Title: METHOD FOR OPERATING AN INDUSTRIAL AUTOMATION SYSTEM COMMUNICATION NETWORK COMPRISING A PLURALITY OF COMMUNICATION DEVICES, AND CONTROL UNIT
Abstract:
According to the invention, for operating an industrial automation system communication network comprising a plurality of communication devices, at least one control unit controls functions of several associated communication devices. A specifiable proportion of system resources of the associated communication devices is made available to the control unit for a specifiable resource use duration. The control unit determines for data streams, a path between an associated first communication device and an associated second communication device via associated third communication devices. The control unit checks, for each data stream, whether the latter is exclusively associated with a transmission queue along the determined path in at least one third communication device. If the checking process is negative, it is determined whether each data stream can be exclusively associated with at least one transmission queue by means of a modified allocation of the transmission queues or by modifying the path of at least one transmission queue.
