DEVICE AND METHOD FOR FILTERING MESSAGES IN A SERIES-TYPE COMMUNICATION SYSTEM

摘要

The invention concerns series-type communication networks wherein the messages are transmitted to all the network nodes and comprise each an identifier code indicating the message content. The invention concerns a device and a method for filtering messages received so as to retain only messages addressed to a specific node. The method consists in: (a) establishing a list (48) of identifier codes (ID) corresponding to messages designed to be controlled by the microcontroller (32, MC); (b) assigning (50) to each identifier code (ID) of the list an index, (c) associating (44) with each message having an identifier code from the index list (FMI) assigned to it, (d) associating (66) with each index (FMI) an address in a storage (64), and (e) recording each message in the storage (64) at the address indicated by the index (FMI).
