Description

  The present invention relates to a programmable display and the like.

  In general, a programmable display is connected to various connected devices such as a PLC main body and a temperature control device, and items such as numerical displays and lamps for displaying the status of these connected devices, and for users to give arbitrary instructions. Displays an image of items such as switches. An item is also called a screen component or the like. Usually, images of a plurality of screen components (items) are displayed on the screen of the programmable display (referred to as an operation display screen).

  Data or the like for displaying such an operation display screen (referred to as screen data or the like) is arbitrarily created in advance by a developer or the like in a support device (not shown) and downloaded from the support device to a programmable display. .

  The screen data includes, for each item, an image of the item (switch image, lamp image; or image identification ID, etc.), display position coordinates, and an address (assignment memory) of a predetermined area of an external memory to be described later. Address) and the like are included. In addition, some programs may be included.

  Each of the items is for displaying the state of the component or accepting an ON / OFF instruction for the component corresponding to an arbitrary component of an arbitrary connected device, for example. For example, in the case of an item that displays the temperature measurement value of the temperature control device as a numerical value, the current temperature is displayed as a numerical value as needed.

  Display control related to the various items in the programmable display is realized, for example, by periodically executing predetermined processing for each item. Predetermined processing refers to, for example, reading stored data in the predetermined area (area of allocated memory address) of a memory device (external memory) in the connected device and determining the display content of the item based on this stored data・ It is to be displayed. The connected device updates the stored data in a predetermined area of the external memory as needed (for example, the temperature measurement value is updated as needed in the temperature control device).

  Further, the data read from the external memory is temporarily stored in a predetermined area of a memory device (referred to as internal memory) in the programmable display, and the display contents of the item are determined and displayed based on the stored data. There is also a configuration.

  In the case of this example, the process of reading the data stored in the external memory and storing it in the internal memory is executed, for example, periodically by a predetermined functional unit (here, a communication unit not shown) of the programmable display. The communication unit communicates with various connected devices such as the PLC main body and the temperature control device, for example, acquires data stored in a predetermined storage area of the external memory in the connected device, and stores the data in the internal device Overwrite and store in a predetermined area of memory. And the function part (it shall be called an item display part) which performs the display control which concerns on the said various items in a programmable display controls an item display content by accessing an internal memory regularly.

  Here, the operation display screen for causing the display operation to be performed on the programmable display is arbitrarily created by the developer or the like in the support device as described above. However, it is not always possible for the developer to create freely. For example, based on the image image of the entire operation display screen (entire screen) created in advance by a designer or the like, the above operation display is made so that at least the appearance is close to this image image. There are many cases where screens are created.

  In the support device, images of various items are stored in advance. For example, item images of various designs are created in advance for each item type (switch, lamp, meter, etc.) and stored in the storage unit of the support apparatus.

  As for the item image, for example, with respect to the switch, images of switches having various designs with different colors, shapes, expressions (for example, woodgrain, metallic tone, etc.) are created and registered in advance. Further, for each design, a plurality of types of switch images (for example, for ON and OFF; switch ON image and switch OFF image) are created and registered in advance.

  Similarly, lamp images of various designs with different colors, shapes, expressions, etc. are created and registered in advance. Further, for each design, a plurality of types of lamp images (for example, for ON and OFF; lamp ON image and lamp OFF image) are created and registered in advance.

  A developer or the like arranges the item image related to an arbitrary item at a desired position on the screen. For example, a developer arranges a switch image of a desired design at a desired position on the screen. In general, all the above-mentioned plural types of images (for example, for ON and OFF) of the design are registered as being arranged at the same position. For example, when a developer or the like places a switch-on image with a desired design at a desired position, the switch-off image with the same design is also registered as being placed at the same position (the developer performs an operation to place the switch-off image. Do not need to do). Of course, for this purpose, for example, a plurality of types of switch images having the same design are registered in groups, for example. Similarly, a developer or the like places a lamp image of a desired design at a desired position. However, the “desired” is not limited to an example that the developer may freely decide, but may be one corresponding to the image of the entire screen as described above.

In addition to selecting / arranging the image, an operation for setting the allocated memory address is performed for each arranged item.
Further, for example, the prior art described in Patent Document 1 is known.

In the prior art of Patent Document 1, when the HMI processing unit of the programmable display device accepts a predetermined operation in the offline mode, the color tone of the setting screen that can be displayed in the offline mode and / or according to the operation. Change the design all at once. Further, the HMI processing unit displays a screen that prompts an input as to whether or not to display a predetermined setting item among the displayable setting items in the offline mode, and in response to an operation on the screen. , Whether to display the setting item.
JP 2006-134095 A

  As described above, in the prior art, the creation of the operation display screen (programmable display screen) is performed by a developer or the like selecting and arranging item images one by one in the support device. Here, particularly when there is an image of the entire screen, it is desired to improve the efficiency of creating the operation display screen by effectively using the image.

  Furthermore, with any operation display screen already created (especially in the state already operated on the programmable display side), only the image (design) can be displayed without changing the type or arrangement position of each item. You may want to change it. It is desirable to be able to easily perform the changing work in such a case.

The subject of this invention is providing the programmable display etc. which can perform the creation operation and design change operation of the screen for programmable displays easily.
The programmable display of the present invention is the programmable display in a programmable controller system having a programmable display and a support device, and the screen data created based on the entire screen image in the support device and the entire screen image are displayed. Screen data storage means for storing, part image generating means for generating a part image by cutting out the specified area portion from the entire screen image based on the specified area information of the screen data for each item, and the generation Item display means for performing display related to the item using the part image to be displayed.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic configuration diagram of the entire system including the programmable display of this example.
The programmable controller system shown in FIG. 1 includes various connection devices 4 and a programmable display 1 that is connected to the various connection devices 4 via a communication line 6. Furthermore, the structure by which the programmable display 1 was connected to the drawing editor apparatus 5 (support apparatus) via the communication line 3 may be sufficient. The programmable display 1 is provided with a plurality of communication interfaces 2 (communication ports), and is connected to various connection devices 4 and the drawing editor device 5 by the communication line 3 / communication line 6 connected to each communication interface 2. ing.

  However, the drawing editor device 5 does not necessarily need to be connected to the programmable display device 1 (only an example is shown). That is, for example, screen data created by the drawing editor device 5 and an entire screen image to be described later are downloaded from the drawing editor device 5 to the programmable display device 1 via the communication line 3 as an example. Not exclusively. For example, the screen data and the entire screen image of the drawing editor device 5 may be transferred to the programmable display device 1 via a portable recording medium (not shown) such as a memory card.

In the following description, the drawing editor device 5 may be referred to as the support device 5.
FIG. 2 is a configuration example of the programmable display 1 of this example.
With respect to the programmable display device 1 of this example, there is an example in which operation similar to that of the conventional example described above is performed. That is, there is an example in which an operation display screen is displayed based on screen data or the like (however, a part image (which corresponds to each item image described above) described later is used) (second embodiment described later).

  Alternatively, with respect to the programmable display 1 of the present example, there is an example in which a part image (corresponding to each item image) is extracted from the entire screen image and this part image is displayed at a predetermined position (implementation described later). Example 1). Details will be described later.

The illustrated programmable display 1 includes a display operation control device 10, a touch panel 18, a display 19, the communication interface 2, and the like.
The display operation control device 10 includes a CPU 11, a ROM 12 (flash memory or the like), a RAM 13, a communication controller 14, a graphic controller 15, a touch panel controller 16, and the like, which are connected to a bus 17.

  The CPU 11 is a central processing unit (arithmetic processor) that controls the entire display operation control device 10. The CPU 11 performs a predetermined calculation operation (processing) by executing a program (for example, a main body program 21 described later) stored in the ROM 12 in advance. For example, various processes of the programmable display 1 of this example described later are executed. Various calculation results are stored in, for example, the RAM 13.

  The ROM 12 stores screen data (screen data 22 to be described later) described in the background art. As described above, the screen data includes, for example, data relating to display such as the display position coordinates and size for each item such as the above-described switch and lamp, and memory access such as the allocated memory address (allocated memory area). Data related to However, the conventional screen data includes each item image (or the identification ID of the item image). In the first embodiment of this example, instead of the item image, the entire screen image (or its identification) ID etc.) are included.

  The processing of the CPU 11 includes, for example, processing for obtaining “storage data such as an allocated memory address for each item” (storage data in a predetermined area of the external memory) described in the background art. This acquired data is temporarily stored, for example, in the shared memory 55 described later. The shared memory 55 may be a part of the storage area of the RAM 13 or the ROM 12, or may be another memory (not shown).

  Further, display target data based on the screen data, the acquired data, and the like are developed (drawn) on, for example, the RAM 13 (or a video RAM (not shown)) by the processing of the CPU 11. Based on this drawing, the graphic controller 15 displays the above-described operation display screen on the display 19.

  In the conventional case, as described above, at least two types of images for ON and OFF, for example, are created and registered in advance for each design as described above. For example, taking a lamp as an example, as an item image, a lamp-off image and a lamp-on image are registered for each design. On the programmable display 1 side, for example, if the acquired data is “0”, the lamp extinguished image becomes the display target data (drawn).

  On the other hand, in the case of the first embodiment, for example, an entire screen image for ON and an entire screen image for OFF are registered in advance. For example, if the acquired data is “0”, a part image corresponding to the lamp extinguished image is cut out from the entire screen image for OFF and drawn. Similarly, for example, if the acquired data is “1”, a part image corresponding to the lamp lighting image is cut out from the entire screen image for ON and drawn.

  Further, in the case of the second embodiment, various images of parts (images corresponding to conventional item images) from various screen whole images (for example, for ON and OFF) of an arbitrary design in advance on the support device (drawing editor device 5) side. The various parts images are included in the screen data and downloaded to the programmable display 1. The processing operation on the programmable display 1 side may be substantially the same as the conventional one (a part image is used instead of the item image). Details will be described later.

  Conventionally, the current state (for example, on the connected device 4 side) can be determined based on the acquired data. In other words, the conventional cases of the first embodiment and the second embodiment are substantially the same in that the current state is determined at any time and the image is displayed according to the current state (for example, regarding the lamp, If the state is ON, the lamp lighting image or “part image corresponding to the lamp lighting image” is displayed).

  As described above, the difference between the first embodiment and the second embodiment of the present technique is that the part image cut-out process (the image generation process corresponding to the conventional item image) from the entire screen image is performed by the programmable display 1. Or at any time or periodically depending on the current state, or in advance by the support device (drawing editor device 5). In any case, it is possible to easily generate the operation display screen, change the design of the operation display screen, and the like by effectively using the entire screen image. Details will be described later.

  The display 19 is composed of, for example, a liquid crystal panel, and a touch panel 18 is provided so as to overlap the liquid crystal panel. Conventionally, an operation display screen in which a plurality of item images are arranged at predetermined positions is basically displayed on the display 19. In the case of this example, basically, an operation display screen in which a plurality of part images are arranged at predetermined positions is displayed on the display 19.

  Further, the communication controller 14 performs communication (data transmission / reception and the like) with the connection device 4 and the drawing editor device 5 such as a PLC main body (not shown), a temperature control device, and the like via the communication interface 2.

  The detection result of the pressing operation (touch) position on the touch panel 18 by an operator or the like is taken into the CPU 11 or the like via the touch panel controller 16 and analyzed. For example, analysis is performed based on the display position coordinates and size data of each item. For example, when an operator or the like touches the display position of the image of the switch, the CPU 11 or the like analyzes that an operation on the switch has been performed.

FIG. 3 shows a software configuration diagram of the system.
In the programmable display 1, various programs / data such as a main body program 21, screen data 22, and communication program 23 are stored in, for example, the ROM 12 (flash memory or the like). The CPU 11 reads / executes / references these programs / data, etc., thereby performing display control of the operation display screen for the programmable display.

  Conventionally, this operation display screen is composed of the above-described numerical display, image display of various items such as lamps, switches, and the like, and the display contents of each item image are obtained from, for example, each connected device 4 (external memory; allocated memory area). It is updated from time to time to reflect the data (acquired data). On the other hand, in the case of this example, the operation display screen is display-controlled using “the part image corresponding to the item image” instead of the item image.

  Basically, the operation display screen is displayed by the CPU 11 performing processing based on the main body program 21 and the screen data 22 (including the part image or the entire screen image). The display contents of each screen component on this operation display screen (numerical display such as temperature, lighting / extinguishing of lamp, etc.) are shown in the communication result with each connected device 4 by the communication program 23 (the acquired data etc.). Based on this, it is updated as needed.

  The screen data 22 is obtained by, for example, downloading a part or all of the screen data file 32 arbitrarily created in advance on the drawing editor device 5 side to the programmable display 1 and storing it. Note that the screen data file 32 and the screen data 22 may be referred to as screen data or screen data 22 without particularly distinguishing them.

  Conventionally, the screen data includes various item images, but the screen data 22 of the present example includes various parts images or various entire screen images. However, the present invention is not limited to this example, and various part images or various whole screen images may be stored separately from the screen data 22.

  Also, the communication program 23 is a program in which, for example, a communication program file 33 (part thereof) stored in advance on the drawing editor device 5 side is downloaded and stored in the programmable display device 1.

  As described above, basically, the CPU 11 performs display control of the operation display screen based on the main body program 21, the screen data 22, and the acquired data. For example, regarding an item such as a numerical display or a lamp, data is periodically read from the allocated memory area of the item, and the display content of the item is updated based on the read data. Alternatively, for example, regarding an item such as a switch, when a user touches a desired switch on the operation display screen (when an ON / OFF operation is performed), switch ON image display / switch OFF image display is performed. The CPU 11 also controls the connection device 4 according to the switch operation.

  Here, in the case of this method, the switch ON image, the switch OFF image, and the like are the part images generated from the entire screen image. In the first embodiment, this part image is generated according to the current state at any time or periodically on the programmable display 1 side. On the other hand, in the second embodiment, all the part images corresponding to, for example, an arbitrary design are generated in advance on the support device 5 side. However, the present invention is not limited to this example, and all part images corresponding to, for example, an arbitrary design may be generated in advance on the programmable display 1 side. In any case, the part image is generated from the entire screen image.

  When various parts images are generated from the entire screen image, and when it is desired to change the design of the operation display screen entirely (however, basically, the arrangement and functions are not changed), the entire screen image The design can be changed and the burden of changing work is reduced.

  The allocated memory area corresponds to a predetermined storage area (allocated memory address) of the external memory in the background art. Note that a shared memory 55 described later corresponds to the internal memory.

  As already described in the related art, the external memory is a memory provided in the connection device 4, and the memory allocation of each item is performed. As described above, the display content of each item is determined and updated based on the stored data in the allocated memory area.

  As described above, the read data from the allocated memory area is temporarily stored in the internal memory (shared memory 55) in the programmable display 1, and the item display control is performed based on the stored data. There is an example.

  That is, for example, a process of periodically reading data from a predetermined storage area of a memory device (external memory) in the connection device 4 and storing the read data in the internal memory by each communication processing unit 54 or the like described later. Done. Then, for example, the item processing unit 53 described later performs display control of the operation display screen based on the data in the internal memory. As a result, the display content of the operation display screen reflects the content of the current stored data in the allocated memory area corresponding to each item (according to the current state).

  The support device 5 (its drawing editor 31) includes an entire screen image storage unit 31a, a screen creation support unit 31b, and the like. In the entire screen image storage unit 31a, various entire screen images are stored in advance. Conventionally, the entire screen image itself has been created by a designer or the like for showing the entire image. The entire screen images of various designs stored in the entire screen image storage unit 31a are displayed in a list in the image display selection area 41 described later.

  The screen creation support unit 31b causes the user to create a desired operation display screen (screen data) using the entire screen image. This is, for example, a user support process described later with reference to FIGS. 4 and 5 and will be described in detail later.

  Note that the drawing editor device 5 is, for example, a personal computer or the like, and has a general-purpose computer configuration (CPU, storage unit (hard disk, memory, etc.), communication unit, operation unit (mouse, etc.), display) although not particularly shown. Have. When the CPU executes an application program stored in advance in the storage unit, for example, the processing function of the screen creation support unit 31b is realized.

  FIG. 4 and FIG. 5 show examples of screens for supporting creation of a programmable display screen (operation display screen; screen data) in the support device 5 of this example. This screen example itself may be common to the first and second embodiments. However, in the case of the second embodiment, along with the screen data creation work in this screen example, processing (part image generation processing) for cutting out various part images from the entire screen image is performed on the support device 5 side. In the case of Example 1, a part image is generated on the programmable display 1 side.

Moreover, in FIG. 6, the example of the operation display screen of the programmable display in Example 1 is shown.
Hereinafter, a description will be given with reference to FIGS. 4, 5, and 6. In this description, switches and lamps are used as item images. However, the present invention is not limited to this example (as is well known, various item images such as graphs, meters, and numerical displays are also known. ing). In this example, a part image corresponding to a conventional item image is generated, and display control of the operation display screen is performed using the part image.

Hereinafter, description will be given first with reference to FIGS.
FIG. 4 is a main screen for screen data creation support in the support apparatus.
The illustrated main screen 40 includes an image display selection area 41 and a screen creation area 42.

  Conventionally, there are those corresponding to these areas (referred to as a conventional image display selection area and a conventional screen creation area not shown). Conventionally, various item images are displayed in a list in the conventional image display selection area. For example, switch images for various designs for switches (for example, there are ON and OFF images for each design), and lamp images for various designs (for example, ON for each design) Are displayed in a list in the conventional image display selection area. Of course, these various item images are created in advance and stored in a storage unit (hard disk / memory, etc.) (not shown) of the conventional support apparatus.

  Thus, conventionally, the user operates the mouse or the like to select (drag) a desired item image from various item images displayed in a list, and arrange this at a desired position on the conventional screen creation area. (Drop). For example, the allocated memory address is set for this item. With such an operation, an item image, an arrangement position on the screen, an allocated memory address, etc. are set and registered in the screen data for an arbitrary item. When the user repeats such an operation, the operation display screen (screen data) with a plurality of items is usually created.

  On the other hand, in the case of this example, various screen whole images are registered in advance instead of the various item images. For this, for each design, an entire screen for ON and an entire screen for OFF are registered in advance. Then, the registered entire screen image is displayed in a list in the image display selection area 41. FIG. 4 shows the entire screen image 43 for ON and the entire screen image 44 for OFF related to one design. Normally, the entire screen image is registered for a plurality of designs.

  Of course, for this purpose, it is necessary to create an entire screen image (for example, for ON and OFF) in advance for each design, and when adding a new design, a new entire screen image for that design is created. The work to do is also necessary. However, even in the past, there are not a few cases where a designer or the like has created an entire screen image in advance, and this method can also effectively use this. Furthermore, in such a case, the operation display screen is basically created so as to be substantially the same as the entire image created by the designer or the like, so in this method, the position of each item image is confirmed one by one. The effect that the operation | work of arrangement | positioning etc. becomes unnecessary is also acquired. That is, the burden of creating the operation display screen can be reduced. Furthermore, it is possible to reduce the burden of changing work when the design is changed (however, only the design is changed, and the position and the like are not changed).

  In the figure, for convenience of explanation, both the entire ON screen image 43 and the entire OFF screen image 44 are displayed in the image display selection area 41, but only one for each design (for example, the ON screen). Only the entire image) may be displayed in the image display selection area 41.

  In addition, it can be said that the ON screen whole image 43 shown in the drawing shows an operation display screen when all the items on the screen are all in the ON state. Similarly, it can be said that the OFF whole screen image 44 shown in the drawing shows an operation display screen when all items on the screen are all in the OFF state. On the other hand, on the operation display screen in the programmable display device 1 in operation, there are usually items in an ON state and items in an OFF state.

  When the user selects and designates an entire screen image of a desired design from the entire screen images displayed in the image display selection area 41 by a mouse operation or the like, the designated entire screen image is displayed in the screen creation area 42. Is displayed. Then, when the user performs the following operation on the screen creation area 42 in this state, a desired operation display screen (its screen data) is created.

  Note that the screen data may be regarded as almost the same as, for example, an item list 56 described later. Therefore, if it is described using a specific example of the item list 56 shown in FIGS. Item type (switch, lamp, etc.), position information (coordinates and size), allocated memory address, ON image No. , OFF image No. The predetermined information such as is registered.

  The entire screen image includes images of a plurality of items (here, images of a plurality of lamps and images of a plurality of switches) as illustrated. The user surrounds a desired region (region desired to be made into a part) on the entire screen image by a mouse operation or the like (the bold dotted line rectangle in the figure). This operation corresponds to a conventional “place the selected item image at a desired position” operation. That is, the thick dotted-line rectangular image shown in the figure (a part of the entire screen image; the above part image) corresponds to a conventional item image. By this operation, addition of a new record of screen data is started.

  In other words, if a specific example of the item list 56 is used, a new record is added to the screen data by the user operation (part image area designation), and the data item of the coordinate or size includes the bold dotted line rectangle. Stores coordinates and size. Conventionally, the information on the place where the selected item image is arranged is stored in the data item of the coordinates and size. Furthermore, the ON image No. of the new record. , OFF image No. In the data item, an identification ID (in this case, for ON and OFF) of the selected entire screen image is stored (in the case of the first embodiment). Of course, a unique identification ID is assigned to each entire screen image in advance.

  Conventionally, the identification ID (for ON and OFF) of the selected item image is the ON image No. , OFF image No. Stored in the data item. In the case of the second embodiment, as described later, when various part images are generated on the support device 5 side, an identification ID is assigned to each part image. The identification ID of each part image is the ON image No. of the new record. , OFF image No. Will be stored in the data item.

  When the user performs an operation (part image designation operation) surrounding the desired area, a data storage process for the predetermined data item is performed and, for example, an item conversion window 45 shown in FIG. 5A is displayed. . The user selects / designates a desired item type (switch, lamp, etc.) on the item conversion window 45. The selection / designation result is stored in the item type data item in the new record.

  In the conventional case, since an item type is assigned to each item image in advance, the item type of the arranged item image is stored in the data item of the item type. In the case of this method, the image (part image) within the bold dotted rectangle corresponds to a conventional item image, but this is merely mere image data, and a person determines and sets the item type. There is a need.

  Then, a setting window 46 shown in FIG. 5B corresponding to the selected / designated item type is displayed. Since this may be the same as the conventional one, it will not be described in detail, but in the illustrated example, a setting window 46 corresponding to the lamp is displayed, and for example, an arbitrary allocated memory address can be set. This setting content is stored in the data item of the allocated memory address.

  As described above, various settings relating to an arbitrary item (designation of the region of the part image, setting of an item type and an allocated memory address related thereto, etc.) are completed. Screen data is created by performing this operation for each location on the entire screen image (basically, a portion having a switch, a lamp, etc.).

  As described above, a user-desired operation display screen (its screen data) is created, but this screen data itself may be substantially the same as the conventional one except for a part. The difference from the prior art is that the ON image No. And OFF image No. It is.

  That is, conventionally, the identification IDs of the item images (ON and OFF) arranged on the conventional screen creation area are the ON image No. And OFF image No. Stored in On the other hand, as described above, in the case of the first embodiment, the identification ID (ON and OFF) of the entire screen image of the design selected and displayed in the screen creation area 42 is the ON image No. And OFF image No. Stored in As described above, in the case of the second embodiment, the support device 5 performs processing for generating the various part images from the entire screen image, and for identifying these various part images (for ON and OFF). ID is the ON image No. And OFF image No. Will be stored.

  Conventionally, each item image is transferred to the programmable display device 1 and stored together with the created screen data (or separately). On the other hand, in this method, together with the generated screen data (or separately), the entire screen image or each part image is transferred to the programmable display 1 and stored.

  The screen data created by the screen data creation operation on the support device 5 side described above and transferred to the programmable display 1 (here, the entire screen image is also transferred together) is stored in the programmable display 1 Is stored in the ROM 12 (flash memory or the like). This whole screen image is a whole screen image (for ON and OFF) of the design used for generating screen data on the support device 5 side. However, the present invention is not limited to this example, and whole screen images of various designs may be stored in the programmable display 1 in advance.

  The programmable display 1 displays, for example, an operation display screen 47 shown in FIG. 6 on the display 19 using the screen data stored in the ROM 12 or the like and the entire screen image. Basically, for each item of screen data, an image of the corresponding area of the item is obtained from the entire screen image corresponding to the current state of the item (that is, the entire screen image for ON in the ON state). The part image is generated by cutting out. Then, the generated part image is displayed at a predetermined position on the display 19 based on the position information of the item.

  In addition, in the example shown in FIG. 6, not only each part image but also characters such as “REAL MONITOR” shown in the figure are displayed. is there. That is, in the default state, all items are displayed in the OFF state.

  Then, after the operation is started, for an item that is in the ON state, a part image cut out from the entire ON screen image (referred to as an ON part image) is drawn at a predetermined position on the background. As a result, the display content related to this item changes from the OFF state to the ON state.

  On the other hand, for an item in the OFF state, a part image cut out from the entire OFF screen image (referred to as an OFF part image) is drawn at a predetermined position on the background. As a result, the display content relating to this item changes from the ON state to the OFF state. However, when the display is originally in the default state, at least from the user's viewpoint, the display remains in the OFF state and the display content does not change.

  Here, there is a case where the design change of the display operation screen is desired. For example, in the present situation, the design shown in the left or center of FIG. 4 or 6 is changed to the design shown in the right side of FIG. 6 (referred to as a new design). Think of a case. Here, it is assumed that only the design is changed, and the arrangement, type, function, allocated memory address, etc. of each item are not changed.

  In such a case, conventionally, the developer or the like on the support apparatus 5 side creates and registers each item image based on the entire screen image of the new design, and then uses each item image or the like of the new design. It was necessary to create a new operation display screen. On the other hand, in this method, it is only necessary to replace the entire screen image of the old design held on the programmable display 1 side with the entire screen image of the new design.

  At this time, the identification ID of the entire screen image of the new design may be the same as the identification ID of the entire screen image of the old design. However, the present invention is not limited to this example. For example, the ID for identification of the whole screen image of the new design is a new unique identification ID. 66 and ON image No. 67 may be changed to the ID for identification of the entire screen image of the new design. In any case, anything may be used as long as the part image is generated using the entire screen image of the new design during the screen display process.

  After the change of the whole screen image, the part image is cut out and displayed from the whole screen image of the new design shown on the right side of FIG. 6, and as a result, the operation display screen based on the new design is displayed. It becomes like this.

FIG. 6 shows a display example of the operation display screen of the programmable display.
FIG. 7 is a processing function diagram of the programmable display 1 of this example.
The programmable display 1 stores screen data 22, an entire screen image 57, and the like. The entire screen image 57 is stored in association with the identification ID.

  When the CPU 11 executes a predetermined program (for example, the main body program 21, the communication program 23, etc.) stored in the ROM 12, for example, various processing function units shown within a dotted line in FIG. 7 are realized. That is, the following processing functions of various processing function units such as the item generation unit 51, the item processing schedule unit 52, the item processing unit 53, and the communication processing unit 54 (54-1, 54-2, etc.) shown in the figure are realized.

  For example, the item generation unit 51, the item processing schedule unit 52, and the item processing unit 53 are realized by the main body program 21. The communication processing unit 54 is realized by the main body program 21 and the communication program 23.

  The item generation unit 51 generates an item list 56 based on the screen data 22 or the like. This is generated, for example, by extracting a part of the screen data 22 (further, a processed flag 68 described later is added).

Here, FIG. 8 shows a data structure diagram of the item list 56.
FIG. 9A shows a data storage example of the item list 56 in the first embodiment.
The item list 56 in the illustrated example includes an item type 61, coordinates 62, size 63, device name 64, address 65, OFF image No. 66, ON image no. 67, each data item of processed flag 68. Each record in the item list 56 corresponds to each item on the operation display screen. Note that the present invention is not limited to the illustrated example, and may further include an identification number of each item.

The item type 61 stores item type identification information indicating the type of the item (switch, lamp, numerical display, etc.).
OFF image No. 66 and ON image No. 67 stores an identification ID of the entire screen image 57 (for OFF and ON) of the design related to the operation display screen. As shown on the right side of FIG. The entire screen image data is registered in association with. This may be registered in advance on the programmable display 1 side (of course, registered in advance on the drawing editor device 5 side), or may be downloaded together with the screen data 22. .

  The device name 64 and the address 65 are memory allocation information related to each item, and correspond to the allocated memory address. That is, the storage area indicated by the address 65 in the memory indicated by the device name 64 is an area assigned to the item (the assigned memory area). The stored data in the allocated memory area indicates the current state of the item. For example, if the item type 61 is a lamp, the stored data includes flag data indicating lighting / extinguishing of the lamp.

  The item type 61, the device name 64, and the address 65 may be substantially the same as the conventional one. The coordinates 62 and the size 63 indicate the display area of the part image. However, in the case of the first embodiment, the coordinates 62 and the size 63 are also used when generating the part image. That is, in the case of Example 1, the OFF image No. 66 or ON image no. An image of an area corresponding to the coordinates 62 and the size 63 is cut out from the entire screen image 57 indicated by 67 to obtain the part image. The cut-out part image is displayed in a predetermined area (area indicated by the coordinates 62 and the size 63) on the display.

  Here, FIG. 9B shows a data storage example of the item list 56 ′ in the second embodiment. The example of FIG. 9B is almost the same as the example of FIG. 9A except for a part (the reference numerals are 56 ′, 66 ′, 67 ′ instead of 56, 66, 67). ), Only the differences will be described. In the item list 56 ′ shown in FIG. 66 and ON image No. In place of 67, the OFF image No. 66 'and ON image No. 67 'is stored.

  OFF image No. 66 'and ON image No. 67 'stores an identification ID or the like of the image data (part image) of the item. For example, if the item type is a switch, each switch No. However, the OFF image No. 66 'and ON image No. 67 '.

  In the case of the second embodiment, as shown on the right side of FIG. Part image data is registered in association with. This may be registered in advance on the programmable display 1 side (of course, registered in advance on the drawing editor device 5 side) or downloaded to the programmable display 1 together with the screen data 22. It may be.

  The OFF image No. 66 'and ON image No. It may be considered that the configuration in which the ID of the item image (ON and OFF) of the item is stored in 67 'corresponds to a conventional item list.

The item list 56 has been described in detail above with reference to the examples of FIGS.
Returning to the description of FIG.
The item processing schedule unit 52 illustrated in FIG. 7 performs schedule management such as display update processing of each item by the item processing unit 53. That is, the item processing schedule unit 52 periodically calls the item processing unit 53 to execute, for example, the processing of FIGS. 12 and 13 described later (in other words, the processing of FIGS. 12 and 13 is executed cyclically). )

  The item processing unit 53 updates the display contents for each item (for example, ON image / OFF, for example) based on the item list 56 and data stored in the shared memory 55 described later (acquired data from the allocated memory area). Processing related to image switching).

  The item processing unit 53 determines and updates the display content of the display operation screen based on, for example, acquired data from the allocation memory area. For example, for each item, the current state (for example, ON state / OFF state) is determined (this determination process itself is substantially the same as the conventional case), and the above-described screen entire image 57 according to the determination result A part image is cut out, and this part image is drawn (developed) on the RAM 13. As a result, the graphic controller 15 displays the drawing data on the display, whereby the display operation screen is displayed. This drawing data is updated by the item processing unit 53 whenever necessary, for example, every time processing shown in FIGS.

  The communication processing unit 54 is a communication processing unit 54-1 or 54-2 provided for each connected device 4 (4-1 or 4-2). That is, the illustrated communication processing unit 54-1 performs communication with the connection device 4-1 via the communication line 6 using the communication port WAY1 corresponding to the connection device 4-1, and the device memory Stored data in a predetermined area (allocated memory area). The acquired data is overwritten and stored in a predetermined area of the shared memory 55.

  Similarly, the illustrated communication processing unit 54-2 performs communication with the connection device 4-2 via the communication line 6 using the communication port WAY2 corresponding to the connection device 4-2, and the device. Data stored in a predetermined area (allocated memory area) of the memory is acquired. The acquired data is overwritten and stored in a predetermined area of the shared memory 55.

FIG. 10A shows an example data structure of the shared memory 55.
In the example shown in FIG. 10A, the data stored in the shared memory 55 includes data items of a port 71, a device name 72, an address 73, and data 74.

The port 71 is identification information of the communication port and the like, and is substantially information for identifying the connection device 4 of the communication partner. The device name 72 is identification information of a memory device (external memory) in the connection device 4 of the communication partner. The address 73 is an address of a predetermined storage area in the external memory indicated by the device name 72, and the data 74 stores data acquired from this storage area. Note that the device name 72 and the address 73 may be regarded as corresponding to the “allocated memory address” of each item. These are copies of the device name 64 and address 65 of the item list 56, for example. The port 71 is, for example, a communication port number determined by determining the corresponding connected device 4 based on the device name 72. Alternatively, the device name 64 may include not only the memory device name but also a communication port number.

FIG. 11 is a processing flowchart of the communication processing unit 54.
For example, in the example of FIG. 7, each of the communication processing units 54-1 and 54-2 performs the processing of FIG. 11 cyclically (at a constant cycle).

  In the processing example of FIG. 11, first, the shared memory 55 is referenced to generate the memory list 80 related to the connected device 4 that is in charge of itself (step S1). For example, in the case of processing by the communication processing unit 54-1, the memory list 80 related to the connected device 4-1 is generated.

FIG. 10B shows a data configuration example of the memory list 80.
In the illustrated example, the memory list 80 includes data items of a device name 81, an address 82, and data 83.

  For example, the communication processing unit 54-1 extracts all records in which the port 71 is “WAY 1” from the shared memory 55. The information of the device name 72, address 73, and data 74 of each extracted record is stored in the device name 81, address 82, and data 83. As a result, the memory list 80 relating to the connected device 4-1 is generated. The data 83 is not always necessary.

Thereafter, while referring to the generated memory list 80, the processes in steps S2 to S5 are repeatedly executed until the determination in step S5 becomes NO.
That is, an unprocessed record is taken out from the memory list 80 (as a process target record), a memory read command based on the contents of this record is generated, and transmitted to the connected device 4 in charge via the communication line 6 ( Step S2). Then, it waits for a response from the connected device 4 to this memory read command (step S3).

  The memory read command includes information on the allocated memory address based on the device name 81, the address 82, and the like. The connected device 4 reads out data from the storage area indicated by the allocated memory address and performs response processing for returning the read data.

  When there is a response from the connected device 4, the communication processing unit 54 overwrites and stores the read data included in this response in the column of the data 74 in the record corresponding to the processing target record in the shared memory 55 ( Step S4).

  If an unprocessed record remains in the memory list 80 (step S5, YES), the process returns to step S2, and if there is no unprocessed record (step S5, NO), the process ends.

12 and 13 are process flowcharts of the item processing unit 53 according to the first embodiment.
As described above, the processes in FIG. 12 and FIG. 13 (hereinafter sometimes referred to as FIG. 12 and the like) are cyclically executed under the management of the item processing schedule unit 52.

  In the processing example of FIG. 12 and the like, the item processing unit 53 first executes an initialization process for the item list 56 (step S11). For example, the processed flag 68 of all records in the item list 56 is set to “unprocessed”. Thereafter, the processes of steps S12 to S18 are repeatedly executed until NO in step S18 described later.

That is, (step S12) as the processing target record any record within the processed flag 68 is "raw" records in the item list 56, the device name 64 of the processing target record, and obtains the address 65 etc. (Step S12), the corresponding record in the shared memory 55 is searched using these, and the data is acquired (Step S13). That is, for example, a record whose device name 72 and address 73 are the same as the acquired device name 64 and address 65 is the corresponding record. Then, data 74 (data acquired from the allocation memory area) of the corresponding record is acquired (step S13). Here, the data 74 acquired in step S13 may be referred to as memory information 90.

  Based on the acquired memory information 90, the current state (for example, ON state or OFF state) relating to the item of the predetermined target record is determined, and the entire screen image 57 corresponding to the determination result is acquired (step S14). . For example, if it is determined that the current state is the ON state, the ON image No. of the record to be processed in the item list 56 is displayed. 67, the ON image No. The entire screen image 57 indicated by 67 is acquired. That is, the entire screen image for ON is acquired. Similarly, for example, when it is determined that the current state is the OFF state, the OFF image No. of the record to be processed in the item list 56 is displayed. 66, the OFF image No. An entire screen image 57 indicated by 66 is acquired. That is, the entire screen image for OFF is acquired.

  Then, an image of the corresponding area of the item to be processed is cut out from the entire screen image 57 acquired in step S14 (the part image is generated) (step S15). This cuts out an image of an area indicated by the coordinates 62 and the size 63 of the processing target record from the entire screen image 57 acquired in step S14. Then, the part image generated in step S15 is drawn in the corresponding area of the item to be processed (step S16). This is for drawing the part image generated in step S15 in the area indicated by the coordinates 62 and the size 63 of the processing target record.

  Finally, predetermined completion processing is executed (for example, the processed flag 68 of the processing target record is set to “processed”). Then, it is determined whether or not there is an unprocessed record in the item list 56 (step S18). If it remains (step S18, YES), the process returns to step S12, and if there is no unprocessed record (step S18). , NO) This process ends.

  As described above, according to the programmable controller system of the first embodiment, the support device 5, the programmable display device 1 and the like, creation of a screen (operation display screen; screen data) for the programmable display on the support device 5 side. Work time can be reduced. In particular, when screen data is created according to the entire image created by a designer or the like, the effort of the screen data creator is reduced. In addition, the entire image can be used effectively.

  Furthermore, when the design of the operation display screen is changed (however, as described above, it is basically assumed that the item type, arrangement, allocated memory, etc. are not changed), the entire screen image is simply replaced with a new design. Therefore, the burden of change work can be greatly reduced.

Next, Example 2 will be described below.
As described above (for example, as described in FIG. 9B and the like), in the case of the second embodiment, the data (screen data 22 and the like) and the processing operation in the programmable display 1 may be the same as those in the past. Here, since the item list 56 is almost the same as the screen data 22, the item list 56 ′ shown in FIG. 9B is regarded as the screen data 22, and the screen data creation processing in the support device 5 will be described below. explain.

Here, the description will be given with reference to FIGS. 4 and 5 again.
Also in the second embodiment, the developer's work itself on the support device 5 side may be considered as described with reference to FIGS. However, the generation processing of the screen data 22 corresponding to this work is different from that in the first embodiment.

  That is, as described with reference to FIG. 4, the user first designates a desired image portion (region to be converted into a part) by a mouse operation or the like (bold dotted rectangle shown). The coordinates and size of the designated area are stored in the coordinates 62 and the size 63 in the same manner as in the first embodiment, but in the second embodiment, an image of the designated area is further cut out (part image is cut out). ), An arbitrary unique identification ID (image No.) is assigned to the part image and registered. Basically, a part image is cut out from the entire ON and OFF screen images of the currently specified design, and an arbitrary unique image for each of the ON and OFF part images. No. Assign and memorize. Then, the image No. of the part image for ON generated and registered in this way is registered. ON image No. 67 'and the image No. of the part image for OFF is stored. OFF image No. 66 '.

  Thereafter, the work described in FIG. 5A and FIG. 5B is also performed, but the data addition processing to the screen data 22 corresponding to this work is as described above, and is not particularly described here. .

  The screen data 22 generated in this way has the same contents as the item list 56 'shown in FIG. 9B, for example. Then, the screen data 22 is downloaded and stored in the programmable display 1 together with the generated part image (and assigned with the image number). Thus, the programmable display 1 can display / update the operation display screen based on the screen data, the part image, and the like by the same processing operation as the conventional one.

Also, the part image can be registered on the support device 5 side and used for the screen data creation support work similar to the conventional one. That is, in the conventional to create screen data be placed in any position to select any item image to list the item image registered beforehand. In this example, screen data can be created by displaying a list of the registered part images, selecting an arbitrary part image, and placing it at an arbitrary position.

  The above-described processing is a specific example related to the second embodiment, and is not limited to this example. For example, in the support device 5, the part image may be cut out from each whole screen image, and a new item image may be generated / registered based on the clipped image. In this case, the screen data creation support function itself is the same as the conventional one, and the item image group including the new item image is displayed in a list, and an arbitrary item image can be selected and arranged at a desired position to a developer or the like. By doing this, screen data is created.

  As described above, the second embodiment is advantageous in that the programmable display can be used as it is, particularly when the present method is applied to an existing system. Further, the support device 5 can reduce the work load of screen data creation work and new item image generation / registration work.

  Note that the processing of the support device 5 in the second embodiment is also realized by the CPU (not shown) executing an animation program stored in advance in the storage unit (not shown) of the support device 5.

Here, functional block diagrams of the programmable display device 1 and the support device 5 of the first embodiment and the second embodiment are shown.
FIG. 14 is a functional block diagram of the programmable display device 1 and the support device 5 according to the first embodiment.

  In the example shown in the figure, the support device 5 includes a whole screen image storage unit 101 that stores a whole screen image, and a screen data generation support unit 102. The screen data generation support unit 102 generates screen data including at least designated area information for each item by designating an arbitrary area on the entire screen image for each item.

  The generated screen data is stored in the programmable display 1. Although this is downloaded to the programmable display 1 via a communication line, for example, it is not restricted to this example. The screen data may be stored in any portable recording medium, and the portable recording medium 1 may be connected to the programmable display 1 to store the screen data in the programmable display 1.

On the other hand, the programmable display device 1 includes a screen data storage unit 111, a part image generation unit 112, and an item display unit 113.
The screen data storage unit 111 stores the screen data generated by the support device 5 and the entire screen image. The entire screen image may be stored in advance in the programmable display 1 or may be downloaded from the support device 5 together with the screen data.

  For each item, the part image generation unit 112 generates a part image by cutting out the specified area portion related to the item from the entire screen image based on the specified area information of the upper screen data. The item display unit 113 displays, for each item, the part image generated by the part image generation unit 112 at a position indicated by the designated area information (displays an operation display screen). For example, the operation display screen is displayed based on the generated parts screen, for example, at any time or periodically (every time a parts screen is generated by the parts image generation unit 112).

Further, for example, a plurality of types of the whole screen image are stored in the whole screen image storage unit 101 or the screen data storage unit 111 according to each state. For example, an entire screen image for ON and an entire screen image for OFF are stored as an example. Then, the part image generation unit 112 generates a part image for each item from the entire screen image of the type corresponding to the current state related to the item. For example, if the current state is the switch ON state, a part image is generated from the entire screen image for ON. Similarly, if the current state is the switch OFF state, a part image is generated from the entire screen image for OFF.

Further, the programmable display 1 may further include an entire image changing unit 114 that changes an entire screen image of an arbitrary design stored in the screen data storage unit 111 to an entire screen image of another design. Good. This may simply replace the entire screen image stored in the screen data storage unit 111 with another design. In this case, after the change, the part image generation unit 112 generates a part image from the entire screen image of the other design. Therefore, the operation display screen displayed by the item display unit 113 is a screen whose design has been changed.

  Note that various parts image generation processing by the part image generation unit 112 may be executed in advance, and the generated part images (ON and OFF) may be stored. In this case, the subsequent processing of the programmable display device 1 may be substantially the same as in the second embodiment. In this case, a unique identification ID is assigned to the generated part image, and this identification ID is assigned to the OFF image No. 66 and ON image No. 67 is overwritten and stored. That is, in this case, the OFF image No. 66 and ON image No. With respect to 67, on the programmable display 1 side, the state is changed from the state in which the identification ID of the entire screen image is stored to the state in which the identification ID of the part image is stored.

FIG. 15 is a functional block diagram of the programmable display device 1 and the support device 5 according to the second embodiment.
The support device 5 according to the second embodiment includes an entire screen image storage unit 121 that stores an entire screen image, a part image generation unit 122, and a screen data generation support unit 123.

  The part image generation unit 122 designates an arbitrary area on the entire screen image for each item, and generates a part image by cutting out the designated area portion from the entire screen image. Then, the screen data generation support unit 123 generates screen data including a part image (image itself or identification ID of the part image) for each item and position information (coordinates, size, etc.) of the designated area.

  The programmable display device 1 according to the second embodiment includes a screen data storage unit 131 that stores the screen data generated by the screen data generation support unit 123. Furthermore, based on the screen data stored in the screen data storage unit 131, for each item, the item display unit 132 that displays the item using the part image of the item and the position information of the designated area. Have

  In the case of the second embodiment, the processing operation itself in the programmable display device 1 may be regarded as substantially the same as the conventional one. In the conventional support device, the user arranges an arbitrary item image at an arbitrary position, etc., thereby generating screen data including the item image and arrangement information (position information) of each item. And in the conventional programmable display, based on this screen data, the display which concerns on the item was performed for every item using the said item image and arrangement | positioning information of the item.

  Here, the part image of the present method is substantially the same as the conventional item image (of course, the generation method is different). Therefore, as described above, in the case of the second embodiment, the processing operation itself in the programmable display device 1 may be regarded as substantially the same as the conventional one.

  Further, for example, the screen whole image storage unit 121 stores a plurality of types of screen whole images corresponding to the respective states. For example, the part image generation unit 122 generates a plurality of types of part images from the plurality of types of entire screen images for each item. For example, the item display unit 132 displays for each item using a part image of a type corresponding to the current state related to the item. For example, taking a switch as an example, various part images for switch ON and switch OFF are generated. If the current state is the switch ON, display using the part image for switch ON is performed.

  Further, for example, the support device 5 according to the second embodiment includes a second whole image changing unit that changes a whole screen image of an arbitrary design stored in the whole screen image storage unit 121 to a whole screen image of another design. 124 may be further included. As a result, the screen data generation support unit 123 generates a part image from the entire screen image of the other design after the design change. Then, for example, screen data including this part image is downloaded and stored in the programmable display 1. Thereby, on the programmable display 1 side, the operation display screen is displayed using the part image after the design change, and thus the design of the operation display screen is changed.

  Note that the second whole image changing unit 124 may simply store additional whole screen images of the other designs in the whole screen image storage unit 121. Of course, an image identification ID is also assigned to the entire screen image of another design.

  After that, the editor function of the support device 5 presents not only the entire screen image of the arbitrary design (old design) but also the entire screen image of the other design (new design) to the user. To select the desired design. As a result, when the user selects the entire screen image of the new design, a part image corresponding to the new design is generated as described above, and this part image is operated on the programmable display 1 side. It will be used to display the display screen.

  In the case of the programmable display 1, the various functional units shown in FIGS. 14 and 15 are realized by the CPU 11 executing predetermined programs stored in the ROM 12 in advance. Further, in the case of the support device 5, the CPU (not shown) or the like is realized by executing a predetermined program stored in advance in the storage unit (not shown).

Finally, FIG. 16 shows an image of cutting out part images from the entire screen images.
In the above description, an example in which there are two types of on-screen and off-screen images for each design is used. However, the present invention is not limited to such an example. As a display form in the programmable display 1, there is a display form called “P2” other than the ON state and the OFF state. This P2 will not be described in particular (in short, it is not limited to two types but may be three or more types).

In the case of this example, for example, when the user designates an area related to an arbitrary item in FIG. 4, the part images are cut out from the three types of whole screen images, and the three types of part images shown in the figure (P2 image, ON Image, OFF image) is generated. Further, the screen data (item list 56) generated in the case of this example, for example, in the example of FIG. 9 (a), the illustrated OFF image N o. 66, ON image N o . 67 as well as a P2 image No. (not shown). Will also be added. When it is determined that the current status is P2 regarding an arbitrary item during operation in the programmable display device 1, a P2 image No. (not shown) is displayed. A part image is cut out and displayed from the entire screen image corresponding to.
