Abstract
A control system having a host computer and one or more control computers connected to an interface for control of a process or machinery. The control computers are capable of automatically initiated network address assignment and configuration when powered up after installation. The network address is based on a location identifier situated in the interface that corresponds to a specific connection thereof to the control computer. The control computer reads the location identifier from the interface and requests a network address. The host computer assigns the network address based on the location identifier. Configuration of the control computer then proceeds. The procedure applies to newly installed control computers, whether first time installment or a replacement for a failed control computer.
