Abstract: The present invention relates to commissioning in the presence of multiple networks. A network node, which is expected to join a second network, joins a first network and enters a second state from a first state once it has joined the first network. Once it has received from the first network a message to leave it, it enters a third state from the second state. The network node entered the third state becomes responsive with respect to the first network and/or the second network by receiving a dedicated message to join network or is unresponsive with respect to the first network. Then, it enters the first state from the third state once the network node has received the dedicated message from a coordinator of the first network after closing the first network and/or from a coordinator of the second network, or upon expiry of a timer.

Abstract: A drive circuit driving a first switching element, including: a first diode with a cathode terminal connected to a first switching element gate terminal; a second switching element with a first terminal connected to a first diode anode terminal, a second terminal connected to a first switching element gate terminal, a third terminal connected to a first switching element source terminal; a third switching element with a drain terminal connected to the first diode anode terminal, and a source terminal connected to the first switching element source terminal; a parallel circuit; and a drive transformer having a coil, one end connected to the drain terminal, the other end connected to the third switching element gate terminal, and connected to the third switching element source terminal, one end of the parallel circuit connected to one coil end, the second diode cathode terminal connected to the other end of the coil.

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 (?t1; ?t.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.
