World premiere of TSN+OPC UA smart manufacturing test bed
Recently, more than 20 international organizations and industries such as Industrial Internet Industry Alliance (AII), Avnu Alliance, Edge Computing Industry Alliance (ECC), Fraunhofer FOKUS, Huawei, National Instruments (NI), Schneider Electric, and B&R. The “Industrial Connectivity Half of the World†formed by well-known manufacturers, at the world's largest industrial exhibition - Hannover Industrial Fair in Germany in 2018, jointly released the TSN (Time Sensitive Networking) + OPC UA Intelligence that includes six major industrial interconnection scenarios. Make a test bed.
Cracking the Industrial Interconnect's Non-real-time & Ununited Testbeds By simulating rich real-world smart manufacturing scenarios, the live demo demonstrates the key technology point of smart manufacturing - TSN+OPC UA, which is predictive maintenance, data analysis, and machine Key drivers of new technologies such as learning and artificial intelligence can help industrial companies improve efficiency, such as reducing downtime, increasing overall equipment efficiency, and reducing overall costs.
Focusing on the current status of industrial IoT development, from the perspective of interconnection:
â— On the one hand, it is difficult for existing networks to meet the needs of industrial production with high security, high real-time, and high reliability;
â— On the other hand, due to the lack of a unified standard interface, they are generally faced with difficulties such as poor interoperability.
Therefore, 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 located at the data link layer, the TSN that changes the Ethernet uncertainty from the underlying architecture is like a "descendant":
â— High bandwidth up to 1Gbit/s;
â— seamless integration of existing applications and standard IT network interoperability;
â—Deterministic transmission time of μs level and low delay/high synchronization of ns-level inter-node time synchronization;
â— Many advantages, such as high security, make TSN become a methodology to help IIoT accelerate the evolution of real-time.
In November 2012, the IEEE 802.1 Task Force formally changed the name of AVB (Ethernet Audio Video Bridge Technology) to TSN, and also established four major application scenarios for TSN: ProAV, automotive control, and commercial electronics. The most widely used application in the future: All industrial fields requiring real-time monitoring or real-time feedback.
Although TSN is still in the technical stereotype testing stage, TSN has indeed grown 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 work with the IT-OT industry. The news that leaders have cooperated to promote 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 high certainty and low latency of network communication; OPC UA solves the problem of application layer semantic parsing, and it provides A platform-independent, service-oriented architecture provides the necessary infrastructure for interoperability across the 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 OPC UA will bring a whole new situation to the entire industry interconnection.
As smart manufacturing places higher demands on flexible production and more and more cross-platform and cross-industry applications are required, large-scale real-time industrial communication networks pose serious challenges for operators. The test bed released this time is based on the OPC UA standard, which ensures that multiple devices from different manufacturers can easily collaborate in one system; Huawei TSN switches provide high-reliability and ultra-low latency industrial control networks. The TSN+OPC UA test bed incorporates SDN (Software Defined Network) technology to achieve priority sorting based on precise time, unified transmission of real-time and non-real-time data, and truly realize the connection between machines, people, and objects. "Open the last mile of the Industrial Internet."
Integrating IT and OT to promote digital transformation in the industry <br> In this release of the smart manufacturing test bed, Huawei's six major industrial interconnection scenarios with multiple vendors are:
â— The TSN for Predictive Maintenance (TNI) with AII;
â—Synchronization with the motor created by the National Instruments of the United States;
â— "Racing game" created with Hollysys;
◠“Draw motion control†created with Linmot;
â— "Synchronization of LED" with Schneider Electric;
â— "OPC UA Over TSN" with B&R.
These six scenarios verify the high determinism and low latency of TSN networks in complex environments and ensure strict synchronous motion control in industrial scenarios. In addition, Spirent Communications' test equipment is used to generate TSN and non-TSN traffic to verify the benefits of the new industrial network architecture and services.
NI (National Instruments) exhibited a demonstration program for motion control synchronization scenarios at this conference. Based on two NI CompactRIO embedded controllers that support TSN, NI provides a demonstration solution for a distributed motion control system that combines the high reliability and ultra-low latency TSN ring network provided by the test bed to demonstrate multiple controls. The application scenarios of high-precision synchronization and real-time communication between nodes also once again verified the high degree of certainty and low latency of the strict synchronization of TSN networks in a complex environment.
In this demo solution of the distributed motion control synchronization system, two NI CompactRIOs are combined to form a Server-Client interconnect system that 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, this system can effectively coordinate the priorities of OT and IT data transmission, and ensure the deterministic and real-time nature of control signal transmission."
The joint launch of the TSN+OPC UA 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.
Alexander Willner, PhD, Fraunhofer FOKUS, Europe's largest applied scientific research organization, said: "Since the introduction of programmable logic controllers (PLCs), industrial automation processes have been greatly optimized. The convergence between OT (Operations Technology) and IT (Information and Communication Technology) is exciting and will bring interesting innovation experiences. The combination of OPC UA and TSN enables real-time information exchange and interoperability in the industrial field. The scenarios demonstrated in the test bed demonstrate our respective technological advantages and we are looking forward to the future of digital networks."
Dr. Luo Jijun, director of product management and marketing of Huawei’s European solution, said: “In the future, there will be billions of devices connected to the Internet in the industrial sector. Traditional industrial Ethernet cannot tolerate huge amounts of data transmission, and a new architecture is needed to meet high bandwidth. , high-speed and mass connectivity, etc. In the future, Huawei will intensify cooperation with more organizations and manufacturers in the industry to jointly build an industrial Internet ecosystem, promote the continuous improvement of TSN technology and standards, and truly realize “full-mesh communications†under the TSN network. Promote the digital transformation of the manufacturing industry."
In the industrial field, the deep integration and innovation of OT and ICT has greatly enhanced the automation level of the manufacturing process, making personalized customization possible, and the production model, supply chain, and service are also changing. The launch of the TSN+OPC UA smart manufacturing test bed was a big one, which gave us a glimpse of the future of the industrial Internet.
TSN technology has attracted more and more automation vendors and ICTs around the world. Xiaobian specially noticed that Siemens, a low-key member of TSN, was present at the Hanover show. Klaus Helmrich also announced for the first time that Siemens will officially support TSN. From this point of view, with the participation of these international giants, TSN is no longer far from the actual industrial applications!
