extensive application in the future: All industrial fields that require real-time monitoring or real-time feedback. For a company that has taken root in the field of test and measurement, NI is an "all-inclusive" company with a global customer base and business scope. Therefore, the focus of NI's incubation product matrix is ​​to stick to its "software-centric" strategic core. And deepen the original intention of multi-industry testing requirements; on the other hand, it focuses on the emergence of “new wind†in the industry, how to form independent components that integrate new standards and new technologies and become more flexible based on existing products to cater to the needs of the market and users. Surge.
Therefore, in 2012, as a member of the International Industrial Internet of Things IIC, NI established the TSN task force to define, standardize, and promote the application of TSN with many industry leaders such as Cisco and Intel. With the increasing maturity of TSN technology and its further integration with OPCUA, it has added a fire to its hot TSN: the industry's first batch of TSN products, Intel, Broadcom, and MarvelTSN; and Cisco, Hirschmann and other companies have introduced switches that support TSN...and of course include the many distributed edge computing platforms supported by NI in the past two years that support TSN:
â— In 2016, NI introduced the first IP67-rated industrial IoT for IC-317x series industrial controllers for extreme environments. It is designed for automated image processing and control. Applications provide the highest level of processing capabilities and connectivity;
â— At NIWEEK 2016, National Instruments released the CompactRIOcRIO-9035 and cRIO-9039 embedded controllers that support TSN, providing the highest synchronization accuracy of <100ns based on the synchronization of multiple real-time processors and FPGAs based on the TSN network, which is particularly suitable for building. Distributed control system and coordinated OT+IT traffic scheduling;
◠On NIWEEK2017, NI once again introduced the new TSN-based CompactDAQ chassis - cDAQ-9185 and cDAQ-9189. As an Ethernet chassis dedicated to distributed measurement and synchronization, the CompactDAQ's highest synchronization accuracy is <100ns and multi-hop accuracy <1μs;
â— At the end of 2017, NI announced the introduction of a rugged, distributed, synchronized FieldDAQ device and introduced TSN into the most demanding test units and outdoor environments. Because FieldDAQ integrates TSN, it can support third-party TSN solutions for most industrial I/O and control vendors (such as Bosch, B&R, and Schneider Electric);

Of course, the new FieldDAQ is another product line besides industrial controllers, CompactDAQ, and CompactRIO. Its introduction will further predict the further expansion of NITSN products. In the future, NI will continue to vigorously promote the deployment of TSN technology and apply it to more industrial interconnect scenarios.
Eco-enveloping products, NI brings industry benchmark companies together to “stir†TSN air outlets
Internally, focusing on accumulating its own technological advantages; externally, actively exploring the boundaries of industrial cooperation. As a leader in the test and measurement industry, NI is not only a member of the Industrial Internet Consortium (IIC), a board member of the Avnu Alliance (Board of Directors), or China's edge computing. The executive member of the industry alliance (ECC) plays an important role in the global industrial interconnected ecosystem. In the TSN area, NI is also actively creating its own "TSN ecology."
As early as NIWEEK 2016, NI launched the world's first TSN experience technology platform jointly with Cisco and Intel. In early 2017, NI officially opened the Industrial IoTLab. One of the operational focuses is TSN flexible manufacturing. Hopefully, the alliance Cisco, Avnu Industry giants such as Alliance, Intel, and Xilinx demonstrated the cooperation of 12 companies on the TSN network through the demonstration of the TSN field test platform. At the end of 2017, NI added its annual new product, the TSN-based CompactDAQ chassis, to its world's first TSN experience technology platform. Compared with the traditional information transmission based on UDP, TSN is again verified that it can maintain the priority transmission of time-sensitive data, real-time and determinism, to ensure the seamless integration of IT and OT.
In fact, as early as the end of last year's 2017 Edge computing industry summit, NI, who is a member of the executive board of the Council of the Edge Computing Industry (ECC), has announced that it will cooperate with some of the core companies in the alliance and will be committed to leading foreign technologies. The advantages, such as TSN technology, combined with the uniqueness of the domestic vertical industry application scenes, accelerate the landing of edge computing in various industries, and Huawei is one of the founding members of ECC. I believe that in the near future, we will see more applications supported by NI and landing in Chinese industrial scenes.
