Abstract:
1. Control device having an assembly of system modules (S i ) in the form of at least one of field bus coupler modules, supply modules and input/output modules, which are arranged adjacent to one another and have terminal contacts in order to connect at least one of a system bus and a voltage supply terminal of a system module (S i ) to the subsequent system module (S i+1 ), characterized in that at least one bridge module (B) for the redundant voltage supply of the system modules (S i ) adjoining the bridge module (B) and for providing the system bus for the system modules (S i ) adjoining the bridge module (B) is provided at the end of the assembly of system modules (S i ), either opposite a field bus coupler (S 1 ) for coupling the system bus to a field bus or opposite a voltage supply module (S 2 ) for feeding a supply voltage for the connected system modules (S i ) if a system module (S i ) is removed from the sequence of system modules (S n ).
