Method and radio communication system for an industrial automation system, radio subscriber station and serialization unit

Abstract

A radio communication system in which first and second communication devices are linked redundantly to an industrial communication network, wherein the first communication device is connected to a serialization unit connected to a network infrastructure device, first and second radio base stations are connected to the network infrastructure device, the second communication device is indirectly or directly connected to a first and a second radio subscriber station, the first radio subscriber station is connected to the first radio base station whilst the second radio subscriber station is connected to the second radio base station, where the serialization unit replaces destination addresses in data frames conveyed by the first communication device with addresses of the first or second radio subscriber stations, where the radio subscriber stations replace destination addresses corresponding to their address in data frames conveyed via the radio base stations with original destination addresses replaced in the serialization unit.
