Wireless communications within a process control system using a bus protocol
First Claim
1. A process control system for use within a process control environment, comprising:
- a process control field device;
a control device adapted to receive a sense signal from or to provide a control signal to the process control field device;
a first wireless transceiver communicatively connected to the process control field device; and
a second wireless transceiver communicatively connected to a second process control field device or to the control device;
wherein the first wireless transceiver is adapted to communicate with the second wireless transceiver using a bus protocol.

Abstract
An apparatus provides wireless communication between multiple devices within a process control system, such as between field devices, control units, user terminals, controllers, etc., using a wireless bus protocol. In one embodiment, a process control system for use within a process control environment includes a plurality of process control field devices that operate within the process environment, and a control device adapted to receive a sense signal from or to provide a control signal to one or more of the plurality of process control field devices. First and second wireless transceivers are communicatively connected to different ones of the process control field devices and the control device and communicate with one another using a bus protocol, to thereby provide wireless communications within the process control system.
