Abstract:
1. A method for operation of a data bus to which multiple bus participants each with a respective serial number specific to them are connected, comprising the steps of: connecting a new bus participant to the data bus; generating a request bus message by the new bus participant, said message containing a preliminary participant identification number as an identifier, said number being derived from a serial number of the new bus participant, the request bus message being sent to a master processor system for assigning a final participant identification number for the new bus participant after receipt of the request bus message with the preliminary participant identification number, the final participant identification number having fewer digits than the serial number of the new bus participant; using the final participant identification number by the new bus participant as an identifier for further bus messages from said new bus participant; and upon connection of said new bus participant, a time offset for said request bus message from said new bus participant to said master processor system is determined in addition to the preliminary participant identification number, said time offset being derived from the serial number of said new bus participant so that a simultaneous transmission of request bus messages from said new bus participant and any other new bus participants to said master processor system with the same preliminary participant identification numbers is avoided.
