Wireless transceiver pair disposed within a process control system

A process control system within an industrial process environment, comprising:

• a first process control device located at a first location within the industrial process environment, for performing a process control function;
• a second process control device for making a process control decision relating to the process control function performed by the first process control device located at a second location within the industrial process environment, remote from the first location;
• and
• a radio frequency wireless transceiver pair including a first radio frequency wireless transceiver connected to the first process control device and a second radio frequency wireless transceiver connected to the second process control device, wherein the radio frequency wireless transceiver pair wirelessly communicates one or more real-time process control signals between the first location and the second location within the industrial process environment.

A method of providing communications within an industrial process environment, comprising:

• placing a first radio frequency wireless transceiver at a first process control device for performing a process control function located at a first location within the industrial process environment;
• placing a second radio frequency wireless transceiver at a second process control device for controlling at least one process parameter related to the process control function performed by the first process control device located at a second location within the industrial process environment, remote from the first location;
• and
• wirelessly communicating one or more real-time process control signals between the first location and the second location within the industrial process environment using the first and second radio frequency wireless transceivers to control the process control parameter related to the process control function performed by the first process control device.

A process control system disposed within an industrial process environment, comprising:

• a process control unit for controlling a process parameter;
• a plurality of field devices disposed within the industrial process environment for performing process control functions;
• and
• a network of three or more radio frequency wireless transceivers disposed within the industrial process environment, wherein each of the three or more radio frequency wireless transceivers is disposed at a different one of the field devices and the process control unit and wherein each of the three or more radio frequency wireless transmitters communicates signals to each of the other of the three or more radio frequency wireless transceivers whereby the process control unit controls the process parameter based on the communicated signals.
