PURPOSE:To analyze a fault at accident effectively by storing the data at acci dent and delivering a series of data stored by a tracing request of an operator to a printer and a monitor panel at the same interval as that of the accident mode. CONSTITUTION:A control computer 10 consists of a central arithmetic unit CPU 11, a process input/output device 12 and a main memory 13. The information given from a process 14 is supplied via the device 12 to undergo the arithmetic processing through the CPU 11 and stored in the memory 13. A monitor panel 15 serving as a display device displays the state of each device, and these states are recorded by a printer 16. When the process 14 has a fault, etc., the CPU 11 decides a state change or a fault of a device. If a fault is decided, the analog quantity of the process 14 is calculated immediately after occurrence of the fault together with the time passed after occurrence of the fault. These calculated analog quantity and time are stored in the memory 13. If an operator requests the regeneration of the accident through an operating panel 17, said stored analog quantity is displayed successively in the same time chart as that used in the fault generation mode. |
