In a network, a control node is connected to a plurality of network subscribers via a closed ring-shaped data path, wherein the network subscribers form a chain, starting from the control node, with a head subscriber as a termination for the chain. The ring-shaped data path transits through the network subscribers on an outbound route and an inbound route, wherein the network subscribers are designed to perform data interchange both on the outbound route and on the inbound route with data messages circulating on the ring-shaped data path. The control node is additionally designed such that it outputs data messages with an identifier on the data path, wherein the head subscriber has a filter function to use a prescribed identifier to block the further transport of data messages with the corresponding identifier on the inbound route following transit of data messages through the head subscriber on the outbound route. The head subscriber further has a transmission function and additionally outputs a data message on the inbound route at a prescribed moment.
