METHOD OF COMPOSING MESSAGES FOR DATA-EXCHANGE PURPOSES AND/OR FOR THE SYNCHRONIZATION OF PROCESSES IN DATA-EXCHANGE SYSTEMS

摘要

A method makes it possible to constitute messages for the exchange of data and / or for the synchronization of processes in data processing installations. Each message contains at least elements relating to the beginning of the message (start-bit, SOF), to the identification (called identifiers) and to data. A bit field (IDE field, IDE bit) having at least one bit is used to characterize the length of the identifier.
