Abstract

PURPOSE:To obtain the correct working state of each information processor even in case an abnormal state occurs by receiving and storing the signals from the information processor. CONSTITUTION:An information history memory control circuit 5 receives the timing signal from an information processor 1 and sends the writing indication signal to an information history memory circuit 3. The circuit 3 receives the writing indication signal and then receives and stores the signal from an information processor 1. While the circuit 5 delivers the writing indication signal to a time history memory circuit 4 after receiving the timing signals by (n) times. The circuit 4 receives the writing indication signal and then the time information from the processor 1 to store it.
