Abstract

PURPOSE: To enable to achieve fine error massage instruction to various troubles at the terminal of input and output, and to reduce the load of CPU and to speed up the processing, by performing check through the provision of hardware.
CONSTITUTION: If a failure is taken place at one input and output terminal 1, error check signal is produced as the status information, it is detected with the error check detection circuit 5 of the channel section 2, is outputted to the error command delivery circuit 6, and error command is produced. Next, a series of code group produced 6 is interpreted 7 and the status information is returned to the circuit 6 from the error information storage area 8 at the memory unit 3 through the data line. Further, this status information is immediately outputted to the status information storage area 9 being separate area in the terminal 1 and the unit 3. Further, after a series of processing like this, the interrupt of the input and output terminal is made.
