Ep 20: OPC UA and Time-Sensitive Networking for Field Level Communication - Bhagath Singh Karunakaran (CEO, Founder - Kalycito )

Naturally, standard Ethernet does not guarantee real-time communication. So, to provide guaranteed cycle times and latencies for machine control and process automation using Ethernet, vendors implemented real-time Fieldbus protocols on top of it. Thereby creating a specialised type of Ethernet that is unusable for anything else, and causes fragmentation of industrial networks due to incompatibilities of Fieldbus protocols.But yet, for the success of Industry 4.0, what is required is one type of Ethernet network that is usable for both, executing time-critical OT processes, as well as for non-time-critical collection of data from machines in a standardised and vendor-independent manner.And this is what Time-Sensitive Networking (TSN) seeks to achieve.To understand how TSN is able to solve these challenges and its combination with OPC UA, I had a conversation with Bhagath Singh Karunakaran Bhagath is the CEO and Founder of Kalycito Infotech Pvt Ltd, India, an IIoT Software Solutions Company with Full-Stack device to cloud capabilities, and is a recognised thought leader in this space due to its pioneering effort to create an Open-Source ecosystem around OPC UA and TSN on real-time Linux. Including the world's first OPC UA Pub-Sub implementation.You can watch our conversation below, and here's the outline:✔️ What is TSN and how does it work✔️ Advantages of TSN over traditional Industrial Ethernet networks.✔️ Running Fieldbus Protocols on TSN✔️ Core elements of TSN for achieving time-deterministic communication✔️ Requirements for machines to participate in TSN network✔️ Importance of achieving field-level communication using OPC UA✔️ Combination of OPC UA with TSN✔️ The role played by OPC UA over TSN play in Industry4.0✔️ OPC UA Pub-Sub over TSN for Sensor to cloud communication✔️ Use cases of OPC UA over TSN in Manufacturing ✔️ Convergence of OPC UA over TSN and 5G for Industry 4.0✔️ Commercialised products implementing OPC UA over TSN✔️ Open Source crowd-funded OPC UA and TSN project
