Abstract

PURPOSE:To easily execute a copy, a movement and a collation of a part of a program between programs by setting the capacity of a memory for storing the program data to the capacity which can store plural programs. CONSTITUTION:A memory 14a contained in a programming device 2 has the same capacity as that of a memory 5 contained in a digital control apparatus 1, therefore, the contents of the memory 5 are read in advance in the memory 14a in an on-line mode. As a result, even at the time of a local mode, the same programs P1-Pn as those of the memory 5 are stored in the memory 14a, therefore, even in a local mode in which the programming device 2 has been detached from the digital control apparatus 1, a work for copying, moving and collating a part or the whole of a program can be executed easily between plural programs.

The present invention relates to a programming device for creating, modifying, copying, collating, etc. programs used in digital control equipment, and particularly relates to a programming device for digital control equipment that can be used in a local mode.

[Following technique]

FIG. 2 is illustrated in, for example, [Mitsubishi Electric Technical Report J Vol. 54.
N. 12 (December 1980), pages 33 to 37, is a configuration diagram showing a conventional programming device for digital control equipment. In the figure, 1 is a digital control device such as a digital sequence controller, which executes various controls according to programs and data stored in a memory. A programming device 2 is connected to the digital control device 1 and executes programming creation and modification. Here, in the digital control equipment l, 3 is a central processing unit, and a bus 4
Control processing is executed in accordance with the programs and data stored in the memory 5 connected via. 6 is a communication interface that is connected to the path 4 and communicates with the programming device 2 as an external device; 7 and 8 are bus interfaces that mutually exchange various control data between the bus 4 and the bus 9; A process input/output unit 10 is connected to the bus 9 and performs process control and imports process data. In addition, in the programming device 2, 11 operates according to a program stored inside.
A central processing unit that executes program creation processing, 1
A communication interface 2 is connected to the central processing unit 11 via a bus 13, and is connected to a communication interface 6 in the digital control device 1 via an external line. 14 is a memory in which the created program is stored; 15 is a cathode ray tube display (hereinafter referred to as CRT display) used for visual confirmation when inputting a program, modifying a program, etc.
bus 1 via the CRT interface 16.
Connected to 3. A keyboard 17 is used for inputting programs, modifying programs, etc., and is connected to the bus 13 via a keyboard interface 18. A flexible disk driver 19 is used to store created programs, and is connected to the bus 13 via a flexible disk interface 20. FIG. 3 is a block diagram of the memory 5 in the digital control device 1 shown in FIG.
, n types of programs and data D, , D, are stored. FIG. 4 is a block diagram of the memory 14 in the programming device 2 shown in FIG.
It is configured with a small capacity memory that can only store the following information. Next, the operation will be explained. FIG. 5 is a flowchart showing the operation of the programming device 2 in the digital control equipment programming device shown in FIG.
When the programming device 2 starts its operation, the central processing control section 11 determines the connection state with the digital control device 1 as shown in step ST, based on the check program stored therein. When it is confirmed that the communication interface 12 is connected to the communication interface 6 of the digital control device 1 via an external line, it is determined that the connection state is online mode. If the result is YES, the process moves to step STI. In addition, if the communication interface 12 is not connected to the communication interface 6 of the digital control device l, that is, if the external line connecting the communication interface 12 and the communication interface 6 is open, the communication interface 12 can be operated in offline local mode. If it is determined that there is, and the determination result is no, the process moves to step ST3. Here, if the online mode is determined in step STI, the process moves to step ST2 to execute program creation and modification processing. For example, when creating a program, first, by operating the keyboard 17, a command to read the memory 5 provided in the digital control device 1 is given to the central processing control unit 11 via the keyboard interface 18. Central processing control unit 11
When receiving such a subsequent command, the communication interface 12. The content introduction of the memory 5 is transmitted to the central processing control unit 3 of the digital control device l via the external line and the communication interface 12. When the central processing control unit 3 receives the content introduction, it executes the program P detailed in FIG. 3 stored in the memo IJ5. ~ Returns index information for Pm. When the central processing control unit 11 in the programming device 2 receives the index information, it displays the contents on the CRT display 15 via the CRT interface 16. Therefore, the operator specifies the program name necessary for creating the program from the index information displayed on the CRT 15. The specified contents are transmitted from the central processing control section 11 to the central processing control section 3, and the program with the specified contents is read out and transferred to the central processing control section 11. When the central processing control unit 11 receives the transfer program, it first stores it in the memory 14. Here, the memory 14 in the programming group W2 is
As shown in FIG. 4, since its nature is to temporarily store program data, its capacity is small enough to store one type of program data. memory 1
The program data stored in the central processing controller 1
1, the contents are displayed on the CRT display 15 through the CRT interface 16. While scrolling the program data displayed on the CRT display 15, the operator copies and corrects the parts necessary for the next program to be created, and also inputs newly required parts from the keyboard 17. The target program is completed in the memory 14. The program completed in this manner is again transferred to the memory 5 of the digital control device 1 and stored therein under the control of the central processing control section 11 and the central processing control section 30 for use. Furthermore, when a storage command is input from the keyboard 17, a newly created program stored in the memory 14 is stored under the control of the central processing control unit 11.
The data is written to a flexible disk (floppy disk) set in the flexible disk driver 19 via the flexible disk interface 20. Such operations are similar when modifying a program stored in the memory 5 of the digital control device 1. Next, if the determination in step STI is NO and it is determined that the mode is local mode, step STI is executed.
Move to T3. Here, the operator selects the keyboard 17.
When a command for successive execution of the program stored in the memory is input from , the central processing control unit 11 displays the program data stored in the memory 14 as an internal memory on the CRT display 15 since it is in the local mode. . Here, the memory 14 has a small capacity as described above, and is only able to store one type of program data. Therefore, if the currently stored program data is not related to a new program to be created, it becomes necessary to exchange the stored program data. In this case, a flexible disk reading command is input from the keyboard 17. In this way, when a flexible disk reading command is input, the central processing control unit 11 reads the program list recorded on the flexible disk set in the flexible disk drive 19 via the flexible disk interface 20. is first read and displayed on the CRT display 15. Next, when the operator specifies a target program name from the contents of the display list, the central processing control unit 11 retrieves program data matching the specified contents from the flexible disk drive 19 and stores it in the memory 14. , the contents are displayed on the CRT display 15. The operator can perform processing such as copying, modifying, duplicating, and collating only the necessary parts of the display program data, or inputting newly necessary parts. ,
Create a new program. The new program created in this way is stored in the memory 14 as a new program. Further, when a storage command is input from the keyboard 17 as necessary, the central processing control unit 11
is connected to the flexible disk drive 19 via the flexible disk interface 20, and the memory 14
The program data stored in the flexible disk drive 19 is transferred and recorded on the flexible disk stored in the flexible disk drive 19 for storage.

[Problem to be solved by the invention]

Since the conventional programming device for digital control equipment is configured as described above, only one type of program data is stored in the memory 14 in the local mode, and part of the program is copied between programs.
Cannot be moved, copied or compared. To perform such processing, the programming device must be connected to a digital control device and an online mode that utilizes the large capacity memory built into the digital control device must be used. Since the system monopolizes the digital control equipment, there is a problem in that the usage efficiency of the digital control equipment decreases. This invention was made to solve the above-mentioned problems, and without having to exclusively use digital control equipment,
It is an object of the present invention to provide a programming device for digital control equipment that can perform processing such as copying, moving, and collating a part or all of a program between programs.

First, at the start of operation, the central processing control unit built into the programming device performs the same processing as shown in FIG.
Execute processing to determine whether the mode is online mode or local mode. If the online mode is determined, program creation and modification processing is executed in the same manner as in the past. Next, if it is determined that the mode is local mode, the program stored in the memory 14a is read out and new creation, modification, and collation operations are executed. In this case, the memory 14a built in the programming device 2 is
Since it has the same capacity as the memory 5 built into the digital control device 1, the contents of the memory 5 built into the digital control device 1 are read in advance in online mode. Then, even in the local mode, the memory 14a built in the programming device 2 stores a plurality of types of programs P, -P, .

displayed on the T-display 15. The operator issues a copy command to a desired portion of the program displayed on the CRT display 15. When a copy command is input, the central processing control unit 11 inquires about the copy destination of the designated copy range. On the other hand, when the operator specifies program P2, the contents of program P2 are displayed on the CRT display 15. Next, when the operator specifies the copy destination of the previously specified copying portion for the content of the program P2 displayed on the CRT display 15, the central processing control unit 1
In No. 1, the items to be copied are copied to the relevant part to create a single program, and this is stored as a new program or in place of a previously stored program. Such processing is the same when modifying a program, and a new program that has been modified is stored in the memory 1 as a new program or in place of a previously stored program.

In the above embodiment, a case has been described in which the memory 14a is set to have the same capacity as the memory 5 built in the digital control device 3. However, the present invention is not limited to this, and it is possible to store at least a plurality of types of programs. It is fine as long as it can be done. In addition, this memory 14a
, a case has been described in which the contents of the memory 5 built into the digital control device 3 are transferred and stored, but the program to be stored in the memory 14a cannot be transferred from any part of the flexible disk driver 19 or the like. It goes without saying that it is okay to do so. Furthermore, the memory 5 built into the digital control device 3 also stores two types of data: constants and variables, but since there is no need to create variable data, the data is stored in the memory 14a of the programming device 2. If constant data can be stored, all data can be created even without variable data.

Program data can now be read, making it extremely easy to copy, move, and verify part or all of a program between multiple programs, even in local mode where the programming device is separated from the digital control device. You will be able to do this. Furthermore, since the digital control equipment is not used exclusively when creating and modifying programs, the efficiency of using the digital control equipment is also improved.
