What is Ethernet?
Ethernet (IEEE 802.3) is the dominant technology for wired local area networks, and industrial variants such as TSN (Time-Sensitive Networking) enable deterministic real-time communication for safety-critical automation applications.
Technical Definition: The dominant technology for wired local area networks (LAN), defined in the IEEE 802.3 standard. Industrial variants such as TSN (Time-Sensitive Networking) enable deterministic real-time communication – a prerequisite for safety-critical applications in building and industrial automation.
Why it matters: Ethernet has become the universal physical layer in modern automation. It enables IP-based communication between all system levels, from field sensors to cloud analytics platforms, on a single network infrastructure.
HubMind’s view: We design Ethernet networks that are both robust and properly segmented – ensuring that an IT network problem cannot propagate into the OT control layer.
