Abstract

PURPOSE:To improve the processing performance of a central processing part by interrupting the central processing part when an excellency signal shows defection during a read of return data. CONSTITUTION:Information is sent to device 13 to be controlled via input-output interface part 12 by the output instruction of central processing part 11. On the basis of this information, device 13 to be controlled operates and sends an excellency signal regarding its operation result and return information to input-output part 12. Then, central processing part 11 counts the time until the excellency signal from device 13 to be controlled is sent back to input-output part 12 after the output instruction. When the excellency signal is not returned from device 13 to be controlled in a certain time, input-output part 12 discriminates defection and interrupts central processing part 11 via interruption line 21. Thus, an input instruction for the confirmation of the excellency signal from central processing part 11 can be omitted, so that the processing performance of central processing part 11 is improved.
