Patent ID: 8346395

Claim:
A ship rudder control system including a multiplicity of components that are connected with a bus interface to a CAN bus and to each other comprising: a further bus interface on each component of the control system that is coupled to a separate, second bus, the components being provided with unambiguous addresses, and further information being assigned to the components that mark the components as monitorable or non-monitorable, at least one device for emitting telegrams to all components that transmit, in addition to the address of the components, also the monitorability or the non-monitorability and that are arranged for the reception of signals from other components on the CAN bus and for outputting control information on at least one of the CAN bus and the second bus, and first comparison means on all monitorable components that start or switch off their own property as monitoring component using the addresses of other components in the received telegrams by comparison, second comparison means on all monitorable components that use the number of received telegrams on a channel by comparison with the number of telegrams received on another channel to cause a change of the channel to that with the higher number of received telegrams, a channel change command being only transmitted if the component has determined itself previously to be an active monitoring component by activating the second comparison means by activity of the first comparison means.
