     DESCRIPTION OF EMBODIMENTS 
     Embodiment 1 
     The following description will discuss Embodiment 1 of the present invention in detail.  FIG. 1  is a block diagram illustrating a configuration of a sales device  1  in accordance with Embodiment 1. Embodiment 1 will be described with reference to the sales device  1  for selling an information processing device (relay device) with use of the Internet. 
     As illustrated in  FIG. 1 , the sales device  1  includes at least one processor  11 , a memory  12 , a communication section  13 , and an input-output interface (I/O interface)  14 . The processor  11  centrally controls the sales device  1 . The memory  12  includes a primary memory and a secondary memory. The primary memory is, for example, a semiconductor random access memory (RAM). The secondary memory is, for example, a flash memory, a hard disk drive (HDD), a solid state drive (SSD), an optical disk drive (ODD), a floppy disk drive (FDD), or a combination of any of those listed above. 
     In Embodiment 1, the memory of the sales device  1  is realized by two memories (the primary memory and the secondary memory); however, this does not imply any limitation. That is, the memory of the sales device  1  may be realized by a single memory. In this case, for example, a certain storage area of the memory may be used as the primary memory and another storage area of the memory may be used as the secondary memory. 
     The processor  11  reads a sales program P 1 , which is stored in the secondary memory, from the secondary memory and loads the sales program P 1  into the primary memory. Then, the processor  11  carries out steps included in a sales method M 1  in accordance with instructions contained in the sales program P 1  thus loaded. That the sales program P 1  is stored in the secondary memory means that a source code or an executable file obtained by compiling the source code is stored in the secondary memory. 
     Further, the processor  11  reads a setting program P 2 , which is stored in the secondary memory, from the secondary memory and loads the setting program P 2  into the primary memory. Then, the processor  11  carries out steps included in a setting method M 2  in accordance with instructions contained in the setting program P 2  thus loaded. 
     A device that can be used as the processor  11  is, for example, a central processing unit (CPU), a graphic processing unit (GPU), a digital signal processor (DSP), a micro processing unit (MPU), a floating point number processing unit (FPU), a physics processing unit (PPU), a microcontroller, or a combination of any of those listed above. 
     The communication section  13  of the sales device  1  is configured to have, connected thereto, a user terminal (computer) T 1 , . . . Tn (hereinafter referred to as a “user terminal T”) in a wired manner or wirelessly over a network N. Examples of the communication section  13  include Ethernet (registered trademark) and Wi-Fi (registered trademark) interfaces, and the like. Examples of the network that can be employed include personal area network (PAN), local area network (LAN), campus area network (CAN), metropolitan area network (MAN), wide area network (WAN), global area network (GAN), and an internetwork including any of such networks. The internetwork may be an intranet, an extranet, or the Internet illustrated in  FIG. 1 . 
     Examples of the input-output interface  14  include universal serial bus (USB), advanced technology attachment (ATA), small computer system interface (SCSI), and peripheral component interconnect (PCI) interfaces, and the like. The input device connected to the input-output interface  14  can be, for example, a keyboard, a mouse, a touchpad, a microphone, or a combination of any of those listed above. The output device connected to the input-output interface  14  can be, for example, a display, a projector, a printer, a speaker, a headphone, or a combination of any of those listed above. 
     Note that, although Embodiment 1 employs a configuration in which a single processor  11  is used to carry out the sales method M 1 , the present invention is not limited to such. That is, a configuration in which a plurality of processors are used to carry out the sales method M 1  may be employed. In this case, a plurality of processors which work together to carry out the sales method M 1  may be provided in a single computer and configured to be communicable with each other through a bus or may be provided in a respective plurality of computers and configured to be communicable with each other over a network. For example, the following configuration can be employed: a processor contained in a computer constituting a cloud server and a processor contained in a computer owned by a user of the cloud server work together to carry out the sales method M 1 . 
     The sales device  1  is a sales device for selling the information processing device (relay device)  3  that collects data from at least one of at least one sensor and at least one piece of accessory equipment and provides the data to a controller included in a piece of main equipment. Hereinafter, “at least one sensor and/or at least one piece of accessory equipment” will be also referred to as “a sensor and/or a piece of accessory equipment”. The information processing device  3  has a “linking” function, a “collecting” function, and an “informing” function. Hereinafter, the information processing device  3  will be also referred to as “relay device  3 ”. The relay device  3  is an aspect of the “information processing device” recited in the claims. 
     A person in charge of the company, who is a user (purchaser), can purchase a piece of accessory equipment and/or a sensor attachable to an existing piece of main equipment, via the Internet N together with the relay device  3 . That is, the user can purchase the relay device and the sensor and/or the piece of accessory equipment by inputting predetermined information into a display screen (also referred to as an “operation screen”), which is caused by the sales device  1  to be displayed on a web screen of the user terminal T on the Internet N. Alternatively, the user may purchase a new piece of main equipment and also purchase, via the Internet N, a sensor and/or a piece of accessory equipment attachable to the piece of main equipment. 
     Specifically, the processor  11  of the sales device  1  carries out a first process of receiving a user operation for specifying a type of at least one of a sensor and a piece of accessory equipment. The processor  11  also carries out a second process of receiving a user operation for specifying a memory area which is included in the controller and in which data collected from the at least one of the sensor and the piece of accessory equipment specified in the first process is to be recorded. The first process and the second process are carried out through the web screen on the user terminal T. A manner in which a screen for the first process or the second process is displayed is not limited. In other words, the processor  11  of the sales device  1  carries out the first process of receiving, on the user terminal T, a user operation for specifying a type of at least one of a sensor and a piece of accessory equipment. The processor  11  also carries out a second process of receiving, on the user terminal T, a user operation for specifying a memory area which is included in the controller and in which data collected from the at least one of the sensor and the piece of accessory equipment specified in the first process is to be recorded. The processor  11  of the sales device  1  may be on the cloud. Note that a specific example of the display screen, which the processor  11  causes to be displayed on the user terminal T in order to receive a user operation, will be described later. 
     With the configuration above of the sales device  1 , it is possible to provide a sales device for selling a relay device for facilitating connection between a piece of accessory equipment or the like to be purchased and an existing main piece of equipment. 
     The following description will discuss a function of the relay device  3  with reference to  FIG. 2 .  FIG. 2  is a diagram schematically illustrating a relationship between (i) a relay device  3  in accordance with Embodiment 1 and (ii) a piece of main equipment  2  and at least one of at least one sensor  4  and at least one piece of accessory equipment  5 . 
     The piece of main equipment  2  is a piece of equipment already in use by the user company or a piece of equipment to be newly purchased. The sensor  4  and/or the piece of accessory equipment  5  are newly purchased by the user company together with the relay device  3 , for use with the piece of main equipment  2 . That is, the piece of main equipment  2  and the sensor  4  and/or the piece of accessory equipment  5  are basically independently functioning and operated pieces of equipment. The relay device  3  relays information communication between the sensor  4  and/or the piece of accessory equipment  5  and the main equipment  2 . Specifically, the relay device  3  has a function of collecting (obtaining) data from the sensor  4  and/or the piece of accessory equipment  5  and causing the collected data to be written into a memory  22  of a controller  21  of the main piece of equipment  2 . The monitor screen  6  displays, in real time, the data collected by the relay device  3 . The monitor screen  6  may be a dashboard (a display panel) or the like included in the relay device  3 , or may be a display device connected to the relay device  3 . 
     For example, the piece of main equipment  2  is a manufacturing device and is controlled by the controller  21 . The sensor  4  is a first sensor (e.g., a temperature sensor)  4 A, a second sensor (e.g., an open/close sensor)  4 B, . . . and so on. The piece of accessory equipment  5  is a piece of first accessory equipment (e.g., a conveyor)  5 A, a piece of second accessory equipment (e.g., a dust collector)  5 B, . . . and so on. Note that the term “sensor  4 ” is used to refer to these sensors collectively regardless of the types of the sensors, and the term “piece of accessory equipment  5 ” is used to refer to these pieces of accessory equipment collectively regardless of the types of the pieces of accessory equipment. The relay device  3  receives sensor data from the sensor  4  and causes the sensor data to be written into the memory  22  of the controller  21 . The relay device  3  receives operation data from the piece of accessory equipment  5  and causes the operation data to be written into the memory  22  of the controller  21 . The operation data is, for example, an operation start time, an operation stop time, various output values of the piece of equipment, information of detected abnormality, and the like. The sensor data and the operation data may be hereinafter collectively referred to as “data”. 
     The relay device  3  causes the data collected from the sensor  4  and/or the piece of accessory equipment  5  to be written into a predetermined memory area (memory address) in the memory  22  of the controller  21 . The user who makes a purchase can specify which data to write into which memory area. The controller  21  controls the piece of main equipment  2  as needed on the basis of the data written into the memory  22 . The controller  21  can control not only the piece of main equipment  2  but also the piece of accessory equipment  5  on the basis of the data written into the memory  22 . 
     In a case where the relay device  3  collects data from the sensor  4  and/or the piece of accessory equipment  5 , the data may be collected in a wired manner, or may be collected at least partially wirelessly. Wireless communication thus used can be, for example, Ethernet (registered trademark), Wi-Fi (registered trademark), or the like. Further, the relay device  3  may be configured to transmit and receive data with use of a network such as the Internet. Similarly, in a case where the relay device  3  causes data to be written into the memory  22 , the data may be written in a wired manner, or may be written wirelessly. 
     The relay device  3  converts data collected from the sensor  4  and/or the piece of accessory equipment  5 , which is manufactured by a different manufacturer, into a unified data format readable by the controller  21 . Further, the relay device  3  structures the data, the data format of which has been converted, by arranging the data by time for each sensor  4  and/or each piece of accessory equipment  5 . Then, the relay device  3  causes the data thus structured to be written into a specified memory area in the memory  22 . Thus, the user simply designates which memory area in the memory  22  data is to be recorded by the relay device  3 , and this allows the controller  21  to use data recorded in a specified memory area to carry out control as needed. 
     For example, retrofitting a new sensor and/or a new piece of accessory equipment to an existing piece of main equipment incurs a great deal of labor and expense in the work of connecting the piece of main equipment and the sensor and/or the piece of accessory equipment because a data format and a data communication method differ between the piece of main equipment and the sensor and/or the piece of accessory equipment. In a case where a new set of a piece of main equipment and a sensor and/or a piece of accessory equipment desired by the user is purchased by the user, the user needs to construct the set by themselves because there is no off-the-shelf set of such pieces of equipment and a sensor. As such, also in this case, a great deal of labor and expense are incurred in the work of connecting the piece of main equipment and the sensor and/or the piece of accessory equipment. By purchasing the above relay device  3  together, however, the user can easily connect, to the piece of main equipment  2 , the sensor  4  and/or the piece of accessory equipment  5  to be retrofitted. Then, the user can centrally manage data from the sensor and/or the piece of accessory equipment and use the data for process control, safety control, and the like. Further, data of the sensor and/or the piece of accessory equipment can be used to cause the piece of main equipment  2  to control the piece of accessory equipment  5 . In this case, the piece of main equipment  2  may control the piece of accessory equipment  5  via the relay device  3 , or may control the piece of accessory equipment  5  by direct information communication with the piece of accessory equipment  5 . Also in a case where a piece of main equipment  2  and a sensor  4  and/or a piece of accessory equipment  5  are newly purchased together, a similar advantage can be obtained by purchasing the relay device  3  together. 
     Returning to  FIG. 1 , the following description will discuss a function of the processor  11 . The processor  11  may carry out a third process of setting the relay device  3  so that the relay device  3  causes data collected from the sensor  4  and/or the piece of accessory equipment  5 , whose type has been specified in the first process, to be written into the memory area, which has been specified in the second process, in the memory  22  of the controller  21 . The third process is, for example, a process in which the processor  11  (i) displays an operation screen for causing the user to input a beginning address of the memory area in which the data is to be written into, (ii) obtains information thus inputted, and (iii) sets the relay device  3  on the basis of the information. Through the third process, the sales device  1  can obtain information of the memory area in which the data collected from the sensor  4  and/or the piece of accessory equipment  5  is to be recorded. Further, the user can specify, when making a purchase, a memory area in which data is to be recorded in the memory  22 . Thus, setting is made so that data transmitted from the sensor  4  and/or the piece of accessory equipment  5  which have/has been newly purchased is recorded in a predetermined area of the memory  22  by the relay device  3 . As a result, the user need not carry out setting for causing the data to be recorded in the memory  22 . Note that a manner in which the operation screen used in the third processing is displayed is optional. Specific examples thereof, including a manner in which an operation screen used in each process described below is displayed, will be described later. 
     Note that, as the third process of setting the relay device  3 , the processor  11  may carry out a process of transmitting information for setting the relay device  3  to the relay device  3  via the network, or may carry out a process of causing the information to be stored in the memory  12 . In the latter case, the information for setting the relay device  3  is inputted to the relay device  3  via a portable storage medium or the like. Thus, the relay device  3  is set. 
     The processor  11  can also carry out at least one of: a fourth process of receiving a user operation for specifying a manufacturer of the sensor  4  and/or the piece of accessory equipment  5 ; and a fifth process of receiving a user operation for specifying a manufacturer of the controller  21 . The fourth process is, for example, a process of (i) displaying an operation screen for causing the user to input or select a name of a manufacturer of the sensor  4  and/or the piece of accessory equipment  5  and (ii) obtaining information inputted by the user. The fifth process is, for example, a process of (i) displaying an operation screen for causing the user to input or select a name of a manufacturer of the controller  21  and (ii) obtaining information inputted or selected by the user. Through the fourth process, the sales device  1  can obtain information of the sensor  4  and/or the piece of accessory equipment  5  purchased by the user. Through the fifth process, the sales device  1  can obtain information of the controller  21  of the piece of main equipment  2  owned by the user. Further, the user can easily input predetermined information. 
     The processor  11  may also carry out a sixth process of generating a memory map which indicates a memory area of the memory  22  of the controller  21  and data to be recorded in the memory area. Through the sixth process, the user can check (i) which memory area is to have data recorded and (ii) from which sensor  4  and/or which piece of accessory equipment  5  the data is from. 
     The processor  11  may also carry out a seventh process of receiving a user operation for selecting a type of product from a plurality of candidates. The seventh process is, for example, a process in which, when a name of a manufacturer is specified, types of products that are manufactured by the manufacturer are displayed in a drop-down menu on an operation screen, and information selected by the user is obtained. Through the seventh process, the user can easily specify the sensor  4  and/or the piece of accessory equipment  5  on the operation screen. 
     The processor  11  may carry out an eighth process of receiving a user operation for setting the monitor screen  6  of the relay device  3  so that the monitor screen  6  displays, in a predetermined layout, the data collected by the relay device  3 . Along with the eighth process, the processor  11  may receive a user operation which the user carries out to designate in what manner the data collected by the relay device  3  is to be displayed. 
     The eighth process is, for example, a process of (i) displaying, on an operation screen, a display position representing at which position the data is to be displayed on the monitor screen  6 , (ii) causing the user to select the display position, and (iii) obtaining pieces of information thus designated by the user. At this time, the processor  11  may (i) cause a plurality of manners, in each of which data is to be displayed, to be displayed on the operation screen for the respective types of data and (ii) cause the user to select a manner from among the plurality of manners. As described above, the monitor screen  6  may be a display panel incorporated in the relay device  3 , or may be a display device provided separately from the relay device  3 . Through the eighth process, the user can make customization such that desired data is displayed in a desired position on the monitor screen and, optionally, in a desired manner. 
     The eighth process may be a process of receiving a user operation for specifying an area which is displayed on the operation screen and in which the data is to be displayed on the monitor screen  6 . In addition to this process, the user may be caused to specify a display pattern which indicates a manner in which the data is to be displayed. Specifically, the eighth process may be a process of (i) displaying, on the operation screen, a display pattern indicative of a manner in which the data is to be displayed and an area in which the data is to be displayed on the monitor screen  6 , (ii) causing the user to specify the display pattern by dragging and dropping the display pattern, and (iii) obtaining information thus specified. 
     According to the sales device  1  having the above-described configuration, the processor  11  of the sales device  1  carries out the first process of receiving a user operation for specifying a type of at least one of the sensor  4  and the piece of accessory equipment  5 . The processor  11  also carries out the second process of receiving a user operation for specifying a memory area which is included in the memory  22  of the controller  21  and in which data collected from the at least one of the sensor  4  and the piece of accessory equipment  5  specified in the first process is to be recorded. Thus, on the basis of information obtained by the first process and the second process, the relay device  3  can be set so as to cause data of the sensor  4  and/or the piece of accessory equipment  5  to be recorded in the memory  22  of the controller  21 . Thus, it is possible to provide a sales device for selling an information processing device (relay device) for facilitating connection between a piece of accessory equipment or the like to be purchased and an existing main piece of equipment. 
     (Sales Method) 
     The following description will discuss a sales method carried out with use of the sales device  1  in accordance with Embodiment 1.  FIG. 3  is a flowchart illustrating a flow of the sales method M 1 . The sales method M 1  includes the following steps. As indicated in Step S 11 , the processor  11  carries out the first process of receiving a user operation for specifying a type of at least one of the sensor  4  and the piece of accessory equipment  5 . Subsequently, as indicated in Step S 12 , the processor  11  carries out the second process of receiving a user operation for specifying a memory area which is included in the controller  21  and in which data collected from the at least one of the sensor  4  and the piece of accessory equipment  5  specified in the first process is to be recorded. As described above, a manner in which a screen for each process is displayed is not limited. 
     As indicated in Step S 13 , the processor  11  may carry out the third process of setting the relay device  3  so that the relay device  3  causes data collected from the at least one of the sensor  4  and the piece of accessory equipment  5  specified in the first process to be written into the memory area, which has been specified, in the memory  22 . 
     Further, in the sales method carried out by the processor  11 , the processor  11  may carry out any of the fourth to ninth processes described above. 
     According to the sales method M 1  having the above configuration, the processor  11  of the sales device  1  carries out the first process of receiving a user operation for specifying a type of at least one of the sensor  4  and the piece of accessory equipment  5  and the second process of receiving a user operation for specifying a memory area which is included in the memory  22  of the controller  21  and in which data collected from the at least one of the sensor  4  and the piece of accessory equipment  5  specified in the first process is to be recorded. Thus, it is possible to provide a sales method for selling an information processing device (relay device) for facilitating connection between a piece of accessory equipment or the like to be purchased and an existing main piece of equipment. 
     (Process of Receiving Order) 
     The following description will discuss, with reference to drawings, a process carried out by the processor  11  of the sales device  1  of receiving an order placed by the user.  FIG. 4  is an example of an operation screen (graphical user interface (GUI)) which is displayed on the user terminal T when a user accesses a website that sells the relay device  3 . The website that sells the relay device  3  is a website set up on the network by a company that manages the sales device  1 . The company managing the sales device  1  may be a company that manufactures the relay device  3 , or a sales company that has been commissioned by the company manufacturing the relay device  3  to sell the relay device  3 . 
     As illustrated in  FIG. 4 , a display screen  400  is an operation screen for receiving a user operation of inputting client information. Specifically, the display screen  400  displays a text box  401  for inputting a name of a person in charge, a text box  402  for inputting an email address, a text box  403  for re-inputting the email address for confirmation, a text box  404  for inputting a telephone number, and a text box  405  for inputting a company name. When the user clicks on a button  406  after inputting these pieces of information into the respective text boxes, the information thus inputted is transmitted to the sales device  1 , and a transition to a display screen  500  as illustrated in  FIG. 5  occurs. 
     The display screen  500  is an example of an operation screen for receiving the user&#39;s input operation for selecting whether the user is to source the sensor  4  by themselves or collectively purchase the sensor  4  from the company (indicated as “ZZ Co., Ltd.” in  FIG. 5 ) manufacturing the relay device  3 . The user clicks on a button  501  in a case of sourcing the sensor  4  by themselves, and clicks on a button  502  in a case of collectively purchasing the relay device  4  from the company manufacturing the relay device  3 . A condition (e.g., that an extra charge will be incurred) applied to the case where the user collectively purchases the sensor  4  may be displayed on the screen. The button  501  and the button  502  are radio buttons only one of which is selectable. When the user has finished inputting and clicks on a button  503 , information thus inputted is transmitted to the sales device  1 , and a transition to a display screen  600  as illustrated in  FIG. 6  occurs. 
     The display screen  600  is an example of an operation screen for receiving a user operation of inputting information of the controller  21  of the piece of main equipment  2  currently in use by the user. The controller information is, for example, a manufacturer, a type, and a model number of the controller  21 . The type is, for example, a programmable logic controller (PLC), a numerical control (NC), a personal computer (PC), or the like. The model number is a model number of the controller  21 . 
     The above pieces of controller information can be selected from drop-down menus  601 ,  602 , and  603 , respectively. For example, when the user clicks on a drop-down button (an inverted triangular button) of the drop-down menu  601 , a list of manufacturer names is shown, and the user can select one of the manufacture names. The drop-down menu  602  is configured to show, when the user selects one manufacturer from the drop-down menu  601 , a list of types of controllers that are manufactured by the manufacturer. The drop-down menu  603  is configured to show, when the user selects a type, a list of model numbers of the type. The above process in which the processor  11  uses the drop-down menu  601  to receive a user operation for specifying a manufacturer of the controller  21  is an example of the fifth process described above. When the user has made all the selections and clicks on a button  604 , information thus inputted is transmitted to the sales device  1 , and a transition to a display screen  700  as illustrated in  FIG. 7  occurs. 
     The display screen  700  is an example of an operation screen for receiving a user operation for designating a sensor to be connected to the network. On the display screen  700 , the user specifies (i) a secondary sensor unit to be connected (a sensor to be newly added) and (ii) a beginning address in the memory  22  of the controller  21  in a case where information transmitted from each sensor is to be recorded in the memory  22 . The secondary sensor unit can be specified by selecting a manufacturer displayed in a drop-down menu  701 , a type displayed in a drop-down menu  702 , and a model number displayed in a drop-down menu  703 . In a case where there are a plurality of secondary sensor units, an add button  704  can be clicked on to select the plurality of secondary sensor units in a similar fashion. The above process in which the processor  11  uses the drop-down menu  702  to receive a user operation for specifying a type of the secondary sensor unit is examples of the first process and the seventh process described above. The above process in which the processor uses the drop-down menu  701  to receive a user operation for specifying a manufacturer of the secondary sensor unit is an example of the fourth process described above. 
     When the user designates a manufacturer from the drop-down menu  701 , the drop-down menu  702  shows a list of types of controllers that are manufactured by the manufacturer. When the user designates a type of sensor, the drop-down menu  703  shows a list of model numbers of the type. Examples of a type of sensor include, but are not limited to, a CO 2  sensor, a temperature sensor, and an open/close sensor. The model number is a model number of each sensor. In accordance with the number of sensors thus designated, a display area  705  displays the number of designated sensors by a message “NUMBER OF DEVICES USED IN SENSOR INFORMATION IS XX”. 
     Subsequently, in a case where the controller  21  has address numbers of the memory, the user designates a beginning address for sensor information. The beginning address for sensor information is information that indicates from which area in the memory  22  of the controller  21  sensor information is to be recorded in a case where the sensor information is recorded in the memory  22 . This information is necessary when preparing a memory map (described later). For example, in a case where the controller  21  is a PLC, the memory area is defined by an alphabetic letter and numbers. In this case, the user selects the first alphabetic letter from a drop-down menu  706  and input numbers in a text box  707 .  FIG. 7  illustrates a case in which the beginning address for sensor information in the memory  22  is D8000. That is, the user clicks on a drop-down button (an inverted triangular button) of the drop-down menu  706  to select an alphabetic letter “D”. The user then inputs, in the text box  707 , a number “8000” of the address in the memory  22 . The above process in which the processor  11  uses the display screen  700  to receive a user operation for specifying a memory area in the memory  22 , in which memory area data collected by the processor  11  from the secondary sensor unit is to be recorded, is an example of the second process described above. When the user has finished inputting and clicks on a button  708 , information thus inputted is transmitted to the sales device  1 , and a transition to a display screen  800  as illustrated in  FIG. 8  occurs. In a case where the controller  21  does not have address numbers of the memory, it is not necessary to carry out this input process. 
     The display screen  800  is an example of an operation screen for receiving a user operation of inputting (i) whether or not there is a piece of accessory equipment in use by the user and (ii) if yes, information of the piece of accessory equipment. First, the user selects whether or not there is a piece of accessory equipment. In a case where there is a piece of accessory equipment, the user clicks on a button  801 . If there is not a piece of accessory equipment, the user clicks on a button  802 . Clicking on the button  801  causes items of accessory equipment information to be displayed in a selectable manner. That is, clicking on the button  801  causes drop-down menu buttons  803 ,  804 , and  805  and an add button  806 , which are not selectable and are displayed in a light color in  FIG. 8 , to be displayed in a selectable manner (in a dark color). The user can select a manufacturer, a type, and a model number of the piece of accessory equipment. Further, in a case of selecting a plurality of pieces of accessory equipment, the user clicks on the add button  806  and repeats selecting. In accordance with the number of sensors thus selected, a display area  807  displays the number of sensors such that “NUMBER OF DEVICES USED IN ACCESSORY EQUIPMENT INFORMATION IS XX”. The above process in which the processor  11  uses the drop-down menu  804  to receive a user operation for specifying a type of the piece of accessory equipment is examples of the first process and the seventh process described above. The above process in which the processor  11  uses the drop-down menu  803  to receive a user operation for specifying a manufacturer of the piece of accessory equipment is an example of the fourth process described above. 
     Subsequently, in a case where the controller  21  has address numbers of the memory, the user designates a beginning address for accessory equipment information. The beginning address for accessory equipment information is information that indicates from which area in the memory  22  of the controller  21  information obtained from a piece of accessory equipment is to be recorded when the information is recorded in the memory  22 . This information is necessary when preparing a memory map (described later). As described above, in a case where the controller  21  is a PLC, the memory area is defined by an alphabetic letter and numbers.  FIG. 8  illustrates a case in which the beginning address for accessory equipment information in the memory  22  is D9000. That is, the user clicks on a drop-down button (an inverted triangular button) of a drop-down menu  808  to select an alphabetic letter “D”. The user then inputs, in a text box  809 , a number “9000” of the address in the memory  22 . The above process in which the processor  11  uses the display screen  800  to receive a user operation for specifying a memory area in the memory  22 , in which memory area data collected from the piece of accessory equipment is to be recorded, is an example of the second process described above. When the user has finished inputting and clicks on a button  810 , information thus inputted is transmitted to the sales device  1 , and a transition to a display screen  900  as illustrated in  FIG. 9  occurs. In a case where the controller  21  does not have address numbers of the memory, it is not necessary to carry out this input process. 
     The display screen  900  is an example of a screen that displays (i) a list of what the user has inputted and (ii) information necessary for setting the relay device  3  so as to allow a purchased piece of equipment to be connected to the Internet. In the display screen  900 , “number of devices used”, “number of IP addresses required”, “number of ports required”, “price”, and “delivery date” are sums of information inputted by the user and an estimated cost and delivery date which are based on the sums. In the display screen  900 , information presented after the message “INFORMATION TO BE SUBMITTED: ENTER FOLLOWING INFORMATION ON DESIGN INFORMATION ENTRY SCREEN” is necessary information which the user must input in order to carry out the setting of the relay device  3 . The necessary information differs between a case in which the user sources the sensor by themselves and a case in which the user collectively purchases the sensor from the company (ZZ Co., Ltd.) manufacturing the relay device  3 . Further, a message is displayed which indicates that a memory map will be generated on the basis of order entries inputted up to the display screen  800 . 
       FIG. 10  is an example of a memory map  1000  generated and outputted by the sales device  1  (processor  11 ). The memory map is a list indicating in which memory area (memory address) in the memory  22  of the controller  21  data collected from the sensor  4  and/or the piece of accessory equipment  5  is to be recorded. With use of the information of the beginning address for sensor information specified by the user on the display screen  700  and the information of the beginning address for accessory equipment information inputted by the user on the display screen  800 , the processor  11  sets the relay device  3  so that the relay device  3  causes data collected from at least one of the sensor and the piece of accessory equipment to be written into the specified memory area. This process is an example of the third process described above. The above process in which the processor  11  generates the memory map  1000  indicating a memory area in the controller  21  and data to be recorded in the memory area is an example of the sixth process described above. Further, the processor  11  may output the memory map  1000  thus generated to a display, a printer, or the like. The memory map  1000  may be written in an instruction manual of the relay device  3 . 
     For example, in a case where “D8000” is inputted as the beginning address for sensor information on the display screen  700  and “D9000” is inputted as the beginning address for accessory equipment information in the display screen  800 , the sales device  1  carries out setting so that the relay device  3  causes predetermined data to be recorded from that memory address. 
     Specifically, as illustrated in  FIG. 10 , the sales device  1  sets the relay device  3  so that the relay device  3  causes “sensor configuration information data” to be recorded in the memory addresses of D8000 to D8059, “sensor communication state data” to be recorded in the memory addresses of D8060 to D8132, “sensor state data” to be recorded in the memory addresses of D8133 to D8252, and “secondary sensor unit monitoring data” to be recorded in the memory addresses of D8253 to D8552. Further, the sales device  1  sets the relay device  3  so that the relay device  3  causes “accessory equipment configuration information data” to be recorded in the memory addresses of D9000 to D9019, “accessory equipment communication state data” to be recorded in the memory addresses of D9020 to D9033, “accessory equipment IF (operation information signal)” to be recorded in the memory addresses of D9034 to D9233, “accessory equipment IF (command signal)” to be recorded in the memory addresses of D9234 to D9433, and “accessory equipment monitoring data” to be recorded in the memory addresses of D9434 to D9633. 
     As described above, the sales device  1  carries out a process of receiving a user operation in order to obtain order details, and an output process based on information thus obtained. The display of screens illustrated are merely examples, and there is no limitation on a manner (displayed items, content, a method of causing the user to carry out inputting or selection, a display position, a display order, a hierarchical structure of display, and the like) in which the screens are displayed. The above examples of operation screens have been described on the assumption that the piece of main equipment  2  is owned by the user and that no piece of main equipment is newly purchased. Note, however, that an operation screen can be displayed which allows the user to input whether or not to purchase a piece of main equipment together with a piece of accessory equipment. 
     With reference to drawings, the following description will discuss an example of a process carried out by the sales device  1  of receiving a user operation in order to obtain setting information of the relay device  3  and an example of an output process carried out by the sales device  1  on the basis of information thus obtained. The setting information is information for connecting the sensor  4  and/or the piece of accessory equipment  5  to the Internet and information of the user&#39;s intended display layout of the monitor screen  6 . 
     The display screen  1100  illustrated in  FIG. 11  is an example of an operation screen for setting network-related information of a primary sensor unit and the controller  21 , which are already in use by the user, and the relay device  3 . Items inputted by the user on the display screen  1100  are a name of a manufacturer of the primary sensor unit and a model number of the primary sensor unit. Specifically, the user inputs information in an input area  1101  for inputting a manufacturer name and an input area  1102  for inputting a model number in an item that reads “SETTING OF PRIMARY SENSOR UNIT”. In  FIG. 11 , up to three primary sensor units can be inputted. Note that an add button for adding a primary sensor unit may be provided. An IP address of the primary sensor unit is pre-assigned and displayed in an area  1103  by default. Note that the address displayed by default may be changed as necessary. Further, a subnet of the IP address is displayed in an area  1104  by default. Only one subnet is displayed because it is assumed that the subnet is shared by the IP addresses of the primary sensor unit, the controller, and a C-BOX. 
     The user inputs a port number in an input area  1106  for inputting a port number in an item that reads “SETTING OF IP ADDRESS AND PORT NUMBER OF CONTROLLER”. In  FIG. 11 , the number of input areas  1106  is four, but this number increases or decreases according to the number of primary sensor units. In an area  1105  for IP address, a pre-assigned IP address is displayed by default. In areas  1107  and  1108  for IP address in an item that reads “SETTING OF C-BOX”, pre-assigned IP addresses of C-BOX are displayed by default. “C-BOX” is an example of a product name of the relay device  3 . In the example illustrated in  FIG. 11 , two areas for an IP address of C-BOX are displayed. This is an example in a case where both a sensor and a piece of accessory equipment are purchased. In a case where only one of a sensor and a piece of accessory equipment is purchased, only one IP address of C-BOX is displayed. 
     When the user has finished inputting and clicks on a button  1109 , information thus inputted is transmitted to the sales device  1 , and a transition to the next display screen occurs. The next display screen varies depending on whether the user is to source the sensor by themselves or collectively purchase the sensor from the manufacturer of the relay device  3 .  FIG. 12  is an example of a display screen  1200 , to which the transition occurs in a case where the user sources the sensor by themselves.  FIG. 13  is an example of a display screen  1300 , to which the transition occurs in a case where the sensor is purchased collectively from the manufacturer of the relay device  3 . 
     On the display screen  1200 , to which the transition occurs in a case where the user sources the sensor by themselves, the user inputs a manufacturer, a type, and a model number of the sensor (secondary sensor unit) sourced by the user themselves in input areas  1201 ,  1202 , and  1203 , respectively. A communication method of the sensor is determined by the model number which has been inputted. As such, any of input areas  1204  and  1205  for inputting an ID number for communication is displayed. In a case where there are a plurality of secondary sensor units, an add button  1207  can be clicked on to display the next input area. When the user has finished all inputting and clicks on a button  1208 , information thus inputted is transmitted to the sales device  1 , and a transition to a display screen  1300  as illustrated in  FIG. 13  occurs. 
     The display screen  1300  illustrated in  FIG. 13  is a display screen for receiving a user operation in which the user sets a display layout of the monitor screen  6  of the relay device  3 . A view  1303  of sections is provided at the center of the display screen  1300 , which view simulates the monitor screen  6 . Types of data to be displayed and example display  1301  of such data are provided in a left part of the display screen  1300 . Example display  1302  of an operation state received from the sensor or the piece of accessory equipment is provided in a right part of the display screen  1300 . 
     The view  1303  of sections is a view of sections obtained by dividing the monitor screen  6  so that square unit sections are arranged in 24 columns by 11 rows. The following display patterns can be placed at any positions in this divided area. 
     In the example display  1301  of data, 17 display patterns each having a size of 4 columns×4 rows are provided. In the uppermost stage, provided are three patterns for displaying a temperature, among which the pattern on the left is in meter format, the pattern in the center is in graph format, and the pattern on the right is in digital value format. In the second stage, provided are three patterns for displaying a humidity, among which the pattern on the left is in meter format, the pattern in the center is in graph format, and the pattern on the right is in digital value format. Likewise, patterns for illuminance are provided in the third stage, patterns for atmospheric pressure are provided in the fourth stage, patterns for noise are provided in the fifth stage, and patterns for vibration are provided in the sixth stage. 
     In the example display  1302  of an operation state, four display patterns each having a size of 4 columns×10 rows are provided. These patterns provided include (i) a pattern that displays, on a monitor, information pertaining to a state of communication with the sensor or the piece of accessory equipment, a power supply voltage of the sensor or the piece of accessory equipment, and an intensity of received radio waves and (ii) an indicator pattern that displays, by a color, a state of the sensor or the piece of accessory equipment. The indicator pattern is set so that, for example, a green light lights up when there is no abnormality, a yellow light lights up when the state of communication is poor, and a red light lights up when there is an abnormality in the power supply voltage or measured data. 
     The user selects a display pattern of data to be displayed on the monitor screen  6  from the example display  1301  of data, and drags and drops the display pattern to a position where the display pattern is to be displayed in the view  1303  of sections. Since the display pattern has a size of 4 columns×4 rows, the display pattern can be placed in an area of that size at any position. Further, the user can designate data to be monitored regarding the state of communication or whether or not there is an abnormality of data, select a display pattern from the example display  1302  of an operation state, and drag and drop the display pattern to a position where the display pattern is to be displayed in the view  1303  of sections. Since any display pattern can be positioned at an empty position in the view  1303  of sections, the user can freely decide which data is to be displayed in what layout. It should be noted that the example display  1301  of data, the example display  1302  of an operation state, and the view  1303  of sections described above are examples and do not imply any limitation. The above process of receiving a user operation is an example of the eighth process described above. 
     When the user finishes designing a layout for the monitor screen  6 , the processor  11  displays an output screen  1400  illustrated in  FIG. 14 . The output screen  1400  is an example of a screen showing a list in which design information of the relay device  3  is summarized. Specifically, the output screen  1400  is a screen for collectively displaying or outputting, to the user, a type(s) and the number of a sensor(s) and/or a piece(s) of accessory equipment to be connected to the network, connection information such as an IP address, a layout of the monitor screen, a price, a delivery date, and the like. 
     (Further Effect of Information Processing Device and Sales Method Thereof) 
     The following description will discuss a case in which, in Embodiment 1 described above, a piece of accessory equipment (e.g., a conveyor, a dust collector, or an electric cylinder) is manufactured by company A, and a sensor or the like is manufactured by company B, as illustrated in  FIG. 15 . In this case, an information processing device (a relay device), which has been set up so as to construct a production system together with both the piece of accessory equipment manufactured by company A and the sensor or the like manufactured by company B, is provided to a system integrator (SIer). This makes it possible to provide an engineering service co-created by the system integrator, company A, and company B. 
     In Embodiment 1, the processor  11  of the sales device  1  has been described as receiving, as the first process or the second process, a user operation at the user terminal T. However, the present invention is not limited to this. For example, the processor  11  may receive, as the first process or the second process, a user operation via an input device connected to the input-output interface  14 . In this case, the processor  11  displays a screen for the first process or the second process on a display connected to the input-output interface  14 .
