PURPOSE:To enable to quickly judge failures of slave electronic computers individually from the main electronic computer, by providing registers which periodically registrate the operating condition corresponding to slave electronic computers. CONSTITUTION:The main electronic computer MC and slave computers M1-Mn are connected with data buses DB1, DB2 via an interface control circuit IF. IF is provided with registers R1-Rn corresponding to M1-Mn and the operating status of M1-Mn is periodically and individually registrated. The registers R1-Rn are periodically set, the read-in operation by MC is periodically made, and while M1-n are normal, the registers R1-Mn repeat set/reset. If any failure is present, the corresponding register is reset for the discrimination of failure, allowing to individually monitor a number of slave electronic computers. |
