METHOD FOR PROCESS OPERATORS TO PERSONALIZE SETTINGS FOR ENABLING DETECTION OF ABNORMAL PROCESS BEHAVIORS
First Claim
1. A method for setting drift warnings for monitoring processes that are applicable to a plant operating according to a process control and having a plurality of field devices, the method comprising:
- configuring a desired range for an acceptable drift range of a plant process;
setting a desired parameter value for the operating of the plant process;
detecting an actual parameter value of the plant process;
comparing the actual parameter value to the desired parameter value and the desired range; and
displaying an indication of a drift occurrence when the actual parameter value is within the desired range but different from the desired parameter value.

Abstract
A system, method, and an apparatus relating to automatically setting up pre-upset warning conditions for entire systems based on drifting parameters. The drifting parameters may provide monitoring to operate the process so that the upset condition is never reached, by allowing the operator can take actions so that the process remains in a stable state. The aim is to monitor and limit variations in parameters to enable the operator to achieve a much tighter control on the process and not allow the alarm to occur in the first place. Additionally, the important values may be displayed in context, and the operator may directly manipulate the values through a variety of touch input.
