Abstract
A system for preserving process variable data relating to the operation of a process is provided. The system is adapted to preserve process variable data obtained before, during, and after the occurrence of an abnormal situation or event. The preserved process variable data maybe communicated from smart field devices or other intelligent equipment relating to the control of the process to a process controller or other higher level control device. The process controller or other higher level control device may then cause the preserved data to be displayed for an operator or other maintenance personnel. The preserved data may also be provided to other process control modules or abnormal situation prevention systems for further analysis to develop methods for preventing the abnormal situation from recurring in the future, or for taking additional steps based on the abnormal situation data to minimize or prevent a further deterioration of the process operation.
