Further, when the start/continue button 32 is operated while the processing of the product inspection program is stopped, the processing subsequent to the stopping position is continuously executed. For example, when step S6 is executed and the process is stopped before step S7 is executed, when the start/continue button 32 is operated, steps S7 and S8 are executed.

Abstract
Description
本実施形態の作成支援方法は、製品検査プログラムの作成支援を行う方法である。より詳細には、作成支援方法は、製品検査プログラムの動作確認(デバッグ)を行うために実行される。製品検査プログラムが実際に製品の検査工程で使用される前に、コンピュータシステム上で、作成支援方法により製品検査プログラムの動作確認がされる。ユーザは、動作確認の結果を参照して、製品検査プログラムの欠陥を修正する。
(1)構成
以下、作成支援システム1の構成についてより詳細に説明する。なお、本実施形態では、製品検査プログラムが検査対象の画像に基づいて検査対象を検査する場合を想定して説明する。検査対象は、工場等の設備で製造される製品である。検査対象の製品は特に限定されないが、図1では、製品画像Im1に写った検査対象の製品は、上から見てU字状の部材である。
以下、図1、図3及び図5についてより詳細に説明する。ユーザは、パーソナルコンピュータに接続したマウスを操作して、図1、図3及び図5に表示される画像の所定の位置にマウスカーソルを合わせてクリック操作等を行うことにより、作成支援システム1に作成支援方法を実行させる。図1に示すように、表示部14に表示される画像は、ウィンドウ3~8を含む。なお、図1、図3及び図5は、作成支援方法を実行するためのユーザインタフェースの一例であって、例えば、各種の釦の配置及び表記されている文字等の態様は、図1、図3及び図5の態様に限定されない。
次に、作成支援方法により製品検査プログラムの動作確認(デバッグ)を行う場合の処理の流れの一例について説明する。
まず、ユーザは、作成支援システム1が実装されたパーソナルコンピュータを操作して、製品検査プログラムを作成する。作成支援システム1は、プログラムの記述方法についての知識を持たないユーザであっても製品検査プログラムを作成できるように構成されている。より詳細には、ユーザは、予め用意された複数の処理(チップ及びブロック)を組み合わせて、製品検査プログラムを作成する。すなわち、本実施形態の作成支援方法は、予め用意された複数の処理を組み合わせて製品検査プログラムを作成する処理を更に有する。より詳細には、本実施形態の作成支援方法は、予め用意された複数のブロック(及びチップ)を組み合わせて製品検査プログラムを作成する処理を有する。複数のブロックの各々は、チップを複数含み、チップは、ステップインにおける処理の単位である。チップは、1以上のコードからなる。チップを一般的なプログラムコードに置き換えるとすると、チップは1行以上のコードに相当する。チップは、1以上のサブルーチンを含んでいてもよい。例えば、コードが比較的短い処理はチップとして定義されており、コードが比較的長い処理はブロックとして定義されている。
ユーザは、以上のように製品検査プログラムを作成した後、テスト用データを入力として実行部112(図2参照)に製品検査プログラムを実行させ、デバッグする。これについて、図1、図2を参照して説明する。なお、図2に示すフローチャートは、本開示に係る実行部112による処理の一例を示しているに過ぎず、処理の順序が適宜変更されてもよいし、処理が適宜追加又は省略されてもよい。
ステップイン釦34が操作(クリック)されると、ステップインが実行される。ステップインでは、チップを単位として処理が行われる。つまり、作成支援方法における実行処理は、ステップインを含み、ステップインでは、製品検査プログラムの処理を1チップ実行すると製品検査プログラムの実行を停止する。
また、ステップオーバー釦35が操作(クリック)されると、ステップオーバーが実行される。ステップオーバーでは、ブロックを単位として処理が行われる。つまり、作成支援方法における実行処理は、ステップオーバーを含み、製品検査プログラムの次の処理がブロックの冒頭の処理である状態でステップオーバーが実行されると、ブロックを抜けるまで処理を続けて実行し、ブロックは、2単位(つまり、2チップ)以上の処理を含む。
また、ステップアウト釦36が操作(クリック)されると、ステップアウトが実行される。ステップアウトでは、ブロックを抜けるまで処理が続けて実行される。つまり、作成支援方法における実行処理は、ブロックの実行中に、ブロックを抜けるまで処理を続けて実行するステップアウトを含み、ブロックは、製品検査プログラムの2単位(つまり、2チップ)以上の処理を含む。
また、開始/続行釦32が操作(クリック)されると、製品検査プログラムが終了するか、ブレークポイントに到達するまで、処理が続けて実行される。例えば、ブレークポイントが設定されておらず、かつ、製品検査プログラムをまだ開始していないときに開始/続行釦32が操作されると、ステップS1~S3が実行され、ステップS4又はS5が実行され、ステップS6~S8が実行される。また、製品検査プログラムの処理が停止しているときに開始/続行釦32が操作されると、停止位置の後続の処理が続けて実行される。例えば、ステップS6を実行し、ステップS7を実行する前に、処理が停止している場合は、開始/続行釦32が操作されると、ステップS7、S8が実行される。
また、製品検査プログラムの非実行時には、ブレークポイントの設定及び解除をすることができる。より詳細には、ブレークポイントの設定/解除釦37が操作(クリック)されると、ブレークポイントの設定/解除が可能なモードに切り替わる。このとき、ウィンドウ5に表示されたブロック又はチップ(ステップS1~S8、S11~S14)の左の空白が操作(クリック)されると、当該ブロック又はチップにブレークポイントが設定される。ブレークポイントが設定されたブロック又はチップには、丸印が付される。例えば、図1では、ステップS5にブレークポイントが設定されたことを表す丸印が、ステップS5の左の空白に表示されている。もう1度同じ操作(クリック)が行われると、当該ブロック又はチップのブレークポイントが解除される。また、全てのブレークポイントの削除釦38が操作(クリック)されると、設定された全てのブレークポイントが解除される。
製品検査プログラムの実行時に、停止釦33が操作(クリック)されると、製品検査プログラムの処理が一時的に停止する。その後、処理を実行するための複数の釦のうちいずれかが操作されると、処理が再開される。処理を実行するための複数の釦は、開始/続行釦32、ステップイン釦34、ステップオーバー釦35、及び、ステップアウト釦36を含む。
製品検査プログラムの処理が当該プログラムの末尾に到達して処理が終了したとき、及び、停止処理により処理が中断したときに、図3に示すように、製品検査に係る各種の変数の値が表示される。“停止処理により処理が中断したとき”とは、例えば、処理がブレークポイントまで進行したとき、ステップインにより1チップの処理が実行されたとき、ステップオーバー又はステップアウトにより1ブロックの処理が実行されたとき、及び、停止釦33が操作されたとき、である。
図1のウィンドウ3の「検査」と記載されたタブ31が操作され、対応するリボンが展開されることで、作成支援システム1のモードは、検査対象を検査するために製品検査プログラムを実行するオペレーションモードとなる。「検査」と記載されたタブ31に対応するリボンは、少なくとも、検査を開始するための釦(開始/続行釦32と同様の機能の釦)を有する。また、当該リボンは、好ましくは、検査を停止するための釦(停止釦33と同様の機能の釦)を有する。
以上説明した作成支援方法、プログラム及び作成支援システム1によれば、製品検査プログラムの停止時に、処理の結果としての変数及び画像等を出力することで、製品検査プログラムの不具合の有無及びその原因を特定しやすくなる。これにより、製品検査プログラムの信頼性を高めることができる。
以下、実施形態の変形例を列挙する。以下の変形例は、適宜組み合わせて実現されてもよい。
以上説明した実施形態等から、以下の態様が開示されている。
