A method of communications in a network interconnecting at least two power generators, each power generator being connected to said network by means of at least one interfacing device capable of sending and receiving communications frames, said frames comprising at least one piece of supervision data and at least one piece of information data. The method may include a step for sending during which the same pieces of information data are sent at least twice, two operations for sending frames to be sent that comprise identical pieces of information data being separated in time by a predetermined time interval, and a step for receiving, implementing a systematic elimination of one of the frames received when two frames comprising identical pieces of information data have been received.
