摘要： A receiver network component operates in a communication network of an automation system. The component receives data messages sent redundantly by transmitter network components of the communication network and rejects duplicates of an already received data message. Interoperability of network components from different manufacturers is ensured even for device-redundant transmitter network components and redundant transmission of data messages is achieve with comparatively low complexity. The receiver network component is prompted by reception of a current data message from one of the transmitter network devices to check whether a data message with identical useful data has already been received from another transmitter network component. The data message is processed if it is received for the first time and it is rejected as a duplicate if it is a data message with such useful data that have already been received in an earlier data message from another transmitter network component.
