Description

  The present invention relates to a screen creation device that creates a screen to be displayed on a display device that displays a user-created screen such as a programmable display, and more specifically, screen creation that allows a part of the screen to be drawn in detail. It relates to the device.

  Conventionally, for example, a programmable display is widely used as an HMI (Human Machine Interface) of a control system. A display device, such as a programmable display, communicates with a programmable logic controller (PLC) that controls the device to display / control the state of the device. The operation for displaying the device state on the screen and the operation for controlling the device state in accordance with the operation are displayed on a previously created screen. Such a screen is created by a computer in which screen creation software (drawing software) is installed and downloaded to a programmable display.

  With the recent increase in display size of display devices, the size of the screen to be displayed has also increased, so that the entire large-scale system can be displayed sufficiently. For example, the overall configuration of the plant can secure a screen size that can be displayed including a detailed portion on one screen. As the screen capacity has increased in this way, there are an increasing number of users who draw detailed images on one screen. A lot of piping is drawn on the plant configuration screen, but for the purpose of monitoring as if looking at the actual plant, piping and other equipment are drawn in a form closer to the actual configuration. It is hoped that.

A technique capable of drawing a screen in detail is disclosed in Patent Document 1, for example. This document describes that a main screen for drawing work, a sub-screen showing a reduced view of the whole view, and a reference screen for displaying a figure to be zoomed are displayed at the same time. Accordingly, the drawing work can be advanced while confirming the result of the drawing work performed on the main screen with the enlarged graphic displayed on the reference screen.
JP-A-5-61958 (published March 12, 1993)

  However, in the method described in Patent Document 1, it is not possible to directly perform drawing work on the enlarged figure on the reference screen. Therefore, the drawing work must be performed on the main screen while referring to the enlarged figure on the reference screen. Don't be. In order to draw a detailed part, it is desirable that the drawing work can be performed directly on the figure on the reference screen. In addition, in order to check how the drawing work is reflected in the entire image, the sub-screen is referred to, so that the drawing work is troublesome while viewing the three screens.

  The present invention has been made in view of the above-described problems, and an object thereof is to make it possible to draw a detailed portion of a screen more easily.

  A screen creation device according to the present invention is a screen creation device that creates a screen to be displayed on a display device, and in order to solve the above problems, a designated area of the displayed main screen is enlarged and the main screen is expanded. Comprises an enlarged display means for displaying as another partial enlarged screen, and a drawing operation common means for performing the same drawing operation on the main screen as the drawing operation performed on the partial enlarged screen. It is characterized by.

  In the above configuration, when the user designates a desired area on the main screen, the area is enlarged by the enlarged display means. When the user performs a drawing operation on the partial enlargement screen, the same drawing operation as the drawing operation is also performed on the main screen by the drawing operation sharing means. Thereby, the drawing operation on the partial enlarged screen is reflected on the main screen, so that the user can check how the drawing operation on the partial enlarged screen is reflected on the main screen on the main screen. Therefore, it is possible to easily perform a detailed drawing operation on the main screen.

  The screen creation device preferably includes a storage unit that stores the partial enlarged screen in a storage unit so that the partial enlarged screen can be reused in the storage device. As a result, the partially enlarged screen can be reused. Therefore, if a portion that is frequently edited on the main screen is registered, an operation for designating an area on the main screen for enlargement can be omitted.

  The screen creation program of the present invention is a program for operating any one of the screen creation devices, and causes a computer to function as each means. The screen creation program is provided by being recorded on a computer-readable recording medium. Thereby, it is possible to easily perform a drawing operation of a detailed portion on the main screen.

  The screen creation apparatus according to the present invention is performed on an enlarged display means for enlarging a specified area of a displayed main screen and displaying it as a partial enlarged screen different from the main screen, and the partial enlarged screen. A drawing operation common means for performing the same drawing operation as the drawing operation on the main screen is also provided. As a result, it is possible to confirm on the main screen how the drawing operation on the partial enlarged screen is reflected on the main screen, so that the detailed drawing operation on the main screen is facilitated.

  The user performs a drawing operation on the partial enlargement screen 302 using the drawing function of the drawing editor unit 13 in the enlargement window 203. At this time, the enlarged window 203 is in an active state where input is possible, and the drawing window 202 is in an inactive state where input is not possible. That is, either the drawing window 202 or the enlargement window 203 is in an active state.

  The drawing operation performed by the user on the enlargement window 203 is reflected on the area surrounded by the selection frame F1 on the main screen 301 displayed on the drawing window 202 by the operation processing unit 13b. Accordingly, the user can check the result of the drawing work reflected on the main screen 301 on the drawing window 201 while performing the drawing work on the partial enlargement screen 302 of the enlargement window 203. Therefore, the detailed drawing work can be performed using the enlargement window 203 while the partial enlargement screen 302 and the main screen 301 can be adjusted using the drawing window 202. Further, a detailed drawing operation performed on the partial enlarged screen 302 can be reflected on the main screen 301. Therefore, detailed drawing work can be performed more efficiently.

  When the drawing operation on the enlargement window 203 is completed and the user performs an operation of closing the enlargement window 203, the enlargement display unit 13a closes the enlargement window 203. When the user performs an operation to save the main screen 301 displayed in the drawing window 202, the data of the main screen 301 read to the work memory 11a is updated to the edited data, and the data storage unit 14 is stored as screen data. Therefore, this screen data is a drawing operation for the area specified by the selection frame F1.

  As shown in FIG. 3, when the user selects the part registration mode with the drawing window 202 and the enlargement window 203 open, the registered part display area 204 is displayed on the right side of the drawing window 202 by the part registration unit 13c. Is displayed. In this state, when the user performs an operation of dragging and dropping the enlargement window 203 to the registered part display area 204, the part enlargement screen 302 displayed in the enlargement window 203 is registered and registered by the part registration unit 13c. It is displayed in the component display area 204 as a reduced image.

  When registering the partial enlarged screen 302, the component registering unit 13c registers designation data indicating that the partial enlarged screen 302 is an area designated by the selection frame F1 together with the enlarged window 203. As the designation data, the coordinates of two diagonal points (for example, the upper left corner and the lower right corner) of the selection frame F1 are used.

  The registered partial enlarged screen 302 can be reused. Specifically, when the user drags and drops the reduced image of the partial enlarged screen 302 from the registered component display area 204 onto the drawing window 202, the portion registered in the component library by the component registration unit 13c. The enlarged screen 302 is read and displayed on the drawing window 201. At this time, the part registration unit 13c gives the specified data read together with the partial enlargement screen 302 to the operation processing unit 13b, so that the operation processing unit 13b expands the selection frame F1 by the read partial enlargement screen 302. Recognizing that it is a portion, the same drawing operation as the drawing operation on the partial enlargement screen 302 is performed on the area of the selection frame F1 of the main screen 301.

  In this way, by registering the partial enlargement screen 302 so that it can be reused, if the drawing operation is temporarily interrupted and terminated, if the partial enlargement screen 302 being edited is registered, the editing can be performed. When the work is resumed, the registered partial enlarged screen 302 can be read and displayed, and the editing work can be easily continued. If there is no registration function of the partial enlargement screen 302, when editing is resumed, it is possible to save the contents of the drawing performed on the area specified by the selection frame F1 by saving the main screen 301. Since the area itself designated by the frame F1 is not saved, it is not known which part was previously enlarged and edited, and the drawing operation cannot be continued for the same part.

  Also, by registering the partial enlarged screen 302 so that it can be reused, if a portion that is frequently changed or modified is registered as the partial enlarged screen 302, the work of designating an area in the selection frame F1 is omitted. be able to. In addition, it is possible to paste the partial enlarged screen 302 on which the latest drawing operation has been performed on the main screen 301.
