2. Description of the Related Art Conventionally, a sequence program executed by a PC (programmable controller) has a format such as a logic description and a ladder diagram, but a flow chart method is used to make it easy to understand the overall flow of work. It is a thing. The flowchart system expresses steps in process units, and a representative example thereof is an SFC (sequential function chart) system. However, even in this flow chart method, a logic description, a ladder diagram, etc. are used as a program of a specific operation in each process.

In the case of managing such a flow chart type sequence program, the program showing the overall flow is a main program, and the program of each step is a sub program, and the creator assigns a file name to each. It is stored in one directory.

[0004]

However, in recent years, the number of subprograms in the flow chart system has become enormous. Therefore, it is very laborious for the creator to manage the file names of all the subprograms and to manage the directories.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a sequence program management system in which each subprogram of a flow chart type sequence program can be easily managed.

[0006]

In order to solve the above problems, the present invention provides a sequence program management system for managing each subprogram of a sequence program represented by a flow chart system, wherein the subprogram Creating / editing means for creating / editing, a file name assigning means for automatically assigning a file name to the created / edited subprogram, and a connection relationship input for inputting a connection relationship of each of the subprograms with the file name There is provided a sequence program management system characterized by comprising: means and directory creating means for automatically creating a directory indicating a connection relationship between the input subprograms.

[0007]

When the subprogram is created and edited by the creating and editing means, the file name assigning means automatically gives the file name to the created and edited subprogram. On the other hand, the connection relation input means inputs the connection relation of each subprogram having a file name. Then, the directory creating means automatically creates a directory indicating the connection relationship of the input subprograms.

Therefore, the directory can be easily created and the subprograms of the sequence program can be easily managed.

After the creation and editing of the subprogram with the file name P300 is completed, the operator operates the menu 1
Select "Child" of 51a. As a result, P31 is set as the file name following the file name P300.
Two file names are set in units of 50, such as 0 and P350. The operators are file names P310, P3
50 is selected to create and edit each item (steps S6 and S7). Then, after the creation and editing of the file name P350 is completed, similarly, “Child” of the menu 151a is displayed.
When is selected, four file names are set in units of 10 such as P360, P370, P380, and P390 as file names following the file name P350. The operator selects the file name P360 from among these to create and edit (step S8).

On the other hand, after the editing of the subprogram of the file name P200 is completed, the file names following the file name P200 are 50, such as P210 and P250.
Two file names are set in units. The operator selects the file name P210 to create and edit (step S5). After that, the file name P210
P220, P230, P as the file names following
Three file names are set in units of 10 such as 240. The operator selects the file name P220 to create and edit it (step S9).

By the above procedure, the SFC type sequence program is created and edited. On the side of the automatic programming device, a management file indicating the relation of each program is created by the directory based on the input data. This file is called a list file here.

FIG. 5 is a diagram showing an example of the list file. Each list file 30 is managed by being given a list file name. This list file 30
In, the execution order of each file name is indicated by the position of the displayed column. Here, the file name P1
Since 00 is displayed at the top and in the leftmost column, the saprogram of the file name P100 is displayed in step S1.
It is shown to be a subprogram of.

The directory \ P100 \ is displayed immediately below the file name P100. This directory \ P ... \ means that the file name shown next is serially connected to the previous file name. That is, here, it is shown that the subprogram having the file name P200 is connected in series next to the subprogram having the file name P100. Also, the file name P20
For 0, the subprograms with file names P300 and 400 are displayed at the same column position. That is, these P200, P300, and P400 are shown to be connected in parallel.

A directory \ P200 \ is displayed below the file name P200, and a file name P210 is displayed below it. This is similar to the above, in the subprogram of the file name P200, the file name P21
It is shown that 0 subprograms are connected in series. Below that, similarly, the file name P
It is shown that the subprogram of file name P220 is connected in series to the subprogram of 210.

Below the file name P300 shown in parallel with the file name P200, the directory \ P300 \ indicates that the file names P310 and P350 are connected in parallel. The directory: P200 is displayed on the right of the file name P310. Directory: P ... indicates which file name subprogram the previously displayed file name subprogram is connected to. Here, the file name P310
It is shown that the sub program of is connected to the sub program of the file name P210.

Similarly, it is shown that the subprogram having the file name P360 is connected to the subprogram having the file name P210, and the subprogram having the file name P400 is connected to the subprogram having the file name P220.

As described above, in this embodiment, the system side automatically creates the file names of the respective subprograms to create the list file 30, so that the work is simplified. Further, in the list file 30, since the directories \ P ... \,: P ... which indicate the connection relationship are used and the connection relationship is also indicated by the column position of each file name, the management is easy. Become.

Furthermore, the sequence created in this way
Even after the program is loaded into the PMC or the like, the file structure at the time of editing can be reproduced from the object based on the information in the list file 30.

In this embodiment, each time the operator inputs a subprogram, the system interprets and creates the list file 30. However, after inputting all the subprograms, the list file 30 is batch-processed. May be created.
