Abstract

Disclosed is a monitoring and/or control device (1) having an assembly of system modules (S.sub.i) in the form of field bus coupler modules, supply modules and/or input/output modules, which are arranged adjacent to one another and have terminal contacts in order to connect a system bus (4) and/or a voltage supply terminal of a system module (S.sub.i) to the subsequent system module (S.sub.i+1). At the end of the assembly of system modules (S.sub.i), a bridge module (B) is provided opposite a field bus coupler (S.sub.1) for coupling the system bus (4) to a field bus (7) and/or opposite a voltage supply module (S.sub.2) for feeding a supply voltage for the connected system modules (S.sub.i) for the redundant voltage supply of the system modules (S.sub.i) adjoining the bridge module (B) and/or for providing the system bus (4) for the system modules (S.sub.i) adjoining the bridge module (B) if a system module (S.sub.i) is removed from the sequence of system modules (S.sub.i).
