Abstract

PURPOSE:To make it possible to make tests without influencing a circuit in progress of operation during the extension of a circuit, by transmitting set contents of a register through the operation of a maintenance board on an ON-line data communication system. CONSTITUTION:During the ON-line operation, a circuit address and test data equivalent to an extension circuit are set to the maintenance board and then, depressing the data set key on the maintenance board stores the set circuit address in circuit holding register 19 and test data in data holding register 21. Then, if the address signal from the circuit controller agrees with the content set to register 19, the output of circuit-address comparative coincidence circuit 20 becomes ''ON'', normal data from the circuit controller is inhibited by inverter 22, and the test data preset to register 21 is transmitted to circuit-interface correspondence circuit 10 via change-over circuit 15 and distributor circuit 17.
