A method of operating a control system, ideally for a fan installation, has a master control unit connected to a data bus or network and a plurality of slave devices also connected to that data-bus, each slave device having a databus extender permitting the connection thereto of a further slave device. Each slave device has an initial default address and the data bus extender is turned off. The master control unit requests a response from any slave device having the default address and on a slave device responding to that request, the master control unit assigns a new address within a predefined address space and the databus extender of that slave device is then turned on. These steps are repeated until the master control unit does not determine the presence of any further slave devices. Preferably the method steps are performed on power up. |
