Anlagen-Diagnoseapparat

摘要

According to a plant diagnostic apparatus of the present invention, a simulation fault value of the case that an estimated fault occurs is displayed on the screen and therefore diagnostic probability of true-or-false of displayed cause of the fault can be improved. Moreover, since an estimated fault, a simulation value of the case that an estimated fault progresses and a normal period simulation value of the case that no fault occurs are displayed on the same screen, a simulation value of the estimated fault and normal value can be compared for judgement and thereby diagnostic probability of true-or-false decision of the estimated fault can be improved. In addition, since an estimated fault, a simulation value due to the estimated fault and a simulation value of the case that a measure is taken for the estimated fault are displayed on the same screen, probability of true-or-false decision of the estimated fault can be improved by comparing these values.
