METHOD FOR SERIAL ALLOCATION OF ADDRESSES AND MONITORING THE ADDRESS ALLOCATION IN A BUS SYSTEM

The invention relates to a method for serial allocation of addresses and monitoring the address allocation in a bus system, comprising a bus with a controller and several addressable users connected thereto, whereby the controller (12) assigns an address to a user (16-22), for addressing in each address allocation cycle and the controller (12) emits a start signal to begin each address allocation cycle. Each user (16-22) still to be addressed records the number of receiver start signals up to the addressing thereof and records, during the address allocation cycle in which said user receives an address from the controller (12), a number value corresponding to the number of start signals received up to that point. The controller (12) requests the number value stored for the addressed users (16-22) after addressing the last of the users not yet addressed, or after finishing a number of address allocation cycles, corresponding to the number of users (16-22) and checks the plausibility of the addressing by means of said number value.
