The overview display should include a plant mimic when a mimic may enhance personnel performance by (1) communicating functional relationships between components or (2) providing a means of organizing information that aids information retrieval and plant monitoring.
Additional Information:
Mimics are a prominent feature of overview displays for advanced control rooms. However, a mimic that is intended to provide a high-level indication of plant status may not be very informative to experienced operators because operators are very familiar with the functional relationships of the depicted systems and components. It may however, provide a useful framework for organizing plant information to support the operators in locating specific information and monitoring particular portions of the plant. A mimic format may also be valuable if it is used to depict functional relationships of lower-level components and parameters for which the operators are less familiar.
