Description

シーケンスプログラム表示装置、及びシーケンスプログラム表示方法Sequence program display device and sequence program display method
　本発明は、シーケンスプログラム表示装置、及びシーケンスプログラム表示方法に関する。 The present invention relates to a sequence program display device and a sequence program display method.
　シーケンスプログラムを作成する際やデバッグを行う際、信号や変数等をシーケンスプログラムから検索することがある。
　シーケンスプログラムから信号等を検索する際、検索要素として信号やシンボル、文字列等が指定される。
　例えば、データ構造情報をデータベースとして有し、構造化されたデータを持つアドレス型パラメータに入力された変数にアクセスするときは、データベースよりデータ構造情報を読み込み、データ構造を一覧として表示し、表示された一覧から任意の変数を選択することにより容易にシーケンス命令の任意のパラメータに設定することができる技術が知られている。例えば、特許文献１参照。 When creating or debugging a sequence program, signals, variables, etc. may be searched from the sequence program.
When searching for signals, etc. from a sequence program, signals, symbols, character strings, etc. are specified as search elements.
For example, when accessing a variable input to an address type parameter that has data structure information as a database and has structured data, the data structure information is read from the database, the data structure is displayed as a list, and the data structure is displayed as a list. A technique is known in which an arbitrary parameter of a sequence instruction can be easily set by selecting an arbitrary variable from a list. For example, see Patent Document 1.
国際公開第２００７／１０２３１３号International Publication No. 2007/102313
　しかしながら、シーケンスプログラムの信号は機能毎に異なり、シーケンスプログラム初心者が機能毎に異なる信号を記憶することが困難である。
　図１２は、機能毎に異なる信号の一例を示す図である。
　図１２に示すように、オーバートラベルチェックの機能において、例えば、「オーバトラベル信号　＋方向　第１軸」から「オーバトラベル信号　＋方向　第８軸」の信号それぞれには、信号「Ｇ１１４．０」から信号「Ｇ１１４．７」が割り当てられている。一方、「オーバトラベル信号　－方向　第１軸」から「オーバトラベル信号　－方向　第８軸」の信号それぞれには、信号「Ｇ１１６．０」から「Ｇ１１６．７」が割り当てられている。
　また、モード選択の機能において、「モード選択信号　ＭＤ１」、「モード選択信号　ＭＤ２」、「モード選択信号　ＭＤ４」、「ＤＮＣ運転選択信号」、「手動レファレンス点復帰選択信号」、及び「インクレメンタル送り選択確認信号」の信号それぞれには、信号「Ｇ４３．０」、信号「Ｇ４３．１」、信号「Ｇ４３．２」、信号「Ｇ４３．５」、信号「Ｇ４３．７」、及び信号「Ｆ３．０」が割り当てられている。また、補助機能において、「完了信号」、「第２補助機能完了信号」、及び「分配完了信号」の信号それぞれには、信号「Ｇ４．３」、信号「Ｇ５．７」、及び信号「Ｆ１．３」が割り当てられている。
　そこで、シーケンスプログラム初心者がシーケンスプログラムから特定の機能の信号を探し出す際、機能と信号の対応表を見たり、シーケンスプログラム内に信号を探しやすいようなコメントを信号毎に入れたりするのは非常に手間がかかる。 However, the signals of the sequence program differ for each function, and it is difficult for beginners of sequence programs to memorize the different signals for each function.
FIG. 12 is a diagram showing an example of signals that differ for each function.
As shown in FIG. 12, in the overtravel check function, for example, each of the signals from "overtravel signal + direction 1st axis" to "overtravel signal + direction 8th axis" Signal "G114.7" is assigned. On the other hand, signals "G116.0" to "G116.7" are assigned to the "overtravel signal -direction 1st axis" to "overtravel signal -direction 8th axis" signals, respectively.
In addition, in the mode selection function, "mode selection signal MD1", "mode selection signal MD2", "mode selection signal MD4", "DNC operation selection signal", "manual reference point return selection signal", and "incremental feed The selection confirmation signal includes a signal "G43.0," a signal "G43.1," a signal "G43.2," a signal "G43.5," a signal "G43.7," and a signal "F3. 0" is assigned. In addition, in the auxiliary function, the signals "completion signal", "second auxiliary function completion signal", and "distribution completion signal" include the signal "G4.3", the signal "G5.7", and the signal "F1", respectively. .3" is assigned.

The control unit 10 includes a CPU, ROM, RAM, CMOS memory, etc., which are configured to be able to communicate with each other via a bus, which are well known to those skilled in the art.
The CPU is a processor that controls the sequence program display device 1 as a whole. The CPU reads the system program and application program stored in the ROM via the bus, and controls the entire sequence program display device 1 according to the system program and application program. Thereby, as shown in FIG. 1, the control section 10 is configured to realize the functions of the search string input section 101, the signal conversion section 102, and the sequence program search section 103. Various data such as temporary calculation data and display data are stored in the RAM. The CMOS memory is backed up by a battery (not shown) and is configured as a nonvolatile memory that maintains its stored state even when the power to the sequence program display device 1 is turned off.
　検索文字列入力部１０１は、例えば、入力装置３０を介してユーザからの入力操作に基づいて、シーケンスプログラムにおいて検索したい信号に関する検索文字列を入力する。
　具体的には、検索文字列入力部１０１は、例えば、シーケンスプログラムの作成、変更やデバッグ等の編集において、入力装置３０を介してユーザから信号の検索指示を受け付けた場合、検索したい信号に関するキーワードを入力する入力画面を表示装置４０に表示する。

　また、検索文字列入力部１０１は、「非常停止」等の１つの検索文字列だけでなく、「非常停止」及び「シリアルスピンドル」等の２つ以上の複数の検索文字列を入力してもよい。
　検索文字列入力部１０１は、入力された検索文字列を後述する信号変換部１０２に出力する。 The search string input unit 101 inputs a search string related to a signal to be searched for in the sequence program, based on an input operation from a user via the input device 30, for example.
Specifically, when the search string input unit 101 receives a signal search instruction from the user via the input device 30 during editing such as creating, changing, or debugging a sequence program, the search string input unit 101 enters a keyword related to the signal to be searched. An input screen for inputting is displayed on the display device 40.
FIG. 3 is a diagram showing an example of the input screen 300.
As shown in FIG. 3, the input screen 300 includes a text box 310 that accepts input of a search string such as "emergency stop" based on a user's input operation via the input device 30. Note that the input screen 300 may include a pull-down menu 310 that allows the user to select a search string instead of the text box 310.

The search string input section 101 outputs the input search string to the signal conversion section 102, which will be described later.
　信号変換部１０２は、入力された検索文字列とデータベース部２０１の信号テーブルとに基づいて信号に変換する。
　具体的に、信号変換部１０２は、例えば、入力された検索文字列「非常停止」を検索キーとしてデータベース部２０１に記憶された図２の信号テーブルを検索し、検索文字列「非常停止」と一致する信号「Ｇ８．４」、「Ｘ８．０」、「Ｘ８．１」、「Ｇ７１．１」、「Ｇ７５．１」～「Ｘ８．４」を抽出する。信号変換部１０２は、抽出した信号「Ｇ８．４」等を変換した信号として後述するシーケンスプログラム検索部１０３に出力する。 The signal conversion unit 102 converts the search string into a signal based on the input search string and the signal table of the database unit 201.
Specifically, the signal conversion unit 102 searches the signal table of FIG. 2 stored in the database unit 201 using, for example, the input search string “emergency stop” as a search key, and converts the input search string “emergency stop” into the signal table shown in FIG. Matching signals "G8.4", "X8.0", "X8.1", "G71.1", "G75.1" to "X8.4" are extracted. The signal conversion unit 102 outputs the extracted signal “G8.4” etc. as a converted signal to the sequence program search unit 103, which will be described later.
　シーケンスプログラム検索部１０３は、信号変換部１０２により変換された信号をシーケンスプログラムから検索する。
　具体的には、シーケンスプログラム検索部１０３は、例えば、シーケンスプログラムの頭から１ネットずつ変換された信号「Ｇ８．４」、「Ｘ８．０」、「Ｘ８．１」、「Ｇ７１．１」、「Ｇ７５．１」～「Ｘ８．４」を検索する。シーケンスプログラム検索部１０３は、信号「Ｇ８．４」、「Ｘ８．０」、「Ｘ８．１」、「Ｇ７１．１」、「Ｇ７５．１」～「Ｘ８．４」のいずれかを含むシーケンスプログラムの箇所（例えば、ネット番号等）を検索する度に、該当箇所を表示装置４０に表示する。
　図４から図７は、変換された信号を含むシーケンスプログラムの箇所の一例を示す図である。図４から図７に示すように、シーケンスプログラム表示装置１は、網掛けで示すように、変換された信号の箇所を赤色や黄色等の色で表示するようにしてもよい。また、シーケンスプログラム表示装置１は、入力装置３０を介してユーザにより検索された信号の箇所が選択されたり、ユーザにより入力装置３０のカーソルやポインタ等の位置が検索された信号の箇所に合わされた場合、当該箇所の信号の補助情報（例えば、「第２機械グループ用」等をポップアップ表示するようにしてもよい。
　そうすることで、ユーザは、機能と信号の対応表を都度見る必要がなくなるとともに、信号を検索しやすいようなコメントをシーケンスプログラムの信号毎に入れる必要がなくなる。
　そして、シーケンスプログラム検索部１０３は、シーケンスプログラムの最後のネットまで検索した場合、表示装置４０に「該当なし」を表示するようにしてもよい。 The sequence program search unit 103 searches for the signal converted by the signal conversion unit 102 from the sequence program.
Specifically, the sequence program search unit 103 searches for signals "G8.4", "X8.0", "X8.1", "G71.1", "G71.1", which are converted one net at a time from the beginning of the sequence program, for example. Search for "G75.1" to "X8.4". The sequence program search unit 103 searches for a sequence program including any one of the signals "G8.4", "X8.0", "X8.1", "G71.1", "G75.1" to "X8.4". Each time a search is made for a location (for example, a net number, etc.), the corresponding location is displayed on the display device 40.
FIGS. 4 to 7 are diagrams showing examples of portions of a sequence program that include converted signals. As shown in FIGS. 4 to 7, the sequence program display device 1 may display the converted signal portions in a color such as red or yellow, as shown by hatching. In addition, the sequence program display device 1 is configured to display a display screen in which a signal location searched by the user is selected via the input device 30, or a cursor, pointer, etc. on the input device 30 is aligned with the location of the signal searched by the user. In this case, auxiliary information for the signal at the relevant location (for example, "for second machine group") may be displayed in a pop-up manner.
By doing so, the user does not need to look at the function-to-signal correspondence table each time, and also eliminates the need to enter comments for each signal in the sequence program to make it easier to search for the signal.
Then, when the sequence program search unit 103 searches up to the last net of the sequence program, it may display "Not applicable" on the display device 40.
＜シーケンスプログラム表示装置１の表示処理＞

Next, the flow of display processing of the sequence program display device 1 will be explained with reference to FIG.
FIG. 8 is a flowchart illustrating display processing of the sequence program display device 1. The flow shown here is repeatedly executed every time the user inputs a search string.

　ステップＳ１２において、ステップＳ１１で入力された検索文字列とデータベース部２０１の信号テーブルとに基づいて信号に変換する。 In step S12, it is converted into a signal based on the search character string input in step S11 and the signal table in the database section 201.
　ステップＳ１３において、シーケンスプログラム検索部１０３は、ステップＳ１２で変換された信号をシーケンスプログラムから検索する。 In step S13, the sequence program search unit 103 searches the sequence program for the signal converted in step S12.
　ステップＳ１４において、シーケンスプログラム検索部１０３は、ステップ１３でシーケンスプログラムからステップＳ１２で変換された信号を検索し発見できたか否かを判断する。発見できた場合、処理はステップ１５に進む。一方、発見できなかった場合、シーケンスプログラム表示装置１は表示処理を終了する。 In step S14, the sequence program search unit 103 searches for the signal converted in step S12 from the sequence program in step 13 and determines whether it was found. If found, the process proceeds to step 15. On the other hand, if it is not found, the sequence program display device 1 ends the display process.
　ステップＳ１５において、シーケンスプログラム検索部１０３は、ステップＳ１３で検索した信号を含むシーケンスプログラムの箇所を表示装置４０に表示し、ステップ１３に戻る。 In step S15, the sequence program search unit 103 displays the part of the sequence program that includes the signal searched in step S13 on the display device 40, and returns to step S13.
　以上のように、第１実施形態に係るシーケンスプログラム表示装置１は、予め信号毎に関連する日本語や英語、シンボル情報等が割り付けられた信号テーブルをデータベース部２０１に記憶し、入力装置３０を介してユーザからの入力操作に基づいて、信号に関する検索文字列を入力し、入力された検索文字列とデータベース部２０１の信号テーブルとに基づいて信号に変換する。シーケンスプログラム表示装置１は、変換された信号をシーケンスプログラムから検索し、検索した信号を含むシーケンスプログラムの箇所を表示装置４０に順次表示する。これにより、シーケンスプログラム表示装置１は、シーケンスプログラム初心者であっても、機能毎の信号を記憶することなく、所望の信号をシーケンスプログラムから容易に見つけ出すことができる。
　また、ユーザは、機能と信号の対応表を都度見る必要がなくなるとともに、信号を検索しやすいようなコメントをシーケンスプログラムの信号毎に入れる必要がなくなる。
　以上、第１実施形態について説明した。 As described above, the sequence program display device 1 according to the first embodiment stores in the database unit 201 in advance a signal table in which Japanese, English, symbol information, etc. related to each signal is assigned, and the input device 30 A search character string related to a signal is inputted based on an input operation from the user via the user interface, and is converted into a signal based on the inputted search character string and the signal table in the database unit 201.
