Abstract

PURPOSE:To accurately diagnose the abnormality of a state even if the performance of a plant has changed due to secular change by statistically analyzing process data which has been preserved in a process history data preservation part and providing a limiting value decision part. CONSTITUTION:A limiting value generation part 4 consists of a process history data preservation part 41 preserving process data of the past and the limiting value decision part 42 which statistically analyzes process data preserved in the process history data preservation part 41 and decides the limiting value. For preserving a large quantity of process history data, a process history data storage area 412 using an optical disk and the like are provided, for example, and an operator interactive part 424 which decides the limiting value through an operator interactive device 5 is provided as well. With preserving process data of the past and statistically analyzing process data being preserved, the abnormality of the state can accurately be diagnosed.
