5 Summary

When properly engineered, Gigabit Ethernet local area networks with IEEE 802.1Q-2018 TSN features can achieve time synchronization comparable to EtherCAT. In both systems, the greatest sources of error will be the hardware design of the clocking and physical level transceivers. By utilizing the standard TSN feature of EST, it is possible to precisely place frames on the wire without relying on vendor proprietary implementations of TTS. These findings are significant for industries that require precise and reliable communication, such as motion and motor control. In addition, the ability to precisely place frames on the wire demonstrate that TSN capable hardware can be used to improve current EtherCAT Main implementations as well as paving the way for TSN solutions to be a viable alternative to EtherCAT in certain use cases.
