Abstract
PURPOSE: To obtain a diagnosis system which eliminates the need of diagnostic data and simplifies fault analysis, by providing a retrial control circuit which retries the operation of a diagnosed device, disgnostic control circuit which reads out the operation state, and a method which stores the operation state.
CONSTITUTION: When diagnosed device 1 generates an error during its operation, retrial control circuit 3 is actuated via error detection circuit 5 to give the instruction of the retrial of device 1. Diagnostic control circuit 2 collects the operation states of the retrials and counter 4 counts the number of retrials; and when circuit 3 starts the final retrial after the contents of counter 4 reaches the fixed number of times, FF11 is set via gate 10. Gate 9 stops clock signals and afterwards, circuit 2 supplies the signal to unit 1 clock by clock. Circuit 2 reads out operation states and stores them in memory circuit 8. By circuit 2, data stored in circuit 8 are sent out to simulator 6, simulation is performed on the basis of the data in the operation state, and its results are displayed on display unit 7 via buffer register 14, thereby making fault analysis.
