CONTROL DEVICE WITH CONFLICT DETECTION WITHIN A LIGHTING SYSTEM

A control device (100) comprises an interface (110) for connecting to an external communication; a bus power supply unit (120) that is configured to supply power to a specific-bus via the interface (110) when active; and an internal intelligence (130), which is configured to control at least the bus power supply unit (120). Hereby the interface (110) is connected to an external communication device (300, 400), which may be specific-bus communication device (300) or an other communication device. Hereby the interface (110) is adapted to detect an interface signal (200) at the interface (110), wherein the interface signal (200) is provided to the internal intelligence (130) via an internal communication (111), wherein the internal intelligence (130) is configured to evaluate, based on the interface signal (200) retrieved via the internal communication (111), whether the detected interface signal (200) is a specific-bus signal (210), which is characteristic of a connected specific-bus communication device (300), or an other control signal. Furthermore the internal intelligence (130) is configured to detect a conflict when an other control signal is evaluated and the bus power supply unit (120) is active, and upon detection of the conflict, to initiate an output of a signal and/or to deactivate the bus power supply unit (120).
