The invention relates to a redundant serial bus and a method for its operation. In order to connect serial bus systems which are known per se but have no system- integrated redundancy means to one another by means of bus lines (11, 12) of redundant design, a redundancy means (3) is proposed which can be connected upstream and is connected between the bus communications interface (200) of a bus subscriber (2) and the redundant bus lines (11, 12). In this case, during operation, transmission always takes place on all the bus lines (11, 12), and a fault-free bus line (11, 12) is selected at the receiving end.
L'invention concerne un bus série redondant et un procédé permettant de le faire fonctionner. Selon l'invention, pour assembler des systèmes bus série connus en soi sans moyens de redondance intégrés au système, à l'aide de lignes de bus (11, 12) réalisées de manière redondante, il est proposé d'utiliser un moyen de redondance (3) pouvant être monté en amont qui est monté entre l'interface de communication de bus (200) d'un noeud (2) et les lignes de bus redondantes (11, 12). En cours de fonctionnement, l'émission se fait en permanence sur toutes les lignes de bus (11, 12) et, côté réception, une ligne de bus (11, 12) sans perturbations est sélectionnée.
