A communication method between a collecting unit (5) and a plurality of control devices (7i), each of which is associated with at least an electrical device (1i), via the power line. Messages are exchanged between the collecting unit (5) and the control devices (7i), each of which contains at least: a progressive message number (Pr_N); an addressee identification number (ID_addressee); a portion of information content and/or executable commands (M4). A specific identification number (ID _i) is assigned to each control device and to the collecting unit. The messages are therefore addressable selectively to a specific control device via said addressee identification number. |
