Abstract
PURPOSE: To detect the fault of a logical operation circuit in a simple constitution by storing previously fault detection information or fault kind-classified information in a memory and obtaining fault detection or fault kind-classified information for the logical operation circuit.
CONSTITUTION: Plural detection points 2a...2g are set in logical operation circuit 1, and memory 7 is provided which plural signals from detection points 2a...2g are inputted to and stores previously fault detection information or fault kind- classified information in an address position corresponding to the value of combination of signals defined as an abnormal state by combination of each signal. Then, the combination of plural signals from detection points of logical operation circuit 1 which is connected to memory 7 is used as an address signal of memory 7 to obtain fault detection information or fault kind-classified information for logical operation circuit 1. Thus, the fault of the logical operation circuit can be detected in a simple constitution.
