How Time-Sensitive Networking (TSN) is Transforming Industrial Automation
At the ARC Industry Forum 2025, Greg Orloff of IIoT World sat down with Thomas J. Burke, the Global Director of Industry Standards at Mitsubishi Electric, to discuss the evolution of industrial connectivity, focusing on CC-Link technology and the role of Time-Sensitive Networking (TSN) in unifying disparate industrial networks.
Challenges in Industrial Networking
Industrial environments are filled with disparate devices and networks, creating challenges in interoperability. Traditionally, each system—whether from Siemens, Rockwell, or Mitsubishi—required its dedicated physical wiring, increasing installation costs and complexity.
TSN addresses these challenges by providing an interoperable, unified network where multiple protocols can coexist. Originally developed for audiovisual research, TSN has been successfully adapted for industrial automation. It allows networks such as PROFINET, EtherNet/IP, and CC-Link to run seamlessly on a single network.
What is Time-Sensitive Networking (TSN)?
TSN is a breakthrough IEEE standard that enables deterministic communication over Ethernet. It allows low-latency, high-reliability data exchange across different industrial protocols, supporting real-time applications in:
- Manufacturing automation
- Process control
- Smart factories and Industry 4.0
- Industrial Internet of Things (IIoT)
Key Benefits of TSN in Industrial Automation
TSN delivers several advantages that drive its adoption across industries:
- Seamless Network Convergence
By enabling multiple protocols to run on a single network, TSN reduces the need for dedicated wiring. This not only streamlines network infrastructure but also significantly lowers costs.
- Improved Data Sharing for IoT and OT Integration
A critical aspect of digital transformation is IT/OT convergence. TSN allows IT (Information Technology) and OT (Operational Technology) networks to communicate efficiently, providing real-time access to operational data for better decision-making.
- Sustainability in Industrial Automation
Sustainability is becoming a top priority across industries. TSN supports energy-efficient operations by optimizing network resources, reducing hardware redundancy, and improving process efficiency.
- Enhanced Reliability and Performance
TSN guarantees low-latency, high-priority data transmission, essential for applications like robotics, motion control, and process automation where real-time responsiveness is critical.
Adoption and Growth of TSN
Since 2018, the CC-Link Partner Association (CLPA) has been integrating TSN technology into industrial automation. Currently, over 3,800 products from 700+ vendors support TSN, reflecting its rapid adoption across sectors.
How to Get Involved with TSN Technology
Organizations such as the CC-Link Partner Association (CLPA) and the OPC Foundation provide valuable resources and collaboration opportunities for those looking to explore TSN further. Former OPC Foundation president Tom Burke emphasizes TSN’s role in enhancing interoperability and driving digital transformation.
