Zusammenfassung:To provide an abnormality factor determination device and a display device of the same, capable of preparing for a response to an abnormality before determining an abnormality factor.SOLUTION: In the display device of the abnormality factor determination device in a control system for controlling a device by data communication over a network, determination by the abnormality factor determination device includes a primary determination and a secondary determination. In the primary determination, it is determined which each data corresponds to an attack determination condition indicating that a plurality of pieces of data received by the data communication are being attacked over the network as a progress of determination or a failure determination condition indicating a device failure. In the secondary determination, a cause of abnormality is determined based on the primary determination. The display device displays the progress of the primary determination when the abnormality factor determination device is performing the primary determination, and displays a result of the secondary determination when the abnormality factor determination device completes the secondary determination.SELECTED DRAWING: Figure 2 【課題】異常要因の判定前に、異常への対応を準備できる異常要因判定装置およびその表示装置を提供すること。【解決手段】本発明の実施形態によれば、ネットワークを介したデータ通信により機器を制御する制御システム内の異常要因判定装置の表示装置において、この異常要因判定装置による判定には一次判定と二次判定とがあり、一次判定では、判定の途中経過としてデータ通信により受信した複数のデータがネットワークを介して攻撃を受けていることを示す攻撃判定条件または機器の故障を示す故障判定条件のどちらに該当するかをデータ毎に判定し、二次判定では、一次判定に基づき異常の要因を判定し、表示装置は、異常要因判定装置が一次判定中の場合には一次判定の途中経過を表示し、異常要因判定装置が二次判定を完了した場合には二次判定の結果を表示する。【選択図】図2
