[Functions Implemented by the Industrial Machine Management System S According to the Embodiment of the Present Invention]
[Functions Implemented by the Maintenance-Use Portable Terminal 30]
First, a description is made of the functions provided to the maintenance-use portable terminal 30. As illustrated in
The input reception unit 31 receives an input from the user based on, for example, the user's operation performed by the user on the operating unit 30e. The input reception unit 31 may receive, from the user, individual identification information (serial number) on an industrial machine, designation of user setting information (for example, facility name, device name, file name containing a parameter, serial number of another industrial machine serving as a connection destination of the industrial machine) set for the industrial machine by the user, and a request for registration, viewing, or the like of the designated information. The input reception unit 31 outputs the information received from the user to the data communication unit 35, and transmits the information received from the user to the cloud server 60 by the data communication unit 35.
The display control unit 32 displays various screens such as a screen for displaying information on an industrial machine to be managed and a screen for registering the information on the industrial machine on the display unit 30d based on the information received by the input reception unit 31 and based on the information received by the data communication unit 35.
The code image acquisition unit 33 picks up an image of a code image formed, printed, or attached on the industrial machine (controller 40, motor control device 10, or motor 1) by the camera provided to the maintenance-use portable terminal 30, for example, to acquire the code image. Note that, in this embodiment, the individual identification information (serial number) on the industrial machine may be encoded in the code image.
The individual identification information acquisition unit 34 acquires the individual identification information (serial number) on the industrial machine to be processed. For example, the individual identification information acquisition unit 34 may acquire the individual identification information (serial number) on the industrial machine to be processed, based on the code image input from the code image acquisition unit 33 or the individual identification information designated by the user and input from the input reception unit 31. For example, when the code image is input from the code image acquisition unit 33, the individual identification information acquisition unit 34 may decode the input code image to acquire the individual identification information (serial number) encoded in the code image.
The data communication unit 35 transmits/receives data to/from a computer (for example, cloud server 60) to/from which the maintenance-use portable terminal 30 communicates. For example, the data communication unit 35 transmits the information received by the input reception unit 31 and the individual identification information acquired by the individual identification information acquisition unit 34 to the cloud server 60 in accordance with the user's operation received by the input reception unit 31, to request the cloud server 60 to perform processing, and receives a processing result from the cloud server 60 to visually output the received processing result by the display control unit 32.
[Functions Implemented by the Cloud Server 60]
Next, a description is made of the functions provided to the cloud server 60 according to this embodiment. As illustrated in
The user information storage unit 601 stores a user information database for storing various kinds of information on a user (including corporation). For example, the user information database stores a user ID for uniquely identifying the user, a password, and personal information (corporation information) on each user. When the user performs a predetermined user registration, a new record is created in the user information database, and the information input by the user who has performed the user registration is stored in the record. The information stored in the user information database may be changed in response to each user's request.
The machine information storage unit 602 stores a machine information database for storing various kinds of information on the industrial machine. In this embodiment, the machine information storage unit 602 stores a first machine information database for storing information on an industrial machine made by a predetermined maker whose production is managed by the production management server 80 and a second machine information database for managing information on an industrial machine made by a maker other than the predetermined maker. In the user's facility, not only an industrial machine made by a predetermined maker but also an industrial machine made by a maker other than the predetermined maker may coexist, and hence the second machine information database for managing the industrial machine made by the maker other than the predetermined maker is held in addition to the first machine information database for managing the information on the industrial machine made by the predetermined maker, to thereby allow the information on the user's industrial machine system to be centrally managed even in an environment in which industrial machines made by various makers coexist.
The maker area stores the maker management information (unique information on an industrial machine independent of a user's environment) managed by the maker for an industrial machine. For example, the maker management information includes a product name of the industrial machine, a model thereof, product descriptions relating to specifications, a manufacturing date, and a kind and version information on firmware. Note that, the kind and version information on the firmware within the maker area may be appropriately changed when the firmware is downloaded or updated. On the other hand, the information other than the kind and version information on the firmware may be invariable in principle. Further, when the industrial machine is purchased after being customized, the maker area may further store a customization ID for identifying details of the customization.
The user area stores the user management information managed by the user for the industrial machine. For example, the user management information may include at least one combination of an item and data on the item for each of the industrial machines. The items that can be set in the user management information may be freely set by the user, and at least one of, for example, “facility name”, “device name”, “purpose”, “connection destination (parent)”, “connection destination (child)”, “profile”, or the like may be set as an initial item in advance. Note that, the “facility name” represents a name of a facility in which the industrial machine is placed. The “device name” represents a name of a device configured by combining a plurality of industrial machines. The “purpose” represents information describing a purpose of the industrial machine. The “connection destination (parent)” represents a parent industrial machine (for example, industrial machine on a side of managing the industrial machine) connected to the industrial machine (by wiring). The “connection destination (child)” represents a child industrial machine (for example, industrial machine managed by the industrial machine) connected to the industrial machine (by wiring). The “profile” represents data on a unique parameter set, which is set for the industrial machine. A content of item and a number of the items stored in the user area may be changed in response to the user's request, and may differ between individual industrial machines.
The information stored in the user area within the second machine information database may be set arbitrarily by the user. For example, in the user area, at least one of the items including the product name, the model, the product descriptions, the manufacturing date, the kind and version information on firmware, the facility name, the device name, the purpose, the connection destination (parent), the connection destination (child), and the profile may be set as an initial item in advance. Note that, also in the second machine information database, the user area may have the same feature as that of the first machine information database.
The maker management information registration unit 603 registers the maker management information on the industrial machine in the first machine information database. For example, when the industrial machine whose order has been placed by the user is produced, the maker management information registration unit 603 creates a new record in the first machine information database, and stores the serial number of the industrial machine, the owner thereof, and each piece of information included in the maker area. Note that, for example, the maker management information registration unit 603 may acquire those pieces of information from the production management server 80 to register the information.
The data communication unit 604 transmits/receives data to/from a computer (for example, the maintenance-use portable terminal 30) to/from which the cloud server 60 communicates. For example, based on the received data, the data communication unit 604 may sort and output the data to the user authentication unit 605, the user management information reception unit 606, the individual identification information reception unit 610, or the system identification information reception unit 612.
The user authentication unit 605 executes user authentication processing based on user authentication information received from the maintenance-use portable terminal 30 through the data communication unit 604. For example, when the user authentication information (user ID and password) is received by the data communication unit 604, the user authentication unit 605 may receive an input of the user authentication information from the data communication unit 604, and execute the user authentication processing based on whether or not the input user authentication information (user ID and password) matches the user ID and the password stored in the user information storage unit 601.
The user management information reception unit 606 receives the user management information from the maintenance-use portable terminal 30 through the data communication unit 604. For example, when the individual identification information (serial number) on the industrial machine and the user management information (information including the combination of the item and the data on the item) is received by the data communication unit 604, the user management information reception unit 606 may receive the inputs of the individual identification information (serial number) and the user management information from the data communication unit 604.
The user management information writing unit 607 writes the user management information received by the user management information reception unit 606 into the record corresponding to the individual identification information received by the user management information reception unit 606, based on the individual identification information (serial number) and the user management information received by the user management information reception unit 606. For example, the user management information writing unit 607 searches the machine information database (machine information database is assumed to be a database including both the first machine information database and the second machine information database) stored in the machine information storage unit 602 for the corresponding record with the serial number received by the user management information reception unit 606 as a key. The user management information writing unit 607 writes the user management information received by the user management information reception unit 606 into the user area of the above-mentioned retrieved record. In this case, when an item included in the user management information received by the user management information reception unit 606 already exists in the record corresponding to the serial number received by the user management information reception unit 606, the user management information writing unit 607 updates the information on the item that already exists. Further, when the item included in the user management information received by the user management information reception unit 606 does not exist, the user management information writing unit 607 may newly add the item, and then write the information into the added item.
In this embodiment, when the user management information received by the user management information reception unit 606 includes at least one of the item of the connection destination (parent) or the item of the connection destination (child), the user management information writing unit 607 outputs those items and the data (serial number) on the items to the already-registered state determination unit 608 along with the serial number received by the user management information reception unit 606.
When receiving the items (connection destination (parent) and connection destination (child)) and the data (serial number) on the items from the user management information writing unit 607, the already-registered state determination unit 608 determines whether or not the received serial number has already been registered in a serial number field of the machine information database stored in the machine information storage unit 602. When determining that the serial number received from the user management information writing unit 607 has not been registered in the serial number field of the machine information database, the already-registered state determination unit 608 outputs the items (connection destination (parent) and connection destination (child)) and the data (serial number; hereinafter referred to as “connection destination serial number”) on the items received from the user management information writing unit 607 to the record adding unit 609 along with the serial number (hereinafter referred to as “connection source serial number”) of the record to which the user management information is written by the user management information writing unit 607.
When receiving the inputs of the items (connection destination (parent) and connection destination (child)) and the data (connection destination serial number) on the items from the already-registered state determination unit 608 along with the input of the connection source serial number, the record adding unit 609 newly adds a record to the second machine information database. Then, the record adding unit 609 writes the received connection destination serial number into the serial number field of the added record. In addition, when the item input from the already-registered state determination unit 608 is the connection destination (parent), the record adding unit 609 adds the item of the connection destination (child) to the user area, and writes the connection source serial number as the data on the item of the connection destination (child). Further, when the item input from the already-registered state determination unit 608 is the connection destination (child), the record adding unit 609 adds the item of the connection destination (parent) to the user area, and writes the connection source serial number as the data on the item of the connection destination (parent).
The individual identification information reception unit 610 receives the individual identification information from the maintenance-use portable terminal 30 through the data communication unit 604. For example, when the individual identification information (serial number) is received by the data communication unit 604 along with a request for viewing of detailed information on the industrial machine, the individual identification information reception unit 610 may receive the individual identification information (serial number) from the data communication unit 604.
The machine information providing unit 611 provides the management information stored in association with the individual identification information (serial number) received by the individual identification information reception unit 610. For example, the machine information providing unit 611 searches the machine information database for the corresponding record with the serial number received by the individual identification information reception unit 610 as a key. The machine information providing unit 611 may provide the management information stored in the above-mentioned retrieved record to a source of the request for the viewing of the detailed information on the industrial machine through the data communication unit 604. Note that, the above-mentioned management information may be set as at least a part of the information stored in the maker area and the user area when the maker area exists, and may be set as at least a part of the information stored in the user area when the maker area does not exist.
The system identification information reception unit 612 receives industrial machine system identification information for identifying one industrial machine system formed of a plurality of industrial machines from the maintenance-use portable terminal 30 through the data communication unit 604. The industrial machine system identification information may be set as, for example, the individual identification information (serial number) on one industrial machine that forms the industrial machine system. For example, when the industrial machine system identification information is received by the data communication unit 604 along with a request for viewing of configuration information on the industrial machine system, the individual identification information reception unit 610 may receive the industrial machine system identification information from the data communication unit 604. The system identification information reception unit 612 outputs the received industrial machine system identification information to the system configuration information generation unit 613.
The system configuration information generation unit 613 generates system configuration information including the information on each of the plurality of industrial machines that form the industrial machine system based on the industrial machine system identification information input from the system identification information reception unit 612. For example, based on the information on the connection destination (parent) and the connection destination (child) of each record stored in the machine information database, the system configuration information generation unit 613 searches for at least one industrial machine connected to the industrial machine having the serial number included in the industrial machine system identification information directly or through another industrial machine, and generates a list including information on the retrieved industrial machine as the configuration information on the industrial machine system. Note that, the above-mentioned list may be set as a list including the industrial machine designated by the industrial machine system identification information and the retrieved industrial machine. Then, based on the information on the connection destination of the industrial machine included in the above-mentioned generated list, the system configuration information generation unit 613 may generate a wiring diagram of the industrial machine system, and provide the generated wiring diagram. Note that, processing for generating the configuration information on the industrial machine system is described later in detail.
The system configuration information providing unit 614 provides the configuration information on the industrial machine system generated by the system configuration information generation unit 613 to a source of the request for the viewing of the configuration information on the industrial machine system through the data communication unit 604.
[Processing Executed in the Industrial Machine Management System S]
Next, an example of processing executed in the industrial machine management system S is described with reference to
[Processing for Displaying Detailed Information on Industrial Machine]
First,
As illustrated in
When receiving the authentication information the maintenance-use portable terminal 30 from through the communication unit 30c, the cloud server 60 executes user authentication based on the received authentication information (S103). When the above-mentioned authentication fails (N in S103), the cloud server 60 notifies the maintenance-use portable terminal 30 of an error (S104), and brings the processing to an end. When the above-mentioned authentication is successful (Y in S103), the cloud server 60 notifies the maintenance-use portable terminal 30 of successful authentication (S105), and permits a processing request to be received from the maintenance-use portable terminal 30.
After receiving the notification of the successful authentication from the cloud server 60, the maintenance-use portable terminal 30 acquires the serial number of the industrial machine whose detailed information is to be viewed (hereinafter referred to as “target machine”) based on the user's input through the operating unit 30e or the code image picked up by the camera 30f (S106). The maintenance-use portable terminal 30 transmits the above-mentioned acquired serial number to the cloud server 60 (S107), and requests the detailed information on the industrial machine corresponding to the serial number.
The cloud server 60 searches the machine information database (database including both the first machine information database and the second machine information database) stored in the machine information storage unit 602 for the record that stores the above-mentioned received serial number in the serial number field, with the serial number received from the maintenance-use portable terminal 30 as a key. The cloud server 60 acquires the information stored in the above-mentioned retrieved record as machine information linked to the above-mentioned received serial number (S108). Note that, the cloud server 60 may cause the machine information to include all pieces of information included in the above-mentioned retrieved record, or may extract a part of the information stored in the above-mentioned retrieved record so as to be included in the machine information.
Subsequently, the cloud server 60 transmits the machine information on the target machine acquired in Step S108 to the maintenance-use portable terminal 30 (S109).
The maintenance-use portable terminal 30 receives the machine information on the target machine from the cloud server 60. Then, the maintenance-use portable terminal 30 displays a machine information display screen for displaying the above-mentioned received machine information (refer to, for example,
Next, processing for registering the user management information executed when the edit button 514 is pressed on the machine information display screen 510 illustrated in
[Processing for Registering User Management Information on Industrial Machine]
As illustrated in
The cloud server 60 receives the edit request for the user management information on the target machine from the maintenance-use portable terminal 30. Then, the cloud server 60 transmits display data for displaying an edit screen for the user management information linked to the serial number relating to the edit request, to the maintenance-use portable terminal 30 (S203).
Based on the display data received from the cloud server 60, the maintenance-use portable terminal 30 displays an edit screen for editing the user management information (hereinafter referred to as “user management information edit screen”, refer to
The maintenance-use portable terminal 30 receives the setting of an item to be registered (registration item) through the user management information edit screen 500 (S205). In addition, the maintenance-use portable terminal 30 receives data to be set for the registration item (registration data) through the user management information edit screen 500 (S206). For example, the maintenance-use portable terminal 30 may receive the “connection destination (parent)” as the registration item, and the serial number serving as the individual identification information on the industrial machine serving as the connection destination (parent) as the registration data. Then, the maintenance-use portable terminal 30 receives a registration instruction from the user when the registration button 504 is pressed on the user management information edit screen 500 (S207). Then, the maintenance-use portable terminal 30 transmits the user management information including the item set on the user management information edit screen 500 and the data on the item to the cloud server 60 along with the serial number of the target machine (S208), and requests the updating of the user management information on the target machine.
The cloud server 60 receives the user management information and the serial number from the maintenance-use portable terminal 30. Then, the cloud server 60 executes processing for updating the machine information database based on the above-mentioned received data (S209). The processing for updating the machine information database is described in detail with reference to a flowchart illustrated in
[Processing for Updating the Machine Information Database]
As illustrated in
When the user area of the record identified in Step S301 does not include the registration item included in the user management information received from the maintenance-use portable terminal 30, the cloud server 60 adds the registration item (S302). The cloud server 60 writes the registration item and the registration data included in the user management information into the user area of the record identified in Step S301 in association with each other (S303).
Subsequently, when the registration item written into the user area of the record is not the connection destination (at least one of connection destination (parent) or connection destination (child)) (N in S304), the cloud server 60 finishes the processing for updating the machine information database. When the registration item written into the user area of the record is the connection destination (Y in S304), the cloud server 60 determines whether or not the serial number newly stored for the item of the connection destination has already been registered in the serial number field of the machine information database (S305).
When it is determined in Step S305 that the serial number (serial number of the connection destination) newly stored for the item of the connection destination has already been registered in the serial number field of the machine information database (Y in S305), the cloud server 60 identifies the record linked to the serial number of the connection destination from the machine information database (S306). When the above-mentioned identified record does not include the registration item, the cloud server 60 adds the registration item (S307), writes the serial number of the target machine into the registration item (S308), and finishes the processing for updating the machine information database. Note that, the above-mentioned registration item may be set as the connection destination (child) when the item registered for the target machine is the connection destination (parent), and may be set as the connection destination (parent) when the item registered for the target machine is the connection destination (child).
On the other hand, when it is determined in Step S305 that the serial number (serial number of the connection destination) newly stored for the item of the connection destination has not been registered yet in the serial number field of the machine information database (N in S305), the cloud server 60 adds the record to the second machine information database (S309). The cloud server 60 adds the registration item to the added record (S310), writes the serial number of the target machine into the registration item (S311), and finishes the processing for updating the machine information database. The above-mentioned registration item may be set as the connection destination (child) when the item registered for the target machine is the connection destination (parent), and may be set as the connection destination (parent) when the item registered for the target machine is the connection destination (child).
Now, description is continued by returning to the sequence diagram of
When receiving the notification of the completion of the update from the cloud server 60, the maintenance-use portable terminal 30 updates the display of at least one of the user management information edit screen 500 or the machine information display screen 510 on the target machine (S211). When registration of information on the target machine is not to be finished (N in S212), the maintenance-use portable terminal 30 returns to Step S205. In a case where the registration of information on the target machine is to be finished (for example, the finish button 505 is pressed on the user management information edit screen 500) (Y in S212), when the information on another machine is to be further displayed/registered (Y in S213), the maintenance-use portable terminal 30 returns to Step S106 of
The processing for displaying the management information (including maker management information and user management information) on the target machine designated by the user by using the maintenance-use portable terminal 30 and the processing for updating the user management information on the target machine have been described above.
[Processing for Providing Configuration Information on the Industrial Machine System]
Next, an example of processing for generating/providing the configuration information on the industrial machine system (device) including the target machine is described with reference to a flowchart illustrated in
As illustrated in
Subsequently, the cloud server 60 identifies the record of the machine of interest from the machine information database with the serial number of the machine of interest as a key (S403). Here, the cloud server 60 determines whether or not the industrial machine serving as the connection destination (parent) exists for the machine of interest based on the user management information of the record identified in Step S403 (S404). For example, the cloud server 60 may determine that the industrial machine serving as the connection destination (parent) exists when the serial number is stored in a data area of the item of the connection destination (parent) within the user management information of the record identified for the machine of interest. Further, the cloud server 60 may determine that the industrial machine serving as the connection destination (parent) does not exist when the item of the connection destination (parent) does not exist or when the serial number is not stored in the data area of the item of the connection destination (parent).
When determining in Step S404 that the industrial machine serving as the connection destination (parent) connected to the machine of interest exists (Y in S404), the cloud server 60 sets the stored serial number as a new machine of interest (S405), and returns to Step S403. Further, when the serial number is stored for the item of the connection destination (parent) within the user management information of the record identified for the machine of interest, the cloud server 60 may determine the industrial machine serving as the connection destination (parent) connected to the machine of interest exists.
On the other hand, when determining in Step S404 that the industrial machine serving as the connection destination (parent) does not exist for the machine of interest (N in S404), the cloud server 60 determines that the machine of interest is a top-level machine in the industrial machine system, and adds the serial number of the machine of interest to a device list (S406). Further, when the item of the connection destination (parent) does not exist in the user management information of the record identified for the machine of interest or when the serial number is not stored in the data area of the item of the connection destination (parent), the cloud server 60 may determine that the industrial machine serving as the connection destination (parent) does not exist for the machine of interest. Note that, the cloud server 60 may store a processing completion flag (true-false value indicating a processed state by true and an unprocessed state by false) in association with each serial number to be added to the device list, and in this case, the processing completion flag is set to have an initial value of the unprocessed state (false).
Subsequently, the cloud server 60 selects the serial number in an unprocessed state from among the serial numbers (industrial machines) included in the device list (S407). The cloud server 60 adds, to the device list, the serial number stored for the item of the connection destination (child) within the user management information of the record identified from the machine information database with the above-mentioned selected serial number as a key (S408). Then, the cloud server 60 updates the processing completion flag for the serial number selected in Step S407 to the processed state (true) (S409).
When the serial number (industrial machine) in an unprocessed state exists in the device list after Step S409 (Y in S410), the cloud server 60 returns to Step S407 to repeat the subsequent processing. When the serial number (industrial machine) in an unprocessed state does not exist in the device list (N in S410), the cloud server 60 generates the system configuration information based on the serial number included in the device list and the management information stored in the machine information database in association with each serial number (S411). For example, the system configuration information may include the information such as the serial number, the product name, the model, the facility name, the device name, the connection destination (parent), and the connection destination (child) for each of the plurality of industrial machines that form the industrial machine system.
Then, the cloud server 60 provides (transmits) the system configuration information generated in Step S411 to the terminal from which the processing request has been received (for example, maintenance-use portable terminal 30) (S412), and brings the processing to an end. Note that, the terminal that has received the system configuration information from the cloud server 60 may display the system configuration information.
Here,
For example, when the button 522 is pressed on the system configuration information display screen 520, the terminal requests the cloud server 60 to generate the wiring diagram, and the cloud server 60 generates data on the wiring diagram illustrated in, for example,
Note that, the wiring diagram illustrated in
According to the industrial machine management system S described above, the user management information set by the user for each piece of individual identification information on the industrial machine is stored in the cloud server 60 in association, to thereby allow the cloud server 60 to collectively manage the user management information set for each industrial machine. This facilitates the sharing of the user management information according to the industrial machine management system S.
Further, the maker area serving as the storage area for writing the management information set by the maker for each piece of individual identification information on the industrial machine and the user area serving as the storage area for writing the management information set by the user are provided, which allows the maker area to hold the management information that does not depend on the user's environment for the individual industrial machine. Further, the information stored in the maker area is inhibited from being changed by the user, which can guarantee property and invariance of the information within the maker area.
Further, the cloud server 60 provides the management information stored in the machine information database for the individual identification information on the industrial machine designated by the user, which allows the user to view the management information on the designated industrial machine.
Further, in the user management information, data on at least one of at least one item designated by the user or at least one item designated in advance is stored in association with each of the individual industrial machines, which allows the setting of the user management information having contents corresponding to the user's environment in which the individual industrial machine is placed.
Further, in the user management information, the identification information on another industrial machine serving as the connection destination connected through a wiring (including, for example, electric wire or signal line) is stored in association with each of the individual industrial machines, which allows the connection relation between the individual industrial machines in the user's environment to be managed based on the user management information on the individual industrial machines.
Further, when the user management information in which the industrial machine serving as the connection destination of the industrial machine to be registered is designated is received from the terminal operated by the user, in a case where the individual identification information on the industrial machine of the designated connection destination has already been registered in the machine information database, the cloud server 60 can write the individual identification information on the industrial machine to be registered, as the connection destination, into the user management information managed by the machine information database for the individual identification information on the industrial machine of the designated connection destination. This allows the connection relation to be associated with both the industrial machines that are in a connection relation.
Further, when the user management information in which the industrial machine serving as the connection destination of the industrial machine to be registered is designated is received from the terminal operated by the user, in a case where the individual identification information on the industrial machine of the designated connection destination is not registered in the machine information database, the cloud server 60 newly adds the record for the individual identification information on the industrial machine of the designated connection destination to the machine information database, to thereby be able to manage the information even when the industrial machine is not registered in the machine information database. Further, the individual identification information on the industrial machine to be registered is added, as the connection destination, to the individual identification information on the user management information managed by the machine information database for the newly added industrial machine, which allows the connection relation to be associated with both the industrial machines that are in a connection relation. Further, the user management information set by the user can be managed by the cloud server 60 also for the newly added industrial machine.
Further, the cloud server 60 can generate the configuration of a device formed of a plurality of industrial machines including the industrial machine designated by the user, based on the information on the industrial machine identified after a search based on the information on the connection destination stored in the machine information database for the designated industrial machine, and can provide the user therewith. In addition, the cloud server 60 can also generate the wiring diagram of the device formed of the plurality of industrial machines, based on the information on the connection destinations of the plurality of industrial machines included in the device, and can provide the user therewith.
[Modification Example]
Note that, the present invention is not limited to the above-mentioned embodiment. For example, the above-mentioned embodiment is described by taking the example in which the user terminal for acquiring and registering the data to be stored in the machine information database is the maintenance-use portable terminal 30, but the motor control device maintenance terminal 20, another personal computer, or the like may be used as the user terminal. For example, when the motor control device maintenance terminal is used as the user terminal, the motor control device maintenance terminal may acquire a parameter file storing parameter information from the motor control device to be controlled. Then, the motor control device maintenance terminal may register the above-mentioned acquired parameter file in the cloud server 60 in association with the individual identification information on the motor control device to be controlled. Here, for example, when the industrial machine to be managed is a motor, the parameter file may store (1) a kind (for example, rotary type or linear type) of the motor 1, (2) model information (for example, model number) of the motor 1, and (3) the parameter information relating to the motor 1. Note that, the parameter information may store parameter information corresponding to the kind of the motor 1. For example, in the case of the rotary type, the parameter information may store a rated torque, a rated power, a rated rotational speed, an instantaneous maximum torque, a motor inertia moment, a pole number, a highest rotational speed, a rated current, a maximum current, and d-axis and q-axis inductances. In the case of the linear type, the parameter information may store a maximum thrust, a rated thrust, a moving coil mass, a rated speed, a highest speed, a pole pitch, a rated current, a maximum current, and d-axis and q-axis inductances.
Further, the above-mentioned embodiment is described by taking the example in which the information on the industrial machine (for example, product made by a predetermined maker) managed by the production management server 80 is managed by the first machine information database while the information on the other industrial machines is managed by the second machine information database, but the information on all the industrial machines may be managed by the first machine information database. In the case, for the industrial machine managed by the second machine information database in the above-mentioned embodiment, the maker area may be blank, and all pieces of management information may be stored in the user area.
Further, the above-mentioned embodiment is described by taking the example in which another industrial machine that forms the industrial machine system including the designated industrial machine is determined based on the serial number of an industrial machine serving as the connection destination included in the user management information on the industrial machine, but a plurality of industrial machines (industrial machine group) that form the industrial machine system may be extracted based on conditions such as a designated device name.
Further, when various kinds of data are transmitted/received between the industrial machine (for example, controller 40) connectable to the network N and each server (for example, cloud server 60), different kinds of communications protocol can be employed, and a file transfer protocol (FTP) may be used as an example thereof.
For example, a function of a FTP client may be implemented on an industrial machine, and a function of a FTP server may be implemented on a server. In this case, the above-mentioned server functioning as the FTP server stands by for a communication connection request based on the FTP from the industrial machine functioning as the FTP client. When the industrial machine performs the communication connection request to the server, the industrial machine can transfer data and a program (for example, setting information on the industrial machine, firmware, and logging data in which an operational situation and the like of the industrial machine are recorded) stored in its own storage unit to the server as a file to be transferred, and record the file in a storage unit on a server side. In addition, the industrial machine can acquire data and a program (for example, setting information on the industrial machine or another industrial machine and firmware) stored in the storage unit on the server side as a file to be transferred, and record the file in its own storage unit. With this configuration, the industrial machine can perform the data transfer between its own storage unit and the storage unit on the server side at an arbitrary timing.
Further, in contrast to the above-mentioned configuration, the function of the FTP server may be implemented on the industrial machine, and the function of the FTP client may be implemented on the server. In this case, the industrial machine functioning as the FTP server stands by for the communication connection request based on the FTP from the server functioning as the FTP client. When the server performs the communication connection request to the industrial machine, the server can transfer data and a program (for example, setting information on the industrial machine or another industrial machine and firmware) stored in the storage unit on the server side to the industrial machine as a file to be transferred, and record the file in the storage unit of the industrial machine. In addition, the server can acquire data and a program (for example, setting information on the industrial machine, firmware, and logging data) stored in the storage unit of the industrial machine as a file to be transferred, and record the file in its own storage unit. With this configuration, the server can perform the data transfer between the storage unit on the server side and the storage unit of the industrial machine at an arbitrary timing.
Note that, when the file transmitted/received in the above-mentioned manner is data stored in the user area of the machine information, the data registered in the user area by each user can be acquired from the server by the industrial machine, and can be transferred from the server to the industrial machine, at an arbitrary timing.
It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and alterations may occur depending on design requirements and other factors insofar as they are within the scope of the appended claims or the equivalents thereof.
