Abstract

A method for operating an industrial automation system communication network, wherein at least one control unit controls functions of a plurality of communication devices for operating a communication network that includes plurality of communication devices, where the communication network is subdivided into a plurality of partitions which each include a plurality of end nodes as service access points and predeterminable shares of system resources of communication devices, where guaranteeable service quality parameters, which may be mapped in a multi-dimensional service quality parameter matrix for each partition, are determined for each data transmission within the partitions, by a pair of end nodes and in a manner dependent on direction, where each partition is assigned uniquely to a respective user together with the guaranteeable service quality parameters, and where potentially available system resources and authorizations for each respective user are specified by the assigned.
