Note that the technical scope of the present invention is not limited to the following embodiments.First Embodiment.FIG. 1 is a diagram illustrating a configuration of a display control system 100 according to a first embodiment. The display control system 100 includes a controller 1 and a display device 2.The control device 1 includes a storage device 11, an arithmetic device 12, and an input / output interface unit 13. the control device 1 is connected to the display device 2 via a transmission line, and provides screen display data to be displayed to the display device 2 through the connected display device 2. The control device 1 can be a numerical control device, for example.The storage device 13 has a function of storing information to be used by the control device 1, and includes a setting data storage unit 111. The setting data storage unit 111 stores a plurality of pieces of setting data that are different for each type of the display device 2. The setting data indicates a setting condition when screen display display data is supplied to the display device 2. The storage device 11 is, for example, a nonvolatile or volatile semiconductor memory such as a random access memory (RAM), a read only memory (ROM), a flash memory, an erasable programmable read only memory (EPROM), or an electrically EPROM (EEPROM), a magnetic disk, a floppy disk, an optical disk, a compact disk, a mini disk, a digital versatile disk (DVD), or the like.FIG. 2 is a table illustrating an example of information stored in the setting data storage unit 111 illustrated in FIG. 1. FIG. 2 illustrates multiple pieces of setting data. Each of the plurality of pieces of setting data illustrated in FIG. 2 includes, as setting items, a resolution of the display device 2, a data width (data width) of the screen display data, a scan direction when the display device 2 displays the screen display data, and a driving system of the display device 2. Resolutions of the setting data #1 and setting data #4 are video graphics array (VGA) (640×480), resolutions of the setting data #2, setting data #5, and setting data #7 are extended graphics array (XGA) (1024x768), and resolutions of the setting data #3 and setting data #6 are super extended graphics array (SXGA) (1280×1024). Further, data widths of the setting data #1 to setting data #3 and setting data #5 to setting data #7 are eight bits, and a data width of the setting data #4 is six bits. The scanning directions of the setting data #1 to setting data #3 and setting data #5 to setting data #7 are a forward direction, and a scanning direction of the setting data #4 is a backward direction. A driving system of the setting data #1 is line common inversion, driving systems of the setting data #2 to #4 and setting data #6 are dot inversion, a driving system of the setting data #5 is dot inversion 1×1, and a driving system of the setting data #7 is dot inversion 1×2.The arithmetic device 12 includes a control unit 121 that controls an operation of the control device 1. The arithmetic device 12 may be dedicated hardware or a central processing unit (CPU). In a case where the arithmetic device 12 is dedicated hardware, the arithmetic device 12 may be a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), or a combination thereof. The control unit 121 performs setup processing of selecting setting data to be used for controlling the display device 2. The control unit 121 performs the setup processing of selecting the setting data to be used for controlling the display device 2 by allowing an operator to select the setting data to be used by using a screen display as illustrated in FIGS. 3 and 4. FIG. 3 is a view illustrating a first example of a setting screen display to be displayed on the display device 2 by the controller 1 illustrated in FIG. 1. FIG. 4 is a view illustrating a second example of the setting screen display to be displayed on the display device 2 by the controller 1 illustrated in FIG. 1.The controller 1 may provide the display device 2 with screen display display data including a test pattern for determining whether setting data corresponding to the screen display data is appropriate for the display device 2 displaying the screen display data or not. For example, the screen display display data of the first example illustrated in FIG. 3 includes: a test pattern P such as a color display pattern, a gradation pattern, a flicker check pattern, and an extreme scope check pattern; and a message screen display MS 1 that prompts the operator to perform a predetermined operation at a time of receiving screen display data that is adapted to the display device 2. The message screen MS1 shown in FIG. 3 includes a message "When the pattern on the test screen is correctly displayed, press ENTER button", and prompts the operator to perform a predetermined operation when the operator determines that the display is correct.Further, the screen display data of the second example shown in FIG. 4 includes, in addition to the test pattern P and a message screen MS2, a driving system test pattern TP including a pattern TP-1 which is correctly displayed and a "killer" pattern TP-2 in which an abnormality occurs on the display when the driving system included in the setting data corresponding to the screen display data coincides with the driving system of the display apparatus 2 which displays the screen display data. The message screen MS 2 illustrated in FIG. 4 displays a message such as "It is normal when B is flickering more than A. Press the ENTER button", and prompts the operator to perform a predetermined operation when the pattern TP- 1 is correctly displayed while an abnormality occurs in the display of the "killer" pattern TP- 2. In such an operation, by displaying the driving system test pattern TP illustrated in FIG. 4, in a case where the driving system is different, even when the resolution, the data width, and the like are identical as in the setting data #5 and setting data #7 of FIG. 2, the display apparatus 2 for which setting data #5 is appropriate and the display apparatus 2 for which setting data #7 is appropriate can be identified, and the setting data can be selected more accurately.The control unit 121 may allow the operator to select the setting data to be used when the screen display data is supplied to the display device 2 by sequentially transmitting, to the connected display device 2, a plurality of pieces of screen display data individually corresponding to the plurality of pieces of setting data stored in the setting data storage unit 111, and causing the display device 2 to display the screen display as in FIGS. 3 and 4 to obtain operation information from the operator.The input / output interface unit 13 includes a data output unit 131 that outputs data from the controller 1 and a data input unit 132 through which data is input to the controller 1, and the input / output interface unit 13 is an input / output interface for data for the controller 1. For each of the data output unit 131 and the data input unit 132, it is possible to use, for example: parallel RGB, which is an interface corresponding to a system for transmitting screen display data by a parallel red-green-blue (RGB) signal by using a complementary metal oxide semiconductor (CMOS) circuit; LVDS, which is an interface corresponding to a system for transmitting screen display data by a low-amplitude high-speed differential signal (low-amplitude high-speed differential signal), which is called low voltage differential signaling (LVDS), by using a differential circuit; and a unidirectional general-purpose communication interface such as serial communication.The display device 2 includes a display unit 21, an operation unit 22, and an input / output interface unit 23. the display unit 21 displays screen display data input from the control device 1. The operation unit 22 is an operation button physically provided on the display device 2, a touch sensor, or the like. In a case where the display device 2 includes the touch sensor, the operation unit 22 may obtain operation information by using a key button. The input / output interface unit 23 includes a data output unit 231 that outputs data from the display device 2 and a data input unit 232 through which data is input to the display device 2, and the input / output interface unit 23 is an input / output interface for data for the display device 2. in the first embodiment, the data output unit 231 outputs operation information to the control device 1, and screen display data from the control device 1 is input to the data input unit 232. For each of the data output unit 231 and the data input unit 232, it is possible to use parallel RGB, LVDS, or a general-purpose unidirectional communication interface such as serial communication. In the first embodiment, the data output unit 131 of the controller 1 and the data input unit 232 of the display device 2 are connected to form a unidirectional communication interface for transmitting data from the controller 1 to the display device 2.FIG. 5 is a flowchart for explaining an operation of the control device 1 illustrated in FIG. 1, and when the display device 2 is connected to the control device 1 and the setup processing is started, the control unit 121 of the control device 1 sequentially reads out one of a plurality of pieces of setting data stored in the setting data storage unit 111 (step S 101). For example, in a case where the plurality of pieces of setting data illustrated in FIG. 2 are stored in the setting data storage unit 111, the control unit 121 may sequentially read out the setting data from above.The control unit 121 transmits screen display display data to the display device 2 via the data output unit 131 based on the read setting data (step S 102). The control unit 121 waits for a predetermined period of time, and determines whether or not there is operation information indicating confirmation within this period of time (step S 103).When the operation information indicating confirmation is not input from the display device 2 (step S 103: NO), the control unit 121 repeats the processing of step S 101. If the setting data is not suitable for the display device 2, correct display is not performed, and the operator cannot perform confirmation operation. In this case, the control unit 121 of the control device 1 reads out setting data that has not yet been read, and transmits screen display data generated based on different setting data to the display device 2.When the operation information indicating confirmation is input from the display device 2 (step S 103: YES), the control unit 121 selects setting data to be used based on the operation information (step S 104). More specifically, the control unit 121 selects, as setting data to be used in the control of the display device 2, the setting data corresponding to the screen display data displayed on the display device 2 when the operation information is received.FIG. 6 is a flowchart for explaining an operation of the display device 2 illustrated in FIG. 1, and the display device 2 determines whether or not screen display data is received from the control device 1 (step S 201). When the screen display display data is received (step S 201: YES), the display unit 21 of the display device 2 displays the received screen display data (step S 202). When the screen display display data is not received (step S 201: NO), the processing of step S 202 is omitted. Subsequently, the operation unit 22 determines whether or not an operation by the operator has been received (step S 203).When the operation has been received (step S 203: YES), the operation unit 22 transmits operation information to the control device 1 based on the received operation (step S 204). When the operation has not been received (step S 203: NO), the display unit 21 repeats the processing of step S 201.When the controller 1 performs the operation illustrated in FIG. 5 and the display device 2 performs the operation illustrated in FIG. 6, thereby sequentially transmitting the screen display data corresponding to each of the plurality of pieces of setting data to the display device 2, the display device 2 displays the received screen display data on the display unit 121. In addition, the controller 1 waits for operation information from the display device 2 for a predetermined period of time. the screen display data transmitted from the controller 1 includes: a test pattern for determining whether setting data corresponding to the screen display data is appropriate for the display device 2 displaying the screen display data or not; and a message screen display prompting an operator to perform a predetermined operation at a time of receiving the screen display data appropriate for the display device 2. After the screen display display data is displayed on the display unit 121, when the operator views the displayed test pattern and determines that the test pattern is correctly displayed, the operator performs the operation displayed on the message screen display. For example, the operator who has seen the screen display display shown in FIGS. 3 and 4 presses the ENTER button when the operator has determined that the screen display display is being displayed correctly. When the operator performs the predetermined operation, the display device 2 outputs, to the control device 1, operation information indicating this operation. When there is operation information indicating the confirmation within the predetermined time period, the controller 1 selects the setting data to be used for controlling the display device 2 based on the operation information. Further, when the screen display display data is not suitable for the display device 2, the operator does not execute the confirmation operation. Therefore, within the predetermined period of time, the control device 1 does not obtain operation information indicating the confirmation, reads out new setting data, and transmits screen display data based on the next setting data to the display device 2.As described above, the control apparatus 1 according to the first embodiment includes: the setting data storage unit 111 that stores a plurality of pieces of setting data, the setting data including a resolution of the display apparatus 2 and at least one of a scan direction when the display apparatus 2 displays screen display data and / or a driving system for the display apparatus 2, and the setting data being different according to a type of the display apparatus 2 and indicating a setting condition when the screen display data is supplied to the display apparatus 2; The control unit 121 performing setup processing, which includes: sequentially transmitting to the connected display device 2 a plurality of pieces of screen display data individually corresponding to a plurality of pieces of setting data; causing the display device 2 to display the message screens MS 1 and MS 2 prompting the operator to perform a predetermined operation at a time of receiving screen display data suitable for the display device 2; and selecting setting data to be used based on the operation information for the message screens MS 1 and MS 2. Note that in the first embodiment, the setting data includes the resolution of the display device 2, the data width of the screen display data, the scan direction when the screen display data is displayed, and the driving system of the display device 2, but the setting data does not necessarily include all of these setting items. It is sufficient that the resolution and at least one of the scan direction or the driver system are included. With the control device 1 having the above-described configuration, it is possible to set the screen display display differently for each display device 2 without complicating the device configuration. In particular, the display device 2 according to the control device 1 allows the operator to determine whether or not the screen display is correct. As long as the operation of the operator can be received by the operation unit 22, it is not necessary to provide an additional function such as a circuit for determining whether or not the screen display is correct.Further, in the method of using a dedicated line for each display device 2 conventionally used in a numerical controller having image processing functionality, a signal line for identifying the type of the display device 2 is provided in the dedicated line, and the numerical controller needs to read information on the signal line to identify the type of the display device 2 to be connected. In this method, a dedicated line is required for each type of display device 2, and it is necessary to increase the number of signal lines for identification as compared with a general-purpose image transmission line. Therefore, there has been a problem that the number of signals in the line and the number of terminals of a connector for connecting the line have increased. According to the control apparatus 1, it is possible to identify the type of the display apparatus 2 to be connected without using a dedicated line. Therefore, as lines prepared for the display device, lines of one type can be used in common, and a terminal for determining the type of the display device 2 can be omitted.Second Embodiment.FIG. 7 is a diagram illustrating a configuration of a display control system 200 according to the second embodiment. The display control system 200 includes a controller 1- 1 and the display device 2. detailed description of parts similar to those of the first embodiment will be omitted below, and parts different from those of the first embodiment will be mainly described.The control device 1- 1 includes a storage device 11- 1, an arithmetic device 12- 1, and the input / output interface unit 13. the control device 1- 1 is connected to the display device 2 via a transmission line, and provides an ON / OFF signal to the display device 2 and screen display data to be displayed by the connected display device 2.The storage device 11- 1 includes a setting data storage unit 111- 1. The setting data storage unit 111- 1 stores a plurality of pieces of setting data that are different for each type of the display device 2. FIG. 8 is a table illustrating an example of information stored in the setting data storage unit 111- 1 illustrated in FIG. 7. The setting data stored in the setting data storage unit 111- 1 also includes signal timing as setting items in addition to resolution, data width, scanning direction, and driving system. The signal timing indicates a transmission timing of the screen display data.The arithmetic device 12- 1 includes a control unit 121- 1. In addition to the function of the control unit 121 according to the first embodiment, the control unit 121- 1 controls a timing of transmitting to the display device 2 an ON signal for activating the display unit 21 of the display device 2, an OFF signal for stopping the display unit 21, and screen display data on the basis of the signal timing included in the setting data. The control unit 121- 1 has a functionality of controlling a time period for displaying the screen display data on the display device 2 by transmitting the ON signal and the OFF signal to the display device 2. The control unit 121- 1 can change the time period during which the operator can operate by controlling the time period during which the screen display data is displayed on the display device.FIG. 9 is a view for explaining a control timing of the control device 1- 1 illustrated in FIG. 7. The controller 1- 1 may control a time duration Δt 1-1, during which display of screen display data based on setting data #1 is ON, and a time duration Δt 2-1, from when display of the screen display data based on setting data #1 is OFF to the time when display of the screen display data based on setting data #2 is turned ON, by controlling, based on the signal timing included in the setting data, a time at which screen display data generated based on the setting data and the ON signal are transmitted and a timing at which the OFF signal is transmitted. Similarly, the controller 1- 1 may control, for the setting data #2, a time duration Δt 1-2 during which display is ON and a time duration Δt 2-2 during which display is OFF, and may control, as for setting data #3, a time duration Δt 1-3 during which display is ON and a time duration Δt 2-3 during which display is OFF. Here, in the signal timing of FIG. 8, the time period during which each part of the setting data is ON is set as A, B, and Bα in accordance with the setting data, but the time period during which each part of the setting data is OFF may be additionally set.FIG. 10 is a flowchart for explaining an operation of the control apparatus 1- 1 illustrated in FIG. 7. Note that parts similar to those in FIG. 5 are denoted by identical reference numerals, and detailed description thereof will be omitted.When the display device 2 is connected to the controller 1- 1, the control unit 121- 1 of the controller 1- 1 sequentially reads out setting data. (Step S 101). The control unit 121-1 transmits the ON signal of the display unit 21 of the display device 2 and screen display data based on the read setting data to the display device 2 (step S102-1). Steps S 103 and S 104 are similar to those of FIG. 5. When there is no operation information indicating confirmation within a predetermined period of time (step S 103: NO), the control unit 121- 1 transmits the OFF signal of the display unit 121 of the display device 2 to the display device 2 (step S 105), and returns to the processing of step S 101.As described above, in the second embodiment, the setting data includes the signal timing indicating the transmission timing of the screen display data as the setting item. While the setting items such as the resolution, the data width, the scanning direction, and the driving system are used as setting conditions when the screen display data is generated, the transmission timing is used as a provision condition from when the generated screen display data is provided to the display device 2. Based on the signal timing, the control unit 121- 1 of the control device 1- 1 determines a transmission timing of the screen display data for each piece of the setting data. Therefore, the operator can determine whether or not the transmission timing of the screen display display data is appropriate for the display device 2. Depending on a type of the display device 2, an abnormality may occur in the display when a restriction regarding the image display data and the ON signal for controlling start of power supply is not satisfied. In the second embodiment, by adding the signal timing to the setting data, it is possible to determine whether or not the setting data is also suitable for such a display device 2.Third Embodiment.FIG. 11 is a diagram illustrating a configuration of a display control system 300 according to a third embodiment. The display control system 300 includes a controller 1- 2 and the display device 2. detailed descriptions of parts similar to those of the first embodiment will be omitted below, and parts different from those of the first embodiment will be mainly described.The control apparatus 1-2 includes a storage apparatus 11-2 and an arithmetic apparatus 12-2. The storage device 11- 2 includes a held data storage unit 112 (held data storage unit) in addition to the set data storage unit 111. The reservation data storage unit 112 has a function of saving selected setting data. The lead data storage unit 112 initially stores NULL.The arithmetic device 12- 2 includes a control unit 121- 2. The control unit 121- 2 has a functionality of performing device processing, similar to the control unit 121, and stores setting data selected by the device processing into the reservation data storage unit 112. In a case where the setting data at a time of activation is stored in the holding data storage unit 112, the control unit 121- 2 may control the display device 2 using the stored setting data and omit the setup processing. In a case where the setting data is not held in the holding data storage unit 112, the control unit 121- 2 performs the setup processing.FIG. 12 is a flowchart for explaining an operation of the control apparatus 1- 2 illustrated in FIG. 11. The control unit 121-2 of the control apparatus 1-2 reads out lead data from the lead data storage unit 112 at the time of activation (step S106). The control unit 121-2 determines whether or not the lead data is present (step S107). When present lead data (step S 107: YES), the control unit 121- 2 selects the lead data, which is setting data stored in the lead data storage unit 112, as setting data to be used for controlling the display device 2 (step S 109), and controls the display device 2 using the selected setting data.When lead data is not present (step S 107: NO), the control unit 121- 2 performs the setup processing (step S 100). Note that the setup processing in step S 100 corresponds to the processing illustrated in steps S 101 to S 104 in FIG. 5. Since the setting data is selected when the setup processing is completed, the control unit 121- 2 stores the selected setting data in the holding data storage unit 112 (step S 110), and controls the display device 2 using the selected setting data.As described above, since the control apparatus 1- 2 according to the third embodiment includes the holding data storage unit 112 that holds the selected setting data, the selected setting data is held when the setting data is selected by performing the setup processing once. Therefore, it is not necessary to perform the setup processing each time the apparatus is started. In addition, the control unit 121- 2 controls the display device 2 in a case where the setting data is held in the holding data storage unit 112 using the held setting data, and executes the setup processing in a case where the setting data is not held in the holding data storage unit 112. Therefore, after the device processing is performed once, the device processing can be omitted, and the device processing can be performed when the display device 2 is connected for the first time. In addition, the setup processing may be performed again by deleting the setting data held in the holding data storage unit 112 when the setup processing needs to be executed, for example, when the display device 2 different from the previous display device is connected. For example, as a method of clearing and resetting the setting data held in the reservation data storage unit 112, a mechanism is conceivable in which, when a predetermined operation such as starting is performed while a certain button on the control device 1- 2 is pressed, NULL is forcibly written into the reservation data storage unit 112.Fourth Embodiment.FIG. 13 is a diagram illustrating a configuration of a display control system 400 according to a fourth embodiment. The display control system 400 includes a controller 1- 3 and the display device 2. the controller 1- 3 includes the memory device 11- 2, an arithmetic device 12- 3, and the input / output interface unit 13. Hereinafter, detailed descriptions of parts similar to those of the third embodiment will be omitted, and parts different from those of the third embodiment will be mainly described.In the third embodiment, when lead data is present in the lead data storage unit 112, the control of the display device 2 is started using the lead data as it is. In the fourth embodiment, when present in the present data storage unit 112, a procedure is passed in which screen display data is transmitted to the display device 2 based on setting data which is the present data, and the operator is allowed to confirm whether or not the screen display data is displayed correctly.FIG. 14 is a flowchart for explaining an operation of the control apparatus 1- 3 illustrated in FIG. 13. Steps S106 and S107 are similar to those in Fig. 12. When present reservation data (step S 107: YES), the control unit 121- 3 transmits screen display data to the display device 2 based on the reserved setting data (step S 111). Then, the control unit 121- 3 determines whether or not there is operation information indicating confirmation within a predetermined period of time (step S 112).
