1. A method for handling latent anomalies, comprising:
- evaluating a plurality of data sources to detect existence of a latent anomaly; and
in response to detecting existence of the latent anomaly;
identifying a subset of a plurality of field devices that has potential to exhibit the latent anomaly; and
providing a self-test to each field device in the identified subset such that each field device in the identified subset can monitor for the latent anomaly and perform an action in response to monitoring the occurrence of the latent anomaly.

Abstract
Systems and methods for handling latent anomalies in field devices are described herein. When an anomaly is detected, the system can earmark the presence of the detected anomaly with a flag or other notification, and announce the existence of the anomaly to a user. In some embodiments, a self-test may be distributed to devices in the field that may be potentially affected by the latent anomaly so that those devices can monitor for the presence of the anomaly and take appropriate action if detected.

10. A field device for handling a latent anomaly, comprising:
-
a plurality of sensors; communications circuitry; non-volatile memory; and a processor operative to; receive a self-test module via the communications circuitry, wherein the self-test module comprises instructions that enables the field device to monitor for existence of a latent anomaly; store the received self-test module in the non-volatile memory; and periodically perform a self-test in accordance with the instructions to determine whether the latent anomaly exists within the field device. - View Dependent Claims (11, 12, 13)
