Abstract

A network for an aircraft including a master device and slave devices connected in daisy-chain arrangement series. Each slave device has a unique identifier. The master transmits polling data packets along the slave devices, each including only one identifier. Polling data packets are transmitted in successive sequences, each including for each slave device only one polling data packet and including the polling data packets in a predetermined order. Each slave device includes a first data interface for connection in an upstream direction, a second data interface for connection in the downstream direction, and a processing unit to compare for each received polling data packet the identifier thereof with the identifier of the respective slave device, and output a response data packet to the master device if the two identifiers match, and forward the polling data packet to the second interface at least if the two identifiers do not match.
