Abstract
A method and apparatus for a communication system for facilitating communication on the network. Identification of a network device, preferably a controller or IO device, is based on a physical location of device. Accordingly, the physical location of the network device is determined by a device locator. The physical location of each network device is used to associate a network identifier, i.e., network address, with the network device to facilitate network communication with other devices. The network identifier is associated with the network device in response to a signal transmitted from the network device requesting the network identifier. A mapping method is used to convert a map of physical locations to one or more address tables so as to allow a controlling station to associate the network identifier with the network device for routing messages to and from the device based on the physical location.
