TSN Technology Update: impact on factory automation
SOURCE: SIEMENS
Time Sensitive Networking is changing the landscape of Industrial Ethernet protocols and network solutions with the possibility of new levels of convergence and interoperability. In this special report, industry experts weigh in on the benefits of TSN, what it offers and the expected timeline and impact on factory automation.
A converged network architecture based on IEC/IEEE 60802 (TSN Industrial Automation profile) is a benefit that TSN will bring to industrial automation. TSN TECHNOLOGY OFFERS TANTALIZING possibilities for the world of Industrial Ethernet automation and control networking. Never before have we seen enabling technology standards offer this kind of disruptive change, intermingled with the new requirements put into focus by the emergence of the IIoT and Industry 4.0. The promise of Time Sensitive Networking (TSN) leveraging existing Industrial Ethernet network protocols, wireless TSN leveraging 5G communications, and technologies such as OPC UA TSN creates a preview of a new emerging landscape for industrial networks. In this report, IEB offers comprehensive coverage and provides the perspective of industry leaders, along with a picture of how TSN is moving ahead in a quest that most agree will ultimately transform smart manufacturing. The broad range of perspectives demonstrates the potential of the technology, and illustrates how TSN will create new solutions for a wide range of applications.

Focus on converged networks Expected emergence of IEC/IEEE 60802
The ability for TSN to help achieve a converged network architecture based on IEC/IEEE 60802 (TSN Industrial Automation profile) is a primary benefit that time-sensitive networking will bring to industrial automation applications. Along with that is delivering a plug & produce technology solution, as defined by Industrie 4.0, into the realm of smart manufacturing. “The main innovation possible due to the availability of Time Sensitive Networks is the converged network,” Günter Steindl, Enterprise Architect at Siemens Digital Industries told IEB. “Thus, many automation companies like Siemens, ABB, Mitsubishi, Rockwell and others are started together the standardization of a TSN industrial automation profile as a joint IEC/IEEE 60802 project.” Based on these definitions, devices with different middleware--such as PROFINET and OPC UA--can share in Time Sensitive
Network quality of service guarantees. This converged network includes wireline and wireless, including Industrial 5G or Wi-Fi communication. Altogether, it represents the networking pillar “Vernetzung” from Industrie 4.0 and thus, fulfills the communication requirements of Plug & Produce.
Structured network design
According to Steindl, structured network design defining TSN Domains as areas of the industrial network, for production machines, production cells or production lines allow separation of concerns. These converged networks provide a series of benefits for industrial communication: • Scalability: machine to production line • Provide guaranteed quality of service • Protection of network resources • Excellent network and connection diagnosis • Support for splitting of application and communication
