Abstract

PURPOSE: To prevent the discontinuation of the information in the occurrence of the fault and thus to enhance the reliability of the system, by using the system which is excluded from the constant connection with the external apparatus as the queuing system in order to secure a constant idling action.
CONSTITUTION: Each data of logic parts L1WL3 is given the majority through majority circuits ML1WML3 and then supplied to interface registers IR1WIR3 of each system. The data supplied to IR1 is given interface with external apparatus W1 via interface control part IC1 and through interface switch part IX, and similarly the data supplied to IR2 is given interface with apparatus W2 through IC2 and IX. However, the data supplied to IR3 has no corresponding external apparatus and accordingly receives the interface signals of other two systems at IX as shown by the dotted lines, and actuate IR3 and interface control part IC3 like other two systems in order to secure a usable state at all times (idling active state). Thus, an independent action becomes possible for each register and the control part.
