In addition, comments are also reflected in the relay diagram in which the PC address does not appear directly in the drawing. In a control system cad device having a comment transcription means for obtaining comment information associated with a PC address and transcribing a comment in a cad drawing, a coil corresponding to a pc address in the drawing data is converted into XY coordinates. It has comment search means for searching for a clue, and the comment transfer means transfers a comment to the searched coil. This transfer process is a process of associating a coil with a comment by generating a character database for displaying or printing a comment and providing a pointer to the character database from the coil database side in the coil database. .

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a control system cad device having comment transcribing means, particularly comment transcribing means for I / O diagrams.

[0002]

[Prior art]

 In a control system CAD (Computer Aided Design or Computer Aided Draft), an input diagram (I diagram) and output diagram (O diagram) in one drawing (drawing of one file) of the relay diagram (relay diagram in a broad sense) It is common to handle both drawings. In the input diagram or output diagram (I / O diagram), when the comment was transcribed for the PC address, the comment was transcribed for the PC address (for example, “Y000”). Here, "PC" is a programmable controller, and "comment" is an annotation such as abnormal reset, automatic operation, or cycle stop. In addition, "input / output" when referring to input diagrams or output diagrams (I / O diagrams) refers to input / output to the programmable controller.

On the other hand, in a relay diagram (a relay diagram in a narrow sense) other than the input / output diagram, since the PC address is not handled, the comment is not transcribed.

This situation will be described with reference to FIG. FIG. 4 is a diagram showing a conventional comment transcription process. FIG. 4A is a part of the output diagram, and FIG. 4B shows a part of the PC address comment information. In the conventional comment transcription, the comment information corresponding to the PC address is acquired (see FIG. 4 (A)), and the comment is placed at the position corresponding to the PC address in the input diagram (FIG. 4 (A)). See). Therefore, the comment "Comment 1" corresponding to the PC address "Y0000" is transcribed to the right of the place where "Y0000" is drawn. Similarly, "comment 2" is arranged to the right of "Y0001" and "comment 3" is arranged to the right of "Y0002". The expression “comment 1” or the like specifically refers to an annotation such as automatic operation, cycle stop, start of start, or the like. Here, the PC address and the comment are handled as graphic elements of the input drawing, respectively, and are handled as information having XY coordinates on the drawing data (key database (DB)), so the XY coordinates are used as a clue. It is related.

However, in the (narrowly defined) relay diagram shown in FIG. 4C, since the PC address does not appear in the figure, a comment corresponding to the PC address should be placed in the output diagram. I couldn't.

[0006]

[Problems to be solved by the device]

 However, even in the narrowly defined relay diagram, it is desired to reflect the comment on the coil contact side. Therefore, the operator manually generates a new graphic element (graphic DB) to comment on the relay diagram. There was a problem of having to input.

The object of the present invention is to manage the comment as not corresponding to the PC address but to correspond to the coil, and to reflect the comment also in the relay diagram in which the PC address does not appear directly in the drawing. It is an object of the present invention to provide a control system cad device having a comment transcribing means that can be performed.

[0008]

[Means for Solving the Problems]

 The present invention that achieves the above-mentioned object obtains comment information associated with a PC address, and in a control system cad device equipped with a comment transcribing device for transcribing a comment in a cad drawing, it is added to a pc address in drawing data. It has a coil search means for searching for a corresponding coil by using the XY coordinates as a clue, and the comment transfer means executes a process of transferring a comment to the coil searched by the comment search means. It is a characteristic control system cad device.

[0009] Preferably, in the processing for posting the comment to the coil by the comment posting unit, a character database for displaying or printing the comment is generated, and the character database is pointed to from the database side of the coil. By providing a pointer in the database of the coil, the process of associating the coil with the comment is executed.

[0010]

[Action]

 The comment transcription process in the cad device of the present invention is preferably executed by the operator selecting and executing the command "comment transcription". The comment information associated with the PC address is provided as, for example, one file (address comment file). The CAD drawing is also prepared as a single file. As its graphic element (graphic database), the output drawing side is provided with a PC address and a coil, and the narrower relay diagram side is provided with coil contacts. . Each of these graphic elements has XY coordinate values to be arranged in the drawing. When the operator selects a comment transcription processing command by menu selection or the like and causes the cad device to execute the command, the cad device searches the coil corresponding to the PC address by the coil retrieval means, and the comment transcription means is retrieved. The process of posting a comment to the coil is executed, and the comment is posted to the part corresponding to the coil in the output diagram.

This comment transcription preferably generates a database of characters relating to the comment, and the comment database is managed as being linked by a pointer from the database side of the coil. This is done so that when an operator desires to post a comment on a coil contact in a relay diagram in a narrow sense, the address comment can be displayed or printed as a comment for the contact.

【Example】

 Hereinafter, the present invention will be described based on examples. FIG. 1 is a functional block diagram showing a control system cad device according to an embodiment of the present invention, which has a comment transcription means. The cad device 10 has a general computer configuration. Preferably, it has a numerical operation processor and is provided with a secondary storage means such as a hard disk or a magneto-optical disk. A keyboard 21 and a digitizer 22 are connected as input devices to the cad device 10, and a display device 30 and a plotter 40 are connected as output devices. The digitizer is shown here as a representative coordinate input device, and an embodiment in which a pointing device such as a so-called mouse is used as a substitute is also possible.

The cad database (DB) 11 is drawing data itself and is stored in a secondary storage means such as a hard disk. The cad DB 11 has a data structure as a database. Individual graphic elements, such as circles, rectangles, straight lines, and character strings, are managed as a graphic database, such as a rectangular DB or a straight line DB, and they indicate the positions to be arranged in the drawing. It is managed as having some XY coordinates. The drawing data stored in the cad DB 11 is output to the display device 30 via the display output means 31, the display device control means 32, the video RAM 33, etc. when the cad is operated. Further, when the operator desires the plotter output, the operator can cause the print output means 41 to output the contents of the card DB 11 to the drawing by operating the digitizer 22 or the like. At that time, the print output means 41 converts the cad DB 11 into plotter drawing command groups according to the XY coordinates of the respective graphic elements, sends the plotter drawing command group to the plotter 40 via the output interface 42, and outputs to paper. Is.

The PC address comment information 12 is, for example, information that is sometimes called an address comment file or the like, and is information that defines the relationship between a PC address and a comment corresponding thereto. This is stored in the PC address comment information storage unit of the secondary storage means such as a hard disk. The comment transcription means 13, the coil search means 14, the drawing means 15 and the like are spatially separated from each other so that the CPU of the computer constituting the cad device 10 reads a necessary program and executes the processing depending on the occasion. They are displayed and their relationships are shown. The selection of these means (commands for command) itself is made by selecting the menu by inputting the menu display means 34 and the digitizer 22 or by inputting the command assignment key from the keyboard 21. It A double arrow is provided on the left side of the menu display means 34 for selecting each command of the cad device (for example, a drawing command represented by the drawing means, a comment transcription command represented by the comment transcription means, etc.) from the menu. This means that the display content of the display means 34 is related to the operation of the digitizer 22 by the operator.

The individual graphic elements that form the cad DB 11 described above are generated and registered by the drawing means 15. Further, the coil search means 14 performs a process of searching for a coil corresponding to the PC address by using the XY coordinates as a clue.

The comment transcribing unit 13 executes a process of transcribing a comment to the coil searched by the coil searching unit 14, and this process generates a character DB relating to the comment and the comment character on the coil DB side. This is a process for providing a pointer that points to the DB.

The cadence device 10 is generally provided with various functions in addition to these means. However, only the portion directly related to the comment transcription is illustrated in FIG.

Hereinafter, a process of transcribing a comment in the control system cad device according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 2 is a diagram showing a comment transfer process by the control system caddy of the present embodiment. FIG. 2A shows a part of the output diagram. FIG. 2B shows a part of the PC address comment information. The PC address comment information shown in FIG. 2 (B) is information stored as, for example, an address comment file, and FIG. 2 (B) shows its contents for convenience. On the other hand, FIG. 2A shows the drawing itself handled by the cad device, that is, the content displayed on the display device during the operation of the cad device or output as a drawing by executing the print command. It should be noted that the broken arrows and are provided for the purpose of explanation, and are not a part of the card drawing.

In FIG. 2A, “Y0000”, “Y0001”, and the like surrounded by a rectangle, and “CR1”, “CR2”, and the like surrounded by a circle are graphic elements of the output diagram, respectively. Thus, each has XY coordinates, and they are arranged in the drawing according to the XY coordinates. Since the cad data has a database structure, the information on each graphic element is also called a graphic DB.

When the cad device of the present embodiment starts the comment transcription processing by the comment transcription means 13, first, the comment processing is performed on “Y0000” at the very beginning, and at that time, as shown in FIG. By referring to the PC address comment information shown, the content of the comment to be transcribed (here, the comment 1, more specifically, the content such as “start start”) is acquired (see FIG. 2A). ). Next, by the processing of the coil search means 14, the corresponding coil is assigned based on the position where “Y0000” is arranged, in other words, the XY coordinates of the DB at the address Y0000, as a clue (see FIG. 2A). reference). Generally, in the input / output diagram, the reference direction is set to the vertical direction or the horizontal direction (in FIG. 2, the horizontal direction). By following the XY coordinates according to the arrangement of the output diagram, the coil corresponding to Y0000, CR1, can be assigned. After that, a comment is assigned to CR1 (see FIG. 2 (A)). This comment allocation is performed by generating a character DB as a graphic element for arranging "Comment 1" in the drawing, and by providing a pointer that points to the character DB from the coil DB side to determine the coil DB and the comment character. It is executed by associating with DB.

This is the end of the comment transfer processing. If only the output diagram of the result of the processing is seen, there is no difference from the conventional example shown in FIG. However, the feature of the present invention is that the transferred comment is associated with the coil, that is, the coil DB and the comment DB are linked by the pointer of the coil side DB. As a result, the advantage shown in FIG. 2 (C) is obtained. FIG. 2C shows a part of the relay diagram other than the input / output diagram in the narrow sense. In FIG. 2C, the coil contact of CR1 is drawn. This relay diagram is generally managed in the same file as the input / output diagram, and is managed on a different page from the input / output diagram. Displaying or printing a comment corresponding to the coil contact shown in FIG. 2C can be performed by a process different from the comment transcription process. This process will now be called "contact comment display" or "contact comment print". When the command of “display comment for contact point” or “print comment for contact point” is executed, the cad device assigns the character DB of the comment by using the pointer provided in the DB of the coil as a clue, and the same character string as that is assigned. The character DB that it has is generated at the position corresponding to the coil contact. As a result, a comment is automatically transcribed corresponding to the coil contact, which was not possible conventionally.

FIG. 3 is a flowchart showing a comment transcription process by the comment transcription means of the cad device according to the present invention. The process starts at step 100 and ends at step 104. Step 101 corresponds to step (A) of FIG. 2, step 102 corresponds to step (A) of FIG. 2 and step 103 corresponds to step (A) of FIG. 2 and has already been described in detail, so the description thereof is omitted here.
