FIG. 8 is a part of a block diagram of an information processing system to which the present invention is applied. Referring to FIG. 8, the information processing system includes an input / output processing device 2 and an input / output device (hereinafter referred to as PI
The input / output channel 21 of the input / output processing device 2 and the PIO 1 are connected to each other.

FIG. 1 shows the configuration of a PIO 1 according to an embodiment of the present invention. Referring to FIG. 1, the PIO 1 is composed of a storage unit 11, a starting unit 12, an input / output unit 13, and a generation / comparison unit 14.

Now, in the information processing system of FIG.
Consider a case where IO1 is used and the input / output processing device 2 and the input / output channel 21 are tested and diagnosed.

When the test diagnostic command is executed, PIO1 is externally supplied.
Is instructed to store the operation regulation data. Upon receiving the notification of the operation regulation data storage instruction, the PIO 1 activates the storage unit 11. Referring to FIG. 2 showing the processing procedure of the storage means 11, the storage means 11 stores the operation regulation data sent from the input / output processing device 2 in the processing 111 and the processing 12 until the end notification from the input / output processing device 2. Keep remembering. When the end notification is issued to the PIO 1 from the input / output processing device 2, the storage unit 11 stores the number of the operation regulation data sent in the process 113. After storing the operation specification data,
In the processing 114, the storage means 11 activates the activation means 12 and ends the processing. The activation means 12 activated by the storage means 11 activates the input / output means 13 and ends the processing.

FIG. 3 shows a processing procedure of the input / output means 13.
Referring to FIG. 3, the input / output unit 13 activated by the activation unit 12 obtains the first operation regulation data from the storage unit 11 by the process 131. The input / output unit 13 that has obtained the operation regulation data creates control data to communicate with the input / output processing device 2 in process 132, and notifies the input / output processing device 2 of the control data. After notifying the input / output processing device 2 of the control data, the generation / comparison means 4 is activated in step 133 to wait for the end notification from the generation / comparison means 14.

After that, the input / output unit 13 that has received the end notification from the generation / comparison unit 14 obtains the next operation regulation data from the storage unit 11 in processing 134, and repeats the above operation. The input / output unit 13 which has processed all the operation regulation data,
The process ends.

The generation / comparison means 14 activated by the input / output means 13 of the PIO 4 will be described with reference to FIG. In FIG. 4, the generation / comparison means 14 activated by the input / output means 13 determines whether or not a read operation is performed in the process 141 in accordance with a read instruction or a write instruction operation command from the input / output means 13.

If the operation instruction from the input / output means 13 is a read operation, transfer data for the input / output processing device 2 is automatically created for the number of data instructed by the input / output means 13 in the process 142. Transfer data is sent to the input / output processing device 2. After the transfer data generation is completed or after the data transfer is completed, in step 143, the generation / comparison means 14 notifies the input / output means 13 of an end notification, and the processing is ended.

If the instruction from the input / output means 13 indicates a write operation in process 141, the transfer data sent from the input / output processing device 2 is automatically compared in process 144.

After the transfer data end notification sent from the input / output processing device 2, the generation / comparison means 14 notifies the input / output means 13 of the end notification in step 143 and ends the processing.

After completion of the input / output processing of all the input / output processing devices 2 and PIO 1, the input / output processing device 2 and the input / output channel 21 are input / output by comparing the input / output expected value data with the input / output result value data. You can confirm the normality of the operation.

Next, another embodiment of the present invention will be described with reference to the drawings.

FIG. 5 shows the configuration of a PIO 1 according to another embodiment of the present invention. Referring to FIG. 5, it can be seen that the pseudo obstacle means 15 is added to FIG.

The functions of the storage means 11, the activation means 12 and the generation / comparison means 14 are the same as those in FIG.

Referring to FIG. 5, the input / output unit 16 activated by the activation unit 12 obtains the first operation regulation data from the storage unit 11 by the process 161. The input / output unit 16 which has obtained the operation regulation data analyzes in process 162 whether or not there is a pseudo fault occurrence designation in the operation regulation data. here,
When the pseudo failure occurrence is designated, the input / output unit 16 activates the pseudo failure unit 15 and continues the processing. In the process 162, when the pseudo fault occurrence is not specified in the operation regulation data, the following process is executed.

Next, in process 163, the input / output means 16
Control data to be communicated to the input / output processing device 2 is created, and the control data is notified to the input / output processing device 2. After notifying the input / output processing device of the control data, the input / output unit 16 activates the generation / comparison unit 14 in process 163, and the generation / comparison unit 1
Wait for the end notification from 4.

After that, the input / output unit 13, which has received the end notification from the generation / comparison unit 14, obtains the next operation regulation data from the storage unit 11 in the process 135, and repeats the above operation. The input / output unit 16 which has processed all the operation regulation data,
The process ends.

The improper means 15 activated by the in / out means 16 in the PIO 4 will be described with reference to FIG. Figure 7
Then, the pseudo obstacle means 15 activated by the judging means 16 analyzes the notification data notified from the input / output means 16 in the processing 151. Here, the pseudo obstacle means 15 recognizes the pseudo obstacle type. After that, in process 152, the pseudo obstacle unit 15 causes the pseudo obstacle specified by the input / output unit 16 to end the process.

After completion of the input / output processing of all the input / output processing devices 2 and the PIO 1, the input / output processing device 2 and the input / output channel 21 are input / output by comparing the input / output expected value data with the input / output result value data. It is possible to confirm the normality at the time of operation failure.
