<p>PURPOSE:To clear up the cause of abnormality in a short time by summing up and analyzing abnormality occurrence information stored in an abnormality occurrence memory as designating a retriving period and a parameter, and displaying graphically that result. CONSTITUTION:When a CPU 2 detects the abnormality occurrence of process data, it alarm-displays the abnormality occurrence information consisting of the time of occurrence, an occurring tag, occurring equipment and abnormal contents on a CRT display device 3a, and besides, it writes it in the abnormality occurrence memory 9 of an auxiliary storage device 11. When an abnormality occrrence information analyzing command is inputted by keyboard 3b operation, the CPU 2 reads the abnormality occurrence information whose time of occurrence corresponds to the prescribed retrieving period out of the abnormality occurrence memory 9, and sums up each read out abnormality information as classifying it by every equipment. Further, it sums up the information as classifying it by every equipment and every kind of the abnormality, and edits it into format for summing up graphically each summed result. Then, the edited result is graphic-displayed on the CRT display device 3a.</p> |
