<p>A method is provided for dynamically assigning an address to a device in a control system. The control system has a master controller that is coupled to the device via a network. When a device is connected to the network, the device sends an address request message over the network. The address request message is received at the master controller, and the master controller assigns a control area network address to the device. The control area network address includes a system number and a device number. Furthermore, the master controller removes the assigned control area network address from an available device number list stored in the memory of the master controller. The master controller also associates a physical connection address of the device with the assigned control area network address. An address designation message that includes the assigned control area network address is sent from the master controller to the device. The message is received by the device, and the device determines the assigned system number and device number. The device then writes the assigned system number and device number by the device into its memory.</p> |
