Abstract: A redundantly operable communication system for an industrial automation system, wherein a first communication device is redundantly connected to a third communication network connection of first and second network infrastructure devices, the second communication device is redundantly connected to a third communication network connection of a third and fourth network infrastructure device, where the first and third network infrastructure device and the second and fourth network infrastructure devices are interconnected via their first and second communication network connections such that, while the first and second communication device identify data frames to be redundantly transmitted via a first indicator, the first and third network infrastructure devices and the second and fourth network infrastructure devices identify data frames to be redundantly transmitted via a second or third indicator that differs from the first indicator, and reject data frames received on the third communication connection and identified via the second or third indicator.

Abstract: 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.
