Description

  The present invention relates to a screen for a programmable display.

  Conventionally, as a system related to a programmable controller (PLC), a PLC controller main body, a programmable display connected to the controller main body to display control instructions and various sensor data, and any of these PLCs and programmable displays There is known a system including a program creation support device (a personal computer or the like; called a support device, a drawing editor device, or the like) that allows a user to create a program.

  A programmable display is generally a screen that displays the operating status of various devices to be controlled connected to the controller body, or an input operation screen (hereinafter referred to as an operation display screen) for giving control instructions to each device. It is known as an operation type display device that has a function of displaying input and receiving input.

  In general, the programmable display has a graphic display function, and the operation display screen includes various screen parts such as switches, graphs, and meters arranged on the screen, and graphical display of these various screen parts is possible. And an input operation using a touch panel or the like is accepted. The operation display screen is displayed based on so-called “screen data”.

  The operation display screen (the screen data) is arbitrarily created by the user / developer etc. (new creation or version upgrade etc.) in the program creation support device (drawing editor device etc.) and downloaded to the programmable display. . On the programmable display side, the downloaded screen data is stored, and on the basis of this screen data, the operation display screen is displayed or an input operation is accepted by a touch panel or the like.

Regarding the creation of a screen for the programmable display (the operation display screen), for example, the prior art described in Patent Document 1 is known.
The editor apparatus of patent document 1 can change the component image arrange | positioned by the user into an appropriate image component image according to the rule memorize | stored previously, or can change into an appropriate position.

  Here, there are not a few cases where a plurality of types of screens for the arbitrary programmable display (the operation display screen) are created. In this case, a plurality of operation display screens are switched and displayed in accordance with a user operation on the programmable display side.

FIG. 6 shows an example of screen switching on a conventional programmable display.
First, regarding the screen for the programmable display (operation display screen), as is well known, screen data including various component images such as switches, lamps, meters, etc., their functions, memory allocation information, etc. It is arbitrarily created by a developer or the like on the drawing editor device and downloaded to the programmable display. The programmable display stores screen data in its memory or the like. And a programmable display displays the said operation display screen on a display etc. using the memorize | stored screen data.

  When multiple types of operation display screens are used as described above, screen data corresponding to each operation display screen is created by a developer or the like on the editor device side, downloaded to a programmable display, and stored in a memory or the like Will be. Then, the programmable display unit displays the plurality of operation display screens so that the plurality of operation display screens are not displayed at the same time (only one operation display screen is displayed at a certain time), for example, by user operation. The display is switched according to.

  In the example illustrated in FIG. 6, the programmable display switches and displays three types of operation display screens of screen A, screen B, and screen C according to, for example, a user operation. In this case, as described above, the screen data of these three types of operation display screens are created in advance by the editor device and downloaded and stored in the programmable display. It should be noted that on the screens A, B, and C, various component images such as the above-described switches, lamps, meters, etc. are displayed. However, this is not illustrated, and only the display related to screen switching is illustrated and described. It shall be.

The switching display is performed by the screen switching button 101 arranged on each of the screens A, B, and C.
For example, FIG. 6A shows a state in which the screen A is displayed on the programmable display.

  In the illustrated example, a screen switching button 101 for switching to another screen (screen B, screen C) is displayed in the area on the right side of the screen A. Although not shown in the drawings as described above, for example, the various component images are displayed in the center or left area of the drawing.

  For example, when the user operates the “screen B” button among the screen switching buttons 101 on the screen A shown in the figure, the display screen is switched to a screen B as shown in FIG. Alternatively, for example, when the user operates the “screen C” button among the screen switching buttons 101 on the screen A, the display screen is switched to a screen C as shown in FIG.

  On the screens B and C, the above-described various component images (not shown) are displayed, and as shown in FIGS. 6B and 6C, a screen switching button 101 for switching to another screen is displayed. The For example, when the user operates the “return” button among the screen switching buttons 101 on the screen B shown in FIG. Alternatively, when the user operates the “screen C” button on the screen B shown in FIG. 6B, the display screen is switched to a screen C as shown in FIG. 6C, for example. Of course, on the contrary, the screen C may be switched to the screen B.

  In the illustrated example, characters such as “screen B” and “screen C” are displayed on each screen switching button 101. For example, in the case of an unfamiliar user, what screen is “screen B”? For the time being, the screen A was switched to the screen B, but there were cases where an extra operation such as switching to the screen C from there occurred.

  On the other hand, in order to enable an intuitive operation, for example, a thumbnail image (reduced image) of a switching destination screen is pasted on each screen switching button. In this case, for example, on the “screen B” button on the screen A shown in FIG. 6A, a thumbnail image of the screen B is displayed instead of the characters “screen B” shown in the figure.

JP 2010-128735 A

The prior art described above has the following problems.
It is also necessary to display a button for switching the screen (screen switching button 101 or the like) on the operation display screen of the programmable display on which various component images such as switches, lamps, and meters are displayed. In the example shown in FIG. 6, since there are only three types of operation display screens, this may not be a problem. However, in recent years, the number of operation display screens has increased. The number of screen switching buttons is also increasing. For this reason, problems such as difficulty in viewing the operation display screen (its various component images and the like) and difficulty in operation occur.

  Furthermore, when an operation display screen is added later, for example, it is necessary to add a screen switching button 101 for switching to the additional screen to all existing operation display screens. Usually, creation / modification / update of an operation display screen is performed manually by a user in a drawing editor device (also called a support device). For this reason, it takes time and effort for the user.

  In addition, when the thumbnail image is displayed on the screen switching button as described above, the user manually creates a thumbnail image of each operation display screen on the editor device, and changes the corresponding screen switching. Work such as pasting on the button is further required, which further increases the user's effort.

  An object of the present invention is to display a plurality of operation display screens for a programmable display without any problem even if the number of screen switching buttons is increased. The object is to provide a PLC system, an editor device thereof, a programmable display device, and the like that can reduce the labor of creation, and in particular, can reduce the labor of creation when a thumbnail image is displayed on a screen switching button.

  The PLC system of the present invention is a system having a programmable display and a drawing editor device, and the drawing editor device supports operation display screen creation support means for supporting creation of an arbitrary operation display screen for the programmable display device, A switch button list display screen for generating each screen switch button for displaying any one of the plurality of operation display screens and generating a switch button list display screen for displaying a list of each screen switch button Generating means; and a transmission means for transmitting and storing the plurality of operation display screens and the switching button list display screen to the programmable display side, and the programmable display displays the switching button list display screen. Screen display for switching the plurality of operation display screens by selecting any of the screen switching buttons. With a control means.

  In the PLC system, for example, a specific button for displaying the list display window is displayed on each operation display screen, and the screen display control means operates the specific button on the displayed operation display screen. Then, the switching button list display screen is displayed.

  In the PLC system, for example, a thumbnail image of a corresponding operation display screen is displayed on each screen switching button. Generation of the screen switching button including generation / setting of such thumbnail images is automatically performed by the switching button list display screen generation means.

  According to the PLC system of the present invention, its editor device, its programmable display, etc., when switching and displaying a plurality of operation display screens for a programmable display, it is possible to display without problems even if there are many screen switching buttons, Furthermore, it is possible to reduce the labor for creating the operation display screen and the screen switching button in the editor device, and in particular, it is possible to reduce the labor for creating the thumbnail image on the screen switching button.

It is a schematic block diagram of the PLC system of this example. It is an example of a display screen of the programmable display by this method. It is a figure which shows the example of a screen display and operation for preparation of the "thumbnail window" in a drawing editor apparatus. FIG. 10 is a processing flowchart of “thumbnail window” creation processing in the drawing editor device. It is a specific example of a model of switch data. An example of screen switching on a conventional programmable display is shown.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic configuration diagram of the PLC system of this example.
The illustrated PLC system (programmable controller system) includes a programmable display 10 and a drawing editor device 20. The programmable display device 10 and the drawing editor device 20 are connected to each other by some kind of communication line, and can communicate with each other. For example, the drawing editor device 20 downloads the operation display screen (its screen data) created on its own device to the programmable display device 10 via the communication line in the same manner as before.

  The programmable display 10 displays a screen component (such as a switch) for the user to give an arbitrary instruction to the controller body (not shown) of the PLC, and various status data collected by the controller body. The operation display screen or the like on which screen parts (lamp, numerical display unit, etc.) are arranged is displayed.

  Usually, a plurality of types of operation display screens are prepared. For example, the user switches to a desired operation display screen and is monitored by the various display components on the operation display screen being displayed at that time. / Control (operation of the switch by the user, visual recognition of numerical display, etc.) is performed.

Here, since the present technique relates to the switching of the operation display screen, illustration and description of the various display components such as the switch and the lamp are omitted.
Such an operation display screen is arbitrarily created in the drawing editor device 20 and downloaded to the programmable display 10. The drawing editor device 20 has a function for supporting a programmer or the like to create / change a desired operation display screen (screen data). Among the operation display screen creation / change operations, the arrangement of various display components such as the switch and the lamp is not directly related to the present method, and therefore will be omitted.

  Here, when multiple types of operation display screens are created as described above, as described above, in order to switch from a state in which an arbitrary operation display screen is displayed to another operation display screen display, each operation is displayed. The screen switching button is displayed on the display screen. A plurality of the screen switching buttons are basically displayed for each operation display screen, and this causes a problem when a large number of screen switching buttons are displayed as described above.

  On the other hand, in this method, as shown later in FIG. 2 and the like, only one specific button is displayed for each operation display screen. Only one is displayed regardless of the number of operation display screens. When any one specific button is operated on any operation display screen, a “switch button list display window” 40 described later is displayed. Details will be described later.

  However, in this example, there is shown an example in which there is only one specific button (in other words, only one “switch button list display window” 40). However, the present invention is not limited to this example. There may be a plurality of the specific buttons (the “switching button list display window” 40 is also displayed in accordance with each specific button, so that there are a plurality of specific buttons). For example, when there are two “switch button list display windows” 40, there are also two specific buttons in accordance with this. In this case, each screen switching button is arranged and displayed in one of the two “switching button list display windows” 40. In particular, when there are a large number of screen switching buttons, a single “switching button list display window” 40 will cause a large number of screen switching buttons to be arranged and displayed on the window, making operation difficult. In some cases, it may be desirable to distribute and display in a plurality of windows.

However, in this example, it is illustrated and described using an example in which there is only one specific button (there is only one “switch button list display window” 40).
The programmable display 10 has a control unit, a communication interface, a touch panel, a display, etc., not particularly shown. The control unit includes a CPU, a memory, various controllers, and the like. The CPU or the like displays the operation display screen on the display based on screen data or the like stored in the memory. Of course, a predetermined application program or the like for realizing this processing is also stored in the memory in advance, and the display of the operation display screen or the like is realized by the CPU reading and executing this program. Of course, as described above, the user operation items (switches, buttons, etc.) displayed on the operation display screen can be arbitrarily operated and input by the user. The screen data and the “switch button list display window” 40 to be described later are arbitrarily created by the drawing editor device 20 and downloaded to the programmable display device 10.

  In other words, it can be said that the programmable display 10 has the illustrated screen display control unit 11. The screen display control unit 11 displays the operation display screen on the display based on the screen data stored in the memory, and executes input reception and input processing on the operation display screen. is there. Although this operation itself may be an existing technology, this method has a point different from the conventional screen data, and a “switching button list display window” 40 is added, so that the user operability is improved as compared with the conventional method. It will be a thing. Details will be described later.

  As is well known, the drawing editor device 20 is realized by a personal computer or the like, and includes, for example, a CPU, a hard disk, a memory, a user operation unit (keyboard, mouse, etc.), a display, a communication interface, and the like. The hard disk or the like stores a drawing editor program or the like. When the CPU reads out and executes this program, a creation support screen (not shown) for supporting creation of the operation display screen is displayed, and the user creates an arbitrary operation display screen. This function (the function of the “screen data creation support unit” 21 shown in the figure) itself is substantially the same as the conventional one. However, in this method, a function for automatically creating a “screen switching button display window” and the like (to be described later) is shown. (Switching button list display window generation unit 22).

  The “switch button list display window generation unit” 22 has a function of automatically generating a “switch button list display window” 40, and in particular has a function of automatically generating a “thumbnail window” to be described later. . Details will be described later.

FIG. 2 is a screen display example of the programmable display of this example.
Here, any one of the plurality of operation display screens is displayed, and the illustrated list window display switch 30 as the specific button on the operation display screen is operated. , “Switching button list display window” 40 is displayed.

  Although not specifically shown, the above list window display switch 30 is similarly displayed on another operation display screen, and when this switch 30 is operated, a “switch button list display window” 40 is displayed. It has become.

  For example, there is one “switching button list display window” 40, and when one specific switch 30 is operated on any of the operation display screens, the one “switching button list display window” is displayed. "40" is shown as an example, but as described above, the present invention is not limited to this example.

  For example, there may be a plurality of “switch button list display windows” 40. In this case, for example, a plurality of the switches 30 are arranged on each operation display screen, and a corresponding “switch button list display window” is displayed when any switch 30 is operated. Also good. Even in this case, the number of switches 30 may be smaller than the number of operation display screens.

  On the “switch button list display window” 40, for example, a screen switch 41 shown in the figure corresponding to a conventional screen switch button is displayed as a list. Assuming that there is one “switch button list display window” 40, “the number of screen changeover switches 41 = the number of operation display screens”. When an arbitrary screen changeover switch 41 is operated, a corresponding screen (operation display screen) is displayed. Of course, in this case, each switch 41 is associated with each operation display screen in a one-to-one correspondence.

  As described above, the user can switch to the desired operation display screen by operating the desired screen changeover switch 41 on the “switch button list display window” 40.

  In this manner, by preparing a dedicated window 40 for switching the operation display screen, it is only necessary to arrange a specific button for calling and displaying the window 40 on each operation display screen. become.

  Accordingly, even if the number of operation display screens increases, for example, only one button for switching the operation display screens is required for each operation display screen. ) Becomes difficult to see ”and“ is difficult to operate ”. Furthermore, even when a new operation display screen is added later, there is no need to change the existing operation display screen. Therefore, the trouble of the user on the drawing editor device 20 side can be reduced.

  Further, in the “switch button list display window” 40, a thumbnail screen of the operation display screen of the switch destination may be displayed on each screen switch 41. Here, such a “switch button list display window” 40 is referred to as a “thumbnail window”.

  In this example, the drawing editor device 20 has a function of automatically creating / updating a “switch button list display window” 40 when creating a screen data group or adding new screen data thereafter. . This reduces the user's trouble. In particular, in the case of the “thumbnail window”, as described above, an arbitrary button has been conventionally displayed as a thumbnail, but for this purpose, a developer or the like manually creates a thumbnail screen or adds a button to the button. Because it was pasting, it was very time-consuming. In this example, since it can be automated without such a labor, the labor of the user can be greatly reduced.

FIG. 3 is a diagram showing a screen display / operation example for creating the “switching button list display window” (particularly “thumbnail window”) in the drawing editor device 20.
For example, taking the case of creating a “thumbnail window” as an example, a thumbnail window registration screen 60 shown in the figure is displayed on the display of the drawing editor device 20, for example. Further, the thumbnail window screen 50 shown in the figure may be displayed. The processing described later according to these screen displays and operations on the screen is executed by, for example, the “switch button list display window generation unit” 22.

  The thumbnail window screen 50 is not arranged in the initial state, but when a user operation described below is performed, for example, two screen changeover switches 51 are arranged as illustrated. Note that this may be considered as being created, and there may be a case where the third and subsequent screen changeover switches 51 are arranged.

  The thumbnail window screen 50 may be regarded as the same as the “switch button list display window” 40 except that the thumbnail window screen 50 is being created by the drawing editor device 20. Therefore, the screen changeover switch 51 may be regarded as corresponding to the screen changeover switch 41. However, in this example, a thumbnail screen of the corresponding screen is displayed on the screen changeover switch 51 (41).

The thumbnail window registration screen 60 includes a registered screen display area 61, a screen list display area 62, a registration button 63, a delete button 64, and the like.
Here, the thumbnail window registration screen 60 shown in the figure may also be regarded as indicating the state of the above creation. That is, two screens are already registered in the registered screen display area 61, and as a result, the two screen changeover switches 51 are arranged on the thumbnail window screen 50 as described above. .

  If an initial state (not shown) is assumed, the registered screen display area 61 is blank in the initial state, while the screen list display area 62 includes “screen 0000”, “screen 0001”, and “screen 0002”. Five screen names “screen 0003” and “screen 0004” are displayed.

  Here, for example, when a user designates an arbitrary programmable display on another screen (not shown), file names of screen data of all screens (operation display screens) created for this programmable display (screen name) Are displayed in a list in the screen list display area 62. Of course, in the drawing editor device 20, an operation display screen (identification information thereof; for example, a screen number or a screen name) corresponding to each programmable display is registered in advance. This is registered when the screen data creation support unit 21 creates screen data. In the illustrated example, both the screen No. and the screen name are displayed (for example, screen No. = “0000”, screen name = “screen 0000”, etc.), but the present invention is not limited to this example. For simplicity, only the screen name is mentioned in the following description.

  The user selects a desired screen (operation display screen) by selecting a desired screen name from the list display, and then operates the registration button 63 shown in the figure. Accordingly, the “switch button list display window generation unit” 22 generates a screen switch 51 corresponding to the selected screen and arranges it on the thumbnail window screen 50, for example, by executing the processing of FIG. To do. Then, the selected screen name is moved from the screen list display area 62 to the registered screen display area 61.

  In the example shown in the figure, for example, when “screen 0000” is first selected on the screen list display area 62 and the registration button 63 is operated, a screen switch corresponding to “screen 0000” is displayed on the thumbnail window screen 50. 51 is generated and arranged. Furthermore, “screen 0000” is deleted from the screen list display area 62 and displayed in the registered screen display area 61. Subsequently, when “screen 0003” is selected on the screen list display area 62 and the registration button 63 is operated, the screen changeover switch 51 corresponding to “screen 0003” is generated and arranged on the thumbnail window screen 50. Is done. Further, the “screen 0003” is deleted from the screen list display area 62 and displayed in the registered screen display area 61.

  In the case of the processing example of FIG. 4 to be described later, for example, a thumbnail image of the operation display screen of “screen 0000” is displayed on the above-described “screen changeover switch 51 corresponding to“ screen 0000 ””. It becomes.

  Note that the delete button 64 is used to cancel the registration of the registered operation display screen. That is, when the user selects a desired screen name on the registered screen display area 61 and operates the delete button 64, the selected screen name moves to the screen list display area 62. Further, the clean changeover switch 51 corresponding to the selected screen name is deleted from the thumbnail window screen 50.

FIG. 4 is a process flowchart of the “thumbnail window” creation process in such a drawing editor apparatus 20.
In FIG. 4, for example, when the user designates an arbitrary operation display screen as a processing target on the thumbnail window registration screen 60 as described above, the designated operation display screen is drawn on the memory (using the screen data). (Step S11). Then, the drawing data is converted into a bitmap (step S12). Then, a thumbnail image (referred to as a thumbnail bitmap) is generated by reducing the bitmap data so as to have a preset designated size (step S13).

  Then, a screen changeover switch 51 for switching to the operation display screen to be processed is arranged at a predetermined position on the “thumbnail window” 50 by the processing of the following steps S14 to S18. Paste the generated thumbnail bitmap into.

  First, for example, a switch data template as shown in FIG. 5 is acquired from a predetermined storage area. Then, by storing arbitrary data in the switch data template, new switch data is generated. This is an existing technology that has been performed in the past, and will be briefly described below.

  FIG. 5 shows only a part of each item of the switch data. First, the first “recognition flag” is a graphic (straight line, curve, circle, rectangle, etc.) or a part (switch, lamp). , Various screen components such as a meter) are stored. When the “recognition flag” is a part, the next “switch ITEM” stores identification information indicating any one of the switch, lamp, meter, and the like. In the case of switch data, of course, the “recognition flag” is part information, and the “switch ITEM” is switch identification information. For example, these may be set in advance in the switch data template.

  Furthermore, there are various functions as a switch, and any function is stored in the “function TYPE” shown in the figure. Since the function of the screen changeover switch 51 (41) is “screen changeover function”, “screen changeover function” is stored in “function TYPE”. Further, in the illustrated “function data”, when “function TYPE” is “screen switching function”, identification information (screen No., etc.) of the screen to be switched to is stored.

  Further, when displaying an arbitrary character or image on the switch 51, a certain character string or image data file name or the like is set in the “character string data” or “image data” shown in the figure. In the above conventional description, for example, when “screen B” is displayed on the switch, “screen B” is registered in the “character string data” field. In addition, when displaying an arbitrary thumbnail image on the switch in the above prior art, the file name of the thumbnail image is registered in the “image data” field. Of course, when the screen data is downloaded to the programmable display, the thumbnail image file is also downloaded and stored together.

  It is assumed that the switch size is determined in advance. It is assumed that the default size (width and height) of the “thumbnail window” is also determined in advance. Of course, the size information is stored in advance in a memory (not shown) or the like.

  Here, if the description is made on the assumption of the above example, first, based on the size of the “thumbnail window” (further, based on the arrangement position information of other switches already arranged), the new switch 51 is obtained (step S14). This is merely to obtain a space that can be arranged, and is the same as existing general processing, and will not be described in detail, but an example will be briefly described below.

  For example, the initial arrangement coordinates (for example, the upper left corner) on the “thumbnail window” are registered in advance, and the screen corresponding to the screen first selected on the screen list display area 62 (screen 0000 in the above example). The arrangement position of the changeover switch 51 is determined by these initial arrangement coordinates. Next, the arrangement position of the switch 51 corresponding to the selected screen is determined whether it can be arranged on the right side of the switch 51 already arranged immediately before it, and if it can be arranged, it is arranged on the right side. If it is not possible, the left corner below one line is determined as the placement position.

  The determination as to whether or not it can be arranged on the right side is, for example, “(number of switches 51 already arranged in the row + 1) × (X direction size of switch 51)” is the X direction size of the “thumbnail window”. If it is less, it is determined that arrangement is possible. Of course, these X-direction sizes (Y-direction sizes) are arbitrarily set and registered in advance.

  The new switch is newly placed at the placement position obtained in step S14 (step S15). For example, the arrangement position obtained in step S14, the previously registered switch size, and the like are stored in the item field of the arrangement information (start XY coordinates and XY size) shown in the switch data model.

  Subsequently, the “screen switching function” is set in the “function TYPE” field in the switch data template (step S16), and the identification information (screen number etc.) of the screen data to be processed is entered in the “function data” field. ) "Is stored (step S17).

Finally, the file name of the thumbnail bitmap generated in step S13 is registered in the “image data” field in the switch data template (step S18).
Conventionally, information on a screen (including a thumbnail window and the like) includes information on various items displayed on the screen, and the switch data is generated and created as part of this information. It is to be registered.

  The processing related to the predetermined target screen data is completed as described above. However, if there are other processing targets, the user is allowed to specify them, and the processing of steps S11 to S18 is also performed for this. When the process is executed, this process ends.

  The list window display switch 30 on each operation display screen is arbitrarily created by the user on the drawing editor device 20 side. That is, when the user (developer, etc.) on the drawing editor device 20 creates a desired operation display screen (its screen data) by the support function of the screen data creation support unit 21, the list window display switch 30 is used. Also create. Conventionally, the user has created the screen switching button 101, and the list window display switch 30 can be created by substantially the same operation. The difference from the screen switching button 101 is that the screen to be switched and displayed is fixed (switch button list display window 40), and the identification information of the “switch button list display window” 40 is included in the “function data”. Will be stored.

  As described above, according to the PLC system of the present example, the editor device 20 thereof, the programmable display device 10 and the like, in the case of switching and displaying a plurality of operation display screens for the programmable display device, the screen switching buttons are increased. Can be displayed without problems, and problems such as “it becomes difficult to see the operation display screen (its various component images)” and “difficult to operate” can be solved. Furthermore, it is possible to reduce the time and labor of creating the operation display screen and the screen switching button in the editor device 20, and particularly when creating a thumbnail image on the screen switching button.
