It is assumed that the log records the operation history of the software read from the internal storage 10. An operator loads software from the external storage 20 when an error occurs in the numerical control device 100 or for purposes such as maintenance of the numerical control device 100. Before loading software from the external storage 20, the log analysis unit 14 analyzes the log, determines whether an error occurs in the software when executed from the internal storage 10, and notifies the operation restriction unit 15.
　動作制限部１５は、ログ解析部１４からの通知に基づき、エラーの発生したソフトウェアの動作を制限する。動作制限の１つとして、ソフトウェアの実行の停止がある。また、一旦実行を停止し、ソフトウェアを実行するか否かをユーザに問い合わせてもよい。 The operation restriction unit 15 restricts the operation of the software in which the error has occurred based on the notification from the log analysis unit 14. One of the operational limitations is the suspension of software execution. Alternatively, execution may be temporarily stopped and the user may be asked whether or not to execute the software.
　ローディング部１６は、ストレージ判定部１３の通知に従い、内部ストレージ１０のソフトウェアか外部ストレージ２０のソフトウェアをメモリに展開する。 The loading unit 16 loads the software in the internal storage 10 or the software in the external storage 20 into the memory according to the notification from the storage determining unit 13.
　実行部１７は、動作制限部１５により動作制限されていないソフトウェアを実行する。ソフトウェアの動作には、自動運転、データ入出力、パラメータ設定などがあるが、これに限定されない。 The execution unit 17 executes software whose operation is not restricted by the operation restriction unit 15. Software operations include, but are not limited to, automatic operation, data input/output, and parameter settings.
　図２を参照して第１の開示の数値制御装置１００の動作を説明する。前提として、内部ストレージ１０と、外部ストレージ２０には、ほぼ同じソフトウェアが格納されており、通常動作では、内部ストレージ１０からソフトウェアを読み出す。外部ストレージ２０のソフトウェアは、数値制御装置１００に通常動作を実行させながら、数値制御装置１００の動作をトレースする機能を備える。 The operation of the numerical control device 100 of the first disclosure will be described with reference to FIG. As a premise, almost the same software is stored in the internal storage 10 and the external storage 20, and in normal operation, the software is read from the internal storage 10. The software in the external storage 20 has a function of tracing the operation of the numerical control device 100 while causing the numerical control device 100 to perform normal operations.
　数値制御装置１００は、通常動作において、内部ストレージ１０からソフトウェアをロードする（ステップＳ１）。数値制御装置１００は、内部ストレージ１０からロードしたソフトウェアに従い通常動作を行う。数値制御装置１００は、通常動作において、ログを記録している（ステップＳ２）。 In normal operation, the numerical control device 100 loads software from the internal storage 10 (step S1). The numerical control device 100 performs normal operations according to software loaded from the internal storage 10. The numerical control device 100 records a log during normal operation (step S2).
　数値制御装置１００に外部ストレージ２０が装着される（ステップＳ３）。外部ストレージ２０の装着は、数値制御装置１００のエラー発生時のバックアップ、数値制御装置１００のメンテナンスなどのタイミングで行う。また、ステップＳ３の外部ストレージの装着する前に、数値制御装置１００の電源をＯＦＦし、外部ストレージを装着したのち、数値制御装置１００を起動してもよい。 The external storage 20 is attached to the numerical control device 100 (step S3). The external storage 20 is installed at the timing of backup when an error occurs in the numerical control device 100, maintenance of the numerical control device 100, etc. Further, before installing the external storage in step S3, the power of the numerical control device 100 may be turned off, and after installing the external storage, the numerical control device 100 may be started.
　ユーザは、内部ストレージからソフトウェアをロードするか、外部ストレージ２０からソフトウェアをロードするかを選択する。ユーザが内部ストレージを選択した場合（ステップＳ４；Ｙｅｓ）、数値制御装置１００は、内部ストレージからソフトウェアをロードし（ステップＳ５）、実行する（ステップＳ９）。
ユーザが外部ストレージを選択した場合（ステップＳ４；Ｎｏ）、数値制御装置１００は、外部ストレージ２０からソフトウェアをロードする（ステップＳ６）。外部ストレージ２０からソフトウェアをロードした場合、ステップＳ２で記録したログを確認し、制限する動作を判定する（ステップＳ７）。数値制御装置１００は、ソフトウェアの動作を制限し（ステップＳ８）、実行する（ステップＳ９）。 The user selects whether to load software from internal storage or from external storage 20. If the user selects internal storage (step S4; Yes), the numerical control device 100 loads software from the internal storage (step S5) and executes it (step S9).
If the user selects external storage (step S4; No), the numerical control device 100 loads software from the external storage 20 (step S6). When the software is loaded from the external storage 20, the log recorded in step S2 is checked, and operations to be restricted are determined (step S7). The numerical control device 100 limits the operation of the software (step S8) and executes it (step S9).
　本開示の数値制御装置１００は、外部ストレージ２０からソフトウェアをロードするとき、内部ストレージ１０からソフトウェアを実行したときのログを確認して動作制限事項を決定し、ソフトウェアを実行する。 When loading software from the external storage 20, the numerical control device 100 of the present disclosure checks the log when the software was executed from the internal storage 10, determines operational restrictions, and executes the software.
　内部ストレージ１０と外部ストレージ２０には、ほぼ同じソフトウェアが格納されている。外部ストレージ２０に格納されたソフトウェアを全て実行すると、エラーの原因となるソフトウェアにデータが書き換えられ、エラーの原因を追究できないおそれがある。
また、エラーの原因となるソフトウェアを実行することにより、再度エラーが発生し、二次被害、三次被害というかたちで数値制御装置１００の故障に繋がることがある。 Almost the same software is stored in the internal storage 10 and the external storage 20. If all the software stored in the external storage 20 is executed, the data will be rewritten to the software that causes the error, and there is a possibility that the cause of the error cannot be investigated.
Moreover, by executing software that causes an error, the error may occur again, leading to a failure of the numerical control device 100 in the form of secondary damage or tertiary damage.
　本開示の数値制御装置１００は、エラーの発生したソフトウェアに動作制限をかけることで、データを上書きすることなく、エラーの原因を追究するためのデータを保存する。また、エラーが発生したソフトウェアによる自動運転や加工を制限し、二次被害、三次被害を防止することができる。 The numerical control device 100 of the present disclosure saves data for investigating the cause of the error without overwriting the data by placing operational restrictions on the software in which the error has occurred. In addition, automatic operation and processing by software in which an error has occurred can be restricted to prevent secondary and tertiary damage.
　なお、図２のフローチャートにおいて、数値制御装置１００における動作制限の内容はこの限りでない。動作制限として、ソフトウェアのロードを一時的に停止し、ソフトウェアを実行するか否かをユーザに問い合わせてもよい。 Note that in the flowchart of FIG. 2, the content of the operation restrictions in the numerical control device 100 is not limited to this. As an operation restriction, loading of the software may be temporarily stopped and the user may be asked whether or not to execute the software.
　また、本開示では、ソフトウェアごとに動作制限をかけたが、タスクやジョブなどソフトウェアよりも小さな単位で動作制限をかけてもよい。 Furthermore, in the present disclosure, operation restrictions are applied to each software, but operation restrictions may be applied in units smaller than software, such as tasks and jobs.
［第２の開示］
　第２の開示の数値制御装置１００は、動作制限登録部１８を備え、動作制限を判定する条件、制限対象となる動作、動作制限の内容を登録することができる。図３は、第２の開示の数値制御装置１００のブロック図である。動作制限登録部１８は、制限対象となる動作と条件と、制限対象となる動作が関連付けて登録されている。 [Second disclosure]
The numerical control device 100 of the second disclosure includes an operation restriction registration unit 18, and can register conditions for determining operation restrictions, operations to be restricted, and contents of the operation restrictions. FIG. 3 is a block diagram of the numerical control device 100 of the second disclosure. In the operation restriction registration unit 18, operations and conditions to be restricted and operations to be restricted are registered in association with each other.
　図４は、動作制限登録部１８の一例である。図４の例では、動作制限の条件として、ソフトウェアを格納するストレージ、エラー発生の有無が登録されている。動作制限の条件は、制限対象となる動作に関連付けて登録されている。
　図４において、内部ストレージ１０に格納されたソフトウェアには、動作制限は存在しない。外部ストレージ２０に格納されたソフトウェアには、動作制限が存在する。図４の例では、「エラーなし」という条件に対して、動作「自動運転」には「動作制限あり」と登録されている。「エラー発生」、エラーの発生場所「不揮発性メモリ」という条件に対して、動作「自動運転」と「パラメータ設定」には「動作制限あり」と登録されている。「エラー発生」、エラーの発生場所「Ｉ／Ｏメモリ」という条件に対して、動作「自動運転」と「データ入出力」には「動作制限あり」と登録されている。 FIG. 4 is an example of the operation restriction registration section 18. In the example of FIG. 4, the storage in which software is stored and the presence or absence of an error are registered as conditions for restricting operation. Conditions for restricting operations are registered in association with operations to be restricted.
In FIG. 4, the software stored in the internal storage 10 has no operational restrictions. The software stored in the external storage 20 has operational limitations. In the example of FIG. 4, for the condition "no error", "operation restrictions" is registered for the operation "automatic operation". For the conditions of "Error Occurrence" and Error Occurrence Location "Nonvolatile Memory", "Operation Restrictions" is registered for the operation "Automatic Operation" and "Parameter Setting". For the conditions of "error occurrence" and location of error occurrence "I/O memory", "operation restrictions" are registered for the operations "automatic operation" and "data input/output".
　動作制限の内容としては、動作の停止、動作のスキップ、ユーザへの問合せなどを行う。動作のスキップでは、現在の動作を停止し、次の動作に移行する。ユーザの問合せでは、ユーザに問合せて動作を停止するか実行するかを判定する。 The contents of the operation restriction include stopping the operation, skipping the operation, and making inquiries to the user. Skipping an operation stops the current operation and moves on to the next operation. In the user inquiry, the user is inquired to determine whether the operation should be stopped or executed.
　ログ解析部１４は、ログを解析して、動作制限の判定に必要な条件を取得する。ログには、ログを出力した日時、ソフトウェア名、エラーの有無、エラーの発生した場所などが記録されている。条件には、エラーの有無、エラーの発生した場所などがある。 The log analysis unit 14 analyzes the log and obtains conditions necessary for determining operation restrictions. The log includes information such as the date and time the log was output, the software name, whether an error occurred, and the location where the error occurred. Conditions include the presence or absence of an error, the location where the error occurred, and so on.
　動作制限部１５は、ストレージの種類と、ログ解析部１４から取得した条件と、動作制限登録部１８に登録した内容とを基に、制限対象となる動作、および動作制限の内容を判定する。 The operation restriction unit 15 determines the operation to be restricted and the content of the operation restriction based on the type of storage, the conditions obtained from the log analysis unit 14, and the contents registered in the operation restriction registration unit 18.
　図５は、ログの一例である。図５を参照して、動作制限の処理を具体的に説明する。ログには、日時「ＸＸ月ＸＸ日　１０：３２」、動作「Ｐｏｗｅｒ　ＯＮ」、・・・、日時「ＸＸ月ＸＸ日　１１：４５」、動作「Ｅｒｒｏｒ：ＤａｔａＡｂｏｒｔ（Ｐａｒａｍｅｔｅｒ　Ｎｏ．１０２２４　Ｌｏｃｋｅｄ）」、日時「ＸＸ月ＸＸ日　１１：４５」、動作「Ｓｙｓｔｅｍ　Ｓｈｕｔｄｏｗｎ」と記載されている。
　ログを解析すると、「ＸＸ月ＸＸ日　１０：３２」に起動し、「ＸＸ月ＸＸ日　１１：４５」にエラーが発生し、エラーの内容は「パラメータ１０２２４のロック」であり、データアボートが発生し、「ＸＸ月ＸＸ日　１１：４５」に数値制御装置１００がシャットダウンしたことが分かる。なお、データアボートとは、正しいアクセス許可なしにデータを読み出し／書込みしようとしたときに発生する例外である。 FIG. 5 is an example of a log. The operation restriction processing will be specifically described with reference to FIG. 5. The log includes the date and time "XX month XX 10:32", the operation "Power ON", ..., the date and time "XX month XX 11:45", the operation "Error: DataAbort (Parameter No. 10224 Locked)", The date and time is "Month/XX 11:45," and the operation is "System Shutdown."
Analyzing the log, it was started at "10:32, day XX, month XX," and an error occurred at "11:45, day XX, month XX."The error content was "Lock parameter 10224," and a data abort occurred. However, it can be seen that the numerical control device 100 was shut down at "11:45 on XX month XX day". Note that a data abort is an exception that occurs when an attempt is made to read/write data without proper access permission.
　図５のログでは、ロック中のパラメータＮｏ．１０２２４にアクセスし、データアボートのエラーが発生している。パラメータは不揮発性メモリに保存されているため、エラーが発生した場所が不揮発性メモリ１１４のパラメータ記憶領域であることが分かる。図５のログでは、パラメータのアクセスでエラーが発生しているため、動作「パラメータの設定」を制限する。 In the log of FIG. 5, the locked parameter No. 10224 and a data abort error occurs. Since the parameters are stored in non-volatile memory, it is known that the location where the error occurred is in the parameter storage area of non-volatile memory 114. In the log of FIG. 5, an error has occurred in parameter access, so the operation "parameter setting" is restricted.
　Ｉ／Ｏメモリには、数値制御装置１００が外部機器とやり取りするデータが保存される。Ｉ／Ｏメモリへのアクセスでエラーが発生した場合、動作「データ入出力」を制限する。 The I/O memory stores data that the numerical control device 100 exchanges with external devices. If an error occurs when accessing the I/O memory, the operation "data input/output" is restricted.
　図６を参照して第２の開示の数値制御装置１００の動作を説明する。
　数値制御装置１００は、通常動作において、内部ストレージ１０からソフトウェアを読み出す（ステップＳ１１）。数値制御装置１００は、内部ストレージ１０から読み出したソフトウェアに従い通常動作を行う。数値制御装置１００は、通常動作において、ログを記録している（ステップＳ１２）。 The operation of the numerical control device 100 of the second disclosure will be described with reference to FIG.
In normal operation, the numerical control device 100 reads software from the internal storage 10 (step S11). The numerical control device 100 performs normal operations according to software read from the internal storage 10. The numerical control device 100 records a log during normal operation (step S12).
　数値制御装置１００に外部ストレージ２０が装着される（ステップＳ１３）。数値制御装置１００は、外部ストレージ２０からソフトウェアをロードする前に、動作制限の判定に必要な条件を取得する（ステップＳ１４）。動作制限の条件には、ソフトウェアが格納されたストレージの種類、外部ストレージ２０からソフトウェアをロードする場合、当該ソフトウェアと同一または類似するソフトウェアを内部ストレージ１０から実行したときのエラーの有無、エラーが発生した場所などがある。ストレージは、数値制御装置１００のＯＳが認識している。エラーの有無、エラーの発生した場所などは、ログに記録されている。 The external storage 20 is attached to the numerical control device 100 (step S13). Before loading the software from the external storage 20, the numerical control device 100 acquires conditions necessary for determining operation restrictions (step S14). Conditions for operating restrictions include the type of storage where the software is stored, when loading software from the external storage 20, whether there is an error when software that is the same or similar to the software is executed from the internal storage 10, and whether an error occurs. There are places where I did it. The storage is recognized by the OS of the numerical control device 100. The presence or absence of an error and the location where the error occurred are recorded in the log.
　数値制御装置１００は、外部ストレージ２０からソフトウェアをロードする（ステップＳ１５）。外部ストレージ２０の装着は、数値制御装置１００のエラー発生時のバックアップ、数値制御装置１００のメンテナンスなどのタイミングで行う。また、ステップＳ１３の外部ストレージの装着する前に、数値制御装置１００の電源をＯＦＦし、外部ストレージを装着したのち、数値制御装置１００を起動してもよい。 The numerical control device 100 loads software from the external storage 20 (step S15). The external storage 20 is installed at the timing of backup when an error occurs in the numerical control device 100, maintenance of the numerical control device 100, etc. Furthermore, before installing the external storage in step S13, the power of the numerical control device 100 may be turned off, and after installing the external storage, the numerical control device 100 may be started.
　数値制御装置１００は、動作制限の判定に必要な条件と、動作制限登録部１８に登録された内容とを基に、制限対象となる動作と、動作制限の内容とを判定する（ステップＳ１６）。
　制限対象となる動作が存在する場合（ステップＳ１７；Ｙｅｓ）、数値制御装置１００は、動作制限の内容に従い動作を制限する（ステップＳ１８）。制限対象となる動作が存在しない場合（ステップＳ１７；Ｎｏ）は、制限なく実行する（ステップＳ１９）。 The numerical control device 100 determines the operation to be restricted and the content of the operation restriction based on the conditions necessary for determining the operation restriction and the contents registered in the operation restriction registration unit 18 (step S16). .
If there is an operation to be restricted (step S17; Yes), the numerical control device 100 restricts the operation according to the content of the operation restriction (step S18). If there is no operation to be restricted (step S17; No), the operation is executed without restriction (step S19).
　動作制限では、書き換え禁止状態でソフトウェアにロックをかける。動作制限の手段としては、動作フラグや動作の開始信号などがある。動作フラグは、動作制限の要／不要を示す。数値制御装置１００は、動作フラグに従い、ソフトウェアの動作を制限する。また、数値制御装置１００が、ソフトウェアの開始信号を監視し、開始信号が全てＯＦＦの場合には、ソフトウェアの実行を制限する。 Operation restriction locks the software in a state where rewriting is prohibited. As means for limiting the operation, there are an operation flag, an operation start signal, and the like. The operation flag indicates whether or not operation restriction is necessary. The numerical control device 100 limits the operation of the software according to the operation flag. Further, the numerical control device 100 monitors the start signals of the software, and limits the execution of the software when all the start signals are OFF.
　以上説明したように、第２の開示の数値制御装置１００では、動作制限の内容を登録する動作制限登録部１８を備える。動作制限の内容は、条件と紐づけられている。数値制御装置１００は、動作制限の条件を取得し、取得した条件を基に、制限対象となるソフトウェアの動作および動作制限の内容を判定する。 As described above, the numerical control device 100 of the second disclosure includes the operation restriction registration unit 18 that registers the contents of the operation restriction. The contents of the operation restriction are linked to the conditions. The numerical control device 100 acquires the conditions of the operation restriction, and determines the operation of the software to be restricted and the content of the operation restriction based on the acquired condition.
　第２の開示の数値制御装置１００は、ログを解析してエラーの発生場所を判定し、エラーの発生場所が記憶装置（不揮発性メモリ、Ｉ／Ｏメモリなど）であれば、その記憶装置を書き換える動作を制限する。例えば、不揮発性メモリ１１４のパラメータ記憶領域でエラーが発生した場合には、動作「パラメータ設定」を制限する。また、Ｉ／Ｏメモリは、外部機器や周辺機器とのデータの入出力で書き換えられるおそれがあるため、動作「データ入出力」を制限する。このように、ソフトウェアを動作させながら、エラーが発生したソフトウェアによるデータの書き換えを制限することができる。 The numerical control device 100 of the second disclosure analyzes the log to determine the location where the error occurs, and if the location where the error occurs is a storage device (nonvolatile memory, I/O memory, etc.), the storage device is Restrict rewriting operations. For example, if an error occurs in the parameter storage area of the nonvolatile memory 114, the "parameter setting" operation is restricted. Furthermore, since there is a risk that the I/O memory may be rewritten due to data input/output with external devices or peripheral devices, the operation "data input/output" is restricted. In this way, it is possible to restrict data rewriting by software in which an error has occurred while operating the software.
　図７は、数値制御装置１００のハードウェア構成図である。数値制御装置１００が備えるＣＰＵ１１１は、数値制御装置１００を全体的に制御するプロセッサである。ＣＰＵ１１１は、バスを介してＲＯＭ１１２に加工されたシステム・プログラムを読み出し、該システム・プログラムに従って数値制御装置１００の全体を制御する。ＲＡＭ１１３には、一時的な計算データや表示データ、入力部７１を介してユーザが入力した各種データ等が一時的に格納される。 FIG. 7 is a hardware configuration diagram of the numerical control device 100. The CPU 111 included in the numerical control device 100 is a processor that controls the numerical control device 100 as a whole. The CPU 111 reads a system program stored in the ROM 112 via the bus, and controls the entire numerical control device 100 in accordance with the system program. The RAM 113 temporarily stores temporary calculation data, display data, various data input by the user via the input unit 71, and the like.
　数値制御装置１００は、インターフェース１１５を介して情報ネットワークに接続され、内蔵ＰＬＣ１２０を介して産業ネットワークに接続されている。 The numerical control device 100 is connected to an information network via an interface 115 and to an industrial network via a built-in PLC 120.
　表示部７０は、数値制御装置１００に付属のモニタなどである。表示部７０は、数値制御装置１００の操作画面や設定画面などを表示する。 The display unit 70 is a monitor attached to the numerical control device 100 or the like. The display unit 70 displays an operation screen, a setting screen, etc. of the numerical control device 100.
