Abstract
A local network including no more than eight stations, each station being able to be both a source and a sink for data, and, thus being able both to receive and emit a message, the stations being interconnected by a serial bus and providing data to a distributed data base, which data is renewed cyclically under the control of a request generator that emits requests in the form of binary messages. The stations have addresses in the form of bytes respectively constituted by bytes of binary numbers representing powers of 2 in the range 0 to 7, a binary message emitted by the request generator containing the addresses, of all the stations designated to be sinks for the emitted binary message, in the form of a composite byte constituted by an OR UNION of the addresses of the stations designated to be sinks, a station thus observing that it is chosen as a sink by performing an AND INTERSECTION between the composite byte and the station's own address byte.
