Abstract
A method of and network devices arranged for inquiring node device address information after commissioning of a network of communicatively interconnected node devices. A gateway device (2) broadcasts an inquiry message (MINQ) in the network, requesting each of the node devices (3, 4, 5) to transmit its node device address announce message (MANN), after a time delay (Δt1; Δt.2) from receiving the inquiry message (MINQ). The gateway device (2) transmits an acknowledgement message (MACK) to the node device addressed in a received node device address announce message (MANN), indicating that the respective node device address announce message (MANN) is received by the gateway device (2). A node device (4) may retransmit its node device address announce message (MANN) until receipt of an acknowledgement message (MACK). Received address information is stored by the gateway device (2) for control and communication purposes of the nodes in the network.
