DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an error message display device applied to a data file check device for displaying a graphic screen to be displayed on a display device, and more particularly to a data display device for displaying a graphic screen. The present invention relates to an error message display device for quickly creating a file.

[0002]

2. Description of the Related Art Conventionally, there has been a distributed control system for controlling and monitoring a plant by using a CRT display device. In such a distributed control system, the CRT display device performs various graphic displays such as a plant diagram showing the configuration of the entire plant to be controlled.

[0003] Such a graphic screen is created on a target machine that displays the graphic screen, or a data file is created by a graphic editor function of a personal computer or the like. When a data file of a graphic screen is created by a personal computer or the like, it is required that error detection and correction of the data file can be performed quickly.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and in a data file check device for displaying a graphic screen, when an error in a data file is detected, An object of the present invention is to provide an error message display device capable of accurately grasping an error location and correcting the error promptly.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a device for checking a data file for displaying a graphic screen to be displayed on a display device, and displays a graphic screen based on the data file. A first display unit for displaying, when an error is detected as a result of checking the contents of the data file, a second display unit for displaying a message related to the error on a pull-down menu for each error; A third display unit that receives a signal output by pointing the error message displayed by the display unit by the pointing device, and highlights a corresponding portion on the graphic screen corresponding to the error message. An error message display device characterized in that:

[0006]

The data file check function is used, for example, when converting a data file created by a personal computer into a source file for a target machine.
It checks whether there is an error in the contents defined there. When an error is detected, an error list file is created with a message containing the error content,
The second display means displays this error list on a pull-down menu.

When a specific message on the pull-down menu is designated, the third display means highlights a corresponding graphic portion on the graphic screen corresponding to the designated error message. As a result, from the confirmation of the error message displayed due to the occurrence of the error, the corresponding portion on the corresponding graphic screen can be accurately grasped, and various figures can be easily corrected.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a configuration block diagram showing one embodiment of the present invention. In the figure, 1 is a display device such as a CRT,
Reference numeral 2 denotes a pointing device such as a keyboard and a mouse. Reference numeral 3 denotes a block generally showing a CPU, which is connected to the CRT display device 1 and the pointing device 2.

In the CPU 3, reference numeral 30 denotes an editor for creating a graphic screen, 31 denotes a data file created by the editor 30, and 32 denotes a data file according to a predetermined definition. It is a checking means to check whether there is, and also functions as a converter to the source file. 33 is a source data file of the target machine created when no error is detected as a result of the check by the check means 32, and 34 is an error created when an error is detected as a result of the check by the check means 32 Indicates a list file.

Reference numeral 41 denotes first display means for displaying a graphic screen based on the data file 31, and reference numeral 42 denotes a second display for displaying a message related to the error based on the contents of the error list file 34 on a pull-down menu for each error. Means 43 for receiving a signal output by indicating the error message displayed by the second display means 42 with the pointing device 2, and for highlighting a corresponding portion on the graphic screen corresponding to the error message. Is a third display means.

The operation of the apparatus having the above configuration will be described below. FIG. 2 is a flowchart showing the operation of the conversion process (conversion process) from the data file to the source file of the target machine. In this flowchart, the checking means 32 checks whether or not the contents of the data file 31 are created according to a predetermined definition (steps 1 and 2). As a result, when an error is detected, information such as an error content, a primitive name, and a graphic ID number are sequentially stored in the error list file 34. If no error is detected, a message indicating a normal end is stored in the error list file 34 (steps 3 and 4).

Next, the second display means 42 converts the error list file 34 into a pull-down menu definition file and displays it on the display device 1 (step 6). FIG. 3 is a flowchart showing the details of the message reference operation in step 6 in FIG. Here, first, an error message pull-down menu definition file is loaded, and the message is displayed in a pull-down menu (MENU) (steps 61 and 6).
2) Then, it is in a state of waiting for key input (step 6).
3).

FIG. 4 is a diagram showing an example of an error message displayed on the pull-down menu (MENU) on the display device 1 in this state. Here, it is indicated that an error has been detected in the attributes of the three figures, and the figure ID number specifying the figure is displayed in the last part of each message, for example, as "875". Then, in this graphic ID number “875”, “Invalid
nge max. Ormin "informs that there is an error in the maximum or minimum range setting data.

On the display screen, a graphic screen based on the data file 31 (here, a plant diagram of the pulp control system) is displayed, and in this screen, a pull-down menu (MENU) is displayed in a window format. Referring back to FIG. 3, the figure ID number (for example, “8
75 ") using the pointing device 2 (step 64), the third display means sets the corresponding figure in the graphic screen, in this case, the figure indicating the central digester, to high. Light display is performed (step 65).

[0015] Thus, the operator can immediately find the error graphic on the graphic screen created by him, and can shift to the work of correcting the graphic. In step 64, when the return key is pressed,
The command input pull-down menu definition file is loaded and the process ends (step 67). For the shift to the graphic correction work, for example, a graphic attribute edit command is called on the screen where the highlight is displayed in step 65, and the relevant graphic (the graphic highlighted) is selected. Then, an editing screen is displayed so that necessary data can be corrected there.

FIG. 5 is a diagram showing an example of the editing screen. Here, in the example of the correction screen of the graphic ID number “875”, the setting data of the maximum range is “0” and the setting data of the minimum range is “100”, and the minimum range that should be smaller than the maximum range Is an error because it is larger than the maximum range, and the data in this portion will be corrected respectively.

In this embodiment, the display of the error message in the pull-down menu is displayed as a window. However, the display may be performed by expanding the screen.

[0018]

As described above in detail, according to the present invention, it is possible to accurately grasp the relevant graphic location on the corresponding graphic screen from the confirmation of the error message displayed due to the occurrence of the error. An error message display device capable of quickly detecting and correcting an error in a data file can be realized.
