Description

Detailed Description of the Invention [Objective of the Invention] (Industrial Application Field) The present invention provides a sequence program for a programmable controller suitable for controlling a plant system, etc.
This invention relates to an automatic program generation device that dynamically generates a program.

(Conventional technology) In recent years, in order to improve the productivity of software design, research has been carried out on automatic program generation systems that apply knowledge engineering.
Development is ongoing. Among them, the most popular method is to treat existing programs as software components and automatically search for software components that correspond to the required functionality using rules.
There is a software component search method.

FIG. 5 is a block diagram showing the configuration of a conventional automatic program generation device of this type. In the figure, a requested function 1 defines the function of a software component to be searched for, and is input into the automatic program generation device 10 using a keyboard, a character reading device, or the like. This requested function is converted into internal data used in software component search by the requested function decoding/conversion processing system 2, and is converted into internal data used in the request function internal data storage section 3.
is stored in Based on the data stored in this way, the interpreter 41 in the software component search inference processing system 4 selects software components that match the rules stored in the software component search rule storage section 5 into the software component storage section 6. Search from the program storage unit 61. The searched program is then stored in the internal component program storage section 8, and further converted into a language that is easy for the user or designer to understand by the program conversion/output processing system 9 and output.

Note that the working memory unit 7 has a software component search special use data storage unit 71 therein, and a rule interpreter 41.
When the software component search rule is interpreted and executed, internal data is occasionally written and read.

In this way, the program 8 searched according to the requested function and converted into the actual target language is sent to the program automatic generation device 1.
The zero output is output by some output means such as a CRT or a file.

Note that, depending on the system, the requested function internal data and the requested function take the same format, so some systems do not have the requested function decoding/conversion processing system 2, and some systems do not have the requested function decoding/conversion processing system 2, and the internal program and the program 8 take the same format, so the program conversion/output processing Some do not have Corollary 9.

(Problems to be Solved by the Invention) The conventional automatic program generation device described above generates a sequence program by manually defining functions for the program and required functions that define connections between software components. However, in a typical plant, system specifications of the target system are presented that describe how the equipment and machinery are to be operated, the type of drive device, the type of detector, and the purpose of use.

Therefore, in order to generate a plant system program that satisfies the above system specifications, the designer must separately prepare the above required functions based on the system specifications and considering the overall program configuration. The problem was that the burden was too heavy.

In addition, the above software components include signals that constitute the components,
Since the meaning and combination of data are specifically determined for each purpose of use, the number of software components required to closely match the required functions and software components becomes enormous, and it takes a lot of time to process them. There was also the problem that it required

This invention was made to solve the above problems, and provides an automatic program generation device that can reduce the burden on designers, eliminate the need for software components, and significantly shorten processing time. With the goal.

[Structure of the invention]

(Means for Solving the Problems) The present invention provides individual program creation in which a program with an output request and a program with no output request are created separately based on internal data obtained by converting the required function into a predetermined format. an individual program synthesis pattern generation section that generates a pattern of the basic system of the program to be created depending on the presence or absence of the output request; The present invention is characterized in that it is equipped with a synthesis pattern expansion unit that synthesizes according to the pattern and optimizes the synthesis result, and converts the optimized program into a language that is easy for users to understand and outputs it.

(Function) In this invention, a program with an output request and a program without an output request are created separately based on the input system specifications, and furthermore, the basic system of the program to create these programs is created. In addition to optimizing the synthesis results according to the pattern, the designer no longer needs to prepare required functions separately or have software components, which is the case with conventional equipment, reducing the designer's burden. At the same time, processing time can be significantly shortened.

(Embodiment) FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention, and in the figure, the same reference numerals as in FIG. 5 indicate the same elements. The software component search inference processing system 4, the software component search rule storage section 5, the software component storage section 6, and the working storage section 7 shown in FIG.
and the internal component program storage unit 8, and instead, for programs created according to the required specifications based on internal data, the output is turned on in order to correspond to the specifications with output requirements (hereinafter referred to as the ladder diagram). (referred to as specifications)
and specifications that do not require output (hereinafter referred to as specifications for turning off output to correspond to the ladder diagram). an individual program synthesis pattern generation section 13 that generates a basic system pattern of a program to be executed; and an individual program creation section 1
A synthetic pattern development section 14 is provided which synthesizes the outputs from 2 as a program to be created and executed based on the specifications to turn on and off and the basic pattern of the synthetic pattern generation section 13, and optimizes the synthesized result. It is something that

The operation of this embodiment configured as described above will be explained below with reference to the ladder diagrams of FIGS. 3 and 4.

A sequence program to be created is determined by the request function 1 that defines the program function, and specifications for the program output are passed to the request function decoding/conversion processing system 2 of the automatic program generation device 10a. This required function/conversion processing system 2 decodes the specifications for the program output and converts them into knowledge and language used within the automatic program generation device.

The result is then sent to the request function internal data storage unit 31;
Make yourself remember.

Next, based on the stored results, the individual program creation unit 12 individually creates a program to turn on the output of the program and a program to turn off the output of the program based on the specifications for the program output of the sequence to be created. Create to. A specific example of this program is shown in FIG. 2, where the output coil X is an auxiliary output that turns on the output of the corresponding program, and the output coil Y is an auxiliary output that turns off the corresponding program. Also, a, b, c
t*c2. d is a specification for turning on or off the corresponding program output.

The individual program synthesis pattern generation section 13 holds the corresponding program output coil Z by a coil shown in FIG. It has a basic pattern. This holding means that in the case of a program that is executed repeatedly at regular intervals, such as a programmable controller program, even if "signal X that turns on the output" is off, "signal Y that turns off the output This is because coil Z must not be turned off until `` is turned off.

Next, the synthesis pattern expansion unit 14 synthesizes the programs individually created by the individual program creation unit 12 into one program by replacing the parameters x, y, and z of the individual program synthesis pattern using pool algebra. do. A concrete example of this is as follows.

Of these, substituting equations (1) and (2) into equation (3),
When rearranged, the following equation (4) can be obtained.

Expression (4) can be expressed as a ladder in Figure 4, which is the result of the program determined from the specifications.

Since it is written in the language and knowledge inside the program device synthesized and optimized as described above, the programmable controller or the designer who actually uses it by the program conversion/output processing system 9 Then, the program output 11 is obtained by converting it into a language that is easy for the user to understand.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, a program with an output request and a program without an output request are created separately based on input system specifications, and furthermore, these programs are created. Since the synthesis is performed according to the basic pattern of the program to be executed, and the synthesis results are optimized, the designer does not need to separately prepare required functions or have software components, unlike in conventional equipment. This has the effect of reducing the burden on the person and significantly shortening the processing time.
