Multi-station bus system having means for polling and updating of globally relevant information, in particular a station address, and station for use in such system

摘要

A communication system has multiple and uniformly weighted station interconnected by a shared digital bus. A particular station comprises globally relevant information, and, with a predetermined maximum recurrence time, transmits a data packet representing such item to any other interested station. If unanimous counter signalization occurs, the item is in order, other wise updating thereof is undertaken. The unanimity is either by positive signalization, or by default.
