〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the graphical program pattern creation method of the present invention.

The diagram program pattern creation method of this embodiment includes a command input section 101, a command analysis section 102, a diagram holder creation section 103, a diagram holder holding section 104, a control holder creation section 105, and a control holder holding section 106. , a display section 107, an input section 108, an output section 109, a graphical program pattern holding section 110, and a chain solving section 11.
1 and an input/output device W112.

First, while a diagrammatic program, which is a program structure diagram created by a diagrammatic program editor that visualizes and creates a program, is displayed on the input/output device 112, the command input section 101 inputs a program structure symbol to be patterned. A diagram holder that is a device for managing the position information of a certain graphic symbol and a graphic symbol that can be expanded at that position in place of the graphic symbol, and a device for managing expansion control statements that control the expansion of this graphic holder. In order to create a certain control holder at the position, the holder number, which is a logical number for uniquely identifying it among the holders, is received as a command from the input/output device 112, and the command analysis unit 10
Send to 2.

Then, the command analysis unit 102 determines a holder internal number, which is an internal number for uniquely identifying the holder to be created in the graphical program pattern, from the position information and holder number in the received command, Furthermore, after determining from the holder number whether the holder to be created is a diagram holder or a control holder, if it is a diagram holder, the holder number and holder internal number are sent to the diagram holder creation section 103. In the case of a control holder, the holder number and holder internal number are also sent to the control holder creation unit 105.

Next, the diagram holder creation unit 103 outputs a diagram symbol creation screen to be displayed on the input/output device 112 to the display unit 107,
The input unit 108 facilitates the input of a graphical symbol, inputs the data input from the input/output device 112 through the input unit 108, and creates a graphical symbol. Furthermore, the created graphic symbol is output to the display section 107 and the graphic holder holding section 104.

Next, when the creation of the diagram holder is completed, the holder internal number is set in the identification area of the diagram holder, and then control is first transferred to the output unit 109, and then the holder number and the holder internal number are chain-solved. The information is sent to the section 111.

Similarly, the control holder creation unit 105 uses the input/output device 112
An expansion control statement creation screen to be displayed on the display unit 107 is outputted to the display unit 107 to facilitate the input of the expansion control statement, and the data input to the input/output device 112 is inputted from the input unit 108 to create the expansion control statement. Furthermore, the created expansion control statement is displayed on the display unit 10.
7 and the control holder holding section 106.

Next, when the creation of the control holder is completed, set the holder internal number in the identification area of the control holder, and then
First, control is transferred to the output unit 109, and then the holder number and holder internal number are sent to the chain solving unit 111.6 The output unit 109 receives output instructions from the diagram holder creation unit 103 and the control holder creation unit 105. Then, each of the diagram holders and control holders held in the diagram holder holding unit 104 and the control holder holding unit 106 are output to the diagram program pattern holding unit 110, and the control is returned to the diagram holder creation unit 1.
03 or return to the control holder creation unit 105.

In addition, if the created holder is a diagram holder, the chain solving unit 111 only performs
Set the holder internal number of the selected graphical symbol in the graphical holder related area of the selected graphical symbol, and if it is not the first (second or later) for the selected graphical symbol,
By setting the holder internal number in the diagram holder relation area of the diagram holder immediately before the relevant diagram holder, the diagram holder is associated with the selected diagram symbol.

On the other hand, if the created holder is a control holder, only one exists for the selected graphical symbol, so by setting the holder internal number of the control holder in the control holder related area, The control holder is associated with the graphical symbol created.

FIG. 2 is a flowchart showing an example of the operation when creating a graphical program pattern. The relative position from the beginning of the graphical symbol to be patterned in the graphical program that is the basis for creating the graphical program pattern (e.g. line number) and the holder number to be created (e.g. a 1-character serial number in the case of a graphical holder) In the case of a control holder, receive A) from the input device (step 201), determine the holder internal number (for example, line number, holder number) (step 202),
Next, when creating a diagram holder from the holder number (YE
In step S), the control is transferred to step 204, and if a control holder is to be created (NO), the control is transferred to step 208.

In step 204, an edit screen for creating a graphic holder is displayed on the input/output device, and input of graphic symbols is requested from the input/output device 112 until the creation of the graphic holder is completed.
Create a diagram holder (step 205). When the diagram holder creation is completed (YES), step 205
7 (step 206). In step 207, a holder internal number is set in the identification area of the created diagram holder, and a diagram holder related to the diagram holder in question does not exist in the diagram holder related area at that time. A value indicating (for example, 0) is set, and control is transferred to step 212.

Similarly, in step 208, an edit screen for creating a control holder is displayed on the input/output device 112, and expansion control statements are input to the input/output device 112 until the creation of the control holder is completed.
12 to create a control holder (step 20
9) When the creation of the control holder is completed (YES), control is transferred to step 211 (step 210). In step 211, a holder internal number is set in the identification area of the created control holder, and control is transferred to step 212.

In step 212, the created graphic holder or control holder is output to the graphic program pattern holding section, and then control is transferred to step 213. In step 213, it is determined whether the created holder is a control holder or the first graphic holder for the selected graphic symbol, and if this condition is met (YES), control is transferred to step 214, and if it is not matched (NO). ), control is transferred to step 215.

In step 214, when the created holder is a diagram holder, the holder internal number of the created diagram holder is set in the diagram holder related area of the selected diagram symbol, and
When the created control holder is a control holder, the holder internal number of the created control holder is set in the control holder relationship area of the graphical symbol to establish a relationship between each holder from the selected graphical symbol.

On the other hand, in step 215, after finding the holder internal number of the diagram holder immediately before the created diagram holder, the holder internal number of the created diagram holder is set in the diagram holder related area of the diagram holder (step 216). ), the relationship between the graphical holders for the selected graphical symbol is established.

FIG. 3 is a holder explanatory diagram showing an example of the relationship between the diagram holder and the control holder.

Figure 3 shows that there are three diagram holders for a diagram symbol, and when the value of the parameter &A is 1, the first diagram holder is expanded, when it is 2, the second diagram holder is expanded, and then , other than 1 and 2, the third diagram holder is expanded, but the contents of the third diagram holder are N0.
It's NE', so I'm afraid nothing will develop.
