A feasibility study on the automated fault diagnosis system based on the signed diagraph was performed with the use of a practical pilot plant. The pilot plant was composed of two reactors and the peripheral equipment where 14 different state variables, such as flow rates and temperatures, were monitored and another 8 state variables, chiefly pressures, were measurable as off-line information. The diagnosis was carried out with the pattern of abnormality appearing in the on-line and off-line information of the state variables. The program was implemented on a microcomputer of an ordinary size.
