Abstract

An array of control devices having a plurality of control devices (1-3, 20-23) which are interconnected via a first data bus (4), in a means of transportation, control devices (1-3; 20-23) which are of redundant configuration with respect to a control function being provided, and in each case a data bus isolating switch (5) being assigned to the control devices (1-3; 20-23) which are of redundant configuration, the data bus isolating switch(s) connecting or disconnecting the data bus (4) as a function of an evaluation signal. In order to optimize the redundant array, each of these data bus isolating switches (5) is connected to a signal line of at least one further redundant control device (1-3; 20-23), a further redundant control device (2, 3; 21; 23) transmits an evaluation signal to the data bus isolating switch (5) which is assigned to a first redundant control device (1; 20; 22).
