装置。 a data collection unit that collects process data of a plant; an instrument failure diagnosis unit that diagnoses a failure of each instrument of the plant from the process data collected by the data collection unit; and a diagnosis result of the instrument failure diagnosis unit and the data. a general abnormality diagnosis section that diagnoses an abnormality other than the instrument failure diagnosed by the instrument failure diagnosis section from the process data collected by the collection section; a diagnosis result of the general abnormality diagnosis section; and a diagnosis result of the instrument failure diagnosis section. and a diagnostic result output display section for outputting and displaying a diagnostic result output display section, and the general abnormality diagnosis section outputs and displays the process value of the instrument whose failure has been detected when the instrument failure diagnosis section detects the instrument failure, and the general abnormality diagnosis section outputs and displays the process value of the instrument whose failure has been detected by the instrument failure diagnosis section. A plant abnormality diagnosis device characterized in that abnormality diagnosis is performed by excluding collected process data.
