Determination of data bus users of a local bus

摘要

A method for determining communication-ready data bus subscribers (7a, 7b,..., 7n) connected to a local bus (6) is described. The method comprises receiving, at a local bus master (3), at least one data packet (22a, 22b, 22c), transmitted via the local bus (6), wherein the at least one data packet (22a, 22b, 22c) received at the local bus master (3) an address of a communication-ready data bus subscriber (7a, 7b, ..., 7n) from a number of communication ready data bus subscribers (7a, 7b, ..., 7n) in the local bus (6), wherein the communication ready data bus subscriber (7a, 7b , ..., 7n) within an order of the communication-ready data bus users (7a, 7b, ..., 7n) and assigning the received address to a relative position of the communication-ready data bus user (7a, 7b, ..., 7n) within the Order of the communication-ready data bus users (7a, 7b,..., 7n) in the local bus (6) by the local bus master (3). Furthermore, a local bus master of the local bus (6) is described.
