Abstract

PURPOSE:To improve the debugging efficiency of displaying software by simulately changing the state of an apparatus for the CRT display software by using the specification information of the apparatus and updating display data in a plant monitoring system. CONSTITUTION:In a debugging mode, a plant state forming processing part 7 inhibits the data writing in a plant state table 4 and the data are written in the table 4 by a CRT display debugging processing part 6 instead of the part 7. The name and display format of an apparatus to be displayed on a CRT are defined in display specification information 3. A CRT display processing part 2 edits the state of the apparatus from the table 4 in accordance with the name of the apparatus for the information 3 and displays the edited result on a CRT display/input device 5. At the time of debugging, the debugging processing part 6 is interrupted by an instruction from the device 5 and each apparatus in the information 3 is read out in each interruption to change the state of the corresponding table 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a debugging method in a computer system, and more particularly to an efficient debugging method for software intended for screen display using a CRT.

[Conventional technology]

A common method for debugging a CRT display in a conventional computer system is to use a simulator 9 connected to a computer 1, as shown in FIG. 5(a). In an actual computer system, during debugging, the simulator 9 simulates the role of the instrumentation group that captures the plant status or the lower-level computer that processes the information of the instrumentation group in a distributed manner and transmits it to the upper level. The plant state creation process 7 creates a plant state table 4 that reflects the state of plant devices and equipment, such as closed state and pump operation/stop state, by changing the plant state table based on the input information of the simulator. A CRT display processing 2 debugs software based on the display on the CRT display input device 5. At this time, the debugger turns the simulator switch ON and ○FFL, checks whether the corresponding display is the same as the specification, and if it is the same, turns the next input switch 0N-OFF and checks again. It becomes work.

In addition, in Figure 5(b), without using a simulator, the CR
A debugging method that rewrites the plant status table by inputting device/equipment names and their status from T is also increasing. In the debug mode, the plant state creation process 7 is prevented from writing to the plant state table 4, and instead, the debug plant state creation process 10 is enabled to write. This debugging plant state creation process 10 is also performed by humans one by one, just like the simulator.
The name and status of each device must be entered, which takes a lot of effort. Note that Japanese Patent Publication No. 61-24733 is related to the debugging method.

[Problem to be solved by the invention]

The above-mentioned conventional technology is designed to create debug items and follow the test items for software that requires a large number of points to be checked, such as CRT display processing that displays the status of numerous devices and equipment for the purpose of displaying the status of a plant. There is a problem in that it takes a lot of time and amount of work to change the state of equipment and equipment by rewriting the plant state table using a simulator, which leads to omission of test items and affects the quality of the software itself. is giving.

In recent years, the task of creating software, including software for CRT display, has become easier, but the method of debugging software still requires the labor-intensive method described above, which reduces debugging time. is required to be shortened. Furthermore, as plant status display has shifted from graphic panels and the like to CRT displays, the number of software requiring a large number of debugs as described above is increasing.

An object of the present invention is to reduce the time and number of steps required when debugging CRT display software.

[Means to solve the problem]

In order to achieve the above purpose, the state of devices and equipment was manually set according to the test plan during debugging, but the state of devices and devices defined using display specification information already defined in the computer To operate a CRT display debugging process that sequentially changes the state of a device in a simulated manner during debugging.

At this time, since the CRT display debugging process rewrites the status table of the device/equipment as defined as one display specification, testing can be performed without creating test data and without manually inputting test data.

As described above, the present debugging method makes it possible to reduce the time and number of steps when debugging software for CRT display processing.

[Effect]

CRT display debug processing uses information predefined for display, such as device/equipment names and display formats of display specification information for CRT display, and uses plant information that stores the status of each device/equipment. Rewrite the state of the state table in a simulated manner. Thereby, debugging is possible by comparing the results displayed by the CRT display processing to be debugged with the specifications. By repeating this process, testing can be easily performed without the hassle of manually inputting test data.

〔Example〕

An embodiment of the present invention will be shown below.

The CRT display debugging process 6 shown in FIG. The status of each device is stored. In FIG. 1, in the normal online mode, the plant state creation process 7 stores the state of the lower-level computer or the calculation group 8 in the corresponding area of the plant state table 4 as the state of each device/equipment. In the debug mode, the plant state creation process 7 does not write to the plant state table 4, but instead writes in the CRT display debug process 6.

The display specification information 3 defines the name of the device/equipment to be displayed on the CRT, and also defines the display format thereof. The CRT display processing 2 edits the status from the plant status table 4 according to the name of the device/equipment in the display specification information 3, and displays it on the CRT display/input device 5. At this time, during debugging, an instruction from the CRT display/input device 5 causes an interrupt to the CRT display debugging process, and the devices/equipment in the display specification information 3 are read one by one for each interrupt, and the corresponding plant status table is created. change the state.

FIG. 2 shows CRT debugging processing. Each time an interrupt occurs from an input/output device, the device/output device is
Refer to the equipment definition (101) and change the plant status table 4 corresponding to the device/equipment (102). Then, the changed test target device/equipment name and its status are displayed (102).

FIG. 3 shows a specific example of display by CRT display processing 2. The one surrounded by a dotted line at the bottom right is the display indicating that the CRT display debugging process has processed valve A as closed, and the other displays are the software CR to be debugged.
The display is performed using T display processing 2.

Figure 4 shows the display specification information for device/equipment names A and B.
, C... and others are defined in order. This definition order is
Since it corresponds to the CRT display specifications, first, when the plant status table 4 of the valve A of the device/equipment is rewritten by an interrupt to the CRT display debugging process 6 from the first CRT display/input device 5, the CRT Display processing 2 changes the display of valve A to A in Figure 3 according to the display specification information in Figure 4.
Do it in the position. At this time, the status of A is displayed at the bottom right of the screen by the CRT display debugging process 6, so by comparing these with the specifications, the display position, symbol, display device name, etc. can be confirmed. If you want to debug the next device/equipment B, use the CRT display device shown in Figure 1.
It is sufficient to insert an interrupt from the RT display device/input device 5 to request processing of the next device/at device. This can be done by assigning a spare key on an input device such as a keyboard to this interrupt. 1 in Figure 2 for each interrupt.
When referencing display specification information 3 with 01, set the reference data to 1.
If you update them one by one, you will be able to continue debugging.

Interrupts to the CRT display debugging process 6 can also be generated at regular intervals using a timer inside the computer. At this time, there is no need for manual input, so efficiency can be further improved.

〔Effect of the invention〕

According to the present invention, in a test of CRT display processing, the display position of the device/equipment and definition mistakes in the data definition table are also displayed on the CRT.
By comparing the equipment, its status, symbols on the CRT, and specifications, debugging can be easily performed without creating debugging data, and it is also easy to reproduce debugging that has been performed several times. This has the effect of increasing debugging efficiency.
