Network, head subscriber and data transmission method

摘要

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.

1. A network having a control node and a plurality of network subscribers that are connected to the control node 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, and the closed ring-shaped data path transits through the network subscribers on both an outbound route and an inbound route, wherein the control node is designed to output data messages with identifiers onto the closed ring-shaped data path, wherein the network subscribers are designed to perform data interchange on the outbound route and on the inbound route with data messages transiting through on the closed ring-shaped data path, and wherein the head subscriber in the chain has a filter functionality, in order 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, and a transmission functionality, in order to output data messages onto the inbound route at prescribed instants.
