Abstract
In a method or system for operation of a data bus to which multiple bus participants each with a respective serial number specific to them are connected, a new bus participant is connected to the data bus. A request bus message is generated by the new bus participant, the message containing a preliminary participant identification number as an identifier derived from a serial number of the new bus participant. The request bus message is sent to a master processor system for assigning a final participant identification number for the new bus participant after a receipt of the request bus message with the preliminary participant identification number. The final participant identification number has fewer digits than the serial number of the new bus participant. The final participant identification number is used by the new bus participant as an identifier for further bus messages. 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.
