Scheduled traffic, preemption, and time sync on standard Ethernet — what TSN guarantees, what it still needs, and where it meets the fieldbus.
EtherCAT
EtherCAT: high-speed Ethernet fieldbus with on-the-fly frame processing.
PROFINET, EtherNet/IP, EtherCAT, and TSN serve different masters. What each was designed for and how to tell them apart.
