Package: inet.node.ethernet

EthernetPlcaHost

compound module

A network node designed specifically for Ethernet 10BASE-T1S multidrop networks. It extends StandardHost with specialized Ethernet interfaces that support the Physical Layer Collision Avoidance (PLCA) protocol.

10BASE-T1S is a single-pair Ethernet standard defined in IEEE 802.3cg-2019 that allows multiple nodes to share a common bus topology. PLCA is a media access control mechanism that enables deterministic access to the shared medium without collisions, making it suitable for industrial automation and automotive applications.
