Abstract

Provided is diagnostic equipment for selecting a data item to be used for a diagnosis on the basis of operation history information of an operator. Plant diagnostic equipment receives a measurement signal of a plant and an operation signal of a time of operation performed by an operator using an external input device and displays a state of the plant on an image display device as display information. The plant diagnostic equipment includes a measurement signal database for storing the measurement signal of the plant, an operation history database for storing the operation signal of a time of the operation performed by the operator using the external input device, and learning means for extracting a data item to be used for a diagnosis of the plant from the display information displayed on the image display device by the operation performed by the operator using the external input device when an abnormality in the plant occurs.
