Communication procedure for configuration and / or interrogation purposes and system that puts it into practice

摘要

Procedure for temporary communication between a configuration, interrogation and / or diagnostic device, which is master during the communication time, and an intelligent, configurable and / or replaceable product, of the actuator, pre-actuator, sensor or detector type, which is a slave during the time period of the communication, said product (2) including at least one processing unit (3), a direct current supply line or input (4) and at least one output line and / or output interface (5), said product (2) being connected, in current operation in its usual application, to at least one power and evaluation system (1 '), by its line or power input (4) and by its output line or interface (5), a procedure characterized by the fact that the product (2) is, in current operation, independent of the device (1), to join it as a slave product (2) to the master device (1), while after the product (2) is disconnected from the system (1 ') and then, for the purposes of a configuration, a calibration, a parameterization, an interrogation or also a test or a diagnosis, to transmit to the product ( 2) interpretable data by its processing unit (3) through the supply line (4), modulating the supply voltage, and transmitting data back, from the product (2) to the device (1) ), through the output line or output interface (5) attached to said device (1).
