Abstract

A method is described for identifying communication-ready data bus subscribers connected to a local bus. The method comprises receiving, at a local bus master, at least one data packet transmitted via the local bus, wherein the at least one data packet received at the local bus master comprises an address of a communication-ready data bus subscriber among a plurality of communication-ready data bus subscribers in the local bus, wherein the communication-ready data bus subscriber is in a sequence of communication-ready data bus subscribers, and mapping of the received address by the local bus master to a relative position of the communication-ready data bus subscriber in the sequence of communication-ready data bus subscribers in the local bus. In addition, a local bus master of the local bus is described.

A method for identifying communication-ready data bus subscribers that are connected to a local bus, in particular a ring bus, the method comprising:

receiving, at a local bus master, at least one data packet transmitted via the local bus, the at least one data packet being received at the local bus master comprises an address of a communication-ready data bus subscriber among a plurality of communication-ready data bus subscribers in the local bus, wherein the communication-ready data bus subscriber is in a sequence of communication-ready data bus subscribers;
and
mapping, via the local bus master, the received address to a relative position of the communication-ready data bus subscriber in the sequence of communication-ready data bus subscribers in the local bus.

A local bus master of a local bus, in particular of a ring bus, the local bus master comprising:

a receiver to receive at least one data packet, the at least one data packet having an address of a communication-ready data bus subscriber from among a plurality of communication-ready data bus subscribers in the local bus, the communication-ready data bus subscriber being in a sequence of communication-ready data bus subscribers;
and
a mapper to map the received address to a relative position of the communication-ready data bus subscriber in the sequence of communication-ready data bus subscribers in the local bus.

Dependencies are inferred from the claim text.
