PROFINET vs EtherNet/IP vs EtherCAT: a selection guide
Compare PROFINET, EtherNet/IP, and EtherCAT on synchronization, cycle time, topology, tooling, and ecosystem — and pick the protocol your plant can live with.
PROFINET
PROFINET and PROFIBUS: real-time industrial Ethernet from PI.
PROFIBUS to PROFINET migration without stopping the plant
Gateways, proxies, cable reuse, GSD-to-GSDML transitions, and a cutover sequence that keeps brownfield I/O alive.
Choosing an industrial network topology
Star, line, ring, and redundant designs explained through failure modes, commissioning effort, latency, and the maintenance team’s real needs.
Time-Sensitive Networking: a primer for automation engineers
Scheduled traffic, preemption, and time sync on standard Ethernet — what TSN guarantees, what it still needs, and where it meets the fieldbus.
A field guide to industrial Ethernet
PROFINET, EtherNet/IP, EtherCAT, and TSN serve different masters. What each was designed for and how to tell them apart.
