MOTION SYSTEM TRENDS
Update on CC-Link IE TSN and motion-control applications
T
ime-sensitive networking (TSN) is not a protocol but an update to improve the IEEE Ethernet standard … and let engineers use general-purpose Ethernet for increasingly fast and sophisticated control and automation. It includes IEEE802.1AS defining its time-synchronization scheme and IEEE802.1Qbv defining its timesharing scheme. These make for punctual and reliable data and signal transmission to get synchronized and deterministic communications over Ethernet. In a recent conversation about TSN, Design World asked CC-Link Partner Association for the Americas director Timothy Lomax as well as CLPA-Americas manager John F. Wozniak, P.E. several questions about CC-Link IE Time Sensitive Networking (TSN) — a new network offering based on CCLink IE. CC-Link IE TSN supports integration of Operational Technology (OT) and IT while boosting the performance and functionality automated system communications. Here’s what Lomax and Wozniak had to say when specifically asked about how CC-Link IE TSN supports motion designs.

HOW DOES TIME-SENSITIVE NETWORKING (TSN) HELP MOTION APPLICATIONS? Lomax: Over the last few decades, motion control has shown incredible advancement. Today’s designs include internal processing of motion-control commands and related functions … and other hardware driving ever-increasing performance. Consider high-resolution encoders: Now these are to 24 and 25-bit resolution … and we’re constantly seeing higher resolutions from encoders for motion applications. Here and elsewhere, the trend towards higher Smart factories need to gather performance continues production information in unabated for servo real time; process it via edge motion … and these computing; and transmit benefit from components it onward to IT systems. and networking (TSN in Leveraging production-site particular) to synchronize data in this way necessitates disparate motion axes. a stable high-speed network such as CC-Link IE TSN.
