<p>PURPOSE:To easily decide the most important abnormal route and to attain the rapid and proper processing of a plant by deciding the most important alarm at the time of outputting a new alarm based upon the sort and generation order of the alarm and displaying the generation route so as to be emphasized as compared with other routes. CONSTITUTION:When various alarms are generated from an abnormality generating route identifying means 8 due to the abnormality of a plant, respective generation routes are identified, an abnormality generation order deciding means 11 is started, and whether the start of the means 11 is due to a pulse signal (a) generated from a pulse generator 5 or time sequence data from a generation order table 12 is decided. Then a most important alarm deciding means 15 is started, the degree of importance, i.e. 'weight' X 'generation order', is calculated from the values of weight and generation order of the downstream alarm in a time sequence data table 13 and an abnormality generation route color display driving means 16 is started in accordance with the most important alarm out of respective alarms. At that time, the abnormality generating route is displayed by red e.g. on the display means 3 so as to be remarkably observed as compared with other routes and an alarm is simultaneously generated.</p> |
