Abstract

The invention discloses an automatic method of assigning network address to a plurality of slaves connected in a master-slave network particularly in an emergency lighting installation. The automatic method assigns network address to the plurality of slaves based in one or more iterations. In an iteration, the method includes setting the plurality of slaves in commissioning mode by a master/control unit, generating a token by each of the slaves using a random number generation algorithm, determining a threshold by the master, responding by the slaves with the token matching the threshold, assigning a unique network address to the responding slave by the master in case of no collision among the slaves, increasing the threshold, and repeating the before-mentioned steps until all the slaves having token with no collision are assigned with the unique network address. The disclosed invention is simple to implement, requires no hardware change, and is scalable to any network size. The fully automatic method reduces time and manual labor significantly and eliminates error in assigning the network address in large network.
