Abstract

For redundant message transmission in an industrial communication network having an arbitrarily meshed network topology, mutually independent paths are ascertained for a communication link that is redundant at least in sections between two network nodes within the industrial communication network, where the mutually independent paths comprise separate network nodes of a single communication network, and messages with duplicate identifiers are interchanged between transmission and reception units of communication devices of the industrial communication network in accordance with forwarding rules that correspond to the ascertained paths.
