Abstract
A system and method for monitoring device calibration. The system includes an asset management computer communicatively coupled to field devices. The asset management computer includes a processor connected to a memory device storing a field device drift identifying (FDDI) program. The FDDI program causes the asset management computer to statistically determine at least one process control limit from historical parameter data received from each of the field devices. The system continuously samples current parameter data received from each of the field devices and compares the current parameter data to respective ones of the process control limits for each of the field devices to determine whenever any of the current parameter data is outside the process control limit for identifying a first device drift for a first field device. Responsive to identifying the first device drift, an alert is generated that the first field device needs calibration.
