Abstract: A method includes obtaining different measurements of voltages across terminals of a field device coupled to an I/O loop. The voltage measurements are associated with corresponding loop currents flowing through the I/O loop. The method also includes identifying a baseline loop resistance measurement of the I/O loop using the voltage measurements and the loop currents. The method further includes obtaining additional measurements of voltages across the terminals of the field device. The additional voltage measurements are associated with additional corresponding loop currents flowing through the I/O loop. The method also includes identifying additional loop resistance measurements of the I/O loop using the additional voltage measurements and the additional loop currents. In addition, the method includes detecting a problem with the I/O loop based on the baseline loop resistance measurement and the additional loop resistance measurements.

Abstract: Methods and systems for monitoring process equipment such as field devices. A QR code can be associated with a field device, wherein the QR code contains data that identifies the field device, and also includes process data regarding the field device, the location of the field device, and maintenance information, installation information and fault information associated with the field device. The QR code can then be scanned and decoded in order to retrieve the data for use in in monitoring and maintaining field devices in the context of a connected plant.
