[Industrial application field]

The present invention relates to a method for diagnosing a peripheral device control program for diagnosing a control program executed by a peripheral device connected to a data processing device.

[Conventional technology]

In order to diagnose whether there is a fault in the control program executed by a peripheral device connected to a data processing device, conventionally, a series of test programs consisting of multiple commands are issued from the data processing device to the peripheral device. In addition to configuring the command to
It was configured so that it would be bused to the next test.

When it is necessary to obtain more detailed failure information at the error location, the operator creates a detailed test program for that purpose using a simple language and executes the created detailed test program for the two peripheral devices. By doing so, the necessary fault information could be obtained.

[Problem to be solved by the invention]

However, with such conventional technology, there is a problem in that the command execution procedure leading up to the occurrence of the failure becomes unclear. Therefore, the conditions for the occurrence of the failure cannot be easily reproduced.
The drawback is that it takes too much time to analyze failures in peripheral device control programs.

The present invention has been made in view of the above circumstances, and is a peripheral device control program that makes it possible to easily perform failure analysis of a control program by easily reproducing the conditions for the occurrence of a failure. The purpose is to provide a diagnostic method for

The diagnostic information storage means 12 stores the diagnostic information in correspondence with the diagnostic information storage means 12.

Therefore, according to the present invention, since the command execution procedure leading up to the occurrence of a failure is recorded, the conditions under which the failure occurs can be easily reproduced. This makes analysis easier.

〔Example〕

Hereinafter, the present invention will be explained in detail according to examples.

FIG. 2 shows a system configuration diagram for realizing a diagnostic method for a peripheral device control program according to the present invention. As shown in this figure, one aspect of the present invention includes a data processing device main body 1a and a floppy disk device 3a.

A data processing device consisting of a hard disk device 3b, a display device 4, and a keyboard 5 is connected as four peripheral devices, and is configured to diagnose fault information of a control program executed by a device under test 2a. .

An operator who wishes to diagnose the control program of the device under test 2a by issuing commands to the device under test 2a must first set the order of the two commands to be issued as shown in FIG. 3(A). become. For example, when the device under test 2a is an image scanner, the first command issued is a paper size selection command, the second command is a CCD image sensor reading execution command, and the third command is an automatic feed command. This will be defined as a paper execution command.

Setting the order of commands to issue in this way:
Next, the operator creates a command sequence execution program and stores it in the floppy disk device 3a in order to issue commands in accordance with this issuing order. This command sequence execution program is shown in Figure 3 (
As shown in B), set the command as a parameter to “EX
Executable statement for reading the “DV” instruction and this “EXDV”
The basic unit is an executable statement that is paired with an executable statement that instructs to display either a normal message or an abnormal message according to the analysis result obtained by executing the command,
It will be programmed.

In the example of Figure 3 (B), on line 5, number 1o, the EXDV command is executed one after another with command A as a parameter, and on line 2, number 2
0 instructs to display a message for the execution of this line number 10,
Next, on line number 30, use command B as a parameter and EX
The program reads the DV command and instructs to display a message for the execution of line number 30 at line number 40, and so on.

Next, with reference to FIG. 4, the routine processing of the EXDV instruction executed by the CPU included in the data processing device main body 1a will be described. Here, FIG. 4 shows an example in which the EXDV command is executed using command A as a parameter.

First, the CPU sends the data needed to execute the command as shown in step 1. When this data setting is completed, in the subsequent step 2, a command is issued to the device under test 2a. Then, in the next step 3, response data returned from the control program of the device under test 2a that executes the command issued in this manner is received and stored. In the subsequent step 4, this stored data is analyzed to see if there are any errors, and in step 5, it is determined that there is no error.

Proceed to step 6 and set the error flag off.

On the other hand, if it is determined in step 5 that there is an error, the process proceeds to step 7 and the error flag is set on. in this way.

The EXDV command issues a set command to the device under test 2a, and processes the response data returned from the device under test 2a in response to the issuance of this command to be analyzed.

Since the EXDV command executes such a routine process, when the operator requests the startup of a command sequence execution program created in advance, the CPU of the data processing device main body 1a starts running.

Commands are issued in accordance with the order of the executable statements of this command sequence execution program, and failure information of the control program is analyzed. and.

The CPU processes the control program failure information obtained in this manner so as to be stored on the hard disk device 3b in association with the command issuance order, as shown in FIG.

In this way, failure information of the control program of the three devices under test 2a is recorded.

In the present invention, unlike conventional methods, it is possible to always clarify the command execution procedure leading up to the occurrence of a failure.

Although the illustrated embodiments have been described above, the present invention is not limited to these embodiments. for example.

The location where the failure information is stored is not limited to the hard disk drive, but may also be a floppy disk drive or, if the amount of data is not that large, the data processing device itself.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to easily reproduce the conditions for the occurrence of a failure in one peripheral device control program, so that failure analysis of nine peripheral device control programs can be easily performed.
