Description

  The present invention relates to a screen data conversion device that converts screen data of a control display device, a program thereof, and a recording medium.

  Conventionally, as a control system HMI (Human Machine Interface), by changing screen data stored in advance, a device for displaying a state on the operation screen, a device state display method, and an operation on the operation screen Programmable displays that can change the device whose state is controlled when accepted are widely used.

  Furthermore, when displaying a character string based on the screen data, the programmable display shown in Patent Document 1 to be described later refers to the character string table, specifies the character string to be displayed on the screen, and displays the character string. Prior to this, a character string table to be referred to when a character string is displayed can be set.

JP 2000-194472 A (publication date: July 14, 2000)

  However, in the above conventional configuration, by using the screen data generated so as to refer to the character string table, the programmable display device is made compatible with multiple languages. There is a problem in that it takes time to newly create screen data in such a format.

  The present invention has been made in view of the above problems, and an object of the present invention is to realize a screen data conversion apparatus capable of relatively easily generating screen data compatible with multilingual display. It is in.

  In order to solve the above-described problem, the screen data conversion device according to the present invention includes a data unit that instructs the display device for control to display the display elements constituting the screen. From the screen data stored in the storage device, the screen data conversion device Among the data units, an extracting unit that extracts a non-indexed data unit that includes a character string and instructs the control display device to display the character string, and each non-indexed data unit extracted by the extracting unit A character string table updating means for updating a character string table stored in the storage device and referred to by a data unit included in the screen data so as to include the included character string; and each non-extracted by the extracting means. The indexed data unit is the character string table of the character string included in the non-indexed data unit. Data unit conversion means for converting the display of the character string stored at the position in the character string table into an indexed data unit that instructs the control display device. It is characterized by that.

  In the configuration, the non-indexed data unit is extracted from the screen data stored in the storage device by the extraction unit, and the character string table of the storage device stores the character string included in the non-indexed data unit. Updated to include. The non-indexed data unit is converted into a non-indexed data unit including position information of a character string included in the character string table by the data unit conversion means.

  As a result, the display device for control displays the screen data before conversion, that is, the non-indexed data unit by displaying the screen based on the screen data after conversion, that is, the screen data not including the non-indexed data unit. The same screen as that displayed based on the screen data included can be displayed. Therefore, screen data that does not include non-indexed data units is easier than the case where the screen designer of the control display device designs a new screen so that the screen data does not include non-indexed data units. Can be generated. On the other hand, the indexed data unit, unlike the non-indexed data unit, contains the position information of the character string, not the character string itself, so it can be used for control based on the screen data simply by changing the character string table. The character strings displayed on the display device can be changed collectively. Therefore, unlike screen data that needs to be changed in order to display a plurality of languages, such as screen data including non-indexed data units, it is possible to handle multilingual display relatively easily. As a result, it is relatively easy to generate screen data that can handle multilingual display.

  Further, in addition to the above configuration, the character string table updating means may include the character string already included in the character string table before adding the character string included in the non-indexed data unit to the character string table. The character string may be added to the character string table only when it is not included.

  In this configuration, when the screen data includes a plurality of non-indexed data units that display the same character strings, the character strings corresponding to the non-indexed data units are not added to the character string table. Since only one is added to the character string table, the total amount of data required to store the screen data and the character string table can be reduced as compared with the case where each is added. Since these non-indexed data units are converted into indexed data units that include the same position information, the display device for control can refer to these indexed data units without any trouble. The same character string can be displayed.

  Further, in addition to the above configuration, before outputting the screen data including the converted indexed data unit and the updated character string table, the character strings included in the character string table are rearranged and arranged. A rearrangement unit that updates the position information included in the indexed data unit in accordance with the change may be provided.

  In this configuration, the character string table and the screen data after being rearranged by the rearranging unit are output. Therefore, even if a device capable of displaying the contents of the character string table (for example, a screen data and character string table editing device) does not have the function of rearranging the character strings in the character string table, By displaying the screen data and the character string table output from the screen data conversion device, the device can present the rearranged character string table to the user, and can present related character strings collectively.

  Further, in addition to the above configuration, an e-mail generation unit that generates an e-mail in which the updated character string table is attached as an attached file may be provided.

  Here, when multilingual screens containing character strings in a certain language, it is necessary to translate from the original language to another language, but the user who created the screen data in the original language You may not be proficient in any language. Therefore, in many cases, translation or a check of the character string after translation is requested to others. On the other hand, the screen data conversion apparatus having the above-described configuration includes an e-mail generation unit, and can generate an e-mail attached with the updated character string table. Therefore, it is possible to reduce the trouble of sending an e-mail attached with a character string table and requesting translation to others.

  By the way, although the said screen data converter may be implement | achieved only by hardware, you may implement | achieve it, when a computer runs a program. Specifically, the program according to the present invention is a program that causes a computer capable of accessing the storage device to operate as each unit of each screen data conversion device. The program is recorded on the recording medium according to the present invention.

  When these programs are executed by the computer, the computer operates as the screen data conversion device. Therefore, as with the screen data conversion apparatus described above, it is relatively easy to generate screen data that can be displayed in multiple languages.

  Non-indexed from screen data including non-indexed data units without redesigning the screen so as not to include non-indexed data units by the screen data conversion apparatus according to the present invention, and its program and recording medium Since it can be converted into screen data that does not include a data unit, it is relatively easy to generate screen data that can be displayed in multiple languages.

  An embodiment of the present invention will be described below with reference to FIGS. That is, the control system according to the present embodiment can handle multilingual display relatively easily from the screen data created so far in order to determine the display operation and operation reception operation of the programmable display. In addition, the system can generate screen data with a small amount of data, and is used to control the device 2a of the target system 2 (for example, a belt conveyor type automatic assembly machine) as shown in FIG. ing.

  Below, before describing the configuration for generating new screen data, the schematic configuration and operation of the entire control system will be described.

  That is, in the control system 1, the PLC 11 as a control device for controlling the device 2a and, in many cases, arranged in the vicinity of the control target, and also displays the state of the device 2a as the HMI of the control system 1, And a programmable display (control display device) 12 for receiving an operation on the device 2a by the operator. In the control system 1 according to the present embodiment, the programmable displays 12 are connected to each other by a LAN (Local Area Network) 13 such as Ethernet (registered trademark). Further, in many cases, a control host computer (screen data conversion device) 14 that manages the entire control system 1 is connected to the LAN 13 from a location farther than the programmable display 12.

  Moreover, each said programmable display 12 is connected with PLC11 corresponding to each via communication paths, such as a serial cable. In FIG. 2, for convenience of explanation, two programmable displays 12 are connected to the LAN 13, one PLC 11 is connected to each programmable display 12, and one device 2 a is connected to each PLC 11. However, as a matter of course, the number of connected units can be arbitrarily set.

  In addition, the device may be the device 2a itself, for example, as long as the device can be specified by the device address, and the state can be acquired or controlled (changed), for example, the PLC 11 or the programmable display 12 An area of a storage device provided in the control system 1 may be shown.

  Here, in the said control system 1, since it is a structure essential for the control system 1, and since it operate | moves as HMI, it is comprised so that the programmable display 12 with sufficient computing power may process most communication. . Furthermore, each programmable display 12 converts a dedicated protocol unique to the model of the PLC 11 connected to itself and a common protocol in the LAN 13, and the other programmable display 12 and the control host computer 14, Relay communication with the PLC 11. For protocol conversion between the common protocol and the dedicated protocol, conversion between a predetermined common command so that the same code is assigned to the same instruction and a command unique to the PLC 11 corresponding to the common command is performed. And conversion of data and address expression methods.

  Thereby, the programmable display 12 and the control host computer 14 can communicate with each other via the LAN 13 regardless of the type of the PLC 11 connected to the other programmable display 12. As a result, the control system 1 in which different types of PLCs 11 are mixed can be realized relatively easily.

  The programmable display 12 specifies an operation for displaying the device state on the screen and an operation for controlling the device state in accordance with an operation on the screen based on screen data described later. The PLC / IF unit 21 that communicates with the PLC 11, the LAN / IF unit 22 for connecting to the LAN 13, a display (display means) 23 composed of, for example, a liquid crystal display device, and the screen of the display 23. Touch screen (operation means) 24, an HMI processing section (control means) 25 for controlling each of the members 21 to 24, and a storage device (for example, a memory) referred to by the HMI processing section 25, and the screen data And a storage unit 26 for storing a character string table to be described later.

  The screen data is configured by combining a tag (data unit) indicating a correspondence relationship between an area on the screen and a device corresponding to display or input in the area. In the present embodiment, the HMI processing unit 25 can switch and display a plurality of unit screens, and the tag specifies the file number indicating the unit screen for which the tag is valid and the operation content to be executed on the unit screen. Event name and reference information referenced for each event.

  For example, when the tag is a display tag that displays a part graphic corresponding to a predetermined device state in a predetermined screen area (display coordinate range), the reference information includes a display coordinate range, an address for specifying a device, and the like. For example, when the part figure is a switch, a file number referred to at the time of display such as a figure file indicating ON and a figure file indicating OFF is included. Further, when the tag is an input tag, reference information includes an effective input coordinate range and an address of a device to which an input result is written.

  In addition, the storage unit 26 stores the state of the device accessed by the programmable display 12 that operates based on the screen data in association with each device. In this embodiment, an expression method for storing the device status (for example, word length, presence / absence of code, BCD / binary notation, etc.) regardless of the model of the device 2a corresponding to the device address. Are unified in a predetermined expression method, and when the device address corresponds to the actual device 2a, the storage unit 26 also stores the expression method in the actual model. In this case, when the HMI processing unit 25 acquires or controls the state of the device 2 a via the PLC / IF unit 21, the HMI processing unit 25 converts the representation method to unify the representation method at the time of storage.

  On the other hand, the HMI processing unit 25 extracts a display tag whose base screen file number is the currently displayed base screen from the screen data stored in the storage unit 26 at predetermined time intervals. Further, the HMI processing unit 25 reads the state of the device corresponding to the tag from the storage unit 26 and displays a part graphic corresponding to the state on the display 23. Here, when the device accessed by the programmable display 12 that operates based on the screen data corresponds to the device 2a controlled by the PLC 11 connected to the PLC / IF unit 21, the HMI processing unit 25 The state of the device 2a is acquired by communication with the PLC 11 by the PLC / IF unit 21, and the state of each device stored in the storage unit 26 is updated according to the acquired state. Thereby, the state of the device 2a is displayed on the display 23.

  When the device address indicates the device 2 a controlled by the PLC 11 connected to the other programmable display 12, the HMI processing unit 25 includes the LAN / IF unit 22, the LAN 13, and the other programmable display 12. The state of the device is acquired by communicating with the PLC 11 via, and the storage unit 26 is updated accordingly.

  When receiving an operator input operation such as a push operation on the touch panel 24, the HMI processing unit 25 searches the screen data for an input tag corresponding to the currently displayed base screen and matching the input operation. At the same time, the device state corresponding to the tag is updated among the device states stored in the storage unit 26 according to the input result. Further, the HMI processing unit 25 communicates with the PLC 11 and the programmable display 12 in substantially the same manner as in the case of acquiring the state of the device 2a, and according to the state of the device stored in the storage unit 26, the device 2a Control the state of Here, even after the input operation, the HMI processing unit 25 displays the state of the device 2a on the screen, so that the operation result is reflected on the screen display.

  As a result, the programmable display 12 can display the state of the device 2a on the screen based on the instruction of the screen data, and can control the state of the device 2a according to the operation on the screen.

  The HMI processing unit 25 receives, for example, a control instruction from the device connected to the LAN 13 such as another programmable display 12 or the control host computer 14 to the device 2a of the PLC 11 connected to itself. On the contrary, when the status of the device 2a to be reported to the device is received from its own PLC 11, it is possible to relay between the communication on the LAN 13 and the communication with the PLC 11 by the protocol conversion described above.

  On the other hand, the control host computer 14 is connected to the LAN 13 by the HMI processing unit 41 that performs monitoring control of the control system 1, the LAN / IF unit 42 that communicates with the above-described common protocol, the LAN / IF unit 42, and the LAN 13. And a server unit 43 that responds to a request from the HMI processing unit 41 and the like, and can display or control the state of the target system 2, the PLC 11, or the programmable display 12.

  The control host computer 14 is provided with a drawing processing unit 44 for creating screen data of the programmable display 12 and a storage unit (storage device) 45 for storing the created screen data. The unit 44 can create (correct) the screen data that defines the display / control operation of each programmable display 12, and then distribute it to each programmable display 12 via the server unit 43, the LAN / IF unit 42, and the LAN 13. .

  Here, the screen data is configured by combining a tag indicating a correspondence relationship between an area on the screen and an address that can identify a device corresponding to display or input in the area. For example, a palette of tags is displayed and the user is prompted to select a tag in the palette and place the desired tag on the screen. In addition, the drawing processing unit 44 displays the arranged tags at the designated coordinates, and adjusts the coordinates of the tags according to the user's operation such as drag and drop. In addition, the drawing processing unit 44 prompts the user to input an address related to the tag. As a result, the user can create screen data simply by operating the drawing processing unit 44 to place tags at desired positions on the screen and associating each tag with a device address.

  Therefore, the display and operation of each programmable display 12 can be determined (changed) more easily than when the display program of the programmable display 12 is modified, and the user of the control system 1 (the user of the control host computer 14) can The actual condition of the target system 2, the proficiency level of the operator of the programmable display 12, or the user's preference can be adjusted.

  By the way, although the tag for displaying the state of the device 2a has been described above, there are display elements including a character string (including the character string itself) as display elements constituting the screen. A tag (character string related tag) for displaying a display element including these character strings can be included. The tag includes, for example, a character string tag for displaying a character string that exists independently of other display elements, and a nameplate for displaying characters (nameplate character string) displayed in relation to the component. Examples include a character string tag and a message display tag for displaying a message display for notifying a message. The character string related tag according to the present embodiment includes an alarm message tag for displaying an alarm message (flow display), an alarm summary tag for displaying a character string indicating an outline of the alarm, or An alarm history tag for displaying an alarm history of the data of the device 2a is included. The data may be bit data or word data. Further, the character string related tag includes a text screen tag for displaying a character string as a text screen.

  As an example, a description will be given using a character string tag as an example. As shown in FIG. 3, as reference information R, information P indicating a screen area and a character string ST to be displayed expressed in a character code are included. ing. In FIG. 3, for convenience of explanation, the character codes are displayed by the character strings indicated by them (in the example shown, the character string “alarm”). Further, the event name N of the tag is set to a value indicating that it is a character string tag. On the other hand, when displaying the character string tag, the HMI processing unit 25 of the programmable display 12 includes a character code included in the character string tag as reference information R to the screen area indicated by the character string tag. The character string ST is displayed.

  On the other hand, in recent years, there has been a demand for a programmable display 12 that can switch and display a plurality of languages in accordance with the language used by the operator. The HMI processing unit 25 according to the present embodiment replaces the character string itself, A character string-related tag including a reference to a character string stored separately from the screen data can be processed.

  In the present embodiment, the character string to be referred to is stored as the character string table TT in the storage unit 26 of the programmable display 12 or the storage unit 45 of the control host computer 14, and the reference to the character string is as follows: This is the position (index) in the table of the character string. In the following, instead of the character string itself, a tag including a reference to the character string is referred to as an indexed tag or an indexed tag, and the character string displayed by the tag is an indexed character. This is called a column. On the other hand, a tag including the character string itself is referred to as an unindexed tag or a non-indexed tag.

  For example, as shown in FIG. 4, in the character string table TT, among the character strings displayed by the screen data D, the character strings displayed by the indexed character string related tags are stored as records. Has been. Each record is stored so that it can be specified by a position (index) in the character string table TT. For example, in FIG. 4, the record R1 (first record) with index 1 is an “alarm”. Similar to FIG. 3, in FIG. 4, the character codes stored in each record are displayed by the character string indicated by them.

  On the other hand, as an indexed character string related tag (indexed character string related tag), the case of a character string tag will be described as an example. In the character string tag shown in FIG. In contrast, as shown in FIG. 5, the indexed character string tag (indexed character string tag) includes an index I as reference information R. In addition, the drawing processing unit 44 according to the present embodiment receives an instruction to generate an indexed character string-related tag, and also includes a character string table TT that includes the indexed character string, and a screen that includes a tag that refers to the character string Data D can be generated. In the present embodiment, the event name N of the indexed character string tag is set to a value ("i") different from that of the non-indexed character string tag (non-indexed character string tag) and is different. Recognized as a type tag.

  Further, for example, a member that refers to the character string table TT, such as the HMI processing unit 25, extracts the index I from the indexed character string tag, and is designated by the index I from the records included in the character string table TT. Read the character string. Thereby, although the character code itself is not included in the indexed character string tag, the member can acquire the character code of the indexed character string without any trouble. For example, in the example of FIG. 5, since the index I is 1, the character string (“alarm” in the case of FIG. 4) of the first record R1 in the character string table TT is read.

  Thus, the indexed character strings are stored in a character string table TT different from the screen data D. Therefore, for example, a character string table TT having a different content from the past is stored in the storage unit 26, or, for example, a plurality of character string tables TT are stored in the storage unit 26 in advance, for example, an operator instruction or the like The programmable display 12 displays the screen data D without changing the character string table TT that is referred to by the HMI processing unit 25 or changing the character string table TT. Character strings can be switched at once.

  For example, the character string table TT shown in FIG. 6 stores records of different languages (in this example, English) with the same meaning as the records of FIG. As a result, the programmable display 12 can switch from the Japanese display to the English display without changing the screen data D by switching the contents of the character string table referred to during display from FIG. 4 to FIG. 6.

  Therefore, by generating screen data using an indexed character string-related tag, the programmable display 12 can be easily adapted to a plurality of languages as compared to the case of using a non-indexed character string-related tag. .

  Further, as shown in FIG. 3, the control host computer 14 according to the present embodiment generates a new character string table TT by referring to the existing character string table TT, as well as existing screen data D. Is provided with a conversion processing unit 51 that converts the non-indexed character string-related tag included in the information into an indexed character string-related tag and generates new screen data D.

  More specifically, as shown in FIG. 1, the conversion processing unit 51 includes an extraction processing unit (extraction means) 61 that extracts non-indexed character string-related tags from existing screen data D, and each extracted A character string is extracted from the character string-related tag, and a search processing unit 62 that searches the character string table TT for a record that matches the character string. If not found, the extracted character string record is a character string. The record addition processing unit (character string table updating means) 63 to be added to the table TT and the character string related tags extracted by the extraction processing unit 61 are converted into indexed character string related tags, and the converted character string related tags As a reference information R, a tag conversion processing unit (decodes a record found by the search processing unit 62 or an index of a record added by the record addition processing unit 63). And a motor unit converting means) 64. The tag conversion processing unit 64 does not change reference information other than the character string (for example, information on the screen area) when converting the non-indexed character string-related tag, and has the same value as the reference information before conversion. Set to. In addition, as described above, in this embodiment, since the non-indexed character string tag and the indexed character string tag have event names having different values, the tag conversion processing unit 64 changes the event name. Yes.

  In the above configuration, in step 1 shown in FIG. 7 (hereinafter abbreviated as S1), the extraction processing unit 61 of the conversion processing unit 51 uses the screen data D to be converted stored in the storage unit 45 as follows. Extract all non-indexed string related tags.

  Furthermore, when there is an unprocessed non-indexed character string related tag (in S2, YES), in S3, the search processing unit 62 extracts a character string from the character string related tag, and the character string table A record that matches the character string is searched from TT.

  If no matching record is found (NO in S4), the record addition processing unit 63 adds the record of the character string to the character string table TT in S5, and the tag conversion processing unit 64 performs S6. The character string related tag to be converted is converted into a character string related tag including the index of the record. On the other hand, if a matching record is found (YES in S4), the tag conversion processing unit 64 records the character string related tag to be converted in S3 in S7. Convert to a string-related tag containing the index of.

  For example, in the state where the record shown in FIG. 5 is stored in the character string table TT, as shown in FIG. 3, when processing a character string tag including a character string “Alarm”, the character string is a character string. The index of each record in the column table TT matches the record R1 with 1. Therefore, the tag conversion processing unit 64 converts the character string tag into a character string tag having an index I of 1, as shown in FIG.

  On the other hand, when a character string tag including a character string “date” is processed in this state, the character string does not match any record in the character string table TT. Accordingly, the record addition processing unit 63 newly adds a record R2 whose content is “date” as shown in FIG. 8 to the character string table TT, and as shown in FIG. The index I is converted to a character string tag having a value of 2.

  The above steps (S3 to S7) are repeated until there is no unprocessed character string related tag (until NO in S2). Thereby, the conversion process part 51 can produce | generate the new screen data D by which all the character string related tags are indexed from the said existing screen data D. FIG.

  In the above configuration, the conversion processing unit 51 generates a new character string table TT by referring to the existing character string table TT, and also displays the non-indexed character string related tags included in the existing screen data D. , Converted into an indexed character string-related tag to generate new screen data D.

  Therefore, it is possible to generate screen data with less effort compared to the case where the user operates the drawing processing unit 44 to newly create screen data that does not include a non-indexed character string-related tag.

  Further, in the above configuration, the search processing unit 62 converts the character string related tags for displaying the same character strings to character string related tags having the same index. Therefore, an area for storing the substance of the character string can be shared among a plurality of character string related tags, and the data amount of the screen data D and the character string table TT can be reduced.

  In the above description, the case of changing the event name (tag type) at the time of indexing was explained using the character string tag as an example. However, in the following, the alarm message tag is taken as an example and non-indexed The case where the event name of the tag and the event name of the indexed tag are the same and information indicating whether or not indexed is included in a part of the reference information R will be described as an example.

  For example, as shown in FIGS. 10 and 11, regardless of whether or not a character string is indexed, the alarm message tag is an event name indicating that it is an alarm message tag (in the example shown, 10h ) N and reference information. In addition, in the reference information, for example, an alarm has occurred such as the address of a device to be monitored and a threshold value (in the example of the figure, the maximum value and the minimum value) for determining the device state as abnormal. Information A indicating whether or not. Thereby, the programmable display device 12 can identify the device to be monitored by referring to the alarm message tag, monitor the state of the device, and display the device indicated by the alarm message tag. It can be determined whether or not an abnormality indicated by the alarm message tag has occurred.

  Furthermore, in the case of a non-indexed alarm message tag (non-indexed alarm message tag), as shown in FIG. 10, a character string ST displayed as a message is included as a character code. Thereby, the HMI processing unit 25 of the programmable display device 12 can display the character string ST included in the alarm message tag when an abnormality occurs in the device indicated by the alarm message tag.

  On the other hand, in the case of an indexed alarm message tag (indexed alarm message tag), as shown in FIG. 11, instead of the character string ST shown in FIG. Index I is included. Thereby, when an abnormality occurs in the device indicated by the alarm message tag, the HMI processing unit 25 of the programmable display 12 reads the index I record included in the alarm message tag from the character string table TT. The character string of the record can be displayed. Although the non-indexed alarm message tag does not include an identifier indicating that it is not an index, the identifier II is set to a value that cannot be a character code, for example. Therefore, by determining whether the value of the area storing the identifier II or the character string ST in the alarm message tag is the identifier II, the identifier II is included in the tag without any trouble. It can be determined whether or not it is indexed.

  When processing the alarm message tag, the extraction processing unit 61 of the conversion processing unit 51 extracts the alarm message tag that does not include the identifier II from the screen data D, thereby removing the non-indexed alarm message tag. Extract. On the other hand, the tag conversion processing unit 64 changes the character string ST of the alarm message tag to the identifier II and the index I indicating a record having the same content as the character string ST, thereby making a non-indexed alarm. Index message tags.

  Thereby, even when the conversion processing unit 51 processes a tag including information indicating whether or not it is indexed in a part of the reference information R, like an alarm message tag, The tag can be indexed without any trouble.

  In the above description, the case where the character string does not include a line feed and is displayed in a batch has been described as an example. However, the present invention is not limited to this, and the character string may include a line feed. Of these, a portion corresponding to the state of the device may be displayed.

  In the following, as an example of another character string-related tag, a text screen tag for displaying a character string composed of a plurality of lines on the screen or displaying a line corresponding to the state of the device among the plurality of lines will be described. . In the text screen tag according to the present embodiment, the event name is constant regardless of the presence or absence of indexing.

  Specifically, as shown in FIG. 12, an unindexed text screen tag (non-indexed text screen tag) is an event name N indicating that it is a text screen tag and screen area information P. In addition, a character string ST consisting of a plurality of lines is included. Furthermore, the text screen tag shown in FIG. 12 not only displays a plurality of lines, but also displays a line corresponding to a predetermined device state among lines included in the character string ST. And a device address DA for specifying the device. Note that when displaying the text screen tag, the HMI processing unit 25 of the programmable display 12 selects a line corresponding to the state of the device 2a specified by the device address DA among the lines included in the character string ST. Is displayed.

  On the other hand, as shown in FIG. 13, the indexed text screen tag (indexed text screen tag) includes the same identifier II and index I as in FIG. 11 instead of the character string ST shown in FIG. It is. In the character string table TT, the record indicated by the index I includes a character string consisting of a plurality of lines. Note that when displaying the text screen tag, the HMI processing unit 25 of the programmable display 12 determines that the index II is indexed, and indicates the index I of the records in the character string table TT. Identify the record. Further, of the lines included in the character string ST of the record, a line corresponding to the state of the device 2a specified by the device address DA is displayed.

  When processing the text screen tag, the extraction processing unit 61 of the conversion processing unit 51 extracts the text screen tag that does not include the identifier II from the screen data D, thereby removing the non-indexed text screen tag. Extract. Further, as shown in FIG. 14, the character string table TT is configured such that a character string consisting of a plurality of lines can be included in one record. 14 illustrates a case where a character string consisting of a plurality of lines is included in the record R3 and the record R4 is a character string “time” for convenience of explanation. Further, the search processing unit 62 can compare character strings composed of a plurality of lines and determine whether or not the extracted character string matches any of the records in the character string table TT. The record addition processing unit 63 can add the extracted character string as a record of the character string table TT when the search processing unit 62 determines that none of the record addition processing units match. On the other hand, the tag conversion processing unit 64 changes the character string ST of the text screen tag to the identifier II and the index I indicating a record having the same content as the character string ST, thereby making the non-indexed text. Index screen tags. When indexing, the tag conversion processing unit 64 holds other information included in the text screen tag, such as a device address, as the contents before indexing.

  As a result, the conversion processing unit 51 can perform indexing without any trouble even when the character string is composed of a plurality of lines, such as a text screen tag.

  By the way, in addition to the above configuration, the conversion processing unit 51 according to the present embodiment, before outputting the converted screen data D and the updated character string table TT, as shown in FIG. A rearrangement processing unit (rearrangement unit) 65 that rearranges the records (character strings) of the column table TT and updates the index of the tag included in the screen data in accordance with the rearrangement result.

  As an example, a case where the records are rearranged in the order of the character codes of the character string will be described as an example. The rearrangement processing unit 65 is configured when the records shown in FIG. 8 are stored in the character string table TT. As shown in FIG. 15, the records in the character string table TT are rearranged in the order of the respective character codes, and the character string table TT after the rearrangement is stored in the storage unit 45. Note that FIG. 15 illustrates an example of rearrangement in descending order, and the order of the records R1 and R2 in the character string table TT in FIG. 8 is switched. The rearrangement processing unit 65 changes the index of each indexed character string-related tag included in the screen data D according to the result of rearrangement, and stores the screen data D including the changed indexed character string-related tag. 45. In this example, since the records R1 and R2 are interchanged, the reordering processing unit 65 changes the index of the indexed character string related tag whose index was 1 before the change to 2, and the index before the change is the index. The index of the indexed character string relation tag that was 2, is changed to 1. Therefore, the programmable display 12 that refers to the screen data D and the character string table TT after the rearrangement refers to the screen data D and the character string table TT before the rearrangement although the order of the records is rearranged. The same character string can be displayed.

  Thus, the conversion processing unit 51 according to the present embodiment is provided with the rearrangement processing unit 65, and can output the character string table TT and the screen data D after the rearrangement. Therefore, even if a device capable of displaying the contents of the character string table TT (for example, a screen data and character string table editing device) does not have a function for rearranging character strings in the character string table, By displaying the screen data D and the character string table output from the conversion processing unit 51, the apparatus can present the rearranged character string table to the user, and can present related character strings collectively.

  Here, if the order in which the records are rearranged is an order that can be easily understood by the user who refers to the character string table TT, in addition to the character code, the order of the identification numbers assigned to the tags in order to identify the tags, etc. Can be set in various orders. However, character strings starting from the same word are often translated into translations that are the same or related to each other. Therefore, it is particularly preferable that the records in the character string table TT can be presented to the user in the order in which they are easily translated by rearranging the characters in the order of the character codes as in the example described above.

  By the way, the character string table TT after indexing the screen data D is a character string in the language displayed by the screen data D before indexing. Therefore, simply indexing the character string table TT in another language. Cannot be generated. Therefore, in order to make the programmable display 12 multilingual, it is necessary to translate a character string included in the character string table TT and create a character string table TT for a required language.

  However, since the user who created the screen data D in the original language or the user of the conversion processing unit 51 that received the screen data D is not necessarily familiar with these other languages, I often request translations and checking the translated text.

  On the other hand, the conversion processing unit 51 according to the present embodiment further includes a mailer control unit (e-mail generation means) 66 for controlling the mailer 46 provided in the control host computer 14 as shown in FIG. The mailer control unit 66 can control the mailer 46 to create an e-mail with the character string table TT stored in the storage unit 45 and, if necessary, the screen data D as an attached file. In addition, the mailer control unit 66 has a predetermined format in which the character string table TT or the screen data D stored in the storage unit 45 can be processed at the request destination as necessary before being attached as an attached file. It can be changed to

  Therefore, in the following case, that is, after the user of the conversion processing unit 51 changes the character string table TT stored in the storage unit 45 to a format that can be processed at the request destination as necessary, the character string table TT is Compared to the case where an attached e-mail is created and sent to the request destination, it is possible to reduce the trouble of requesting translation to others.

  In this embodiment, since the transmission destination and the content of the text are often changed, the mailer control unit 66 of the conversion processing unit 51 instructs the mailer 46 only to attach the attached file, and the transmission destination and the text of the text are changed. If setting or transmission of an e-mail is not instructed, but the e-mail transmission destination is fixed, the mailer control unit 66 generates an e-mail with the transmission destination address stored in advance as the transmission destination. As such, the mailer 46 may be controlled. Further, if the body of the e-mail to be transmitted together with the attached file is fixed, the mailer 46 may be controlled so as to generate an e-mail using the preset body as the body of the e-mail. Furthermore, when the text and the transmission destination are fixed and the electronic mail may be generated and transmitted, the mailer control unit 66 may control the mailer 46 to automatically transmit the electronic mail.

  In addition, the conversion processing unit 51 according to the present embodiment, for example, instructs translation to a translation program that translates in a stand-alone manner or instructs the translation server to translate via the Internet. The translation processing part 67 which translates each character string contained in is provided. Thereby, even when the screen data D before indexing includes only a single language character string and the record addition processing unit 63 can generate only the character string table TT for the language, the translation is performed. The processing unit 67 translates the character string of the character string table TT for the language, so that the character string table TT for another language can be generated.

  Even in this case, it is desirable to ask a person who is proficient in the other language, such as a person whose native language is the language, to confirm whether or not the translation is correct. Therefore, the mailer control unit 66 controls the mailer 46 to generate an e-mail with the translated character string table TT as an attached file, thereby reducing the time and effort at the time of request.

  In the above description, the case where the device is specified by the device address has been described as an example. However, the present invention is not limited to this. If the device can be specified, the device may be specified by other information such as a variable. . The variable is information for specifying each device, and is associated with a name and a device address different from the device address. On the other hand, when the device is specified by the variable or the name of the variable, the HMI processing unit 25 of the programmable display 12 accesses the device address associated with them, as in the case specified by the device address, The state of the device can be acquired.

  In the above description, the case where each information is associated with a tag has been described as an example. However, the present invention is not limited to this. For example, if the same information is associated, the information is associated as an attribute of an object. Then, these pieces of information may be associated with other data as a unit.

  The members 21, 22, 25, and 26 and the members 41 to 67 are such that a calculation unit such as a CPU executes a program stored in a storage unit such as a ROM or a RAM, and a touch panel, a liquid crystal display device, or the like. Is a functional block realized by controlling a communication circuit such as an input / output means or an interface circuit. Of these members, the members (26, 45) for storing data may be the storage device itself. Therefore, the computer having these means reads the recording medium (for example, CD-ROM) on which the program is recorded and executes the program, and the programmable display 12 and the control host computer according to the present embodiment. 14 can be realized.

  Also, for example, if a program for downloading a program via a serial cable, LAN 13, or other communication path is installed in the computer in advance, the program is distributed to the computer via the communication path. You can also

  The screen data conversion apparatus according to the present invention, and its program and recording medium can be used to generate non-indexed tags from screen data including non-indexed tags without redesigning the screen so as not to include non-indexed tags. Since it can be converted into screen data not included, screen data that can be displayed in a multilingual display can be generated relatively easily, and can be suitably used for multilingual control display devices.
