Abstract

The present invention relates to a network for an aircraft, comprising a master device and a plurality of slave devices (3a, 3b, 3c) connected in series in a daisy-chain arrangement. Each of the slave devices (3a, 3b, 3c) has an associated unique identifier taken from a predetermined ordered sequence of identifiers. The master device (2) is adapted to transmit polling data packets (8) along the series of slave devices (3a, 3b, 3c), each including one and only one identifier, and the polling data packets (8) are transmitted in successive sequences, each including for each of the slave devices (3a, 3b, 3c) one and only one polling data packet (8) and including the polling data packets (8) in the order defined by the predetermined sequence of identifiers. Each of the slave devices (3a, 3b, 3c) comprises a first data interface (4) for connection in an upstream direction, a second data interface (5) for connection in the downstream direction, and a processing unit (6) adapted to compare for each received polling data packet (8) the identifier thereof with the identifier of the respective slave device (3a, 3b, 3c), and output a response data packet (9) to the master device (2) if the two identifiers match, and forward the polling data packet (8) to the second interface (5) at least if the two identifiers do not match. Each processing unit (6) comprises an adjustable time delay element (7) adapted to delay the output of the response data packets (9) by an adjustable delay period (19). For each of the slave devices (3a, 3b, 3c) the delay period (19) is set to a value depending on the relative position of the respective slave device (3a, 3b, 3c) in the daisy-chain arrangement, such that it continuously decreases from slave device (3a, 3b, 3c) to slave device (3a, 3b, 3c).
