Description

  The present invention relates to a programmable display, a drawing editor device, and a display / control system comprising these devices.

  Conventionally, in a control system (for example, a programmable controller (PLC)), a user (operator, etc.) inputs an arbitrary instruction (for example, switch ON / OFF, etc.), and various statuses of controlled devices for monitoring by the operator Programmable displays that display data and the like are used.

  On the display of the programmable display, an operation / display screen for performing the instruction input and displaying the state is displayed. Various items (various parts such as switches and buttons) are usually displayed on the operation / display screen. Also, the input method by the user is often a touch panel installed on the display. The user gives an instruction by pressing the display position of an arbitrary item.

  A conventional programmable display is a user interface mainly operated by a switch. Regarding the switch operation, the operability is widened by changing the operation timing such as once pressing, twice pressing, and long pressing in the same switch region.

FIG. 10 is a diagram for explaining the related art relating to the operation / display screen of the programmable display.
Conventionally, first, the user creates arbitrary operation / display screen data (hereinafter may be simply referred to as screen data) in the drawing editor apparatus 110 in which the drawing software 111 is installed. As described above, various items (parts) are arranged at arbitrary positions. However, for the sake of simplicity, only two items of “number” and “switch” are arranged. The screen data shall be shown.

  The created screen data is downloaded from the drawing editor device 110 to the programmable display device 100. The programmable display 100 stores this screen data in a nonvolatile memory such as the flash ROM 101, for example. Thereafter, the programmable display 100 displays an operation / display screen on a display or the like based on the screen data stored in the flash ROM 101.

  This is to display each item constituting the screen data at a predetermined position on the display. That is, each item includes, for example, image data indicating the shape of any switch in the case of the above-mentioned “switch”. Attached information such as location information is also included. These are all generated when the screen data is created on the drawing editor device 110 side. Unique No. Is a unique unique identification number assigned to an item each time it is placed on the screen. The position information is, for example, XY coordinates indicating the arrangement position of the item on the screen. The image of each item is displayed at the position indicated by the position information.

  Although not shown, a PLC (programmable controller) main body (not shown) is connected to the programmable display 100. For example, when the user operates the “switch”, a command corresponding to the PLC is sent to the PLC. Will be sent to. In addition, information indicating some state on the PLC side is displayed on the item “numerical value”.

Moreover, the prior art described in Patent Document 1 is known.
In the invention of Patent Document 1, with respect to the information display operation device, for example, as shown in FIGS. 1, 11, 14, etc., rearrangement keys RK corresponding to each key K are displayed on the left and right sides of the screen. .

JP-A-9-265376

  In some cases, after the screen data is downloaded to the programmable display device 100 as described above, it is desired to change the contents of the screen data. For example, there is a case where it is desired to change the arrangement of item images. This is because, for example, the creator of the screen data intends to perform the arrangement that seems to be convenient (arrangement of each item image), but when the operation is actually performed with the programmable display 100, the usability is increased. The case where a bad point is found etc. can be considered. Alternatively, when a person other than the creator of the screen data operates the programmable display device 100, it may feel unusable. In particular, when a plurality of persons alternately operate the programmable display device 100, there is a demand for customization so that each user has a user-friendly arrangement.

  Conventionally, when it is desired to change the contents of the screen data (particularly the arrangement of items) as described above, it is necessary to recreate the screen data on the drawing editor device 110 side and download it again to the programmable display device 100. There was, and it took time and effort. In particular, when it is desired to customize for each user, it is very time-consuming.

  On the other hand, in the above-mentioned Patent Document 1, each key can be rearranged with respect to the information display operation device, but this is displayed in a predetermined area (left and right of the screen) and can be placed at any position. It cannot be freely rearranged. Furthermore, even if it is called rearrangement, the key does not move, and the original key remains as it is. For this reason, if all the keys are rearranged, the number of keys is doubled (all the keys are two each). For this reason, the screen is filled with keys, which is rather difficult to use.

  The problem of the present invention is that the arrangement of the item image on the screen can be changed on the programmable display side, the display screen can be customized without taking time, and the change is temporary and complete change. It is providing the programmable display etc. which can select.

  The programmable display of the present invention includes a first storage means for storing screen data having position information of each of one or more items, a mode specifying means for performing at least one of normal mode and edit mode designation, In the edit mode, the item can be moved by a predetermined operation determined in advance, and when an arbitrary item is moved to an arbitrary position by the predetermined operation, the position is set as the rearrangement position. Item rearrangement means for storing information in the second storage means, and means for displaying the screen for the programmable display by displaying each item, the position information being stored in the second storage means Items are arranged and displayed based on the position information stored in the second storage means, and the position information is displayed in the second storage means. Respect 憶 that are not items and a display control means for arranging and displaying based on the position information stored in said first storage means.

  According to the programmable display and the like of the present invention, the arrangement of the item image on the screen can be changed on the programmable display side, the display screen can be customized without taking time, and further temporary You can choose between changes and complete changes.

Embodiments of the present invention will be described below with reference to the drawings.
In FIG. 1, the schematic block diagram of the display / control system (PLC system containing a programmable display etc.) of this example is shown.

  In FIG. 1, a display / control system includes a programmable display 1, a programmable logic controller (hereinafter referred to as "PLC") main body, a connection device 4 that is a control target device (motor, temperature controller, etc.), and a drawing editor device. 5

  The programmable display device 1 has a plurality of communication interfaces 2, and each communication line 3 is connected to each communication interface 2. The programmable display device 1 can communicate with the connection device 4 and the drawing editor device 5 via each communication line 3. For example, the programmable display device 1 is connected to the various connection devices 4 via the communication interface 2 and the communication line 3, thereby notifying instructions via the communication line 3 etc. according to the protocol unique to each connection device. The control of the connection device 4 and the state of the connection device 4 can be displayed.

  As already described in the prior art, an operation / display screen for causing the user to perform such operations (switch operation, etc.) for controlling the connected device 4 and for displaying the status is displayed on the display of the programmable display 1. Is done. Various items (switches, lamps, graphs, numerical values, etc.) are displayed on the operation / display screen. The user touches the display position of a desired item and executes a function assigned in advance to the item, thereby controlling the connected device 4 and the like.

  As described in the prior art, the data relating to each item includes, for example, image data indicating switches, lamps, etc. In addition, position information and the like are included (and an image based on image data is displayed at the position indicated by the position information), and a program for realizing the above functions is also included.

  In addition, the connection device 4 which is a PLC main body or a device to be controlled (motor, temperature controller, etc.) includes a general-purpose work memory, a memory for identifying each control information, etc. by a device name and an address, and a function for controlling them. It is common to be realized by.

  In addition, control object apparatuses (a motor, a temperature controller, etc.) are not necessarily connected to the programmable display 1 among the connection apparatuses 4, These may be connected to the said PLC main body. In this case, a command or the like corresponding to the user operation is transmitted to the PLC main body, and the PLC main body controls the control target device according to the command or the like.

  Further, the drawing editor device 5 has drawing software that realizes a processing function for arbitrarily creating a screen (operation / display screen) for the programmable display (including its screen parts (items)) by the upper user.

  Note that the schematic configuration itself described above may be the same as that of the prior art. In this example, regarding the function of the programmable display device 1, there is a part different from the conventional one. The drawing editor device 5 of this example is different from the conventional one in that it has a function of updating the screen data stored by the screen data on the programmable display 1 side, but the rest is almost the same as the conventional one. It may be regarded as substantially the same.

  FIG. 2 is a hardware configuration diagram of the programmable display 1. Note that the hardware configuration itself may be the same as the conventional one. The drawing editor device 5 may be a general general-purpose personal computer in terms of hardware, and is not illustrated or described here. What is different from the prior art is the functions of the programmable display 1 and the drawing editor device 5, particularly the functions of the programmable display 1. Details will be described later, and here, the configuration of FIG. 2 will be briefly described.

In FIG. 2, the programmable display device 1 includes a control unit 10, the communication interface 2, a touch panel 18 and a display 19.
The control unit 10 includes a graphic controller 11, a flash ROM 12, a RAM 13, a communication controller 14, a CPU 15, a touch panel controller 16, and the like, which are connected to an internal bus 17. The flash ROM 12 is a non-volatile memory, and the RAM 13 is a volatile memory.

  The graphic controller 11 is a dedicated module that is connected to the display 19 and displays an arbitrary screen or the like on the display 19. The graphic controller 11 is controlled by the CPU 15 to display, for example, the operation / display screen on the display 19. This operation / display screen is displayed based on the screen data.

  In the following description, it is assumed that the CPU 15 performs display control of, for example, the operation / display screen on the display 19 and does not describe the graphic controller 11 one by one. Thus, in the processing of flowcharts and the like described later, the CPU 15 will be described as performing processing such as screen display / editing, but although not described one by one, this includes that realized by controlling the graphic controller 11. To do.

  Various programs and screen data are stored in the flash ROM 12. The flash ROM 12 is a readable / writable ROM, for example, and may be called a flash memory.

  Arbitrary various data are memorize | stored in RAM13. Conventionally, for example, device status data collected from each connected device 4 is stored, but in this example, a “position change list 24” described later is further stored.

  Here, conventionally, the CPU 15 displays the operation / display screen based on the screen data (each item information thereof) stored in the flash ROM 12. However, the CPU 15 of this example uses the operation / display screen based on the “position change list 24” stored in the RAM 13 as well as the screen data stored in the flash ROM 12 (each item information thereof). Is displayed.

  Basically, the “position change list 24” is displayed with priority. That is, first, when one or more item information is registered with reference to the “position change list 24”, all items registered in the “position change list 24” are displayed on the display 19. (Note that the “position change list 24” may include only the unique number and the position information registered. In this case, the item image is acquired from the screen data 22 and displayed. become).

  Subsequently, by referring to the screen data 22 of the flash ROM 12, all items that are not registered in the “position change list 24” are extracted from the items constituting the screen data. Then, all the extracted items are displayed on the display 19. This display process and the “position change list 24” will be described in detail later.

  The communication controller 14 is connected to the communication interface 2 and realizes communication with the connection device 4 and the drawing editor device 5 via the communication interface 2 and the communication line 3 described above. The CPU 15 communicates with the connection device 4 and the drawing editor device 5 via the communication controller 14, the communication interface 2, and the communication line 3. As in the case of the graphic controller 11, in the following description, the communication controller 14, the communication interface 2, and the communication line 3 will not be described one by one.

  The touch panel controller 16 is connected to the touch panel 18 and detects a user operation (such as a pressed position coordinate) on the touch panel 18. The CPU 15 recognizes the operation content by the user based on the detection result by the touch panel controller 16. As in the case of the graphic controller 11, the touch panel controller 16 will not be described in the following description.

  The CPU 15 is a central processing unit that controls the entire control unit 10. The CPU 15 realizes various functions to be described later, for example, by reading and executing the various programs stored in the flash ROM 12. As described above, this realizes, for example, the processing of the flowchart described later.

  As for the drawing editor device 5, the general-purpose personal computer includes, for example, a CPU, a hard disk, a memory, a user operation unit (keyboard, a mouse, etc.), a display, a communication interface, and the like as is well known. The hard disk or the like stores a drawing editor 31 (program) to be described later. The CPU realizes various functions to be described later by reading and executing this program.

FIG. 3 is a software configuration diagram of the display / control system.
In the illustrated example, first, the programmable display device 1 includes a main body program 21, screen data 22, a communication program 23, a position change list 24, and the like. The main body program 21, screen data 22, and communication program 23 are stored in the flash ROM 12, for example. The position change list 24 is stored in the RAM 13.

  The CPU 15 implements various functions to be described later by reading and executing the programs 21, 23, etc. (further using the screen data 22 and the position change list 24). Although this will be described in detail later, this method has at least a “normal operation” mode and a “screen editing” mode described later.

  In the “normal operation” mode, each item is displayed according to the screen data 22 and the “position change list 24”. That is, in the past, each item was displayed according to the screen data 22, but as described above, this method further refers to the “position change list 24”. The registered item is displayed based on the position information in the “position change list 24”. It should be noted that the “normal operation” mode is set at the time of startup, and thereafter, the “normal operation” mode is maintained unless there is a mode switching operation.

In the “normal operation” mode, screen display (display of each item) is only performed, and the arrangement (display position) of the item cannot be changed.
When the user wants to change the display position of the item, the user switches to the “screen editing” mode. As will be described later in detail, in the “screen editing” mode, the user can move the display position of any item on the screen to a desired position. For example, the user can move (rearrange) an arbitrary item by performing a drag-and-drop operation.

  Here, providing a function that enables arbitrary movement of an arbitrary item by a drag-and-drop operation in a programmable display device has already been proposed in, for example, a prior application (Japanese Patent Application Laid-Open No. 2011-90650). . Therefore, although such a function itself is not specifically described here, the point different from the prior application is that the position where the drop operation is performed is recognized as a movement destination (rearrangement) position, and the movement destination position (XY coordinates, etc.) ) Is registered in the “position change list 24”. In the “screen editing” mode, each item is displayed according to the screen data 22 and the “position change list 24” and with priority on the “position change list 24”, as in the “normal operation” mode. Details will be described later.

  Here, as described above, the “position change list 24” is stored in the RAM 13, which is a volatile memory, and is erased when the power of the programmable display 1 is turned off. Further, although not particularly illustrated, a command button for deleting the “position change list 24” may be provided on the screen, and the “position change list 24” may be deleted when the user operates this button. . In any case, for example, when it is desired to customize each user so as to have a desired arrangement, each user can change the original arrangement (the arrangement of the screen data 22) before starting his own work. The desired item rearrangement may be performed based on the screen data 22.

  On the other hand, there is a case where it is desired to change the screen data 22 itself. In this case, after performing the desired rearrangement in the “screen editing” mode, the user performs an operation for instructing “edit saving” at any time (but before turning off the power). In response to the “edit / save” instruction, a later-described save process is performed, whereby the contents of the screen data 22 are updated to, for example, the contents of the current display screen.

  The screen data 22 is downloaded from the drawing editor device 5 to the programmable display device 1 at any time and stored in the flash ROM 12 (if there is old screen data 22, it is updated to the downloaded new screen data 22). ). This may be substantially the same as that of the prior art. However, in this method, for example, when the user instructs “edit and save”, the content of the screen data 22 is updated based on the position change list 24. The Details will be described later.

  The main body program 21 and the communication program 23 are basically stored in the flash ROM 12 in advance (for example, when the programmable display device 1 is manufactured in the factory), but are downloaded from the drawing editor device 5. Also good.

  The drawing editor device 5 includes a drawing editor 31 that is an application program for creating arbitrary screen data 22 by a user or the like. The drawing editor 31 is installed in the drawing editor apparatus 5 in advance, and is stored in, for example, the hard disk (not shown).

Further, a screen data file 32, a communication program file 33, and the like may be stored in a hard disk (not shown).
An arbitrary screen data file 32 created using the drawing editor 31 is downloaded to the programmable display 1 as described above and stored as the screen data 22 shown in the figure. The screen data file 32 is left on the drawing editor device 5 side. If the screen data 22 on the programmable display device 1 side is lost or damaged for some reason, it is downloaded to the programmable display device 1 again.

  The download process and the update of the screen data 22 on the programmable display 1 side by the download process may be regarded as substantially the same as the conventional one. However, in the present technique, on the contrary, the drawing editor device from the programmable display 1 side. The screen data file 32 may be updated by uploading the screen data 22 to 5. This upload is basically performed after an update described later (update reflecting rearrangement) is performed on the screen data 22. In this case, the contents of the screen data file 32 are updated to the contents of the uploaded screen data 22. Details will be described later.

  The display function of the programmable display 1 and the control function of the connected device 4 are communication corresponding to the above-mentioned main body program 21 and the main body program 21, which are programs related to basic functions such as display control, and a unique protocol for each of the various connection models 4. The communication program 23 is a program related to control. The main body program 21 and the like are stored in advance in the flash ROM 12 and the like, for example.

Hereinafter, the operation of the programmable display 1 will be described with reference to FIGS.
First, FIG. 4 shows an example of data stored in the flash ROM 12 and the RAM 13 and an example of a screen displayed on the display 19 in the programmable display 1.

  The flash ROM 12 stores the screen data 22 and the like basically in the same manner as the conventional flash ROM 101. Here, as in the above-described conventional example, screen data on which only two items of “numerical value” and “switch” are arranged is shown. As shown in the figure, this is not limited to the image data for each item. Attached information such as location information is also included. Of course, the program etc. which implement | achieve the function (for example, function as a switch etc.) of each item are also contained.

  In this method, the function of each item itself cannot be changed on the programmable display side (what can be changed is only the arrangement of each item on the screen). Therefore, even in the case of an item displayed according to the position change list 24, for example, when the item is operated in the “normal operation” mode, the function of the item is executed using the program included in the screen data 22. Become.

The image data is displayed at the position indicated by the position information. For example, it is displayed like an operation / display screen 40 on the display 19 shown in the figure.
Here, in this method, not only the item image but also a predetermined button set in advance is displayed on the operation / display screen 40. For example, a “screen edit” button 41, an “edit save” button 42, and the like shown in the figure are displayed.

  Here, the programmable display 1 of this example is in a “normal operation” mode at the time of startup, for example. In this “normal operation” mode, display control is basically performed in the same manner as in the past (thus, in the “normal operation” mode, the position of the item cannot be moved, of course), but as described above The display control is performed with priority on the position change list 24, which is different from the conventional one. In other words, based on the position information of the screen data 22 stored in the flash ROM 12 and the position information of the position change list 24 stored in the RAM 13, the position information of the position change list 24 is given priority. Is arranged and displayed at the position indicated by the position information. Such display with priority on the position change list 24 may be regarded as substantially the same in the “screen editing” mode.

Regardless of the current mode, the “edit screen” button 41, “edit save” button 42, etc. are displayed at predetermined positions on the screen.
The user of the programmable display 1 operates (presses) the “screen edit” button 41 when he / she wants to change the layout by referring to the screen display in the “normal operation” mode. Thus, when shifting to the “screen editing” mode, it is possible to arbitrarily move any item on the screen to the destination. The various processing operations of the programmable display 1 in the following description are basically realized by the CPU 15 executing a predetermined application program (the main body program 21 and the like).

Here, as an operation method (predetermined operation) for moving an item on the screen, a “drag and drop” operation is used in this example, but the present invention is not limited to this example.
In the “screen editing” mode, the programmable display device 1 moves the user to an arbitrary item image on the screen (the above “drag and drop” operation or the like; for example, when the user drags an arbitrary item, When the “drag state” described in the application is entered, and the process described in the previous application is performed during the “drag state” and the item is moved)), the identification information of the item to be moved (Unique No., etc.) is recognized, and position information (X coordinate, Y coordinate) of the movement destination is detected. And the unique number of the rearranged item. And the position information of the rearrangement destination are added / registered in the position change list 24 on the RAM 13.

  However, this does not change the contents of the screen data 22 of the flash ROM 12. Regarding the items that have been rearranged, the flash ROM 12 stores the identification information (unique No., etc.), the position information (X coordinate, Y coordinate), the item image, and the like as before. Note that the position information stored in the flash ROM 12 may be referred to as default position information. The position information stored in the RAM 13 may be referred to as rearrangement position information.

  In this method, regardless of what the current mode is, the position change list 24 is preferentially displayed and controlled with respect to the display of items. That is, first, with reference to the position change list 24, all items registered in the position change list 24 are displayed on the screen based on the rearrangement position information. Subsequently, based on the screen data 22 stored in the flash ROM 12, an item that has not been registered in the position change list 24 (its unique number is other than the unique number registered in the position change list 24. Each item is displayed on the screen based on the default position information. Of course, the identification of each item is a unique number. And so on.

  Thus, in the “screen editing” mode, for example, when only the item “switch” is moved and rearranged as shown in FIG. 4, the “normal operation” mode is subsequently set even during the “screen editing” mode. Also when the item is returned, the item “switch” is displayed at the movement destination (relocation position), while the item “numerical value” is displayed at the default position.

  Thereafter, when the power of the programmable display 1 is turned off, all the information stored in the position change list 24 on the RAM 13 is deleted, so that all items are again based on the screen data 22 of the flash ROM 12 after restarting. It will be displayed in the layout (default layout).

In this way, for example, when an item is temporarily rearranged so that a certain user can easily operate it, it is possible to return to the default arrangement screen simply by turning off the power and restarting.
On the other hand, when it is desired not to change the arrangement temporarily as described above but to change the arrangement completely (to change or update the contents of the screen data 22 itself), the power is turned off after the relocation. The user may operate the “edit / save” button 42 at any time before.

  Thereby, the programmable display 1 reflects the rearrangement position information of all items in the position change list 24 on the screen data 22 on the flash ROM 12. That is, for example, as shown in FIG. 5, for each item (unique No. and rearrangement position information) in the position change list 24, the item of the item on the screen data 22 corresponding to the item (the same No.) Overwrite / update the default position information with the relocation position information.

  Further, the updated screen data 22 may be transferred to the drawing editor device 5 continuously or in response to a “transfer” button operation (not shown). In the example shown in FIG. 3, the screen data 22 is uploaded to the drawing editor device 5, and the drawing editor device 5 replaces its screen data file 32 with the screen data 22 as described above (for example, Overwrite update). Thus, for example, as shown in FIG. 6, when the screen is displayed on the drawing editor device 5 side, the content after the rearrangement (“switch” has been moved) is displayed.

  Conventionally, when changing the position of an item (numerical value display, switch, etc.) on a programmable display, it was necessary to edit the screen image with drawing software and transfer it to the display each time. Convenience is improved by enabling rearrangement (adjustment) on the container side.

In addition, screen management similar to the conventional screen can be performed by drawing the final adjustment screen from the screen design software.
Hereinafter, the processing operation of the programmable display device 1 will be described in more detail with reference to flowcharts and the like. In the following description, it is assumed that the button is pressed twice to return to the “normal operation” mode. In other words, for example, when the “screen edit” button 41 is operated in the “normal operation” mode as described above, the screen shifts to the “screen edit” mode, but when the “screen edit” button 41 is operated in the “screen edit” mode, Return to "operation" mode. It should be noted that after the “edit save button” 42 is operated, the mode automatically returns to the “normal operation” mode as soon as the update of the screen data is completed (or as soon as the transfer to the drawing editor device 5 is completed). .

7A to 7D show specific examples of the item rearrangement operation.
FIGS. 8A and 8B are process flowcharts relating to item rearrangement.
FIG. 9 is a processing flowchart for editing and saving.

Hereinafter, a more detailed description will be given with reference to FIGS. 7, 8, and 9.
First, FIGS. 7A to 7D show two item displays of “numerical value” and “switch”, “screen edit” button 41, “edit save” button as in the example shown in FIG. The example of a screen on which 42 etc. are displayed is shown. FIG. 7A shows the default item arrangement state, and FIG. 7D shows the item arrangement state after movement.

The various buttons are obtained by adding “screen edit” and “edit save” to the function of the switch of the V-SFT software which is the drawing software by the present applicant, for example.
For example, on the screen editing screen on the drawing editor device 5 side, a “screen editing” switch (a switch in which “screen editing” is set in the switch function) is arranged on the screen, and an “edit save” switch (switch In this case, the screen data is transferred to the programmable display 1 after arranging a switch whose function is set to “edit save”. However, the present invention is not limited to this example.

  In this description, the “screen edit” button 41 and the “edit / save” button 42 may be referred to as a “screen edit” switch 41 and an “edit / save” switch 42, respectively.

  On the programmable display 1, the “screen editing” switch 41 is pressed during the “normal operation” mode to shift to the “screen editing” mode. As described above, in this description, switching between the “normal operation” mode and the “screen editing” mode is performed by a toggle operation.

This will be described with reference to the flowchart of FIG.
With respect to screen editing, the programmable display device 1 starts or ends processing, for example, by operating a “screen editing” button 41. That is, when it is detected that the “screen editing” button 41 is operated (pressed) (step S11, YES), if the current mode is the “normal operation” mode (step S12, YES), the “screen editing” mode is selected. (Step S13). On the other hand, when the current mode is the “screen editing” mode (step S12, NO), the mode is switched to the “normal operation” mode (step S14), and the screen editing process is ended.

  When the mode is switched to the “screen edit” mode, an arbitrary item selection operation wait state is subsequently entered, and when it is detected that an arbitrary item has been selected (step S15, YES), an item selection frame (guide frame) ) Is displayed (step S16).

  For example, as shown in FIG. 7A, it is determined that the item is selected when the user touches (presses the display position) an arbitrary item (here, “switch”) with a finger, for example. Then, the illustrated guide frame (for example, a blue frame) is displayed for the selected item. In the illustrated example, each item has an item name such as “switch” displayed in a rectangle, and the guide frame has a frame substantially similar to the rectangle in a predetermined color (for example, blue). Although displayed, it is not limited to this example.

  In any case, the guide frame indicates the user operation destination, and when the user performs a drag operation on the selected item from the state shown in FIG. 7A, the guide frame is, for example, FIG. 7B or FIG. As shown in FIG. 7 (c), the movement follows the drag operation.

  At that time, a guide frame may be displayed at a position where the item can be rearranged. All items on the screen individually have position information (X coordinate, Y coordinate) and item size (X size, Y size). Thereby, the area occupied by each item on the screen can be determined. The same applies to the guide frame. As a result, it is possible to determine whether the area occupied by the current guide frame overlaps with the area occupied by other items, so it is possible to determine the position where relocation is possible and display the guide frame according to the determination result. I do. This displays, for example, a guide frame centered on the current drag position coordinate and overlaps the display area of all other items (except for the selected item (= moving item)). The guide frame is displayed only when it is not necessary.

The above process will be described with reference to FIG.
Here, when the process of step S16 is executed, the process shifts to an “item selecting” state, and the process of FIG. 8B is executed as needed during the “item selecting” state. In FIG. 8B, during the drag operation (step S21, YES), the area occupied by the guide frame corresponding to the drag position (position pressed by the finger) is compared with the area occupied by each other item. If it is determined that the guide frame does not overlap with any of the other items, it is determined that this position is a repositionable position (step S22, YES), and the guide frame is displayed at this drag position.

  On the other hand, if the guide frame overlaps any one or more other items, it is determined that this position is not a repositionable position (step S22, NO), and is displayed at, for example, a default position (step S24). ).

  From the state shown in FIG. 7B or FIG. 7C, when the user releases his / her finger (drops / releases) from the touch panel at an arbitrary position, the display position of the guide frame at that time is changed. It is determined as the movement destination position (relocation position). Therefore, for example, if the guide frame is dropped (released) at a position that is not a repositionable position, the guide frame is displayed at the default position by the process at step S24, and therefore the determination at step S25 described later is NO. become.

  If the drop / release operation is detected, the determination in step S21 is NO, and the process proceeds to step S25 and subsequent steps. That is, first, the rearrangement position coordinates and the position coordinates before movement (default position coordinates) are compared to determine whether or not they are the same / substantially the same (step S25). When both are the same / substantially the same, it is determined that there is no position change (step S25, NO), the guide frame is deleted without performing the rearrangement (step S27), and this process is terminated. .

On the other hand, if both are not the same / substantially the same, it is determined that there is a position change (step S25, YES), and a rearrangement process is executed (step S26).
As described above, this rearrangement process is performed by the unique number of the item to be moved. And the coordinates (X coordinate, Y coordinate) of the rearrangement position are registered in the position change list 24 on the RAM 13. However, at that time, the unique number of the item to be moved is changed. However, it may be determined whether or not the position change list 24 has already been registered. This assumes the case where the same item has already been rearranged, but is moved further due to reasons such as the rearrangement position being unusable (or the user changing). Thus, the unique number of the item to be moved is changed. Is not registered in the position change list 24, this unique No. And the rearrangement position coordinates are newly registered in the position change list 24. On the other hand, this unique No. However, if it is already registered in the position change list 24, the existing position information is rewritten (new relocation position coordinates are overwritten).

  When the rearrangement process in step S26 is completed, the guide frame is deleted in step S27, and this process is terminated. Since the item display control in this method is performed with priority on the position change list 24 as described above, the “switch” is displayed at the rearrangement position as shown in FIG. This does not change even when the mode is returned to the “normal operation” mode, and the “switch” is displayed at the rearrangement position shown in FIG.

As already described, since the display is performed with priority on the position change list 24, items are displayed at the rearrangement position thereafter. That is,
The individual item display is displayed according to the position information in the list if the position information is in the position change list 24, and is displayed according to the position information of the screen data 22 if it is not in the list. Display attributes other than items are displayed according to the information of the screen data 22. (Individual items can be checked for the presence or absence of the item position information in the position change list 24 by its unique number.)
As described above, the display operation by the screen data 22 and the position change list 24 after the item rearrangement does not depend on the mode (“normal operation” mode / “screen edit” mode).

  During the “normal operation” mode, not only the display but also the item corresponding to the user's operation (pressing) position is determined with priority given to the position change list 24. Therefore, in the state shown in FIG. 7D, even if the user presses the original “switch” display position (position shown in FIG. 7A), the switch operation is not performed.

Next, the processing operation related to the “edit / save” switch will be described with reference to the flowchart of FIG.
In FIG. 9, when the programmable display 1 detects that the user has performed an operation of pressing the “edit / save” switch 42 (step S <b> 31, YES), the programmable ROM 1 uses the position information in the position change list 24 on the RAM 13 to indicate the flash ROM 12. The position information of the upper screen data 22 is updated (step S33). Of course, only the items registered in the position change list 24 have their position information updated. As described above, each item is identified with a unique number. Can be done by.

  However, before that, it is determined whether or not the position change list 24 has been updated (new registration of one or more items) (step S32), and only when there is an update (step S32, YES), the process of step S33 is performed. You may make it perform.

  After the position change list 24 is reflected on the screen data 22 on the flash ROM 12 by the process of step S33, the position change list 24 on the RAM 13 is deleted (step S34).

  Thereafter, the position change list 24 is displayed with priority, but since there is no registration information of the position change list 24, all items are displayed based on the screen data 22 on the flash ROM 12 until new registration is made in the position change list 24. Will be displayed.

The “edit / save” switch 42 and the processing of FIG. 9 allow the user to arbitrarily select whether to change the item arrangement temporarily or to update the screen data 22 itself.
If necessary, the drawing editor device 5 may read the screen data from the programmable display device 1 and manage it with V-SFT software.

Each term can be defined, for example, as follows, but is not limited to this definition example.
Unique number; number uniquely determined to identify each item; position information; coordinates (X coordinate, Y coordinate) indicating the position of the item on the operation / display screen, for example, an item The coordinates of the center of the item and the coordinates of the upper left corner of the item.
Item size: Item horizontal size (X size), Vertical size (Y size), etc. Item information: Unique number, position information, other display attributes (item size, color, display character, etc.)
-Position change list 24: A list of information in which the unique number and destination position information are collected for the item whose arrangement has been changed. As described above, according to this method, an arbitrary item is selected on the programmable display. By performing a predetermined operation (for example, by dragging and dropping), it is possible to easily rearrange items. Thereby, fine adjustment of a screen, a temporary change, etc. can be performed easily. Of course, even when the screen is completely changed (not temporarily), the trouble of downloading and the like can be saved. As described above, according to the programmable display of this example, the arrangement of the item images on the screen can be changed on the programmable display side, and the display screen can be customized without taking time and effort. In addition, temporary changes and complete changes can be selected.

  Also, the screen data after adjustment / change can be managed by the same method as before by sucking the screen data from the programmable display to the drawing software of the drawing editor device. For example, conventionally, the screen data of the programmable display device is held on the drawing editor device side, and if the screen data on the programmable display device side is erased / damaged for some reason, the screen data is again displayed on the drawing editor device side. Downloaded to a programmable display. Even when the screen data of the programmable display is updated by this method, it is necessary to upload the updated version of the screen data to the drawing editor device in order to realize the conventional management.
