International ClassG05F 001/00Foreign Application Priority Data1989-12-21 EPAbstractA control system for a plurality of appliances in distributed arrangement, in particular lighting fittings, having a command generator (1), a receiver (10) associated with each appliance (40), a control line (2) which connects the command generator (1) to each receiver (10), and a first memory (20, 23) in each receiver (10) in which an operational address (A2) for the associated appliance (40) can be stored. A control part (30, 50) is provided in each receiver (10) by means of which the appliance (40) associated therewith (30, 50) can be controlled by the command generator (1) if it (30, 50) has first been activated by selection of the operational address (A2) of the appliance (40) associated therewith. The control system for appliances that are to be in distributed arrangement is intended to make a particularly simple initiation of operations possible. This is achieved by the fact that the operational address (A2) in the first memory (20) of each receiver (10) can be written-in by electrical signals, and that an electrically readable second memory (21) is provided which contains a receiver-specific original address (A1).Other References
