Recently, Industrial Internet Industry Alliance, Avnu Alliance, Edge Computing Industry Alliance (ECC), Fraunhofer FOKUS, Huawei, United States instrument (NI), Schneider Electric, B&R, etc. More than 20 international organizations and well-known manufacturers in the industry have formed a 'semi-industrial interconnection industry'. They were jointly released at the largest industrial exhibition in the world - 2018 Hannover Messe, Germany. Includes TSN (Time Sensitive Networking) and OPC UA (OPC Unified Architecture) testbeds for six scenarios including predictive maintenance networks, motion control synchronization scenarios, and motion control for mapping, etc. It is well-known that the combination of TSN and OPC UA. It is the key driver of predictive maintenance, data analysis, machine learning and artificial intelligence, and it is also an important support for helping industrial enterprises to reach the 'last kilometer' of the industrial Internet and improve the overall efficiency of equipment and reduce costs.
The joint launch of the TSN+OPC UA test bed including the six scenes of industrial interconnection will not only be a key step towards the ultimate realization of industrial site information interaction, but also will further promote the digital transformation of the industry. It will benefit from its own in the TSN field. After years of accumulation, NI and Huawei have created a distributed motion control synchronization system in the TSN+OPC UA test bed released this time. By simulating a rich real-world intelligent manufacturing scenario, the company jointly validated the TSN network in collaboration with other five major industrial interconnection scenarios. The high degree of certainty and low latency is also reflected in the collaboration of the 20+ leading global organizations and vendors including NI and Huawei to unify the vision of the 'last mile' of the Industrial Internet. In the industry, Hannover, Germany The Expo is known as the “industry of global industrial technology development”, and Rahman Jamal, Marketing & Technology Fellow of NI, was invited to participate in the joint launch of TSN+OPC UA Test Bed held by Huawei at the Hanover Industry Fair in Germany in 2018. Said that 'NI has joined the first TSN+OP led by the Industrial Internet Industry Alliance (IIC) in 2016 The C UA test bed, which was demonstrated today by our partner Huawei, once again emphasized the importance of TSN for industrial IoT. NI’s continued investment and leadership in the TSN field also proves this. “Rahman added: 'NI As a member of the standard development team part of the IEEE organization, we have always played an active role; we are also members of the Avnu Alliance Board of Directors; in addition, NI is the chairman of the OPC Foundation TSN Working Group; finally, we are an active member of the IIC, leading Several test bed projects were advanced. In addition, more importantly, NI has introduced products that support TSN and OPC UA. We are proud to be able to land TSN+OPC UA technology as the primary for synchronization and deterministic communication. Solution. Ensure that our customers can create interoperable test, measurement and control systems.

Jointly released Huawei's motion control synchronization system, NI TSN technology can not be less!
As mentioned earlier, in this TSN+OPC UA 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 supporting TSN, NI provides A demonstration program of a distributed motion control system, which combines the high reliability and ultra-low latency TSN ring network provided by the test bed, demonstrates the application scenarios of high-precision synchronization and real-time communication between multiple control nodes, and also validates the application scenario again. The TSN network guarantees a high degree of certainty and low latency for strict synchronization of industrial scenarios in complex environments.
Figure 2. Rahman Jamal (right), Director of NI Market Strategy and Technology, explains how NI TSN technology is applied to the entire TSN+OPC UA test bed.
According to Yi Lulu, an NI technology marketing engineer, in the demonstration program of this distributed motion control synchronization system, two NI CompactRIO combos constitute the Server-Client interconnect system, which is connected to a stepper motor and exercised motion control. Based on TSN technology, two control nodes can be reached<1us的同步精度. 在测试过程中, NI尝试在TSN环网中发送一系列干扰数据 (如视频串流数据) 时, 系统仍能保持控制操作的准确性与同步性. '这意味着, 基于TSN网络的流量调度功能, 该系统能够有效协调OT与IT数据传输的优先级, 保证控制信号传输的确定性和实时性. ' 易曦露补充道.

Cracking the Industrial Interconnect's Not Real-time & Inconsistent, NI Considers TSN+OPC UA's Experience
Focusing on the current status of industrial IoT development, from the perspective of interconnection, on the one hand, it is difficult for existing networks to meet the needs of industrial production for 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 this dilemma, the network system supported by information and communication technologies has become the key to the advanced development of industrial Internet of Things. As a group of protocol suites at the data link layer, the TSN of Ethernet uncertainty has been changed from the underlying architecture. Just like 'Arsenal': High bandwidth up to 1 Gbit/s; seamless integration of existing applications and interoperability of standard IT networks; deterministic transmission time of μs level and low latency of ns-level inter-node synchronization High synchronization, high security, and many other advantages all make TSN a methodological method to help IIoT accelerate the evolution of real-time.
Figure 4. NI believes that the continuous deepening of industrial interconnectivity has made high-bandwidth, real-time industrial field information interaction critical.
Although TSN is still in the technical stereotype testing stage, TSN has indeed developed rapidly in recent years. In particular, the Avnu Alliance in 2017, the Industrial Internet Alliance (IIC) and the OPC Foundation announced the introduction of OPC UA in TSN, and will be associated with the IT-OT industry. The news that leaders cooperate to promote the interoperability of industrial IoT and Industry 4.0 brings 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 semantic analysis at the application layer, and it provides A platform-independent service-oriented architecture provides the necessary infrastructure for the interoperability of the entire enterprise. It truly implements the interaction between different vendors and different devices. The unified channel established based on the two will not only Completely harmonizing the data link service standards is more likely to break the structure of traditional industries. Therefore, the industry generally believes that the integration of TSN and OPC UA will bring a whole new situation to the entire industry interconnection. At present, there are many people walking in front of the technology. The mainstream industrial automation company started to research and practice TSN+OPC UA. NI is one of them.
Looks at TSN as 'Industrial Interconnection' and the NI TSN 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 four major application scenarios for TSN: Pro AV, Automotive Control, Commercial The widest range of applications in the electronics field and in the future: All industrial areas that require real-time monitoring or real-time feedback. For companies that take root in the field of test and measurement, NI is an 'all-inclusive' company with a global customer base and business scope. Therefore, NI incubates. The focus of the product matrix is, on the one hand, to adhere to its own “software-centric” strategic core and in-depth multi-industry testing needs. On the other hand, it focuses on the emergence of 'new winds' in the industry. Form a new component that integrates new standards, new technologies, and flexibility to cater to the surge in market and user demand.
Therefore, in 2012, as a member of the International IIoT Alliance IIC, NI established the TSN task group, defined with many industry leaders such as Cisco and Intel, to standardize and promote the application of TSN. With the increasing maturity of TSN technology, Its further integration with OPC UA added a fire to its hot TSN: The industry's first batch of TSN products Intel, Broadcom, and Marvel TSN chips were successively launched; and Cisco, Hirschmann and other companies launched support for TSN The switch ... of course also contains a number of distributed edge computing platforms that NI continues to support in the past two years to support TSN:
In 2016, NI introduced the first IP67-rated industrial IoT, IC-317x series of industrial controllers for extreme environments, providing the highest level of processing power and connectivity for automated image processing and control applications;
On NIWEEK 2016, National Instruments released the CompactRIO cRIO-9035 and cRIO-9039 embedded controllers supporting TSN, providing the highest synchronization accuracy based on the synchronization of multiple real-time processors and FPGAs based on the TSN network.<100ns, 特别适用于搭建分布式控制系统及协调OT+IT流量调度;
NIWEEK 2017, NI once again introduced a new TSN-based CompactDAQ chassis - cDAQ-9185 and cDAQ-9189. As an Ethernet chassis dedicated to distributed measurement and synchronization, the highest accuracy of the CompactDAQ.<100ns, 多跳精度<1μs;
In late 2017, NI announced the introduction of a rugged, distributed, synchronized FieldDAQ device and introduced TSN into the most demanding test cells and outdoor environments. Because FieldDAQ integrates TSN, it can support most industrial I/O and control vendors (such as Bosch , Becca Lay and Schneider Electric) third-party TSN solutions;
Figure 5. National Instruments continues to extend the TSN product matrix, demonstrating strength in the global TSN ecosystem.
Of course, the new FieldDAQ is another product line besides industrial controllers, CompactDAQ and CompactRIO. Its introduction will further predict the further expansion of NI TSN products. In the future, NI will continue to vigorously promote the landing of TSN technology, and will Applied in more industrial interconnect scenarios.
Enclosed by the ecosystem, NI and industry benchmark companies jointly 'stir' the TSN air outlet
Internally, it focuses on accumulating its own technological advantages. Externally, it actively explores 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 member of the Board of Directors of the Avnu Alliance, or China. Members of the Executive Council of the Edge Computing Industry Alliance (ECC) play an important role in the global industrial interconnected ecosystem. In the field of TSN, NI is also actively creating its own 'TSN Ecology'.
As early as NIWEEK 2016, NI teamed up with Cisco and Intel to launch the world's first TSN experience technology platform. At the beginning of 2017, NI officially opened the Industrial IoT Lab. One of the operational focuses is TSN's flexible manufacturing. Cisco, Avnu Alliance, Intel and Xilinx and other industry giants demonstrated their cooperation on TSN networks through the demonstration of the TSN field test platform. At the end of 2017, NI was in the world's first TSN experience technology platform. Joined the new product of the year - the TSN-based CompactDAQ chassis. Through comparison with traditional UDP-based information transmission, it once again verified that TSN can maintain the prioritized transmission of time-sensitive data to achieve real-time and deterministic, ensuring that IT and OT are not Fusion.
In fact, as early as the end of last year at the 2017 Edge Computing Industry Summit, NI, who is a member of the Executive Council of the Edge Computing Industry Alliance (ECC) Council, has announced that it will cooperate with some of the core companies in the alliance and commit to leading foreign technologies. The advantages, such as TSN technology, combined with the uniqueness of the domestic vertical industry application scenarios, accelerate the landing of edge computing in various industries. Huawei is one of the founding members of ECC. I believe that in the near future, more will be seen. The application of NI-assisted applications falls on the Chinese industrial scene.
