Screen layout information displayed on the monitor control screen 52, communication information for data acquisition, and the like are included in the screen definition data, and the monitor control system display device 1 processes the screen definition data. A monitoring control screen 52 is displayed on the display 3.
Since the monitor control screen 52 has many types and the number of sheets, a screen ID that can be uniquely identified is assigned to each screen, and the monitor control screen 52 can be switched by designating this screen ID.

FIG. 5 is a flowchart for explaining the overall processing when creating another window screen in the monitoring control system display device 1 according to the first embodiment.
Assume that the monitoring control system screen 50 shown in FIG. 4 is displayed on the display 3 as an initial state of this flowchart.
In the monitoring control system display device 1 according to the first embodiment, the monitoring control screen management unit 14 generates monitoring control screen data from the screen definition data held by the screen definition storage unit 17 and outputs the monitoring control screen data to the display unit 13. Thus, the monitoring control screen 52 is displayed on the display 3 for the operator.

First, the entire process will be described with reference to the flowchart of FIG.
In the block “waiting for input event” (ST1), the monitoring control screen management unit 14 waits for an event input from the input unit 12, and when the event is acquired, the process proceeds to the next block “input event determination” (ST2).

In the block “input event determination” (ST2), the monitoring control screen management unit 14 determines the content of the input event.
If the content of the event is a separate window start event, the process proceeds to the block “cutout range information acquisition process” (ST3). If the event content is another event, the process returns to the block “waiting for input event” (ST1).

In the block “cutout range information acquisition process” (ST3), the monitoring control screen management unit 14 outputs the position information input from the input unit 12 to the cutout range management unit 15 when a separate windowing start event is acquired. The cutout range management unit 15 determines a start point and an end point from the input position information, and creates cutout range information. Here, the cut-out range information is composed of a pair of upper left corner coordinates and lower right corner coordinates. The monitoring control screen management unit 14 outputs the acquired cutout range information to the screen definition processing unit 16. After this processing is completed, the process proceeds to “different window screen creation processing” (ST4) in block ST4.
Details of the block “cutout range information acquisition process” (ST3) will be described later with reference to FIG.

In the block “separate window screen creation process” (ST4), the screen definition processing unit 16 acquires the currently displayed screen definition data from the screen definition storage unit 17, and uses the extracted range information acquired from the extracted range management unit 15. Originally, screen definition data of a necessary range is extracted, and screen definition data for another window screen is generated. The screen definition processing unit 16 outputs the generated screen definition data to the monitoring control screen management unit 14. The monitoring control screen management unit 14 creates another window screen based on the screen definition data and outputs it to the display unit 13 . After the completion of this process, the process proceeds to block “display process” (ST5).
Details of the block “ separate window screen creation process” (ST4) will be described later with reference to FIG.

  In the block “display process” (ST5), the display unit 13 displays the plant data collected by the communication processing unit on the basis of the separate window screen acquired from the monitoring control screen management unit 14 and the generated screen definition data. To display.

Next, details of the block “cutout range information acquisition process” (ST3) will be described with reference to FIG.
In the block “start point information input wait” (ST31), since another windowing start event is received in the block “input event determination” (ST2), the position designation information from the input unit 12 is the monitoring control screen management unit 14 And output to the extraction range management unit 15. This position designation information is acquired as start point information, and the process proceeds to the block “start point information determination” (ST32).

In the block “start point information determination” (ST32), the validity of the start point information acquired by the cutout range management unit 15 is determined.
Specifically, it is determined whether or not the coordinates are within the monitoring control screen 52. If it is determined that the coordinates are valid, the process proceeds to the block “waiting for input of end point information” (ST33). If the coordinates are invalid, the process returns to the block “waiting for starting point information input” (ST31).

  In the block “end point information input waiting” (ST33), the cut-out range management unit 15 acquires the start point information, and therefore acquires the next position designation information as end point information, and the block “end point information determination” (ST34). )

In the block “end point information determination” (ST34), the legitimacy of the end point information acquired by the cutout range management unit 15 is determined. First, it is determined whether or not the coordinates are within the monitoring control screen 52, and then it is determined whether or not the coordinates are located at the lower right of the coordinates of the starting point information.
In the first embodiment, as an example, since the upper left corner coordinates are used as the start point and the lower right corner coordinates are used as the end point, the range to be displayed in another window is specified, and thus this determination method is used. If it is determined that the coordinates are valid, the process proceeds to the block “cutout range determination process” (ST35). If the coordinates are invalid, the process returns to the block “waiting for input of end point information” (ST33).

In the block “cutout range determination process” (ST35), the cutout range management unit 15 has acquired the start point information and end point information up to the block “end point information determination” (ST34). This is cut-out range information.
This cut-out range information is output to the screen definition processing unit 16 and the process is terminated.

Next, details of the block “separate window screen creation process” (ST4) will be described with reference to FIG.
In the block “acquisition of cutout range information” (ST41), the screen definition processing unit 16 acquires cutout range information from the cutout range management unit 15, and proceeds to the block “acquisition of screen definition data being displayed” (ST42).

  In the block “acquiring screen definition data being displayed” (ST42), the screen definition processing unit 16 acquires the screen ID of the monitoring control screen 52 displayed on the display 3 from the monitoring control screen management unit 14. The screen definition data corresponding to the screen ID is acquired from the screen definition storage unit 17, and the process proceeds to the block "Generate another window screen screen definition data" (ST43).

In the block “generate screen definition data for another window screen” (ST43), the screen definition processing unit 16 extracts the cut range information acquired from the cut range management unit 15 and the screen definition data and parts acquired from the screen definition storage unit 17. Screen definition data for displaying another window screen is generated based on the drawing information.
Here, the structure of the screen definition data is shown in FIG. The screen definition data includes the position information and communication setting information of the components drawn on the monitoring control screen, together with the screen ID and the screen size.
Here, while changing the screen size of the screen definition data, leaving only the parts that are included in the extraction range among the defined parts and deleting the information of other parts, the screen for another window screen Generate definition data.

Specific processing will be described based on the detailed flowchart of FIG.
In the block “acquire component drawing information” (ST431), the screen definition processing unit 16 first acquires the component drawing information stored by the screen definition storage unit 17, that is, the width and height information when drawing the component, The drawing range (position, width, and height) of the part is clarified together with the part position information included in the screen definition data.

  In the block “collation of drawing range and cutout information” (ST432), it is determined whether or not this drawing range and cutout range information match, and if even a part matches, it is left, and if it does not match at all, it is deleted. .

  In block “all component completion determination” (ST433), it is determined whether or not the processing has been performed for all components. If not completed, the process returns to block “parts drawing information acquisition” (ST431) to repeat drawing of all components. Acquisition of information and collation between drawing range and cutout range information are performed.

  In the block “create monitoring control screen” (ST434), the screen definition processing unit 16 generates screen definition data for another window screen, and outputs the generated screen definition data to the monitoring control screen management unit 14. The monitoring control screen management unit 14 creates a monitoring control screen to be displayed as a separate window screen from the screen definition data, outputs it to the display unit 13, and ends the processing.

As described above, when creating a separate window screen, the parts outside the specified range are deleted from the screen definition data dynamically, that is, online without interrupting the monitoring control screen display. By generating the screen definition data, it is possible to create another window screen in a form that suppresses unnecessary communication.
The monitoring control screen 52 created as a separate window screen is drawn from a screen definition different from the original screen, and issues a separate communication request independently. However, since the monitoring control screen management unit 14 aggregates requests for each component, a redundant request is not issued to the plant system side.
Here, when the original monitoring control screen is closed, the communication request from the original monitoring control screen is invalidated, and only the communication request of another window screen is valid, so that no extra communication occurs. In addition, when creating another window screen, it is possible to easily add processing for automatically closing the original monitoring control screen.

  Previously, the screen definition data for the separate window screen was not generated, and the screen display was performed using the same screen definition data as the original monitoring control screen, so parts that are not included in the display range of the separate window screen There was also communication.

The function and operation of the monitoring control system display device 1 according to the first embodiment have been described above. How the monitoring control system display device 1 is used will be described below.
Here, in a situation where the user of the monitoring control system display device 1, that is, the operator is monitoring the plant using the example of the monitoring control screen shown in FIG. An explanation will be given of the operation of the operator when he wants to make the
An outline of the operation is shown in the explanatory diagram of FIG.

First, when the operator depresses the separate window button 53, the mode is switched to the separate window creation mode. In this situation, the operator uses the pointing device 5 to specify a range to be cut out as another window screen. The broken line portion in FIG. 10 corresponds to the cutout range.
Specifically, the operator uses the pointing device 5 to designate the cutout range by selecting a rectangle from the upper left corner to the lower right corner.
Thereby, another window screen 54 is displayed. Even if the monitoring control screen 52 is switched to another monitoring control screen in this state, since the separate window screen 54 is still displayed, it is possible to continue monitoring the range to be noticed.

  In the first embodiment, in the description based on the detailed flowchart of FIG. 9, the component definition information, that is, the width and height information when the component is rendered is stored by the screen definition storage unit 17. The monitoring control screen management unit 14 may store the information, and the screen definition processing unit 16 may acquire the component drawing information from the monitoring control screen management unit 14.

  As described above, in the first embodiment, when creating another window screen, the screen definition data for another window screen is deleted from the screen definition data of the original monitoring control screen by removing parts outside the specified range. Thus, there is an effect that the visibility of the monitoring control screen can be improved and the communication amount can be reduced.

Embodiment 2. FIG.
A second embodiment of the present invention will be described with reference to the drawings.
In the first embodiment, the process of displaying a single separate window screen by pressing the separate window button 53 in FIG. 9 and specifying the range by the start point and the end point has been described. Thus, the present invention relates to a monitoring control system display device capable of creating a separate window screen, that is, performing a continuous separate window screen creation process.

FIG. 11 shows a flowchart for explaining the processing according to the monitoring control system display device of the second embodiment of the present invention.
Each step is not different from the flowchart of FIG. 5 except that the process proceeds to the block “cutout range information acquisition process” (ST3) after completion of the block “display process” (ST5). As a result, the cut-out range can be directly designated directly after the creation of another window screen, so that the operation for creating another window screen can be simplified.

  As described above, in the second embodiment, the effect at the time of creating another window screen in the first embodiment, that is, the improvement in the visibility of the monitoring control screen and the reduction in the communication amount can be realized. There is an effect that the operation for creating the separate window screen can be simplified.

Embodiment 3 FIG.
Embodiment 3 of the present invention will be described with reference to the drawings.
The third embodiment relates to a monitor control system display device capable of performing another window screen creation process in which a range can be specified by specifying one point.

In the first embodiment, two points of a start point and an end point are specified in specifying the cutout range. However, it is possible to realize another window screen creation process by specifying only one point.
FIG. 12 shows a schematic diagram of the operation for specifying the cutout range.
First, the center point of the range to be specified is specified by the pointing device 5, and if the button of the pointing device 5 is continuously pressed as it is, the start point and the end point are extended on the diagonal line, thereby specifying the width of the rectangle. That is, this is an input form in which the position of the start point and the end point can be determined based on the coordinates of the designated center point and the length of the pressing time.
In this case, the rectangle is a square, but the range designation operation for designating the start point and the end point can be simplified.

  In the third embodiment, a separate window screen is created in addition to the effect of creating a separate window screen in the first embodiment, that is, the effect of improving the visibility of the monitoring control screen and reducing the amount of communication. This has the effect of simplifying the cutout range designating operation.

Embodiment 4 FIG.
A fourth embodiment of the present invention will be described with reference to the drawings.
The fourth embodiment relates to a monitoring control system display device that can be connected by combining the created separate window screens.
As shown in FIG. 13, it is possible to display distant parts on the original screen next to each other or to combine different window screens created from different screens.

When specifying the cut-out range, two separate window screens are arranged side by side to specify a range including both window screens as the cut-out range of the separate window screen. As a result, new screen definition data including screen definition data of both window screens before combining is generated in the separate window screen screen data generation of the block “Generate another window screen definition data” (ST43). Display as a screen.
Specifically, in the combined separate window screen, drawing is realized by dividing the inside of a single window into a plurality of areas and assigning the screen definition data before combining to each area as they are. Accordingly, the screen definition data of the combined separate window screen may be only the data defining the screen definition data before combining and the allocation of the area to be drawn.
Thereby, since a plurality of window screens can be displayed as a single window screen, visibility is improved and operations such as movement of the window screen can be simplified.

  In the fourth embodiment, the effect of creating another window screen in the first embodiment, that is, the effect of improving the visibility of the monitoring control screen and reducing the amount of communication can be realized. Since it can be displayed as one window screen, the visibility is further improved and operations such as moving the window screen can be simplified.
