JPH09330107A - Comment adding method of ladder chart generation cad system for programmable controller - Google Patents

Abstract

PROBLEM TO BE SOLVED: To eliminate the need to reinput and recorrect comments by inputting addresses and comments to a drawing on a hard sequence CAD side and generating a comment file for registration to a sequencer CAD. SOLUTION: A drawing number and a page number of a hard sequence(H/S) are accepted. When there are comment data on the H/S side, a comment <TAB> comment key is set and the data are added to an input table. When there are the input data of the comment key, a drawing number and a page number are taken out of the input table and H/S drawing data are read in and set in a memory. When there is comment information, the input data are extracted, a comment key is set, and the comment key of an address part corresponding to the comment key of a comment part is retrieved and written in a table for associative data generation while replacing an address <TAB> comment (Chinese character data). Then the table is sorted and its contents are set in an output file.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of giving a signal explanation (comment) to an address number in a ladder diagram generation CAD system for a programmable controller (PC).

[0002]

2. Description of the Related Art As shown in FIG. 6, a ladder diagram C for PC is prepared.
In the AD system, the designer inputs the sequencer application program AP created on the desk to the soft sequence CAD system SCA, and after correcting it here, also inputs the operation explanation (referred to as signal explanation or comment) for each address. To do. In the soft sequence CAD system SCA, a drawing is automatically created based on these pieces of information, and the drawing OT with signal explanation and reference information is output from the plotter.

In FIG. 6, the program part of the soft sequence CAD system SCA is input by an operator who reads a ladder circuit into a Boolean algebraic expression based on a rough sketch created by a designer. In the figure, numbers such as "00001" indicate address numbers, symbols A and B indicate contact shapes, and symbol E indicates output. After the input, when the circuit is changed, the Boolean algebraic expression is changed.

Next, the signal explanation part is input by the operator based on the rough sketch created by the designer, as shown in FIG. In most cases, input using word processing software such as a personal computer. The result (file) is taken into the sequencer CAD system and registered as a database with the address as a key. At the time of this input, the comment reading function of the CAD system extracts address numbers and comments delimited by <TAB> (positions at fixed intervals in the line) and aligns them with the data using the address as a key. All comments already registered can be deleted and re-registered by specifying.

[0005]

The above-described PC application program replaces the signal of the controlled device with each address on the memory of the sequencer CAD system and develops it into the control logic by software. Therefore, as an expanded connection diagram, as shown in FIG.
It consists of a drawing (software sequence diagram) of the application program part and a circuit diagram (hard sequence diagram) in which the controlled device is connected to the memory of the sequencer via various interfaces. The hard sequence diagram is created by a dedicated CAD system (hard sequence CAD system) as shown in FIG. 1 described later, and the soft sequence diagram is created by a dedicated CAD system (sequencer C).
AD system).

In the hardware sequence diagram, a circuit diagram for inputting / outputting to / from the interface printed board of the sequencer as shown in FIG. 9 is prepared, and the corresponding address number and its operation explanation (filled in the item column) in the diagram. Content) is described.

As described above, a CAD system for creating a hard sequence diagram and a CAD system for creating a soft sequence diagram
Since the systems are separate systems, it is necessary to input the comment for the address in each CAD system, which causes a problem in that it takes a lot of time and labor for work. Further, even when the content of the comment is changed or the address number is changed, it is necessary to input it in each CAD system, and there is a problem that the work is troublesome as in the above.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a comment adding method in a ladder diagram creation CAD system for a PC which does not require re-input or re-correction of a comment. .

[0009]

According to the present invention, in order to achieve the above-mentioned object, after receiving the drawing number and the number of pages of a hard sequence, there is input data of a comment in each drawing data. If there is input data as a result of the determination, read the hard sequence data from the input table, set it in the memory, and then determine whether there is comment information in the drawing data of the hard sequence. When there is information, after extracting the input data, set the comment key, search the comment key of the address part corresponding to the comment key of the comment part, and replace the address <TAB> comment (Kanji data to generate interlocked data Write to the table, do it until all the drawing data search processing is completed, and then sort the table And it is characterized in that so as to set its contents to the output file.

Embodiments of the present invention will be described below with reference to the drawings. Figure 1 CAD for ladder diagram creation for PC
In FIG. 1, HS is a hard sequence CAD system used in combination with the system. This hard sequence CAD system HS
The operator inputs various lines, parts drawings, numbers, symbols, comments, signal explanations, and predetermined positions (addresses).
For example, the drawing is drawn on the CRT screen. POT is a plotter output drawing of a hard sequence diagram. A variable called a comment key is input to the hard sequence CAD system HS with respect to the comment information. Here, the comment key is, for example, [A0], [A1], ... [Ann] and [C0], [C1] ... [Cnn] attached to the right shoulder part of each address and item name shown in FIG. It is a code. This comment key employs a means for inputting a comment and a comment key with a symbol “‖” as a delimiter, such as a comment ‖ comment key, when a comment is input to the hard sequence CAD system HS. For example, (0000
Enter as 0‖ [A0]).

When inputting the above comment key, the comment key in the address part: [Ann] (nn is 1 to 99)
Comment key of the comment part: [Cnn] (nn is 1 to 99)
(Consecutive numbers up to). Also, the numbers of nn in the address part and nn in the comment part are made to match.

Thus, for example, when the drawing as shown in FIG. 3 is created, (a) the comment key [A0] at the address is extracted, and (b) the comment key [A0] has: "00".
000 "is extracted, and the comment of (c) address:" 00000 "is extracted with the comment having the comment key of [C0], and the address number:" 00000 "is extracted.
Then, it becomes possible to extract the comment "ON the power receiving circuit breaker".

Hard sequence CAD as described above
Along with inputting various data to the system HS, a comment key is input, the data and the comment key are used to perform the processing of the flowchart shown in FIG. 4 described later, and then the list is output to an output file. By applying this output file to the soft sequence CAD system described above and outputting a soft sequence diagram, a drawing in which signal explanations (comments) are written in predetermined positions can be obtained. In other words, inputting the signal description and address is performed by inputting the signal description and address for which the comment key has been input
It only needs to be entered once in the AD system HS.

Here, the flowchart of FIG. 4 will be described. In FIG. 4, after the setup in step S1, the drawing number of the hard sequence (H / S) and its page number are received in step S2. In step S3, it is determined whether or not the search processing is completed. If not (N), it is determined in step S4 whether or not there is comment data on the H / S side.
If it is (Y), the comment <TAB> comment key is set in step S5, data is added to the input table, and the process returns to step S2. Even if (N) in step S4, the process returns to step S2.

If the process ends in step S3 (Y), the process proceeds to step S5, and it is determined whether there is input data for the comment key. If the determination result is (Y), the process of step S7 is performed. In step S7, the drawing number and the number of pages are extracted from the input table, and the processing range is set. Step S8
Is used to determine the end of the search process, and if not (N),
In step S9, the H / S drawing data is read and set in the memory. After that, in step S10, the drawing data of H / S is extracted, and it is determined in step S11 whether the comment extraction processing is completed. If not (N), whether there is comment information in the determination processing in step S12, Determine whether If the determination result is (N), the process returns to step S8, and if the determination result is (Y), the input data of the comment key is extracted in step S13.
0], incoming power breaker ‖ [C0]). After extraction, the Ann corresponding to the comment key Cnn is searched in step S14, the address of Ann is replaced with Cnn, and the address <TA
B> Generate a comment (Kanji data), step S15
Add processing to the linked data generation table with step S
Returning to step 10, the next drawing data is extracted. If the result is (Y) in step S11, it is determined in step S16 whether or not there is data in the interlocking data generation table.
If the result of the determination is (N), the process returns to step S7 to move to the next drawing number or page processing. If (Y), the process proceeds to step S17. In step S17, the table is sorted, and the table is rearranged in ascending order of [Cn], for example, and then the process returns to step S7 to move to the process of the next drawing number or page. If processing of all drawing numbers and pages is completed (Y) in step S8, the contents of the interlocking data generation table are set in the output file in step S18.

Extending the above function, if the address is set in the first [A0], the address of the comment having the key of [C1] is [[A1] to [A2] Address of [A0] incremented by 1, [C
The address of the comment having the key of [2] can be calculated as the address of [A0] is incremented by 2.

This result is registered in the sequencer CAD as a signal explanation comment input file to the sequencer CAD.

FIG. 5 shows an input file of comment data for registering the sequencer CAD obtained by the processing of FIG.
"B" of "B00000" represents a bit address, and "00000" represents an address number.

Since the types of interface printed board drawings created by the hard sequence CAD are limited, the drawings containing the address and comment keys are registered in advance as standard, and copied when necessary. To use. In this case, only the address and comment are input, and the comment key is left unchanged.
Normally, only the comment part of the "comment ‖ comment key" is entered.

[0020]

As described above, according to the present invention,
By entering an address and a comment (item name) in the drawing of the interface printed board on the hard sequence CAD side, a comment file for registration in the sequencer CAD is created.
There is an advantage that it is not necessary to manually re-input a comment as the sequencer CAD. Also, when the comment is changed, the comment file for registering in the sequencer CAD is regenerated by changing the comment on the drawing of the interface print board of the hard sequence, and the previously registered part is deleted and newly registered. You can do it,
There is an advantage that the comment need not be manually corrected as the sequencer CAD.
