INDUSTRIAL AUTOMATION LEADERS ENDORSE TSN
T
SN in an enhancement to standard Ethernet that ensures inherent determinism through a number of IEEE 802.1 specifications. When looking at industrial Ethernet, two of
these standards emerge as key to drive Industry 4.0 applications, IEEE 802.1AS and IEEE 802.1Qbv, which handle time synchronisation and traffic scheduling, respectively. Together, these functions provide
deterministic performance, making it possible to share multiple types of data traffic on the same network, driving convergence and the merge of information technology (IT) and operational technology (OT). Thomas Rodenbusch-Mohr, product manager at Belden, explains: “TSN is standardised within the IEEE, making the technology extremely important, in my opinion. Secondly, you can do real-time applications based on this open standard, so you don’t need to be locked into a proprietary ecosystem. Finally, you can save on infrastructure costs because you can run IT and OT traffic on the same network without disturbing your critical control data packets, for example.”
DRIVING THE LARGE-SCALE ADOPTION OF TSN In order to deliver competitive products and help customers fully reap the benefits of TSN, industrial automation vendors have been developing a variety of devices that leverage the technology. When it comes to implementing it, the market leading solution is CC-Link IE TSN,
By enabling convergent communications at the core of Industry 4.0 applications, Time-Sensitive Networking (TSN) is being regarded by market leaders as a must within the Connected Industries of the future. With a rapidly growing demand for the technology, the number of industrial automation vendors offering TSN- compatible devices continues to grow.
the first open industrial Ethernet combining gigabit bandwidth and TSN functions. Simon Seereiner, head of Product Management SAI & IE at Weidmüller, comments on the drive towards the launch of CC-Link IE TSN compatible devices: “TSN is an exciting technology, specifically for real-time deterministic communications. We, at Weidmüller, started very early to work together with the CLPA on the implementation of the necessary requirements for TSN communications and connectivity. Together with the organisation, we have certified the full range of RJ45-based patch cables as well as field attachment connectors.” Masaki Kawazoe, director of commercial marketing Factory Automation at Mitsubishi
Electric, agrees on the value of the TSN technology and the gains achievable through convergence: “Mitsubishi Electric has already a lot of existing solutions compatible with CC-Link IE TSN. Customers can easily integrate all our products and CLPA’s partner products together. They can also have these devices communicate with the IT level through TCP/IP communications on the same one network. Customers can also integrate safety solutions on this network. This is very powerful and beneficial to customers.” The need for devices that can leverage TSN is
also felt by end users, as Sascha Lambauer, strategic product manager at Weidmüller,
