Ship rudder control, so-called autopilot, includes a multiplicity of components connected with a bus interface to a CAN bus and via this also to each other. A further bus interface on each component of the control system is coupled to a separate, second bus, with the components being provided with unambiguous addresses and further information being assigned that mark the components as monitorable or non-monitorable. A device for emitting telegrams of component addresses and monitorability. A first comparator on all monitorable components start or switch off their own property as a monitoring component using the addresses of other components in received telegrams by comparison, and a second comparator on all monitorable components that use the number of received telegrams by comparison with the number of telegrams received on the other channel causing a change of the channel to that with the higher number of received telegrams under certain circumstances.

1. 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, andfirst 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. 2. The ship rudder control system according to claim 1, wherein the second bus is identical to the CAN bus. 3. The ship rudder control system according to claim 1, wherein all of the components are monitorable. 4. The ship rudder control system according to claim 1, wherein only two of the components are monitorable. 5. The ship rudder control system according to claim 1, wherein the bus control and bus connecting telegrams are always transmitted on both channels. 6. The ship rudder control system according to claim 1, wherein the control telegrams for the ship rudder are sent only on the channel that has been recognized by the active monitoring component as the primary channel and reported by means of a telegram. 7. A ship rudder control system comprising: multiple components each provided with a unique address and assigned information that individually establishes a monitoring status for each of the multiple components as either monitorable or non-monitorable ;a first bus interface on each of the multiple components coupled to a first, CAN bus so as to establish a first control channel;a second bus interface on each of the multiple components coupled to a second bus and establishing a second control channel;at least one device for emitting telegrams to the multiple components on both the first and second channels, with the telegrams including at least the addresses and monitoring status of the multiple components;a first comparator, provided for each of a first group of the multiple components having a monitorable monitoring status, for causing each of the monitorable components to either establish itself as an active monitoring component or switch off their own property as a monitoring component based on addresses of other ones of the components received in the telegrams; anda second comparator, provided for the first group of the components, for comparing numbers of received telegrams on the first and second channels to cause issuance of a channel change command to establish a select one of the first and second channels with a higher number of received telegrams as a primary channel, wherein a channel change command is only transmitted if a given component of the multiple components has previously determined itself to be the active monitoring component. 8. The ship rudder control system according to claim 7, wherein the second bus is identical to the CAN bus. 9. The ship rudder control system according to claim 7, wherein all of the components are monitorable. 10. The ship rudder control system according to claim 7, wherein only two of the components are monitorable. 11. The ship rudder control system according to claim 7, wherein the telegrams include bus control and bus connecting telegrams transmitted on both of the first and second channels. 12. The ship rudder control system according to claim 7, wherein the device further emits control telegrams which are sent only on one of the first and second channels which has been recognized by the active monitoring component as the primary channel.
