Description

ロギング設定装置、ロギング設定方法および記録媒体Logging setting device, logging setting method, and recording medium
　本発明は、プログラマブルコントローラ（ＰＬＣ）のロギング設定を行うロギング設定装置、ロギング設定方法および当該ロギング設定方法をコンピュータに実行させるプログラムを記録した記録媒体に関する。 The present invention relates to a logging setting device that performs logging setting of a programmable controller (PLC), a logging setting method, and a recording medium that records a program that causes a computer to execute the logging setting method.
　従来、ＰＬＣには、デバイス値をロギングする機能を備えたものがある。どのデバイスをロギング対象とするかは、プログラミング装置（ロギング設定装置）を用いてＰＬＣに設定される。ユーザは、取り扱い説明書（以下、単にマニュアル）の記載例を参考にしてユーザプログラムを作成したとき、マニュアルに記載されている動作例と比較するために、参考にした部分の動作例として記載されているデバイスと同一のデバイスの値をロギングしたい場合がある。 Conventionally, some PLCs have a function for logging device values. Which device is targeted for logging is set in the PLC using a programming device (logging setting device). When a user creates a user program with reference to an example in an instruction manual (hereinafter simply referred to as a manual), it is described as an operation example of the referenced part for comparison with the operation example described in the manual. You may want to log the same device value as the current device.
　一方、ＰＬＣには、ＰＬＣ全体の動作を統括的に制御するＣＰＵユニットと、目的に合わせて適宜選択されるサブユニットとがベースユニットに装着されて構成されるタイプのものがある。このようなタイプのＰＬＣの場合、デバイスの割り付けアドレスは、サブユニットの装着位置に応じて変化する。したがって、ユーザは、ロギング設定の際、マニュアルに記載されているデバイスに対応するデバイスを求める作業を行う必要が生じる。特に、マニュアルに１つのプログラム例に対して複数の関連するデバイスの動作例が記載されている場合、当該複数のデバイスに夫々対応するデバイスをいちいち求める必要があり、ユーザにとってロギング設定の作業が非常に煩雑であった。 On the other hand, there is a type of PLC in which a CPU unit that comprehensively controls the operation of the entire PLC and a subunit that is appropriately selected according to the purpose are mounted on the base unit. In the case of such a type of PLC, the device allocation address changes according to the mounting position of the subunit. Therefore, the user needs to perform an operation for obtaining a device corresponding to the device described in the manual when logging is set. In particular, when an example of operation of a plurality of related devices is described for one program example in the manual, it is necessary to find a device corresponding to each of the plurality of devices one by one. It was complicated.
　ユーザによるデバイスの設定を支援する技術としては、例えば特許文献１には、ユーザがモニタしたいソレノイドやコイルなどのデバイスを指定すると、ユーザプログラムから指定したデバイスに関係するデバイスを検索し、全ての関連デバイスを含めて状態をモニタする装置にかかる技術が開示されている。 As a technique for assisting the user in setting a device, for example, in Patent Document 1, when a device such as a solenoid or a coil that the user wants to monitor is specified, a device related to the specified device is searched from the user program, and all related A technique related to an apparatus that monitors a state including a device is disclosed.

　しかしながら、上記従来の技術によれば、ユーザプログラムを検査することによって関連各要素を抽出するようになっているので、例えばインテリジェントユニットのようにユーザプログラムとは異なるプログラムに基づいて動作するユニットを使用する場合、当該ユニットが中間データの格納領域として使用するデバイスを抽出することができないという問題があった。 However, according to the above-described conventional technology, since each related element is extracted by examining the user program, a unit that operates based on a program different from the user program, such as an intelligent unit, is used. In such a case, there is a problem that a device used by the unit as an intermediate data storage area cannot be extracted.
　本発明は、上記に鑑みてなされたものであって、可及的に簡単にロギング設定を行うことができるロギング設定装置、ロギング設定方法および当該ロギング設定方法をコンピュータに実行させるプログラムを記録した記録媒体を得ることを目的とする。 The present invention has been made in view of the above, and is a logging setting device capable of performing logging setting as easily as possible, a logging setting method, and a recording in which a program for causing a computer to execute the logging setting method is recorded The purpose is to obtain a medium.
　上述した課題を解決し、目的を達成するために、本発明は、デバイスを指定する入力を受け付けて、ロギング設定対象のプログラマブルコントローラ（ＰＬＣ）を構成するユニットの形名と当該ユニットが使用するデバイスアドレス空間の先頭アドレスとの対応を記述した予め作成されたユニット情報リストから、前記指定されたデバイスを使用するユニットの形名および当該ユニットの先頭アドレスを取得するユニット情報取得部と、ユニット毎に制御動作の典型例の名称と当該制御動作にかかる関連デバイス群との対応付けを、関連デバイス群を構成するデバイス毎にデバイスアドレスと先頭アドレスとの関係を示す先頭アドレス依存性とともに記憶しているロギング設定項目群データベースと、前記ユニット情報取得部が取得したユニットの形名を検索キーとして前記ロギング設定項目群データベースを検索して、当該ユニットにかかる制御動作の典型例の名称の一覧を抽出する関連項目群抽出部と、ユーザから前記抽出した制御動作の名称の一覧のうちの一つを選択する入力を受け付けて、前記選択された制御動作に対応づけられている関連デバイス群を構成する夫々のデバイスのアドレスを前記ロギング設定項目群データベースが記憶している先頭アドレス依存性と前記取得した先頭アドレスとに基づいて変更するデバイス変更部と、前記変更された関連デバイス群を構成する夫々のデバイスをロギング対象に設定するロギング設定出力部と、を備えることを特徴とする。 In order to solve the above-described problems and achieve the object, the present invention accepts an input specifying a device, and forms a model name of a unit constituting a programmable controller (PLC) to be set for logging and a device used by the unit. For each unit, a unit information acquisition unit that acquires the model name of the unit that uses the specified device and the start address of the unit from the unit information list that describes the correspondence with the start address of the address space. The correspondence between the name of the typical example of the control operation and the related device group related to the control operation is stored together with the start address dependency indicating the relationship between the device address and the start address for each device constituting the related device group. Logging setting item group database and the user acquired by the unit information acquisition unit A related item group extraction unit that searches the logging setting item group database using a model name as a search key and extracts a list of typical examples of control operations related to the unit, and the control operation extracted from the user The logging setting item database stores the address of each device constituting the related device group associated with the selected control operation in response to an input for selecting one of the list of names.

　以下に、本発明にかかるロギング設定装置、ロギング設定方法および記録媒体の実施の形態を図面に基づいて詳細に説明する。なお、この実施の形態によりこの発明が限定されるものではない。 Hereinafter, embodiments of a logging setting device, a logging setting method, and a recording medium according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.
実施の形態．
　図１は、ロギング設定の対象となるプログラマブルコントローラ（ＰＬＣ）の構成例を説明する図である。図示するように、ＰＬＣ１は、ＣＰＵユニット２と、サブユニットのうちの１つとしてのインテリジェントユニット３とがバスユニット４に接続されて構成されている。 Embodiment.
FIG. 1 is a diagram illustrating a configuration example of a programmable controller (PLC) that is a target of logging setting. As shown in the figure, the PLC 1 is configured by connecting a CPU unit 2 and an intelligent unit 3 as one of the subunits to a bus unit 4.
　ＣＰＵユニット２は、ユーザプログラム２５に基づいてＰＬＣ１全体を統括的に制御するユニットである。インテリジェントユニット３は、ＣＰＵユニット２とは異なる別個のＣＰＵ３１を備え、独自のプログラム（ユニットプログラム３３）に基づいてＣＰＵユニット２のスレーブとして動作するユニットである。インテリジェントユニット３の例としては、例えば、ユーザプログラム２５からの指令に基づいて、駆動軸などに取り付けられたモータを駆動するサーボアンプに対する駆動指令を算出する位置決めユニットなどがある。なお、バスユニット４には、目的に応じて、ＣＰＵユニット２をさらに増設してＣＰＵユニット２を二重化したり、インテリジェントユニット３の他にさらに別のサブユニットを装着することができるようになっている。 The CPU unit 2 is a unit that comprehensively controls the entire PLC 1 based on the user program 25. The intelligent unit 3 includes a separate CPU 31 different from the CPU unit 2 and operates as a slave of the CPU unit 2 based on a unique program (unit program 33). Examples of the intelligent unit 3 include a positioning unit that calculates a drive command for a servo amplifier that drives a motor attached to a drive shaft or the like based on a command from the user program 25. Depending on the purpose, the CPU unit 2 can be further added to the bus unit 4 so that the CPU unit 2 can be duplicated, or another sub unit other than the intelligent unit 3 can be mounted. Yes.
　ＣＰＵユニット２は、ＣＰＵ２１、記憶装置２２、および通信インタフェース２３を備えている。これらの各要素は内部バスで互いに接続されている。 The CPU unit 2 includes a CPU 21, a storage device 22, and a communication interface 23. Each of these elements is connected to each other by an internal bus.
　記憶装置２２は、ＲＯＭ（Ｒｅａｄ　Ｏｎｌｙ　Ｍｅｍｏｒｙ）やＲＡＭ（Ｒａｎｄｏｍ　Ａｃｃｅｓｓ　Ｍｅｍｏｒｙ）などにより構成されており、ユニット情報リスト２４、ユーザプログラム２５、およびロギング設定データ２６を記憶している。また、記憶装置２２には、デバイスアドレスが割り当てられ、デバイス値が格納されるデバイスメモリ領域２７と、ログデータが格納されるログデータ格納領域２８とが確保されている。ユニット情報リスト２４は、バスユニット４に装着されているサブユニットの形名と当該サブユニットが使用するデバイスの割り当て先のオフセットアドレスである先頭ＸＹとが記述されたユニット情報のリストである。先頭ＸＹは、当該サブユニットの装着位置に依存して変化する。ロギング設定データ２６は、ロギングの対象となるデバイスを記述した設定情報である。ユニット情報リスト２４およびロギング設定データ２６は、ユーザプログラム２５とともにユーザによりプログラミング装置を用いて設定される。なお、ＣＰＵユニット２が装着されているユニットから自動的に装着位置や形名を取得して、取得した情報に基づいてユニット情報リスト２４を自動で作成するように構成されている場合もある。また、ユーザがプログラミング装置を用いてユニット情報リスト２４を編集することによってサブユニット毎の先頭ＸＹがユーザの任意に設定される場合もある。 The storage device 22 includes a ROM (Read Only Memory), a RAM (Random Access Memory), and the like, and stores a unit information list 24, a user program 25, and logging setting data 26. In addition, a device address is assigned to the storage device 22, and a device memory area 27 in which device values are stored and a log data storage area 28 in which log data is stored are secured. The unit information list 24 is a list of unit information in which the model name of the sub unit mounted on the bus unit 4 and the head XY that is the offset address of the device to which the sub unit is assigned are described. The leading XY changes depending on the mounting position of the subunit. The logging setting data 26 is setting information describing a device to be logged. The unit information list 24 and the logging setting data 26 are set by the user together with the user program 25 using a programming device. Note that there may be a case where the mounting position and model name are automatically acquired from the unit in which the CPU unit 2 is mounted, and the unit information list 24 is automatically created based on the acquired information. In some cases, the user may arbitrarily set the top XY for each subunit by editing the unit information list 24 using a programming device.
　ＣＰＵ２１は、ユーザプログラム２５を実行することによって同一のＰＬＣ１が備えるサブユニットの制御を実行する。具体的には、ＣＰＵ２１は、サブユニットから当該サブユニットに対してデバイスメモリ領域２７に割り当てられている入力デバイスに書き込まれた入力値を取得して、取得した入力値を用いて当該サブユニットに対する出力値を算出する。また、ＣＰＵ２１は、当該算出した出力値を当該サブユニットに対してデバイスメモリ領域２７に割り当てられている所定の出力デバイスに格納する。また、ＣＰＵ２１は、サブユニットとの間でデバイスを介して入出力するだけでなく、デバイスメモリ領域２７における入力デバイスまたは出力デバイスと異なるデバイスに中間データを格納することもある。なお、デバイスアドレスは、後述のインテリジェントユニット３が備えるバッファメモリ領域３４にも割り当てられており、ＣＰＵ２１は、バッファメモリ領域３４に割り当てられているデバイスアドレスを指定することにより当該バッファメモリ３４に対して直接アクセスを行うこともできる。 CPU21 performs control of the subunit with which the same PLC1 is provided by running the user program 25. FIG. Specifically, the CPU 21 acquires an input value written in an input device assigned to the device memory area 27 from the subunit to the subunit, and uses the acquired input value for the subunit. Calculate the output value. Further, the CPU 21 stores the calculated output value in a predetermined output device assigned to the device memory area 27 for the subunit. The CPU 21 not only inputs / outputs data to / from the subunit via a device, but also stores intermediate data in a device different from the input device or the output device in the device memory area 27. The device address is also assigned to a buffer memory area 34 provided in the intelligent unit 3 to be described later, and the CPU 21 designates the device address assigned to the buffer memory area 34 so as to Direct access is also possible.
　さらに、ＣＰＵ２１は、ロギング設定データ２６に設定されているデバイスアドレスの値を逐次取得して、取得したデバイス値をログデータとしてログデータ格納領域２８に蓄積記憶させる。ユーザは、ログデータ格納領域２８に逐次入力されるログデータをプログラマブル表示器から略リアルタイムで取得してＰＬＣ１の制御動作をモニタリングしたり、ログデータ格納領域２８に蓄積記憶されているログデータをプログラミング装置やプログラマブル表示器から所定のタイミングで一括取得して、事後の解析に供したりすることができる。 Further, the CPU 21 sequentially acquires the device address value set in the logging setting data 26 and accumulates and stores the acquired device value in the log data storage area 28 as log data. The user acquires the log data sequentially input to the log data storage area 28 from the programmable display in substantially real time to monitor the control operation of the PLC 1 or program the log data stored and stored in the log data storage area 28 It can be acquired from the device or programmable display at a predetermined timing and used for subsequent analysis.
　通信Ｉ／Ｆ２３は、外部機器を接続するための通信インタフェースであって、ユーザは当該通信Ｉ／Ｆ２３に本実施の形態のプログラミング装置を接続してユーザプログラム２５やロギング設定データ２６の設定を行うことができるようになっている。 The communication I / F 23 is a communication interface for connecting an external device, and the user connects the programming device of the present embodiment to the communication I / F 23 to set the user program 25 and the logging setting data 26. Be able to.
　インテリジェントユニット３は、ＣＰＵ３１と記憶装置３２とを備えている。ＣＰＵ３１および記憶装置３２はバスで互いに接続されている。 The intelligent unit 3 includes a CPU 31 and a storage device 32. The CPU 31 and the storage device 32 are connected to each other by a bus.
　記憶装置３２は、ＲＯＭやＲＡＭなどにより構成されており、ユニットプログラム３３を記憶している。また、記憶装置３２にはバッファメモリ領域３４が確保されている。ユニットプログラム３３は、ユーザプログラム２５からの指令により動作するプログラムであって、ＣＰＵ３１により実行されることによってインテリジェントユニット３に求められる機能を実現するものである。例えばインテリジェントユニット３が位置決めユニットであった場合、ユーザプログラム２５から位置指令が入力されると、ＣＰＵ３１は、ユニットプログラム３３に基づいて、入力された位置指令よりも粒度が細かい駆動指令を算出する。ＣＰＵ３１は、ユニットプログラム３３を実行する際に生成される中間データをバッファメモリ領域３４における所定の領域に格納する。ＣＰＵユニット２とインテリジェントユニット３との間の入出力は、デバイスメモリ領域２７またはバッファメモリ領域３４に割り当てられているデバイスを用いて実行される。また、ＣＰＵユニット２はバッファメモリ領域３４に割り当てられているデバイスを用いてバッファメモリ領域３４に格納されている前述の中間データを取得することができる。なお、以降、インテリジェントユニット３は複数軸の駆動制御が可能な位置決めユニットであり、当該複数軸は１から順番に昇順に軸番号が付されて互いに識別できるようになっているものとする。 The storage device 32 is configured by a ROM, a RAM, or the like, and stores a unit program 33. In addition, a buffer memory area 34 is secured in the storage device 32. The unit program 33 is a program that operates in response to a command from the user program 25, and implements a function required for the intelligent unit 3 when executed by the CPU 31. For example, when the intelligent unit 3 is a positioning unit, when a position command is input from the user program 25, the CPU 31 calculates a drive command with a finer granularity than the input position command based on the unit program 33. The CPU 31 stores intermediate data generated when the unit program 33 is executed in a predetermined area in the buffer memory area 34. Input / output between the CPU unit 2 and the intelligent unit 3 is executed using a device allocated to the device memory area 27 or the buffer memory area 34. Further, the CPU unit 2 can acquire the above-described intermediate data stored in the buffer memory area 34 by using a device assigned to the buffer memory area 34. Hereinafter, it is assumed that the intelligent unit 3 is a positioning unit capable of driving control of a plurality of axes, and the plurality of axes are assigned an axis number in ascending order from 1 so that they can be distinguished from each other.
　図２は、マニュアルに記載されているインテリジェントユニット（位置決めユニット）３の制御にかかるユーザプログラムの一例を説明する図である。当該マニュアルは、インテリジェントユニット３の割り当てアドレスの先頭ＸＹがゼロ値であり、軸１の駆動制御を行うものとして作成されている。このマニュアルにおいては、位置決め始動信号Ｙ１０、始動完了信号Ｘ１０および位置決め始動指令パルスＭ１０４がユーザプログラム中で使用されている。 FIG. 2 is a diagram for explaining an example of a user program related to the control of the intelligent unit (positioning unit) 3 described in the manual. The manual is created so that the head XY of the allocation address of the intelligent unit 3 has a zero value and the drive control of the axis 1 is performed. In this manual, a positioning start signal Y10, a start completion signal X10, and a positioning start command pulse M104 are used in the user program.
　図３は、図２に示すプログラム例にかかるインテリジェントユニット３の動作例を示すタイミングチャートである。通常、マニュアルには、ユーザが正しくユーザプログラムを作成できているか否かをチェックできるように、プログラム例の中で用いられているデバイスだけでなく、当該プログラム例を実行したときの中間データが格納されるデバイスなど、当該プログラム例に密接に関連するデバイスの動作例が記載される。図３のタイミングチャートによれば、図２のプログラムによって、ユーザプログラム中で使用されているＹ１０、Ｘ１０、Ｍ１０４の他に、シーケンサレディ信号Ｙ０、ユニット準備完了信号Ｘ０、ＢＵＳＹ信号ＸＣ、位置決め完了信号Ｘ１４、エラー検出信号Ｘ８および送り速度Ｕ０￥Ｇ８０４が夫々密接に関連する動作を行うことが示されている。 FIG. 3 is a timing chart showing an operation example of the intelligent unit 3 according to the program example shown in FIG. Normally, the manual stores not only the devices used in the program example but also intermediate data when the program example is executed so that the user can check whether the user program has been created correctly. An example of the operation of a device closely related to the example program is described. According to the timing chart of FIG. 3, according to the program of FIG. 2, in addition to Y10, X10, and M104 used in the user program, the sequencer ready signal Y0, the unit preparation completion signal X0, the BUSY signal XC, and the positioning completion signal X14, error detection signal X8 and feed rate U0 \ G804 are shown to perform closely related operations.
　具体的に説明すると、ＣＰＵユニット２がシーケンサレディ信号Ｙ０をオンすると、インテリジェントユニット３はユニット準備完了信号Ｘ０をオンする。その後、ＣＰＵユニット２が位置決め始動信号Ｙ１０をオンすると、インテリジェントユニット３は軸１の駆動制御を開始して始動完了信号Ｘ１０およびＢＵＳＹ信号ＸＣをオンする。そして、インテリジェントユニット３は、位置指令により指令された位置に軸１が到達する毎に位置決め完了信号Ｘ１４をパルス的にオンする。インテリジェントユニット３は、ユニットプログラム３３により定められた一連の動作を完了すると、ＢＵＳＹ信号をオフし、ＢＵＳＹ信号のオフを確認してＣＰＵユニット２が位置決め始動信号をオフする。インテリジェントユニット３は位置決め始動信号のオフを確認してから始動完了信号Ｘ１０をオフする。 More specifically, when the CPU unit 2 turns on the sequencer ready signal Y0, the intelligent unit 3 turns on the unit preparation completion signal X0. Thereafter, when the CPU unit 2 turns on the positioning start signal Y10, the intelligent unit 3 starts driving control of the shaft 1 and turns on the start completion signal X10 and the BUSY signal XC. The intelligent unit 3 turns on the positioning completion signal X14 in a pulse manner every time the shaft 1 reaches the position commanded by the position command. When the intelligent unit 3 completes a series of operations determined by the unit program 33, it turns off the BUSY signal, confirms that the BUSY signal is turned off, and the CPU unit 2 turns off the positioning start signal. The intelligent unit 3 turns off the start completion signal X10 after confirming that the positioning start signal is turned off.
　なお、インテリジェントユニット３は、動作中、現在の送り速度を中間データとしてデバイスＵ０￥Ｇ８０４が割り当てられた位置に逐次出力する。デバイスＵ０￥Ｇ８０４は、バッファメモリ領域３４に割り当てられた中間データを格納するためのデバイスであって、通常、ユーザプログラム２５中には使用されないものである。また、インテリジェントユニット３は、動作中にエラーを検出した場合、エラー検出信号Ｘ８をオンする。 In addition, during operation, the intelligent unit 3 sequentially outputs the current feed speed as intermediate data to a position to which the device U0 \ G804 is assigned. The device U0 \ G804 is a device for storing intermediate data allocated to the buffer memory area 34, and is normally not used in the user program 25. The intelligent unit 3 turns on the error detection signal X8 when an error is detected during operation.
　このように、図２のプログラム例に密接に関連するデバイスとしてＹ１０、Ｙ０、Ｘ０、Ｘ１０、ＸＣ、Ｘ１４、Ｘ８、Ｕ０￥Ｇ８０４が取り上げられ、各デバイスについて動作例が記載されている。図２のプログラム例を用いて作成したユーザプログラムにおける前記プログラム例部分の動作を確認するためには、ユーザは、Ｙ１０、Ｙ０、Ｘ０、Ｘ１０、ＸＣ、Ｘ１４、Ｘ８、Ｕ０￥Ｇ８０４をロギング対象に設定するとよいこととなる。以降、Ｘ１０、Ｙ０、Ｘ０、Ｘ１０、ＸＣ、Ｘ１４、Ｘ８、Ｕ０￥Ｇ８０４のように、マニュアルにおいて１つのプログラムの設定例に対して動作例が記載されている複数のデバイスを関連デバイス群、当該関連デバイス群を構成する個々のデバイスを関連デバイスということとする。 Thus, Y10, Y0, X0, X10, XC, X14, X8, U0 \ G804 are taken up as devices closely related to the program example of FIG. 2, and an operation example is described for each device. In order to confirm the operation of the program example portion in the user program created using the program example of FIG. 2, the user sets Y10, Y0, X0, X10, XC, X14, X8, U0 \ G804 as the logging target. It is good to set. Thereafter, a plurality of devices whose operation examples are described in a manual setting example, such as X10, Y0, X0, X10, XC, X14, X8, U0 \ G804, are related device groups, Individual devices constituting the related device group are referred to as related devices.
　ここで、インテリジェントユニット３の装着位置によって先頭ＸＹが０ではない場合や、軸１以外を制御対象とする場合、関連デバイスのアドレスを変更して使用する必要が生じる。図４は、先頭ＸＹが２０であって、軸３を駆動対象とする場合のプログラム例である。 Here, when the leading XY is not 0 depending on the mounting position of the intelligent unit 3 or when the control target is other than the axis 1, it is necessary to change the address of the related device. FIG. 4 shows a program example in the case where the head XY is 20 and the axis 3 is the driving target.
　図４に示すように、マニュアルではＹ１０が使用されていた位置決め始動信号がＹ３２に変更されている。これは、Ｙ３２の「３２」は、マニュアルでのアドレスＹ１０の「１０」に先頭ＸＹの値「２０」と軸番号から１減算して得られる値「２」とを加算したオフセット「２２」が加えられた値となっている。Ｙ３２の場合と同様に、マニュアルでＸ１０が使用されていた始動完了信号が、オフセット「２２」が加算されてＸ３２に変更されている。このように変更されている場合、ロギング対象の関連デバイスを構成する各デバイスのアドレスも変更する必要がある。また、デバイスアドレスの数字部分が先頭ＸＹに依存するか否かおよび軸番号に依存するか否かはデバイス毎に異なるため、関連デバイス毎にアドレスを変更してロギング対象に設定する作業はユーザにとって煩雑な作業である。本発明の実施の形態のロギング設定装置は、ユーザがロギング対象のデバイスアドレスを簡単に設定することができるように、関連デバイス群毎に予め関連デバイスが登録され、各関連デバイスのアドレスを自動で変更できるようにしたことが主たる特徴となっている。 As shown in FIG. 4, in the manual, the positioning start signal for which Y10 was used has been changed to Y32. This is because “32” of Y32 has an offset “22” obtained by adding the value “2” obtained by subtracting 1 from the head XY value “20” and the axis number to “10” of the manual address Y10. It is an added value. As in the case of Y32, the start completion signal in which X10 was manually used is changed to X32 by adding the offset “22”. When the change is made in this way, it is necessary to change the address of each device constituting the related device to be logged. Also, whether the numeric part of the device address depends on the head XY and whether it depends on the axis number differs depending on the device, so it is difficult for the user to change the address for each related device and set it as a logging target. It is a complicated task. In the logging setting device according to the embodiment of the present invention, the related device is registered in advance for each related device group so that the user can easily set the device address to be logged, and the address of each related device is automatically set. The main feature is that it can be changed.
　図５は、本実施の形態のロギング設定装置としてのプログラミング装置の構成例を説明する図である。本実施の形態では、ロギング設定装置はプログラミング装置の一機能として実装されるものとして説明するが、ロギング設定装置はプログラミング装置とは別の装置として構成するようにしてもよい。図示するように、プログラミング装置５は、ＣＰＵ５１、ＲＡＭ５２、ＲＯＭ５３、通信Ｉ／Ｆ５４、外部記憶装置５５、ＣＤ－ＲＯＭドライブ５６、入力装置５７、および出力装置５８を備えた通常のコンピュータの構成を備えている。ＣＰＵ５１、ＲＡＭ５２、ＲＯＭ５３、通信Ｉ／Ｆ５４、外部記憶装置５５、ＣＤ－ＲＯＭドライブ５６、入力装置５７、および出力装置５８は夫々バスを介して接続されている。 FIG. 5 is a diagram illustrating a configuration example of a programming device as a logging setting device according to the present embodiment. In this embodiment, the logging setting device is described as being implemented as a function of the programming device. However, the logging setting device may be configured as a device different from the programming device. As shown in the figure, the programming device 5 has a configuration of a normal computer including a CPU 51, a RAM 52, a ROM 53, a communication I / F 54, an external storage device 55, a CD-ROM drive 56, an input device 57, and an output device 58. ing.

　ＣＰＵ５１は、ロギング設定を実行するためのコンピュータプログラムであるロギング設定プログラム６２を実行する。出力装置５８は、液晶モニタなどの表示装置であり、ＣＰＵ５１からの指示に基づいて、操作画面などのユーザに対する出力情報を表示する。入力装置５７は、マウスやキーボードを備えて構成され、ユーザからのプログラミング装置５に対する操作が入力される。入力装置５７へ入力された操作情報は、ＣＰＵ５１へ送られる。通信Ｉ／Ｆ５４は、ＣＰＵユニット２との間で通信を行うための接続インタフェースである。当該通信Ｉ／Ｆ５４を介してＣＰＵユニット２にユーザプログラム２５、ロギング設定データ２６が設定される。ＲＯＭ５３は、プログラミング装置５が起動するためのブート情報を記憶しており、ブート時にはＣＰＵ５１が当該ブート情報に基づいて例えばハードディスクドライブにより構成される外部記憶装置５５に格納されているシステムプログラム（図示せず）を起動してプログラミング装置５が起動する。 The CPU 51 executes a logging setting program 62 that is a computer program for executing logging settings.

The CPU 51 executes a logging setting program 62 loaded in the RAM 52. The external storage device 55 stores a unit information list 60 and a user program 61 in advance. The user program 61 is created using, for example, the programming device 5, and the unit information list 60 is obtained from the PLC 1, for example. The CPU 51 executes various steps described later by executing the logging setting program loaded in the RAM 52, and outputs logging setting data.

　図６は、ＲＡＭ５２にロードされたロギング設定プログラム６２が実行されることにより実現するプログラミング装置５の機能構成を説明する図である。図示するように、プログラミング装置５は、ユニット情報取得部７０、関連項目群抽出部７１、ロギング設定項目群データベース（ＤＢ）７２、関連項目群表示／選択部７３、オフセット反映部７４、およびロギング設定出力部７５を備える。これらの機能構成要素はそれぞれ例えばＲＡＭ５２内に生成される。 FIG. 6 is a diagram illustrating a functional configuration of the programming device 5 realized by executing the logging setting program 62 loaded in the RAM 52. As illustrated, the programming device 5 includes a unit information acquisition unit 70, a related item group extraction unit 71, a logging setting item group database (DB) 72, a related item group display / selection unit 73, an offset reflection unit 74, and a logging setting. An output unit 75 is provided. Each of these functional components is generated in the RAM 52, for example.
　ユニット情報取得部７０は、ユーザからの入力装置５７を介した入力に基づいてユニット情報リスト６０を検索して、ロギング対象のユニットにかかるユニット情報（ユニット形名および先頭ＸＹ）を取得する。なお、ここでは外部記憶装置５５に予め格納されているユニット情報リスト６０からユニット情報を取得するとしているが、当該プログラミング装置５がＰＬＣ１に接続されている場合、ＣＰＵユニット２に設定されているユニット情報リスト２４から取得するようにしてもよい。 The unit information acquisition unit 70 searches the unit information list 60 based on input from the user via the input device 57, and acquires unit information (unit model name and head XY) related to the logging target unit. Here, the unit information is acquired from the unit information list 60 stored in advance in the external storage device 55. However, when the programming device 5 is connected to the PLC 1, the unit set in the CPU unit 2 is used. You may make it acquire from the information list 24. FIG.
　ロギング設定項目群ＤＢ７２は、ロギング設定項目と当該ロギング設定項目に関連する関連デバイス一覧との対応付けをユニット毎に管理するデータベースである。図７は、ロギング設定項目群ＤＢ７２のデータ構造例を説明する図である。 The logging setting item group DB 72 is a database that manages the association between the logging setting item and the related device list related to the logging setting item for each unit. FIG. 7 is a diagram for explaining an example of the data structure of the logging setting item group DB 72.
　図７の上部に示すように、ロギング設定項目群ＤＢ７２は、形名、ロギング設定項目名、および関連デバイスを記述するフィールドを有するテーブル形式のデータ構造を備えている。ロギング設定項目名は関連デバイス群を識別するための名称である。ここでは、関連デバイス群はマニュアルに記載されているプログラム例毎に規定されているとしているので、ロギング設定項目名には、マニュアルに記載されているプログラム例を互いに識別しやすい名称を用いるとよい。例えば図２のプログラム例にかかる関連デバイス群は、ロギング設定項目名「ブロック始動制御」が付されている。ユニット形名１つあたりに登録されるロギング設定項目名の数は特に限定されない。また、複数のロギング設定項目の関連デバイスに同一のデバイスアドレスが登録される場合もある。 As shown in the upper part of FIG. 7, the logging setting item group DB 72 has a table-type data structure having fields that describe a model name, a logging setting item name, and a related device. The logging setting item name is a name for identifying a related device group. Here, since the related device group is defined for each program example described in the manual, it is recommended to use a name that makes it easy to identify the program examples described in the manual as the logging setting item name. . For example, the related device group according to the program example of FIG. 2 is given the logging setting item name “block start control”. The number of logging setting item names registered per unit type name is not particularly limited. In addition, the same device address may be registered in related devices of a plurality of logging setting items.
　ロギング設定項目群ＤＢ７２には、さらに、関連デバイスの夫々について、先頭ＸＹ依存性と軸番号依存性とが個々のデバイスの属性情報として登録されている。図７の下部に示すデータ構造例によれば、先頭ＸＹをα、軸番号をβ＋１とした場合のデバイスアドレスの数字部分に加算される値が夫々登録されている。例えば「Ｙ１０」は、先頭ＸＹがα、軸番号がβ＋１に変更されたとき、デバイスアドレス変更後は「Ｙ（１０＋α＋β）」となることが分かる。また、「Ｙ０」、「Ｘ０」および「Ｕ０￥Ｇ８０４」は、デバイスアドレスは軸番号に依存しないことが分かる。また、「Ｕ０￥Ｇ８０４」は、オフセットとして先頭ＸＹの値αが１６進法表記の値「１０」で除した値が加算されることが分かる。 Further, in the logging setting item group DB 72, the head XY dependency and the axis number dependency are registered as attribute information of each device for each related device. According to the data structure example shown in the lower part of FIG. 7, values to be added to the numeric part of the device address when the head XY is α and the axis number is β + 1 are registered. For example, “Y10” becomes “Y (10 + α + β)” after the device address is changed when the head XY is changed to α and the axis number is changed to β + 1. It can also be seen that “Y0”, “X0”, and “U0 ¥ G804” do not depend on the axis number for the device address. In addition, it is understood that “U0 ¥ G804” is added with a value obtained by dividing the value α of the head XY by the value “10” in hexadecimal notation as an offset.
　関連項目群抽出部７１は、ユニット情報取得部７０が取得したユニット形名を検索キーとしてロギング設定項目群ＤＢ７２を検索して、当該ユニット形名に属するロギング設定項目を抽出する。 The related item group extraction unit 71 searches the logging setting item group DB 72 using the unit type name acquired by the unit information acquisition unit 70 as a search key, and extracts the logging setting item belonging to the unit type name.
　関連項目群表示／選択部７３は、関連項目群抽出部７１が抽出した項目を出力装置５８に表示して、表示した項目のうちユーザが希望する項目の選択入力を受け付ける。 The related item group display / selection unit 73 displays the items extracted by the related item group extraction unit 71 on the output device 58, and receives selection input of items desired by the user among the displayed items.
　オフセット反映部７４は、用いて選択されたロギング設定項目に属する関連デバイスの夫々に対して当該関連デバイスの夫々の属性情報とユニット情報取得部７０が取得した先頭ＸＹとロギング対象の軸番号とを反映させることによって、個々の関連デバイスの変更後のデバイスアドレスを算出する。 The offset reflection unit 74 displays the attribute information of each related device, the head XY acquired by the unit information acquisition unit 70, and the axis number of the logging target for each related device belonging to the logging setting item selected by using the offset reflection unit 74. By reflecting, the device address after the change of each related device is calculated.
　ロギング設定出力部７５は、オフセット反映部７４が算出した個々の関連デバイスの変更後のデバイスアドレスをロギング対象に設定したロギング設定データＤ１を出力する。ロギング設定データＤ１は、例えばＲＡＭ５２や外部記憶装置５５に出力された後、ＣＰＵユニット２へ設定される。 The logging setting output unit 75 outputs logging setting data D1 in which the device address after the change of each related device calculated by the offset reflection unit 74 is set as a logging target. The logging setting data D1 is set to the CPU unit 2 after being output to the RAM 52 or the external storage device 55, for example.
　図８は、プログラミング装置５を使用して実現する本発明の実施の形態のロギング設定方法を説明するフローチャートである。 FIG. 8 is a flowchart for explaining the logging setting method according to the embodiment of the present invention realized by using the programming device 5.
　図８に示すように、まず、ユーザがデバイスを指定する入力を行なう（ステップＳ１）。デバイスの指定は、例えば図９に示すようにユーザプログラム６１の編集画面から選択できるようになっていると便利である。図９に示すユーザプログラム編集画面の例では、「ＳＥＴ　Ｙ３２」にカーソルを合わせて所定のクリック動作を行うと、「ロギング設定項目に追加」、「ロギング設定項目に関連項目追加」を含むプルダウンメニューが現われる。そして、「ロギング設定項目に関連項目追加」を選択すると、プログラミング装置５はデバイス「Ｙ３２」の指定入力を認識する。なお、「ロギング設定項目に追加」を選択すると、後述のステップが実行されることなく「Ｙ３２」が単独でロギング対象として指定入力される。図１０は、「Ｙ３２」が単独でロギング対象として指定された場合のロギング設定画面の例を示す図である。図示するように、ロギング対象として「Ｙ３２」のみがリストされている。 As shown in FIG. 8, first, the user performs input for designating a device (step S1). For example, as shown in FIG. 9, it is convenient that the device can be specified from the editing screen of the user program 61. In the example of the user program editing screen shown in FIG. 9, a pull-down menu including “Add to logging setting item” and “Add related item to logging setting item” when the cursor is moved to “SET Y32” and a predetermined click operation is performed. Appears. When “Add related item to logging setting item” is selected, the programming device 5 recognizes the designation input of the device “Y32”. When “add to logging setting item” is selected, “Y32” is independently designated and input as a logging target without performing the steps described below. FIG. 10 is a diagram illustrating an example of the logging setting screen when “Y32” is designated as a logging target alone. As shown in the figure, only “Y32” is listed as a logging target.
　ステップＳ１でデバイスの選択入力がなされると、ユニット情報取得部７０は、選択されたデバイスを使用するサブユニットのユニット形名および先頭ＸＹが記述されたユニット情報を取得する（ステップＳ２）。関連項目群抽出部７１は、取得したユニット形名を検索キーとしてロギング設定項目群ＤＢ７２を検索して、ロギング設定項目群の一覧を取得する（ステップＳ３）。また、関連項目群抽出部７１は、ロギング設定項目群ＤＢ７２に登録されている関連デバイスの属性情報と、入力されたデバイスおよび取得した先頭ＸＹとに基づいて軸番号を算出する（ステップＳ４）。 When a device selection input is made in step S1, the unit information acquisition unit 70 acquires unit information in which the unit type name of the subunit that uses the selected device and the head XY are described (step S2). The related item group extraction unit 71 searches the logging setting item group DB 72 using the acquired unit type name as a search key, and acquires a list of logging setting item groups (step S3). Further, the related item group extraction unit 71 calculates an axis number based on the attribute information of the related device registered in the logging setting item group DB 72, the input device, and the acquired head XY (step S4).
　関連項目群表示／選択部７３は、取得したロギング設定項目群を一覧表示して、ロギング設定項目の選択入力を促す（ステップＳ５）。図１１は、ロギング設定項目群の一覧表示画面の例を示す図である。この図では、ロギング設定項目群のほか、取得したユニット形名、および取得した先頭ＸＹが表示されている。また、ロギング設定項目群のうちの「ブロック始動制御」がアクティブ表示されている。 The related item group display / selection unit 73 displays the acquired logging setting item group as a list, and prompts the selection input of the logging setting item (step S5). FIG. 11 is a diagram illustrating an example of a list display screen of a logging setting item group. In this figure, in addition to the logging setting item group, the acquired unit model name and the acquired head XY are displayed. In addition, “block start control” in the logging setting item group is actively displayed.
　ユーザがロギング設定項目を選択すると（ステップＳ６）、オフセット反映部７４は、選択されたロギング設定項目の関連デバイス群を構成する関連デバイスに先頭ＸＹと算出した軸番号にかかるオフセットを反映してデバイスアドレスを変更する（ステップＳ７）。ロギング設定出力部７５は、デバイスアドレス変更後の各関連デバイスをロギング対象としたロギング設定データを出力し（ステップＳ８）、ロギング設定が完了する。図１２は、デバイスアドレス変更後の関連デバイスの一覧表示画面の例である。図示するように、「ブロック始動制御」にかかる関連デバイスのアドレスＹ１０、Ｙ０、Ｘ０、Ｘ１０、ＸＣ、Ｘ１４、Ｘ８、Ｕ０￥Ｇ８０４が夫々、Ｙ３２、Ｙ２０、Ｘ２０、Ｘ３２、Ｘ２Ｅ、Ｘ３６、Ｘ２Ａ、Ｕ２￥Ｇ８０４に変更されて一覧表示されている。ユーザがこれでロギング対象を確定すると、Ｙ３２、Ｙ２０、Ｘ２０、Ｘ３２、Ｘ２Ｅ、Ｘ３６、Ｘ２Ａ、Ｕ２￥Ｇ８０４をロギング対象とするロギング設定データが出力される。なお、当該一覧表示からユーザがさらにロギング対象を取捨選択できるように構成してもよい。 When the user selects a logging setting item (step S6), the offset reflecting unit 74 reflects the offset relating to the calculated head number XY and the axis number calculated on the related device constituting the related device group of the selected logging setting item. The address is changed (step S7). The logging setting output unit 75 outputs logging setting data targeting each related device after changing the device address (step S8), and the logging setting is completed. FIG. 12 is an example of a related device list display screen after the device address is changed. As shown in the figure, the addresses Y10, Y0, X0, X10, XC, X14, X8, U0 ¥ G804 of the related devices related to “block start control” are Y32, Y20, X20, X32, X2E, X36, X2A, respectively. The list is changed to U2 \ G804. When the user determines the logging target, logging setting data for Y32, Y20, X20, X32, X2E, X36, X2A, U2 \ G804 is output. In addition, you may comprise so that a user can further select logging object from the said list display.
　図１３は、変更後のデバイス（Ｙ３２、Ｙ２０、Ｘ２０、Ｘ３２、Ｘ２Ｅ、Ｘ３６、Ｘ２Ａ、Ｕ２￥Ｇ８０４）をロギング対象とした場合のインテリジェントユニット３の動作例を説明する図である。図示するように、「ブロック始動制御」にかかるプログラム例の関連デバイスのアドレスが夫々先頭ＸＹと軸番号に応じて適切に変換されたので、図３に示したマニュアル記載の動作例と比較検討してユーザプログラムに誤りがあるか否かを検討することができるようになる。 FIG. 13 is a diagram for explaining an operation example of the intelligent unit 3 when the changed device (Y32, Y20, X20, X32, X2E, X36, X2A, U2 \ G804) is set as a logging target. As shown in the figure, the addresses of the related devices in the program example related to “block start control” were appropriately converted according to the head XY and the axis number, respectively. Therefore, the operation example described in the manual shown in FIG. This makes it possible to examine whether there is an error in the user program.
　なお、以上の説明においては、プログラミング装置５が自動的に軸番号を算出することとしたが、ユーザが軸番号を入力するようにしてもよい。例えば、図７に示したＹ０やＸ０は軸番号に依存しない。従って「Ｙ２０」が選択入力されると、軸番号を特定することができない。このような場合、ユーザによる軸番号の指定が必要となる。 In the above description, the programming device 5 automatically calculates the axis number. However, the user may input the axis number. For example, Y0 and X0 shown in FIG. 7 do not depend on the axis number. Therefore, when “Y20” is selected and input, the axis number cannot be specified. In such a case, it is necessary to specify an axis number by the user.
　また、インテリジェントユニット３の例として複数軸の駆動制御を行う位置決めユニットを取り上げて説明したが、複数の入出力系統を備えるユニット（例えば１つ以上の入力系統（チャネル）のＡ／Ｄ変換を行うＡ／Ｄ変換ユニット）であれば、どのようなユニットであっても本発明の実施の形態を適用することができる。その際、軸番号を入出力系統の識別番号で読み替えて解釈するとよい。 In addition, the positioning unit that performs drive control of a plurality of axes has been described as an example of the intelligent unit 3, but a unit including a plurality of input / output systems (for example, A / D conversion of one or more input systems (channels) is performed. The embodiment of the present invention can be applied to any unit as long as it is an A / D conversion unit. At that time, the axis number may be interpreted as the input / output system identification number.
　また、関連デバイス群はマニュアルに記載されているプログラム例毎に規定されているとして説明したが、関連デバイス群を、プログラムの記載例に限らず、制御動作の典型例毎に規定するようにしてもよい。これによって、マニュアルと動作を比較する場合に限らずユーザがロギング設定項目群データベース７２に登録されている動作にかかる関連デバイスを個々に設定する労力を軽減することができる。 In addition, although the related device group has been described as being defined for each program example described in the manual, the related device group is not limited to the program description example, but is defined for each typical example of the control operation. Also good. Thereby, it is possible to reduce the labor for the user to individually set the related devices related to the operation registered in the logging setting item group database 72, not only when comparing the operation with the manual.
　また、ロギング設定項目群データベース７２は、ユーザによる編集が可能に構成されてもよい。 Also, the logging setting item group database 72 may be configured to be editable by the user.
　また、プログラミング装置５は、ユニット情報リスト６０が編集されたり、サブユニットの装着位置が変更されたことによりＣＰＵユニット２に格納されているユニット情報リスト２４が自動変更されたとき、ユニット情報取得部７０がユニット情報リストの編集または変更を検知して各デバイスについてユニット情報を取得しなおし、プログラミング装置５においてステップＳ３以下の動作を実行することにより、ロギング設定データＤ１を自動で修正するように構成してもよい。このように構成することによって、サブユニットの装着位置を変更する毎にロギング対象のデバイスアドレスを変更する手間を軽減することができる。 Further, when the unit information list 60 stored in the CPU unit 2 is automatically changed by editing the unit information list 60 or changing the mounting position of the subunit, the programming device 5 70 is configured to automatically correct the logging setting data D1 by detecting the editing or changing of the unit information list, reacquiring unit information for each device, and executing the operation in step S3 and subsequent steps in the programming device 5. May be. With this configuration, it is possible to reduce the trouble of changing the logging target device address every time the subunit mounting position is changed.
　以上述べたように、本発明の実施の形態によれば、ユニット毎に制御動作の典型例の名称と当該制御動作にかかる関連デバイス群との対応付けを、関連デバイス群を構成するデバイス毎の先頭ＸＹ依存性とともに記憶しているロギング設定項目群データベース７２を備え、ロギング対象のデバイスを使用するユニットにかかる制御動作の典型例の名称の一覧を前記ロギング設定項目群データベース７２から抽出し、前記抽出した名称の一覧のうちのユーザにより選択された一つに対応づけられている関連デバイス群を構成する夫々の関連デバイスのアドレスを先頭ＸＹ依存性に基づいて変更するように構成したので、ユーザは選択したデバイスに関連するデバイスを一括してロギング設定することができるので、可及的に簡単にロギング設定を行うことができるようになる。また、ユーザプログラム２５中では記述されていないインテリジェントユニット３が中間データ格納領域として使用するデバイスまでロギング対象に設定することができる。 As described above, according to the embodiment of the present invention, the correspondence between the name of the typical example of the control operation and the related device group related to the control operation for each unit is set for each device constituting the related device group. A logging setting item group database 72 stored together with the head XY dependency; a list of typical names of control operations relating to units using the logging target device is extracted from the logging setting item group database 72; Since the address of each related device constituting the related device group associated with one selected by the user from the extracted list of names is changed based on the top XY dependency, the user Allows you to configure logging settings for all devices related to the selected device. So it is possible to perform. In addition, the intelligent unit 3 not described in the user program 25 can be set as a logging target even for a device used as an intermediate data storage area.
　以上のように、本発明にかかるロギング設定装置およびロギング設定方法は、ＰＬＣのロギング設定を行うロギング設定装置およびロギング設定方法に適用して好適である。 As described above, the logging setting device and the logging setting method according to the present invention are suitable for application to a logging setting device and a logging setting method for performing PLC logging settings.
