  Hereinafter, embodiments of the present invention will be described in detail.

Embodiment 1
An embodiment of the present invention will be described with reference to FIGS. First, an outline of the image creation system according to the present embodiment will be described with reference to FIG. FIG. 2 is a diagram showing an overview of the image creation system 200 according to the present embodiment. As illustrated, the image creation system 200 includes a personal computer (PC) 1, a programmable display 2, a PLC 3, and a communication terminal 4.

  A PC (display data creation device) 1 is a computer on which an OS (Operating System) is mounted, and is an image creation device that creates display data 31 that is data defining an image to be displayed on the programmable display 2. The display data 31 is an attribute that is information including at least one or more parts (display elements) to be displayed on the programmable display 2 and one or more attributes (position, size, shape, color, etc.) of the parts. Contains information. The PC 1 transmits the created display data 31 to the programmable display device 2.

  The PLC 3 is an external device connected to the programmable display 2 and transmits data collected by its own device to the programmable display 2. Moreover, PLC3 controls the operation | movement of the apparatus connected to PLC3 according to the control instruction | indication of the programmable display 2. FIG.

  The communication terminal 4 is a terminal that is communicatively connected to the programmable display device 2 and includes, for example, a terminal input unit that receives a user input operation, such as a tablet PC, a smartphone, and a notebook PC, and a terminal display unit that displays an image. It is. The communication terminal 4 becomes an operation terminal of the programmable display 2 when the programmable display 2 changes the attribute of the component. The connection between the programmable display 2 and the communication terminal 4 and the specific function of the communication terminal 4 as an operation terminal of the programmable display 2 will be described in detail later.

  The programmable display (first programmable display, second programmable display) 2 is an HMI (Human Machine Interface) device that displays an image corresponding to the display data 31 received from the PC 1. The programmable display 2 can reflect various data received from the PLC 3 and data generated inside the programmable display 2 in an image corresponding to the display data 31. For example, the programmable display 2 can display the component by reflecting the numerical value of the temperature received from the PLC 3 as the value indicated by the needle of the meter (component) included in the display data 31.

  Further, the programmable display 2 can change the attribute of one or more parts included in the display data 31 and display the parts in a state in which the change is reflected. Specifically, the programmable display 2 is information corresponding to attribute information that is permitted to be changed among the component attribute information included in the display data 31, and can be changed (updated) from the programmable display 2. Variable attribute information 81 is created. Moreover, the programmable display device 2 updates the variable attribute information 81 based on data from the communication terminal 4. Then, an image (display image) to be displayed on the entire display screen is created and displayed using the display data 31 and the variable attribute information 81. Thereby, the attribute information (change is permitted) of the parts in the display data 31 can be changed not by the PC 1 that created the display data 31 but by the programmable display 2 (and the communication terminal 4). That is, the programmable display device 2 can change the position, size, shape, color, and the like of the component with its own device.

  Next, the main configuration of each apparatus described with reference to FIG. 2 will be described with reference to FIG. FIG. 1 is a block diagram illustrating configurations of the PC 1, the programmable display 2, and the communication terminal 4 according to the first embodiment. The programmable display 2 is communicably connected to the PC 1, PLC 3, and communication terminal 4.

  The PC 1 includes an input device 10, a data creation unit 20, a storage unit 30, a transmission unit 40 that transmits display data 31 to the programmable display 2, and a monitor 11 that displays a GUI (Graphical User Interface). I have. In addition to this, the PC 1 may include a configuration generally provided in a general-purpose computer, such as a CPU (Central Processing Unit), a memory, a volatile or nonvolatile storage device, and a communication interface.

  The input device 10 receives user input operations. The input device 10 receives an input operation for creating display data 31 in a data creation unit 20 described later.

  The data creation unit 20 creates display data 31. Here, the display data 31 includes at least one or more parts to be displayed on the display screen of the programmable display device 2 and attribute information indicating attributes of the respective parts. Here, the “component” is an object having a specific function (such as a switch, lamp, meter, etc. that the programmable display 2 performs a predetermined control according to a user operation) or an object that simply displays predetermined data. (Image, label, text box, etc.). In addition to the component image and attribute information, the display data 31 includes a background image displayed on the background of the component image described above, various setting data for the entire image (component image and background image) displayed on the programmable display 2, A script program describing processing to be executed by the programmable display device 2 may be included.

  The data creation unit 20 creates the display data 31 described above in response to a user input operation received via the input device 10. When a user input operation indicating storage of the created display data 31 is accepted via the input device 10, the display data 31 is stored in the storage unit 30. More specifically, the data creation unit 20 directly stores the value of each attribute for each piece of attribute information included in the display data 31 in response to a user input operation on the input device 10 (directly specifies a value). ) Or variable attribute information 81 is set. The “value” referred to here is not necessarily a numerical value. For example, when the component is a label, it may be text data such as a word displayed on the label, or any other form of information. Hereinafter, the setting of directly storing the value of each attribute (directly specifying the value) or referring to the variable attribute information 81 is referred to as “reference setting”.

  When the setting value is directly stored in the attribute information (when the reference setting is directly specified), the data creation unit 20 causes the user to input the setting value for each attribute of each component included in the display data 31. Note that the data creation unit 20 may use standard attribute values (size, color, etc.) stored in the storage unit 30 or the like as the value of each attribute instead of allowing the user to perform the above input. On the other hand, when the variable attribute information 81 is referred to for the setting value of each attribute of the component (when the reference setting is a reference), the data creation unit 20 performs the user's input operation or the data creation unit 20 or the storage. Based on the information stored in advance by the unit 30, the address of the variable attribute information 81 to be referenced is specified, and the address is set as the value of each attribute of the attribute information.

  Further, when receiving an input operation for instructing to transfer the display data 31 to the programmable display 2 via the input device 10, the data creation unit 20 transmits the display data 31 stored in the storage unit 30 to the transmission unit. 40 to the programmable display 2. At this time, the data creation unit 20 sets a predetermined value for each attribute of the attribute information for the attribute information whose reference setting is the reference among the attribute information of each component of the display data 31 (initial setting). Set value) and the initial set value are transmitted to the programmable display 2 together with the display data 31.

  The storage unit 30 stores the display data 31 created by the data creation unit 20. Although not shown, the storage unit 30 is used for the data creation unit 20 to create the display data 31 (for example, to present to the user for the creation of the display data 31 and to combine as a display element of the display data 31). ) Image data of part images and background images may also be stored. In addition, the storage unit 30 may store a value set as an initial setting value for each attribute. Further, the storage unit 30 may be a storage device built in the PC 1 such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive), an SD memory card, or a USB (Universal Serial Bus) flash. It may be an external storage device accessible via a predetermined interface or drive of the PC 1 such as a memory and a DVD (Digital Versatile Disc).

  The transmission unit 40 transfers the display data 31 and the initial setting value to the programmable display 2 in accordance with an instruction from the data creation unit 20.

  Next, the main part structure of the programmable display 2 is demonstrated. The programmable display 2 is a computer that receives an instruction operation of a user and displays an image including various components to be displayed, and is an HMI (Human Machine Interface) device. The programmable display device 2 creates a display function for displaying an image in accordance with display data 31 received from the PC 1, an operation function for accepting a user input to a screen displaying the image (display panel 61), and variable attribute information 81. And an attribute change function for changing.

  In order to realize these functions, the programmable display device 2 includes a receiving unit 50, an I / F 90, a display panel 61 (display unit), a touch panel 60, a control unit 70, and a storage unit 30. Yes. In the present embodiment, the programmable display 2 is a device including the touch panel 60 and the display panel 61, but the programmable display 2 is not limited to such a device form. For example, you may comprise the programmable display 2 by connecting the display containing the touch panel 60 and the display panel 61 to the apparatus which is not equipped with the touch panel 60 and the display panel 61 like an industrial computer.

  The receiving unit 50 communicates with the PC 1 and receives the display data 31 and the initial setting value from the PC 1. The receiving unit 50 transmits the received display data 31 and the initial setting value to the control unit 70. The I / F 90 communicates with the PLC 3. The display panel 61 is a display unit that displays an image, and is a flat display device such as a liquid crystal display. The touch panel 60 receives a touch on the display panel 61. The touch panel 60 is provided so as to overlap the display panel 61. In addition, the programmable display 2 may be provided with an input device such as a keyboard separately instead of the touch panel 60 and may accept input from the input device.

  The control unit 70 controls the programmable display device 2 in an integrated manner. The control unit 70 performs control according to the user's input operation on the image indicated by the touch on the touch panel 60 according to an operation mode described later. In addition, the control unit 70 stores the display data 31 and the initial setting value received from the receiving unit 50 in a first storage area (described later) of the storage unit 80. Further, the control unit 70 acquires data obtained from the device controlled by the PLC 3 by communicating with the PLC 3, and the setting (address setting) indicated by the data and the attribute information of the parts included in the display data 31. Based on the above, the display state of the component image is changed.

  Furthermore, the control unit 70 can change the attributes of one or more parts included in the display data 31. The control unit 70 includes a variable attribute information creation unit 71, a mode switching unit 72, and a display control unit 73 in order to make the change.

  The mode switching unit 72 switches the operation mode of the programmable display device 2. In the present embodiment, there are two types of operation modes of the programmable display 2: “normal mode” and “change mode”. The mode switching unit 72 switches the operation mode to the change mode when the touch panel 60 receives an input operation instructing a change to the change mode. Further, the mode switching unit 72 switches the operation mode to the normal mode in which the programmable display device 2 performs a normal driving operation when the touch panel 60 receives an input operation instructing the change to the normal mode. Further, the mode switching unit 72 stores a mode selection flag 82 that is information indicating the mode after switching in a second storage area (described later) of the storage unit 80.

  Here, the “normal mode” is a mode for realizing the display function and the operation function of the programmable display device 2. In the normal mode, when the touch panel 60 receives an input operation, the control unit 70 determines that the input operation is an operation on a component. Such operations include, for example, pressing a button, switching a switch, setting a temperature, setting a value from the programmable display 2 to be performed by an external device via the PLC 3, or setting the external device, and switching a meter display. The display change is defined to be performed when a part is selected in advance.

  On the other hand, the “change mode” is a mode for realizing the attribute change function of the programmable display device 2. In other words, the change mode can be said to be a mode for changing the screen layout or screen setting of the programmable display device 2. In the change mode, when the touch panel 60 receives an input operation, an operation for selecting a component whose attribute information (or change information is further changed), or an operation for changing the attribute information (or change information) of the currently selected component, to decide.

  The variable attribute information creation unit 71 creates and changes the variable attribute information 81. The variable attribute information creation unit 71 checks the second storage area of the storage unit 80 when the power of the programmable display 2 is turned on. If the variable attribute information 81 does not exist, the variable attribute information creation unit 71 stores the second storage area in the storage unit 80. Variable attribute information 81 is created based on the stored initial setting value. In addition, the variable attribute information creation unit 71 receives change information obtained by changing the variable attribute information 81 from the communication terminal 4, and updates the variable attribute information 81 based on the change information. Note that the variable attribute information creation unit 71 can change at least setting values that define attributes related to appearance when displaying an image of a component on the display panel 61, such as the arrangement, size, and display style of the component. It is desirable. By changing the appearance when the component is displayed on the display panel 61, the user of the programmable display device 2 looks the layout, size, color, etc. of the component defined by the display data 31 created by the PC 1 This is because it can be changed to make it easier to use, improving convenience.

  The display control unit 73 displays an image on the display panel 61 based on the display data 31 and variable attribute information 81 stored in the storage unit 80. More specifically, the display control unit 73 displays a part specified to be displayed by the display data 31 in a display format (position, size, color, And shape).

  The storage unit 80 stores display data 31, initial setting values, variable attribute information 81, a mode selection flag 82, and selected component specifying information 83. The storage unit 80 may be a storage device built in the programmable display 2 or an external storage device connected to the programmable display 2 via a predetermined interface. The storage unit 80 includes a first storage area (first storage part) and a second storage area (second storage part). Hereinafter, the storage unit 80, the display data 31 stored in the storage unit 80, and the variable attribute information 81 will be described in detail with reference to FIG.

  FIG. 3 is a diagram illustrating the configuration of the storage unit 80 and the structure of various data stored in the storage unit 80. As illustrated, the storage unit 80 includes a first storage area and a second storage area. The first storage area is a storage area in which data once stored in the area can only be read. In other words, the first storage area is a fixed data area for storing fixed data that cannot be rewritten by the programmable display device 2. In the first storage area, display data 31 received by the receiving unit 50 from the PC 1 and an initial set value are stored. On the other hand, the second storage area is a storage area where data can be freely read and written. In other words, the second storage area is a variable data area rewritable by the programmable display device 2. In the second storage area, variable attribute information 81 created by the variable attribute information creation unit 71, a mode selection flag 82, and selected component specifying information 83 are stored.

  Next, the attribute information, variable attribute information 81, mode selection flag 82, and selected component specifying information 83 of the display data 31 will be described in detail. As described above, the display data 31 includes attribute information (“part # 1 attribute information”, “part # 2 attribute information”,... “Part #N attribute information”) corresponding to each part included in the data. Contains. As shown in the figure, the attribute information is information in which various pieces of information indicating the component attributes such as the shape, position, size, and color of the component are collected.

  Further, the attribute information includes values or types of various attributes that are directly specified by the attribute information without referring to the variable attribute information 81 (“direct specification” of “part # 2 attribute information”). ”), Or a reference setting indicating whether to refer to a value described in the variable attribute information 81 (“ reference ”of“ attribute information of part # 1 ”) is stored. Thus, by including the reference setting in the attribute information, whether or not to refer to the variable attribute information 81 whose attribute information has been changed can be set for each component. When the reference setting is “direct specification”, the value of each attribute of the part (shape, position, size, color in FIG. 3) is directly stored in the attribute information. On the other hand, when the reference setting is “reference”, the attribute information refers to the value of the same attribute in the variable attribute information 81 corresponding to the attribute information (the component with which the attribute information is associated) instead of the value of each attribute. An address (information storage address) is stored. In addition, in the attribute information whose reference setting is “reference” like the “shape” attribute of the component # 1, some attribute values may be stored in the attribute information in the same manner as the direct designation.

  The variable attribute information 81 is information that stores a value of attribute information in which the reference setting is set to “reference” among the attribute information described above. Here, the variable attribute information 81 is changeable information stored in the data variable area. Like the attribute information, the variable attribute information 81 is associated with each component included in the display data 31. Note that the variable attribute information 81 may store the variable attribute information 81 only for some attributes (position, size, and color in the case of the variable attribute information 81 of the component # 1 in FIG. 3) of the attribute information. I do not care. In this case, for values of attributes not stored in the variable attribute information 81, values stored in the attribute information may be referred to. Further, the variable attribute information 81 may include a flag (change flag) indicating whether the value of each attribute has been changed from the initial setting value (changed) or not (no change). Taking the variable attribute information 81 of the part # 1 in FIG. 3 as an example, in the variable attribute information 81, the position and size attributes of the three types of attributes of position, size, and color are changed from the initial setting values. It is shown that the color has not been changed from the initial setting value.

  The mode selection flag 82 indicates a flag indicating the current operation mode of the programmable display device 2. The mode selection flag 82 is rewritten by the mode switching unit 72. The mode selection flag 82 changes the process control depending on the operation mode when the display screen 61 of the display panel 61 is updated (screen refresh) or when an input operation is performed on the input device 10. In such a case, the control unit 70 refers to it. The selected part specifying information 83 is information for specifying the part currently selected in the change mode. The format of the selected component specifying information 83 is not particularly limited as long as the selected component specifying information 83 is information that can uniquely specify a component such as the name and ID of the selected component.

  The display control unit 73 of the control unit 70 reads the display data 31 and the variable attribute information 81 every time the display panel 61 is updated (refreshed) in both the normal mode and the change mode, and reflects these information. An image (display image) to be displayed on the entire display screen of the display panel 61 is created and output to the display panel 61. More specifically, the display control unit 73 first reads the display data 31 in the first storage area in accordance with the update timing of the display panel 61. As described above, the display data 31 includes attribute information of each component, and the display control unit 73 first confirms the reference setting of each attribute information.

  For the attribute information whose reference setting is “direct designation”, the display control unit 73 reflects the setting value set in the attribute information on each attribute of the component and displays it as a part of the display image. Specifically, referring to the example of FIG. 3, for example, the control unit 70 reflects the value directly set in the attribute information of the component # 2 in the creation of the display image for the component # 2 whose reference setting is directly specified. Let That is, the part # 2 has a shape: label, position: X (coordinate) = 20, Y (coordinate) = 40, size: W (width) = 32, H (height) = 32, color: BLUE in the display image. Will be displayed.

  On the other hand, for the attribute information whose reference setting is “reference”, the display control unit 73 reads the information storage address set in each attribute of the attribute information, and stores the variable attribute information 81 of the designation destination of the information storage address. The value is read out, and the value is reflected in each attribute of the component and displayed as a part of the display image. Specifically, in the example of FIG. 3, the component # 1 whose reference setting indicates a reference has a shape: square button, position: X (coordinate) = 10, Y (coordinate) = 20, size: W in the display image. (Width) = 32, H (height) = 32, color: RED.

  As described above, the variable attribute information 81 is information that is changed at any time in the change mode. The display control unit 73 always refers to the latest variable attribute information 81 every time the display panel 61 is updated. Therefore, when the variable attribute information creation unit 71 changes the variable attribute information 81, the change is almost simultaneously displayed on the display image (strictly speaking, immediately after the changed variable attribute information 81 is stored in the second storage area). This is reflected at the display image creation timing). Therefore, the user can check the attribute information changed by the input operation on the display screen of the display panel 61 almost simultaneously in the change mode.

  Next, the PLC 3 will be described. The PLC 3 is a control device that controls a target system to be controlled. The target system is configured by various devices (output devices such as motors and input devices such as sensors) arranged in a production line. The PLC 3 is a control device that controls the target system in accordance with a logic program that defines the operation of the target system. The PLC 3 is communicably connected to the programmable display device 2.

  The logic program defines a sequence of operations such as a series of operations of the target system to be controlled by the PLC 3 and data output to the programmable display 2 by a ladder program or the like, and is created by the user. By executing the logic program, the PLC 3 monitors and controls the operation of the target system and collects data from the target system according to the procedure specified by the logic program. The collected data is output to the programmable display 2.

  Next, the configuration of the communication terminal 4 will be described. As illustrated, the communication terminal 4 includes a terminal communication unit 110, a terminal input unit 120, a terminal display unit 140, and a terminal control unit 130.

  The terminal communication unit 110 performs communication with the programmable display device 2. Specifically, the terminal communication unit 110 receives the variable attribute information 81 from the programmable display device 2 and sends it to the terminal control unit 130. In addition, the terminal communication unit 110 transmits change information, which is variable attribute information 81 whose value has been changed by the terminal control unit 130, to the programmable display 2.

  The terminal input unit 120 is an input device in the communication terminal 4. Specifically, like the touch panel 60 of the programmable display device 2, the terminal input unit 120 is formed integrally with the terminal display unit 140 and accepts a touch operation on the terminal display unit 140 of the communication terminal 4 as an input operation. Is desirable. The terminal display unit 140 is a display device that displays an image according to the control of the terminal control unit 130. The terminal display unit 140 is realized by a liquid crystal panel, for example.

  The terminal control unit 130 controls the communication terminal 4 in an integrated manner. The terminal control unit 130 establishes a communication connection with the programmable display 2 according to the input operation received by the terminal input unit 120. More specifically, the terminal control unit 130 includes an attribute list creation unit (attribute information list creation unit) 131 and a change information creation unit 132. The attribute list creation unit 131 causes the terminal display unit 140 to display the variable attribute information 81 received from the programmable display device 2 via the terminal communication unit 110 as an attribute information list in a format that can be confirmed by the user, such as a list format. The change information creation unit 132 creates change information obtained by changing the variable attribute information 81 received from the programmable display device 2 according to an input operation on the terminal input unit 120, and displays the change information via the terminal communication unit 110. To device 2.

  Next, an input operation for changing the variable attribute information 81 of the component displayed on the display panel 61 of the programmable display 2 using the communication terminal 4, and the display panel 61 and the terminal display corresponding to the input operation The screen transition of the unit 140 will be described with reference to FIG. FIG. 4 is a diagram illustrating an image example when the variable attribute information 81 of the component displayed on the programmable display 2 is changed using the communication terminal 4. More specifically, (a) in FIG. 4 is a component for changing the variable attribute information 81 in the programmable display 2 when (b) in FIG. 4 is established when the communication connection between the programmable display 2 and the communication terminal 4 is established. 4C shows an example of an image when a part of the variable attribute information 81 is changed in the communication terminal 4.

  First, the programmable display 2 and the communication terminal 4 establish communication with each other as shown in FIG. Operation and processing for establishing communication are not particularly limited. For example, when a touch operation is performed on a specific button (connection button) displayed on the display panel 61 of the programmable display 2 in the normal mode or the change mode. Alternatively, the touch panel 60 may receive the touch operation and transmit it to the control unit 70, and the control unit 70 may transmit a near field communication request to the nearby communication terminal 4 in response to the operation. When the terminal control unit 130 of the communication terminal 4 receives the request via the terminal communication unit 110, the terminal control unit 130 displays a button (Connect to HMI) and the like as shown in FIG. Whether or not to approve the connection request may be selected. When an operation for approving the request (such as an operation of touching the above button) is performed on the terminal input unit 120, the terminal control unit 130 approves the request to the programmable display device 2 via the terminal communication unit 110. May be established to establish a communication connection between the programmable display 2 and the communication terminal 4.

  In the state in which the communication connection between the programmable display 2 and the communication terminal 4 is established and the programmable display 2 is in the change mode, the display image is included in the programmable display 2 as shown in FIG. When any one of the parts to be selected is selected, the variable attribute information creation unit 71 stores the selected part specifying information 83 of the selected part in the storage unit 80. Further, the variable attribute information creation unit 71 reads the variable attribute information 81 of the selected part from the storage unit 80 and transmits it to the communication terminal 4 via the communication unit 100. At this time, the variable attribute information creation unit 71 may not send the information indicating the change flag of each attribute of the variable attribute information 81 to the communication terminal 4. Upon receiving the variable attribute information 81, the attribute list creation unit 131 of the terminal control unit 130 of the communication terminal 4 displays the variable attribute information 81 on the terminal display unit 140 in a format that can be confirmed by the user and that can change the attribute value, such as a list format. Let For example, as shown in FIG. 4B, attributes such as Pos (position), Size (size), Color (color), Label (label), and the value of the attribute may be displayed in a list together with the part ID.

  In addition, as a specific example of the operation of selecting a component on the programmable display 2, in addition to the operation of touching the component as illustrated, the ID attached to the component and the name of the component are displayed on the programmable display 2 or communication. You may use the method of selecting from the list image displayed on the terminal 4, the method of directly inputting ID and name of components selected with the communication terminal 4, etc.

  Moreover, when operation which selects components in the programmable display 2 or the communication terminal 4 is performed, the display control part 73 differs in the display form of the said components from before selection so that the components in selection can be understood easily by a user. You may change to a display form. For example, as shown in (b) to (c) of FIG. 4, highlighting may be performed so that the frame line of the selected component is displayed thickly. As a result, the user can easily determine the selected component.

  Further, as shown in FIGS. 4B to 4C, the display control unit 73 displays the entire display image different from the normal mode when the operation mode of the programmable display device 2 is the change mode. You may display on the display panel 61 in a format. For example, as shown in (b) to (c) of FIG. 4, during the change mode, highlighting such as displaying the entire display image in a frame may be performed. Thereby, the user can easily determine whether the programmable display 2 is currently in the normal mode or the change mode.

  Here, when the user selects a setting value of one of the attributes via the terminal input unit 120 and performs an operation of changing the setting value, the changed setting value is displayed on the programmable display 2. Are reflected almost simultaneously. For example, the user selects a set value of the component size width (20 in the figure) at the communication terminal 4 as shown in FIG. 4B, and the set value as shown in FIG. 4C. When the operation to be increased to 30 is performed, the terminal input unit 120 receives the operation and transmits the operation to the terminal control unit 130, and the change information creation unit 132 of the terminal control unit 130 includes the variable attribute information 81 according to the operation. Change information in which the value of the size width is changed to 30 is created and transmitted to the programmable display device 2. When the variable attribute information creating unit 71 of the control unit 70 of the programmable display 2 receives the value, the variable attribute information 81 is overwritten with the attribute value indicated by the change information. That is, the value indicating the size width in the variable attribute information 81 is updated from 20 to 30. At this time, if the updated attribute change flag is “no change”, the variable attribute information creation unit 71 also updates the change flag to “changed”. Then, the display control unit 73 refers to the variable attribute information 81 at the update timing of the display panel 61. Thereby, the value of the width of the size updated as described above is reflected in the corresponding component in the display image.

  The change information creation unit 132 creates, as change information, information indicating only the changed attribute and the changed value of the attribute among the received attributes of the variable attribute information 81, and transmits the change information to the programmable display device 2. May be. In the example of FIG. 4, information indicating that the value of the attribute “size width” has been changed to 30 among the variable attribute information 81 may be created as change information and transmitted to the programmable display device 2.

  Moreover, the communication terminal 4 does not need to receive the variable attribute information 81 from the programmable display device 2 when the component whose attribute can be changed from the communication terminal 4 and the attribute of the component are determined in advance. In this case, the attribute list creation unit 131 of the terminal control unit 130 causes the terminal display unit 140 to display a list of predetermined attributes of predetermined parts, and allows the user to make the above-described determination via the terminal input unit 120. Let the attribute value be entered. And what is necessary is just to transmit the input value to the programmable display 2 as change information. Thereby, since it is not necessary to transmit the variable attribute information 81 from the programmable display 2 to the communication terminal 4, the amount of communication can be reduced.

  Finally, the programmable display device 2 and the communication terminal 4 change the variable attribute information 81, and create and display a display image in which the changed variable attribute information 81 is reflected on the parts of the display data 31 (image creation processing) ) Will be described with reference to FIG. FIG. 5 is a flowchart showing a flow of image creation processing performed by the programmable display device 2 and the communication terminal 4. In addition, below, it demonstrates as that the communication connection of the programmable display 2 and the communication terminal 4 demonstrated using (a) of FIG. 4 is established previously.

  When the programmable display 2 is turned on, the variable attribute information creation unit 71 of the control unit 70 first checks whether the variable attribute information 81 exists in the second storage area of the storage unit 80. When the variable attribute information 81 does not exist, the variable attribute information creation unit 71 creates the variable attribute information 81 from the initial setting value stored in the first storage area of the storage unit 80.

  Then, the programmable display device 2 is activated in the normal mode, and displays an image corresponding to the display data 31 and the variable attribute information 81 stored in the storage unit 80 on the display panel 61 (S10). More specifically, for each part included in the display data 31, the display control unit 73 sets the attribute setting value indicated by the attribute information when the reference setting of the attribute information of the part is set to “direct designation”. The attribute information whose reference setting is set to “reference” is displayed based on the setting value stored in the variable attribute information 81.

  The control unit 70 is in the normal mode until the operation (change operation) for instructing the change to the change mode is received on the touch panel 60 (NO in S12), that is, while the programmable display 2 is driven in the normal mode. Works to realize display function and operation function. Here, when the operation (change operation) instructing the change to the change mode is accepted on the touch panel 60 (YES in S12), the mode switching unit 72 of the control unit 70 causes the operation mode of the programmable display device 2 to correspond to the operation. Is switched to the change mode (S14), and the mode selection flag 82 stored in the storage unit 80 is switched to a flag indicating the change mode.

  When switched to the change mode, the control unit 70 of the programmable display device 2 works to realize the attribute change function. When an operation for selecting a component is performed on the touch panel 60 in the change mode (YES in S16), the variable attribute information creation unit 71 receives the operation and stores the selected component specifying information 83 of the selected component in the storage unit 80. Remember me. When an operation for selecting a part is performed, the display control unit 73 may change the display form of the part to a display form different from that before selection so that the user can easily understand the selected part (S18). ). For example, the selected part may be displayed blinking, the color may be changed, or the frame may be enclosed.

  Furthermore, the variable attribute information creation unit 71 reads the variable attribute information 81 of the selected part from the storage unit 80 and transmits it to the communication terminal 4 (S20). Upon receiving the variable attribute information 81 (S40), the terminal communication unit 110 of the communication terminal 4 transmits the variable attribute information 81 to the terminal control unit 130. The attribute list creation unit 131 of the terminal control unit 130 creates a list of variable attribute information 81 and displays it on the terminal display unit 140 (S42), and waits until a user input operation is performed on the terminal input unit 120 (S44). NO). Then, when an input operation (for example, change of position coordinates, change of size or color, etc.) for changing any attribute value of the variable attribute information 81 is performed in the terminal input unit 120 (YES in S44). The change information creation unit 132 of the terminal control unit 130 creates change information reflecting the change in the variable attribute information 81 (S45), and transmits the change information to the programmable display device 2 via the terminal communication unit 110 (S46). When the communication unit 100 of the programmable display 2 receives the change information (S22), the communication unit 100 transmits the change information to the control unit 70, and the variable attribute information creation unit 71 of the control unit 70 stores the storage unit 80 with the value indicated by the change information. The variable attribute information 81 is updated (S24). Here, as described above, the display control unit 73 of the control unit 70 refers to the display data 31 and the variable attribute information 81 every time the display screen of the display panel 61 is updated. Therefore, when the variable attribute information 81 updated by the variable attribute information creation unit 71 is stored in the storage unit 80, a component reflecting the value of the variable attribute information 81 is displayed on the display panel 61 almost simultaneously. (S24).

  Such updating of the variable attribute information 81 using the communication terminal 4 is repeated until an input operation for instructing the end of the change mode (instructing the change to the normal mode) is performed on the touch panel 60 (NO in S26). ). When an input operation for instructing the end of the change mode (mode change to the normal mode) is performed on the touch panel 60 (YES in S26), the mode switching unit 72 of the control unit 70 displays a programmable display according to the input operation. The operation mode of the device 2 is switched from the change mode to the normal mode (S28), and the mode selection flag 82 of the storage unit 80 is switched to a flag indicating the normal mode.

  According to the above processing, since the variable attribute information 81 is updated according to the change information created in the communication terminal 4, it is included in the variable attribute information 81 in order to update the variable attribute information 81 in the programmable display 2. It is no longer necessary to display a list of attribute values. Therefore, the display image of the programmable display device 2 is not hidden by the list or the like. Therefore, since the user can change the variable attribute information 81, that is, the attribute of the component on the communication terminal 4 while viewing the display image of the programmable display device 2, the user can easily perform the operation related to the change. There is an effect. Moreover, according to the above process, the terminal display part 140 of the communication terminal 4 should just display the list of the value of an attribute instead of the whole display image of the programmable display 2. FIG. Therefore, even if the communication terminal 4 is a terminal whose display screen size is limited, a list of attribute values can be displayed to the user with high visibility. The terminal input unit 120 of the communication terminal 4 only needs to have a sensitivity that allows the user to specify an attribute value in the list. For example, it is difficult for the terminal input unit 120 to specify fine coordinates. Even in the case of an input device (for example, a touch panel with low sensitivity), an attribute value can be input without impairing user convenience.

  The acceptance of the operation for instructing the change mode and the acceptance of the operation for instructing the end of the change mode (change to the normal mode) may be performed by the programmable display 2 or the communication terminal 4. You may go. That is, when the terminal input unit 120 of the communication terminal 4 receives an input operation that triggers the determination of S12 and S26 and the terminal control unit 130 receives information indicating the input operation, the terminal communication unit 110 displays the information in a programmable manner. It may be transmitted to the device 2. And the control part 70 of the programmable display 2 may receive the information which shows the said input operation via the communication part 100, and may determine whether the mode switching part 72 switches the mode using the said information.

  When the programmable display 2 performs an operation for instructing to change to the change mode and to end the change mode, the mode switching unit 72 is a specific address area in an internal memory (not shown) provided in the programmable display 2. The mode may be switched by rewriting the value at. The writing of the value may be performed by operating a button on the image displayed on the programmable display 2.

  Further, the mode switching unit 72 may switch the mode according to the procedure specified in the above-described script program created by the user. If the script program is used, the mode can be switched in a desired procedure defined by the user. For example, when an internal flag that is turned on when an attribute change request is made from the communication terminal 4 and an ID that is transmitted from the communication terminal 4 when the attribute change request is made, the mode switching unit 72 changes the state of the internal flag. The monitored ID and the transmitted ID (transmission ID) are collated with the ID (memory ID) stored in the programmable display 2. The mode switching unit 72 can turn on the mode selection flag 82 after confirming that the internal flag is turned on and confirming that the transmission ID matches the stored ID. The mode switching unit 72 can also shift to the change mode when a bit in a specific area of the internal memory of the PLC 3 is set.

[Embodiment 2]
The data creation unit 20 of the PC 1 according to the present invention may create the variable attribute information 81 in addition to the creation of the display data 31 and transfer the display data 31 and the variable attribute information 81 to the programmable display 2. Hereinafter, a second embodiment of the present invention will be described with reference to FIGS. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted.

  FIG. 6 is a diagram illustrating data transmission / reception between the PC 1 and the programmable displays 2A to 2C in the image creation system 300 according to the present embodiment. The programmable displays 2A to 2C have the same functions and configurations as the programmable display 2 in the first embodiment.

  In the present embodiment, the data creation unit 20 of the PC 1 creates variable attribute information 81A to 81C used in each of the programmable displays 2A to 2C separately from the attribute information of the display data 31 in response to an input operation on the input device 10. To do. In other words, the data creation unit 20 includes display data 31 including attribute information in which values commonly used by the programmable displays 2A to 2C are set, and variable attributes including values set separately for the programmable displays 2A to 2C. Information 81A-81C is created. Then, the data creation unit 20 transmits the display data 31 and the variable attribute information 81A to 81C to the programmable display 2 via the transmission unit 40. The control unit 70 of the programmable display device 2 receives this via the receiving unit 50, the display data 31 goes to the first storage area of the storage unit 80, and the variable attribute information 81 </ b> A to 81 </ b> C goes to the second storage area of the storage unit 80. Remember me. The display controllers 73 of the programmable displays 2A to 2C create display images using the variable attribute information 81A to 81C stored in the second storage area and the display data 31, respectively, and display them on the display panel 61.

  FIG. 7 is a diagram illustrating an example of images displayed on the programmable displays 2A to 2C by transmission and reception of data illustrated in FIG. As shown in FIGS. 6 and 7, the variable attribute information 81 </ b> A to 81 </ b> C in which the PC 1 has changed the label language (TANK # 1 to # 3) of the label (component) 1000 in the display image defined by the display data 31. Are generated and transmitted to the programmable displays 2A to 2C, respectively, the programmable displays 2A to 2C display labels (TANK # 1 to # 3) that differ only in the text of the label 1000, respectively.

  In addition, the creation method of the variable attribute information 81A to 81C in the data creation unit 20 is not particularly limited. For example, the data creation unit 20 causes the monitor 11 to display the setting value input image of the variable attribute information for a component whose reference setting is set to “reference” among the components included in the display data 31, and via the input device 10. You may make a user input the setting value of each attribute. When an input operation for creating variable attribute information with the input set value is performed on the input device 10, the variable attribute information 81A to 81C may be created with the set value. The data creation unit 20 stores the created variable attribute information 81A to 81C in the storage unit 30, and instructs the input device 10 to transmit the display data 31 (or at least one of the variable attribute information 81A to 81C). When the input operation is performed, the variable attribute information 81A to 81C (or only the variable attribute information 81A to 81C for which transmission is specified) may be transmitted to the programmable display 2 together with the display data 31.

  In the present embodiment, since the PC 1 creates the variable attribute information 81 in advance and transmits it to the programmable display 2, the variable attribute information creation unit 71 of the programmable display 2 has the variable attribute information when the programmable display 2 is turned on. Information 81 is not created. Therefore, the PC 1 does not have to create an initial setting value and transmit it to the programmable display device 2.

[Embodiment 3]
In the image creation system according to the present invention, variable attribute information (or change information obtained by changing variable attribute information) transmitted from a programmable display to a communication terminal may be transferred to another programmable display. . Further, at the time of the transfer, only the value of the attribute whose change flag is “changed” among the variable attribute information (or change information obtained by changing the variable attribute information), that is, the value changed from the initial setting value is transferred. May be. Hereinafter, a third embodiment of the present invention will be described with reference to FIG.

  FIG. 8 is a diagram illustrating data transmission / reception among the PC 1, the programmable display 2, and the communication terminal 4 in the image creation system 400. As shown to (a) of FIG. 8, programmable display device 2A-2C is displaying the display image based on the display data 31 and the variable attribute information 81A-81C, respectively. More specifically, the variable attribute information 81A to 81C is information in which the wording (TANK # 1 to # 3) of the label 1000 is changed as an attribute value, and the variable attribute information 81A further includes the shape of the button 2000. The information has been changed to a square. Therefore, as shown in the figure, the programmable display 2A displays a square button 2000 and a label 1000 described as “TANK # 1”. Further, the programmable display 2B displays a label 1000 on which “TANK # 2” is written. Further, the programmable display 2C displays a label 1000 on which “TANK # 3” is described.

  Here, when the communication terminal 4 receives the variable attribute information 81A from the programmable display 2A, the attribute list creation unit 131 of the terminal control unit 130 of the communication terminal 4 causes the terminal display unit 140 to display a list of the variable attribute information 81A. The communication terminal 4 according to the present embodiment is configured to transmit the variable attribute information 81A to the programmable display 2B or the programmable display 2C instead of the programmable display 2A (or together with the programmable display 2A). It differs from the communication terminal 4 which concerns on.

  More specifically, the change information creation unit 132 of the communication terminal 4 transmits the variable attribute information 81A to the programmable display 2B and the programmable display 2C as shown in FIG. 8B. At this time, it is preferable to transfer only the value of the attribute whose change flag is “changed” in the variable attribute information, that is, the value that has been changed from the initial setting value. By transferring only the attribute values for the change in this way, it is possible to reduce the amount of communication and prevent rewriting of attributes that are not desired to be changed. When receiving the variable attribute information 81A, the programmable display 2B and the programmable display 2C overwrite the variable attribute information 81A on its own variable attribute information (81B or 81C).

  As described above, the variable attribute information 81 transmitted from a certain programmable display 2 to the communication terminal 4 can be transferred from the communication terminal 4 to another programmable display 2, thereby allowing the programmable display 2 and the communication terminal 4 to be transferred. By combining these, the attribute value of each part can be easily changed. Therefore, the user can change the display images of the plurality of programmable displays 2 more easily.

  In the description of FIG. 8, the example in which the variable attribute information 81A of the programmable display 2A is transmitted to the programmable display 2B and the programmable display 2C via the communication terminal 4 has been described. Change information obtained by changing the variable attribute information 81A received from 2A may be created and transmitted to the programmable display 2B and the programmable display 2C. In this case as well, only the attribute value whose change flag is “changed”, ie, the attribute value changed from the initial setting value is transferred to the programmable display 2B and the programmable display 2C. It is preferable. Furthermore, the communication terminal 4 may transmit the change information to the programmable display 2A.

[Embodiment 4]
In the image creation system according to the present invention, unlike the image creation system 200 of the first embodiment, the communication terminal 4 does not create the attribute information list by the attribute list creation unit 131 and is sent from the programmable display device 2. User interface screen data created in a format in which the value of can be changed may be displayed. Hereinafter, a fourth embodiment of the present invention will be described with reference to FIG. For convenience of explanation, members having the same functions as those described in the first embodiment are given the same reference numerals, and descriptions thereof are omitted.

  FIG. 9 is a block diagram illustrating configurations of the PC 1, the programmable display 2, and the communication terminal 4 in the image creation system 500. As illustrated, the image creation system 200 includes a personal computer (PC) 1, a programmable display 2D, a PLC 3, and a communication terminal 4A.

  The programmable display device 2D includes the receiving unit 50, the I / F 90, the display panel 61, the touch panel 60, and the storage unit 30, similar to the programmable display device 2 in the image creation system 200 of the first embodiment, and is programmable. A control unit 70 </ b> A is provided instead of the control unit 70 of the display device 2. The control unit 70A includes a variable attribute information creation unit 71A, a mode switching unit 72, and a display control unit 73.

  The variable attribute information creation unit 71A creates and changes the variable attribute information 81 as with the variable attribute information creation unit 71 in the first embodiment, but does not transmit the variable attribute information 81 to the communication terminal 4A. Based on the variable attribute information 81, the variable attribute information creation unit 71A creates user interface screen data that can be displayed on the Web browser 150 of the communication terminal 4A described later. Such user interface screen data is created in a format such as html, and processing for an input operation to a button or the like performed on the communication terminal 4A is defined by the program. The user interface screen displayed by the user interface screen data has a display in the same display form as the attribute information list created by the terminal control unit 130 of the communication terminal 4 in the image creation system 200. In addition, the variable attribute information creation unit 71A updates the variable attribute information 81 based on an attribute change value described later received from the communication terminal 4A.

  Similar to the communication terminal 4 in the image creation system 200, the communication terminal 4A includes a terminal communication unit 110, a terminal input unit 120, and a terminal display unit 140, and replaces the terminal control unit 130 of the communication terminal 4 with a Web browser 150. Is included.

  The terminal communication unit 110 receives user interface screen data from the programmable display device 2 and sends it to the Web browser 150. Further, the terminal communication unit 110 transmits the attribute value (attribute change value) changed by the Web browser 150 to the programmable display device 2 as change information.

  The web browser 150 displays the user interface screen data given via the terminal communication unit 110 on the terminal display unit 140, changes the attribute value according to the input operation accepted by the terminal input unit 120, The attribute change value obtained as a result is transmitted to the programmable display device 2 via the terminal communication unit 110.

  According to the above configuration, the terminal display unit 140 of the communication terminal 4A is displayed on the terminal display unit 140 by the Web browser 150 in the same display form as the attribute information list displayed on the communication terminal 4 of the first embodiment. The interface screen is displayed. Thereby, the user can change an attribute with the same operativity as the communication terminal 4 of Embodiment 1. FIG. Further, since the communication terminal 4A has the attribute change function by including the Web browser 150 included in a general communication terminal, the attribute list creation unit 131 and the change information creation unit 132 included in the communication terminal 4 are not necessary.

  The communication terminal 4A includes a web browser 150 that displays a user interface screen for changing attribute values based on user interface screen data. If the user interface screen can be displayed, a communication terminal other than the web browser 150 is used instead. May be included.

  The present embodiment can also be applied to the second embodiment described above.

[Modification]
(Modification 1)
The display data 31 according to the present invention may be given an individual identifier (ID or the like). The variable attribute information 81 (and change information) corresponding to the attribute information of the display data 31 is also given the same identifier as the display data 31 or information that can identify the identifier of the corresponding display data 31. It may be included.

  In this case, as described in the third embodiment, the terminal control unit 130 of the communication terminal 4 uses the variable attribute information 81 (variable attribute) received from a certain programmable display 2 (programmable display 2A in the example of FIG. 8). Information 81 </ b> A) or change information obtained by changing the variable attribute information 81 is transmitted to another programmable display device 2 (in FIG. 8, the programmable display device 2 </ b> B and the programmable display device 2 </ b> C) via the terminal communication unit 110. The display data 31 identifier (second identifier) stored in the programmable display device 2 is received from the programmable display device 2, and the display is given to or associated with the variable attribute information 81 or the change information. When the identifier (first identifier) of the data 31 matches the received identifier, the variable attribute information 81 or It may transmit the serial change information.

  Alternatively, the variable attribute information 81 or the change information received by the control unit 70 of the programmable display device 2 (the programmable display device 2B and the programmable display device 2C in FIG. 8) that receives the variable attribute information 81 or the change information. And the identifier of the display data 31 stored in the storage unit 80 of the own device may be collated, and the variable attribute information 81 or the change information may be received when they match.

  As a result, the variable attribute information 81 (or change information) can be transferred from the communication terminal 4 only to the programmable display device 2 including the display data 31 that matches the variable attribute information 81 (or change information), so that it differs by mistake. Transmission of the variable attribute information 81 (or change information) about the display data 31 can be prevented.

(Modification 2)
In the change mode, the programmable display device 2 in each of the above embodiments divides the size of the entire display image into rectangular regions (cells) of a predetermined size, and the position of each component included in the display data 31 is changed to the rectangle. You may memorize | store as information (For example, the 1st vertical cell, the 1st horizontal cell, etc.) which shows to which area | region components are arrange | positioned. Thus, the user can easily specify the position of the component without specifying the position coordinates in detail. Therefore, also when changing the position of a component using the programmable display 2 and the communication terminals 4 and 4A, the position of a component can be designated simply and the change of a display image becomes easier.

(Modification 3)
In each of the above embodiments, the example in which the storage unit 80 is divided into the first storage area and the second storage area has been described, but the first storage area and the second storage area may be separate storage devices. . That is, the storage unit 80 may be implemented by a first storage device that can only read data once stored and a second storage device that can freely read and write data.

(Modification 4)
A plurality of objects may be grouped in advance by the data creation unit 20 of the PC 1, and the attributes may be changed in units of groups. Since the parts can be grouped, the attribute can be changed efficiently by changing the attributes common to the grouped parts in a lump compared to changing the attributes in units of parts.

  In this case, the variable attribute information 81 of each grouped part includes information for specifying a group (for example, a group ID) and information for specifying an attribute to be collectively changed. When a group is selected by the user, the variable attribute information creation units 71 and 71A cause the storage unit 80 to store selected component specifying information 83 of components belonging to the selected group. Furthermore, the variable attribute information creation unit 71 reads out the variable attribute information 81 of the selected group from the storage unit 80 and transmits it to the communication terminal 4. The variable attribute information creation unit 71 A creates based on the variable attribute information 81. The transmitted user interface screen data is transmitted to the communication terminal 4A.

  The communication terminals 4 and 4A, based on the received information, in the state shown in FIG. 4B, instead of displaying the ID, attribute, and attribute value for the component, the ID for the group, the attribute for batch conversion, and Displays the value of the attribute. The user changes the attribute value in the manner shown in FIG. Thereby, it is possible to collectively change the attributes common to the objects belonging to the group.

[Example of software implementation]
The control block of the programmable display 2 (particularly the variable attribute information creation unit 71 and the mode switching unit 72 of the control unit 70), the data creation unit 20 of the PC 1, and the terminal control unit 130 of the communication terminal 4 are integrated circuits (IC chips). It may be realized by a logic circuit (hardware) formed in the same manner, or may be realized by software using a CPU (Central Processing Unit).

  In the latter case, the programmable display 2, the PC 1, and the communication terminal 4 are read by a computer (or CPU) that executes instructions of a program (control program) that is software that realizes each function, and the program and various data. A ROM (Read Only Memory) or a storage device (these are referred to as “recording media”), a RAM (Random Access Memory) in which the program is expanded, and the like are provided. And the objective of this invention is achieved when a computer (or CPU) reads the said program from the said recording medium and runs it. As the recording medium, a “non-temporary tangible medium” such as a tape, a disk, a card, a semiconductor memory, a programmable logic circuit, or the like can be used. The program may be supplied to the computer via an arbitrary transmission medium (such as a communication network or a broadcast wave) that can transmit the program. The present invention can also be realized in the form of a data signal embedded in a carrier wave in which the program is embodied by electronic transmission.
