摘要: A LAN elevator network includes (a) a pair of redundant car buses for exchanging signals with control system elements, (b) group the by means car-group bridge, and (c) building buses, which exchange messages controller, group-building bridge. Communication among all nodes on bus, bus occurs single protocol. Each communications element communicates coprocessor including transmitter receiver.
