Abstract

A plant wireless access point (PWAP) is disclosed that bridges communications between a field communicator and a plant automation network. The PWAP may facilitate provisioning of new plant devices into a plant automation wireless network using the field communicator, and may also facilitate the field communicator performing various functions regarding one or more plant devices connected to the plant automation network. The PWAP may allow a field communicator to access information from the plant automation network and/or from other sources via the plant automation network such as the Internet. In addition, the PWAP may determine a location of one or more field communicators relative to the PWAP and/or other devices connected to the plant automation network.
