COMMUNICATION METHOD FOR THE PURPOSE OF CONFIGURATION AND/OR INTERROGATION, AND SYSTEM USING SAME

摘要

The subject of the present invention is a method of communication, in particular with a view to configuration, calibration, parameterization, interrogation or else a test or a diagnostic, between a master device and a slave product comprising at least one processing unit and one DC power supply line or input, as well as, where appropriate, at least one output line and / or output interface. Method characterized in that it consists in transmitting to the product data which can be interpreted by its processing unit via the supply line and by modulating the supply voltage.
