field device for use in an industrial process control or monitoring system, and method for communicating in a field device for use in an industrial process control or monitoring system
FIELD DEVICE FOR USE IN A METHOD OR MONITORING CONTROL SYSTEM FOR COMMUNICATION OF PROCESS IN AN INDUSTRIAL AND FIELD DEVICE FOR USE IN AN INDUSTRIAL PROCESS CONTROL OR MONITORING SYSTEM A field device (14) for use in a system Industrial process control or monitoring (10) connects to a two-wire process control loop (16). The mesh (16) carries data and provides power to the field device (14). RF circuits (22) in the field device (14) are provided for radio frequency communication. A power source (18) energizes RF circuits (22) using power received from the two-wire process control loop (16).
