Abstract: System and method for determining a probability of an alarm being shelved using a weighting algorithm taking into account relevant factors or characteristics associated with an industrial process. Support for rendering a decision is provided, including determining an estimated time duration before the alarm is un-shelved if the alarm is likely to be shelved, a rationale for the alarm to be shelved, and relevant information supporting the rationale. A machine learning model learns from operator actions relating to alarms to capture the knowledge of the operator and to update or refine the weighting algorithm.

Abstract: System and method of securing a process control instrument of a process control system. An authorization server is configured to authenticate the process control instrument based on a unique secure code provided to the server in response to the process control instrument entering an enhanced secure mode as determined by a switch setting. In response to being authenticated in the enhanced secure mode, the process control instrument is configured to operate in a configuration state in which an authorized user is granted access to configure the security details of the process control instrument.
