The method applies to an electronic module comprising a gateway to a communication bus suitable for receiving digital signal frames comprising, in particular, a frame-identifier field and a data field, an identifier discriminator being provided in the module in order to authorise the acquisition by the latter of the data contained in frames comprising a predetermined identifier, this discriminator comprising a memory zone assigned to the latter. A signal frame, the data field of which contains the predetermined identifier, and the identifier field of which contains an image of the initial state of the memory zone, is initially applied to the gateway of the module to the communication bus, in such a way that the identity then established by the discriminator between the initial content of this zone and the identifier field of the frame, authorises the loading into the said memory zone of the predetermined identifier inscribed in the data field of the frame. Application to an assembly of interconnected electronic modules in a multiplex communications network placed on board an automotive vehicle.
