Abstract: A control module for a human-machine dialogue system, the system including a plurality of human-machine dialogue members, each human-machine dialogue member including a functional element that includes at least one electrical contact and/or a signalling indicator. The control module is configured to operate in a write mode to attribute a state to each signalling indicator of each human-machine dialogue member and in a read mode to read a state of the electrical contact of each human-machine dialogue member.

Abstract: A method is provided for monitoring a communication between a transmitting equipment item and a receiving equipment item, the transmitting equipment item transmitting control frames (TC_i) toward the receiving equipment item. The method makes it possible to optimize the frequency of transmission of diagnostic frames (TDx_i), thereby making it possible to avoid saturating the communication link and causing an overconsumption of electrical energy, while guaranteeing a high reliability concerning the state of the communication.

Abstract: A method for monitoring a communication between a transmitting equipment item and a receiving equipment item, said transmitting equipment item transmitting control frames (TC_i) to the receiving equipment item. The method makes it possible to take account of the fact that the control frames (TC_i) are not necessarily transmitted at fixed frequency and to adapt the transmission of the diagnostic frames (TDx_i) to the frequency of transmission of the control frames. Upon a significant variation of this transmission frequency, if no diagnostic frame has been transmitted between the two control frames, the instant of transmission of the next diagnostic frame will take account of this aspect.
