Abstract

A method is provided for extracting at least one usable data item flowing on a communication bus of a machine. The at least one usable data item is representative of a parameter of the machine, The method includes the following steps: receiving a configuration file including information relating to the coding of the at least one usable data item to be extracted; analyzing the information contained in the configuration file in order to enable the identification of the at least one usable data item to be extracted from all the data flowing on the communication bus; collecting the identified at least one usable data item; transmitting the collected at least one usable data item to a server that is remote from the machine.
