ANALOG OUTPUT DIAGNOSIS TOOL
A system, method, and an apparatus related to a diagnostic tool to recognize abnormalities in the readings from the transmitter device. The diagnostic tool may diagnose the health of the transmitter device through review of an analog output and comparing it to a digital value. This comparison may be done periodically. The system includes a device for detecting field device operational anomalies of a field device in an industrial process. The system includes a storage medium operable to store program code and a processor operable to read the program code and operate as instructed by the program code. The program code includes acquiring an analog process variable (PV) value from the field device, acquiring a digital process variable (PV) value from the field device, calculating a difference value between the analog PV value and the digital PV value, comparing the difference value to a first threshold alert value, and issuing an alert to a user if the difference value exceeds the first threshold alert value.
