DESCRIPTION OF THE EXECUTION FORMS The following describes embodiments and modification examples with reference to the drawings. The terms “first”, “second”, “third” and the like are used in the present disclosure only to distinguish between objects and are not intended to place the objects in a ranking order. First embodiment A manufacturing system 10 of a first embodiment is described below. Schematic configuration of the manufacturing system As illustrated in Fig. 1, the manufacturing system 10 includes a casting device 12, a control device 14, and a sensor 16. The casting device 12 represents a production line 12 for manufacturing a product 20 from a material 18. The casting device 12 includes one or more devices for manufacturing the product 20. The control device 14 controls the components enclosed in the casting device 12. The control device 14 controls the components of the casting device 12 based on control information stored in a memory 24 of a control system 22. The control device 14 stores control results in the components of the casting device 12 controlled by the control device 14 in the memory 24 of the control system 22. The control information includes information about the components to be controlled, control parameters for the components, and the control results in the components. The control results include a detection result obtained from a sensor, such as a pressure sensor, corresponding to an object to be controlled. The control results include a control result of the device by the control device 14 and a control time for the device. The control information may include additional information. The control device 14 stores the control information in memory 24, where the control result and the control time are linked. Memory 24 of the control system 22 is an example of a "second memory". Sensor 16 acquires sensor information on various types of control elements related to the manufacturing process in the casting device 12. Sensor 16 is provided in various types of devices enclosed within the casting device 12 and acquires different types of information in the production line 12. For example, sensor 16 may include a temperature sensor, a pressure sensor, or an accelerometer. A sensor information acquisition system 26 includes a memory 28. The sensor information acquisition system 26 stores the sensor information acquired by sensor 16 in the memory 28. The sensor information includes measurement results of the management elements by sensor 16 and measurement times measured by sensor 16. The sensor information may include further information. The sensor information acquisition system 26 stores the management elements and measurement times by sensor 16 in conjunction with each other in memory 28 as sensor information. Memory 28 of the sensor information acquisition system 26 is an example of a "first memory". A defect registration system 30 is a system for recording information relating to a product 20 that has been identified as defective during shipping inspection, as defect information. The defect registration system 30 includes a memory 32. The memory 32 stores defect information for the product 20 identified as defective. Whether the product 20 is a non-defective product or a defective product is determined, for example, by a worker performing the inspection. The defect information includes, as information relating to the product 20, image data of the product 20 identified as defective, location data indicating a defective section in the product 20, and a registration time at which the image data and location data are recorded. The defect information may include further information.The fault registration system 30 stores the image data, the position data, and the registration time in memory 32, linked together. Memory 32 of the fault registration system 30 is an example of a "third memory". Manufacturing system 10 includes a management device 40. The management device 40 manages the production line 12 of product 20 in manufacturing system 10. The management device 40 can be configured as a programmable logic controller (PLC) or as a computing system. The computing system includes a central processing unit (CPU), a main memory device such as random access memory (RAM) and read-only memory (ROM), an input device such as a touch panel or keyboard, an output device such as a display, and an auxiliary storage device such as a hard disk. The management device 40 displays various types of screens based on the information stored in memories 24, 28, and 32 of the respective systems 22, 26, and 30. It can be said that the management device 40 operates based on the information from each of the systems 22, 26, and 30. Consequently, the management device 40 can function as an installation that encompasses the systems 22, 26, and 30. Therefore, it can also be said that the management device 40 includes memories 24, 28, and 32. The management device 40 includes a display device 42. The display device 42 shows information relating to the manufacturing system 10. The display device 42 includes an input unit 44, a display controller 46, and a display unit 48. The input unit 44 can be an input device of the computer system that forms the management device 40. The display unit 48 can be an output device of the computer system that forms the management device 40. The display control 46 controls the information acquisition, a display procedure, and the like for the display image of the display unit 48. The display control 46 causes the display unit 48 to display several screens. The screens displayed by the display unit 48 include a screen relating to error information. The display control 46 causes the display unit 48 to display a screen that includes the fault information, the sensor information corresponding to the fault information, and the control information corresponding to the fault information. In this way, by displaying the sensor information and the control information together with the fault information on one screen, fault factors for the product 20 can be easily checked. Configuration example for a casting device As shown in Fig. 2, the casting device 12 includes a sand preparation device 61, a molding device 62, a core insertion device 63, a liquid metal pouring device 64, a cooling and conveying device 65, and a post-treatment device 66. These devices 61 to 66 illustrate an example of the configuration of the casting device 12; however, the configuration of the casting device 12 is not limited to this. The units 61 to 66 of the casting device 12 perform processes in the production line 12. The processes performed by the casting device 12 include a molding process, a core insertion process, a cooling and conveying process, a molten metal pouring process, a post-treatment process, and a sand preparation process. The casting device 12 is an example of the production line 12, which encompasses a variety of processes. The sand preparation unit 61 processes molding sand used for forming a casting mold. Specifically, the sand preparation unit 61 separates and removes mixed substances from recovered sand. The sand preparation unit 61 measures the temperature, moisture content, and similar parameters of the recovered sand and adds a quantity of water proportional to the measured value. The sand preparation unit 61 further adds an additive such as bentonite and water to the recovered sand and stirs the sand, thereby kneading it to produce molding sand (kneaded sand). In the sand preparation unit 61, parameters such as CB value (a compaction value), moisture content, sand temperature, air permeability, and compressive strength are measured by sensor 16 as parameters (sensor information) that define the status of the sand preparation process.The sensor information may include measurement results from other sensors. The molding unit 62 fills the molding sand prepared by the sand preparation unit 61 into a molding box and compacts the molding sand to form a mold. The mold comprises an upper mold and a lower mold. The structure consists of upper and lower pressure plates, a mold plate, and an upper or lower box on the side. The molding unit 62 feeds the molding sand into the molding box and compresses the molding sand with the pressure plates to form the upper and lower molds. In mold unit 62, the following parameters (control information) are managed: a venting pressure, a sand hopper pressure, a compression pressure (upper mold box, lower mold box), a pressure ratio (mold pressure ratio), and a spray quantity of a mold release agent. These parameters define the status of the molding process. Venting is a process in which molding sand is poured from a sand hopper into the mold box while air is blown out of a side wall of the sand hopper. Mold unit 62 also manages the molding time, at which the mold is formed, as control information. This control information can include additional information such as a molding cycle. The core insertion device 63 installs an auxiliary form, a so-called core, in the mold to produce a casting with a hollow section. The core insertion device 63 manages the timing of the core insertion and an insertion load, i.e., a load during the installation process, as parameters (control information) that define the status of the core insertion process. The liquid metal casting device 64 melts the material 18, such as iron, to produce molten metal and pours the molten metal into the mold. The liquid metal casting device 64 manages parameters (control information) such as the pouring temperature of the liquid metal, the pouring duration, and the pouring weight, which define the status of the molten metal casting process. The control information can include the pouring duration, a material number, and the ladle number of the ladle that conveys the molten metal. The cooling and conveying unit 65 conveys the mold formed in the molding unit 62 to the liquid metal casting unit 64. The cooling and conveying unit 65 also conveys the mold into which the molten metal was poured in the liquid metal casting unit 64 while cooling the mold, disassembles the mold to remove the casting, and conveys the removed casting to the post-treatment unit 66 while continuing to cool it. The disassembled mold is fed to the sand preparation unit 61 as recovered sand. In the cooling and conveying unit 65, the cooling duration and the dismantling time for the conveyed mold are managed as parameters (control information) that define the status of the cooling and conveying process. The post-treatment unit 66 performs post-treatments such as marking the casting and sprue folding. During the post-treatment process, the product 20 (casting) undergoing post-treatment is inspected by a worker or similar person. The inspection checks for the presence or absence of a scratch or similar defect on the product 20 (casting). If a defect such as a scratch is detected on the product 20 during inspection, the worker determines that the product 20 is defective. The worker records the fault information relating to the product 20 identified as faulty in the fault recording system 30, illustrated in Fig. 1. The information recorded in the defect registration system 30 includes image data of the product 20 identified as defective, information on the type of defect, information on the location of the defect, and a registration time. The information on the type of defect includes, for example, at least one of the following defect types: sand inclusion, mold collapse, shape deviation (mold displacement), chipping, mold depression, runout, dent, crack, shrinkage, blistering (air inclusion), cold working, slag, scab, fracture, and sand burning. The information on the location of the defect is information that specifies the position of the defect within product 20 (casting). For example, regarding the location of the defect, a position (coordinate values) specified by the worker in relation to the image data of product 20 is considered information on the location of the defect. Display of information by the administrative device As shown in Fig. 1, the display controller 46 of the management device 40 causes the display unit 48 to display different types of screens based on the information stored in the memories 24, 28, and 32 of the systems 22, 26, and 30. A screen G12 displayed by the display unit 48 includes fault information 52, sensor information 54, and control information 56. The display controller 46 of the management device 40 causes the display unit 48 to display a screen that includes the fault information 52, the sensor information 54 corresponding to the fault information 52, and the control information 56 corresponding to the fault information 52. The error information 52, the sensor information 54 and the control information 56 include an administrative number specified for each administrative object as information to specify the administrative object in the casting device 12. The management object in the casting device 12 refers to an object that is processed or used in each of the facilities 61 to 66 (each process). The management object in the sand preparation process refers to the recovered sand and the molding sand. The management object in the core insertion process refers to the mold into which a core is to be inserted. The management object in the molten metal casting process refers to the molten metal and the mold. The management object in the cooling and conveying process refers to the mold and the casting. The management object in the post-treatment process refers to the casting (product). The management objects described above are examples. The respective processes are the multitude of processes that comprise production line 12. The management object is the object that is to be processed or used in each process. In the sand preparation process, the administrative number is the mold number of the mold into which the molding sand is poured. The mold number is an example of an identification number used to identify each individual mold. In the core insertion process, the administrative number is, for example, the mold number of the mold into which the core is inserted. The mold number is linked to information identifying the inserted core. In the molten metal pouring process, the administrative number is, for example, the mold number of the mold. The mold number is linked to a ladle number, which corresponds to a ladle used to pour the molten metal into the mold. In the cooling and conveying process, the administrative number is, for example, the mold number of the mold being conveyed. In the post-treatment process, the administrative number is, for example, a product number (serial number) of the casting.The product number is an example of an identification number used to individually identify the casting as a product. During the period from the sand preparation process to the cooling and conveying process, the control unit 14 controls the molds to be managed in the units 61 to 66. The status of the molding sand to be filled into the mold to be managed, and the like, is detected by the sensor 16. Therefore, the sensor information and the control information include the management number for each managed object in the casting device 12 as a production line. The management number is, for example, a mold number that corresponds to the mold used to produce the casting. The sensor information includes a mold number, a sensor detection time at which the molding sand to be filled into the mold with the aforementioned mold number was prepared, and a detection result from the sensor 16.This means that the sensor information includes the mold number as the administrative identifier for each administrative object, as well as the acquisition time and the acquisition result linked to the mold number. Similarly, the control information includes a mold number, the acquisition time of the control operation performed on the mold with the aforementioned mold number, and the control results. The control results include, for example, the internal pressure of the sand container when filling the mold with sand, a temperature detectable by the sensor as the pouring temperature of the molten metal, and a time measured as the pouring duration. In other words, the control information includes the mold number as the administrative identifier for each administrative object, as well as the acquisition time and the control result linked to the mold number. The following is an example of how to register error information in the error registration system 30. The worker records defect information relating to the casting identified as defective in the defect recording system 30. For example, the worker operates an input unit of the defect recording system 30 to display an input screen on a display unit of the defect recording system 30. The worker then uses a camera of the defect recording system 30 to take a photograph of the casting classified as defective. The worker operates the input unit to enter product-related data such as the casting model number, the casting product number, the type of defect, the location of the defect, and the like. The defect recording system 30 stores the defect information, including the various types of input data, in memory 32 based on the worker's input confirmation. The stored defect information includes the time of registration of the various data types, including image data. The display control 46 of the management device 40 causes the display unit 48 to display a screen that includes the fault information of the fault recording system 30 as well as the sensor information and the control information corresponding to the fault information. The fault information includes the registration time at which image data or similar information of the product identified as faulty is registered. The sensor information includes the management number of the managed object and the acquisition time of each managed object. The control information includes the control time of the control action performed on the managed object. The display controller 46 causes the display unit 48 to display the sensor information and control information, including the management number, corresponding to the product identified as faulty, based on the registration time. The administrative number corresponding to the product identified as defective is, for example, the administrative number of the sensor information, including the time of acquisition within a specified period based on the registration time of the fault information. Similarly, the administrative number corresponding to the product identified as defective is, for example, the administrative number of the tax information, including the tax information date within a specified period based on the registration time of the fault information. This is because there are cases where the administrative number of the sensor information or the tax information does not directly correspond to the product identified as defective. As described above, in the area from molding unit 62 to cooling and conveying unit 65, the mold produced by molding unit 62 is conveyed successively to units 61 to 66. Thus, the sensor and control information can be referenced via the mold number. However, there are cases in which the casting removed from the mold by disassembly is not marked with the mold number, the sequence of castings after disassembly differs from the sequence of mold conveyance, or similar situations arise. Since the operator can only perform the inspection once the casting, produced by pouring molten metal, has cooled sufficiently after removal from the mold, the time of inspection of the casting can be significantly delayed compared to the time of its production. Thus, the display control 46 of the management device 40 uses a predefined period, including the mold in which the registered casting was produced, as the registration time of the product (casting) identified as defective, and uses the management number of the mold that is the management object within the predefined period as the management number corresponding to the product identified as defective. This makes it possible to derive the management number of the mold in which the product was manufactured from the product after disassembly. The display control 46 then displays the sensor information and management information, including the management number, along with the product's defect information on a screen. This allows for easy traceability of the defect factor. Depending on the product being manufactured (casting), the detection process can be performed on a variety of molds within the specified time period, and a variety of detection times, i.e., a variety of administrative numbers, can fall within the specified time period. In such a case, the display control 46 of the management device 40 assigns an administrative number corresponding to the product identified as defective, based on the detection results of a variety of sensor information, including the variety of administrative numbers. The sensor information includes detection results from sensor 16. For a mold where the detection result varies, a defective section may occur in the product manufactured with that mold. Similarly, for a mold, a detection result exceeding a threshold may result in a defect in a product manufactured with that mold. If the acquisition times for the multitude of administrative numbers fall within the specified time period, the display control 46 therefore selects the acquisition result exhibiting the deviation or the acquisition result exceeding the threshold as the specific acquisition result from among those acquired by sensor 16 within the specified time period. The display control 46 then selects the administrative number of this specific acquisition result from the multitude of administrative numbers as the administrative number corresponding to the product identified as defective. Subsequently, the sensor and control information, including the aforementioned administrative number, are displayed on a screen along with the product's defect information. The information displayed on the screen facilitates easy tracing of the defect factor. The measurement results can vary relative to the desired measurement results for the respective molds. The range of variation for the measurement result is defined for each measurement object, such as the moisture content of the molding sand. A measurement result with a deviation is defined as one that exceeds a specified range of variation. Furthermore, an acceptable range for the measurement result is defined. The acceptable range includes at least an upper limit or a lower limit for each measurement object, such as the moisture content of the molding sand. If the measurement result falls within the acceptable range, the status of the measurement result management element is set to "normal," and if the measurement result falls outside the acceptable range, the status of the measurement result management element is set to "abnormal."Even if the data collection result falls within the permissible range, the status of the administrative element can be set to "Caution" if the difference between the data collection result and the upper or lower limit is less than a predefined value. The threshold for the data collection result can be the upper or lower limit of the permissible range, or a value that differs from both the upper and lower limits. The display control 46 can use the detection result as a specific detection result if the status for the detection result is "abnormal" and can use the management number of the sensor information containing the specific detection result as a management number corresponding to the product identified as defective. Furthermore, the display control 46 can use the detection result as a specific detection result if the status for the detection result is "abnormal" or "Caution" and can use the management number of the sensor information containing the specific detection result as a management number corresponding to the product identified as defective. Although the preceding description applies to sensor information, the same is true for control information. That is, the control information includes a control result from the control operation performed on the mold. In the case of a mold with a deviation in the control result, or a mold where the control result exceeds a threshold, a defective section may occur in a product manufactured with that mold. Therefore, if the control times for the multitude of administrative numbers fall within the specified period, the display control 46 considers the control result with the deviation or the control result exceeding the threshold as a specific control result among the control results within the specified period.The display control unit 46 selects the administrative number of the specific control result from the multitude of administrative numbers as the administrative number corresponding to the product identified as faulty. Subsequently, the sensor and control information, including the aforementioned administrative number, are displayed on a screen along with the product's fault information. The information displayed on the screen allows for easy tracing of the fault factor. The control results can vary relative to the desired control results for the respective molds. The range of variation for the control result is defined for each measured object, such as the pouring temperature of the molten metal. A control result with a deviation is defined as one that exceeds a specified range of variation. Furthermore, an acceptable range for the control result is defined. The acceptable range includes at least one upper and one lower limit for each measured object, such as the pouring temperature of the molten metal. If the control result falls within the acceptable range, the status of the control result management element is set to normal; if the control result falls outside the acceptable range, the status of the control result management element is set to abnormal.The threshold for the tax result can be the upper limit or the lower limit of the permissible range, or a value that differs from both the upper and lower limits. Display control 46 can use the control result as a specific control result if the status for the control result is "abnormal" and can use the management number of the sensor information that includes the specific control result as a management number corresponding to the product identified as defective. Display control 46 can use the control result as a specific control result if the status for the control result is "abnormal" or "Caution" and can use the management number of the sensor information that includes the specific control result as a management number corresponding to the product identified as defective. Example of a display screen Next, an example of a display screen is described by the display controller 46 of the management device 40, with reference to Figs. 3, 4, 5, 6 to 7. Although Figs. 3, 4, 5, 6 to 7 illustrate a case in which English is used as the display language, the display language can be changed to any language. The display language can be changed as a setting. As illustrated in Fig. 3, the display control 46 of the management device 40 causes the display unit 48 to display a start screen G11. The start screen G11 includes an operating display area A111, an actual production quantity display area A112, a progress display area A113, a difference display area A114 and an error display area A115. The operating display area A111 shows the start time and operating duration. The actual production quantity display area A112 shows the planned quantity (production planning), the actual production quantity, and the quantity difference. The progress display area A113 shows the production quantity over time, with chart L11 of the planned quantity and chart L12 of the actual production quantity displayed as a function of the time of day. The difference display area A114 shows a short-term breakdown and the cycle duration. The detail buttons 1141 and 1142 for the short-term breakdown and the cycle duration, respectively, are displayed in the difference display area A114.The details buttons 1141 and 1142 each function as GUI elements that serve to transition from the start screen G11 to a screen displaying details. In the fault display area A115, the number of defective products and the product numbers 1151, 1152, and 1153 of the castings identified as defective are displayed. Product numbers 1151 to 1153 each function as GUI elements that serve to transition to a screen displaying defective product information for the corresponding casting. On the G11 start screen, the planned and actual production quantities can be confirmed. Furthermore, on the G11 start screen, it is possible to confirm the presence or absence of products identified as defective during inspection, along with their product numbers 1151 to 1153. Fig. 4 illustrates a fault information display screen G12 for displaying information about a defective product with product number "ABC1A". When product number 1151 is selected in Fig. 3, the display controller 46 in Fig. 1 causes the display unit 48 to display the fault information display screen G12 in Fig. 4. A back button 1200 is displayed in the upper left corner of the fault information display screen G12, as illustrated in Fig. 4. The back button 1200 acts as a GUI element for transitioning from the fault information display screen G12 to the home screen G11, as illustrated in Fig. 3. The display position of the back button 1200 can be changed to any desired position. The fault information display screen G12 includes a first display area A121 of fault information 52, a second display area A122 of sensor information 54 and a third display area A123 of control information 56. In the first display area A121, parts of image data 1211 and 1212 of the product included in the defect information 52 are displayed, along with a position marker 1213 indicating the defect location. At least one position marker 1213 can be specified. The display format of the position marker 1213 can be changed for each defect type. The display format can be a color, a shape, or the like. The sensor information 54, which corresponds to the product displayed in the first display area A121, is displayed in the second display area A122. The second display area A122 includes a number of display lines 1221 to 1225. The sensor information is displayed in each of these lines. For example, each of the display lines 1221 to 1225 shows a process (Process) in which the sensor information 54 is acquired, a control element (Control Point), and a status (Status) as elements of the sensor information 54. The number of display lines in the second display area A122 can be changed as desired. The elements displayed in each of the display lines 1221 to 1225 can also be changed as desired. The tax information 56, which corresponds to the product displayed in the first display area A121, is displayed in the third display area A123. The third display area A123 includes a number of display lines 1231 to 1237. The control information is displayed in each of these lines. For example, each of the display lines 1231 to 1237 shows a process (Process) in which the control information 56 is recorded, a management element (Control Point), and a status (Status) as elements of the control information 56. The number of display lines in the third display area A123 can be changed as needed. The elements displayed in each of the display lines 1231 to 1237 can also be changed as needed. In Fig. 4, the sensor information 54 displayed in the second display area A122 shows the sensor information (display element) “CB (Compactability)” and the status “Abnormality” (error) in display line 1221. In this way, the display control 46 initially displays the sensor information that has been determined to be abnormal for the multitude of display lines 1221 to 1225. The sensor information includes detection results from a multitude of sensors that correspond to the product number as the administrative number. Since the sensor information classified as abnormal is displayed first, the sensor information indicating an abnormality can be easily confirmed for the product classified as faulty. In Fig. 4, the control information displayed in the third display area A123 does not include the control information determined to be “abnormal”.Regarding tax information, display control 46 shows any tax information identified as "abnormal" first. This allows for easy confirmation of any tax information indicating an abnormality for the product classified as faulty. The display controller 46 changes the display format of the sensor information shown in each of the display lines 1221 to 1225 of the second display area A122 according to the status. For example, in display line 1222, the sensor information (display element) "Humidity" is "normal". The display controller 46 displays the "Humidity" in display line 1222 in a first display format. The display controller 46 displays "CB" in display line 1221 in a second display format, which differs from the first. The display format is changed by one or more of the following: character color, background color, character or background flashing, character thickness, character shape, and the like. For example, display line 1221 is shown with a red background color, and display line 1222 with a normal color (the system's background color). In Fig.4. The difference in background color in display lines 1221 to 1225 is indicated by dot hatching, and dots around the characters are omitted to improve the visibility of the characters displayed in display line 1221. When the status is "Caution," the display format can be the same as that of the "Normal" or "Abnormal" status, or it can be a different format. The display format is the same in the third display area, A123, for displaying control information. In Fig. 4, a details button 1201 is shown below the second display area A122. The details button 1201 functions as a GUI element used to transition to a display screen showing details of the sensor information. The fault information display screen G12 includes a fourth display area A124 for displaying alarm information. Display lines 1241 to 1243 of the fourth display area A124 show alarm information generated in the casting device 12, as illustrated in Fig. 1. The alarm information includes an event time, a device, a stage, and an alarm. The alarm stage can be expressed by a different display format (e.g., color). In this way, by displaying the alarm information together with the sensor and control information related to the product fault, it is possible to easily track a fault factor. Fig. 5 illustrates a detail display screen G13 for displaying details of the sensor information. The detail display screen G13 switches from the fault information display screen G12 when the details button 1201 of the fault information display screen G12, shown in Fig. 4, is selected. A back button 1300 is displayed in the upper left corner of the detail display screen G13, illustrated in Fig. 5. The back button 1300 acts as a GUI element for transitioning from the detail display screen G13 to the fault information display screen G12, illustrated in Fig. 4. The display position of the back button 1300 can be changed to any desired position. The detailed display screen G13 in Fig. 5 shows more types of sensor information than the second display area A122 in Fig. 4. Detailed display screen G13 includes a parameter display area A131 and a management element display area A132. Management element display area A132 shows a list of management elements. The sensor information details are displayed in management element display area A132. The sensor information includes a management element, a unit, a maximum and minimum value of a measurement result, an upper and lower limit of a permissible range, and a determination result. In management element display area A132, the display format of a measurement result that exceeds the permissible range can be changed.The sensor information, which is likely a factor in the error, can be checked more closely using the sensor information displayed in the administrative element display area A132. In parameter display area A131, the data collection results for the respective administrative elements in administrative element display area A132 are shown as bar charts. Parameter display area A131 displays a dashed line L131, indicating the upper limit of the permissible range, and a dashed line L132, indicating the lower limit of the permissible range. The data collection results for each administrative element are displayed with the length of the bar chart adjusted relative to the dashed lines L131 and L132, which define the permissible range. This makes it easy to see whether the individual administrative elements are within the permissible range. Fig. 6 illustrates a screen for analyzing a short-term breakdown G14. The short-term breakdown analysis screen G14 appears when the "Details" button 1141 of the home screen G11, illustrated in Fig. 3, is selected. A back button 1400 is displayed in the upper left corner of the short-term breakdown analysis screen G14. The back button 1400 acts as a GUI element for transitioning from the short-term breakdown analysis screen G14 to the home screen G11, illustrated in Fig. 3. The display position of the back button 1400 can be changed to any desired position. The screen for analyzing a short-term breakdown G14 includes a first display area A141, which displays an operating rate, a second display area A142, which displays a stop time in each process, and a third display area A143, which displays a warning list. The operating rate displayed in the first display area A141 is a ratio of the actual operating time to the intended production time and is represented by a pie chart. In the second display area A142, a process designation 1421 in the casting device 12, illustrated in Fig. 1, a stop time 1422 in each process designation 1421, and a total stop time 1423 in the casting device 12 are displayed. If the total stop time 1423 exceeds a defined value (threshold), the display format of the total stop time 1423 changes compared to the case where the total stop time does not exceed the defined value. The display format of the stop times 1422 and 1423 can be one or a combination of character color, background color, character or background flashing, character thickness, character shape, and the like. In one example, if the set value is exceeded, the stop times 1422 and 1423 are displayed with red characters. The display format of process designation 1421 can be changed according to the warning list shown in the third display area A143. The third display area A143 shows the time the warning occurred, the time it was registered, and the type of warning as a warning list. The display format of process designation 1421 can be one or a combination of character color, background color, character or background flashing, character thickness, character shape, and the like. For example, the background color of process designation 1421 is changed to "Green," "Yellow," and "Red" according to the warning list. This makes it easy to understand the alarm status in each process and the short-term breakdown for each process. Accordingly, information required for the operation of the equipment enclosed in the casting device 12, illustrated in Fig. 1, can be obtained. Fig. 7 illustrates a cycle duration display screen G15. The cycle duration display screen G15 appears when the details button 1142 of the start screen G11, illustrated in Fig. 3, is selected. A back button 1500 is displayed in the upper left corner of the cycle duration display screen G15. The back button 1500 functions as a GUI element for transitioning from the cycle duration display screen G15 to the start screen G11, illustrated in Fig. 3. The display position of the back button 1500 can be changed to any desired position. The cycle duration display screen G15 shows the cycle duration, with the horizontal axis representing the time of day and the vertical axis representing the duration. The cycle duration display screen G15 shows the cycle duration changing over time. The time of day on the horizontal axis corresponds to the control time in the control information. Accordingly, the cycle duration display screen G15 provides the necessary information for operating the devices contained in the casting device 12, illustrated in Fig. 1. Operational impacts of the first embodiment The operational effects of the first embodiment are described below. (1-1) The management device 40 manages a production line 12 (the casting device 12) for the product 20. The management device 40 includes the memory 28 for storing the sensor information received from the sensor 16 located in the production line 12, the memory 24 for storing the control information in the production line 12, and the memory 32 for storing the fault information, including image data of the product that has been identified as faulty with respect to a fault in the product 20. The management device 40 includes the display unit 48 and the display controller 46, which causes the display unit 48 to display a screen G12 containing fault information 52, sensor information 54 corresponding to the fault information 52, and control information 56 corresponding to the fault information 52. In this way, by displaying the sensor information and the control information together with the error information on one screen, error factors for product 20, which has been determined to be faulty, can be easily checked. (1-2) The sensor information includes the management number for each of the managed objects in the production line, the acquisition time for each of the managed objects in relation to the multitude of sensors, and the acquisition results obtained from the multitude of sensors in conjunction with one another. The control information includes the control time and the control status in the production line in conjunction with the management number. The fault information includes a registration time of the image data.The display control 46 uses at least one of the administrative number of the sensor information, which includes the acquisition time corresponding to the registration time, or the administrative number of the tax information, which includes the tax time corresponding to the registration time, as the administrative number that corresponds to the administrative object identified as faulty, and causes the display unit to display the sensor information and the tax information that includes the administrative number. In a case where the administrative number of the fault information does not directly correspond to the administrative number of the sensor information or the control information, the sensor information of the administrative number, including the acquisition time corresponding to the registration time, can be the acquisition result of sensor 16 for the product 20 identified as faulty. The control information of the administrative number, including the control time corresponding to the registration time, can be a result of a control operation performed on the product 20 identified as faulty. Therefore, by displaying the sensor information and the control information for the product 20 identified as faulty on the fault information display screen G12, it is possible to easily verify fault factors for the product 20 identified as faulty. (1-3) The display controller 46 uses the administrative number, where the sensor information was acquired within a specified time period relative to the registration time, as the administrative number corresponding to the administrative object identified as faulty. The sensor information, including the acquisition time within the specified time period relative to the registration time, includes the sensor 16's acquisition result for the product 20 identified as faulty. By displaying the sensor information that is most likely to be a fault factor for the product 20 identified as faulty, the fault factor for the product 20 identified as faulty can be easily verified. (1-4) The display control 46 uses the administrative number, where the tax date of the tax information lies within a specified period in relation to the registration date, as the administrative number corresponding to the administrative object identified as defective. The tax information, including the tax date within the specified period in relation to the registration date, includes the tax result for the product 20 identified as defective. By displaying the tax information that is more likely to be a factor contributing to the defect in product 20, the factor contributing to the defect in product 20 can be easily verified. (1-5) If the acquisition times for the multitude of administrative numbers are within the specified period, the display control 46 selects an acquisition result that shows a deviation or an acquisition result that exceeds a threshold as a specific acquisition result from among the acquisition results obtained from the multitude of sensors within the specified period, and selects the administrative number of the specific acquisition result from among the multitude of administrative numbers as the administrative number corresponding to the administrative object identified as faulty. A defect may occur in product 20, which is manufactured using the mold, where the detection result shows a deviation or exceeds the threshold. If the number of administrative numbers at the detection time within the specified period is greater than one, the defect factor for product 20 identified as defective can be easily verified by displaying the sensor information that is more likely to indicate a defect in product 20. (1-6) If the acquisition times for the multitude of administrative numbers are within the specified period, the display control 46 selects a control result that shows a deviation or a control result that exceeds a threshold as a specific control result from among the control results obtained from the multitude of sensors within the specified period, and selects an administrative number of the specific control result from among the multitude of administrative numbers as the administrative number corresponding to the administrative object identified as faulty. A defect may occur in product 20, which is manufactured using the mold, resulting in a deviation in the tax result or exceeding the threshold. If the number of administrative numbers at the time of recording is greater than one within the specified period, the defect factor for product 20, which is identified as defective, can be easily verified by displaying the tax information that is more likely to be related to a defect in product 20. (1-7) The display control 46 displays the acquisition results of the multitude of sensors in a first display form and causes the specific acquisition result to be displayed in a second display form that differs from the first display form. Since the specific measurement result is easily recognizable visually through such a display, it is possible to track the error factor more easily. (1-8) The display control 46 displays the multitude of control results in a first display form and causes the specific control result to be displayed in a second display form that differs from the first display form. Since the specific tax result is easily recognizable visually through such a display, it is possible to track the error factor more easily. (1-9) The production line forms a mold and pours molten metal into it to produce a casting. The product identified as defective is a casting removed from the mold. The sensor 16 detection result and the mold control result in the manufacturing process are managed via the mold number. However, in some cases, the mold number does not correspond to the casting removed from the mold. In this context, by using the detection time and the control time for the registration time of the defect information of the casting identified as defective by the inspection, the mold can be easily linked to the casting identified as defective.By displaying the fault information of the casting identified as faulty and the corresponding sensor and control information on a screen G12, the fault factor can be tracked more easily. Modification example of the first embodiment The first embodiment can be modified and implemented as follows. The first embodiment and the following modification example can be implemented in combination within a scope where no technical contradictions arise. In the following modification example, the same reference numerals are assigned to the same components as in the first embodiment, and their descriptions are omitted. The display control 46 can show the sensor data in the second display area A122 in descending order of the deviation in the measured value. The greater the deviation in the measured value, the greater, in some cases, its influence on the occurrence of a defect in product 20. By displaying the sensor data as discussed above, the defect factor for product 20 identified as defective can be easily tracked. Similarly, the display control 46 can show the control data in the third display area A123 in descending order of the deviation in the control data. By displaying the control data as discussed above, the defect factor for product 20 identified as defective can be easily tracked. Fig. 8 illustrates an error information display screen G12A of the modification example, which is to be displayed in the management device 40. The error information display screen G12A is displayed by selecting product number 1151, shown in Fig. 3, as is the error information display screen G12, illustrated in Fig. 4. When the back button 1200 is selected, the screen switches to the start screen G11, illustrated in Fig. 3. On the fault information display screen G12A, the display format of the second display area A122 differs from that of the fault information display screen G12, as illustrated in Fig. 4. On the fault information display screen G12A of the modified example, sensor information with the status "normal" is displayed below the sensor information shown in the second display area A122 in a so-called grayed-out print, where, for example, the entirety of each of the display lines 1222 to 1225 is displayed in gray, making the characters barely visually recognizable. With this display format, sensor information with the status "abnormal" can be more easily identified. For this reason, the sensor information displayed on the fault information display screen G12A makes it easier to track the fault factors. The management device 40 can display the fault information display screen G12A using a factor table T11 (see Fig. 9) in which the fault information and the factors are stored in conjunction with each other. In the factor table T11, fault classifications (fault types) and fault factors for the fault classifications are stored in conjunction with each other. The fault factors each include at least one element of the sensing elements or controls related to the sensor 16 that relate to the control information for the fault classification. The fault factors are each determined based on the type of fault that occurred in the past and a factor that caused the fault. In the example shown in Fig.9. For the error message "Scab", the "moisture content" of sensor 16 is assigned as factor 1; the "sand temperature" of sensor 16 is assigned as factor 2; and the "pouring temperature of the molten metal" in the controller is linked as factor 3. For the error message "Sand inclusion", the "CB value" of sensor 16 is linked as factor 1 and the "sand container internal pressure" in the controller is linked as factor 2. For the error message "Dent defect", the "compression pressure" of sensor 16 is linked as factor 1 and the "pouring duration" in the controller is linked as factor 2. The display control 46 of the management device 40 reads the factors associated with the fault information registered in the fault registration system 30, illustrated in Fig. 1, based on the factor table T11; then, only with respect to the "CB value," which represents the sensor information of the factor, i.e., with respect to display line 1221, illustrated in Fig. 8, display lines 1222 to 1225 are shown in a so-called grayed-out print, where the entirety of each of the display lines 1222 to 1225 is shown, for example, in gray, so that the characters are barely visible. This allows for easy verification of the status of the sensor information associated with the fault information, thus making it easier to track the fault factor. On the fault information display screen G12A, illustrated in Fig. 8, in the third display area A123, display lines 1231 and 1233 to 1237 can be grayed out based on the factor table T11 in Fig. 9, and the display format of display line 1232 must not be changed. This allows display line 1232 to be easily identified visually. This enables a simple check of the status of the control information linked as a factor for the fault information, thus making it easier to track the fault factor. As shown in Fig. 10, the management device 40 can display a fault information display screen G12B that includes only the sensor and control information related to the product's fault information. In one example, for the fault information of the product 20 identified as faulty, the management device 40 displays only the sensor and control information in a status identified as abnormal. For example, on the fault information display screen G12B, the sensor information is shown only for display line 1221 of the second display area A122, and the sensor information for display lines 1222 to 1225 is not shown. In the modification example illustrated in Fig. 10, since the control information is determined to be non-abnormal, the control information for display lines 1231 to 1237 is not shown.The sensor or control information classified as abnormal often becomes a fault factor for product 20. This makes it easy to trace the fault factor for product 20 identified as defective. As shown in Fig. 11, the management device 40 can only display the information stored as a factor in the factor table T11, shown in Fig. 9, on a fault information display screen G12C for the fault information of the product 20 identified as faulty. In the example illustrated in Fig. 9, with respect to the fault information "sand inclusion", the "CB value" of sensor 16 is linked as factor 1 and the "sand container internal pressure" in the controller as factor 2. The management device 40 displays only "CB" and "Fault" as sensor information in display line 1221 of the second display area A122 of the fault information display screen G12C. The management device 40 displays only "sand container internal pressure" and "Normal" as controller information in display line 1231 of the third display area A123 of the fault information display screen G12C.For this reason, the sensor and control information displayed on the fault information display screen G12C makes it easier to track the fault factor for the product identified as faulty 20. The management object to be registered in the defect registration system 30 is not limited to product 20 and can be any management object in the casting device 12. For example, defect information from a mold can be registered as a management object. In the case of a mold, it may happen that the worker discovers a defect when inserting a core. In this case, the worker inserting the core, or a person who receives a notification from the worker, registers the defect information in the defect registration system 30. In this way, by registering the defect information of the management object, which is not product 20, it is possible to track a defect factor in the manufacturing system 10. Second embodiment A manufacturing system 210 of a second embodiment is described below. In the manufacturing system 210 of the second embodiment, the same components as those of the manufacturing system 10 of the first embodiment are designated with the same reference numerals, and part of the description thereof can be omitted. Schematic configuration of the manufacturing system As illustrated in Fig. 12, the manufacturing system 210 includes a beam processing device 212, a control device 214, and a sensor 216. The beam processing device 212 constitutes a production line 212 for manufacturing a product 220 from a material 218. The beam processing device 212 includes one or more facilities for manufacturing the product 220. The blasting device 212 performs a surface treatment on a workpiece as a management object. The material 218 fed to the blasting device 212 is a workpiece before surface treatment and is a processing object for blasting. The management number of material 218 is, for example, a product number marked on the material 218. The product 220 produced by the blasting device 212 is a workpiece after surface treatment. The management number of product 220 is a product number marked on the product 220. That is, the management object in the manufacturing system 210 of the second embodiment includes the workpiece before surface treatment and the workpiece after surface treatment.Examples of surface treatment include blasting for descaling, deburring, roughening the surface, and the like of a workpiece such as a steel material, as well as shot peening to improve fatigue strength, and the like. The blasting device 212 processes the surface of the workpiece by spraying or splashing an abrasive material onto the surface of the workpiece. The control device 214 controls the equipment enclosed in the beam processing device 212. The control device 214 controls the equipment of the beam processing device 212 based on control information stored in memory 24 of the control system 22. The control device 214 stores control results in the equipment of the beam processing device 212 controlled by the control device 214 in memory 24 of the control system 22. The control information includes information about the equipment to be controlled, control parameters for the equipment, and the control results in the equipment. The control results include a detection result obtained from a sensor, such as a current sensor, corresponding to an object to be controlled. The control results include a control result of the device by the control device 214 and a control time for the device. The control result may include further information. The control device 214 stores the control information in memory 24 in conjunction with the control result and the control time. Memory 24 of the control system 22 is an example of the "second memory". Sensor 216 acquires sensor information on various types of control elements related to the manufacturing process in the beam processing device 212. Sensor 216 is provided in various types of equipment enclosed within the beam processing device 212 and acquires various types of information in the production line. For example, sensor 216 may include a temperature sensor. A sensor information acquisition system 26 includes memory 28. The sensor information acquisition system 26 stores the sensor information acquired by sensor 216 in memory 28. The sensor information includes measurement results of a control element by sensor 216 and a measurement time measured by sensor 216. The sensor information may include other information.The sensor information acquisition system 26 stores the management element by the sensor 216 and the acquisition time in combination with each other in memory 28 as sensor information. Memory 28 of the sensor information acquisition system 26 is an example of the "first memory". The defect registration system 30 is a system for recording information relating to product 220, which was identified as defective during shipping inspection, as defect information. The defect registration system 30 includes memory 32. Memory 32 stores defect information for the product 220 identified as defective. Whether product 220 is a non-defective or defective product is determined, for example, by a worker performing the inspection. The defect information includes, as information relating to product 220, image data of the product 220 identified as defective, location data indicating a defective section in product 220, and a registration time at which the image and location data are recorded. The defect information may include additional information.The fault registration system 30 stores the image data, the position data, and the registration time in memory 32, linked together. Memory 32 of the fault registration system 30 is an example of the "third memory". Manufacturing system 210 includes management device 40. Management device 40 manages the production line of product 220 in manufacturing system 210. The management device 40 displays various types of screens based on the information stored in the memories 24, 28, and 32 of the respective systems 22, 26, and 30. The management device 40 includes the display device 42. The display device 42 displays information relating to the manufacturing system 210. The display controller 46 controls the information acquisition, a display procedure, and the like for the display image of the display unit 48. The display controller 46 causes the display unit 48 to display several screens. The screens displayed by the display unit 48 include a screen relating to error information. The display control 46 causes the display unit 48 to display a screen that includes the fault information, the sensor information corresponding to the fault information, and the control information corresponding to the fault information. In this way, by displaying the sensor information and the control information together with the fault information on one screen, fault factors for the product 220 can be easily checked. Configuration example of a beam processing device As illustrated in Fig. 13, the jet processing device 212 includes a box 261, a spraying device 262, a conveying device 263, and a dust collection device 264. Fig. 13 illustrates an example of the configuration of the jet processing device 212, and the configuration of the jet processing device 212 can be modified as desired. Box 261 is a housing configured to hold material 218 as the treatment object. Inside box 261, a treatment chamber is provided for performing beam processing of the treatment object. The spraying device 262 performs abrasive blasting by spraying an abrasive onto the object. The spraying method of the spraying device 262 is, for example, an impeller type (centrifugal type). An air-type spraying method can also be used. The abrasive used can be, for example, steel shot or steel grit. The type of abrasive can be selected according to the specific blasting process. The spraying device 262 includes an abrasive container, a control cage, and an impeller. The abrasive is stored in the abrasive container. The control cage is used to adjust the opening area in the path from the abrasive container to the impeller. The control cage feeds a predetermined quantity of abrasive to the impeller. The impeller is rotated, for example, by a high-speed motor. The abrasive, applied to a blade of the impeller, is sprayed by the centrifugal force generated by the rotation. The spraying device 262 can include multiple impellers. In one example, the spraying device 262 includes five impellers. The conveying device 263 transports the material 218 as the treatment object into the treatment chamber of the box 261. In addition, the conveying device 263 transports the processed product 220 out of the treatment chamber of the box 261. The dust collection device 264 collects the dust generated during the blasting process. In the spraying device 262, the ambient temperature is detected by sensor 216. In the spraying device 262, the energy generated by the impact of the abrasive used for blasting is converted into heat. The heat generated by the spraying device 262 can reduce the service life of the motor that drives the impeller, the conveying device, and other components within the device. The spraying device 262 manages control information such as the current value of the motor driving the impeller (impeller current), the particle size of the abrasive, the conveying speed, and other parameters. As shown in Fig. 12, the display controller 46 of the management device 40 causes the display unit 48 to display different types of screens based on the different types of information stored in the memories 24, 28, and 32 of the systems 22, 26, and 30, respectively. A screen displayed by the display unit 48 includes fault information 252, sensor information 254, and control information 256. The display controller 46 of the management device 40 causes the display unit 48 to display a screen that includes the fault information 252, the sensor information 254 corresponding to the fault information 252, and the control information 256 corresponding to the fault information 252. Example of a display screen Next, an example of a display screen is described by the display control 46 of the management device 40, with reference to Fig. 14, Fig. 15 to Fig. 16. Although Figures 14, 15 to 16 illustrate a case where Japanese is used as the display language, the display language can be changed to any language. The display language can be changed as a setting. As shown in Fig. 14, the display control 46 of the management device 40 causes the display unit 48 to display a start screen G21. The start screen G21 includes an operating display area A211, an actual production quantity display area A212, a progress display area A213, a difference display area A214 and an error display area A215. The operating display area A211 shows the operating status, operating duration, integrated spray duration, test result before start of operation and jet supply quantity of the jet processing device 212. The display area for the actual production quantity A212 shows the planned quantity, the actual production quantity and the difference. The progress indicator area A213 represents a temporal progression (accumulation) of the production quantity, displaying a graph of the planned quantity and a graph of the actual production quantity as a function of the time of day. The current operating status, the number of abnormalities, and the replacement prediction are displayed in the differential display area A214. In this case, the replacement prediction is displayed when the replacement period of a consumable component in the beam processing device 212 approaches, and it is displayed, for example, when the replacement period of an impeller approaches. These function as GUI elements that are used to transition to an operating status display screen G23, as shown in Fig. 16. In the fault display area A215, the product numbers 2151 to 2154 of the products 220 identified as faulty, as well as the faulty percentage, are displayed. Product numbers 2151 to 2154 each function as a GUI element that links to a screen displaying faulty product information for the corresponding product 220. On the G21 start screen, the planned and actual production quantities can be confirmed. Furthermore, on the G21 start screen, it is possible to confirm the presence or absence of products identified as defective during inspection, along with their product numbers 2151 to 2154. Fig. 15 illustrates a fault information display screen G22 for displaying information about a defective product with product number "AA01". When product number 2151 is selected in Fig. 14, the display controller 46 in Fig. 12 causes the display unit 48 to display the fault information display screen G22 in Fig. 15. A back button 2200 is displayed in the upper left corner of the fault information display screen G22, as shown in Fig. 15. The back button 2200 acts as a GUI element for transitioning from the fault information display screen G22 to the home screen G21, illustrated in Fig. 14. The display position of the back button 2200 can be changed to any desired position. The fault information display screen G22 includes a first display area A221 for the fault information 252, a second display area A222 for the sensor information 254 and a third display area A223 for the control information 256. In the first display area A221, parts of image data 2211 and 2212 of the product included in the fault information 252 are displayed, along with a position marker 2213 indicating the fault location. At least one position marker 2213 can be specified. The display format of the position marker 2213 can be changed for each fault type. The display format can be a color, a shape, or the like. The sensor information 254, corresponding to the product displayed in the first display area A221, is shown in the second display area A222. This sensor information includes the status of data acquisition results from the numerous sensors, which correspond to the product number as the administrative number. Because the sensor information classified as abnormal is displayed first, the sensor information indicating an abnormality can be easily confirmed for the product classified as faulty. The tax information 256, corresponding to the product displayed in the first display area A221, is shown in the third display area A223. Similarly, if the tax information includes tax information identified as "abnormal," display control 46 shows this information first. This allows for easy confirmation of the tax information indicating an abnormality for the product classified as faulty. In the second display area A222, the display format changes according to the status, similar to the second display area A122 of the first embodiment, illustrated in Fig. 4. In the second display area A222, sensor information with a "normal" status can be displayed in a way that is visually difficult to recognize, for example, by displaying the sensor information in gray characters. Only sensor information with an "abnormal" status may be displayed in the second display area A222. In the third display area A223, the display format changes according to the status, similar to the second display area A122 of the first embodiment, illustrated in Fig. 4. In the third display area A223, control information with a "normal" status can be displayed in a way that is visually difficult to recognize, for example, by displaying the control information in gray characters. Only control information with an "abnormal" status may be displayed in the third display area A223. The fault information display screen G22 includes a fourth display area A224 for showing alarm information. Display lines 2241 to 2243 of the fourth display area A224 show alarm information generated in the beam processing device 212, as illustrated in Fig. 12. The alarm information includes an event time, a stage, and an alarm type. The alarm stage can be expressed by a different display format (e.g., color). In this way, by displaying the alarm information together with the sensor information and the control information related to the product fault, it is possible to easily track a fault factor. Fig. 16 illustrates an operating status display screen G23. The operating status display screen G23 appears when the differential display area A214, shown in Fig. 14, is selected. A back button 2300 is displayed in the upper left corner of the operating status display screen G23. The back button 2300 functions as a GUI element for transitioning from the operating status display screen G23 to the start screen G21, illustrated in Fig. 14. The display position of the back button 2300 can be changed to any desired position. The operating status display screen G23 includes a first display area A231 for showing the operating status and the like. The operating status, operating time, integrated spray duration, number of processing cycles, and jet feed rate of the jet processing device 212 are displayed in the first display area A231. The operating status display screen G23 includes a second display area A232 for showing sensor and control information, and a third display area A233 for showing a graph depicting the time course of sensor and control information. The sensor and control information displayed in the second display area A232 indicates the values received at the current time. The current and past operating status can be checked in the operating status display screen G23. The operating status display screen G23 includes a fourth display area A234 for showing alarm information. Display lines 2341 to 2343 of the fourth display area A234 show alarm information generated in the beam processing device 212, as illustrated in Fig. 12. The alarm information includes an event time, a recovery time, a level, and an alarm type. The alarm level can be expressed by a different display format (e.g., color). In this way, by displaying the alarm information together with the sensor and control information related to the product defect, it is possible to easily track a fault factor. Operational impacts of the second embodiment The operational effects of the second embodiment are described below. (2-1) As regards the product 220, which is processed by the beam processing device 212, which forms the production line of the manufacturing system 210 of the second embodiment, it is possible to easily track defect factors, just as with the manufacturing system 10 of the first embodiment. Modification example The embodiment described above can be modified and implemented as follows. The embodiment described above and the following modification example can be implemented in combination within a scope where no technical contradictions arise. In the following modification example, the same reference numerals are assigned to the same components as in the embodiment described above, and their descriptions are omitted. The factors for the error information in the factor table T11, illustrated in Fig. 9, can, for example, be stored by a worker. The factor table T11 can be created using machine learning. As illustrated in Fig. 17, a processor P11 creates the factor table T11 using a trained model created by machine learning, taking into account the fault information 52, the sensor information 54, and the control information 56. One or more processors P11 can be provided. In this way, the factor table T11 is created by machine learning on one or more processors P11. This allows for easy creation of the factor table T11. Furthermore, because machine learning is used, it is easy to add configuration contents and factors to the factor table T11, and so on. In the defect registration system 30, the determination for each of the products 20 and 220 can be carried out, for example, by a computer performing image processing. The computer checks each of the manufactured products 20 and 220 using a trained model created by machine learning using image data of defect-free products and image data of defective products from the past. The computer then stores the test result as defect information in memory 32. The embodiments disclosed herein are in every respect merely examples, and the present invention is not limited to these examples. That is to say, the scope of protection of the present invention is defined by the claims and is intended to include all modifications within the meaning and scope of protection that correspond to the claims.
