The recording medium.
[0002]
[Prior art]
A programmable controller is used to control controlled devices sequentially. Input devices such as switches and sensors and output devices such as electromagnetic switches, relays, solenoids, motors, and cylinders are connected to the programmable controller. This programmable controller controls a controlled device according to a control program created in advance.
[0003]
Various devices are allocated to the memory in the programmable controller. Here, the device refers to elements such as a relay (input relay, output relay, input / output relay, auxiliary relay, etc.), timer, counter, data memory, etc. used in the control program. There are two types of devices: bit devices (relays, counters, timer contacts, etc.) consisting of 1-bit areas on the memory, and word devices (timer and counter set values, timers, Counter current value, data memory, etc.). These devices are specified by device information including a device type and a device number. That is, the address on the memory to which the device is allocated is specified using the device type and device number. The device type represents the name of the device, and the device number is a number assigned to identify a plurality of devices of the same device type.
[0004]
The state of the device changes with the control operation of the controlled device by the programmable controller. For example, on / off of a bit device such as an input relay or a data value of a word device such as a data memory changes.
[0005]
A display device is used to display the device status of the programmable controller. This display device is used not only to display the device status, but also to set the device status of the programmable controller.
[0006]
Various display screens can be displayed on the display of the display device. The display screen of the display device is created in advance as screen data by the screen data creation device. The screen data created by the screen data creation device is transferred to and stored in a memory in the display device. A display screen is displayed on the display of the display device based on the screen data stored in the memory.
[0007]
In the screen data creation device, various display screens can be created by arranging various parts on the editing screen. Here, the component refers to a component of the display screen that constitutes the display screen.
[0008]
Arbitrary devices of the programmable controller can be assigned to the components of the display screen. Thereby, the device state of the programmable controller can be displayed by the components of the display screen. For example, when a lamp part is arranged as a part and the lamp part is assigned to the 100th input relay of the programmable controller, the on / off state of the 100th input relay can be displayed by the lamp part.
[0009]
Moreover, the display of the display device is provided with a touch panel, and the state of the device of the programmable controller can be set by the components of the display screen. For example, when a switch part is arranged as a part and the switch part is assigned to the contact of the 200th timer of the programmable controller, the contact of the 200th timer is turned on and off by pressing the switch part on the display screen. Can do.
[0010]
[Problems to be solved by the invention]
As described above, various display screens can be created by arranging various components on the editing screen of the screen data creation device.
[0011]
Such a part has a plurality of image states to represent the function of the part. For example, the switch component is provided with an image state indicating ON of the switch and an image state indicating OFF. For example, switch on is represented by a flat image state, and switch off is represented by a concave image state. In the case of a lamp component, an image state indicating that the lamp is on and an image state indicating that the lamp is off are prepared. For example, lamp on is represented by a bright image state and lamp off is represented by a dark image state. The lamp switch component is provided with an image state indicating switch on, an image state indicating switch off, an image state indicating lamp on, and an image state indicating lamp off.
[0012]
In the conventional screen data creation device, various images are prepared in advance for each component. When creating a display screen, the user can select an image of an arbitrary part from parts images prepared in advance for the part to be displayed on the display screen, and place the image on the editing screen.
[0013]
In addition, for example, bitmap format images created and edited using commercially available image editing software are imported as image data into the screen data creation device, and placed on the editing screen as part images when creating the display screen. Can do.
[0014]
As described above, in the conventional screen data creation device, when a display screen is created, an image of a part prepared in advance or an arbitrary image captured from the outside can be arranged on the display screen.
[0015]
However, when an image created and edited by the user is arranged as a component on the display screen, the image is not originally created as a component of the display device, so components such as switches and lamps that the user recognizes The image is displayed in a very different form. For example, a landscape image can be arranged as a component on the display screen, but the landscape image simply appears to be displayed on the display screen. It cannot be recognized that it has the functions of the parts.
[0016]
Since the display device plays a role similar to that of components such as push button switches that exist on a general control panel, the components placed on the display screen of the display device should be close to the image of the components on the control panel. Is desirable.
[0017]
Therefore, it is desired to display an arbitrary image in a form that can be easily recognized as a component having a predetermined function.
[0018]
An object of the present invention is to provide an image creating apparatus, an image creating method, and a recording medium on which an image creating program is recorded, which enables an arbitrary image to be displayed in a form that can be easily recognized as a part having a predetermined function.

[0067]
First, component image creation processing in the image creation program will be described with reference to FIGS. 8 and 11. Here, it is assumed that an image of a part is created using an arbitrary image after determining the arrangement coordinates of the part on the editing screen 321 in FIG.
[0068]
First, in the screen data creation device 300, when the user designates an image by operating the input device 330, the CPU 350 takes in the designated image (hereinafter referred to as an original image) as image data (step S1). As the original image, for example, an image in a bitmap format taken from an external device such as a digital camera, an image created by drawing software, or the like can be designated. These images are recorded in advance on a recording medium, for example, read from the recording medium driving device 370, or stored in the external storage device 380 in advance. Moreover, it can also designate from the image of the components prepared beforehand by the components list screen 323 shown in FIG. Here, the original image 600 shown in FIG. 11A is captured as image data.
[0069]
Next, it is determined whether or not the user has instructed to change the image (step S2). When an instruction to change the image is given, a part type selection instruction is accepted (step S3). The user uses the input device 330 to select the type of component such as a switch component, a lamp component, or a lamp switch component. Here, a lamp switch component is selected.
[0070]
When the user gives an instruction to select the type of component, the CPU 350 duplicates the original image corresponding to the plurality of image states of the selected type of component (step S4). When the switch part is selected, the original image is duplicated in two corresponding to two image states, and when the lamp part is selected, two original images are corresponding to the two image states. When the lamp switch component is selected, the original image is duplicated into four corresponding to the four image states. Here, as shown in FIG. 11B, the original image 600 is duplicated into four original images 601, 602, 603, and 604.
[0071]
Next, the CPU 350 creates a plurality of image states by changing the copied original image (Step S5). As the original image changing process, an image composition process shown in FIG. 9 or an image processing process shown in FIG. Here, the four image states 611, 612, 613, and 614 shown in FIG. 11C are obtained by performing change processing on the four original images 601, 602, 603, and 604 in FIG.
[0072]
The image state 611 corresponds to the lamp being turned on and is represented by a bright image. The image state 612 corresponds to the lamp being turned off and is displayed as a dark image. The image state 613 corresponds to the switch being turned on and is displayed as a bright image with a shadow. The image state 614 corresponds to the switch being turned off, and is displayed as a dark image with a shadow.
[0073]
Next, the CPU 350 stores the obtained plurality of image states and the arrangement coordinates of the parts in the external storage device 380 (step S6). Here, information representing the four image states 611 to 614 in FIG. 11C is stored in the external storage device 380. In this case, the information representing the plurality of image states includes the image size, image data, and the like, and is stored as, for example, a bitmap format image data file, a JPEG format image data file, and a GIF format image data file. The
[0074]
The image of the part thus created is automatically arranged on the editing screen 321 in FIG. 7 based on the predetermined arrangement coordinates. Further, the image of this part is registered in the parts list screen 323 of FIG. 5 and can be used by the screen data creation program.
[0075]
Next, the image composition processing in the component image creation processing of FIG. 8 will be described with reference to FIGS. 9 and 12.
[0076]
First, the CPU 350 accepts selection of another image to be synthesized with the original image (step S11). The user selects an arbitrary image from a plurality of images prepared in advance. For example, an arbitrary switch frame is selected from a plurality of switch frame lists prepared in advance. Here, a frame 700 shown in FIG. 12A is selected.
[0077]
Next, the CPU 350 performs a resizing process for changing the size of the other selected image so as to match the size of the original image (step S12). Here, as shown in FIG. 12B, the frame 700 is enlarged or reduced in accordance with the size of the original image 601. The frame width t of the frame 700 can also be set. The frame width t is not changed by the enlargement or reduction of the frame 700.
[0078]
Further, the CPU 350 performs a composition process for compositing the original image with another image that has been resized (step S12). Here, a frame 700 is combined with the original image 601 as shown in FIG. Thereby, the image composition process ends.
[0079]
Next, an image processing process in the component image creation process of FIG. 8 will be described with reference to FIGS. 10, 13, and 14.
[0080]
First, the CPU 350 accepts a selection of a processing method (step S21). In this case, the user selects an original image processing method. As processing methods, there are a method of changing the brightness (brightness) of the original image, a method of changing the hue (color) of the original image, a method of blurring the original image, a method of changing the background, and a method of adding a shadow to the original image. . As another example of the processing method, there are a process in which the inside of the frame appears to be recessed, a process in which the inside of the frame appears to protrude, and the like.
[0081]
Further, the CPU 350 executes the selected processing method (step S22). In the example of FIG. 13A, the original image 601 is processed into a bright image 621, and in the example of FIG. 13B, the original image 602 is processed into a dark image 622. Further, in the example of FIG. 14B, processing for adding a shadow 633 to the original image 603 is performed. In the example of FIG. 14A, the original image 601 is not processed. In this way, the image processing process ends.
[0082]
With the above component image creation processing, it is possible to display an arbitrary image in a form that can be easily recognized as a component having a predetermined function. Therefore, the degree of freedom of display screen creation by the screen data creation device 300 is increased.
[0083]
Not limited to the above example, the image creation program can create images of various components using arbitrary images. For example, in the case of a switch component, the original image is displayed in a frame that appears to be recessed inside as an image state corresponding to the switch being turned on, and the original image is displayed in a frame that appears to protrude inside as an image state corresponding to the switch being turned off. Display an image. Further, the background of the original image is set to a transparent color as an image state corresponding to the switch being turned on, and the background of the original image is set to an opaque color as the image state corresponding to the switch being turned off.
[0084]
In the case of a lamp component, the original image is displayed in a bright color as an image state corresponding to the lamp being turned on, and the original image is displayed in a dark color as an image state corresponding to the lamp being turned off. Also, the original image is displayed in red as an image state corresponding to the lamp being turned on, and the original image is displayed in black as the image state corresponding to the lamp being turned off. Further, the original image is clearly displayed as the image state corresponding to the lamp being turned on, and the original image is displayed in a blurred manner as the image state corresponding to the lamp being turned off.
[0085]
Note that the plurality of image states of a component are not limited to two or four, and can have any number of image states depending on the type of component. For example, a component that displays time has 12 image states.
