Abstract

PROBLEM TO BE SOLVED: To prevent time for program design from becoming long. SOLUTION: The program in a ladder form for a programmable controller and the program in a text form are mutually converted by replacing the information of the text form and the information of the ladder form.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program conversion method for performing programming or the like for operating a programmable controller.

[0002]

2. Description of the Related Art Hitherto, a ladder-type program for operating a programmable controller has been created by a dedicated program creating device.

[0003]

In the above-mentioned conventional technology, all program technicians must learn how to use a dedicated program creator, and it takes time to learn how to use the dedicated program creator. For this reason, there was a problem that it took time to design the program.

The present invention has been made in view of the above points, and an object of the present invention is to provide a program conversion apparatus which does not require much time for program design.

[0005]

In order to solve the above-mentioned problem, a method of the present invention according to claim 1 performs a mutual conversion between a ladder format program and a text format program for a programmable controller. This is done by replacing the text information with the ladder information.

According to a second aspect of the present invention, in the method of the first aspect, the text format program converted from the ladder format program is stored in the text format.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. This program conversion method is executed, for example, by inputting a program for the conversion into a personal computer and activating the program.

According to this program conversion method, for example, the ladder format program 1 for the programmable controller shown in FIG. 1A is replaced with text format information from ladder format information. Figure
It can be converted to the text format program 2 shown in (b). The text format program 2 converted from the ladder format program 1 is stored in a text format.

Conversely, by replacing the information in the text format with the information in the ladder format, the program 2 in the text format shown in FIG. It can also be converted to program 1.

[0010] The program conversion by this program conversion method can be performed only by mutual conversion between the ladder program 1 shown in FIG. 1A and the text program 2 shown in FIG. Ladder program 1 shown in Fig. 2 (a), which contains functions other than input and output, and text program 2 shown in Fig. 2 (b).
It can be used for mutual conversion with.

In this program conversion method, the mutual conversion between the ladder format program 1 and the text format program 2 for the programmable controller is performed by replacing the text format information with the ladder format information. Because it is performed by a general-purpose conversion,
It can be performed using, for example, a personal computer instead of a dedicated program creation device, and it is not necessary to learn how to use the dedicated program creation device. Therefore, the program design does not take much time.

Further, since the text format program 2 converted from the ladder format program 1 is stored in a text format, if it is tool software capable of reading data having an extension of “.txt”, ,
It can be opened and has high versatility.

[0013]

According to the first aspect of the present invention, the mutual conversion between the ladder format program and the text format program for the programmable controller is performed by replacing the text format information with the ladder format information. Since the conversion is performed by a general-purpose conversion, the conversion can be performed using a personal computer instead of a dedicated program creating device, for example, and it is not necessary to learn how to use the dedicated program creating device. It does not take much time to learn how to use it, and therefore, it does not take much time to design the program.

According to the second aspect of the present invention, in addition to the effect of the first aspect, a text format program converted from a ladder format program is stored in a text format. If it is tool software that can read data of “txt”, it can be opened and has high versatility.
