METHOD AND APPARATUS FOR DYNAMIC ADDRESS ASSIGNMENT
First Claim
1. An apparatus for controlling address assignment in a communication network, wherein a unique address is assigned to each device of the network, said apparatus comprising a network driver and being adapted to send an address request containing a unique identification of said apparatus to a predefined address of said network via the network driver, and wherein said apparatus is adapted to take over the role of an address assignment master in response to the receipt of a non-acknowledging response created by the network driver upon observing no reaction to said address request.

Abstract
The present invention relates to an address assignment procedure where an address request containing a unique identification is sent to a predefined address of a network, and the role of an address assignment master is taken over in response to the receipt of a non-acknowledging response to the address request. Standard intelligent building blocks can thus be used to create a large product portfolio. The intelligent building blocks are connected to each other via a network and addresses can be assigned without needing additional process steps, human interaction or factory/field-service tooling.
