Protocol for autoconfiguration of communication network

A method of autoconfiguration of a plurality of nodes connected via a bus forming a linear network, each node being identified by an identifier comprising an identifier bit sequence, the identifier being unique for each node connected to the linear network, the method comprising interchanging, in each iteration cycle, a data frame including a frame bit sequence between the plurality of nodes, the frame bit sequence being divided in fields of consecutive bit strings, the iteration cycle comprising:

• applying an identifier field for transmitting to the bus the identifier bit sequence of the identifier of a chosen node,
• at least for the first node to the last but one node, applying a field comprising a predetermined bit sequence comprising dominant bits for transmitting a current to the bus from the chosen node, allowing reading a direction of the current through at least each remaining node of the plurality that was not previously chosen, wherein the reading is performed by said remaining node, the direction being represented by a value of a bit being a direction bit, thus allowing storing a direction bit associated to a position of the chosen node relative to said at least each node that was not previously chosen,
• applying a further field for transmitting any stored direction bit associated to that node and obtained in any previous iteration,
• performing a further iteration cycle of the three previous steps by choosing a node different from a node chosen in any previous cycle, and starting again a communication, until all nodes of the linear network are identified,
• further comprising storing the direction bit obtained during each iteration cycle linked together with the identifier of the chosen node which transmits the current in said each iteration, further comprising determining a physical position of each node relative to the rest of nodes connected to the linear network, based on the stored direction bits obtained from the nodes and linked chosen nodes in each iteration cycle, wherein determining the physical position is performed by a plurality of nodes, further comprising comparing the physical position obtained by at least two nodes.
