46. A process control monitoring system comprising:
-
a plurality of radio frequency identification devices associated with respective ones of a plurality of process control elements of an industrial plant;
an interrogator configured to implement wireless communications with respect to the radio frequency identification devices, wherein the interrogator is configured to output a plurality of wireless interrogation signals which identify the radio frequency identification devices; and
wherein the radio frequency identification devices are individually configured to receive the wireless interrogation signals, and for individual ones of the wireless interrogation signals, to determine whether the individual wireless interrogation signal identifies the individual one of the radio frequency identification devices and to output a wireless reply signal comprising information of the respective one of the process control elements responsive to the individual wireless interrogation signal identifying the individual one of the radio frequency identification devices. - View Dependent Claims (47, 48, 49, 50, 51, 52, 53, 54, 55)
