Unlock cutting-edge applications with TSN


John Browett, General Manager at the CC-Link Partner Association (CLPA), looks at how Time-Sensitive Networking supports the next big developments in industrial communications technologies. 

Continuous development and breakthrough technologies are advancing industrial communications, enabling them to reach new heights and ultimately writing the next chapter of the digital era. One key innovation unlocking significant opportunities and cutting-edge applications is Time-Sensitive Networking (TSN).

Control engineers worldwide now have more tools than ever available to create seamlessly interconnected plants – and the best is yet to come, thanks to TSN. In effect, this technology complements standard industrial Ethernet to offer extremely accurate synchronisation, traffic prioritisation and scheduling. Thanks to these functions, TSN can handle multiple types of data and their different priorities over a single network infrastructure. As a result, it is possible to share information and generate more holistic business intelligence while reducing cabling requirements, which can reduce network complexity, capital expenditure and operational expenses.

Therefore, we can confidently state that adopting TSN marks the first crucial step in creating unified, comprehensive network architectures that serve all types of automation. Even more, the power of TSN to drive convergence enables engineers to implement many more future-oriented industrial communications technologies, even beyond Ethernet. These provide a pathway to the realisation of the Connected Industries of the future as well as the creation of smart, flexible and proactive supply chains where all players can share key insights with their partners and end users.

Cable Multitasking

For example, reducing the number of cables required to create factory or enterprise-wide networks will continue and may even lead to the complete transition towards wireless technologies. These are evolving to support industrial applications, in addition to the information technology (IT) world, the consumer marketplace, and home automation systems.

Expanding the use of wireless technologies in the operational technology (OT) domain, the latest 5G and 802.11 Wi-Fi standards can support ultra-reliable low-latency communications (URLLC) to meet the need of manufacturing facilities. Adding TSN functions can lead to communications with bounded low latency, low jitter and extremely low data loss. TSN-wireless hybrids may be the key to creating network architectures with unprecedented levels of flexibility while increasing data accessibility and availability to support a wide range of activities, such as enhanced remote monitoring.

What the future holds doesn’t end here. While 5G adoption is still underway, work to develop the next-generation wireless solution, i.e. 6G, has already begun. These networks are expected to support even more heterogeneous applications, such as virtual and augmented reality, artificial intelligence (AI) infrastructures and the metaverse.

Driving Change 

All these communications technologies can help companies advance the digital transformation of their businesses and even their entire supply cycles. Given this will also be enabled by TSN, forward-looking businesses that want to keep up with the latest, most promising trends to drive their competitiveness should look at adopting new frameworks that are compatible with the technology.

CC-Link IE TSN, the earliest open industrial Ethernet to combine gigabit bandwidth with TSN functions, offers the ideal platform to support this transition. In addition to being the first of its kind, developed by an organisation committed to delivering innovative solutions to its users, CC-Link IE TSN provides a reliable system that leverages proven protocols and technologies. The open industrial network is already being used in readily available automation devices, empowering companies to set up future-proof machines and facilities now.
