　以下に、本発明にかかるプログラマブル表示器およびプログラマブル表示器の表示方法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 programmable display and a display method of the programmable display according to the present invention will be described in detail based on the drawings. Note that the present invention is not limited to the embodiments.
実施の形態１．
　図１は、本発明の実施の形態１にかかるプログラマブル表示器１およびＰＬＣシステム２が接続されている様子を示す図である。図２は、本発明の実施の形態１にかかるプログラマブル表示器１の機能ブロックの構成を示す図である。プログラマブル表示器１は、表示部１０、入力部１１、拡縮処理部１２、例外処理部１３、および描画データ保持部１４を備える。 Embodiment 1 FIG.
FIG. 1 is a diagram illustrating a state in which a programmable display 1 and a PLC system 2 according to a first embodiment of the present invention are connected. FIG. 2 is a diagram illustrating a configuration of functional blocks of the programmable display device 1 according to the first embodiment of the present invention. The programmable display device 1 includes a display unit 10, an input unit 11, an enlargement / reduction processing unit 12, an exception processing unit 13, and a drawing data holding unit 14.
　画面を介してユーザに情報を視覚的に提供する表示部１０およびユーザのタッチ操作などを受け付ける入力部１１は、例えばタッチパネル式のモニタとして一体化されている。表示部１０の画面解像度は、例えばＶＧＡなどのように予め定められている。ユーザは例えば、ＰＣ３上の画面作成エディタなどを用いて１つ以上のオブジェクトを含み表示部１０の画面解像度より高い画面解像度で作成された、ＰＬＣシステム２の構成図などの描画データを作成し、有線或いは無線により当該描画データを描画データ保持部１４にダウンロードする。描画データ保持部１４は、ユーザが作成した描画データを保持している。描画データが描画データ保持部１４にダウンロードされた後は、ＰＣ３はプログラマブル表示器１に接続されている必要はない。 The display unit 10 that visually provides information to the user via the screen and the input unit 11 that receives the user's touch operation and the like are integrated as, for example, a touch panel monitor. The screen resolution of the display unit 10 is predetermined such as VGA, for example. For example, the user creates drawing data such as a configuration diagram of the PLC system 2 that includes one or more objects and is created with a screen resolution higher than the screen resolution of the display unit 10 using a screen creation editor on the PC 3, The drawing data is downloaded to the drawing data holding unit 14 by wire or wireless. The drawing data holding unit 14 holds drawing data created by the user. After the drawing data is downloaded to the drawing data holding unit 14, the PC 3 does not need to be connected to the programmable display 1.
　図３は、本実施の形態にかかるプログラマブル表示器１の動作フローチャートを示す図である。まず、表示部１０には、図４に示すように最大倍率である１００％表示で各オブジェクトが表示されている（ステップＳ１０１）。ここで、オブジェクトとは、ＰＬＣシステム２のスイッチ、あるいはＰＬＣシステム２が制御しているロボットなどの構成要素の１つずつを示す。図４では、オブジェクト４０がオブジェクト５１および５２により挟まれて示されている。 FIG. 3 is a diagram showing an operation flowchart of the programmable display 1 according to the present embodiment. First, as shown in FIG. 4, each object is displayed on the display unit 10 in a 100% display that is the maximum magnification (step S101). Here, the object indicates one each of the constituent elements such as a switch of the PLC system 2 or a robot controlled by the PLC system 2. In FIG. 4, the object 40 is shown sandwiched between the objects 51 and 52.
　次に、ユーザが入力部１１を介して希望の倍率で画面の縮小を指示する（ステップＳ１０２）。ユーザの画面縮小指示は、拡縮処理部１２および例外処理部１３に伝えられる。拡縮処理部１２は、ユーザの画面縮小指示が示した倍率に従って、描画データ保持部１４に保持されている描画データを縮小して表示する描画データを作成する。この際、例外処理部１３はユーザが指示した縮小率が所定の閾値以下になっているか否かを判定する（ステップＳ１０３）。所定の閾値は、ここでは例えば６０％とする。 Next, the user instructs reduction of the screen at a desired magnification through the input unit 11 (step S102). The user's screen reduction instruction is transmitted to the enlargement / reduction processing unit 12 and the exception processing unit 13. The enlargement / reduction processing unit 12 generates drawing data to be displayed by reducing the drawing data held in the drawing data holding unit 14 according to the magnification indicated by the user's screen reduction instruction. At this time, the exception processing unit 13 determines whether or not the reduction rate designated by the user is equal to or less than a predetermined threshold (step S103). The predetermined threshold is 60% here, for example.
　ユーザが指示した縮小率が例えば５０％であって所定の閾値（６０％）以下の場合（ステップＳ１０３：Ｙｅｓ）は、例外処理部１３はさらに、描画データ保持部１４に保持されている描画データの特定のオブジェクトにユーザが予め設定した属性（プロパティ）が設定されているか否かをチェックする。ユーザが予め設定した属性とは、例えばこのオブジェクトは、縮小率が所定の値以下の場合は表示しないなどという属性である。このような非表示の属性は、描画データ保持部１４に保持されている描画データをユーザがＰＣ３上の画面作成エディタなどを用いて作成したときに重要度の低いと考えられるオブジェクトなど所望のオブジェクトに既に付与されている。そして、例えば図４のオブジェクト４０にそのような属性が付与されている場合は、例外処理部１３は非表示の属性が設定されているオブジェクトを例外オブジェクト情報として求める。拡縮処理部１２は、例外オブジェクト情報に基づいて、描画データの縮小処理において、オブジェクト４０は非表示にしてそれ以外のオブジェクトはユーザが指示した縮小率で表示する描画データを作成して、図５に示すような画面を表示部１０に表示させる（ステップＳ１０４）。これにより、重要度の低いオブジェクトを非表示にした縮小画面を作成することが可能となり、ユーザにとって見通しの良い画面とすることができる。 When the reduction rate designated by the user is, for example, 50% and is equal to or less than a predetermined threshold (60%) (step S103: Yes), the exception processing unit 13 further draws the drawing data held in the drawing data holding unit 14. It is checked whether or not an attribute (property) preset by the user is set for the specific object. The attribute set in advance by the user is, for example, an attribute that this object is not displayed when the reduction ratio is a predetermined value or less. Such a non-display attribute is a desired object such as an object considered to be less important when the user creates drawing data held in the drawing data holding unit 14 by using a screen creation editor on the PC 3. Has already been granted. For example, when such an attribute is given to the object 40 in FIG. 4, the exception processing unit 13 obtains an object for which the non-display attribute is set as exception object information. Based on the exception object information, the enlargement / reduction processing unit 12 creates drawing data in which the object 40 is not displayed and the other objects are displayed at the reduction rate designated by the user in the drawing data reduction processing. Is displayed on the display unit 10 (step S104). As a result, it is possible to create a reduced screen in which objects with low importance are not displayed, and the screen can be easily viewed by the user.
　ユーザが指示した縮小率が所定の閾値（６０％）より大きい場合（ステップＳ１０３：Ｎｏ）は、例外処理部１３は拡縮処理部１２の処理に関与しない。その結果、拡縮処理部１２は、描画データ保持部１４に保持されている描画データをユーザが指示した縮小率に従って縮小して表示する描画データを作成して表示部１０に表示させる（ステップＳ１０５）。 When the reduction rate designated by the user is larger than a predetermined threshold (60%) (step S103: No), the exception processing unit 13 is not involved in the processing of the scaling processing unit 12. As a result, the enlargement / reduction processing unit 12 creates drawing data to be displayed by reducing the drawing data held in the drawing data holding unit 14 in accordance with the reduction ratio designated by the user and displays the drawing data on the display unit 10 (step S105). .
　上記ステップＳ１０３では、ユーザが指示した縮小率が所定の閾値以下になっているか否かを判定するとして説明したが、ユーザが指示した（縮小率に対応する）オブジェクトの辺の表示サイズが所定の長さ以下になっているか否かで判断するようにしてもかまわない。また、上記では縮小率に対して閾値を設定したが、拡大率に対して閾値を設定して、ユーザが表示・非表示についての属性を付与しておいてもかまわない。 In step S103, it has been described that it is determined whether or not the reduction ratio designated by the user is equal to or less than a predetermined threshold. However, the display size of the side of the object designated by the user (corresponding to the reduction ratio) is predetermined. You may make it judge by whether it is below the length. In the above description, the threshold is set for the reduction ratio, but the threshold may be set for the enlargement ratio, and the user may be given an attribute for display / non-display.
　縮小率或いは拡大率で所定のオブジェクトに属性を付与するなどして指定する場合は、画面作成者であるユーザが直感的かつ容易に表示・非表示を決定することが可能である。また、縮小処理後或いは拡大処理後の辺の長さに基づいて表示・非表示指定することを可能にすると、具体的な画面上のサイズ（画面上のピクセル数）で判断基準を表現することが可能となり、ユーザが画面上で意図した大きさで動作可否を決めることが容易となる。 When specifying by assigning an attribute to a predetermined object at a reduction ratio or an enlargement ratio, the user who is the screen creator can intuitively and easily determine display / non-display. Also, if display / non-display can be specified based on the length of the side after reduction processing or enlargement processing, the judgment criteria can be expressed by a specific size on the screen (number of pixels on the screen). Therefore, it becomes easy for the user to decide whether or not to operate in the size intended on the screen.
　たとえば、画面上で、例えば一辺が５０ピクセル以上のサイズを有していなければ誤操作が起きやすい配置のスイッチがある場合、縮小率或いは拡大率を指定して表示・非表示を決定する場合は、オブジェクトのサイズからピクセル数を算出して決定する必要があるが、あらかじめピクセル数を用いて閾値を指定しておけばそのような手間が不要となり、ユーザが計算する手間を削減することが可能となる。 For example, on the screen, for example, if there is a switch with an arrangement in which an erroneous operation is likely to occur unless one side has a size of 50 pixels or more, when specifying display / non-display by specifying a reduction ratio or enlargement ratio, It is necessary to calculate and determine the number of pixels from the size of the object, but if you specify the threshold value using the number of pixels in advance, such effort is unnecessary, and it is possible to reduce the effort that the user calculates Become.
　また、上記では、閾値以下の縮小率のときに、重要度の低いと考えられるオブジェクトを非表示にするとしたが、これに限らず、当該オブジェクトの表示時の透明度（透過度）を高める、或いは単純化したアイコンなどに記号化にして表示するというバリエーションも考えられる。 Further, in the above description, an object that is considered to be low in importance when the reduction ratio is equal to or less than the threshold value is hidden. However, the present invention is not limited to this, and the transparency (transparency) at the time of displaying the object is increased, or There can be a variation in which a simplified icon is displayed as a symbol.
　また、ユーザが画面の拡大を指示した場合は、表示部１０の画面に表示されるオブジェクトの一部あるいは全部に対して必要な情報を付加して表示するようにしてもよい。これにより、画面を拡大していくとオブジェクトのより詳しい情報が表示されるようにすることが可能となる。 Further, when the user gives an instruction to enlarge the screen, necessary information may be added to some or all of the objects displayed on the screen of the display unit 10 and displayed. As a result, when the screen is enlarged, more detailed information on the object can be displayed.
実施の形態２．
　本発明の実施の形態２にかかるプログラマブル表示器１の機能ブロックの構成は図２と同様であるが、その機能および動作は以下の点で異なる。図６は、本発明の実施の形態２にかかるプログラマブル表示器１の動作フローチャートを示す図である。 Embodiment 2. FIG.
Although the structure of the functional block of the programmable display 1 concerning Embodiment 2 of this invention is the same as that of FIG. 2, the function and operation | movement differ by the following points. FIG. 6 is an operation flowchart of the programmable display 1 according to the second exemplary embodiment of the present invention.
　まず、表示部１０には、図７に示すように縮小表示で各オブジェクトが表示されている（ステップＳ２０１）。図７では、オブジェクト４１がオブジェクト５１および５２により挟まれて示されている。 First, each object is displayed in a reduced display on the display unit 10 as shown in FIG. 7 (step S201). In FIG. 7, the object 41 is shown sandwiched between the objects 51 and 52.
　次に、ユーザが入力部１１を介して希望の倍率で画面の拡大を指示する（ステップＳ２０２）。ユーザの画面拡大指示は、拡縮処理部１２および例外処理部１３に伝えられる。拡縮処理部１２は、ユーザの画面拡大指示が示した倍率に従って、描画データ保持部１４に保持されている描画データを拡大して表示する描画データを作成する。この際、例外処理部１３は、描画データ保持部１４に保持されている描画データの特定のオブジェクトにユーザが予め設定した属性（プロパティ）が設定されているか否かをチェックする（ステップＳ２０３）。ユーザが予め設定した属性とは、例えばこのオブジェクトは、目印のようなものとして拡大縮小に追従せずそのままのサイズを変更しないで維持したまま表示する（拡大しない）などという属性である。このようなサイズ維持の属性は、描画データ保持部１４に保持されている描画データをユーザがＰＣ３上の画面作成エディタなどを用いて作成したときに、例えば、重要度が低い、或いは中心的な存在であると考えられるオブジェクトなどの所望のオブジェクトに既に付与されている。 Next, the user instructs enlargement of the screen at a desired magnification via the input unit 11 (step S202). The user's screen enlargement instruction is transmitted to the enlargement / reduction processing unit 12 and the exception processing unit 13. The enlargement / reduction processing unit 12 creates drawing data for displaying the enlarged drawing data held in the drawing data holding unit 14 in accordance with the magnification indicated by the user's screen enlargement instruction. At this time, the exception processing unit 13 checks whether or not an attribute (property) set in advance by the user is set in a specific object of the drawing data held in the drawing data holding unit 14 (step S203). The attribute set in advance by the user is, for example, an attribute in which the object is displayed as a mark (not enlarged) without following the enlargement / reduction and maintaining the same size without changing. Such a size maintenance attribute is, for example, less important or central when the user creates drawing data held in the drawing data holding unit 14 using a screen creation editor on the PC 3. Already assigned to a desired object, such as an object that is considered to exist.
　そして、例えば図７のオブジェクト４１にそのような属性が付与されている場合（ステップＳ２０３：Ｙｅｓ）は、例外処理部１３は、サイズ維持の属性が設定されているオブジェクトを例外オブジェクト情報として求める。拡縮処理部１２は、例外オブジェクト情報に基づいて描画データの拡大処理において、図７におけるオブジェクト４１のサイズを維持し、それ以外のオブジェクトはユーザが指示した拡大率で表示するような描画データを作成して、図８に示すような画面を表示部１０に表示させる（ステップＳ２０４）。この場合、図７におけるオブジェクト４１と図８におけるオブジェクト４１の中心座標などの表示位置も維持する。 For example, when such an attribute is assigned to the object 41 of FIG. 7 (step S203: Yes), the exception processing unit 13 obtains an object for which the size maintenance attribute is set as exception object information. The enlargement / reduction processing unit 12 maintains the size of the object 41 in FIG. 7 in the drawing data enlargement process based on the exception object information, and creates drawing data that displays the other objects at the enlargement rate designated by the user. Then, a screen as shown in FIG. 8 is displayed on the display unit 10 (step S204). In this case, the display positions such as the center coordinates of the object 41 in FIG. 7 and the object 41 in FIG. 8 are also maintained.
　ユーザが予め設定した属性（プロパティ）が設定されていない場合（ステップＳ２０３：Ｎｏ）は、例外処理部１３は拡縮処理部１２の処理に関与しない。その結果、拡縮処理部１２は、描画データ保持部１４に保持されている描画データをユーザが指示した拡大率に従って拡大して表示する描画データを作成して表示部１０に表示させる（ステップＳ２０５）。 When the attribute (property) preset by the user is not set (step S203: No), the exception processing unit 13 is not involved in the processing of the enlargement / reduction processing unit 12. As a result, the enlargement / reduction processing unit 12 creates drawing data to be displayed by enlarging the drawing data held in the drawing data holding unit 14 in accordance with the enlargement ratio designated by the user and displays the drawing data on the display unit 10 (step S205). .
　なお、上記では、拡大時にオブジェクト４１のサイズを維持するとしたが、縮小時にサイズを維持するようにしてもよい。この場合は、サイズを維持した場合に他のオブジェクトとオーバーラップが生ずる可能性があるので、中心座標あるいは四隅の角の座標などを維持しつつ、同じサイズのまま他のオブジェクトの前面または背面に透過性を持たせるなどして表示するようにしてもよい。 In the above description, the size of the object 41 is maintained at the time of enlargement, but the size may be maintained at the time of reduction. In this case, there is a possibility of overlapping with other objects when the size is maintained. Therefore, while maintaining the center coordinates or the coordinates of the corners of the four corners, the same size is maintained on the front or back of other objects. You may make it display by giving transparency.
　本実施の形態によれば、例えば案内図の現在地を示すマーカや、その座標に対する注意事項の表示などを拡大縮小にかかわらず表示させることができ、拡大縮小した際の表示位置や、見易さなどをユーザが考慮して画面作成エディタなどを用いて描画データを作成する必要がなくなり、マーカとなるオブジェクトを目立たせることが可能となるので、ユーザの負担を低減しつつ、プログラマブル表示器における画面作成の自由度を向上させることが可能となる。 According to the present embodiment, for example, a marker indicating the current location of a guide map and a display of a caution for the coordinates can be displayed regardless of enlargement / reduction. It is no longer necessary to create drawing data using a screen creation editor etc. considering the user, etc., and it becomes possible to make the marker object stand out, so the screen on the programmable display can be reduced while reducing the burden on the user It becomes possible to improve the freedom of creation.
　ユーザの指示に従って、画面解像度を自由に変更する場合、通常は、画面全体に対して等しく拡大、縮小を行う。しかし、画面全体に対して等しく拡大縮小を行うと、本来表示したいオブジェクトが見にくくなるなど視認性に問題が出る場合がある。これに対して、上記実施の形態１および２によればこのような視認性の問題を回避することが可能となる。 When changing the screen resolution freely according to the user's instructions, normally, the entire screen is enlarged and reduced equally. However, if the entire screen is scaled equally, there may be a problem in visibility, such as making it difficult to see the object that is originally intended to be displayed. On the other hand, according to the first and second embodiments, it is possible to avoid such a visibility problem.
実施の形態３．
　本発明の実施の形態３にかかるプログラマブル表示器１の機能ブロックの構成は図２と同様であるが、その機能および動作は以下の点で異なる。図９は、本発明の実施の形態３にかかるプログラマブル表示器１の動作フローチャートを示す図である。 Embodiment 3 FIG.
Although the structure of the functional block of the programmable display 1 concerning Embodiment 3 of this invention is the same as that of FIG. 2, the function and operation | movement differ by the following points. FIG. 9 is a diagram illustrating an operation flowchart of the programmable display device 1 according to the third embodiment of the present invention.
　まず、表示部１０には、図１０に示すように拡大表示で各オブジェクトが表示されている（ステップＳ３０１）。図１０では、オブジェクト４２がオブジェクト５１および５２により挟まれて示されている。 First, each object is displayed in an enlarged display on the display unit 10 as shown in FIG. 10 (step S301). In FIG. 10, the object 42 is shown sandwiched between the objects 51 and 52.
　次に、ユーザが入力部１１を介して希望の倍率で画面の縮小を指示する（ステップＳ３０２）。ユーザの画面縮小指示は、拡縮処理部１２および例外処理部１３に伝えられる。拡縮処理部１２は、ユーザの画面縮小指示が示した倍率に従って、描画データ保持部１４に保持されている描画データを縮小して表示する描画データを作成する。この際、例外処理部１３はユーザが指示した縮小率にすると特定のオブジェクトの例えば一辺のサイズが所定の閾値以下になっているか否かを判定する（ステップＳ３０３）。所定の閾値は、ここでは例えば５０ピクセルとする。 Next, the user instructs the reduction of the screen at a desired magnification via the input unit 11 (step S302). The user's screen reduction instruction is transmitted to the enlargement / reduction processing unit 12 and the exception processing unit 13. The enlargement / reduction processing unit 12 generates drawing data to be displayed by reducing the drawing data held in the drawing data holding unit 14 according to the magnification indicated by the user's screen reduction instruction. At this time, the exception processing unit 13 determines whether, for example, the size of one side of the specific object is equal to or smaller than a predetermined threshold when the reduction ratio specified by the user is set (step S303). Here, the predetermined threshold value is, for example, 50 pixels.
　ユーザが指示した縮小率にすると特定のオブジェクトの一辺のサイズが閾値である５０ピクセル以下となる場合（ステップＳ３０３：Ｙｅｓ）は、例外処理部１３はさらに、描画データ保持部１４に保持されている描画データの当該特定のオブジェクトにユーザが予め設定した属性（プロパティ）が設定されているか否かをチェックする。ユーザが予め設定した属性とは、例えばこのオブジェクトは、誤操作されると問題があるなどの属性である。このような縮小時操作不可の属性は、描画データ保持部１４に保持されている描画データをユーザがＰＣ３上の画面作成エディタなどを用いて作成したときに誤操作されると問題があると考えられるオブジェクトなど所望のオブジェクトに既に付与されている。そして、例えば図１０のオブジェクト４２にそのような属性が付与されている場合は、例外処理部１３は、縮小時操作不可の属性が設定されているオブジェクトを例外オブジェクト情報として求める。拡縮処理部１２は描画データの縮小処理をそのまま実行する。従って、拡縮処理部１２はオブジェクト４２も他のオブジェクトと同様にユーザが指示した縮小率で表示する描画データを作成して、図１１に示すような画面を表示部１０に表示させる。しかし、図１１の状態において、拡縮処理部１２は、例外オブジェクト情報に基づいてユーザが画面のオブジェクト４２にタッチしても入力部１１にその操作を受け付けない状態にする（ステップＳ３０４）。ユーザが指示した縮小率でも特定のオブジェクトの一辺のサイズが閾値より大きい場合（ステップＳ３０３：Ｎｏ）は、拡縮処理部１２は、描画データ保持部１４に保持されている描画データをユーザが指示した縮小率に従って縮小して表示する描画データを作成して表示部１０に表示させるだけで、オブジェクト４２は操作可能な状態としておく。 When the reduction ratio specified by the user is equal to or less than the threshold value of 50 pixels (step S303: Yes), the exception processing unit 13 is further held in the drawing data holding unit 14. It is checked whether or not an attribute (property) set in advance by the user is set for the specific object of the drawing data. The attribute set in advance by the user is, for example, an attribute that this object has a problem if it is erroneously operated. Such an attribute that cannot be operated at the time of reduction is considered to be problematic if a user erroneously operates drawing data held in the drawing data holding unit 14 using a screen creation editor on the PC 3 or the like. Already assigned to a desired object such as an object. For example, when such an attribute is given to the object 42 in FIG. 10, the exception processing unit 13 obtains, as exception object information, an object for which an attribute that cannot be operated at the time of reduction is set. The enlargement / reduction processing unit 12 executes the drawing data reduction process as it is. Accordingly, the enlargement / reduction processing unit 12 creates drawing data for the object 42 to be displayed at the reduction rate designated by the user in the same manner as other objects, and causes the display unit 10 to display a screen as shown in FIG. However, in the state shown in FIG. 11, the enlargement / reduction processing unit 12 sets the input unit 11 to not accept the operation even if the user touches the object 42 on the screen based on the exception object information (step S304). If the size of one side of a specific object is larger than the threshold value even at the reduction rate specified by the user (step S303: No), the enlargement / reduction processing unit 12 has indicated the drawing data held in the drawing data holding unit 14 by the user The object 42 is set in an operable state simply by creating drawing data to be displayed in a reduced size according to the reduction ratio and displaying it on the display unit 10.
　上記のステップＳ３０３では、ユーザが指示した縮小率にしたときの特定のオブジェクトの一辺のサイズが所定の閾値以下になっているか否かを判定するとして説明したが、ユーザが指示した縮小率が所定の閾値以下になっているか否かで判断するようにしてもかまわない。 In step S303 described above, it has been described that it is determined whether or not the size of one side of a specific object when the reduction ratio specified by the user is equal to or smaller than a predetermined threshold. However, the reduction ratio specified by the user is predetermined. The determination may be made based on whether or not it is less than the threshold value.
　ステップＳ３０４のように、特定のオブジェクトについての与えられた縮小率や当該縮小率にしたときのオブジェクトの一辺のサイズなどに基づいて、操作を不可能に設定することにより特定のオブジェクトの所定のサイズ以下での操作を禁止することが可能となる。従って、例えば、縮小した画面で誤って隣のボタンを押してしまったりすることを防ぐことが可能となる。 As in step S304, a predetermined size of the specific object is set by setting the operation to be impossible based on a given reduction ratio for the specific object, the size of one side of the object when the reduction ratio is set, or the like. The following operations can be prohibited. Therefore, for example, it is possible to prevent an adjacent button from being accidentally pressed on a reduced screen.
　解像度を自由に変更する場合、画面全体に対して等しく拡大、縮小を行う必要がある。そして、画面全体に対して等しく縮小を行うと、意図しないところにタッチすることで誤操作が発生する危険性があるが、本実施の形態にかかるプログラマブル表示器１によれば、このような危険を回避することが可能となる。 When changing the resolution freely, it is necessary to enlarge and reduce the entire screen equally. If the entire screen is reduced equally, there is a risk of erroneous operation caused by touching an unintended place. However, according to the programmable display 1 according to the present embodiment, such a risk may occur. It can be avoided.
　なお、上記においては、縮小率が所定の閾値以下となった場合や当該縮小率にしたときの特定のオブジェクトの一辺のサイズが所定の閾値以下になった場合に、操作不可の設定をするとして説明したが、特定のオブジェクトが所定のサイズ以上となった場合、あるいは所定の拡大率以上となった場合に操作不可とするようにすることも可能である。 In the above, when the reduction rate is equal to or less than a predetermined threshold, or when the size of one side of a specific object at the reduction rate is equal to or less than the predetermined threshold, the operation is disabled. As described above, it is also possible to make the operation impossible when a specific object exceeds a predetermined size or when a specific enlargement ratio is exceeded.
実施の形態４．
　実施の形態３のステップＳ３０４において、オブジェクト４２を操作不能に設定したが、図１１の画面の状態において、オブジェクト４２を操作可能にするようにしてもかまわない。具体的には、実施の形態３において、ユーザがＰＣ３上の画面作成エディタなどを用いて描画データを作成したときに、誤操作されると問題があると考えられるオブジェクトに上記した属性を付与したときに、同時にユーザが当該オブジェクトを含んだ近傍領域を設定してもよい。具体的には、例えば、ユーザはオブジェクト４２の３倍の大きさの範囲を近傍領域として設定する。また、近傍領域は誤操作されると問題があると考えられるオブジェクトに上記した属性を付与したときに、初期設定として範囲を規定して与えられていても構わない。近傍領域の情報は、上記属性に付加されており、描画データ保持部１４に描画データと共に保持されているので、例外処理部１３によって、図１２に示すように破線で囲った近傍領域６０として表示部１０に示される。 Embodiment 4 FIG.
In step S304 of the third embodiment, the object 42 is set to be inoperable, but the object 42 may be made operable in the state of the screen in FIG. Specifically, in the third embodiment, when the user creates drawing data using a screen creation editor on the PC 3 or the like, the above-described attribute is given to an object that is considered to have a problem if operated incorrectly. At the same time, the user may set a nearby area including the object. Specifically, for example, the user sets a range that is three times as large as the object 42 as the neighborhood region. Further, when the above-described attribute is given to an object that is considered to have a problem if the neighboring area is erroneously operated, a range may be specified as an initial setting. Since the information on the neighboring area is added to the above attribute and is held together with the drawing data in the drawing data holding unit 14, it is displayed by the exception processing unit 13 as a neighboring area 60 surrounded by a broken line as shown in FIG. Part 10 shows.
　近傍領域６０をユーザがタッチすると、タッチしている間、または、あらかじめ決めておいた時間に、図１３に示すような拡大画面７０が表示される。そして、拡大画面７０の枠内であればオブジェクト４２を操作可能にする。 When the user touches the vicinity area 60, an enlarged screen 70 as shown in FIG. 13 is displayed while the user is touching or at a predetermined time. Then, the object 42 can be operated within the frame of the enlarged screen 70.
　たとえば、タッチとともに近傍領域６０は拡大画面７０のようにオブジェクトとその周囲が拡大され、ユーザの指の接触点８０の移動に伴って拡大画面７０の表示位置が移動する。そして、接触点８０がオブジェクト４２に触れて、指を離したタイミングでオブジェクト４２のスイッチが動作するようにしてもよい。 For example, the object 60 and its surroundings are enlarged in the vicinity area 60 as in the enlarged screen 70 together with the touch, and the display position of the enlarged screen 70 moves as the contact point 80 of the user's finger moves. Then, the switch of the object 42 may be operated when the contact point 80 touches the object 42 and the finger is released.
　また、他の例としては、タッチとともに近傍領域６０は拡大画面７０のようにオブジェクトとその周囲が拡大されて一定時間表示され、拡大画面７０が表示されている間にオブジェクト４２をユーザがタッチすることでオブジェクト４２のスイッチが動作するようにしてもよい。 As another example, the touch and the neighboring area 60 are displayed for a certain period of time with the object and its surroundings enlarged as in the enlarged screen 70, and the user touches the object 42 while the enlarged screen 70 is displayed. Thus, the switch of the object 42 may be operated.
　本実施の形態によれば、縮小画面が表示されて、一旦操作不能となった一部のスイッチなどのオブジェクトの操作が可能となり、表示部１０の画面が表示する情報を増やしたいというニーズと、その画面上でユーザが操作をしたいというニーズを両立させることが可能となる。 According to the present embodiment, there is a need to increase the information displayed on the screen of the display unit 10 because the reduced screen is displayed and the operation of some switches and other objects once disabled becomes possible. It is possible to satisfy both the needs for the user to operate on the screen.
　上記実施の形態１～４における、オブジェクトへの属性の付与は、例えば、ユーザがＰＣ３上の画面作成エディタなどを用いて描画データ保持部１４に保持されることになる描画データを作成したときにユーザが予め設定しておくとして説明した。しかし、事前にそのような属性をユーザが所望のオブジェクトに設定しないでも、ユーザが入力部１１を介して事後的に所望のオブジェクトに対して上述したような属性が付与されている場合と同様な扱いとなるように指示するようにしてもかまわない。 In the first to fourth embodiments, the attribute is given to the object when, for example, the user creates drawing data to be held in the drawing data holding unit 14 using a screen creation editor on the PC 3 or the like. It has been described that the user sets in advance. However, even if the user does not set such an attribute to a desired object in advance, it is the same as the case where the user has given the above-described attribute to the desired object later via the input unit 11. You may instruct it to be handled.
実施の形態５．
　図１４は、本発明の実施の形態５にかかるプログラマブル表示器１およびＰＬＣシステム２が接続されている様子を示す図である。プログラマブル表示器１の構成は図２と同様であるが、ＰＬＣシステム２が例外処理部１３に接続されている。図１５は、本発明の実施の形態５にかかるプログラマブル表示器１の動作フローチャートを示す図である。 Embodiment 5 FIG.
FIG. 14 is a diagram showing a state in which the programmable display 1 and the PLC system 2 according to the fifth embodiment of the present invention are connected. The configuration of the programmable display 1 is the same as that in FIG. 2, but the PLC system 2 is connected to the exception processing unit 13. FIG. 15: is a figure which shows the operation | movement flowchart of the programmable display 1 concerning Embodiment 5 of this invention.
　上述したように、描画データ保持部１４は、表示部１０の画面解像度より高い画面解像度でユーザが作成した描画データを保持している。ユーザが作成した描画データは、例えば図１６の全体図に相当するデータである。 As described above, the drawing data holding unit 14 holds drawing data created by the user at a screen resolution higher than the screen resolution of the display unit 10. The drawing data created by the user is, for example, data corresponding to the overall view of FIG.
　まず、表示部１０は図１６のユーザが作成した全体図を表示している（ステップＳ４０１）。この状態で、ＰＬＣシステム２の特定のユニット、例えば図１６のユニット９１にエラーが発生する（ステップＳ４０２）。ＰＬＣシステム２は、エラーが発生したユニット９１および、所定の画面拡大率などを含んだエラー情報を例外処理部１３に送る。例外処理部１３は、エラーが発生したユニット９１に対応するオブジェクトを含んだこれらの情報を例外オブジェクト情報とする。拡縮処理部１２は、例外オブジェクト情報に基づいてエラーが発生したユニット９１の近傍をＰＬＣシステム２に指定された画面拡大率で表示部１０に拡大表示させる（ステップＳ４０３）。具体的には、図１６の部分領域９０を表示部１０の全画面に拡大表示させる。 First, the display unit 10 displays an overall view created by the user in FIG. 16 (step S401). In this state, an error occurs in a specific unit of the PLC system 2, for example, the unit 91 in FIG. 16 (step S402). The PLC system 2 sends error information including the unit 91 in which the error has occurred and a predetermined screen enlargement ratio to the exception processing unit 13. The exception processing unit 13 sets these pieces of information including the object corresponding to the unit 91 where the error has occurred as exception object information. The enlargement / reduction processing unit 12 enlarges and displays the vicinity of the unit 91 in which an error has occurred based on the exception object information on the display unit 10 at the screen enlargement ratio designated by the PLC system 2 (step S403). Specifically, the partial area 90 in FIG. 16 is enlarged and displayed on the entire screen of the display unit 10.
　このように、実施の形態５にかかるプログラマブル表示器１は、何らかの外部からのトリガ、例えば、ＰＬＣシステム２を構成するユニットのアラーム、ＰＬＣシステム２のメモリに保存されている外部のデバイス値の変更などに基づいて、表示部１０上の拡大箇所、画面拡大率等を外部から指定される。実施の形態５にかかるプログラマブル表示器１は、その指定内容に従って、ユーザが作成した全体図の一部である当該トリガの対象となる部分を、表示部１０に拡大して表示する。すなわち、実施の形態５にかかるプログラマブル表示器１は、画面拡大率や、表示座標などをプログラマブルコントローラなど外部の装置から指定可能にしておき、あらかじめ作成した画面の特定の領域を外部からの制御によって容易に表示させることが可能となる。 As described above, the programmable display device 1 according to the fifth embodiment includes some external trigger, for example, an alarm of a unit constituting the PLC system 2 and a change in an external device value stored in the memory of the PLC system 2. Based on the above, an enlargement location on the display unit 10, a screen enlargement ratio, and the like are designated from the outside. The programmable display device 1 according to the fifth embodiment enlarges and displays on the display unit 10 a portion that is a target of the trigger, which is a part of the overall diagram created by the user, in accordance with the specified content. In other words, the programmable display device 1 according to the fifth embodiment makes it possible to specify a screen enlargement ratio, display coordinates, and the like from an external device such as a programmable controller, and controls a specific area of the screen created in advance by external control. It can be easily displayed.
　実施の形態５にかかるプログラマブル表示器１によれば、ユーザが作成した画面上の外部から指定された領域へ、外部からの指示によって画面を移動して拡大することが可能となる。これにより、エラー発生時にユーザが確認したい場所を指定して画像拡大率を指定するなどの手間が省けるので、エラーが発生した際のトラブル処理の効率化が図れる。また、ユーザは、エラー発生用に拡大時の画面データなどを別途作成する必要がないため、ユーザの画面作成工数の削減を期待することができる。 According to the programmable display device 1 according to the fifth embodiment, it is possible to move and enlarge the screen by an instruction from the outside to an area designated from the outside on the screen created by the user. As a result, it is possible to save time and trouble such as designating a location to be confirmed by the user when an error occurs and designating an image enlargement ratio, thereby improving the efficiency of trouble processing when an error occurs. Further, since the user does not need to separately create screen data at the time of enlargement for the occurrence of an error, the user can expect to reduce the man-hours for screen creation.
　なお、実施の形態１から５においては、プログラマブル表示器１の機能ブロックとして、拡縮処理部１２、例外処理部１３などを用いて説明した。しかし、これらの機能はプログラマブル表示器１においてソフトウェアをＣＰＵが実行することなどにより実現される機能であり、必ずしもこのように区別されている必要はない。 In the first to fifth embodiments, description has been made using the enlargement / reduction processing unit 12, the exception processing unit 13, and the like as the functional blocks of the programmable display 1. However, these functions are functions realized by the CPU executing software in the programmable display 1 and need not be distinguished in this way.
　さらに、本願発明は上記実施の形態に限定されるものではなく、実施段階ではその要旨を逸脱しない範囲で種々に変形することが可能である。また、上記実施の形態には種々の段階の発明が含まれており、開示される複数の構成要件における適宜な組み合わせにより種々の発明が抽出されうる。例えば、実施の形態に示される全構成要件からいくつかの構成要件が削除されても、発明が解決しようとする課題の欄で述べた課題が解決でき、発明の効果の欄で述べられている効果が得られる場合には、この構成要件が削除された構成が発明として抽出されうる。更に、異なる実施の形態にわたる構成要素を適宜組み合わせてもよい。 Furthermore, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention in the implementation stage. Further, the above embodiments include inventions at various stages, and various inventions can be extracted by appropriately combining a plurality of disclosed constituent requirements. For example, even if some constituent requirements are deleted from all the constituent requirements shown in the embodiment, the problem described in the column of the problem to be solved by the invention can be solved, and is described in the column of the effect of the invention. When an effect is obtained, a configuration from which this configuration requirement is deleted can be extracted as an invention. Furthermore, the constituent elements over different embodiments may be appropriately combined.
　以上のように、本発明にかかるプログラマブル表示器およびプログラマブル表示器の表示方法は、ユーザの作業負担を低減した上で画面データを拡大または縮小することに有用であり、特に、ＰＬＣシステムのプログラマブル表示器などに適している。 As described above, the programmable display and the display method of the programmable display according to the present invention are useful for enlarging or reducing the screen data while reducing the work burden on the user, and in particular, the programmable display of the PLC system.
