PURPOSE:To improve the reliability of backup by making a backup system dual in a distributed computer system. CONSTITUTION:Computers 21-2n fetch input signals 11-1n and output control signals 61-6n. Stand-by computers 100 and 101 for backup take in input signals 11-1n and output control signals 108 and 109. A monitor circuit 102 generates self-diagnostic signals 104 and 105 if a trouble occurs in the self-diagnosis of computers 100 and 101. The monitor circuit 102 takes in self-diagnosis signals 104 and 105 of computers 100 and 101 and sends switching signals 71-7n to switches 41-4n. |
