The invention relates to a method for simplified allocation of station addresses to communication users in a bus system, and communication users in a bus system. A first communication user, which can automatically transmit to the bus, can allocate data to a station address, said data clearly identifying another communication user, or characterizing a station address as non-occupied. An additional communication user who has already sent a data packet with clearly identifying data to the first communication user in an earlier communication cycle by means of said communication user and who receives a data packet comprising data in a later communication cycle, whereby said data does not clearly identify said communication user, can automatically alter the station address thereof in a station address characterized as not being occupied.
