Abstract

PURPOSE: To ensure an automatic restarting of the system and thus to enhance the reliability of the system by delivering the recovery signals to the remote unit at the fault recovery time in the calculator system.
CONSTITUTION: In case the recovery signals do not reach central process unit 200 when terminal unit 100 is recovered from the fault, the fault is decided to be at the communication circuit or unit 200. And thus the time supervisory is given to the reply of the side of unit 100. In this case, the interruption is given from time supervisory mechanism 117 to control part 118, and the recovery signals are transmitted continuously through part 118 after a fixed time. When either unit 200 or the communication circuit is recovered, unit 100 receives the reply to the recovery signal and starts the restart process. The exactly same operation is given also in case unit is recovered from the fault. And this is also possible between the central process units.
