Abstract

<P>PROBLEM TO BE SOLVED: To improve operator's operability of an apparatus provided with a graphic operation panel. <P>SOLUTION: In a display apparatus for control, a touch panel 25 detects operator's depression on a component image on a display picture. When operator's continuous depression onto the component image for prescribed time is detected by the touch panel 25, an event execution part 27 executes prescribed processing allocated to the component image. An image state changing part 26 changes the display state of the component image during the period that the touch panel 25 detects operator's continuous depression on the component image before starting the execution of the prescribed processing by the event execution part 27. Consequently, the operator can recognize the necessity of continuous depression on the component image and is not bewildered to perform succeeding operation. Thereby the operability of the display apparatus 20 for control is improved. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a control display device excellent in operability, a drawing editor device that generates screen data used by the control display device, a display control program that implements the control display device in software, and the display control The present invention relates to a computer-readable recording medium storing a program.

  Conventionally, a graphic operation panel including a programmable display has been widely used as an HMI (Human Machine Interface) of a control system.

  The graphic operation panel displays the state of the device on the operation screen as a component image representing the device, notifies the operator, and accepts an operation on the operation screen (pressing the component image) by the operator. Accordingly, the display state of the component image is changed and the device represented by the component image is controlled.

  Here, in the conventional graphic operation panel, processes assigned to devices (switches, etc.) represented by the component image are executed at various timings based on the pressing process of the component image by the operator.

  For example, a technique (ON delay) is known in which an operator keeps pressing a part image for a certain time and then turns on the device to execute some processing. In addition, a technique (OFF delay) is known in which a switch is turned off after a predetermined time has elapsed since the operator finished pressing the component image.

  In Patent Document 1, in conjunction with a single switch operation, a plurality of types of signals having different output timings can be output, and the output timings of the signals are detected using processing instructions. A programmable display device that performs a predetermined processing operation specified by the processing instruction word is disclosed.

  According to Patent Document 1, various control operations performed in conjunction with the switch operation can be easily set.

Further, Patent Document 2 discloses a delay switch that maintains an on state for a certain time after an off operation, although it is different from a graphic operation panel.
Japanese Laid-Open Patent Publication No. 11-065768 (Publication Date: March 09, 1999) Japanese Laid-Open Patent Publication No. 05-274962 (Publication Date: March 26, 1992)

  However, the above-described conventional technique has a problem that the operability of the apparatus by the operator is poor.

  For example, when the ON delay is set and the operator keeps pressing the part image, the display state of the part image remains unchanged. Therefore, the operator can determine whether the switch is turned on if the part image is continuously pressed while the part image is being pressed, or whether the switch is already turned on based on the display state of the part image. Cannot be determined. From this, the operator cannot immediately determine what operation should be performed next. Such a problem also occurs during the OFF delay.

  Further, in the apparatus of Patent Document 1, since the display state of the switch is not changed while different processing operations are being performed, the operator indicates what processing is currently being performed, Can not know from. Therefore, the operator cannot immediately determine what operation should be performed next.

  Further, in the delay switch of Patent Document 2, the display state of the switch remains on after the off operation. In this state, the user cannot distinguish between the on state after the switch is turned off and the normal on state. Also in this case, the operator cannot immediately determine what operation should be performed next.

  SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a display device for control excellent in operability, a drawing editor device for generating screen data used by the display device for control, and a display for control.

  In order to solve the above-described problem, the control display device according to the present invention is configured to detect, on a display screen, an area input unit that detects pressing of a component image by an operator and a continuous pressing of the component image by the operator. In the control display device comprising a processing execution means for executing a predetermined process assigned to the component image when the predetermined time is detected by the region input means. It further comprises display state changing means for changing the display state of the component image while the continuous input of the component image by the operator is detected by the area input means before the execution of processing is started. It is characterized by having.

According to the above configuration, in this apparatus, the continuous input of the component image by the operator is detected by the area input unit for a predetermined time before the execution of the predetermined process by the process execution unit is started. The display state of the component image is changed by the display state changing means. That is, the display state of the component image is changed from when the operator presses the component image until the predetermined processing assigned to the component image is executed by the processing execution unit. Based on the change of the display state of the component image, the operator now understands that the component image needs to be kept pressed for a predetermined time in order to turn on the component image.

[Control unit 21]
The control unit 21 comprehensively controls each member provided in the control display device 20. For example, the screen data received by the drawing editor side communication unit 22 is received and stored in the screen data storage unit 23.

[Graphic editor side communication unit 22]
The drawing editor side communication unit 22 receives the screen data transmitted from the drawing editor device 10 and outputs the screen data to the control unit 21.

[Screen Data Storage Unit 23]
The screen data storage unit 23 stores screen data received by the control display device 20 through the drawing editor side communication unit 22.

[Display 24]
The display 24 displays a display screen. When the operator touches the component image displayed on the display 24, the control display device 20 executes a predetermined process associated with each component. Details of this will be described later.

[Touch panel 25]
The touch panel 25 receives input by an operator to any one of the component images on a display screen constituted by a plurality of component images, and outputs coordinate data for identifying the received component image. That is, the touch panel 25 detects a touch operation by an operator on any component image included in the display screen displayed on the display 24. Thereafter, the touch panel 25 outputs coordinate data specifying the component image touched by the operator.

[Event execution unit 27]
The event execution unit 27 displays a display screen composed of various component images on the display 24 based on the screen data stored in the screen data storage unit 23. Further, the event execution unit 27 executes a predetermined process assigned to the component image touched by the operator based on the coordinate data and the screen data.

[Interlock section 28]
When a predetermined condition is satisfied, for example, when a bit in the component image is ON, the interlock unit 28 sets the touch of the component image by the operator so that it is not detected by the touch panel 25. In addition, the interlock unit 28 sets the event execution unit 27 so that the predetermined process is not executed even when the touch of the component image by the operator is detected by the touch panel 25. By making such a setting, the interlock unit 28 realizes locking (interlock) with respect to the component image.

[PLC side communication unit 29]
The PLC-side communication unit 29 communicates with the PLC 40 through a communication line, and transmits the control content for the device 50 based on the predetermined processing content executed by the event execution unit 27 to the PLC 40. Further, data indicating the state of the device 50 is received from the PLC 40.

[Screen data]
The screen data generated in the drawing processing unit 12 and transmitted to the control display device 20 is a tag indicating the correspondence between the area (component image) on the screen and the device 50 corresponding to display and input in each area. Are combined. By using this screen data, the control display device 20 can switch and display a plurality of unit screens. In addition, the tag includes a file number indicating a unit screen in which the tag is valid, an event name that specifies processing content to be executed on the unit screen, and reference information that is referenced for each event.

[ON delay]
In the control display device 20, an ON delay can be set in response to a touch of a component image by an operator. This ON delay means that the touch of the part image by the operator is continuously detected by the touch panel 25 for a predetermined time. In the control display device 20, a predetermined process assigned to the component image is executed by the event execution unit 27 after the ON delay has elapsed. That is, at this time, a switch (device 50 or the like) represented by the component image is turned on. This example will be described with reference to FIG.

  FIG. 2 is a diagram illustrating a change in the display state of the component image when the touch operation of the component image by the operator is continuously detected by the touch panel 25 during the delay time ton.

  As shown in this figure, in the control display device 20, when the touch of the component image by the operator is OFF, the OFF image is displayed on the display 24 as the component image. In other words, in the control display device 20, when the touch of the component image by the operator is not detected by the touch panel 25, the event execution unit 27 displays an OFF image as the component image on the display 24.

  Here, when the touch of the component image by the operator changes from OFF to ON, the display state of the component image changes from the OFF image to the ON delay image. In other words, in the control display device 20, when the touch panel 25 detects that the touch of the component image by the operator is started, the image state changing unit 26 changes the display state of the component image from the OFF image to the ON delay image. Change to At this time, in the control display device 20, the switch has not yet changed from OFF to ON. That is, even if the operator touches the component image, the switch remains OFF, and the event execution unit 27 does not execute a predetermined process assigned to the component image.

  The ON delay image is an image for informing the operator that the switch is turned on when the part image is continuously touched for a predetermined time. Based on the display of this image, the operator continues to touch the component image. In the example illustrated in FIG. 2, when the operator continues to touch the component image for the delay time ton, the switch is turned on, and the display state of the component image changes from the ON delay image to the ON image.

  That is, while the touch of the component image by the operator is continuously detected by the touch panel 25 during the delay time ton, the ON delay image is continuously displayed as the component image. When the touch panel 25 detects that the delay time ton has elapsed and the operator has finished touching the component image, the image state changing unit 26 changes the display state of the component image from the ON delay image to the ON image.

  Thereby, in the control display device 20, the switch is turned on after the touch of the component image by the operator is continuously turned on for the delay time ton. At this time, a predetermined process assigned to the component image touched by the operator is executed by the event execution unit 27.

  By adopting such a configuration, the control display device 20 executes the predetermined process assigned to the component image only after the operator continues to touch the component image for a predetermined time. That is, the control display device 20 can prevent malfunction when an operator touches a component image by mistake.

  Further, in the control display device 20, the image state changing unit 26 displays the component image in the ON delay image during the delay time ton. Therefore, based on the fact that the display state of the component image is an ON delay image after the operator touches the component image, the switch will not be turned on unless the component image is continuously touched. to understand.

  That is, in the control display device 20, the image state changing unit 26 changes the display state of the component image during the ON delay, so that the fact that the ON delay is being performed can be notified to the operator. Since the operator can know the current state of the control display device 20 after touching the component image according to the display state of the component image, the operation is not confused. In other words, the control display device 20 is more user-friendly than the conventional device.

  In this way, the control display device 20 more actively presents an image showing the current state of the device to the operator as compared to the conventional device that does not change the display state of the component image during the ON delay. That is, the control display device 20 exhibits more excellent operability than the conventional device.

[Processing when setting ON delay]
In the control display device 20, as shown in FIGS. 3 to 6, the bit state and buzzer sound are appropriately turned ON or OFF in accordance with the detection timing of the touch state of the component image by the touch panel 25. Or This operation is appropriately performed by the event execution unit 27.

  FIG. 3 shows an example of a change in the display state of the component image, a change in the bit state, and a change in the buzzer sound when the touch operation of the component image by the operator is continuously detected by the touch panel 25 during the delay time ton. FIG.

  In the example shown in FIG. 3, after the touch of the component image by the operator is continuously detected by the touch panel 25, the event execution unit 27 sets the bit to ON and turns on the buzzer. As a result, the bit assigned to the component image touched by the operator is set to ON, and a buzzer indicating that the switch is ON is sounded to the operator.

  In the example of FIG. 3, after the touch of the component image by the operator is no longer detected by the touch panel 25, the image state changing unit 26 changes the display state of the component image from the ON delay image to the OFF delay image. On the other hand, the event execution unit 27 continues to set the bit to the ON state. Such an operation can be applied to a set switch or a word switch.

  FIG. 4 shows the change in the display state of the component image, the change in the bit state, and the change in the buzzer sound when the touch operation of the component image by the operator is continuously detected by the touch panel 25 during the delay time ton. It is a figure which shows the example of.

  In the example illustrated in FIG. 4, after the touch of the component image by the operator is no longer detected by the touch panel 25, the event execution unit 27 sets the bit to OFF. Such an operation can be applied to a momentary switch.

  FIG. 5 shows further changes in the display state of the component image, the change in the bit state, and the change in the buzzer sound when the touch operation of the component image by the operator is continuously detected by the touch panel 25 during the delay time ton. It is a figure which shows another example.

  As shown in FIG. 5, the control display device 20 may continue to sound the buzzer while the switch is ON. That is, in the control display device 20, after the touch of the component image by the operator is continuously detected by the touch panel 25 during the delay time ton, the touch panel 25 detects the end of the touch of the component image by the operator. Until this time, the event execution unit 27 may continue to turn on the buzzer. In other words, the touch of the part image by the operator is continuously detected by the touch panel 25 during the delay time ton. As a result, the execution of the predetermined process by the event execution unit 27 starts and the part image by the operator is started. Until the touch is no longer detected by the touch panel 25, the event execution unit 27 may keep the buzzer ON.

  FIG. 6 shows further changes in the display state of the component image, the change in the bit state, and the change in the buzzer sound when the touch operation of the component image by the operator is continuously detected by the touch panel 25 during the delay time ton. It is a figure which shows another example.

  In the example shown in FIG. 6, after the touch of the part image by the operator is continuously detected by the touch panel 25 during the delay time ton, the event execution unit 27 sets the bit from ON to OFF. Such an operation can be applied to a reset switch.

[OFF delay]
In the control display device 20, an OFF delay can be set in response to a touch of a component image by an operator. The OFF delay is a period from when the touch of the part image by the operator is detected by the touch panel 25 to when the event execution unit 27 starts executing a predetermined process. After the OFF delay has elapsed, execution of a predetermined process by the event execution unit 27 is started. That is, at this time, the switch (device 50 or the like) represented by the component image is turned off. Further, in this OFF delay, in the control display device 20, the image state change unit 26 changes the display state of the component image. This example will be described with reference to FIG.

  FIG. 7 shows a component image when the touch operation of the component image by the operator is not continuously detected by the touch panel 25 during the delay time toff after the end of the touch operation of the component image by the operator is detected by the touch panel 25. It is a figure which shows the change of a display state.

  As shown in this figure, in the control display device 20, when the touch of the component image by the operator is ON, the ON image is displayed on the display 24 as the component image. In other words, in the control display device 20, when the touch of the component image by the operator is detected by the touch panel 25, the event execution unit 27 displays the ON image as the component image on the display 24.

  Here, in the control display device 20, when the touch of the component image by the operator is finished, an OFF delay is set. That is, in the control display device 20, when the touch of the component image by the operator is detected by the touch panel 25, the image state changing unit 26 changes the display state of the component image from the ON image to the OFF delay image. At this time, in the control display device 20, the switch has not yet changed from ON to OFF. That is, even when the operator finishes touching the component image, the switch remains ON, and the event execution unit 27 executes a predetermined process assigned to the component image.

  This OFF delay image is an image for informing the operator that the switch is turned OFF when a predetermined time has elapsed after the end of touching the component image. In FIG. 7, the display state of the component image is an OFF delay image while the delay time toff elapses after the operator touches the component image. In other words, after the end of touching the component image by the operator is detected by the touch panel 25, the display state of the component image is changed to the OFF delay image by the image state changing unit 26 while the delay time toff elapses. .

  As a result, in the control display device 20, the switch is turned off after the touch panel 25 detects the end of the touch of the component image by the operator. At this time, the predetermined process assigned to the component image touched by the operator is completed.

  By adopting such a configuration, in the control display device 20, the execution of the predetermined process to which the component image is assigned is completed only after a predetermined time has elapsed since the operator finished touching the component image. To do. Accordingly, the operator can operate the control display device 20 with a certain clearance.

  In the control display device 20, the display state of the component image is an OFF delay image during the delay time toff. Therefore, the operator understands that the switch is not turned off until a predetermined time has passed since the display of the component image is an OFF delay image after the touch of the component image is finished.

  That is, in the control display device 20, the image state changing unit 26 changes the display state of the component image during the OFF delay, so that the fact that the OFF delay is being performed can be notified to the operator. In other words, the operator can know what state the control display device 20 is currently in after the touch of the component image is finished according to the display state of the component image. There is no. In other words, the control display device 20 is also more user-friendly than the conventional device in this respect.

  In this way, the control display device 20 more actively presents an image showing the current state of the device to the operator as compared to the conventional device that does not change the display state of the component image during the OFF delay. That is, the control display device 20 exhibits more excellent operability than the conventional device.

[Process when OFF delay is set]
In the control display device 20, as shown in FIGS. 8 to 10, even when the OFF delay is set, the state of the bit, Turn the buzzer on or off as appropriate. This operation is appropriately performed by the event execution unit 27.

  FIG. 8 shows a component image when the touch operation of the component image by the operator is not continuously detected by the touch panel 25 during the delay time toff after the end of the touch operation of the component image by the operator is detected by the touch panel 25. It is a figure which shows an example of the change of a display state, the change of a bit state, and the change of a buzzer sound.

  In the example illustrated in FIG. 8, when the touch of the component image by the operator is detected by the touch panel 25, the event execution unit 27 sets the bit to ON and sets the buzzer to ON. As a result, the bit assigned to the component image touched by the operator is set to ON, and a buzzer indicating that the switch is ON is sounded to the operator.

  In the example of FIG. 8, the image state changing unit 26 changes the display state of the component image from the OFF delay image after the delay time toff has elapsed since the end of the touch of the component image by the operator is detected by the touch panel 25. Change to OFF image. On the other hand, the event execution unit 27 continues to set the bit to the ON state. Such an operation can be applied to a set switch or a word switch.

  FIG. 9 shows a component image when the touch operation of the component image by the operator is not continuously detected by the touch panel 25 during the delay time toff after the end of the touch operation of the component image by the operator is detected by the touch panel 25. It is a figure which shows the other example of a change of a display state, a change of a bit state, and a change of a buzzer sound.

  In the example shown in FIG. 9, when the touch of the part image by the operator is detected by the touch panel 25, the event execution unit 27 sets the bit to ON and turns on the buzzer. Further, while the touch of the part image by the operator is continuously detected by the touch panel 25, the event execution unit 27 continues to set the bit to ON and keep the buzzer ON. Further, the event execution unit 27 continues to set the bit ON and the buzzer ON until the delay time toff elapses after the touch of the part image by the operator is detected by the touch panel 25. Such an operation can be applied to a momentary switch.

  FIG. 10 shows a component image when the touch operation of the component image by the operator is not continuously detected by the touch panel 25 during the delay time toff after the end of the touch operation of the component image by the operator is detected by the touch panel 25. FIG. 10 is a diagram illustrating still another example of a change in display state, a change in bit state, and a change in buzzer sound.

  In the example illustrated in FIG. 10, after the delay time toff has elapsed after the end of touching the component image by the operator, the event execution unit 27 sets the bit from ON to OFF. Such an operation can be applied to a reset switch.

[Waiting to push twice]
In the control display device 20, it is possible to set a tapping acceptance time t <b> 2 for a touch of a component image. The twice-pressing acceptance time t2 is a time for waiting for the second touch of the component image by the operator after the touch of the first touch of the component image by the operator is detected by the touch panel 25. During the twice-pressing acceptance time t2, in the control display device 20, the image state changing unit 26 changes the display state of the component image. Therefore, this example will be described with reference to FIG.

  FIG. 11 shows a case in which the touch panel 25 detects the second touch operation of the component image after the elapse of the second press acceptance time t <b> 2 after the first touch operation of the component image is detected by the touch panel 25. It is a figure which shows the change of the display state of a component image.

  As shown in this figure, in the control display device 20, when the touch of the component image by the operator is OFF, the OFF image is displayed on the display 24 as the component image. In other words, in the control display device 20, when the first touch of the component image by the operator is not detected by the touch panel 25, the event execution unit 27 displays the OFF image as the component image on the display 24.

  Here, in the control display device 20, when the first touch of the component image by the operator is completed, a double press acceptance time t2 is set. That is, in the control display device 20, when the first touch of the component image by the operator is detected by the touch panel 25, the image state changing unit 26 changes the display state of the component image from the OFF image to the waiting image twice. And change. Thereafter, the display state of the component image remains the image waiting for the second press during the second press acceptance time t2.

  At this time, in the control display device 20, the switch has not yet changed from OFF to ON. That is, even when the operator finishes the first touch of the component image, the switch remains OFF, and the event execution unit 27 does not execute the predetermined process assigned to the component image.

  In the control display device 20, after the first touch of the part image by the operator is detected by the touch panel 25, the twice-push waiting image continues to be displayed as the part image while the second press acceptance time t2 elapses. Here, when the touch panel 25 detects the second touch of the component image by the operator before the time t2 for accepting the second press elapses, the switch is turned on. At this time, the image state changing unit 26 changes the display state of the component image twice from the waiting image to the ON image. In addition, the event execution unit 27 executes a predetermined process assigned to the component image.

  By adopting such a configuration, in the control display device 20 in which the twice push acceptance time t2 is set, the second push acceptance time after the first touch of the component image by the operator is detected by the touch panel 25. Until t2 elapses, the predetermined process assigned to the component image is executed only after the touch panel 25 detects the second touch of the component image by the operator. As a result, the control display device 20 can prevent malfunction when the operator touches the component image by mistake.

  Further, in the control display device 20, the display state of the component image is a twice-push waiting image during the twice-push acceptance time t2. This double-push waiting image is an image for informing the operator that it is necessary to touch the component image again after a predetermined time elapses after the first touch of the component image. Therefore, the operator touches the component image again after the predetermined time elapses after the first touch of the component image is finished, based on the fact that the display state of the component image is an image waiting for pressing twice. Otherwise, understand that the switch will not turn off.

  In other words, in the control display device 20, the double press acceptance time t <b> 2 is now set for the operator by the image state changing unit 26 changing the display state of the component image during the double push acceptance time t <b> 2. You can be notified of the facts that are being made. Based on the display state of the component image, the operator can know the current state of the control display device 20 after finishing the first touch of the component image. It wo n’t be crazy. In other words, the control display device 20 is also more user-friendly than the conventional device in this respect.

  As described above, the control display device 20 more positively displays an image indicating the current status of the device to the operator than the conventional device that does not change the display state of the component image when waiting for a second press. Present. That is, the control display device 20 exhibits more excellent operability than the conventional device.

[Processing when waiting to be pressed twice]
Note that, in the control display device 20, as shown in FIGS. 12 to 14, even when the double press acceptance time t 2 is set, the bit is adjusted in accordance with the detection timing of the touch state of the component image by the touch panel 25. The buzzer sound and the buzzer sound are turned ON or OFF as appropriate. This operation is appropriately performed by the event execution unit 27.

  FIG. 12 shows the case where the touch panel 25 detects the second touch operation of the part image by the operator after the tapping acceptance time t <b> 2 elapses after the first touch operation of the part image by the operator is detected by the touch panel 25. It is a figure which shows an example of the change of the display state of a component image, the change of a bit state, and the change of a buzzer sound.

  In the example shown in FIG. 12, when the first touch of the component image by the operator is detected by the touch panel 25, the event execution unit 27 turns on the buzzer. When the second touch of the component image by the operator is detected by the touch panel 25, the event execution unit 27 sets the bit to ON and turns the buzzer ON again. As a result, the bit assigned to the component image touched twice by the operator is set to ON, and a buzzer indicating that the switch is ON is sounded to the operator.

  In the example of FIG. 12, when the first touch of the component image by the operator is detected by the touch panel 25, the image state changing unit 26 changes the display state of the component image from the OFF image to the waiting image twice. . When the second touch of the component image by the operator is detected by the touch panel 25, the image state changing unit 26 changes the display state of the component image twice to change from the waiting image to the ON image. On the other hand, the event execution unit 27 keeps setting the bit to ON when the touch panel 25 detects the second touch of the component image by the operator. Such an operation can be applied to a set switch, a word switch, and a momentary switch.

  FIG. 13 shows the case where the touch panel 25 detects the second touch operation of the part image by the operator after the tapping acceptance time t <b> 2 elapses after the first touch operation of the part image by the operator is detected by the touch panel 25. It is a figure which shows the other example of the change of the display state of a component image, the change of a bit state, and the change of a buzzer sound.

  In the example illustrated in FIG. 13, when the second touch of the component image by the operator is detected by the touch panel 25, the event execution unit 27 sets the bit to OFF and turns on the buzzer. Such an operation can be applied to a reset switch.

  In the control display device 20, when the twice-pressing acceptance time t2 is set, after the first touch of the component image by the operator is detected by the touch panel 25, the set twice-pressing acceptance time t2 is set. If the second touch of the component image by the operator is not detected by the touch panel 25 even after elapses, the image state changing unit 26 changes the display state of the component image to the original state, or further You may change to a state. This example will be described with reference to FIG.

  FIG. 14 shows that the touch operation of the second touch of the component image by the operator was not detected by the touch panel 25 after the tapping acceptance time t2 has elapsed since the first touch motion of the component image by the operator was detected by the touch panel 25. It is a figure which shows an example of the display state of a component image in a case, the change of a bit state, and the change of a buzzer sound.

  In the example shown in this figure, after the first touch of the component image by the operator is detected by the touch panel 25, the second touch of the component image by the operator even if the set second press acceptance time t2 has elapsed. Is not detected by the touch panel 25, the image state changing unit 26 changes the display state of the component image twice to change from the waiting image to the original OFF image. That is, in the control display device 20, when the operator does not touch the part image for the second time during the second press acceptance time t2, the event execution unit 27 executes a predetermined process assigned to the part image. do not do. Therefore, the switch is not turned on and remains off.

  By such an operation, the control display device 20 can notify the operator that the time for which the double pressing is valid has ended by a change in the display state of the component image. As a result, the operator can take a response according to the situation on the spot, such as performing the touch operation on the component image again. In this case, the control display device 20 can further improve the operability of the device by the operator.

〔interlock〕
In the control display device 20, an interlock can be set for the component image displayed on the display 24. The interlock here means that even if the operator touches the component image, even if the touch panel 25 does not accept the touch operation or the touch panel 25 accepts the touch operation, the event execution unit 27 causes the component image to be This is a setting that does not execute a predetermined process assigned to. In the control display device 20, the interlock unit 28 sets such an interlock.

  In the control display device 20, when the interlock is set in the component image by the interlock unit 28, the image state changing unit 26 changes the display state of the component image. For example, the image state changing unit 26 changes the display state of the component image from an ON image or an OFF image to an image different from the ON image and the OFF image indicating that the interlock is currently set for the component image. To do.

  Thus, the operator understands that the interlock is currently set for the component image. Therefore, the operator does not have to make an unnecessary touch on such a component image. In this way, the control display device 20 more actively presents an image showing the current state of the device to the operator, compared to a conventional device that does not change the display state of the component image when the interlock is set. . That is, the control display device 20 exhibits more excellent operability than the conventional device.

  Note that the image state changing unit 26 of the control display device 20 may change the display state of the component image to any other state different from the original ON image or OFF image. The change of state here includes changing the image itself to another different image, blinking the image, and the like. For example, when changing the display state of the ON image or the OFF image, the image state changing unit 26 may change the ON image or the OFF image into a gray scale processed image or an embossed processed image.
