Abstract
A pair of wireless transceivers is disposed within a process control system to enable wireless communications between multiple devices within the process control system, such as between field devices, control units, user terminals, controllers, etc. In one embodiment, a process control system within an industrial process environment includes a process control field device that operates within the industrial process environment, a control unit adapted to provide control signals to the process control field device and a wireless transceiver pair including a first wireless transceiver connected to the process control field device and a second wireless transceiver connected to the control unit. The wireless transceiver pair wirelessly communicates one or more signals between the control unit and the process control field device to thereby provide wireless communications within the process environment.
