  • Control system for a plurality of consumers arranged in a distributed manner, in particular for lamp operating devices, and methods for putting into operation
    Patent number: 8326441
    Abstract: In the case of a control system (1) for a plurality of consumers (10) arranged in a distributed manner, in particular for lamp operating devices, having at least one command generator (5), a control line (2) which connects the command generator (5) with each consumer (10) and associated with each consumer (10) a transmission and reception unit (11) provided for communication with the command generator (5), an operating address is allocated to each consumer (10) via which the consumer (10) can be contacted by the command generator (5). In accordance with the invention there is associated with each consumer (10) a memory element (20), separate from the consumer (10), for storing the operating address, wherein the memory element (20) is connected with the associated consumer (10) via the control line (2).
