Ethernet Powerlink
Ethernet Powerlink is a real-time protocol for standard Ethernet. It is an open protocol managed by B&R, ever since the dissolution of the Ethernet POWERLINK Standardization Group (EPSG) in 2023. It was introduced by Austrian automation company B&R in 2001.
This protocol has nothing to do with power distribution via Ethernet cabling or power over Ethernet (PoE), power line communication, or Bang & Olufsen's PowerLink cable.
