Use TSN when you need deterministic Ethernet communications for Industrie 4.0 and IIoT applications

The smart factories envisioned by Industrie 4.0 are not in our future. They’re here, now and they rely heavily on networked equipment. Everything needs to be networked. In the past, industrial and factory applications relied on an entire zoo of different and incompatible networking “standards” and some of these were actually standards. Today, the networking standard for Industrie 4.0 and IIoT applications is pretty well understood to be Ethernet—and that’s a problem because Ethernet is not deterministic. In the world of factory automation, non-deterministic networks are a “bad thing.”


Enter TSN (time-sensitive networking).


TSN is a set of IEEE 802 substandards—extensions to Ethernet—that enable deterministic Ethernet communications. Xilinx’s Michael Zapke recently published an article about TSN in the EBV Blog titled “Time-Sensitive Networking (TSN): Converging networks for Industry 4.0.” After discussing TSN briefly, Zapke’s article veers to practical matters and discussed implementing TSN protocols within the Xilinx Zynq UltraScale+ MPSoC’s PS (Processing System) and PL (Programmable Logic) using Xilinx’s 1G/100M TSN Subsystem LogiCORE IP, because you need both hardware and software to make TSN protocols work correctly.


Note: If you’re attending the SPS IPC Drives trade fair late this month in Nuremberg, you can see this IP in action.
