Patent ID: 7483778

Claim:
An redundant configuration array comprising: a plurality of control devices interconnected via a first data bus for controlling a plurality of components of a transportation device, said control devices having redundant configuration with respect to a control function being provided, and a plurality of data bus isolating switches each assigned to one of said control devices which are of redundant configuration, each of said data bus isolating switches having an output port which is connected to a voltage supply of the assigned control device via signal line, connecting or disconnecting the assigned control device with the first data bus as a function of at least one evaluation signal, and is connected to a signal line of at least one further control device, wherein each of said at least one further control device transmits an evaluation signal to the data bus isolating switch which is assigned to another one of said at least one further control device, the evaluation signal being the result of functional checking of the at least one control device with respect to the another one control device, and the data bus isolating switch of the first redundant control device disconnects the first data bus as a function of the result of a logic circuit, at least one input signal of the logic circuit being formed by the at least one evaluation signal.
