Communication Device for a Redundantly Operable Industrial Communication Network and Method for Operating the Communication Device

摘要

A communication device for a redundantly operable industrial communication network comprises at least one first and one second transmitting and receiving unit each having an interface for a network connection of the industrial communication network. A signal processing unit is connected to the first and second transmitting and receiving units. A singly linked network node is connected to the signal processing unit via a coupling element. The signal processing unit is connected to the coupling element via a first and second interface. In this case, the first interface is provided exclusively for communicating data packets received by the first receiving unit, while the second interface is provided exclusively for communicating data packets received by the second receiving unit.
