Description

[Detailed Description of the Invention] [Industrial Application Field] This invention aims to reduce errors when creating software 91 files, shorten software production time, and shorten program capacity when creating ladder diagrams. It is related to.

[Conventional technology]

Figure 5 is a system configuration diagram showing a conventional circuit diversion method. In Figure 9, (1) is a sequence program creation device, and (2) is a 70-tip disk device.

13) ij70tubi, (4) is a programmable controller, +51i is a cable that connects (1) and (4).

Next, the operation will be explained.

The method of reusing the program (ladder diagram) is to create a basic program using the sequence program creation device (1), and register the program created using the 70T disk device (2)K to the 70T (3).

Read the registered sequence program from the floppy disk (3) again from the 70 disk drive (2).

Register in the sequence program creation device (1). 7a
If the basic sequence program creation device is read from TSP (3), the basic sequence commands.

A diverted circuit is created by inputting data commands, output numbers, data numbers, etc. from a sequence program creation device.

Problems that the c-based BA is trying to solve] Conventional sequence program creation devices are configured in more than one manner, so when creating a 7-to-que 7 table, the same circuit must be entered in several places.

There was a problem in that the production time of the software was significantly increased and the capacity of the drive male and Y-1 Yence programs increased.

This invention was made to solve the above-mentioned problems, and it is a sequence control that can reduce the capacity of the programmable controller's 7-channel controller, shorten software production time, and reduce software production errors. The purpose is to obtain macro instructions in .

[Tasks, means to decide the problem]

This departure F! Sequence control related to J4 is 1 macro instruction
11, a basic program for macro instructions is created, and this basic program is created using only symbols such as sequence instructions and data instructions. Further, in the macro instruction, only the name of each symbol is set.

[Effect]

In sequence control, the name of each symbol is defined in the macro instruction, and each time the programmable controller executes the macro instruction, the programmable controller executes the basic program based on the name of each signal defined in the macro instruction. The macro command is executed based on the name of each signal defined by the macro command.

〔Example〕

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

In FIGS. 1 and 2, (1), (4), and (5) are completely the same as the conventional device described above. (6) shows the method of controlling macro instructions, and only sets the names of each symbol of the basic program. (7) is an example of a basic program, and 9. (8)
is a program that runs when a programmable controller executes a macro instruction.

Next, the effect will be explained.

For macro commands in sequence control, the names of each symbol defined in the basic program are input. In addition, the basic program for macro instructions is a sequence program created using only symbols.

When executing this macro instruction in the programmable controller, the programmable controller applies the name of each symbol defined by the macro instruction to the base 4 of the basic program.At this time, the execution program is as shown in ()) in Fig. 2. is converted to □ra' (8)
Since the macro instruction is not executed, the decommissioning circuit ())
becomes the circuit. □ Next, this invention will be explained using a 70-chart.

In Figure 3, the sequence program creation device (
Create a ladder diagram in part 9), and create part 61 - macro program and basic program t-fli'. Then, use the part aD to convert the i-chrome command into a language for the programmer controller, and use the converted language in step 7 of (4).
'0/Ramable controller K (1:) is written to the sequence program creation device to operate the programmable controller (4).

Do not convert the basic program to normal ladder 1 using as, write it using the sequence program creation device in (1),
(4) When the programmable controller executes the macro instruction in the part number a, the macro instruction is expanded into a basic program. In the part □, the basic program is expanded into a control code for the programmable controller on the macro instruction.The part ``b4ae'' is executed using the instruction code expanded into the control code □ for the programmable controller. (In the 17+ minute, the control code that has been executed at a certain point is returned to the light.

In this way, when creating a program for a programmable controller, if there are identical 14 grams, frequent use of the □ macro command □ will save time during shiftware production and avoid input errors at that time. In addition, the capacity of the sequence may be reduced by 10 grams.

By the way, in the above explanation, when considering the reduction of sequence 10 grams using macro instructions, is 9 changed to 0ALL or another instruction code?
There is no need to ask for something that can be achieved.
- [Effects of the Invention] As described above, according to the present invention, since it is configured as described above, the following effects are achieved.

Large-scale systems are often configured with the same functions, and in this case KF! Since there are a large number of identical circuits, the use of macro instructions has the effect of shortening the time required to produce the circuit, shortening the time required to start up the system, and reducing the capacity of the sequence program.
