The invention relates to a method and an apparatus for allocating subscriber device addresses in a Profinet IO network. It is an object of the invention to demonstrate a novel, further way of ensuring the allocation of station identifiers, which are needed in Profinet IO systems and on the basis of which the subsequent automatic subscriber addressing is performed by ascertaining and associating logical and physical addresses, in a simple and error-resistant manner. The invention thus provides for the development of a Profinet IO compatible subscriber device having a selector switch such that the station identifier is obtained directly from the respective setting of the selector switch in combination with a firmly prescribed group identifier which is specific to a respective particular group of subscriber devices.
