Abstract
A method for initializing a communication network in a train including a plurality of cars, the network comprising a train bus, a train bus master on one of the cars and a train bus slave on each other car connectable to the train bus master by the train bus for communicating with the train bus master. The method includes determining whether the one car with the train bus master is located at one end of the train or is in the middle of the train. The method further includes transmitting first messages between the train bus master and each train bus slave, respectively, located in one direction for assigning an address to each train bus slave located in that one direction and acquiring data at the train bus master uniquely identifying the respective train bus slaves in that one direction. The method further includes transmitting, when the determining step determines that the one car is located in the middle of the train, second messages between the train bus master and each train bus slave, respectively, located in an other direction for assigning an address to each train bus slave located in the other direction and acquiring data at the train bus master uniquely identifying the res…
