Abstract

A RFID transceiver interrogates RFID tags located on process components and provides identification data stored on the RFID tags to a process measurement device coupled to the process components. Based on the identification data received, the process measurement device configures itself to interpret data provided by the process components. Proper configuration allows the process measurement device to provide meaningful process data to a control room.
