Description

  The present invention relates to a programmable display that receives a status display of an external control device and an instruction input to the external control device.

  The conventional programmable display is configured to display only the selected screen on the display unit, and when transitioning to another screen, the contents are displayed from the nameplate of the screen changeover switch that is set. Operate to determine and select.

  In addition, the conventional programmable display is configured to read the information of the transition screen associated with the switch when there is a switch to another screen in the selected screen, and the obtained information A reduced display screen is generated from the image and operated so as to be displayed in an overlapping manner (see, for example, Patent Document 1).

  Furthermore, the conventional method for generating a reduced display screen of a screen that has been displayed in the past is configured to generate a reduced display screen by extracting a part from the screen displayed in the past. Only the display screen operates so as to be collectively displayed (for example, see Patent Document 2).

JP 2010-26627 A (paragraphs 0039 and 0040, FIGS. 3 and 4) WO 2007/116705 (0076 paragraph, FIG. 8)

  However, in the above conventional technique, only the selected screen is displayed on the display unit, so when changing to another screen, the screen changeover switch for changing to the desired screen is determined from the name plate. It takes time to make a decision. There is also a problem that a screen different from the operator's intention is selected by mistake.

  In addition, in the above conventional technique, only the switch switch information of the selected screen to another screen is read out. Therefore, if there is no setting for transition to the screen displayed in the past, the screen is temporarily displayed on the upper layer. There was a problem that the amount of operation work increased because it had to be re-selected again after the transition.

  Further, assuming that recovery from an incorrect selection is required, it is necessary to set an exclusive screen changeover switch for each screen, resulting in a problem that the setting work becomes complicated.

  The present invention has been made in view of the above, and can generate a reduced display screen of a past display screen from a past display history, and there is no setting for transition to a screen displayed in the past on a selected screen. Even in such a case, an object is to obtain a programmable display that can easily return to a previously displayed screen.

  In order to solve the above-described problems and achieve the object, the present invention relates to a display unit, a screen to be displayed on the display unit, and a plurality of pieces of data stored in association with transition destination information indicating a screen set as a transition destination on the screen. A programmable display for displaying the status of the external control device by displaying on the display means a screen selected from a plurality of screens stored in the data storage means The operation storage means for storing the history information, and based on the history information stored in the operation storage means, the screen selected in the past than the currently selected screen is read from the data storage means, and the data storage means Past screen generation means for generating a reduced screen of a screen selected in the past as the past reduced screen based on the read screen, Based on the transition destination information associated with the selected screen, the screen set as the transition destination for the currently selected screen is read from the data storage means, and based on the screen read from the data storage means, Transition destination screen generating means for generating a reduced screen of a screen set as a transition destination on the currently selected screen as a transition destination reduced screen, a past reduced screen, a currently selected screen, and a transition destination reduced screen Is displayed on the display means in a lump.

  According to the present invention, even when an unintended screen is selected by the screen selection operation, it is possible to easily return to the state before the operation by selecting a past screen displayed in a reduced size in the list display screen. Therefore, there is an effect that it is not necessary to set an exclusive screen changeover switch for each screen.

  Embodiments of a programmable display device according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

Embodiment 1 FIG.
FIG. 1 is a diagram showing an overall configuration of a programmable display according to a first embodiment of the present invention. The programmable display 100 includes an input unit 11, a display unit 12, an external control device connection interface (I / F) 13, an input processing unit 20, a display generation unit 21, an operation storage unit 22, a data storage unit 23, and transition / update. An information determination unit 24 is provided.

  The input unit 11 is an input interface that receives an operation by an operator. The display unit 12 is a functional unit that displays information, and a liquid crystal panel, an organic EL panel, or the like is applicable. Note that the input unit 11 and the display unit 12 may constitute a touch panel. The external control device connection I / F 13 is an interface for connecting the external control device 102, and is a USB connector, an RS-232C connector, or the like. The input processing unit 20 selects the current screen data number according to the operation of the input unit 11 by the operator or the instruction received from the external control device 102 via the external control device connection I / F 13, and selects the screen data number. Generate information. The operation storage unit 22 holds screen data number selection information sent from the input processing unit 20 to the display generation unit 21. The display generation unit 21 extracts data from the data storage unit 23 based on the selected screen data number and generates a screen corresponding to the screen data number. When the screen data number selected in the past is stored in the operation storage unit 22, the display generation unit 21 generates a reduced display screen corresponding to the stored data. Further, the display generation unit 21 generates a reduced display screen corresponding to the transition information included in the current screen. The transition / update information determination unit 24 determines whether the selected current screen includes transition information to the next screen. If the transition information is included, the transition / update information determination unit 24 sets the transition screen data number to the transition information. Extract as

  The data storage unit 23 stores data (component data) of each of a plurality of types of components arranged on the screen, and screen data (screen data) including one or more components. The screen data includes information indicating the properties of the screen in addition to information indicating the layout of the parts. By setting the transition information in the screen properties, it is possible to transition the screen regardless of the operation at the input unit 11 or the instruction from the external control device 102. For example, an operation of automatically transitioning to a menu screen after displaying the title screen for a certain period of time is possible. It is also possible to set the priority as a property for each screen.

  Next, the operation of the programmable display device 100 will be described. FIG. 2 is a flowchart illustrating an example of an operation procedure in the programmable display device 100.

  The input processing unit 20 selects the data number of the current screen in response to an operator's input operation at the input unit 11 or an instruction received from the external control device 102 via the external control device connection I / F 13 (step S101). . When the input operation or the received instruction requests display in a batch display format (step S102 / Yes), the transition / update information determination unit 24 determines whether there is transition information for the next screen on the current screen. Is determined (step S103). Here, the transition / update information determination unit 24 determines that there is transition information to the next screen when there is a screen switch in the current screen. When the transition information to the next screen is on the current screen (step S103 / Yes), the display generation unit 21 generates a reduced display screen (transition destination reduced screen) of the screen data number corresponding to the transition information (step S104). ). The display generation unit 21 generates a reduced display screen of the screen data number held in the operation storage unit 22 (step S105). The display generation unit 21 collectively displays the reduced display screen of the next screen, the current screen, and the reduced display screen of the past screen in time series on the display unit 12 (step S106). FIG. 3 is a view showing one display of the next screen, the current screen, and the past screen in the programmable display 100. The collective display screen shown in FIG. 3 is configured to collectively display a screen 200 selected in the past, a currently selected screen 201, and the next selectable screens 200 and 202 to 205 in a time series. Has been. A screen changeover switch 300 is set on the currently selected screen 201, and screen transition is instructed by pressing the corresponding switch.

  On the other hand, when the current screen does not include transition information to the next screen (step S103 / No), the display generation unit 21 generates a reduced display screen of the screen data number held in the operation storage unit 22. (Step S109). The display generation unit 21 collectively displays a reduced display screen of the current screen and the past screen on the display unit 12 (step S110).

  If the input operation or the received instruction does not request display in the batch display format (step S102 / No), the display generation unit 21 displays the current screen on the display unit 12 (step S111).

  After performing the batch display of the reduced display screen of the next screen, the current screen, the reduced display screen of the past screen, or the batch display of the current screen, the reduced display screen of the past screen, or the display of the current screen, the operation storage unit 22 The data number of the current screen selected in step S101 is held (step S107). After displaying the screen, the screen continues to be displayed until a screen transition instruction is received. If there is a screen transition instruction (Yes in step S108), the process returns to step S101.

  In the above description, the transition / update information determination unit 24 determines that the transition information to the next screen is included in the current screen when the screen changeover switch exists in the current screen. It is also possible to make a determination based on the setting in the menu 23 (setting in the screen properties).

  The determination as to whether or not to display in a batch display format including the past screen and the next screen may be made based on settings (screen properties) in the data storage unit 23. That is, whether to display together with previously selected screens or screens that can be selected next or whether to display them alone is set as a property for each screen, and the display generation unit 21 switches the display format according to the setting. Also good.

  In addition, if there are many past screens and next screens that are displayed together with the current screen, the screen may be scrolled so that only a certain number appears on the screen, and the priority set in advance as a screen property You may extract and display a high thing. Alternatively, the reduction ratio may be changed according to the number of screens. Whether or not these functions are performed may be switched according to an input from the external control device 102 or a setting in the data storage unit 23.

  According to this embodiment, since it is possible to display from the previously selected screen to the next selectable screen in a lump, even when an unintended screen is selected by the screen selection operation, By selecting a past screen reduced in the list display screen, it is possible to easily return to the state before the operation. In other words, the reduced display screens displayed in the past on the screen of the programmable display are collectively displayed in time series, and the reduced display screen can be selected and transitioned to that screen. Even if you accidentally switch to a different screen, you can easily recover to the stage before selection.

  Furthermore, it is not necessary to set the screen change switch so that the screen changes to the screen before the selection, assuming the wrong selection, so it is complicated to set the screen change switch while checking the hierarchy in creating screen data at the time of design Work can be greatly reduced. Specifically, when there are screens (1) to (5) in addition to the menu screen, the screen (1) corresponds to the menu screen and (2) to (5). It is necessary to install a screen changeover switch. On the other hand, on the screen of (4), it is necessary to install a menu screen and screen changeover switches corresponding to (1) to (3) and (5). As described above, since the screen change switch is different for each screen, it is troublesome to set the screen change switch without error on all the screens. In this embodiment, such a complicated work is unnecessary.

Embodiment 2. FIG.
The configuration and overall operation flow of the programmable display according to the second embodiment of the present invention are the same as those of the first embodiment. However, in the present embodiment, when generating a reduced display screen of the screen number held in the operation storage unit 22, if information to be updated is included in the past screen, it is updated to the current value. . That is, the target screen is analyzed by the transition / update information determination unit 24 and update information is acquired from the input processing unit 20 as necessary.

  FIG. 4 is a diagram showing a flow of operations when generating a reduced display screen of a screen previously displayed by the programmable display according to the second embodiment. This operation is equivalent to step S105 or step S109 in FIG. 2, and the overall operation flow other than this part is as described in the first embodiment with reference to FIG.

  When generation of a reduced display screen of a screen selected in the past is started, the display generation unit 21 reads a screen data number stored in the operation storage unit 22 (step S201). Further, the display generation unit 21 reads the screen data of the corresponding number from the data storage unit 23 (step S202). The transition / update information determination unit 24 determines whether information to be updated is included in the screen data (step S203). For example, a variable to which a value acquired from the external control device 102 is substituted is regarded as information to be updated. When the information to be updated is included in the screen data (step S203 / Yes), the input processing unit 20 acquires the current value of the external control device 102 via the external control device connection I / F 13 (step S204). The input processing unit 20 passes the current value acquired from the external control device 102 to the display generation unit 21. The display generation unit 21 updates the screen data using the current value of the external control device 102 (step S205). Further, the display generation unit 21 generates a reduced display screen of the updated screen (step S206).

  If the information to be updated is not included in the screen data (step S203 / No), the display generation unit 21 generates a reduced display screen based on the screen data read from the data storage unit 23 (step S203 / No). S207).

  In the present embodiment, when the previously selected screens are collectively displayed, the information in the screen can be updated to the current value and displayed. That is, even if a reduced display screen is generated from a previously selected screen, the information displayed in the reduced display screen is the same value as the current set value. Therefore, when the operator views the generated reduced display screen, it is possible to suppress an erroneous determination based on past old information. In other words, when generating a reduced display screen of a screen that has been selected in the past, updatable information such as numerical values included in the screen data can be updated to the current value, so the screens that are displayed in a batch It is possible to prevent old and new information from being mixed, and to suppress recognition errors based on old information.

  The programmable display according to the present invention is suitable for use as a display terminal of a large-scale system that requires display with a large amount of information, or when a high-resolution monitor device is applied to the display unit.
