All You Need to Know about PROFINET and TSN
Industry 4.0 has a lot of potential and it’s an exciting time to be involved in industrial automation. New solutions are taking shape and stand to make automation networks easier to manage, faster to run, and most importantly, provide value like never before. One of these key concepts is Time Sensitive Networking (TSN). TSN aims to make Ethernet deterministic by default and provide long term availability. This webinar will give an in-depth overview of TSN and how PROFINET over TSN will be implemented. Join us in this live webinar and learn the motivations of TSN, IEEE standards involved, technical details on synchronization, scheduling, streams, and much more!

Background on TSN
Ethernet communication is based on the best effort principle. Delays and throughput are situation dependent (empty network vs crowded network). With Ethernet, each device operates independently and on its own local clock making sending data in a precise time frame difficult.
TSN (Time Sensitive Networking) refers to a set of IEEE 802 standards that make Ethernet deterministic by default. TSN is a technology that sits on Layer 2 of the ISO/OSI Model. TSN adds definitions to guarantee delays and throughput. TSN integration into the Ethernet basic standard promises long time availability.
TSN evolved from the industry’s use of Audio / Video delivery and the need for more devices and synchronized communications. As more users connect up their devices to the Industrial Internet of Things and Industry 4.0 this also boosts demand. There are more devices on networks than ever before and more information being shared and analyzed. Therefore it makes sense that Ethernet has to perform better.
Some of the IEEE standards that make up TSN are:
- Enhanced synchronization behavior (IEEE 802.1AS)
- Suspending (Preemption) of long frames (IEEE 802.1Qbu)
- Enhancements for scheduled traffic (IEEE 802.1Qbv)
- Path control and bandwidth reservation (IEEE 802.1Qca)
- Seamless redundancy (IEEE 802.1CB)
- Stream reservation (IEEE 802.1Qcc)
