Because of its high precision, low latency and high reliability, time sensitive network (TSN) has received the attention of the industrial control field with high network requirements, and has changed from a technology under development to an essential technology for control systems in just a few years. As the time sensitive network gradually extends from the theoretical research stage to the physical industry application, the importance of TSN technology in the industry is increasing significantly.

Promote the application of TSN technology and help China’s manufacturing industry accelerate towards digital intelligence. On August 24, 2023, the TSN and Industrial Intelligent Technology Forum co-sponsored by Zhonghua Industrial Control Network and Bowen Creative Exhibition (Shenzhen) Co., Ltd. was successfully held in Shenzhen Convention and Exhibition Center (Futian). At the meeting, the representatives of Schneider Electric, Dongtu Technology, Huawei, ADI, and Can State Information made wonderful sharing. In the same period, there are four major exhibitions such as 2023 ELEXCON Shenzhen International Electronics Exhibition and Embedded Systems Exhibition, with 500+ exhibitors on stage to show global industry dynamics and future technology trends.

As a global digital transformation specialist in energy management and automation, Schneider Electric is a world leader in the energy, infrastructure, industrial control, building automation, data center and networking markets. Schneider Electric industrial communication standards manager Gong Yanjie through the industrial user pain points, TSN introduction, the value of TSN to the industrial network, TSN industrial application evolution path, all aspects of the TSN industrial application value analysis and implementation path outlook. He said that in terms of products, TSN ease of use needs to be improved, and TSN terminal equipment sometimes still needs to specify the type of TSN switch; In terms of standardization, the IEEE TSN specification has matured, and the IEC/IEEE 60802 standard is expected to be released in 2025; In terms of ecology, the application value of TSN is gradually emerging, and TIACC will ensure the layer 2 interoperability of “xxx over TSN” end-side devices. In terms of chips, the second batch of TSN product list has included a number of domestic manufacturers of TSN chips, CNC universal controllers, and eventually in the case of existing Ethernet chips with similar costs, TSN function support will be achieved.

Dongtu Technology is a global industrial Internet technology innovation leader, committed to promoting the industrial Internet in the communication protocol, industrial APP software hosting platform and control hardware platform three levels of technical unity. Zhu Ying, Solution Director of Dongtu Technology, shared end-to-end time-sensitive network solutions and applications, and focused on the first TSN chip independently designed by Dongtu Technology in China – KD6530 autonomous controllable TSN chip. Starting from the functional architecture, TSN features, built-in CPU, reliability, testing and certification of KD6530, Zhu Ying elaborated TSN end-to-end solution, TSN terminal solution, and TSN gateway solution, fully demonstrating the innovation achievements of domestic enterprises leading the development of TSN.

IT and OT are two different technology fields, which stand for information technology and operations technology respectively. The development and introduction of time-sensitive network TSN technology has laid a foundation for accelerating the integration of IT and OT. Chen Lihao, a senior engineer at Huawei, shared technologies for open architecture IT/OT converged networks. He grasped the pain point that traditional architecture could not adapt to new digital intelligence applications and remote centralized control requirements, demonstrated the superiority of IT/OT converged network, and answered his unique views on six questions of TSN, including the core task of TSN, queuing scheduling mechanism defined by TSN, and time-gated scheduling.

ADI is a leading global semiconductor company that Bridges the physical and digital worlds to enable breakthrough innovation at the intelligent edge. Yu Keyong, Industrial Automation Application Engineer Manager at ADI, shared ADI’s TSN Switch solution for the Industrial Internet, introduced the next generation TSN Switch products ADIN6310 and ADIN3310, system configuration and software drivers, and gave a live demonstration. It is worth mentioning that this is the first public appearance of the ADIN6310 and ADIN3310 in China.
