Description

  The present invention relates to a screen display data editing apparatus and a screen display data editing program for creating screen display data for displaying operation states of various devices and apparatuses on a display device to which the various apparatuses and devices are connected.

Generally, FA (Factory
Automation) system consists of various devices and devices connected via a communication network, such as input devices such as switches and sensors, output devices such as actuators and temperature control devices, and control devices that control input devices and output devices. The The operation of the control device is defined by a control program created using a ladder diagram symbolizing the relay circuit, and the control program can be freely edited by a user using program creation software such as a ladder editor. Therefore, a control device used in the FA system is called a PLC (Programmable Logic Controller). The PLC holds a large number of state data such as state data indicating the state of the input signal from the input device, state data indicating the state of the output signal to the output device, and state data indicating the operation state inside the PLC. . When the PLC control program is executed, a process for changing the state data of the output device is performed by referring to the state data of the input device and executing predetermined arithmetic processing.

  In the FA system, a display device such as a liquid crystal display having a touch panel may be connected to monitor input / output devices connected to the PLC and an operation state (state data) of the PLC (for example, Patent Document 1). reference). On the screen of such a display device, various component images such as lamps, meters, and graphs are displayed as screen components. The layout of various component images displayed on the screen of the display device can be freely edited by the user using screen display data creation software such as a drawing editor. In the display device to which the screen display data created using the screen display data creation software is transferred, the status data of the input / output device connected to the PLC, for example, is read from the PLC, and the component image is displayed according to the status data. Changes (for example, the lamp turns on / off or the meter's needle moves). Thereby, the user can monitor the operation state of the input / output device connected to the PLC.

  Here, when creating screen display data of a screen to be displayed on the display device using the screen display data creation software, there are cases where it is desired to use the screen display data of the sample screen provided by the display device manufacturer. Since the layout of various component images and the like are already determined for the sample screen, the user can improve the efficiency when creating the screen display data by using the sample screen well. If the screen display data creation software has a screen display data import function, the user can import sample screens relatively easily by using this import function (for example, import setting wizard). Can be executed.

  However, the conventional import function has the following problems. Among the component images displayed on the display device, there is a component image to which common reference data that is commonly referred to from a plurality of component images is assigned. For example, it is a trend graph (part image thereof) that captures the state data held in the PLC every time a predetermined sampling trigger occurs and monitors the time transition of the state data with the horizontal axis as the time axis. . Examples of common reference data that is commonly referred to in the trend graph include the number of state data to be imported into the display device and data for setting a storage area (memory area in the PLC). As a specific example, when there are three trend graph component images on one or a plurality of pages, common reference data of identification ID 1 is assigned to trend graph 1 and trend graph 2, and trend graph 3 has For example, the common reference data of the identification ID 2 is assigned.

  When importing such common reference data, the user is forced to perform complicated operations. Specifically, if the identification ID (for example, identification ID1) of the common reference data to be imported overlaps with the identification ID (for example, identification IDs 1 to 3) of the common reference data that is currently being edited, that common If the reference data is imported as it is, a part of the user asset data (for example, setting data of the identification ID 1) is lost. Therefore, in order to avoid this, it is necessary to change the identification ID of the common reference data to be imported by using the import setting wizard or the like (for example, from identification ID1 to identification ID4), which makes the user cumbersome work. It will be tough. In particular, when importing together the common reference data and the screen page data in which one or more component images to which the common reference data is assigned are arranged on the screen, the identification ID of the common reference data is changed. However, it is not sufficient, and it is necessary to change the common reference data assigned to the component image individually one by one as the identification ID of the common reference data is changed. Specifically, the user needs to open the setting screen individually for the component images to which the common reference data is assigned after the import and change the identification ID of the common reference data. The conventional import function forcing such complicated work has room for improvement in order to improve usability.

  The present invention has been made in view of the above points, and an object of the present invention is to reduce a user's work load and improve usability when importing screen display data for displaying a screen on a display device. A screen display data editing apparatus and a screen display data editing program are provided.

  The screen display data editing device according to the present invention is a screen display data editing device capable of editing screen display data for displaying a screen on a display device connected to the programmable logic controller.

Common reference data that is commonly referred to. In the screen display data editing apparatus according to the present invention, the editing target receiving unit that receives the designation of the screen display data as the editing target from the user, and the screen display data being edited designated by the editing target receiving unit are imported. As an import target, an identification number for identifying common reference data is acquired from the import target receiving means for accepting designation of new screen display data from the user, the screen display data being edited, and the screen display data to be imported. Based on the search result of the duplicate search means, the duplicate search means for searching for the duplicate of the identification number acquired by the identification number acquisition means, the screen display data being edited and the screen display data to be imported. To avoid duplication of identification numbers. An identification number changing unit that changes the identification number of the reference data, and a component image that is referenced by the common reference data that has been changed by the identification number changing unit, follows the change by the identification number changing unit and changes the common reference data Part image setting changing means for changing the setting of the part image so that the identification number is changed, and the screen display data in which the screen display data being edited is changed by the identification number changing means and the part image setting changing means. And an import execution means for executing the import.

  According to such a configuration, the identification number acquisition unit acquires the identification number for identifying the common reference data from the screen display data being edited and the screen display data to be imported, and the duplicate search unit acquires the identification number. Duplicate numbers are searched, and the identification number changing means changes the identification number of the common reference data included in the screen display data to be imported so as to avoid duplication of identification numbers, so the user imports the common reference data When doing so, the labor of changing the identification number to avoid duplication can be saved. In particular, since the component image setting changing means also changes the setting of the component image following the change of the identification number, the user individually opens the setting screen for the component image to which the common reference data is assigned, and sets the identification number. You can save time and effort to make changes. In this way, the work burden on the user can be reduced and the usability can be improved.

  Further, in the screen display data editing apparatus according to the present invention, the identification number of the common reference data included in the screen display data to be imported is changed based on the search result of the duplicate search means so as to avoid duplication of the identification number. Table creation means for creating the identification number change table is provided, and the identification number change means changes the identification number of the common reference data included in the screen display data to be imported based on the identification number change table. Such a configuration may be adopted. In this way, by creating the identification number change table before the import is started by the import execution means, the identification number change means can change the setting at the import destination of the common reference data only by referring to the table. The processing load on the number changing means can be reduced.

  The screen display data editing apparatus according to the present invention includes a table display means for displaying the identification number change table on the display unit of the screen display data editing apparatus, and the user is permitted to change the identification number by the identification number change table in the display unit. And a change permission receiving means for receiving the change number, and the identification number changing means changes the identification number of the common reference data included in the screen display data to be imported when the change permission receiving means permits the change of the identification number. You may make it the structure which does. As a result, it is possible to confirm with the user whether or not the import can be performed after avoiding duplication of the identification numbers of the common reference data, and thus it is possible to prevent the import not intended by the user.

  Further, the screen display data editing apparatus according to the present invention is configured such that the display unit is provided with identification number edit accepting means for accepting editing from the user for the identification number changed by the identification number change table. Good. Thereby, a user who does not want to avoid duplication of the identification number of the common reference data can overwrite the identification number via the identification number editing accepting means, and the usability can be further improved.

  In the screen display data editing device according to the present invention, the identification number changed by the identification number edit accepting unit is duplicated with the identification number of the common reference data included in the screen display data being edited. In the case of editing as described above, a configuration may be provided in which highlighting means is provided that highlights the edited identification number. Accordingly, when the identification number of the common reference data is overwritten, the user can be alerted, and the identification number can be prevented from being overwritten against the user's intention.

  The screen display data editing apparatus according to the present invention avoids duplication when the page number of the page constituting the screen page data is duplicated in the screen display data being edited and the screen display data to be imported.

It may be configured to execute the import. Thereby, for example, when it is desired to import the screen page data of the sample screen provided by the display device manufacturer into the screen page data currently being edited, the page number for identifying the screen page data of the sample screen to be imported, Even when the page number for identifying the screen page data currently being edited partially overlaps, it is possible to easily avoid duplication of the page number, and as a result, one of the screen page data currently being edited as user assets. It is possible to prevent the part from being lost.

  In the screen display data editing apparatus according to the present invention, a page switching number for switching to a screen with a page number different from the page number of the page on which the part image is arranged is set in the component image. The above-described component image setting changing means includes the page number changing means for the screen switching component image arranged on the screen of the page number to be changed by the page number changing means. Change the setting of the screen switching part image so that the page switching number is changed following the change, and the import execution means is configured to execute the import of the screen display data with the changed page switching number. Also good. Thereby, the user can save the trouble of opening the setting screen individually for the imported screen switching part image and changing the page switching number, and can further reduce the user's workload.

The device includes a bit device (input bit device) that is turned on / off based on an input signal from the input device 601 and a bit device (output bit device) that is turned on / off to control the operation of the output device 602. There are word devices that store numerical data instead of on / off. The device also has a device type indicating whether it is a bit device or a word device, and a device number for managing a plurality of data having the same device type. For example, the device “DM0000” shown in FIG. 2 has a device type “DM” and a device number “0000”.

  The display device 200 is mainly a device for monitoring the operation state of the PLC 300, and is connected to the PLC 300 via, for example, a serial communication cable. The display device 200 performs data communication with the PLC 300, acquires state data in the PLC 300, that is, a device value, and performs screen display based on the device value. In addition, an instruction can be given to the PLC 300 using data communication. That is, the device value stored in the device in the PLC 300 can be rewritten. For example, when the user presses a switch component image displayed on the screen of the display device 200, a write command is sent from the display device 200 to the PLC 300. For example, a device value is assigned to the device assigned to the switch component image. Is written. When the control program of the PLC 300 is executed, a control command is issued to the output device 602 connected to the PLC 300, for example, with reference to the written device value.

  The screen display data editing device 100 is a device for creating screen display data for displaying the operation state of the PLC 300 on the screen of the display device 200. If necessary, the screen display data editing device 100 is connected to the display device 200 via a serial communication cable or the like. The connected and created screen display data is transferred to the display device 200. For example, a personal computer in which screen display data creation software is installed can be used as the screen display data editing apparatus 100. The user uses the screen display data editing device 100 to determine the layout of various component images such as switches, meters, and graphs displayed on the screen of the display device 200, and to assign the individual component images to the devices of the PLC 300.

Thereby, based on the input signal from the input device 601 (FIG. 1), the device to which the input device 601 is assigned is turned on / off, and based on this, predetermined arithmetic processing is executed, and the output device 602 (FIG. 1). The output device 602 is controlled by turning on / off the device to which () is assigned. The device memory 303 is a memory in which device values (status data) of devices to which the input device 601 and the output device 602 are assigned are stored. In addition, state data indicating the operation state inside the PLC 300 is also stored as a device value of the internal device. When the control program is executed, first, after the device value of the output device assigned to the output device 602 is transferred to the output device 602, the value received from the input device 602 is input as the status data of the input device 602. It is transferred to the device (so-called automatic refresh). Then, after the control program is executed for each instruction in order from the top step, post-processing such as communication processing with an external device and error check of the entire system is performed.

As will be described later, the common reference data is included as one of the system setting data, and other system setting data includes the overall system setting of the display device 200 main body, device comments, and the device in the PLC 300. Various programs such as a program for reading a device value are included. In addition, when state data indicating the internal operation state of the display device 200 is stored as a device value of an internal device, a program for reading the device value of the internal device is also included.

  As shown in FIG. 3, the screen display data editing apparatus 100 includes a control unit 101, an input unit 102, a display unit 103, an HDD (hard disk drive) 104, a memory 106, a communication means (communication interface 107), and the like. ,have. The control unit 101 is realized by a CPU or the like, and is connected to each hardware unit via a bus. The control unit 101 controls the operation of each unit of hardware and exhibits various software functions according to the computer program stored in the HDD 104.

Hereinafter, a (software-like) functional configuration of the screen display data editing apparatus 100 will be described.

[Function configuration]
FIG. 4 is a block diagram showing a functional configuration of the screen display data editing apparatus 100 according to the present embodiment.

  As shown in FIG. 4, the screen display data editing apparatus 100 includes an edit target receiving unit 11, an import target receiving unit 12, an identification number acquisition unit 13, a duplicate search unit 14, a table creation unit 15, and a table display. Means 16, identification number edit accepting means 17, highlighting means 18, changing means 20, change permission accepting means 25, and import executing means 26. The changing unit 20 includes an identification number changing unit 21, a page number changing unit 22, a device changing unit 23, and a component image setting changing unit 24. The functions as these means are realized by the control unit 101 shown in FIG. 3, computer programs stored in the HDD 104, and hardware such as the memory 106.

  First, the edit target accepting unit 11 and the import target accepting unit are units for accepting data designation from the user via the input unit 102. Specifically, the edit target accepting unit 11 accepts designation of screen display data as an edit target from the user, and the import target accepting unit 12 imports to the screen display data being edited designated by the edit target accepting unit 11. As a target to be imported, designation of new screen display data is accepted from the user. The screen display data may be designated by screen display data stored in the HDD 104 or the portable recording medium 105 or screen display data acquired from an external communication network or the like via the communication unit 107. There may be. Of course, the portable recording medium 105 may be a non-disk type recording medium such as a USB memory.

The identification number acquisition unit 13 is a unit that acquires an identification number for identifying the common reference data from the screen display data being edited and the screen display data to be imported. That is, an identification number for identifying common reference data included in the screen display data being edited,
This is means for acquiring an identification number for identifying common reference data included in screen display data to be imported. There may be one or more identification numbers.

  The duplication search means 14 is a means for searching for duplication of the identification numbers acquired by the identification number acquisition means 13 between the screen display data being edited and the screen display data to be imported. That is, the identification number for identifying the common reference data included in the screen display data being edited is compared with the identification number for identifying the common reference data included in the screen display data to be imported. It is a means for searching the duplication location. The overlapping part may be one place or may be a plurality of places. For example, when ID0 and ID1 exist as identification numbers of common reference data included in screen display data being edited, while ID0 exists as an identification number of common reference data included in screen display data to be imported, both Are compared to recognize that ID0 is duplicated.

  Based on the search result of the duplicate search means 14, the table creation means 15 changes the identification number of the common reference data included in the screen display data to be imported so as to avoid duplication of the identification number for identifying the common reference data. This is means for creating the identification number change table. The identification number change table is a table showing how the identification number of the common reference data included in the screen display data to be imported is changed and set in the screen display data being edited as the import destination. In other words, it is import setting information (conversion table) for determining the initial value of the identification number of the common reference data included in the screen display data to be imported when it is imported into the screen display data being edited. It can be said that there is. For example, when ID0 exists as the identification number of the common reference data included in the screen display data to be imported, this ID0 is a part of the identification numbers ID0 and ID1 of the common reference data included in the screen display data being edited. When they overlap, ID2 is determined as an initial value in the identification number change table so as to avoid duplication. As a result, an identification number change table in which ID0 and ID2 are associated is created (ID0 => ID2).

  In addition, as the identification number change (conversion) table, the page number change (conversion) table of the pages constituting the screen page data, the identification ID change (conversion) table of the trend graph (part image), Alarm (part image) identification ID change (conversion) table, message block number change (conversion) table, Windows (registered trademark) font registered character ID change (conversion) table, PLCDF file No. Various tables such as a change (conversion) table, a worksheet ID change (conversion) table, a PLC model change (conversion) table, and a device change (conversion) table.

  FIG. 5 is an image diagram (an example) of an identification number change table. As shown in FIG. 0, alarm ID0, trend graph ID1, and trend graph ID2. Then, based on the search result of the duplicate search means 14 described above, the screen page No. 10, initial values of alarm ID1, trend graph ID3, and trend graph ID4 are determined. Such an identification number change table is displayed on the display unit 103 via the table display means 16. That is, the table display unit 16 is a unit for displaying the identification number change table on the display unit 103 of the screen display data editing apparatus 100.

  The identification number edit accepting unit 17 has a function of editing the identification number change table created by the table creating unit 15. For example, if the user wants to edit the right column of the identification number change table shown in FIG. For example, as shown in FIG. 6, in the right column of the identification number change table shown in FIG. 5, the trend graph ID3 can be changed to the trend graph ID1 (by a pull-down menu or the like via the input unit 102). That is, when the screen display data to be imported is imported into the screen display data being edited, the identification number edit accepting means 17 can change the initial value of the identification number. As described above, the identification number edit accepting unit 17 has a function of accepting editing from the user for the identification number changed by the identification number change table in the display unit 103.

  However, when the edit as shown in FIG. 6 is performed by the identification number edit accepting unit 17, if the import is executed as it is, the trend graph ID1 is overwritten. There is no particular problem when the user performs the editing as shown in FIG. 6 with the understanding of overwriting, but when the user makes an erroneous editing without recognizing that the trend graph ID1 is duplicated, the user Assets (setting contents of trend graph ID1 included in the screen display data being edited) will be lost. Therefore, the highlighting means 18 is edited by the identification number edit accepting means 17 so that the identification number changed by the identification number change table overlaps with the identification number of the common reference data included in the screen display data being edited. The identification number edited on the display unit 103 is highlighted. Specifically, for example, as shown in FIG. 7, the background of the trend graph ID1 is colored. Note that the trend graph ID1 may be highlighted in red or bold.

  The identification number changing means 21 changes the identification number of the common reference data included in the screen display data to be imported based on, for example, an identification number change table as shown in FIG. For example, referring to the identification number change table shown in FIG. 5, alarm ID0, trend graph ID1, and trend graph ID2 are changed to alarm ID1, trend graph ID3, and trend graph ID4, respectively.

  Further, the page number changing unit 22 also changes the page number of the page included in the screen page data to be imported based on, for example, an identification number changing table as shown in FIG. For example, referring to the identification number change table shown in FIG. 0, screen page No. Change to 10. As described above, the page number changing means 22 imports to avoid duplication when the page numbers of the pages constituting the screen page data overlap between the screen display data being edited and the screen display data to be imported. Change the page number of the screen page data included in the target screen display data.

  In this embodiment, the identification number changing unit 21 and the page number changing unit 22 change the identification number of the common reference data included in the screen display data to be imported based on the identification number changing table. However, it is not always necessary to create the identification number change table. For example, you may make it change sequentially or simultaneously about the identification number of each common reference data, without creating an identification number change table. That is, the identification number changing unit 21 and the page number changing unit 22 set the identification number of the common reference data included in the screen display data to be imported so as to avoid duplication of the identification number based on the search result of the duplication search unit 14. Has the function to change.

  The device changing unit 23, when the screen function data being edited and the screen display data to be imported have duplicate devices that function as virtual memory areas for storing parameter values referred to by the component images, It has a function to change the device included in the screen display data to be imported so as to avoid it. The device changing unit 23 may also be configured to refer to a device change table corresponding to the above-described identification number change table.

  The component image setting changing unit 24 changes the identification number of the common reference data following the change by the identification number changing unit 21 with respect to the component image to which the common reference data to be changed by the identification number changing unit 21 is referred. This is means for changing the setting of the component image. For example, in the identification number change table shown in FIG. 5, when there is one or more trend graphs (part images) referring to the trend graph ID2, the screen display data to be imported is being edited for each trend graph. When imported into the display data, the trend graph ID2 is automatically changed to the trend graph ID4 as the identification number of the common reference data. This eliminates the need for the user to open the setting screen for each trend graph individually in the screen display data being edited after the import is completed, and to change the trend graph ID2 to the trend graph ID4 one by one.

  The change permission accepting unit 25 changes the identification number by the identification number changing unit 20, changes the page number by the page number changing unit 22, changes the device by the device changing unit 23, and changes the component image setting by the component image setting changing unit 24. Is a means for accepting change permission from the user. Thereby, when importing common reference data, it can alert | report to a user that duplication avoidance of an identification number is performed. The change unit 20 changes the identification number of the common reference data included in the screen display data to be imported when the change permission receiving unit 25 permits the change of the identification number, the page number, the device, and the part image setting. The target for accepting the change permission may be all of the identification number changing means 20, the page number changing means 22, the device changing means 23, and the component image setting changing means 24, or only a part of the means. May be.

  The import execution means 26 has a function of executing the import of the screen display data that has been changed by the changing means 20 with respect to the screen display data being edited. That is, the import execution means captures the screen display data changed by the identification number changing means 20, the page number changing means 22, the device changing means 23, and the component image setting changing means 24 into the screen display data being edited. Process. For example, when the screen display data being edited is stored in some file A and the screen display data to be imported is also stored in some file B, the import target screen display data is loaded into the file A. . As described above, import refers to processing that can be used when executing an import destination file through data conversion.

  As described above, according to the screen display data editing apparatus 100 capable of exhibiting the function of each unit illustrated in FIG. 4, the user can easily import the sample screen through the GUI. Details of importing a sample screen using a GUI will be described below.

[Display screen example]
8 to 23 are diagrams illustrating an example of a screen (GUI) displayed on the display unit 103 of the screen display data editing apparatus 100. FIG. The user performs a predetermined operation on the display unit 103 of the screen display data editing apparatus 100 via the input unit 102 to start the screen display data creation software, thereby displaying the screen of the drawing editor shown in FIG. be able to.

  FIG. 8 is a diagram illustrating a state in which screen display data is being edited on the display unit 103 of the screen display data editing apparatus 100. After starting the screen display data creation software in the screen display data editing apparatus 100, the user clicks “Open” (not shown) in the “File” menu at the upper left of FIG. 8, for example, to open the file to be edited. Thus, it is possible to specify screen display data to be edited.

  On the screen of the drawing editor shown in FIG. 8, a system setting tab 1001 and a screen tab 1002 are displayed at the lower left. Of these, the screen tab 1002 is a tab for editing the screen page data, and when the user clicks on the screen tab 1002, one or a plurality of currently edited tabs are displayed in the workspace above the screen tab 1002. INDEX of the page can be displayed. FIG. 8 shows a state when the screen tab 1002 is clicked. The currently edited screen is a cover screen with a page number 0000, a menu screen with a page number 0001, and a unit_outline with a page number 0010. A screen of unit_detail 1 of page number 0020, a screen of unit_detail 3 of page number 0022, a screen of bit monitor 1 of page number 0030, a screen of bit monitor 2 of page number 0031, It consists of ... As described above, the page number is a number for uniquely specifying a screen to be displayed on the display device 200, and a duplicate page number cannot be assigned to one screen display data.

  The screen specified by each page number is hierarchical. For example, when the bit monitor 1 of the page number 0030 is clicked, a bit monitor 1_B 1003 appears immediately below, and this shows a screen that is the base of the bit monitor 1. Although not shown in FIG. 8, it is also possible to create one or a plurality of windows as pop-up windows on the screen of the bit monitor 1_B 1003. When the user clicks the bit monitor 1_B 1003 on the workspace, the screen content can be displayed in the edit area 1004 on the right side. FIG. 8 shows a state where the screen of the bit monitor 1_B 1003 is being edited. The screen display data to be edited is designated by the function of the edit target accepting unit 11 described above.

  Here, the sample screen import procedure will be described in detail. 9 to 23 are examples of wizard screens displayed when importing sample screens. For example, the screen shown in FIG. 9 can be displayed by clicking “Import” (not shown) in the “File” menu in the upper left of FIG. 8 and selecting a file to be imported. In the upper part of the wizard screen shown in FIG. 9, “Step 1: PLC model setting”, “Step 2: Import target setting”, and “Step 3: Device setting” are displayed in order from the left, and the user follows this procedure. Sample screens can be easily imported by making decisions. In FIG. 9, the import target is displayed on the left side and the data being edited is displayed on the right side. As the PLC model of the import destination, the PLC model 1011 can be selected from the pull-down menu in the editing data on the right side. Note that the PLC model of the import destination is, for example, the model of the PLC 300 to which the display device 200 shown in FIG. 1 is connected. The screen display data to be imported is designated by the function of the import target accepting unit 12 described above.

  When the selection of the PLC model is completed, a “Next” button 1012 is clicked. Then, the setting of Step 1 shown in FIG. 9 is completed, and the process proceeds to the setting of Step 2 shown in FIG. In the wizard screen shown in FIG. 10, the user selects an object to be actually imported from the screen display data to be imported. On the left side of FIG. 10 are “screen” for selecting screen page data as an object to be imported, and “VT main body system settings” to “worksheet” for selecting each system setting data as an object to be imported. Is displayed. Among these, for example, “trend graph” and “alarm” are common to the same type and multiple component images (“trend graph” component image and “alarm” component image, respectively) arranged on one or more pages. It is an example of common reference data referred to as. FIG. 10 shows a state when “screen” is selected as an import target.

  A detailed setting column is displayed at the center and right side of FIG. 10, and a screen (base / window 1.2.3) tab 1021 and a global window tab 1022 are displayed therein. FIG. 10 shows a state when the screen tab 1021 is clicked. In the screen tab 1021, page numbers are simply displayed. For example, page number 0000 is displayed as page number 0, and page number 0010 is displayed as page number 10.

  On the left side of the screen tab 1021, the cover of page number 0, the menu of page number 1, the unit of page number 10_outline,..., The trend graph of page number 30, and the graph description of page number 31 are to be imported. Each of and is displayed as a list. On the other hand, on the right side in the screen tab 1021, as an import result preview, the cover of page number 0, the menu of page number 1, the unit_outline of page number 10,..., Bit monitor 1 of page number 30, page Each of the bit monitor 2 with the number 31, the word monitor 1 with the page number 40, and the alarm with the page number 102 is displayed as a list. That is, at the stage where no import target has been selected, each screen acquired from the screen page data being edited is displayed in a list on the right side in the screen tab 1021. In the center of the screen tab 1021, an import target selection button 1024 and an import target release button 1025 are arranged vertically. In addition, after selecting an import target, the user can D & D (drag and drop) the grid on the import result preview instead of clicking the import target selection button 1024. Here, an example using the import target selection button 1024 will be described.

  As shown in FIG. 11, the user clicks only the desired page to be imported among the pages constituting the screen page data to be imported, for example, the trend graph of page number 30 and the graph description of page number 31. Then, their background is colored gray. Thereafter, when an import target selection button 1024 is clicked, an import destination setting screen 1026 appears in a pop-up window. On the import destination setting screen 1026, the user can change the first page number 1027 of the import destination to a desired number. In FIG. 11, the original page number 30 is displayed as it is, but for example 32 or so as not to overlap with the pages constituting the screen page data being edited (page numbers listed on the right side in the screen tab 1021). 33, 100 or 101 can be changed. In particular, the user can automatically change to a page number that does not overlap with the page constituting the screen page data being edited by clicking the “search for empty block” button 1028 on the import destination setting screen 1026. . For example, as shown in FIG. 12, the first page number 1027 of the import destination is changed to 100. Then, when an OK button is clicked on the import destination setting screen 1026 shown in FIG. 12, the trend graph of page number 30 and the graph description of page number 31 existing on the left side in the screen tab 1021 are displayed on the screen as shown in FIG. It is also copied to the right side in the tab 1021. At this time, the page number of the trend graph is changed to 100 changed in FIG. 12, and the page number of the graph description is changed to 101 changed in FIG.

  Next, the setting of the “trend graph” displayed on the left side of FIG. 13 will be described in detail. FIG. 14 is a diagram illustrating a state when the “trend graph” displayed on the left side of FIG. 13 is clicked by the user. In the center and the right side of FIG. 14, a detailed setting column is displayed, and a trend graph ID change table 1041 is displayed therein. The trend graph ID change table 1041 is one of the identification number change tables created by the table creation means 15. In the trend graph ID change table 1041, ID0 and ID1 are displayed from the top as import targets on the left side, and ID2 and ID3 are displayed from the top as import destinations on the right side. That is, ID0 is associated with ID2, and ID1 is associated with ID3.

  In the trend graph ID change table 1041 shown in FIG. 14, the import target and the import destination (corresponding to the “import result preview” shown in FIG. 10) are displayed on the left and right, as in FIG. Here, details of the trend graph ID change table 1041 will be specifically described with reference to FIGS. 15 and 16.

  FIG. 15 shows a state in which the “editing” screen display data is opened via the “file” menu and the system setting tab 1001 is clicked on the screen of the drawing editor shown in FIG. FIG. 16 shows a state when the screen display data “to be imported” is opened via the “file” menu on the screen of the drawing editor shown in FIG. 8 and the system setting tab 1001 is clicked.

  As shown in FIG. 15, items related to system settings such as VT system settings, device comments, trend graphs, alarms, messages, etc. are displayed in the workspace when the system settings tab 1001 is clicked. Is done. Among these, the trend graph is a component image for capturing the state data held in the PLC 300 into the display device 200 every time a predetermined sampling trigger occurs and monitoring the time transition of the state data with the horizontal axis as the time axis. It is. Then, in order to determine which state data of the state data held in the PLC 300 is to be monitored over time, settings relating to the trend graph are included in the system settings. The contents set in this system setting are stored (in a storage unit such as the HDD 104) with a trend graph ID attached thereto. In this way, by including the settings related to the trend graph in the system settings, the setting contents of the trend graph ID can be referred to in common from a plurality of trend graphs arranged on one page or a plurality of pages. As a result, the user repeats the settings such as which state data should be monitored over time and what is the data acquisition mode simply by specifying the trend graph ID for each trend graph component image. It does not have to be.

  In the present embodiment, settings relating to two types of trend graphs are stored, and identification numbers of trend graph ID0 and trend graph ID1 are assigned respectively. Therefore, when the trend graph displayed in the workspace of FIG. 15 is clicked, ID0 to ID3 (the trend graph ID is simply abbreviated as ID) appear immediately below, and only the icons of ID0 and ID1 among them are line graphs. (The settings of ID2 and ID3 are not particularly saved, so these icons are simply square frames). When the user clicks ID0 shown in FIG. 15, the setting content of ID0 can be edited on the right side of the workspace.

  In the center and the right side of FIG. 15, a state in which the setting content of the trend (ID0), that is, the trend graph ID0 is edited is shown. In the data acquisition mode 1031, for example, “normal” or “extended” having a trend monitoring cycle later than this can be selected, and FIG. 15 shows that “normal” is selected. The number of trends 1032 is the number of trend graph state data to be sampled, and FIG. 15 shows that “2” is selected. That is, two state data are sampled from the PLC 300 and stored in the built-in memory (HDD 104 or memory 106) of the display device 200. The trend sample device 1033 is a device (reference device) that stores state data for monitoring time transition, and FIG. 15 shows that the device MW0020 (internal timer) is selected. The data length 1034 indicates the data length of the reference device, and can be selected from one word or two words, for example. In addition, below the data length 1034, a column for designating a bit device serving as a sampling trigger is provided.

  In this way, the setting content of the trend graph ID0 can be edited in the screen display data being edited. On the other hand, the trend graph ID 0 is also set in the screen display data to be imported as in FIG. 15 (see FIG. 16). In particular, FIG. 16 is different from FIG. In FIG. 15, the trend number 1032 is set to 2 in the screen display data being edited, whereas in FIG. 16, the trend number 1032 is set to 4 in the screen display data to be imported.

  If the user imports the setting contents of the trend graph ID 0 shown in FIG. 16 as it is, the setting contents of the trend graph ID 0 in the screen display data being edited are overwritten, and the setting contents of the trend number 1032 in the trend graph ID 0 are changed. The number changes from 2 to 4, and the common reference data (FIG. 15) in which the trend number 1032 is set to 2 cannot be left as a user asset.

  In view of this, in the screen display data editing apparatus 100 according to the present embodiment, the screen display data being edited and imported by the identification number acquisition means 13 so that the common reference data shown in FIG. The trend graph ID is acquired as one of the common reference data from the target screen display data, the duplicate search unit 14 searches for the duplicate trend graph ID, and the table creation unit 15 avoids the trend graph ID duplication. As described above, the trend graph ID change table 1041 in which the trend graph ID included in the screen display data to be imported is changed is created and displayed on the display unit 103 by the table display means 16.

  As a result, in the trend graph ID change table 1041 shown in FIG. 14, the trend graph ID0 (ID0) and the trend graph ID1 (ID1) are displayed on the left as import targets, and the import destination of the trend graph ID0 on the right ( Trend graph ID2 is displayed (so as to avoid duplication with ID0 and ID1), and trend graph ID3 is displayed as an import destination of trend graph ID1 (so as to avoid duplication with ID0 and ID1).

  Note that the trend graph ID acquired from the common reference data being edited may be displayed together on the right side of the trend graph ID change table 1041 as in the import result preview shown in FIG. That is, for example, the trend graph ID change table 1043 shown in FIG. 17 may be displayed. In addition, there are various display modes of the trend graph ID change table 1043. For example, as shown in FIG. 18, the trend graph ID identification number is fixed in a row and the import destination is specified by an arrow. Good.

  Further, in the screen display data editing apparatus 100 according to the present embodiment, the trend graph ID change table 1041 can be edited by the identification number edit receiving means 17. Specifically, as shown in FIG. 19, for example, the trend graph ID0 can be designated as the import destination of the trend graph ID0 (it may be selected from a pull-down menu or the like). As a result, the user who thinks that the trend graph ID0 may be duplicated can easily overwrite the setting contents of the trend graph ID0, and the usability of the screen display data editing apparatus 100 is improved. However, in order to prevent the setting contents of the trend graph ID0 from being overwritten against the user's intention, in this embodiment, the highlighting means 18 highlights the overlapping portions. For example, as shown in FIG. 20, in order to highlight that the setting content of the trend graph ID0 is overwritten, the character “ID0” is bold. In addition, “ID0” may be displayed in red, the background of the cell of “ID0” may be colored, and the manner of highlighting is not questioned.

  Returning to FIG. 14, a check box is provided in the leftmost column of the trend graph ID change table 1041, so that the user can select the setting contents of the trend graph ID to be imported. For example, it is possible to make only the trend graph ID1 of the trend graph ID0 and the trend graph ID1 included in the screen display data to be imported as the import target. In FIG. 14, all trend graph IDs are selected.

  Further, in the present embodiment, only the “trend graph” has been described among the system settings shown on the left side of FIG. 14, but the same applies to other system settings. For example, “alarm” has a plurality of common reference data in which alarm detection devices, alarm messages, and the like are set, and an alarm ID is assigned to each common reference data. Therefore, similarly to the trend graph ID change table 1041, an alarm ID change table (not shown) may be displayed on the display unit 103. The identification number editing accepting unit 17 and the highlighting display unit 18 may edit the alarm ID, or may highlight the overlapping alarm ID.

  In this way, when the import target setting of Step 2 shown in FIG. 14 is completed, the user clicks the “Next” button 1042. Then, the setting of Step 2 is completed, and the process moves to the setting of Step 3 shown in FIG. In the wizard screen shown in FIG. 21, settings are made so that the device set in the screen display data to be imported does not become a duplicate device or an unset device at the import destination. The background of providing Step 3 will be described. For example, when the model is converted into a dissimilar model and imported in Step 1 of FIG. 9, the device settings may not match the changed model. In this case, there is a possibility that a part of the device set in the screen display data to be imported is converted into an unset device. If some or all of the devices are converted to unconfigured devices, the device type and device number information used in the screen display data to be imported will be lost, so the user must reconfigure It becomes very troublesome. Thus, in the screen display data editing apparatus 100 according to the present embodiment, Step 3 is provided in the import setting wizard.

  As shown in FIG. 21, a device change table 1050 is displayed at the center of the screen, and a table in which a data type 1051, a continuous number 1052, an import target device 1053, and an import destination device 1054 are arranged side by side. It is displayed. The data type 1051 indicates whether it is a bit device or a word device, the continuous number 1052 indicates how many devices are continuous from the head device, and the import target device 1053 indicates the screen display of the import target. This indicates a device set in the data, and the import destination device 1054 indicates a device that is converted when imported to the screen display data being edited. The import target device 1053 and the import destination device 1054 indicate the head device when the continuous number 1052 is one.

  The device change table 1050 shown in FIG. 21 can be created in the same manner as the trend graph ID change table 1041 described above. That is, the screen display data editing apparatus 100 according to the present embodiment acquires a list of devices set in each screen display data from the screen display data being edited and the screen display data to be imported, and changes the device. A table 1050 is created. Similar to the trend graph ID change table 1041 described above, device duplication may be searched and a device change table 1050 in which devices are changed so as to avoid duplication may be created. Further, the contents of the device change table 1050 may be edited in the same manner as the trend graph ID change table 1041 described above.

  In FIG. 21, as shown in the row of R00000 for the import target device 1053, the overlapping portion is highlighted. That is, the device R00000 indicates that the device is already set in the screen display data being edited. The user can edit R00000 in the import destination device 1054. For example, when the R00000 device is clicked, a device setting screen 1056 shown in FIG. 22 is displayed, and the data type 1057 and the PLC device 1058 are edited therein. In FIG. 22, the PLC device 1058 is edited from R00000 to R99900. Thereafter, when an OK button on the device setting screen 1056 is clicked, as shown in FIG. 23, the device R99900 of the import destination device 1054 is set as the destination device to which the device R00000 of the import target device 1053 is imported. With the overlap avoidance, the highlighted display of the line R00000 is canceled as shown in FIG.

  In this way, when the device setting in Step 3 shown in FIG. 23 is completed, the user clicks an “execute import” button 1055. Then, the identification number changing unit 21 automatically changes the identification number of the common reference data included in the screen display data to be imported based on the trend graph ID change table 1041 shown in FIG. Further, the page number changing means 22 automatically changes the page number of the screen page data included in the screen display data to be imported based on the page number change table displayed on the screen tab 1021 shown in FIG. . Also, the device changing unit 23 automatically changes the device set in the screen display data to be imported based on the device change table 1050 shown in FIG. Further, the component image setting changing unit 24 follows the change by the identification number changing unit 21 with respect to the component image to which the common reference data to be changed by the identification number changing unit 21 is referenced. The setting of the component image is automatically changed so that is changed. Then, the import execution means 26 automatically changes the screen display data being edited and imports the screen display data to be imported. Accordingly, the user can easily avoid duplication of screen page data and common reference data, and can perform desired import such as allowing overwriting for a portion to be overwritten. Usability can be improved.

  In this embodiment, since the change by the identification number changing means 21 is permitted by clicking the “import execution” button 1055 shown in FIG. 23, the “import execution” button 1055 is allowed to change. This is an example of the receiving unit 25. By providing the “import execution” button 1055, it is possible to confirm to the user whether or not the import can be performed while avoiding duplication of the identification number of the common reference data. As a result, for example, when some users have changed their minds such as allowing duplication of some identification numbers (that is, overwriting some identification numbers), the return button is used to return to FIG. The trend graph ID change table 1041 to be shown and the device change table 1050 shown in FIG. 23 may be edited, so that an unintended import by the user can be prevented.

  As described above, when import is executed through the procedure of Step 1 → Step 2 → Step 3, duplication of trend graph IDs and devices is automatically avoided. The actual situation of avoidance will be specifically described with reference to FIGS. 24 to 30 are diagrams illustrating an example of a screen (GUI) displayed on the display unit 103 of the screen display data editing apparatus 100. FIG.

  First, as shown in FIG. 24, a trend graph of page number 100 and a trend graph of page number 101 are added to the workspace on the left side of the drawing editor screen after the import is completed (these are shown in FIG. 8). Does not exist in the drawing editor screen before the import is completed.) This indicates that the setting of the import target described with reference to FIG. 13 is reflected.

  Next, when the system setting tab 1001 is clicked in FIG. 24, the screen is switched to the screen shown in FIG. Focusing on the trend graph ID here, there are four icons, ID0 to ID3, on which pictures representing a line graph are displayed (in the workspace on the editing screen shown in FIG. ID2 and ID3 icons are simply square frames). This indicates that the import target setting described with reference to FIG. 14 is reflected.

  Next, in FIG. 25, when the trend graph ID0 in the workspace is clicked, the setting content of the trend graph ID0 is displayed in the edit area 1004 on the right side. Here, when the number of trends 1032 is noted, the number is two (as shown in FIG. 15, even when the screen display data being edited before the import is completed and the system setting tab 1001 is clicked, the number is two. ) This indicates that the setting contents of the trend graph ID0 are not overwritten and the user assets are not lost, as described with reference to FIG.

  Next, as shown in FIG. 26, when the trend graph ID2 in the workspace is clicked, the setting content of the trend graph ID2 is displayed in the edit area 1004 on the right side. Here, when the number of trends 1032 is noted, the number is 4 (as shown in FIG. 16, when the screen display data to be imported is opened and the system setting tab 1001 is clicked, the number is also 4). . This indicates that the setting content of the trend graph ID0 has been imported as the setting content of the trend graph ID2, as described with reference to FIG.

  Next, returning to FIG. 24, when a trend graph component image 1007 displayed in the editing area 1004 is double-clicked, a trend graph setting screen 1061 for the component image is displayed in a pop-up window. Here, a state in which the setting of the component image of the trend graph is changed by the component image setting changing unit 24 will be specifically described with reference to FIGS. 27 and 28. FIG. In FIG. 27, as shown in FIG. 16, after the screen display data “to be imported” is opened, a screen tab 1002 is clicked, and a trend graph component image (not shown) displayed in the editing area 1004 is doubled. A trend graph setting screen 1061 displayed when clicked is shown. On the other hand, FIG. 28 shows a trend graph setting screen 1061 displayed when the component image 1007 of the trend graph shown in FIG. 24 is double-clicked. That is, FIG. 27 is a setting screen for trend graph component images to be imported before the import is completed, and FIG. 28 is a trend graph component image incorporated in the screen display data being edited after the import is completed. It is a setting screen.

  27 and 28, the trend ID 1062 is “0” in FIG. 27, whereas the trend ID 1062 is “2” in FIG. Accordingly, the trend graph component image 1007 (FIG. 24) in which the trend graph ID 0 subject to change by the identification number changing means 21 is changed to the change by the identification number changing means 21 (trend graph ID 0 → trend graph ID 2). The setting of the component image of the trend graph is automatically changed so that the trend graph ID is changed following the change (FIG. 28). As described above, in the screen display data editing apparatus 100 according to the present embodiment, the component image setting changing unit 24 also changes the setting of the component image following the change of the identification number. There is no need to open the setting screen for each assigned component image and change the identification number one by one.

  In the present embodiment, the component image setting changing unit 24 also has a screen switching component image setting changing function. This function will be described more specifically with reference to FIG. 29, FIG. 30, and FIG. Below the editing area 1004 in FIG. 24, “unit monitor (outline)”, “unit monitor (detail)”, “error monitor”, “menu”,..., “Trend graph”, “graph description”, etc. Various component images are displayed. These are examples of screen switching component images in which page switching numbers for switching to other pages are set. That is, the screen switching component image indicates a component image in which a page switching number for switching to a screen with a page number different from the page number of the page on which the component image is arranged is set. For example, when “Graph Description” is clicked, the page can be switched to the graph description of page number 0101.

  In FIG. 29, as shown in FIG. 16, after the screen display data “to be imported” is opened, the screen tab 1002 is clicked, and the screen switching component image (not shown) of the graph explanation displayed in the editing area 1004 is displayed. A switch setting screen 1071 displayed when is double-clicked is shown. On the other hand, FIG. 30 shows a switch setting screen 1071 displayed when the screen switching component image 1006 of the graph explanation shown in FIG. 24 is double-clicked.

  As can be seen by comparing FIG. 29 and FIG. 30, in FIG. In FIG. 30, the page No. 1072 is 31. 1072 is 101. This is because the graph description of the page number 31 has been changed to the graph description of the page number 101 by the page number changing unit 22 as described with reference to FIG. As described above, the component image setting change unit 24 is configured to select the screen switching component arranged on the screen of the page number that is the target of change by the page number changing unit 22, that is, the screen switching component image 1006 described in the graph in this embodiment. The setting of the screen switching component image 1006 in the graph explanation is automatically changed so that the page switching number is changed following the change by the page number changing means 22 (page number 31 → page number 101). Then, the screen display data whose page switching number has been changed is imported by the import execution means 26 into the screen display data being edited. Thereby, the user can save the trouble of opening the setting screen individually for the imported screen switching part image and changing the page switching number.

[Processing operation]
FIG. 31 is a flowchart for explaining the processing operation in the screen display data editing apparatus 100 according to the present embodiment.

  As shown in FIG. 31, first, an edit target is accepted (step S1). Specifically, the edit target accepting unit 11 (FIG. 4) accepts designation of screen display data as an edit target from the user. For example, after the user activates the screen display data creation software in the screen display data editing apparatus 100, the user clicks “Open” (not shown) in the “File” menu in the upper left of FIG. When the is opened, the designation of screen display data to be edited is accepted.

  Next, the import target is accepted (step S2). Specifically, the import target accepting unit 12 (FIG. 4) accepts designation of screen display data as an import target from the user. For example, when the user clicks “Import” (not shown) in the “File” menu in the upper left of FIG. 8 and selects a file to be imported in the screen display data editing apparatus 100, the screen to be imported Accept specification of display data.

  Next, an identification number is acquired (step S3). Specifically, the identification number acquisition unit 13 acquires an identification number for identifying the common reference data from the screen display data being edited and the screen display data to be imported. For example, in step S2, the identification number is acquired at a timing immediately after the user clicks “import” (not shown). Further, import setting information is continuously created (step S4). In the present embodiment, a page number change table (see FIG. 10) of pages constituting screen page data, a trend graph ID change table 1041 (see FIG. 14), a device change table 1050 (see FIG. 21), etc. are created. It is created as import setting information by means 15. Thereafter, the import setting wizard shown in FIG. 9 is started (step S5).

  As described above, in the present embodiment, the processing of step S5 is performed after the processing of step S3 and step S4 is completed. That is, when the user visually recognizes the import setting wizard shown in FIG. 9, the import setting information has already been created. However, the present invention is not limited to this. For example, after the import setting wizard shown in FIG. 9 is started, the identification number can be acquired (step S3) and the import setting information can be created (step S4). That is, the process in step S5 may be performed between step S2 and step S3.

  Next, the import setting information is edited (step S6). More specifically, as described in detail with reference to FIGS. 9 to 23, the identification number edit accepting means 17 accepts editing from the user. If the import is OK (step S7: YES), the import is executed (step S8). For example, when the user clicks the “import execution” button 1055 shown in FIG. 23, the change permission is accepted by the change permission accepting means 25, and the identification number changing means 21, the page number changing means 22, the device changing means 23, and the part image are displayed. The setting changing unit 24 changes the settings of the identification number, page number, device, and component image, respectively. On the other hand, for example, when the user does not permit the execution of the import by clicking the “return” button shown in FIG. 23 (step S7: NO), the process returns to step S6. Alternatively, although not shown in FIG. 31, for example, when the “Cancel” button shown in FIG. 23 is clicked, the import setting wizard itself is closed and the import process is ended.

  As described above, according to the screen display data editing apparatus 100 according to the present embodiment, when new screen display data for displaying a screen on the display apparatus 200 is imported to the screen display data currently being edited, Work load can be reduced. In addition, the usability of the screen display data editing apparatus 100 can be improved.
