A method for addressing a slave device in a network system comprising a master device and a plurality of slave devices. The slave devices have a common default address in an unaddressed state and the master device and the plurality of slave devices are connected in chain via a power line and a communication line, wherein each slave device is indexed by an index greater than or equal to 1, the slave device of index 1 being connected to the master device, wherein, to address the slave device of index k, k being equal to or greater than 2, the method first instructs the slave device of index k&#x2212;1 to activate the power supply of the slave device of index k via the power line, and then, it sends, to the common default address on the communication line, a command to change the common default address of the slave device of index k to a unique address of index k. Therefore, at each iteration, there is only one unaddressed slave device in the network.
