Abstract: There is provided a method for allocating node addresses in a computer network architecture and a computer network architecture for performing such a method. The computer network architecture comprises at least one master node and at least one slave node serially connected downstream of the master node. Each slave node includes a switch for connecting an upstream transmit line with a downstream transmit line at the slave node. When the switch is open, the master node and any upstream slave nodes are not connected via the transmit line to any downstream slave nodes. When the switch is closed, the master node and any upstream slave nodes are connected via the transmit line to any downstream slave nodes.

Abstract: Embodiments of the present invention relate to an a method, apparatus and computer program product for controlling the operation of a drive unit comprising a plurality of switching modules arranged to receive a DC electricity supply and generate an AC electricity supply for driving a load from the received DC electricity supply, the AC electricity supply being generated by the switching of the plurality of switching modules between a conducting state and a non-conducting state. The method comprises receiving one or more characteristics associated with each of the switching modules, comparing, for each switching module of the plurality of switching modules, a characteristic of the switching module with an equivalent characteristic associated with one or more other switching modules of the plurality of switching modules, and controlling a time period during which one or more of the plurality of switching modules are in the conducting state in accordance with a result of the comparison.
