  When communication is established between the transfer device 1 and the display device 2 (when communication is possible), the installation / deletion list generation unit 35 determines the type of application software that is currently installed in the storage area 21 and is installed. The list of application software to be installed on the display unit 2 (installation) is checked based on the result of the investigation, the required software database 43, and the version of each application software included in the application software group 32. List) and a list of application software to be deleted (deletion list). If communication is not established between the transfer device 1 and the display device 2, an installation list is created based on the necessary software database 43. Here, the version is written in the contents of the application software file, and the installation / deletion list generation unit 35 refers to the contents of the application software file stored in the storage area 21. The application software version information is acquired, and the version information of the application software included in the transfer apparatus 1 is acquired by referring to each application software file included in the application software group 32.

  The installation / deletion unit 36 executes installation / deletion of application software based on the list generated by the installation / deletion list generation unit 35 when communication between the transfer device 1 and the display device 2 is established. .

  Next, the operation of the transfer apparatus 1 according to the embodiment of the present invention will be described. FIG. 4 is a flowchart for explaining the operation of the transfer apparatus 1.

  First, in step S1, the drawing data input receiving unit 31 receives input of drawing data to be transferred (step S1). Then, the necessary software database creation unit 34 refers to the function setting information included in the received drawing data and determines whether or not a function setting that requires application software is described (step S2). When the function setting that requires the application software is described (Yes in step S2), the necessary software database creation unit 34 refers to the application software information database 33 and sets the function setting described in the function setting information. Corresponding application software is added to the necessary software database (step S3). When the function setting that requires application software is not included (step S2, No), the operation of step S3 is skipped. Then, when there are a plurality of accepted drawing data, the necessary software database creation unit 34 determines whether or not the investigation in step S2 has been executed for all the drawing data (step S4). (S4, No), the process proceeds to step S2, the survey is performed on the unexamined drawing data, and the determination is completed (step S4, Yes), the process proceeds to step S5.

  In step S5, the installation / deletion list generation unit 35 determines whether or not communication is established between the transfer device 1 and the display 2 (step S5). If communication has been established (step S5, Yes), the installation / deletion list generation unit 35 investigates the type and version of application software installed in the storage area 21 of the display device 2 (step S6). Then, the installation / deletion list generation unit 35 determines whether or not content exists in the necessary software database (step S7). If the content exists (step S7, Yes), that is, if there is application software necessary for the received drawing data, an application list of types of application software described in the necessary software database and not installed in the display 2 is installed. (Step S8). Then, the installation / deletion list generation unit 35 determines whether the same kind of application software installed in the display device 2 exists in the necessary software database (step S9). When it exists (step S9, Yes), the installation / deletion list generation unit 35 determines whether or not a difference is recognized in the versions of the same type of application (step S10). When the difference is recognized (step S10, Yes), the application software is added to the installation list (step S11), and the process proceeds to step S12.

  When the content does not exist in the necessary software database in step S7 (step S7, No), or when the same kind of application software installed in the display device 2 does not exist in the necessary software database in step S9 (step S7) (S9, No) or when no difference in version is recognized in the same kind of software in Step S10 (No in Step S10), the process proceeds to Step S12.

  In step S12, the installation / deletion list generation unit 35 determines whether or not unnecessary software is installed in the display device 2 (step S12). Specifically, the installation / deletion list generation unit 35 is not described in the necessary software database, is described in the application software installed in the display device 2 and the necessary software database, and the display device 2 Are recognized as unnecessary application software. If unnecessary software is installed (step S12, Yes), the installation / deletion list generation unit 35 adds the unnecessary application software to the deletion list (step S13). If unnecessary application software has not been installed (step S12, No), step S13 is skipped. Then, the install / delete unit 36 transfers the input drawing data to the storage area 21, reads application software described in the installation list from the application software group 32, and stores the read application software in the storage area 21. Install and delete the application software described in the deletion list from the storage area 21 (step S14). Then, the operation ends.

  In step S5, when the installation / deletion list generation unit 35 determines that communication is not established between the transfer device 1 and the display device 2 (No in step S5), the installation / deletion list generation unit 35 It is further determined whether or not content exists in the necessary software database (step S15). When the content exists (step S15, Yes), the content is added to the installation list (step S16), and the operation ends. If no content exists (step S15, No), the operation ends. When communication is established between the transfer device 1 and the display device 2 later, the install / delete unit 36 transfers the input drawing data to the storage area 21 and adds it to the install list created in step S16. The described application software may be read from the application software group 32 and the read application software may be installed in the storage area 21.

  Before performing installation / deletion in step S14, an installation list and a deletion list are displayed on the display unit 15 to prompt editing of each list, and the process of step S14 is executed based on the edited list. It may be. FIG. 5 is a diagram for explaining a display example of an installation list. As shown in the figure, a check box is displayed before the display of the name of each application software, and the check box is checked in the top check box of the application software that needs to be installed. The user can edit the installation list by unchecking or checking a check box of another application software. Then, the installation is started by pressing the “write” button at the lower right of FIG. 5 with a pointing device or the like of the input unit 14. FIG. 6 is a diagram for explaining a display example of a deletion list. As shown in the figure, names of unnecessary application software are displayed in a list, and a check box is drawn in front of each name. The user checks the check box of the application software to be deleted, and presses an “OK” button drawn at the bottom thereof, so that the deletion is started. When the “Cancel” button is pressed, deletion is not performed.

  As described above, according to the present embodiment, the application software information that associates the function setting that can be set in the drawing data with the application software that is required to realize the function setting in the programmable display 2 for each function setting. Based on the database, create a required software database, which is a list of application software required to realize the function settings included in the received drawing data, and list the application software to be installed based on the created required database An installation list that is information is generated, application software described in the installation list is read from the application software group 32, and the read application software is installed in the programmable display 2. Since it is configured, it becomes possible to automatically select the application software needed to implement the function setting included in drawing data to be transferred to the programmable display device 2. If there is application software described in the necessary software database and installed in the programmable display device 2, the version of the application software in the application software group 32 and the installed application software for this application software If both versions are different, this application software is configured to be installed, so it can be upgraded automatically, so the user can visually check the version and install it. There is no need to select software. In addition, it is not necessary because it is configured so that application software that is not described in the required software database among the installed application software is added to the deletion list, and the application software described in the deletion list is deleted from the programmable display device 2. Since it is possible to automatically delete necessary application software, it is possible to prevent a user from accidentally deleting necessary application software. Since the installation list is configured to be editable, the user can manually select application software to be installed. Since the deletion list is configured to be editable, the user can manually select application software to be deleted.

  In the above description, the version is written in the contents of the application software file, and the installation / deletion list generation unit 35 refers to the contents of the application software file stored in the storage area 21. The version information of the application software is acquired by this, and the version information of the application software that the transfer apparatus 1 has is acquired by referring to the file of each application software that the application software group 32 has. However, the version information may be included in the identification information of the application software.
