  • Publication number: 20080253303
    Abstract: The invention discloses a method to determine a relative position of devices in a network, and to a network of devices for carrying out the method. In a network with a power cable (10) connected to a plurality of devices (A-I), one needs to know the physical position thereof in order be able to control them efficiently. This used to be done manually, but the present method proposes to select a device to send a detection signal with increasing amplitude across the network, and to measure the time each of the remaining devices detects the detection signal. Due to signal losses in the network, a more remote device will show a longer detection time. Collecting the various detection times enable a control unit (12) to determine the relative position of all, or at least part of, the devices (A-I).
