The object list shown in fig. 6 is an example, and is not limited to the object list shown in fig. 6.
The user of the terminal device 20 operates the client input device 23 to access the programmable display 10. The input data generated by operating the client input device 23 is supplied to the arithmetic unit 206 of the terminal device 20. The arithmetic unit 206 generates access data indicating an access request from the terminal device 20 to the programmable display 10 based on the input data. The access data generated by the arithmetic unit 206 is transmitted to the programmable display 10 via the communication unit 210 and the communication network 2. The client-specific data acquisition unit 112 acquires access data indicating an access from the terminal device 20 via the server unit 116 (step S102).
When the terminal device 20 accesses the programmable display 10, the client specific data acquisition unit 112 acquires client specific data indicating specific data of the client display device 22 (step S103). The client specific data acquisition unit 112 acquires the screen size of the client display device 22 as client specific data. The acquired client specific data is stored in the server storage unit 104.
The arithmetic unit 106 determines whether or not the display screen data generated in step S101 can be converted into screen image data based on the client unique data acquired in step S103 (step S104). In other words, the arithmetic unit 106 determines whether or not the display screen data can be used as the client screen data.
If it is determined in step S104 that the display screen data can be converted into the screen image data (step S104: Yes), the screen image generation unit 110 generates the screen image data that can be displayed on the client display device 22 based on the display screen data and the client unique data (step S105). The screen image generation unit 110 generates screen image data matching the screen size of the client display device 22 from the display screen data based on the screen size of the client display device 22 included in the client unique data.
If it is determined in step S104 that the display screen data cannot be converted into the screen image data (No in step S104), the process of generating the client screen data is terminated.
After the screen image data is generated by the screen image generation unit 110, the server unit 116 transmits the generated screen image data to the terminal device 20 (step S106). The screen image data includes object data representing an object of the server screen. In embodiment 1, screen image data includes a screen image generated from a server screen and an object corresponding to the screen image.

The user selects an object desired to be displayed on the client display device 22 based on the screen image data displayed on the client display device 22. The user operates the client input device 23 to select at least one object among a plurality of objects included in the screen image displayed on the client display device 22. The selected object may be single or plural.
When the client input device 23 includes a touch sensor provided on the display screen of the client display device 22, the user selects an object by touching a display area in which the object is displayed on the display screen of the client display device 22.
If the client input device 23 is operated, the input data generated by the client input device 23 is supplied to the arithmetic section 206 of the terminal device 20. The arithmetic unit 206 determines whether or not input data to be selected from the screen image is generated (step S108).
The calculation unit 206 compares the object data transmitted from the programmable display 10 and stored in the client storage unit 204 with the input data generated by the client input device 23, and determines whether or not input data for selecting an object is generated. When determining that at least a part of the area touched by the user on the display screen of the client display device 22 matches at least a part of the display area of the object, the arithmetic unit 206 determines that the object is selected. On the other hand, when determining that the area touched by the user on the display screen of the client display device 22 does not match the display area of the object, the calculation unit 206 determines that the object is not selected.
If it is determined in step S108 that input data of a selected object has been generated (Yes in step S108), the display control unit 202 causes only the selected object to be displayed on the client display device 22 (step S109).
The position data of the selected object is stored in the client storage unit 204. The position data of the object includes coordinate data of a display area in which the object is displayed on the display screen of the client display device 22.
If it is determined in step S108 that the input data to be selected has not been generated (No in step S108), the process of step S110 is executed.
The editing of the screen image data in the terminal device 20 includes editing of the object data. The user edits the object data by operating the client input device 23 while referring to the object data displayed on the client display device 22.
Fig. 7 is a schematic diagram showing a method of selecting an object according to embodiment 1. As shown in fig. 7, the screen image data is displayed on the client display device 22.

The client screen generating unit 114 generates client screen data to be displayed on the client display device 22 based on the screen image data and the client specific data included in the object data edited by the terminal device 20 (step S112). The client screen generating unit 114 generates client screen data based on the screen image data including the edited object list transmitted from the terminal device 20 and the client specific data including the screen size of the client display device 22.
The server storage unit 104 stores the generated client screen data together with client specific data of the client display device 22 that displays the client screen data.
Fig. 12 is a schematic diagram showing the server storage unit 104 according to embodiment 1. As shown in fig. 12, the programmable display 10 performs data communication with a plurality of terminal devices 20(20A, 20B, 20C). The client specific data of the plurality of terminal devices 20 and the client screen data displayed on the client display device 22 of the terminal device 20 are stored in the server storage unit 104 in association with each other. The server storage unit 104 stores link data in which client unique data of the plurality of terminal devices 20 and client screen data of the terminal devices 20 are associated with each other. The server storage unit 104 stores client screen data a associated with the terminal device 20A, client screen data B associated with the terminal device 20B, and client screen data C associated with the terminal device 20C.
The client screen data generated by the programmable display 10 is transmitted to the terminal device 20. The server unit 116 transmits the client screen data generated by the client screen generating unit 114 and stored in the server storage unit 104 to the terminal device 20 via the communication network 2 (step S113).
The server unit 116 can transmit client screen data associated with the terminal device 20 to the terminal device 20 based on the client unique data. The client display device 22 of the terminal device 20 displays the client screen data generated by the programmable display 10 and transmitted from the programmable display 10.
The terminal device 20 can access the programmable display 10 and specify client screen data associated with the client-specific data. For example, the terminal device 20A can access the server storage unit 104 via the communication network 2, specify the client screen data a associated with the client unique data of the terminal device 20A, and acquire the client screen data a.
After the client screen data is generated and transmitted to the terminal device 20, the arithmetic unit 106 of the programmable display 10 determines whether or not the object data edited by the terminal device 20 is reflected in the display screen data (step S114).
If it is determined in step S114 that the edited object data is not to be reflected in the display screen data (No in step S114), the process of generating the client screen data ends. If it is determined in step S114 that the edited object data is to be reflected in the display screen data (step S114: Yes), the display screen generation unit 108 generates the display screen data based on the object data edited by the terminal device 20. That is, the display screen generation unit 108 changes the display screen data based on the edited object data (step S115).
Fig. 13 is a schematic diagram showing an operation of the control system 1 according to embodiment 1. Object data including an edited object list edited by the terminal device 20 is stored in the server storage unit 104 of the programmable display 10. The display screen generation unit 108 of the programmable display 10 edits the display screen data based on the edited object list. The display screen generation unit 108 generates screen data for the server based on the position of the changed object or the size of the changed object. The display screen data is changed based on the edited object list, thereby generating display screen data reflecting the edited object data. The display control unit 102 causes the server display device 12 to display the edited display screen data in which the edited target data is reflected.
As described above, according to embodiment 1, the programmable display 10 acquires client specific data indicating specific data of the client display device 22. Therefore, the programmable display 10 can generate client screen data that can be displayed by the client display device 22 based on the display screen data that can be displayed by the server display device 12 and the client unique data. The client screen data generated by the programmable display 10 is transmitted to the terminal device 20 via the communication network 2, so that the user can generate the client screen data by using the display screen data of the programmable display 10 using the terminal device 20. The user can continue to use the existing display screen data to generate the client screen data without using drawing software. Since the client screen data can be generated based on the display screen data without newly creating the client screen data using drawing software, the number of processes for creating the client screen data is reduced, and the burden on the user is reduced.
Further, according to embodiment 1, the programmable display 10 generates screen image data from the display screen data based on the client unique data, and transmits the generated screen image data to the terminal device 20. The screen image data edited by the terminal device 20 is transmitted from the terminal device 20 to the programmable display 10. The programmable display 10 generates client screen data for display on the client display device 22 based on the edited screen image data and the client unique data. Therefore, the programmable display 10 can generate client screen data that matches the user's intention after editing the screen image data using the terminal device 20.
In addition, according to embodiment 1, the editing of the screen image data in the terminal device 20 includes editing of the object data. Accordingly, the programmable display 10 can generate client screen data containing an object whose position or size conforms to the user's intention.
In addition, according to embodiment 1, the programmable display 10 generates display screen data based on the object data edited by the terminal device 20. Therefore, the object on the server screen can be edited using the terminal device 20. Therefore, the man-hours for editing the display screen data are reduced.
Further, according to embodiment 1, the client screen generating unit 114 of the programmable display 10 generates the client screen data based on the client specific data and the display screen data acquired by the client specific data acquiring unit 112 after the client specific data acquiring unit 112 acquires the access data transmitted from the terminal device 20. That is, the programmable display 10 generates client screen data regarding the accessed terminal device 20, and does not generate client screen data regarding terminal devices 20 that have not been accessed. Therefore, for example, it is possible to suppress unnecessary data from being stored in the server storage unit 104, and the programmable display 10 can efficiently create client screen data.
Further, according to embodiment 1, the terminal device 20 includes an image editing unit 208 that edits the screen image data based on the input data input from the client input device 23. Therefore, the user can efficiently create screen image data by operating the client input device 23 to follow the display screen data.
Further, according to embodiment 1, the editing of the screen image data includes editing of the object data. Therefore, the user can efficiently create arbitrary screen image data by editing the object without performing a complicated operation.
Fig. 14 is a flowchart showing the operation of the control system 1 according to embodiment 2. In embodiment 2, an operation of the control system 1 will be described in the case where, in the control system 1 having the same configuration as that of embodiment 1, selection target data indicating selected target data among a plurality of target data supplied to the terminal device 20 is stored in the client storage unit 204 of the terminal device 20, and new screen image data is generated using the selection target data.
As in embodiment 1, the programmable display 10 performs the processing from step S201 to step S207. The processing from step S201 to step S207 is the same as the processing from step S101 to step S107 in embodiment 1, and therefore, the description thereof is omitted.
After the process of step S207, if the user operates the client input device 23, the input data generated by the client input device 23 is supplied to the arithmetic unit 206 of the terminal device 20. The arithmetic unit 206 determines whether or not input data to be selected from the screen image is generated (step S208).
If it is determined in step S208 that the input data to be selected has not been generated (No in step S208), the process of step S210 is performed.
When it is determined in step S208 that input data to be selected is generated (Yes in step S208), the arithmetic unit 206 causes the client storage unit 204 to store selection target data indicating selected target data among the plurality of target data supplied to the terminal device 20 (step S209).
Fig. 15 is a schematic diagram showing a storage method of selection targets according to embodiment 2. As shown in fig. 15, the screen image data is displayed on the client display device 22. The plurality of objects 32, 33, 34, 35, 36, 37 are displayed on the client display device 22.
The character data 40 indicating "please select an object to be saved" which can store the object is displayed on the client display device 22. The user operates the client input device 23 to select an arbitrary object from the plurality of objects 32, 33, 34, 35, 36, and 37 displayed on the client display device 22. As shown in fig. 15, when the object 32 indicating the character and the object 33 indicating the bit status indicator lamp are selected, the display control unit 202 causes the frame 38 surrounding the selected object 32 and the frame 38 surrounding the object 33 to be displayed on the client display device 22. Selection object data indicating the selected objects 32 and 33 is stored in the client storage unit 204.
The arithmetic unit 206 determines whether or not to display other screen image data on the client display device 22 (step S210).
If it is determined in step S210 that the other screen image data is to be displayed on the client display device 22 (step S210: Yes), the other screen image data different from the image data shown in fig. 15 is displayed on the client display device 22, and the processing from step S204 to step S209 is performed. That is, the process of selecting an object from another screen image is performed. Selection object data indicating the selected object is stored in the client storage unit 204. Selection object data representing a plurality of selection objects is stored in the client storage unit 204.
If it is determined in step S210 that the other screen image data is not to be displayed on the client display device 22 (No in step S210), the arithmetic unit 206 determines whether or not to generate new screen image data (step S211).
When it is determined in step S211 that No new screen image data is to be generated (No in step S211), the new screen image data generation process is terminated.
If it is determined in step S211 that new screen image data is to be generated (Yes in step S211), the image editing unit 208 performs a process of placing the selection target stored in the client storage unit 204 in the new screen image (step S212).
Fig. 16, 17, and 18 are schematic diagrams illustrating a method of arranging selection objects according to embodiment 2. As shown in fig. 16, the screen image data is displayed on the client display device 22. When the "call save target" button is selected, a display area of "list of saved targets" is formed in a part of the display screen of the client display device 22 as shown in fig. 17. Objects 32 and 33, which are selection objects stored in the client storage unit 204, are displayed in the display area of the "stored object list".
The image editing unit 208 generates new screen image data based on the selection target data stored in the client storage unit 204. The user can operate the client input device 23 to place an arbitrary object on the screen image from a plurality of selection objects displayed in the display area. For example, the user selects the object 33 via the client input device 23, and moves the object 33 to a region in the display screen of the client display device 22 where the screen image is displayed. By moving the object 33 to the area where the screen image is displayed, as shown in fig. 18, the display area of the "stored object list" is deleted, and new screen image data including the object 33 is created. The image editing unit 208 can generate new screen image data as shown in fig. 18 based on the input data generated by the client input device 23 and the selection target data stored in the client storage unit 204.
The new screen image data generated in the terminal device 20 is stored in the client storage unit 204. Further, the communication unit 210 transmits the new screen image data generated in the terminal device 20 to the programmable display 10 (step S213).
The client screen generating unit 114 generates client screen data to be displayed on the client display device 22 based on the new screen image data generated in the terminal device 20 (step S214).
The client screen data generated by the programmable display 10 is stored in the server storage unit 104. In addition, the client screen data generated by the programmable display 10 is transmitted to the terminal device 20. The server unit 116 transmits the client screen data generated by the client screen generation unit 114 to the terminal device 20 via the communication network 2 (step S215).
The client display device 22 of the terminal device 20 displays the client screen data generated by the programmable display 10 and transmitted from the programmable display 10.
After the client screen data is created and transmitted to the terminal device 20, the arithmetic unit 106 of the programmable display 10 determines whether or not the object data of the new screen image data generated by the terminal device 20 is reflected in the display screen data (step S216).
If it is determined in step S216 that the target data is reflected in the display screen data (Yes in step S216), the display screen generation unit 108 changes the display screen data based on the target data of the new screen image data (step S217). The display control unit 102 causes the server display device 12 to display the display screen data generated based on the selection target data.
If it is determined in step S216 that the target data is not to be reflected in the display screen data (No in step S216), the new screen image data generation processing is terminated without changing the display screen data.
As described above, according to embodiment 2, since the selection target data is stored in the client storage unit 204, the user can arrange the selection target to an existing screen image in the terminal device 20 and generate a new screen image. By reflecting the object data of the generated new screen image data on the display screen data, the display control unit 102 can display the new display screen data on the server display device 12.
