（第１の実施形態）
　以下、第１の実施形態のシーケンスプログラミング支援装置１００について説明する。シーケンスプログラミング支援装置１００は、複数のシーケンスプログラムから、同じ検索要素を含むシーケンスプログラムを検索し、ユーザに提示する。 First Embodiment
The following describes the sequence programming support device 100 according to the first embodiment. The sequence programming support device 100 searches a plurality of sequence programs for sequence programs that include the same search element, and presents the searched programs to a user.
　図１は、シーケンスプログラミング支援装置１００のブロック図である。シーケンスプログラミング支援装置１００は、プログラム選択部１１、検索要素受付部１２、プログラム検索部１３、付加情報抽出部１４、表示処理部１５を備える。
　シーケンスプログラミング支援装置１００は、ＰＣ（パーソナルコンピュータ）、サーバ、携帯端末などの情報処理装置に適用される。また、シーケンスプログラミング支援装置１００は、数値制御装置などの制御装置に適用してもよい。 1 is a block diagram of a sequence programming support device 100. The sequence programming support device 100 includes a program selection unit 11, a search element receiving unit 12, a program search unit 13, an additional information extraction unit 14, and a display processing unit 15.
The sequence programming support device 100 is applied to information processing devices such as PCs (personal computers), servers, mobile terminals, etc. The sequence programming support device 100 may also be applied to control devices such as numerical control devices.
　プログラム選択部１１は、シーケンスプログラムの選択を受け付ける。シーケンスプログラムは、複数選択することができる。選択されたシーケンスプログラムは、検索対象となる。図２は、シーケンスプログラム選択画面の一例である。この画面ではファイルのパスを指定する。パスで指定されたフォルダ「シーケンスプログラム」に含まれる３つのシーケンスプログラムが検索対象となる。シーケンスプログラム選択画面では、フォルダではなく、ファイルを直接指定してもよい。 The program selection unit 11 accepts the selection of a sequence program. Multiple sequence programs can be selected. The selected sequence programs become the search targets. Figure 2 is an example of a sequence program selection screen. On this screen, the file path is specified. The three sequence programs contained in the folder "sequence programs" specified by the path become the search targets. On the sequence program selection screen, a file may be specified directly instead of a folder.
　検索要素受付部１２は、検索要素の入力を受け付ける。検索要素には、アドレス、シンボル名、コメントなどがある。図２のシーケンスプログラム選択画面には、検索要素の入力領域も設けられている。検索要素の入力領域には、アドレス「Ｒ０．０」が入力されている。検索要素は、必ずしもアドレスではなくてもよく、シンボル名、コメントでもよい。 The search element receiving unit 12 receives input of a search element. Search elements include addresses, symbol names, comments, etc. The sequence program selection screen in FIG. 2 also has an input area for search elements. The address "R0.0" is input in the search element input area. The search element does not necessarily have to be an address, but can also be a symbol name or a comment.
　ここで、シーケンスプログラムの構造について説明する。
　シーケンスプログラムは、バイナリデータで保存されている。バイナリデータは、ＰＬＣが解釈可能なデータである。
　シーケンスプログラミング支援装置は、シーケンスプログラムをラダー図で表示する機能を備える。ラダー図は、リレー、タイマ、カウンタなどのシンボルの集合体である。図３は、ラダー図の一例である。ラダー図は、左母線と右母線という垂直の２本母線を水平接続線で接続した構成をしている。水平接続線には、シンボルが配置される。シンボル記号には、入力リレー、出力リレー、タイマ、カウンタ、補助リレーなどがある。
　信号にはアドレスが割り当てられる。信号のアドレスにはシンボル名（信号の名称）を定義することができる。シンボル名およびアドレスの割り当て方は、統一されているわけではなく、シーケンスプログラムごとに異なる場合がある。 Here, the structure of the sequence program will be described.
A sequence program is stored as binary data that can be interpreted by a PLC.
The sequence programming support device has a function for displaying a sequence program in a ladder diagram. A ladder diagram is a collection of symbols such as relays, timers, and counters. Figure 3 shows an example of a ladder diagram. A ladder diagram is configured by connecting two vertical busbars, the left busbar and the right busbar, with a horizontal connection line. Symbols are placed on the horizontal connection line. Symbols include input relays, output relays, timers, counters, and auxiliary relays.
An address is assigned to a signal. A symbolic name (signal name) can be defined for the signal address. The method of assigning symbolic names and addresses is not standardized and may differ for each sequence program.
　シーケンスプログラムには、図４に示すように、プログラム本体と付加情報が含まれる。付加情報には、信号ごとに定義されたコメントと、シンボル名が含まれる。コメントは、信号を説明する情報である。
　シンボル名は、信号の内容を簡単に示す。シンボル名は、命名規則により、使用できる文字コードや文字数に制限がある。コメントは、シンボル情報よりも自由度が高い。図３の例では、「押しボタンスイッチ」、「センサ」、「非常停止ボタン」、「運転ランプ」、「モータ」などのコメントが信号に割り当てられている。コメントおよびシンボル名を参照すると、信号の働きが分かる。 As shown in Fig. 4, a sequence program includes a program body and additional information. The additional information includes comments defined for each signal and symbol names. The comments are information that explains the signals.
Symbol names briefly indicate the contents of a signal. Symbol names are subject to naming rules, which limit the character code and number of characters that can be used. Comments offer more freedom than symbol information. In the example of Figure 3, comments such as "push button switch,""sensor,""emergency stop button,""operationlamp," and "motor" are assigned to signals. By looking at the comments and symbol names, the function of the signal can be understood.
　付加情報抽出部１４は、信号に定義された付加情報、すなわち、シンボル名およびコメントを抽出する。付加情報は、各シーケンスプログラムで個別に定義されている。信号と付加情報の対応関係は、シーケンスプログラムごとに異なる。例えば、図４のシーケンスプログラムＡでは、アドレス「Ｒ０．０」の信号に、シンボル名「ＡＡ０」、コメント「ａａ０」、アドレス「Ｒ０．１」の信号に、シンボル名「ＡＡ１」、コメント「ａａ１」が割り当てられている。シーケンスプログラムＢでは、アドレス「Ｒ０．０」の信号に、シンボル名「ＢＢ０」、コメント「ｂｂ０」、アドレス「Ｒ０．２」の信号に、シンボル名「ＢＢ２」、コメント「ｂｂ２」が割り当てられている。シーケンスプログラムＣでは、アドレス「Ｒ０．０」の信号に、シンボル名「ＣＣ０」、コメント「ｃｃ０」、アドレス「Ｒ０．３」の信号には、シンボル名「ＣＣ３」、コメント「ｃｃ３」が割り当てられている。
　このように、同じアドレス（Ｒ０．０）の信号であってもシーケンスプログラムによって異なるシンボル名とコメントが割り当てられることがある。 The additional information extraction unit 14 extracts additional information defined for a signal, that is, a symbol name and a comment. The additional information is defined individually for each sequence program. The correspondence between the signal and the additional information differs for each sequence program. For example, in the sequence program A in FIG. 4, the signal at the address "R0.0" is assigned the symbol name "AA0" and the comment "aa0", and the signal at the address "R0.1" is assigned the symbol name "AA1" and the comment "aa1". In the sequence program B, the signal at the address "R0.0" is assigned the symbol name "BB0" and the comment "bb0", and the signal at the address "R0.2" is assigned the symbol name "BB2" and the comment "bb2". In the sequence program C, the signal at the address "R0.0" is assigned the symbol name "CC0" and the comment "cc0", and the signal at the address "R0.3" is assigned the symbol name "CC3" and the comment "cc3".
In this way, even signals with the same address (R0.0) may be assigned different symbol names and comments depending on the sequence program.
　表示処理部１５は、検索要素を含むシーケンスプログラムをラダーで表示する。図５は、アドレス「Ｒ０．０」を検索要素としてシーケンスプログラムＡ、シーケンスプログラムＢ、シーケンスプログラムＣを検索した結果である。表示処理部１５は、複数のシーケンスプログラムのうち検索要素「Ｒ０．０」を含む行を抽出し、抽出したシーケンスプログラムをラダー図で表示する。さらに、付加情報抽出部１４が抽出した、付加情報をラダー図に表示させる。図５の例では、各リレーのシンボルの上にアドレス（「Ｒ０．０」等）を表示し、アドレスの上に付加情報を表示している。 The display processing unit 15 displays the sequence program containing the search element in a ladder diagram. Figure 5 shows the results of searching sequence program A, sequence program B, and sequence program C using address "R0.0" as the search element. The display processing unit 15 extracts lines containing the search element "R0.0" from multiple sequence programs, and displays the extracted sequence programs in a ladder diagram. Furthermore, the additional information extracted by the additional information extraction unit 14 is displayed in the ladder diagram. In the example of Figure 5, the address (e.g., "R0.0") is displayed above the symbol of each relay, and the additional information is displayed above the address.
　図５の例では、検索要素が見つかった行に含まれる他の信号についても、アドレスと付加情報を表示する。図５の例では、シーケンスプログラムＡの検索要素「Ｒ０．０」が見つかった行に含まれるアドレス「Ｒ０．１」の信号の付加情報、シーケンスプログラムＢの検索要素「Ｒ０．０」が見つかった行に含まれるアドレス「Ｒ０．２」の信号の付加情報、シーケンスプログラムＣの検索要素「Ｒ０．０」が見つかった行に含まれるアドレス「Ｒ０．３」の信号の付加情報が表示されている。 In the example of Figure 5, the addresses and additional information are also displayed for other signals contained in the line where the search element was found. In the example of Figure 5, additional information is displayed for the signal at address "R0.1" contained in the line where search element "R0.0" of sequence program A was found, additional information for the signal at address "R0.2" contained in the line where search element "R0.0" of sequence program B was found, and additional information for the signal at address "R0.3" contained in the line where search element "R0.0" of sequence program C was found.
　図６を参照してシーケンスプログラミング支援装置１００の動作を説明する。シーケンスプログラミング支援装置１００は、検索対象となるシーケンスプログラムの選択を受け付け（ステップＳ１）、検索要素の入力を受け付ける（ステップＳ２）。なお、ステップＳ１において、シーケンスプログラムは複数選択できる。 The operation of the sequence programming support device 100 will be described with reference to FIG. 6. The sequence programming support device 100 accepts the selection of a sequence program to be searched (step S1) and accepts the input of search elements (step S2). Note that multiple sequence programs can be selected in step S1.
　シーケンスプログラミング支援装置１００は、ステップＳ２で入力されたアドレスまたはシンボル名、コメントを用いて、シーケンスプログラムを検索する（ステップＳ３）。 The sequence programming support device 100 searches for the sequence program using the address, symbol name, and comment entered in step S2 (step S3).
　シーケンスプログラムが検索要素を含む場合（ステップＳ４；Ｙｅｓ）、シーケンスプログラミング支援装置１００は、検索要素を含む行をシーケンスプログラムから読み出す（ステップＳ５）。シーケンスプログラミング支援装置１００は、検索対象のアドレスに対応付けられた付加情報を抽出する（ステップＳ６）。シーケンスプログラムが検索要素を含まない場合（ステップＳ４；Ｎｏ）、ステップＳ６に移行する。 If the sequence program includes a search element (step S4; Yes), the sequence programming support device 100 reads a line including the search element from the sequence program (step S5). The sequence programming support device 100 extracts additional information associated with the address to be searched (step S6). If the sequence program does not include a search element (step S4; No), the process proceeds to step S6.
　シーケンスプログラミング支援装置１００は、ステップＳ１で選択された全てのシーケンスプログラムの検索が完了したか否かを判断する。全てのシーケンスプログラムの検索が完了していない場合（ステップＳ７；Ｎｏ）、ステップＳ３に移行し、次のシーケンスプログラムの検索を行う。
　全てのシーケンスプログラムの検索が完了すると（ステップＳ７；Ｙｅｓ）、シーケンスプログラミング支援装置１００は、検索要素を含むシーケンスプログラムの表示処理を行う（ステップＳ８）。表示処理では、シーケンスプログラムをラダー図に変換し、それぞれのシーケンスプログラムにアドレス、シンボル名、コメントを付して表示させる。 The sequence programming support device 100 judges whether or not the search for all the sequence programs selected in step S1 has been completed. If the search for all the sequence programs has not been completed (step S7; No), the sequence programming support device 100 proceeds to step S3 and searches for the next sequence program.
When the search for all the sequence programs is completed (step S7; Yes), the sequence programming support device 100 performs a display process for the sequence programs including the searched elements (step S8). In the display process, the sequence programs are converted into ladder diagrams, and addresses, symbol names, and comments are added to each sequence program and displayed.
［第２の実施形態］
　第２の実施形態のシーケンスプログラミング支援装置１００では、同じ検索要素に違う情報（アドレス、シンボル名、コメント）が割り当てられた場合、情報の違いを視覚的に表現する。図７の検索結果表示画面では、情報の違いを色で表現している。具体的には、シーケンスプログラムＡの付加情報は黒色、シーケンスプログラムＢの付加情報は赤色、シーケンスプログラムＣの付加情報は緑色で表示する。 Second Embodiment
In the sequence programming support device 100 of the second embodiment, when different information (address, symbol name, comment) is assigned to the same search element, the difference in the information is visually expressed. In the search result display screen of Fig. 7, the difference in the information is expressed by color. Specifically, the additional information of sequence program A is displayed in black, the additional information of sequence program B in red, and the additional information of sequence program C in green.
　なお、検索要素がアドレスであって、同じアドレスに、異なるシンボル名またはコメントが割り当てられている場合、シンボル名またはコメントの違いを視覚的に表現する。また、検索要素がコメントであって、同じコメントに、異なるアドレスまたはシンボル名が割り当てられている場合、アドレスまたはシンボル名の違いを視覚的に表現する。 If the search element is an address and different symbol names or comments are assigned to the same address, the difference in the symbol names or comments is visually represented. Also, if the search element is a comment and different addresses or symbol names are assigned to the same comment, the difference in the addresses or symbol names is visually represented.
［第３の実施形態］
　情報の違いを視覚的に示すのは、検索要素に限定しない。
　図８に示す第３の実施形態のシーケンスプログラミング支援装置１００は、共通点抽出部１６を備える。共通点抽出部１６は、検索要素以外の要素で共通する要素を抽出する。 [Third embodiment]
Visually indicating differences in information is not limited to search elements.
The sequence programming support device 100 of the third embodiment shown in Fig. 8 includes a common point extraction unit 16. The common point extraction unit 16 extracts elements that are common to elements other than the search element.
　例えば、図９において、１行目のシーケンスプログラムには、１つの検索要素「Ｒ００００．０」、３つの要素「Ｒ００５０．０」、「Ｒ０１００．０」、「Ｒ００００．１」が含まれる。２行目のシーケンスプログラムには、１つの検索要素「Ｒ００００．０」と、３つの要素「Ｒ０１０１．０」、「Ｒ００５０．０」、「Ｒ００００．１」が含まれる。３行目のシーケンスプログラムには、１つの検索要素「Ｒ００００．０」と、３つの要素「Ｒ０１０２．０」、「Ｒ００５０．０」、「Ｒ００００．１」が含まれる。 For example, in FIG. 9, the sequence program on the first line includes one search element "R0000.0" and three elements "R0050.0", "R0100.0", and "R0000.1". The sequence program on the second line includes one search element "R0000.0" and three elements "R0101.0", "R0050.0", and "R0000.1". The sequence program on the third line includes one search element "R0000.0" and three elements "R0102.0", "R0050.0", and "R0000.1".
　１行目～３行目のシーケンスプログラムは、全て共通の要素（アドレス）「Ｒ００５０．０」を含む。すなわち、１行目～３行目のシーケンスプログラムには、全て、検索要素「Ｒ００００．０」と要素「Ｒ００５０．０」の組み合わせが存在する。
　しかしながら、１行目～３行目の検索要素「Ｒ００００．０」と要素「Ｒ００５０．０」には、異なるシンボル及びコメントが付加されている。 The sequence programs on lines 1 to 3 all contain a common element (address) "R0050.0." That is, the sequence programs on lines 1 to 3 all contain a combination of the search element "R0000.0" and the element "R0050.0."
However, different symbols and comments are added to the search element "R0000.0" and the element "R0050.0" in the first to third lines.
　具体的には、１行目の検索要素「Ｒ００００．０」にはシンボル「ＡＡ０」、コメント「ａａ０」、要素「Ｒ００５０．０」にはシンボル「ＬＥＤ１」、コメント「機械１」が付加されている。２行目の検索要素「Ｒ００００．０」にはシンボル「ＢＢ０」、コメント「ｂｂ０」、要素「Ｒ００５０．０」にはシンボル「ＬＥＤ２」、コメント「機械２」が付加されている。３行目の検索要素「Ｒ００００．０」にはシンボル「ＣＣ０」、コメント「ｃｃ０」、要素「Ｒ００５０．０」にはシンボル「ＬＥＤ３」、コメント「機械３」が付加されている。 Specifically, the symbol "AA0" and comment "aa0" have been added to the search element "R0000.0" in the first line, and the symbol "LED1" and comment "machine 1" have been added to the element "R0050.0". The symbol "BB0" and comment "bb0" have been added to the search element "R0000.0" in the second line, and the symbol "LED2" and comment "machine 2" have been added to the element "R0050.0". The symbol "CC0" and comment "cc0" have been added to the search element "R0000.0" in the third line, and the symbol "LED3" and comment "machine 3" have been added to the element "R0050.0".
　共通点抽出部１６は、共通する要素に付加された、付加情報の違いを視覚的に表現する。図９の例では、１行目のシンボルとコメントを黒色、２行目のシンボルとコメントを赤色、３行目のシンボルとコメントを緑色で表示する。色付き文字で表示したシンボルとコメントの組み合わせは異なるが、検索要素と要素のアドレスは共通である。
　また、付加情報の異なりを示す方法は、文字色に限定しない。数値、記号を付したり、文字の修飾を変更したりしてもよい。 The common point extraction unit 16 visually expresses the difference in the additional information added to the common elements. In the example of Fig. 9, the symbol and comment on the first line are displayed in black, the symbol and comment on the second line in red, and the symbol and comment on the third line in green. The combinations of the symbols and comments displayed in colored characters are different, but the search element and the address of the element are common.
The method of indicating the difference in additional information is not limited to the text color, but may be to add a numerical value or a symbol, or to change the text decoration.
　以上説明したように、本開示のシーケンスプログラミング支援装置１００によれば、検索要素をキーとして、複数のシーケンスプログラムを一度に検索することができる。シーケンスプログラムは、ラダー図の形式で表示される。ラダー図には、アドレス、シンボル名、コメントが表示される。 As described above, the sequence programming support device 100 disclosed herein can search multiple sequence programs at once using search elements as keys. The sequence programs are displayed in the form of a ladder diagram. The ladder diagram displays addresses, symbol names, and comments.
　アドレスは、アルファベットと数字の組み合わせなので、信号の役割を把握することは難しい。付加情報であるシンボル名の命名規則は、アドレスよりも自由度が高く、内容を把握しやすい。コメントは、さらに自由度が高く、シンボル名よりも内容を把握しやすい。本開示のシーケンスプログラミング支援装置１００は、アドレス、シンボル名、コメントをラダー図に表示することにより、シーケンスプログラムの内容を確認しやすくなる。 Addresses are a combination of letters and numbers, making it difficult to understand the role of a signal. The naming rules for symbol names, which are additional information, offer greater freedom than addresses and make the content easier to understand. Comments offer even greater freedom and make the content easier to understand than symbol names. The sequence programming support device 100 disclosed herein makes it easier to check the contents of a sequence program by displaying addresses, symbol names, and comments on a ladder diagram.
　付加情報は、シーケンスプログラムごとに異なる。同じアドレスの信号でも異なるシンボル名が割り当てられることがあり、同じアドレスの信号でも異なるコメントが割り当てられることもある。本開示のシーケンスプログラミング支援装置１００では、アドレス、シンボル名、コメントなどを検索要素として、複数のシーケンスプログラムを検索し、特定の検索要素と、検索要素に割り当てられたアドレス、シンボル名、コメントをラダーに表示する。シンボル名とコメントは、プログラマが理解しやすい名称を付けるため、シーケンスプログラムごとに異なる場合がある。本開示のシーケンスプログラミング支援装置１００では、シーケンスプログラムごとに定義されたシンボル名やコメントを表示することにより、それぞれのシーケンスプログラムの違いや内容の把握を支援する。 The additional information differs for each sequence program. Different symbol names may be assigned to signals with the same address, and different comments may be assigned to signals with the same address. The sequence programming support device 100 disclosed herein searches multiple sequence programs using addresses, symbol names, comments, etc. as search elements, and displays specific search elements and the addresses, symbol names, and comments assigned to the search elements in the ladder. Symbol names and comments may differ for each sequence program in order to give them names that are easy for programmers to understand. The sequence programming support device 100 disclosed herein displays the symbol names and comments defined for each sequence program, helping programmers understand the differences and contents of each sequence program.
　例えば、プログラミングでは、過去に作成したシーケンスプログラムを利用して新しいシーケンスプログラムを作成することが頻繁に行われるが、複数のシーケンスプログラムを一覧表示しても、アドレスからシーケンスプログラムの内容を確認することは困難である。本開示のシーケンスプログラミング支援装置１００は、シンボル名やコメントなどの付加情報を付してラダーを表示し、複数のシーケンスプログラムの内容の理解を促し、プログラム検索の負担を軽減する。 For example, in programming, it is common to create new sequence programs using previously created sequence programs, but even if multiple sequence programs are displayed in a list, it is difficult to confirm the contents of the sequence programs from their addresses. The sequence programming support device 100 disclosed herein displays ladders with additional information such as symbol names and comments, facilitating understanding of the contents of multiple sequence programs and reducing the burden of searching for programs.
　以下、本開示を適用したシーケンスプログラミング支援装置１００のハードウェア構成について説明する。図１０は、シーケンスプログラミング支援装置１００のハードウェア構成図である。シーケンスプログラミング支援装置１００は、図１０に示すように、シーケンスプログラミング支援装置１００を全体的に制御するＣＰＵ１１１、プログラムやデータを記録するＲＯＭ１１２、一時的にデータを展開するためのＲＡＭ１１３を備え、ＣＰＵ１１１はバスを介してＲＯＭ１１２に記録されたシステムプログラムを読み出し、システムプログラムに従ってシーケンスプログラミング支援処理を実行する。 Below, the hardware configuration of the sequence programming support device 100 to which the present disclosure is applied will be described. FIG. 10 is a hardware configuration diagram of the sequence programming support device 100. As shown in FIG. 10, the sequence programming support device 100 comprises a CPU 111 that controls the entire sequence programming support device 100, a ROM 112 that records programs and data, and a RAM 113 for temporarily expanding data, and the CPU 111 reads out the system program recorded in the ROM 112 via the bus and executes the sequence programming support process in accordance with the system program.
　不揮発性メモリ１１４は、例えば、図示しないバッテリでバックアップされるなどして、シーケンスプログラミング支援装置１００の電源がオフされても記憶状態が保持される。不揮発性メモリ１１４には、インタフェース１１５、１１８、１１９を介して外部装置１２０から読み込まれたプログラムや入力部３０を介して入力されたユーザ操作などの各種データが記憶される。不揮発性メモリ１１４に、本開示のシーケンスプログラミング支援処理を実行するためのプログラムおよびデータを記憶してもよい。また、表示部７０には各種データが表示される。 The non-volatile memory 114 is backed up by, for example, a battery (not shown), and retains its stored state even when the power to the sequence programming support device 100 is turned off. The non-volatile memory 114 stores various data, such as programs read from the external device 120 via the interfaces 115, 118, and 119, and user operations input via the input unit 30. The non-volatile memory 114 may also store programs and data for executing the sequence programming support process of the present disclosure. In addition, the display unit 70 displays various data.
　インタフェース１１５は、シーケンスプログラミング支援装置１００とアダプタ等の外部装置１２０と接続するためのインタフェースである。外部装置１２０側からはプログラムや各種パラメータ等が読み込まれる。 The interface 115 is an interface for connecting the sequence programming support device 100 to an external device 120 such as an adapter. Programs and various parameters are read from the external device 120.

Various additions, substitutions, modifications, partial deletions, etc. are possible to these embodiments without departing from the gist of the present disclosure, or without departing from the gist of the present disclosure derived from the contents described in the claims and their equivalents. These embodiments can also be implemented in combination.
