Abstract

A network coupler is provided between a network, on which Ethernet messages can be transmitted, and a plurality of subscribers, the network being linked to an external interface of the network coupler and the plurality of subscribers being linked in series to a ring-type transmission path via an internal interface of the network coupler. For interchanging data, an Ethernet message received via the external interface of the network coupler is forwarded to the internal Ethernet interface of the network coupler and is output onto the ring-type transmission path, each subscriber connected to the internal interface interchanging the useful data intended for the respective subscriber with the Ethernet message circulating on the ring-type transmission path.
