Abstract: A method for autoconfiguration of a plurality of nodes in a linear network allows extracting the address and position of each node. The method includes applying an identifier field for transmitting to the bus the bit sequence of the identifier of a chosen node. Then for at least for the first node to the last but one node, a field comprising a predetermined bit sequence is applied. The field comprises dominant bits, so a current is transmitted. Then, a further field is applied for transmitting any stored direction bit associated to that node and obtained in any previous iteration. The iteration continues by choosing a node different from a node chosen in any previous cycle, starting the communication, until all nodes are identified.

Abstract: A method for autoconfiguration of a plurality of nodes in a linear network allows extracting the address and position of each node. The nodes are identified by a unique identifier. The method comprises choosing a node in a network and extracting its identifier, and for the first node to the last but one node, transmitting a current in the network from the chosen node, and reading the direction of the current flowing through at least the nodes not chosen in previous iteration cycles. The identifier is linked with the direction of the current for said not chosen nodes, obtaining the position of said not chosen nodes relative to the chosen node. These steps are repeated by choosing a different node not chosen before. Autoconfiguration is finished when the identifier of each node is extracted, and the physical position of each node is determined.
