14) stores a plurality of diagnostic routines divided into each test unit. (15) is a diagnostic routine execution area, which calls one of the diagnostic routines stored in the diagnostic routine storage area (14) and executes device diagnosis using the diagnostic routine.

Fig. 5 (A) is a diagram showing the diagnostic routine divided into each test unit stored in the diagnostic routine storage area (14), and Fig. 5 (B) is a diagram showing the diagnostic routine divided into each test unit stored in the diagnostic routine storage area (14). This is a diagram showing an execution routine for each test, in which (15a) indicates a control information area for storing control information for each test, and (15b) indicates a diagnostic program area.

Next, the operation will be explained. As shown in Fig. 3, the CPU (
8) is connected via the 232C interface (4), and when the device is powered on and the operator interacts with the diagnostic support bag W (1), the c
p U (8) is driven, an initial program is read from ROM (5), and IPL is performed. IP
When L is performed and the device becomes operational, the input/output control device (2) loads the FDD device into the control memory (6)! The program necessary for diagnosis stored in (7a) is transferred to the diagnostic support device (1).
reads the programs necessary for diagnosis from the FDD device (7b) into a built-in main memory (not shown) and moves to execution of the diagnosis programs.

When the execution of the diagnostic program is started, control is transferred to the diagnostic monitor (13) shown in FIG.
After executing a predetermined protocol with the diagnostic support device (1), the device is connected to the diagnostic support device (1).

Here, the operator operates the diagnosis support device (1) and inputs the addresses of the devices to be diagnosed (e.g. device 1 (11) and device 2 (12) shown in FIG. 4) and the diagnostic routine number (e.g. By inputting routine A and routine B) shown in FIG. 10 in an interactive manner, these data are output to the diagnostic monitor (13), and the diagnostic monitor (13) executes the diagnostic routine for the device at the corresponding address.

Here, the operator selects device 1 (11) and device 2.
A case will be explained in which the address of (12) is specified and routines A and B are executed routines.

First, the diagnostic monitor (13) calls routine A, which is an execution routine, from the diagnostic routine storage area 14), sets the address of device 1 (11) to be diagnosed in the control information area (15a) of routine A, and Transfer to the diagnostic routine execution area (15).

In the diagnostic routine execution area (15), device 1 (
The address of device 1 (11) is read and diagnostic routine A diagnoses device 1 (11). Device 1 (11
) is diagnosed and it is confirmed that it is operating normally, control returns to the diagnostic monitor (13), and the diagnostic monitor (13) checks whether there is a next execution routine for device 1 (11). be done. If diagnostic routine B exists as the next execution routine, call diagnostic routine B again from the diagnostic routine storage area (14), transfer it to the diagnostic routine execution area (15) in the same way, and transfer it to the diagnostic routine execution area (15). At step 15), device 1 (11) is diagnosed by the diagnostic routine. This diagnosis is completed,
When it is confirmed that device 1 (11) operates normally in both routine A and routine B, a status indicating that device 1 (11) has operated normally is set in the diagnostic routine execution area (15), and the diagnostic monitor Control is transferred to (13). The diagnostic monitor (13) reads the status set in the diagnostic routine execution area (15) and notifies the diagnostic support bag f(1) that the diagnosis of device 1 (11) has been completed.

When the diagnosis support device (1) receives a notification that the diagnosis of device 1 (1, 1> has been completed), it issues a command to the diagnosis monitor (13) to diagnose the next device 2 (12).
Routine A and routine B are executed for device 2 (12) in the same manner as described above, and the diagnosis of device 2 (12) is completed.

[Problems to be Solved by the Invention] In the conventional diagnostic device as described above, the diagnostic program is executed as described above and diagnoses multiple devices serially, so the number of connected devices is If the number increases, there is a problem that the diagnosis time becomes long. Conventionally, in order to perform diagnosis by automatically operating multiple devices in parallel at the same time (hereinafter referred to as parallel running), it has traditionally been necessary to use a host computer to perform large-scale diagnosis. equipment was required.

In addition, “
The automatic diagnosis method is configured so that the operator can check the configuration status of additional mechanisms and all peripheral devices, as well as the execution results of the diagnostic program, just by starting the diagnostic program for the first time. Although the load is reduced, the problem is that the device to be diagnosed and the routine to be diagnosed cannot be selected, and the operation of diagnosing multiple devices by running them in parallel is not performed, so the processing takes time. There was a point.

This invention was made to solve this problem, and allows multiple devices to be operated in parallel at the same time to perform diagnosis without requiring large-scale equipment such as a host computer. The purpose is to obtain a diagnostic device that can be shortened.

[Means for Solving the Problems] A diagnostic device according to the present invention provides a routine control information area in a memory area in an input/output control device, and stores the device address of the input/output device that is being diagnosed and the device that is being diagnosed. Information on whether to disconnect from the target device and routine information indicating whether to continue executing the routine being executed for the device, execute the next routine, or execute diagnosis for the next device are stored, and each It was decided to update the memory contents by executing the routine and notify the diagnostic support device.

[The information in the action coroutine control information area is read by the diagnostic support device via the diagnostic monitor, and the diagnostic support device performs parallel processing of multiple devices by giving the diagnostic monitor the routine to be executed next or the device to be diagnosed next. Running becomes possible.

[(18) is the routine information bit, "00" is the routine continuation (18a), rOl" is the execution of the next routine (1
8b), '10J means the next device (18c). Further, (19>) is a device address bit.

The operation will be explained below. Operations other than writing and reading the routine control information area (16) are the same in FIG. 1 and FIG. 4. The operator selects Device 1 (11) and Device 2 (1) as the devices to be diagnosed.
2) is specified and input is input to the diagnostic support device (1) to execute diagnosis of routine A and routine B for both devices (11) and (12).

The diagnostic support device (1) notifies the diagnostic monitor (13) of the input information, and the diagnostic monitor (13) calls routine A, which is an execution routine, from the diagnostic routine storage area (14) and displays the routine A's control information area. The address of device 1 (11) to be diagnosed is set in (15a) and transferred to the diagnostic routine execution area (15).

When routine A is executed and device 1 (11) is activated, bit ■ in the routine control information area (16) is set to "1" and r□ is set in bit IV (19) under the control of routine A. set, the diagnostic monitor (1
Control returns to 3).

The contents of the routine control information area (16) are “0100J
However, this means that the device currently being diagnosed is device 1.
(11) means that the currently executing routine A is left as it is and moves to the next device. The diagnostic monitor (13) transfers the contents of the routine control information area (16) to the diagnostic support device (1).

The next device for the diagnostic support device (1) is device 2 (12).
) to the diagnostic monitor (13).

In this way, routine A is executed for device 2 (12), device 2 (12) is activated, and device 1 (11) and device 2 (12) enter parallel running.

During this parallel running, when information such as READY IT is returned from device 1 (11), r
ooloJ is set. This means that the next routine, routine B, is executed for the device 1 (11) currently being diagnosed. The diagnostic support device (1) sets routine B in the diagnostic routine execution area (15) via the diagnostic monitor (13) and executes the diagnosis using the next routine.

If information such as READY IT is returned from device 2 (12), the routine control information area (
16) is set to roool, +, which means that the next routine, routine B, is executed for device 2 (12), and the diagnostic support device (1) is configured to perform the same routine as for device 1 (11). Similar processing is performed.

If the process ends abnormally, bit I (17) is set to "1", and the diagnosis support device (1) disconnects the device and ends the diagnosis.

In the above embodiment, since there are two devices, one bit is sufficient for bit IV (19), but if there are three or more devices, the number of bits will be determined according to the number of devices.
