In addition, the text program editing unit 11 further includes a use device extraction unit 13, a use device attachment information extraction unit 14, a use device display position extraction unit 15, and the like. , The use device attachment information omission unit 16 and the text attachment information display unit 19 are provided.

The using device extraction unit 13 refers to the text program display unit 18 or the text program storage file 8 to extract a device described in the text program. The extracted device is input to the use device attachment information extraction unit 14 and the use device display position extraction unit 15.

The used device accessory information extracting unit 14 refers to the device accessory information setting unit 12 or the device accessory information preservation file 9 to retrieve the device comment set for the device extracted by the use device extracting unit 13. Extract.

The use device display position extraction unit 15 refers to the text program display unit 18 and extracts the display position of the device extracted by the use device extraction unit 13.

The use device attachment information omission unit 16 calculates the number of characters that can be displayed as the device comment based on the next device display position in the same row as the device display position extracted by the use device display position extraction unit 15. do. The use device attachment information omission unit 16 compares the calculated displayable number of characters with the number of characters of the device comment extracted by the use device attachment information extraction unit 14. As a result of the comparison, if the number of characters of the extracted device comment is larger than the number of characters that can be displayed, the use device accessory information omission section 16 selects a part of the device comment so that the number of characters of the device comment is within the range of the number of characters that can be displayed. Omit processing (hereinafter, referred to as omission processing) is performed. On the other hand, if the number of characters of the extracted device comment is less than or equal to the number of characters that can be displayed, the omission process is not performed and is left as it is.

The text appended information display unit 19 receives a character string of a device comment and information on its display position from the used device appended information omission section 16. The text appended information display unit 19 displays the character string of the device comment between the lines of the text program displayed by the text program display unit 18 based on the display position.

The text appended information display unit 19 will be described in detail with reference to FIG. 4. It is assumed that the text program display unit 18 displays the text program on the display unit 3, as shown in Fig. 4A. In this text program, for example, "D124" and "D123" in the third line are devices. At this time, as shown in Fig. 4 (b), the text appended information display unit 19 includes the lines (i.e., the third line) of the text program in which these devices are displayed, and the lines immediately after that (i.e., the fourth line). The text appended information display area 30 is provided between the lines between and, and the device comments such as "operation result" and "storage of the measurement result" are displayed there. In addition, the text accompanying information display unit 19 is based on the display position of the display position of each device and the display position of the device comment corresponding to the device based on the information of the display position from the use device attached information omitting unit 16. The display position of the device comment is set so that the head is arranged in the longitudinal direction. In the example of FIG. 4 (b), the display position of the character "D" at the head of the device "D124" and the display position of the character "연" at the head of the device comment "computation result" corresponding thereto are arranged in the longitudinal direction. It is. Similarly, the display position of the character "D" at the head of the device "D123" and the display position of the character "system" at the head of the device comment "Storage of the measurement result" corresponding thereto are arranged in the longitudinal direction.

In addition, although FIG. 4 (b) showed the example which displays a device comment in the line immediately after the line in which the device is displayed, it is not limited to that case, but the device comment is just before the line in which the device is displayed. It may be displayed on the line of.

FIG. 3 shows a processing flowchart of the program creation support device 1 according to the first embodiment of the present invention. First, in step S1, the text program editing unit 11 determines whether or not an instruction to display device comments for the entire text program has been input by the program author. When the instruction is input, the process proceeds to step S3, and the processes of steps S3 to S11 are performed for every line in every line included in the text program. On the other hand, when the said instruction is not received, it progresses to step S2.

In step S2, the text program editing unit 11 determines whether or not an instruction for displaying a device comment for one line included in the text program has been input by the program creator. If the instruction is not received, the flow returns to step S1. On the other hand, if the said instruction | command is received, the process of step S3-S11 is performed about the row.

In step S3, the use device extraction unit 13 refers to the text program display unit 18 or the text program storage file 8 to extract the device described in the text program.

Next, in step S4, the used device accessory information extracting unit 14 is set for the device extracted in step S3 with reference to the device accessory information setting unit 12 or the device accessory information storing file 9. Extract the device comment.

Next, in step S5, the use device display position extraction unit 15 refers to the text program display unit 18, and the device extracted in step S3 is located in the text program displayed by the text program display unit 18. It detects whether it is displayed and extracts the display position.

Next, in step S6, the use device attachment information omission unit 16 determines whether there is a next device displayed in the same row as the row in which the device to be extracted in step S3 is displayed. In other words, it is determined whether there are a plurality of devices in one row in which the device is extracted in step S3. As a result of the determination, if there is a next device, the process proceeds to step S7. If there is no next device, the process proceeds to step S9.

In step S7, the used device attachment information omission unit 16 obtains a difference between the display position of the device extracted earlier and the display position of the next extracted device, and calculates the difference as a device comment for the previously extracted device. Set as the number of characters that can be displayed.

Next, in step S8, the use device attachment information omission unit 16 compares the number of displayable characters obtained in step S7 with the number of characters of the device comment of the device previously extracted. As a result of the comparison, if the number of characters in the device comment is less than or equal to the number of characters that can be displayed, the flow proceeds to step S9. If the number of characters in the device comment exceeds the number of characters that can be displayed, the flow proceeds to step S10.

In step S9, since the device comment does not need to be omitted because the number of characters in the device comment is less than or equal to the number of characters that can be displayed, the use device attachment information omission unit 16 does not perform the omission process, and proceeds to step S11. .

In step S10, since the number of characters in the device comment exceeds the number of characters that can be displayed, the use device attachment information omitting unit 16 selects a portion of the device comment so that the number of characters in the device comment is within the range of characters that can be displayed. The abbreviation process to abbreviate | omit is performed, and then, it progresses to step S11.

As to the method of setting the number of characters that can be displayed, various methods can be considered in addition to the above methods. For example, since the number of characters of the device is approximately four half-width characters, there is a method in which the number of displayable characters is fixed length, such as four half-width characters. Alternatively, a device comment may be displayed within the range of the number of characters of the device, with the number of characters of the device being the number of characters that can be displayed in the device comment. However, as described above, the method of setting the number of characters that can be displayed as the number of characters between the display position of the previous device to the display position of the next device on the same line is the most characters. Since it is a method which becomes possible to display, this method shall be used in this embodiment.

In addition, regarding the omission process of the device comment to the number of characters which can be displayed in step S10, the method of deleting the characters after that and leaving only the number of characters that can be displayed from the head of the characters of the device comment, If it is set to kanji and hiragana, there may be mentioned a method of deleting hiragana by leaving only kanji. In the present embodiment, any method may be used, but for the sake of simplicity, the following description will be given by taking a method of deleting the characters afterwards, leaving only the number of characters that can be displayed from the beginning. do.

In step S11, the text accompanying information display unit 19 receives the device comment obtained in step S9 or step S10 and the display position information from the used device attached information omitting unit 16, and transmits the information to the text program display unit 18. The device comments obtained in step S9 or step S10 are displayed between the lines of the text program displayed by the step.

Further, the text accompanying information display unit 19 displays the device comment when the program creator receives an instruction to display the device comment, and displays the device comment when the program creator has received the instruction to hide the device comment. Switch to The default value is not displayed.

4 shows an example of the operation of the text program editing unit 11 of the program creation support device 1 according to the first embodiment of the present invention. Hereinafter, it demonstrates concretely accordingly.

First, as shown in Fig. 4A, the text program display section 18 of the text program editing section 11 displays the text program and the program comment described by the program creator.

(Step S1 of FIG. 3)

In contrast, the program author performs an operation of displaying a device comment. As a specific operation method, it is conceivable to give an instruction to display the device comment from the operation menu of the program creation support device 1, in which case, the process of displaying the device comment for the entire text program, i.e., all lines of the program text. Will be done.

(Step S2 of FIG. 3)

As another method, as shown in Fig. 4 (a), since the line number is displayed at the head of each line of the text program displayed by the text program display unit 18, the program creator is responsible for the line number. The number of lines for which device comments are to be displayed is designated by clicking on a mouse or the like. In this case, only one line of the designated text program is processed to display the device comment. Hereinafter, a description will be given of a case in which the program creator has an operation for displaying a device comment on the third line of the text program.

(Step S3 of FIG. 3)

The using device extraction unit 13 refers to the text program display unit 18 or the text program storage file 8 to extract the device described in the third line of the text program. Here, "D124" and "D123" are extracted as a device.

(Step S4 of FIG. 3)

Next, the use device attachment information extraction unit 14 refers to the device attachment information setting unit 12 or the device attachment information storage file 9, and the two devices “extracted by the use device extraction unit 13” The device comments set for each of "D124" and "D123" are extracted. Here, as shown in FIG.4 (d), device comment "storing of a calculation result" is extracted with respect to device "D124", and device comment "storing of a measurement result" is extracted with respect to device "D123".

(Step S5 of FIG. 3)

In addition, two device "D124" and "D123" which the use device display position extraction part 15 extracted by the use device extraction part 13 refer to the text program display part 18, and the text program display part ( Where in the text program displayed by 18) is displayed, the display position is extracted. Here, it is extracted that the display position of "D124" is the sixth character at half-width counting from the beginning of the line, and that the display position of "D123" is the 16th character at half-width counting from the beginning of the line.

(Step S6 of FIG. 3)

In this case, since two devices are extracted in one line, the determination of step S8 regarding the limitation of the number of display characters is performed with respect to the device comment "storing of the operation result" set for the previously extracted device "D124". If it is necessary and the number of characters which can be displayed is exceeded, the omission process of step S10 is performed.

(Step S7 of FIG. 3)

The use device attachment information omission section 16 first displays the display of each device comment of "D124" and "D123" from the display position of the device "D124" and the display position of the next device "D123" in the same line. Calculate the number of possible characters. Since there is the next device "D123" about the device "D124", 6 is subtracted from 16 which is each display position, and it calculates that the difference is 10. This 10 may be the number of characters that can be displayed, but preferably, one half-width character is secured between the last character of the device comment of the previous device and the first character of the device comment of the next device. There is a need. Therefore, 10 to 1 are further subtracted to calculate the number of characters that can be displayed as nine characters at half-width. In addition, about "D123", since there is no next device, there is no limit to the number of displayable characters.

(Steps S8 to S10 in Fig. 3)

Next, if the number of characters in the device comment is compared with the number of characters that can be displayed, and if the number of characters in the device comment is larger, an omission process of omitting a part of the device comment to be within the range of the number of characters that can be displayed is performed. Here, about device "D124", since device comment "storing of calculation result" is seven characters (14 characters in half size conversion) at full size, this is omitted within nine characters (cutting off part in full size conversion, four characters) in half size do. As the simplest method, only four full-width characters are left from the beginning, and subsequent portions thereof are deleted, and the operation result is set. And since there is no restriction | limiting in the number of characters which can be displayed about "D123", it becomes "storage of a measurement result" as it is.

(Step S11 of FIG. 3)

Finally, the text program editing unit 11 is shown in FIG. 4 (b) immediately after the third line of the text program displayed by the text program information display unit 18 by the text attachment information display unit 19. The text appended information display area 30 is provided, and with respect to the device "D124", the sixth character is set as the display position at half-width from the beginning of the line, and the device comment "computation result" is displayed. This is abbreviate | omitted and abbreviate | omitted the "storing of an operation result" of an original device comment. Regarding the device "D123", the device comment "Storage of the measurement result" is displayed with the 16th character as a display position half-width from the head of a line. As for the device comment "storing of the measurement result", since the elimination process is not necessary, it is displayed as the original device comment. In addition, although the text attached information display area | region 30 by the text attached information display part 19 was shown about the example provided immediately after the said line, it is not limited to that case, Even if it provided immediately before the corresponding line, good.

In addition, in order to distinguish clearly whether it is the display by the text program display part 18 or the display by the text attached information display part 19, for example, in FIG.4 (b), the text program display part ( Regarding the display by 18), the line numbers (1, 2, 3, ...) are displayed at the head of each line, and the display by the text appended information display unit 19 is displayed at the head of the line. "D" is displayed to distinguish them.

In the present embodiment, as shown in Fig. 4 (b), in the display of a device comment with a part omitted, the device comment is taken into consideration as shown in Fig. 4 (c) in consideration of the case where the program creator cannot fully understand. It is also possible to display without omission.

As a specific operation method, it is conceivable to give an instruction to display the device comment without omitting from the operation menu of the program creation support device 1. As another method, if the line number for which the device comment is to be displayed is designated by clicking the line number with a mouse or the like, as described above, as shown in Fig. 4B, immediately after the line, the text is appended. Since the text attachment information display area 30 by the information display part 19 is provided, in this state, by clicking on the text attachment information display area again with a mouse, FIG. 4 (c) will not be omitted. As shown in Fig. 1, there is also a method for specifying all device comments to be displayed. By any method, when such an instruction is given, the text accompanying information display unit 19 repeatedly displays a device comment which is not omitted, over a plurality of lines as shown in Fig. 4C (Fig. In 4 (b), the device comment "Operation result storage" of "D124" is partially omitted and displayed as "Operation result". In FIG. 4 (c), the device comment "Operation result" of "D124" is stored. ”Is displayed).

The processing flow in this case is as shown in FIG. In FIG. 5, a difference from FIG. 3 is that in FIG. 5, the processing of steps S6 to S10 in FIG. 3 is omitted, and instead of steps S1, S2, S3, S4, S5, and S11 in FIG. 3, steps S1A and S2A. , S3A, S4A, S5A, and S11A are provided.

First, in step S1A, the text program editing unit 11 determines whether or not an instruction of device comment non-display is displayed for the entire text program. If the instruction has been received, the process proceeds to step S3A, and the processes of steps S3A to S5A and S11A are performed for every line included in the text program. On the other hand, when the said instruction is not received, it progresses to step S2A.

In step S2A, the text program editing unit 11 determines whether or not the device comment non-display indication for one line included in the text program has been received. If the instruction is not received, the flow returns to step S1A. On the other hand, if the said instruction | command is received, the process of step S3A-S5A and S11A is performed about the row.

In addition to the device, a variable is also used for the description of the text program, so that the used device extraction unit 13 refers to the text program display unit 18 or the text program storage file 8 to extract the variable with the device in step S3A. do.

Next, in step S4A, the used device accessory information extracting unit 14 is set for the device extracted in step S3A with reference to the device accessory information setting unit 12 or the device accessory information storing file 9. Extract the device comment. And the process of step 4A is the same as that of step 4 of FIG.

Next, in step S5A, the use device display position extraction unit 15 refers to the text program displayed by the text program display unit 18, and extracts the display positions of the device and the variable, respectively. Here, as shown in FIG.4 (c), the display position of "D124" counts from the head of a line by half angle, and the sixth character, the display position of "D123" counts from the head of a row, and it is 16 by half angle. In addition to the character, the display position of the variable "sArg" is counted from the beginning of the line and extracted at the 25th character in half angles. Here, it is not necessary to omit the device comment by the use device attachment information omission unit 16 (that is, there are no steps corresponding to steps S6 to S10 in FIG. 3).

Next, in step S11A, the text attachment information display unit 19 provides the text attachment information display area 30. In the text attachment information display area 30, the device "D124" is displayed from the beginning of the line. The device comment "storing of the calculation result" is displayed with the sixth character as the display position at half-width. However, at this time, in order to empty the display position and the interval of the next device "D123", it repeats at the front half of the display position of "D123" (that is, the 15th character half-width from the beginning of a line), Device comment "Store operation result" is displayed.

The processing flow of the program creation support device 1 according to the fourth embodiment is basically the same as the processing flow of the program creation support device 1 according to the first embodiment shown in FIG. 3, and the "device" of FIG. "Is replaced by" label. "

That is, first, in step S1C, the text program editing unit 11 determines whether or not an instruction for displaying the label attachment information for the entire text program is received. If the instruction is received, the process proceeds to step S3C, and the processes of steps S3C to S11C are performed for every line in every line included in the text program. On the other hand, when the said instruction is not received, it progresses to step S2C.

In step S2C, the text program editing unit 11 determines whether or not the display of the label attachment information for one line included in the text program has been instructed. If the instruction is not received, the flow returns to step S1C. On the other hand, if the said instruction | command is received, the process of step S3C-S11C is performed about the row.

In step S3C, the use device extraction unit 13 refers to the text program display unit 18 or the text program storage file 8 and performs a process of extracting a label described in the text program.

In step S4C, the use device accessory information extracting unit 14 is set for the label extracted in step S3C with reference to the label and accessory information setting unit 17 or the label and accessory information preservation file 10. Extract the label comment.

In step S5C, the use device display position extraction part 15 refers to the text program displayed by the text program display part 18, and displays where the label extracted in step S3C is displayed in the text program. Extract the location.

In step S6C, the use device attachment information omission unit 16 determines whether there is a next label displayed in the same row as the display position of the label extracted in step S5C. If there is a next label, the process proceeds to step S7C. If there is no next device, the process proceeds to step S9C.

In step S7C, the use device attachment information omitting unit 16 obtains the difference between the display position of the label extracted earlier and the display position of the label extracted next, and calculates the difference of the label comment of the previously extracted label. The number of characters that can be displayed.

Next, in step S8C, the use device attachment information omission unit 16 compares the number of displayable characters obtained in step S7C with the number of characters of the label comment of the label extracted previously. As a result of the comparison, if the number of characters in the label comment is less than or equal to the number of characters that can be displayed, the flow proceeds to step S9C. If the number of characters in the label comment exceeds the number of characters that can be displayed, the flow proceeds to step S10C.

In step S9C, since the number of characters in the label comment is less than or equal to the number of characters that can be displayed, it is not necessary to omit the label comment. Therefore, the use device attachment information omitting unit 16 does not perform the omission process and proceeds to step S11C. .

In step S10C, since the number of characters in the label comment exceeds the number of characters that can be displayed, the use device attachment information omitting unit 16 selects a part of the label comment so that the number of characters in the label comment is within the range of characters that can be displayed. Omitting processing to be omitted is performed, and the flow then proceeds to step S11C.

In step S11C, the text accessory information display unit 19 receives the label comment obtained in step S9C or step S10C and the display position information from the use device accessory information omit unit 16, and transmits the information to the text program display unit 18. A text appended information display area 30 is provided between the lines of the text program displayed by the text program, and the label comments obtained in step S9C or step S10C are displayed as shown in Fig. 13B.

As shown in Fig. 13C, two text attachment information display areas 30 may be provided, and both the label comment and the device to which the label is assigned may be displayed at the same time.

In addition, about the method of the omission process of the label comment of step S10C, it is basically the same as the method of the omission process of the device comment of step S10 of FIG. That is, the method of making the fixed length with respect to the number of characters which can be displayed, or the method of making the number of characters same as the number of characters of the said label into the number of characters which can be displayed in a label comment is considered, In this embodiment, it is the same from the said label display position. Since the number of characters up to the next label display position of the line can be displayed most of the number of characters in the label comment, an example using this method will be described.

In addition, the text accompanying information display unit 19 displays a label comment when receiving the operation of displaying the label comment from the program creator, and accepts an operation of making the label comment from the program creator non-display. At one time it shall be invisible. The default value is not displayed.

13 shows an example of a text program editing unit 11 of the program creation support device 1 according to the fourth embodiment of the present invention. Hereinafter, it demonstrates concretely accordingly. In the following, a description will be given of the third line of the text program for the purpose of displaying a label comment.

First, as shown in Fig. 13A, the text program display section 18 of the text program editing section 11 displays the text program and the program comment described by the program author.

(Step S1C)

In response to this, the program author performs an operation of displaying a label comment. As a specific operation method, it is conceivable to give an instruction to display a label comment from the operation menu of the program creation support device 1, in which case, the process of displaying the label comment for the entire text program, i.e., all lines of the program text. Will be done.

(Step S2C)

As another method, as shown in Fig. 13A, the line number is displayed at the head of each line of the text program displayed by the text program display unit 18, so that the program creator is responsible for the line number. The line number for which the label comment is to be displayed is designated by clicking with a mouse or the like. In this case, the process of displaying the label comment is performed for only one line of the specified text program. Hereinafter, a description will be given of a case in which the program author has an operation for displaying a label comment on the third line of the text program.

(Step S3C)

The use device extracting unit 13 refers to the label and the accessory information setting unit 17 or the label set in the label and the accessory information storage file 10, while the text program display unit 18 or the text program storage file is stored. Referring to (8), a process of extracting the label described in the third line of the text program is performed. Here, as shown to Fig.13 (a), "Ravel" and "Label" are extracted.

(Step S4C)

Next, the use device attachment information extraction unit 14 displays the label comments set for the labels extracted in step S1C, and the label and attachment information setting unit 17 or the label and attachment information storage file 10. Refer to and extract. Here, as shown to Fig.13 (d), label comment "voltage correction" is extracted with respect to label "Ravel", and label comment "voltage measurement" is extracted with respect to label "Label".

(Step S5C)

In addition, the use device display position extraction unit 15 extracts the display position where the label extracted in step S3C is displayed in the text program displayed by the text program display unit 18. Here, it is extracted that the display position of "Ravel" is the sixth character in half angle counting from the beginning of a line, and the display position of "Label" is the 16th character in half angle counting from the beginning of a line.

Here, since two labels are extracted in one line, regarding the label comment "voltage correction" set for the previously extracted label "Ravel", the limitation of the number of display characters is checked, and if necessary, the omission process is performed. .

(Step S7C)

The use device attachment information abbreviation part 16 first takes a label comment of "Ravel" from the display position of the label "Ravel" extracted in step S5C, and the display position of the next label "Label" in the same line. Calculate the number of characters that can be displayed. Since "Ravel" subtracts 6 from 16 because the next is "Label", and the difference is calculated to 10, since it is necessary to secure one half-width character to empty the space with the next label "Label", From 10, 1 is subtracted again and the number of characters that can be displayed is calculated to be 9 characters by half size. In addition, about "Label", since there is no next, there is no limit to the number of displayable characters.

(Step S9C, S10C)

If the number of characters in the label comment is larger, the process of omitting the label comment to the number of characters that can be displayed is performed. Because label comment "voltage correction" is four characters (eight characters at full size) about "Ravel" here, it is not necessary to omit this in nine characters (half point cut in four characters at full size), Just as good. In addition, about "Label", since there is no restriction | limiting in the number of characters which can be displayed, it becomes "voltage measurement" as it is.

(Step S11C)

Finally, the text program editing section 11 displays the text appendage information by the text appendage information display section 19 immediately after the third line displayed by the text program display section 18, as shown in Fig. 13B. The area 30 is provided, and for "Ravel", the sixth character is displayed at half-width by counting from the beginning of the line, and "voltage correction" which is a label comment is displayed, and for "Label", The device comment "voltage measurement" is displayed with the 16th character as the display position half-width from the head of the line.

In addition, the display of the abbreviated-labeled comment can be provided with a function of displaying the label comment without performing abbreviation processing in consideration of the case where the contents cannot be sufficiently understood, which is the same as that of the first embodiment. .

In the case of a program created using a label, in addition to the label comment display, the label assignment information is also provided for the device to which the label is assigned, so that a function for displaying this can be provided.

As a specific operation method, the method of instructing display of the attached information regarding a label assignment destination from the operation menu of the program creation support apparatus 1 is considered. Alternatively, when the line number for which the label comment is to be displayed is designated by clicking the line number with the mouse or the like, the text accessory information display area 30 is provided by the text accessory information display unit 19 immediately after the line. Therefore, there is also a method such as replacing the instruction to display the label assignment information by clicking the text appended information display area again with the mouse. When such an instruction is given, the text appended information display unit 19 displays a device and a device comment, which is information on a label assignment destination, as shown in Fig. 13C.

The processing flow in this case is the same flow as FIG. 12 described above. The difference from the foregoing description is that in step S4C, not only the label comment but also the address of the device to which the label is assigned is extracted, and in step S11C, not only the label comment but also the device to be assigned is displayed.

That is, the label is first extracted (step S3C, which is the same as step S3), and then the display position of the label is extracted with reference to the device and device comment to which the label is assigned (step S4C) (step S5C, which is Same as step S5). The number of characters that can be displayed is calculated (step S7C), and the omission process is performed as necessary for the device comment set in the device to which the label is assigned. Regarding "Ravel", since there is a label "Label" extracted next, it is omitted as the "calculation result" because the limit of the number of characters that can be displayed by nine characters at half-width is limited. On the other hand, since there is no limitation with respect to "Label", it is not necessary to omit it. Finally, the text attachment information display unit 19 provides the text attachment information display area 30. As for the label "Ravel," the assignment device "D124" and the omitted device comment "operation result" of the label are provided. ", And the label" Label "displays the device" D123 "to which the label is assigned and the device comment" Storage of the measurement result "which did not need to be omitted.

In addition, in order to clearly display whether the display content is a label comment or a device assignment destination device comment, for example, in the example of FIG. 13 (c), the display content is a label. In the case of a comment, "L" is displayed at the head of the line of the text sub information display area 30 (i.e., the portion where the line number is displayed in the text program display unit 18), and in the case of a device comment to which the label is assigned. "D" is shown and the example which distinguishes is shown.

In the fourth embodiment, in this way, even when a program of a controller having an input / output terminal is created in a text language format, the display position of the label used in the text program is set to explain the contents of the label in detail. The label comments, the device to which the label is assigned, and the device comments, such as the device comments, can be displayed, and the program author has made the effort of describing and inserting the supplementary description of the program as a comment by using the comment-out designation symbol. In addition, it is possible to ensure the readability of the program in the text language format.

In addition, also in the fourth embodiment, a case of separately generating and outputting a print output text program storage file 21 in which label attachment information is inserted between lines of a text program can be realized in the same manner as in the second embodiment. have.

14 shows an example of the printing output of the program creation support device 1 according to the fourth embodiment. The configuration of the program creation support device 1 is a configuration in which the text appended information insertion unit 20 and the text output file 21 for print output are provided in the configuration of FIG. 11 described above. The operations of the text appending information inserting unit 20 and the printout text program storage file 21 are the same as those described in the second embodiment, and thus description thereof is omitted here.

In addition, in the example of FIG. 14 (b), the label attachment information (label comment) and the device attachment information (the device to which the label is assigned and the device attachment information) are used for the printout text program storage file 21 by using the comment out designation symbol //. The example in which both device comments) are inserted and output is shown.

According to the fourth embodiment, the contents of the label immediately after (or immediately before) the display position of the label used in the text program, even when the program of the controller having the input / output terminals is produced in the text language format in this way. It becomes possible to generate the printout text program storage file 21 into which the label comment set and the label assignment device accessory information set to explain in detail as a program comment can be printed out or displayed by other means. By doing so, the program author can save the effort of describing and inserting supplementary description of the program as a program comment by using the comment-out designation symbol by himself / herself, and also ensures the readability of the program in the text language format.

In addition, in the fourth embodiment, the case where the present value of the label is displayed can be realized in the same manner as in the case of the device of the third embodiment.

In the case of a text program in which a label and a device are used in combination, (1) a method of extracting only a device to display device accessory information, and (2) only a label is extracted to provide label accessory information (label comment or label assignment destination). Device accessory information), and (3) a method of extracting both the label and the device to display the label accessory information and the device accessory information. The method of (1) is as described in the first embodiment, and the method of (2) is as described in the fourth embodiment. When combined, the method of (3) is realized.
