  The present invention relates to a program creation support apparatus and a program creation support method, and more particularly to a program creation support apparatus and program creation for creating an operation program executed by a controller having an input / output terminal in a text language format using devices and labels. It relates to support methods.

  Conventionally, PLCs (Programmable Logic Controllers), CNCs (Computerized Numerical Controls) controllers, motion controllers, robot controllers, data collection controllers, and the like are known as controllers having input / output terminals.

  These controllers have a static memory area and a dynamic memory area. The static memory area holds input / output terminal values and global values controlled by a plurality of programs. A dynamic memory area holds local values that are controlled only by one program. Hereinafter, these memory areas are referred to as devices.

  In the PLC described in Non-Patent Document 1 below, device characters (X, Y, M, D, etc.) are predetermined according to the data type. For example, an input device is an X device, an output device is a Y device, internally used bit data (internal relay) is an M device, and internally used word data (register) is D. As a device.

  The program is described using the device address. The program creation support device is provided with an editor that supports the creation of this program, and at the same time, has a function of communicating with the controller to transfer a completed program or to monitor a running program. Yes.

  For example, the following program creation support apparatus of Non-Patent Document 1 includes a program creation editor based on a ladder diagram. In addition to a function that inserts a program's supplementary description as a program comment (called a statement in the example of Non-Patent Document 1 below) and a device comment that explains the device in detail so that the program can be created more easily The function to do is provided.

  In addition, a device comment display function is provided for the devices described in the ladder diagram. This makes it possible to improve the readability of the ladder diagram without requiring the program creator to insert a program comment. In particular, since many static devices are used in the measurement control program of the controller, it is useful to set a device comment for such a static device and display it on a ladder diagram.

  In recent years, in order to improve the reusability of programs, there is also a function to define a label that is an alias for a device, create a program using the label, and separately set the label to be assigned to the device. ing. This label also has a function of setting a label comment that explains the contents of the label in detail.

  And the function which displays a label comment with respect to the label described in the ladder diagram is provided. This makes it possible to improve the readability of the ladder diagram without requiring the program creator to insert a program comment. In particular, in a measurement control program with high reusability, labels are often used. Therefore, it is useful to set a label comment for such a label and display it on a ladder diagram.

Embodiment 1 FIG.
The present invention is a program creation support apparatus for creating a program executed by a controller having input / output terminals in a text language format using a device and a label. FIG. 1 shows a hardware configuration of a program creation support apparatus 1 according to the present invention. The program creation support apparatus 1 is composed of, for example, a personal computer, and includes a microprocessor 2, a display unit 3, an input unit 4, a storage unit 5, and a communication unit 6, as shown in FIG. Further, a controller 7 is connected to the program creation support apparatus 1 as shown in FIG. The program creation support device 1 communicates with the controller 7 to transfer the completed program to the controller 7 and monitor the program being executed by the controller 7. A program for operating the controller 7 is stored in the storage unit 5 as a file. The display unit 3 is a monitor that displays various information of the program creation support apparatus 1. The input unit 4 is a mouse or a keyboard. That is, the program creator inputs a program using the input unit 4 and the contents are displayed on the display unit 3. The created program is transferred to the controller 7 via the communication unit 6 and executed by the controller 7.

  FIG. 2 shows a configuration (software configuration) of the program creation support apparatus 1 according to Embodiment 1 of the present invention. As shown in FIG. 2, the program creation support apparatus 1 is provided with a device ancillary information setting unit 12 for setting a device comment describing the contents of a device. The device accessory information setting unit 12 stores the set device comment as the device accessory information storage file 9 and reads the stored device comment from the device accessory information storage file 9.

  The program creation support apparatus 1 is provided with a text program editing unit 11 that creates a program to be executed by the controller 7 in a text language format using a device.

  The text program editing unit 11 is provided with a text program display unit 18. The text program editing unit 11 displays the text program being created on the text program display unit 18 and edits it based on input from the program creator. The text program editing unit 11 stores the edited text program as the text program storage file 8 and reads the stored text program from the text program storage file 8.

  Further, as shown in FIG. 2, the text program editing unit 11 further includes a used device extracting unit 13, a used device attached information extracting unit 14, a used device display position extracting unit 15, and a used device attached information omitting unit. 16 and a text attached information display unit 19 are provided.

  The used device extraction unit 13 refers to the text program display unit 18 or the text program storage file 8 and extracts a device described in the text program. The extracted device is input to the used device attached information extracting unit 14 and the used device display position extracting unit 15.

  The used device attached information extracting unit 14 refers to the device attached information setting unit 12 or the device attached information storage file 9 and extracts a device comment set for the device extracted by the used device extracting unit 13.

  The used 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 used device extraction unit 13.

  The used device ancillary information omitting unit 16 calculates the number of characters that can be displayed as a device comment based on the device display position extracted by the used device display position extracting unit 15 and the next device display position on the same line. The used device attached information omitting unit 16 compares the calculated number of displayable characters with the number of characters of the device comment extracted by the used device attached information extracting unit 14. If the number of characters of the extracted device comment is larger than the number of displayable characters as a result of comparison, the used device attached information omitting unit 16 sets the device comment so that the number of characters of the device comment falls within the range of displayable characters. A process of omitting a part of the comment (hereinafter referred to as an abbreviated process) is performed. On the other hand, if the number of characters of the extracted device comment is equal to or less than the number of characters that can be displayed, the omission process is not performed and the device comment is left as it is.

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

  The text attached information display unit 19 will be specifically described. Assume that the text program is displayed on the display unit 3 by the text program display unit 18 as shown in FIG. In the text program, for example, “D124” and “D123” on the third line are devices. At this time, as shown in FIG. 4B, the text ancillary information display unit 19 displays the line (that is, the third line) of the text program in which these devices are displayed and the line immediately after that (that is, the four lines). A text ancillary information display area 30 is provided between the lines between the first and second eyes, and device comments such as “calculation result” and “storage of measurement result” are displayed there. In addition, the text attached information display unit 19 has a head of the display position of each device and a head of the display position of the device comment corresponding to the device based on the information of the display position from the used device attached information omitting unit 16. Set the display position of device comments so that they are arranged vertically. In the example of FIG. 4B, the display position of the first character “D” of the device “D124” and the display position of the first character “act” of the corresponding device comment “calculation result” are in the vertical direction. Are lined up. Similarly, the display position of the first character “D” of the device “D123” and the display position of the first character “total” of the corresponding device comment “measurement result storage” are arranged in the vertical direction.

  FIG. 4B shows an example in which the device comment is displayed on the line immediately after the line on which the device is displayed. However, the present invention is not limited to this, and the device comment is displayed on the line on which the device is displayed. You may make it display on the line immediately before.

  FIG. 3 shows a processing flow of the program creation support apparatus 1 according to Embodiment 1 of the present invention. First, in step S1, the text program editing unit 11 determines whether or not an instruction to display a device comment for the entire text program has been input by the program creator. When the instruction is input, the process proceeds to step S3, and the processes of steps S3 to S11 are performed for each line for all lines included in the text program. On the other hand, if the instruction has not been received, the process proceeds to step S2.

  In step S2, the text program editing unit 11 determines whether an instruction to display a device comment for one line included in the text program has been input by the program creator. If the instruction has not been received, the process returns to step S1. On the other hand, if the instruction is received, the processes of steps S3 to S11 are performed on the line.

  In step S <b> 3, the used device extraction unit 13 refers to the text program display unit 18 or the text program storage file 8 and extracts a device described in the text program.

  Next, in step S4, the used device attached information extracting unit 14 refers to the device attached information setting unit 12 or the device attached information storage file 9, and the device comment set for the device extracted in step S3. To extract.

  Next, in step S5, the used device display position extraction unit 15 refers to the text program display unit 18, and the device extracted in step S3 is displayed in the text program displayed by the text program display unit 18. And the display position is extracted.

  Next, in step S6, the used device attached information omitting unit 16 determines whether or not there is a next device displayed on the same line as the line on which the device extracted in step S3 is displayed. That is, it is determined whether or not there are a plurality of devices in one row where the devices are extracted in step S3. As a result of the determination, if there is a next device, the process proceeds to step S7, and if there is no next device, the process proceeds to step S9.

  In step S7, the used device ancillary information omitting unit 16 obtains a difference between the display position of the previously extracted device and the display position of the next extracted device, and calculates the difference with respect to the previously extracted device. Set as the number of displayable characters for device comments.

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

  In step S9, since the number of characters in the device comment is equal to or less than the number of characters that can be displayed, it is not necessary to omit the device comment. Therefore, the used device attached information omitting unit 16 proceeds to step S11 without performing the omitting process.

  In step S10, since the number of characters in the device comment exceeds the number of characters that can be displayed, the device-attached information omitting unit 16 uses the device comment so that the number of characters in the device comment falls within the range of displayable characters. Omission processing is omitted, and the process proceeds to step S11.

  In addition to the above method, various methods are conceivable as a method for setting the number of displayable characters. For example, since the number of characters of the device is about 4 single-byte characters, there is a method of setting the number of displayable characters to a fixed length, such as 4 single-byte characters. Alternatively, there is a method in which the number of characters of the device is the number of characters that can be displayed in the device comment and the device comment is displayed within the range of the number of characters of the device. However, as described above, the number of characters that can be displayed is the number of characters between the display position of the previous device and the display position of the next device on the same line. In this embodiment, this method is used because the method can be performed.

  In addition, with respect to the device comment omission processing for the number of displayable characters performed in step S10, only the number of characters that can be displayed from the beginning of the device comment characters are deleted, and the subsequent characters are deleted. If is set with kanji and hiragana, there is a method of deleting hiragana while leaving only kanji. In this embodiment, any of the methods may be used. However, in order to simplify the explanation, in the following explanation, only the number of characters that can be displayed from the beginning is left and the subsequent characters are deleted. This method will be described as an example.

  In step S11, the text ancillary information display unit 19 receives the device comment obtained in step S9 or step S10 and the information on the display position from the used device ancillary information omitting unit 16, and displays it on the text program display unit 18. The device comment obtained in step S9 or step S10 is displayed between the lines of the text program to be executed.

  The text ancillary information display unit 19 displays a device comment when receiving an instruction to display a device comment from the program creator, and receives an instruction to hide the device comment from the program creator. In case, switch to hide. The default value is not displayed.

  FIG. 4 shows an example of the operation of the text program editing unit 11 of the program creation support apparatus 1 according to Embodiment 1 of the present invention. Hereinafter, it demonstrates concretely along with this.

  First, as usual, as shown in FIG. 4A, the text program display unit 18 of the text program editing unit 11 displays the text program and the program comment written by the program creator.

(Step S1 in FIG. 3)
On the other hand, the program creator performs an operation to display a device comment. As a specific operation method, an instruction to display a device comment from the operation menu of the program creation support apparatus 1 can be considered. In this case, the device is applied to the entire text program, that is, all lines of the program text. Processing to display comments will be performed.

(Step S2 in FIG. 3)
As another method, as shown in FIG. 4A, 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 Designate the line number to display the device comment by clicking the line number with the mouse. In this case, the device comment is displayed only for one line of the designated text program. In the following, a case will be described in which the program creator has performed an operation to display a device comment for the third line of the text program.

(Step S3 in FIG. 3)
The used device extraction unit 13 refers to the text program display unit 18 or the text program storage file 8 and extracts the device described in the third line of the text program. Here, “D124” and “D123” are extracted as devices.

(Step S4 in FIG. 3)
Next, the used device attached information extracting unit 14 refers to the device attached information setting unit 12 or the device attached information storage file 9 and refers to the two devices “D124” and “D123” extracted by the used device extracting unit 13. Extract device comments set for each. Here, as shown in FIG. 4D, the device comment “storage of calculation results” is extracted for the device “D124”, and the device comment “storage of measurement results” is extracted for the device “D123”. Is done.

(Step S5 in FIG. 3)
In addition, the used device display position extracting unit 15 refers to the text program display unit 18 and displays the two devices “D124” and “D123” extracted by the used device extraction unit 13 on the text program display unit 18. Detects where the text program is displayed and extracts the display position. Here, the display position of “D124” is the sixth character in half-width from the beginning of the line, and the display position of “D123” is the sixteenth character in the half-width from the beginning of the line. Extracted.

(Step S6 in FIG. 3)
Here, since two devices are extracted in one line, the device comment “store calculation result” set for the previously extracted device “D124” is about the limitation on the number of display characters. It is necessary to perform the determination in step S8, and if the number of characters that can be displayed is exceeded, the process of omitting step S10 is performed.

(Step S7 in FIG. 3)
First, the used device ancillary information omitting unit 16 can display the device comments “D124” and “D123” from the display position of the device “D124” and the display position of the next device “D123” on the same line. Calculate the number of characters. For the device “D124”, since there is the next device “D123”, 6 is subtracted from 16 which is the respective display position, and the difference is calculated to be 10. This 10 may be the number of characters that can be displayed, but preferably one half-width character must be 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. Therefore, 1 is further subtracted from 10 to calculate the number of displayable characters as 9 half-width characters. For “D123”, since there is no next device, the number of characters that can be displayed is not limited.

(Steps S8 to S10 in FIG. 3)
Next, compare the number of characters in the device comment with the number of characters that can be displayed, and if the number of characters in the device comment is larger, omit part of the device comment so that it falls within the range of characters that can be displayed I do. Here, for the device “D124”, since the device comment “Store calculation result” is 7 full-width characters (14 characters in half-width conversion), it is 9 characters in half-width conversion (rounded down to 4). Character). The simplest method is to leave only 4 full-width characters from the beginning, delete the rest, and use it as the “calculation result”. For “D123”, there is no limit to the number of characters that can be displayed, so “measurement result storage” is used as it is.

(Step S11 in FIG. 3)
Finally, the text program editing unit 11 causes the text ancillary information display unit 19 to immediately follow the third line of the text program displayed on the text program display unit 18 as shown in FIG. A display area 30 is provided, and for the device “D124”, the device comment “calculation result” is displayed with the sixth character as the display position from the top of the line. This is obtained by omitting the original device comment “storage of calculation results”. For the device “D123”, the 16th character from the beginning of the line is the display position, and the device comment “Storing measurement results” is displayed. The device comment “store measurement result” is displayed as the original device comment because no omission processing is required. In addition, although the example in which the text ancillary information display area 30 by the text ancillary information display unit 19 is provided immediately after the corresponding line has been described, the present invention is not limited thereto, and the text ancillary information display area 30 may be provided immediately before the corresponding line.

  In order to clearly distinguish whether the display is by the text program display unit 18 or the display by the text ancillary information display unit 19, for example, in FIG. 4B, the display by the text program display unit 18 is performed. , The line number (1, 2, 3,...) Is displayed at the beginning of each line, and “D” is displayed at the beginning of the line for the display by the text ancillary information display unit 19. To distinguish them.

  In the present embodiment, as shown in FIG. 4C, in consideration of the case where the program creator cannot fully understand the display of a device comment with a part omitted, as shown in FIG. 4B. It is also possible to display without omitting the device comment.

  As a specific operation method, an instruction to display without omitting a device comment from the operation menu of the program creation support apparatus 1 can be considered. As another method, when a line number for which a device comment is to be displayed is designated by clicking the line number with a mouse or the like, as described above, text is attached immediately after that line as shown in FIG. Since the text ancillary information display area 30 is provided by the information display unit 19, in that state, by clicking the text ancillary information display area with a mouse, a device comment is not omitted, as shown in FIG. There is also a method to specify that all device comments are displayed. When such an instruction is given by any method, the text ancillary information display unit 19 wraps and displays a device comment that is not omitted over a plurality of lines as shown in FIG. 4C (FIG. 4). In (b), the device comment “storage of calculation result” of “D124” is partially omitted and displayed as “calculation result”. However, in FIG. 4C, the device comment “calculation of“ D124 ”is displayed. All stored results are displayed).

  The processing flow in this case is as shown in FIG. 5 differs from FIG. 3 in that the processing in steps S6 to S10 in FIG. 3 is omitted in FIG. 5, and steps S1A, S1, S5, S11 in FIG. S2A, S3A, S4A, S5A, and S11A are provided.

  First, in step S1A, the text program editing unit 11 determines whether or not an instruction for device comment non-omission display for the entire text program has been received. If the said instruction | indication is received, it will progress to step S3A and will process step S3A-S5A and S11A for every line with respect to all the lines contained in a text program. On the other hand, if the instruction has not been received, the process proceeds to step S2A.

  In step S <b> 2 </ b> A, the text program editing unit 11 determines whether or not a device comment non-omission display instruction has been received for one line included in the text program. If the instruction has not been received, the process returns to step S1A. On the other hand, if the instruction is received, the processes of steps S3A to S5A and S11A are performed on the line.

  Since the variable is used in addition to the device for the description of the text program, the used device extraction unit 13 refers to the text program display unit 18 or the text program storage file 8 and extracts the variable together with the device in step S3A. .

  Next, in step S4A, the device attached information extracting unit 14 refers to the device attached information setting unit 12 or the device attached information storage file 9 and sets the device comment set for the device extracted in step S3A. To extract. The process in step 4A is the same as step 4 in FIG.

  Next, in step S5A, the used 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 devices and variables. Here, as shown in FIG. 4C, the display position of “D124” is the sixth character in half-width from the beginning of the line, and the display position of “D123” is 16 half-width from the beginning of the line. In addition to the character, it is extracted that the display position of the variable “sArg” is the 25th character from the beginning of the line. Here, it is not necessary to omit the device comment by the used device attached information omitting unit 16 (that is, there are no steps corresponding to steps S6 to S10 in FIG. 3).

  Next, in step S11A, the text ancillary information display unit 19 provides a text ancillary information display area 30. In the text ancillary information display area 30, the device "D124" displays the sixth character in the first half of the line. As a position, the device comment “Store calculation result” is displayed. However, at this time, in order to leave a gap from the display position of the next device “D123”, it is one character before the display position of “D123” (that is, the 15th character from the beginning of the line). To display the device comment “Store calculation result”. Specifically, as shown in FIG. 4C, only the “calculation result” is displayed in the upper line, the “storage” portion is folded and displayed just below the display position of the “calculation result”. . For the device “D123”, the device comment “stores the measurement result” is displayed with the 16th character from the top of the line as the display position. At this time, similarly, in order to leave a space from the display position of the next variable “sArg”, it is one character before the display position of “sArg” (that is, the 24th character from the beginning of the line). Wrap it back and display the device comment “Store measurement result”. Specifically, as shown in FIG. 4C, only the “measurement result” is displayed in the upper line, the “stored” portion is folded and displayed immediately below the display position of the “measurement result”. . Since there is no device comment for the variable “sArg”, nothing is displayed.

  In the first embodiment, even when the program of the controller 7 having input / output terminals is created in the text language format in this way, immediately after (or immediately before) the display position of the device used in the text program. ), Device comments set to explain the contents of the device in detail can be displayed, eliminating the need for the program creator to manually insert a supplementary description of the program as a comment using the comment-out designation symbol. In addition, it is possible to ensure the readability of the text language format program.

Embodiment 2. FIG.

  In the third embodiment, even when the program of the controller 7 having input / output terminals is created in the text language format in this way, the current value of the device is used as the display position of the device used in the text program. It is possible to display immediately after (or immediately before), and it is possible to ensure readability when monitoring a text language program.

Embodiment 4 FIG.
In the fourth embodiment, a method for displaying label attached information in text programming using labels will be described. The hardware configuration of the program creation support apparatus 1 in the present embodiment is the same as the configuration shown in FIG.

  FIG. 11 shows the configuration (software configuration) of the program creation support apparatus 1 according to Embodiment 4 of the present invention. The difference between the configuration of FIG. 11 and the configuration of the first embodiment shown in FIG. 2 is that in FIG. 11, a label and attached information setting unit 17 and a label and attached information storage file 10 are added. It is. The other configuration is basically the same as the configuration of FIG.

  As shown in FIG. 11, the program creation support apparatus 1 is provided with a device attached information setting unit 12 for setting a device comment for a device. The device comment is stored in the device attached information storage file 9 and can be read out therefrom.

  Further, the program creation support apparatus 1 is provided with a label and attached information setting unit 17 for setting a label comment and an allocation destination device for the label. The set label and allocation destination device are stored in the label and attached information storage file 10 and can be read out therefrom.

  Further, the program creation support apparatus 1 is provided with a text program editing unit 11 so that the text program display unit 18 can display and edit the text program. The program is stored and read out as a text program storage file 8.

  In addition to these configurations, the present embodiment further includes a used device extraction unit 13, a used device attached information extracting unit 14, a used device display position extracting unit 15, a used device attached information omitting unit 16, and a text attached information display. A part 19 is provided. These configurations are basically the same as those provided in the first embodiment, except that each corresponds to not only a device but also a label.

  FIG. 12 shows a processing flow of the program creation support apparatus 1 according to Embodiment 4 of the present invention. The process flow of the program creation support apparatus 1 according to the fourth embodiment is basically the same as the process flow of the program creation support apparatus 1 according to the first embodiment shown in FIG. "Is replaced with" label ".

  That is, first, in step S1C, the text program editing unit 11 determines whether an instruction to display label attached information for the entire text program has been received. If the instruction has been received, the process proceeds to step S3C, and the processes of steps S3C to S11C are performed for each line for all lines included in the text program. On the other hand, if the instruction has not been received, the process proceeds to step S2C.

  In step S2C, the text program editing unit 11 determines whether or not an instruction to display label attached information for one line included in the text program has been received. If the instruction has not been received, the process returns to step S1C. On the other hand, if the instruction is received, the processes of steps S3C to S11C are performed on the line.

  In step S <b> 3 </ b> C, the used 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 used device attached information extracting unit 14 refers to the label and attached information setting unit 17 or the label and attached information storage file 10, and is set for the label extracted in step S3C. Extract comments.

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

  In step S6C, the used device ancillary information omitting unit 16 determines whether or not there is a next label displayed on the same line as the display position of the label extracted in step S5C. If there is a next label, the process proceeds to step S7C, and if there is no next device, the process proceeds to step S9C.

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

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

  In step S9C, since the number of characters in the label comment is equal to or less than the number of characters that can be displayed, it is not necessary to omit the label comment. Therefore, the used device attached information omitting unit 16 proceeds to step S11C without performing the omission processing.

  In step S10C, since the number of characters in the label comment exceeds the number of characters that can be displayed, the device-attached information omitting unit 16 uses the label comment so that the number of characters in the label comment falls within the range of characters that can be displayed. Omission processing is omitted, and the process proceeds to step S11C.

  In step S11C, the text ancillary information display unit 19 receives the label comment obtained in step S9C or step S10C and the information on the display position from the used device ancillary information omitting unit 16, and displays it on the text program display unit 18. A text ancillary information display area 30 is provided between the lines of the text program to be displayed, and the label comment obtained in step S9C or step S10C is displayed as shown in FIG.

  As shown in FIG. 13C, two text ancillary information display areas 30 may be provided to display both the label comment and the label assignment destination device at the same time.

  Further, the label comment omission processing method in step S10C is basically the same as the device comment omission processing method in step S10 of FIG. In other words, there are a method of setting the number of displayable characters to a fixed length and a method of setting the same number of characters as the number of characters of the label to the number of characters that can be displayed in the label comment. Since the number of characters up to the next label display position is the most displayable number of characters in the label comment, an example using this method will be described.

  The text ancillary information display unit 19 displays a label comment when an operation for displaying a label comment from the program creator is received, and performs an operation for hiding the label comment from the program creator. It will be hidden when it is accepted. The default value is hidden.

  FIG. 13 shows an example of the text program editing unit 11 of the program creation support apparatus 1 according to Embodiment 4 of the present invention. Hereinafter, it demonstrates concretely along with this. Hereinafter, a case where an operation for displaying a label comment is performed on the third line of the text program will be described.

  First, as usual, as shown in FIG. 13A, the text program display unit 18 of the text program editing unit 11 displays a text program and a program comment written by the program creator.

(Step S1C)
On the other hand, the program creator performs an operation to display a label comment. As a specific operation method, an instruction to display a label comment from the operation menu of the program creation support apparatus 1 can be considered. In this case, the label is applied to the entire text program, that is, all lines of the program text. Processing to display comments will be performed.

(Step S2C)
As another method, as shown in FIG. 13A, 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 Specify the line number to display the label comment by clicking the line number with the mouse. In this case, the label comment is displayed only for one line of the designated text program. In the following, a case will be described in which the program creator performs an operation for displaying a label comment for the third line of the text program.

(Step S3C)
The used device extracting unit 13 refers to the text program display unit 18 or the text program storage file 8 while referring to the label set in the label and attached information setting unit 17 or the label and attached information storage file 10. Then, a process of extracting the label described in the third line of the text program is performed. Here, as shown in FIG. 13A, “Label” and “Label” are extracted.

(Step S4C)
Next, the used device attached information extracting unit 14 refers to the label and attached information setting unit 17 or the label and attached information storage file 10 for the label comment set for the label extracted in step S1C. To extract. Here, as shown in FIG. 13D, the label comment “voltage correction” is extracted for the label “Label”, and the label comment “voltage measurement” is extracted for the label “Label”.

(Step S5C)
Further, the used 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 “Ravel” display position is the sixth character in half-width from the beginning of the line, and the “Label” display position is the sixteenth character in half-width from the beginning of the line.

  Here, since two labels are extracted in one line, the label comment “voltage correction” set for the previously extracted label “Ravel” is checked for the limitation on the number of display characters and necessary. If there is, omit the process.

(Step S7C)
The used device attached information omitting unit 16 first displays the label comment of “Label” from the display position of the label “Label” extracted in step S5C and the display position of the next label “Label” in the same line. Calculate the number of possible characters. “Ravel” is calculated to be 10 by subtracting 6 from 16 since the next is “Label”, and the difference is calculated as 10 one-byte half-width characters for the next label “Label”. Since it is necessary to secure the minutes, 1 is further subtracted from 10 to determine that the number of displayable characters is 9 single-byte characters. Since “Label” is not next, there is no limit to the number of characters that can be displayed.

(Steps S9C, S10C)
If the number of characters in the label comment is larger, processing for omitting the label comment to the number of characters that can be displayed is performed. Here, since the label comment “voltage correction” for “Ravel” is 4 characters in half-width (8 characters in half-width), it is omitted to 9 characters in half-width (rounded down to 4 characters). It is not necessary and can be left as it is. For “Label”, there is no limit to the number of characters that can be displayed, so “voltage measurement” is used as it is.

(Step S11C)
Finally, as shown in FIG. 13 (b), the text program editing unit 11 opens a text attached information display area 30 by the text attached information display unit 19 immediately after the third line displayed on the text program display unit 18. For “Label”, the sixth character is displayed in half-width from the beginning of the line, and the label comment “Voltage correction” is displayed. For “Label”, the sixteenth character is displayed in half-width from the head of the line. Is displayed, and the device comment “Voltage measurement” is displayed.

  In addition, in consideration of the case where the contents of the abbreviated label comment cannot be fully understood, it is possible to provide a function of displaying the abbreviated label comment without performing the abbreviated process, as in the first embodiment. It is.

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

  As a specific operation method, a method of instructing display of attached information related to the label assignment destination from the operation menu of the program creation support apparatus 1 can be considered. Alternatively, when a line number for which a label comment is to be displayed is specified by clicking the line number with a mouse or the like, a text ancillary information display area 30 by the text ancillary information display unit 19 is provided immediately after the line, and further, text There is also a method in which the attached information display area is clicked with a mouse to replace the instruction for displaying the label assignment destination information. When such an instruction is given, the text attached information display unit 19 displays a device and a device comment, which are information related to the label assignment destination, as shown in FIG.

  The processing flow in this case is the same as that shown in FIG. The difference from the above description is that in step S4C, not only the label comment but also the address of the label assignment destination device is extracted, and in step S11C, not only the label comment but also the assignment destination device is displayed. .

  That is, first, a label is extracted (step S3C, which is the same as step S3), then a label assignment device and a device comment are referenced (step S4C), and a label display position is extracted (step S5C, This is the same as step S5). Then, the number of characters that can be displayed is calculated (step S7C), and omission processing is performed as necessary on the device comment set in the device to which the label is assigned. Since “Label” has a label “Label” extracted next, it is a limitation on the number of characters that can be displayed in 9 half-width characters, and is therefore omitted from “calculation result”. On the other hand, “Label” is not limited and need not be omitted. Finally, the text ancillary information display unit 19 provides a text ancillary information display area 30, and for the label “Ravel”, displays the assigned device “D124” of the label and the omitted device comment “calculation result”. For the label “Label”, the device “D123” to which the label is assigned and the device comment “storage of measurement result” that does not need to be omitted are displayed.

  For example, in the example of FIG. 13C, the text attached information display unit 19 clearly displays whether the display content is a label comment or a label assignment destination device comment. In this case, “L” is displayed at the beginning of the line of the text ancillary information display area 30 (that is, the part where the line number is displayed in the text program display unit 18). An example in which “D” is displayed and distinguished is shown.

  In the fourth embodiment, in this way, even when a controller program having input / output terminals is created in a text language format, the contents of the label are detailed in the display position of the label used in the text program. It is possible to display attached information related to the label, such as the label comment set for explanation, the device to which the label is assigned, and the device comment, and the program creator can supplement the program using the comment-out designation symbol. It is possible to save the trouble of describing and inserting the description as a comment and to ensure the readability of the text language program.

  In the fourth embodiment as well, the case where the print output text program storage file 21 in which the label attached information is inserted between the lines of the text program is separately generated and output is the same as in the second embodiment. realizable.

  FIG. 14 shows an example of the print output of the program creation support apparatus 1 according to the fourth embodiment. The configuration of the program creation support apparatus 1 here is a configuration in which the text ancillary information insertion unit 20 and the print output text program storage file 21 of FIG. 6 are further provided in the configuration of FIG. Since the operations of the text ancillary information insertion unit 20 and the print output text program storage file 21 are the same as those described in the second embodiment, description thereof is omitted here.

  In the example of FIG. 14B, the label output information (label comment) and the device attachment information (the device to which the label is allocated and the device to which the label is assigned) are used in the print output text program storage file 21 using the comment out designation symbol //. An example is shown in which both device comments are inserted and output.

  According to the fourth embodiment, even when the controller program having the input / output terminals is created in the text language format in this way, immediately after (or immediately before) the display position of the label used in the text program. It is possible to generate the print output text program storage file 21 in which the label comment set to explain the contents of the label and the information attached to the device to which the label is assigned are inserted as a program comment. Or by displaying it by other means, the program writer can save the time and effort to insert the program's supplementary description as a program comment using the comment-out designation symbol. Can be secured.

  In the fourth embodiment, the current label value can be displayed in the same manner as the device of the third embodiment.

  In the case of a text program that uses a mixture of labels and devices, (1) a method of extracting only the device and displaying the device attached information, and (2) an information of attaching the label by extracting only the label. There are a method of displaying (label comment and label assignment destination device attached information) and (3) a method of extracting both the label and the device and displaying the label attached information and the device attached information. The method of (1) is as described in the first embodiment, and the method of (2) is as described in the fourth embodiment. Realized.

  Thus, although said Embodiment 1-4 is good also as each separate embodiment, it is good also as a structure which combined each arbitrarily, and also in that case, each each shown in Embodiment 1-4 It goes without saying that the same effects as the effects can be obtained by the number of combined embodiments.
