PURPOSE:To read correct data from a correct value storage area, to automatically refer answer data, and to reduce manhour and the cost of a list by outputting a correct value read signal from a pseudo control part. CONSTITUTION:The correct value is read from the correct value storage area 14 by the correct value reading signal 18 included in control data consisting of control information, address information and data information, and the correct value is accumulated in register 8 in a reference circuit 7. Here, a tested circuit 17 returns a signal informing a pseudo controller 1 of the reception of control data, namely, the answer signal 19, and simultaneously returns answer data. Then, the reference circuit 7 refers correct value data accumulated in the register 8 and answer data by setting the answer signal 19 as a trigger. When they are correct, subsequent control data are sequentially executed. When they are dissident, an error is reported and a system is terminated. |
