Abstract: A method for automatically assigning identifiers to controlled nodes of a fieldbus network, the controlled nodes comprising a plurality of electric motor drive systems, IO devices and/or feedback sensors, wherein the method includes the steps of setting the fieldbus network into a service mode; scanning the fieldbus network; decomposing the fieldbus network into linear branches and switches; scanning each linear branch; and assigning unique identifiers to the controlled nodes of the fieldbus network, wherein the identifiers include the relative positions of the controlled nodes in the fieldbus network and a node number. The disclosure is further directed at a fieldbus network including a plurality of controlled nodes, preferably electric motor drive systems, wherein the fieldbus network is provided for performing the method for automatically assigning identifiers.
