PURPOSE:To perform the automatic repair with no hand in case a logical device by using a variable logical circuit package, a fault detecting means, a transfer control means and a control logical data store device. CONSTITUTION:Either one of electronic circuit packages 1-1-1-n has a fault, a fault detecting circuit 4 detects this fault and separates the faulty package from a bus circuit 5. At the same time, the circuit 4 sends an indication to a transfer control circuit 3 and then sends the desired data to a variable logical circuit package 2 via a control logical data store device 7. Thus the package 2 backs up the faulty electronic circuit package. |
