Method for process operators to personalize settings for enabling detection of abnormal process behaviors

A system comprising at least one device for setting drift warnings for monitoring processes in a plant operating according to a process control and having a plurality of field devices, the system comprising:

• at least one non-transitory computer readable medium operable to store program code;
• at least one processor operable to read said program code and operate as instructed by the program code, the program code 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.
