Abstract

PURPOSE:To make a program module reusable so as to improve the productivity and maintenance service of this device by allowing the memory address of the information of a program to be the absolute value in the form of a load module. CONSTITUTION:This device is provided with an application program processing section 11, module information fetching processing section 12, basic module registering section 13, module editing section 14, and combined module registering section 15. When program parts are prepared, the information of the program is divided into an input, internal and output sections and the memory address of the information is made to be absolute value according to a fixed rule, then, the loading address is set at a fixed value. In addition, when the information is registered as the program parts, the information is registered after signal names are respectively imparted corresponding to the memory addresses of the input, internal, and output so that the signal names can be converted into the same absolute address when the information is delivered and received between other parts. Therefore, the software productivity of this device can be improved, since a program can be assembled hierarchically by collecting several program parts into one new parts.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a program creation device that uses a plant controller to create a program for use in plant equipment that performs direct digital control.

[Conventional technology]

Conventionally, by defining a fixed program pattern as a program part, the program text can be automatically expanded just by referring to this program part (source program), which can save input work. , for example, is known from Japanese Patent Laid-Open No. 62-1.28335.

[Problem that the invention seeks to solve]

The above conventional technology is a general batch processing software.
We believe that this function is sufficient from the perspective of improving productivity. This is because each program section is closed as one process. Direct digital control, which controls plant equipment, has different specifications for each plant, and in order to achieve this, hundreds of program parts must be assembled into one real-time processing program. In conventional technology, 1)
In general, the programming console of a plant controller uses input, that is, machine language, and there is no intermediate language state, so there is no concept of program parts, and parts cannot be combined, so multiple program parts are combined into one. The program cannot do it automatically.

2) Memory absolute addressing and connection of signals between program parts cannot be automatically performed.

3) As systems become larger, the amount of programs is increasing, and with a unified program structure, program management is not possible and layering is necessary. However, it is possible to create new parts by combining several program parts. There was a problem in that it was not possible to register as a program and assemble programs hierarchically.

An object of the present invention is to provide a program creation device that can solve these problems and improve the software productivity of a plant controller.

[Means for resolving issues]

In order to generate a program, module registration is provided, an information input processing section necessary for generating an absorption program from the man-machine section is provided, and the module is then taken out and the module edited.

In order to combine multiple program parts for the above purpose into one real-time processing program, when creating a program part, distinguish program information into input, internal, and output, and store that information according to certain rules. By converting the address into an absolute value and also setting the loading address of the program to a constant value, it is easy to automatically change the memory address and loading address for the actual plant when the program is combined later. In addition, in order to automatically connect signals between each program part, when registering as a program part, signal names are added and registered corresponding to each input, internal/output memory address, and connections between other parts are added. The amount of information is automatically transferred to the same absolute memory address by matching the signal names.

Furthermore, in order to combine some of the smallest program parts into a larger program part, in addition to the storage part that stores the program parts, the identification code of the program parts used in the large program part and the program of the part are stored. A storage unit is provided to store information on how to arrange the above parts and how to connect information between each part as information of a large program part. That is, for the smallest program component, the component code, each signal name, and machine language are the substance of the program component, and the large program component is the module code, arrangement, and connection information that constitute it. It is characterized by the fact that there is no machine language as a large program component, and only the information that elicits the machine language is memorized.

[Effect]

The reason why program information is divided into three categories, input, internal, and output, and converted into absolute addresses in the form of load modules is to facilitate automation when re-addressing memory addresses. The reason for this is that the internal and output memories can be uniquely determined, but the input memory is the output memory of another module. Therefore, the addresses of the input memories cannot be determined until the output memories of all modules have been addressed, so they are managed separately. The reason why the start address of each program component is kept constant is to make it easy to automatically change the loading address of the program component. Furthermore, when performing hierarchical programming, the hierarchical information of the program is not a load module, but information that extracts the program to be hierarchically created, that is, program code, arrangement information, and connection information. This makes it possible to realize multiple hierarchies.

In this way, by standardizing the loading start address and memory address of program modules, when assembling multiple modules into 10 programs,
It becomes possible to easily change the address of each module.

〔Example〕

An embodiment of the present invention will be shown using FIGS. 1 to 4. FIG. FIG. 1 shows the overall configuration. The feature of the present invention is that the basic module of a program is programmed according to certain rules, it is registered in advance in the module editing device 10 which is the main body using the tool 2, and the program is created using this basic module. Therefore, the information that forms the framework of the program and the input signals for each module are defined and created. Here, 1 is a device for inputting and displaying information for creating a program, that is, codes of program modules to be used, module arrangement, and inter-module connection information.

From here, define the framework of the program, that is, the arrangement, and the input information for each module. This information is input to the application program processing section 11 and is managed separately into module arrangement information and module connection information. These pieces of information are passed to the module information retrieval processing section 12, which retrieves modules necessary for program generation from the basic module registration section 13, and arranges the modules according to the arrangement information. As a result, the module editing section 14 first arranges the modules, addresses each module based on the program capacity of each module, and at the same time changes the input memory address of each module to the output memory of another module according to the module connection information. . The basis of the present invention is that the input signal of a module is always an 8-power signal of another module. Further, in the combination module registration section 15, information is registered when a plurality of basic modules registered in the module 13 are combined and used as one module. Information is input here using the first terminal device. The necessary information includes the codes of the combined modules, the codes of the basic modules used therein, and information on their arrangement and connection relationships. That is, said 15
Among them, the code N of the basic module existing in the module registered as a combination module.

It contains information on their arrangement and inter-module signals, and does not contain the actual program. When actually creating a program, if you input the code island of the combined module from 1, it will be determined in 12 that it is a combination module, and the information on the combined module will be extracted from 15. The basic module is taken out and information on the arrangement and connection of the modules is passed to 14 for editing the module.

How a program is edited will be explained with reference to FIGS. 2 to 4.

FIG. 2 shows the flow of 14 module editing processes. Figure 3 shows how the start address of each module changes depending on the loading start address information determined in 14b, and Figure 4 shows how the start address of each module changes depending on the memory address change information determined in 14c to 14e. Indicates whether the memory address changes.

The processing flow of the module editing section 14 will be explained with reference to FIG.

First, the program/module arrangement of the program module 14a is determined by the module arrangement information inputted from the input terminal 1, that is, the consistent number that determines the arrangement of the modules. Next 1
The start address of each module in 4b (this is a constant /4
000, that is, address 4000 in hexadecimal. )
The program module start address information is determined based on the and capacity. Regarding memory address, first 14
The output memory address of c is determined, and the internal memory address information of 14d is determined by addressing in order from the youngest module according to the arrangement of modules. When the output memory is allocated, the internal memory is further allocated to an empty area after the outer memory. The input memory address information of 14e is determined by the linkage with the output memory. The input memory sets the already allocated output memory address as the input memory address of the corresponding module based on the connection information of each module inputted in the application information, that is, the information about which module and which output memory is the input. 14
The start address of the f program module and the addresses of each memory are changed, and finally the 14g load module is output.

The method for determining the program module start address will be explained with reference to FIG.

A certain process has four modules, module A.

A case where the circuit is configured by B, C, and D will be explained as an example.

Module A20 is /4000 to /401F.

Module B21 is registered as /4000 to /402F, module C22 is registered as /4000 to /401F, module D23 is registered as /4000 to /403F, and modules are arranged in the order of A, B, C, and D by module editing processing. The first address is determined according to the capacity of the special number module.

In this example, module A is 740, as shown at 30.
00~/401F, module B is /4020~/40
4F, module C is /4050~/406F, module-7L/D is /4070~/40AF.

A method for determining memory addresses will be explained with reference to FIG. Before editing the module, enter M2O3 for each module.
Therefore, the output is taken from M2O3. In this example,
Input signal a of module A is M2O3, b is M2O3,
c is M2O3, output signal d is M2O3, e is M2O3,
f is M2O3°g is M2O3. Modules B and C are also arranged as shown in FIG.

After editing the module, module A,
B, C in order, and M in order from output memory power 5xoo1
Allocated up to OO7. Next, input memory is signal name a
The linkage is taken by s be CV es gt d, respectively MOOS, MOO6, MOO7゜MOO2,
