Method and device for automatically assigning addresses to a plurality of modules interconnected by a communications network topology complex.

摘要

A method for automatically assigning addresses to a multiplicity of interconnected modules via a network tree topology (1 to 6) linked to a central unit (UC), determining the address of each module (M1 to M15) from the address the module situated immediately upstream in the network relative to the central unit, and is assigned an address, issuing on the network address thus determined by the upstream module in an allocation message address, comprising a phase automatic search module that has no allocated address situated closest downstream in the network, a module already having an address, this phase including for each module not having any allocated address: - reception (50) , by the downstream module, the address assignment message and the shot (52), by the same, a current TIME n whose duration is greater the weaker is the receiving level of the received message, - if, at the end (54) of the timing, the downstream module does not detect (53) in the network any message address capture, issuing (56), by the same, a trap message address containing the address to be allocated, storing (57), by the same, the address received as module address, determination (20 to 29), by the same, the address of the module that is not allocated address situated closest downstream in the network and the shot (30), by the same phase automatic search for the module not has allocated address situated closest downstream in the network.
