Die Erfindung betrifft ein Software-Werkzeug zur Formulierung einer zu losenden Automatisierungsaufgabe gemäß dem Oberbegriff des Anspruchs 1. Darüber hinaus betrifft die Erfindung ein Programmiergerat mit einem derartigen Software- Werkzeug.The invention relates to a software tool for formulating an automation task to be solved according to the preamble of claim 1. Furthermore, the invention relates to a programming device with such a software tool.
Ein Software-Werkzeug gemäß dem Oberbegriff des Anspruchs 1 ist aus dem Siemens-Katalog ST 70, Ausgabe 2001, Kapitel 8 bekannt. Dort sind zur Formulierung einer zu losenden Auto- matisierungsaufgäbe auf einem Programmiergerat verschiedene Programmiersprachen, z. B. Programmiersprachen m Form von Contmuous Function Chart (CFC) oder Sequential Function Chart (SFC) , vorgesehen. Auf einer Anzeigeeinheit des Programmiergerätes ermöglichen diese Programmiersprachen eine Darstellung von Objekten, welche Teile einer zu steuernden technischen Anlage oder Teile eines zu steuernden Systems repräsentieren. Dabei sind mehrere Objekte aus einer mit vorlagenspezifischen Teilen, z. B. häufig vorkommende An- lagenteile, versehenen Vorlage erzeugbar, wobei gemäß dem so genannten Copy-/Modιfy-Konzept zunächst die Vorlage entsprechend der Anzahl der zu erstellenden Objekte kopiert wird. Anschließend wird jede Kopie mit objektspezifischen Teilen, d. h. mit entsprechenden den lokalen Erfordernissen angepassten Anlagenteilen, ergänzt, wodurch aus jeder modi- fizierten Kopie ein Objekt entsteht. Es kann nun vorkommen, dass aufgrund nachträglicher Fehlerbehebung oder Funktionserweiterung Änderungen m einer Vorlage vorgenommen werden müssen, was bedeutet, dass diese nderungen auch in den aus dieser Vorlage abgeleiteten Objekten einfließen müssen.A software tool according to the preamble of claim 1 is known from the Siemens catalog ST 70, edition 2001, chapter 8. There are different programming languages for the formulation of an automation task to be solved on a programming device. B. Programming languages m in the form of continuous function chart (CFC) or sequential function chart (SFC) provided. On a display unit of the programming device, these programming languages enable objects to be represented which represent parts of a technical system to be controlled or parts of a system to be controlled. Several objects are made from one with template-specific parts, e.g. B. frequently occurring system parts, provided template can be generated, according to the so-called copy / modify concept, the template is first copied according to the number of objects to be created. Then each copy with object-specific parts, i.e. H. with appropriate system components adapted to local requirements, which creates an object from every modified copy. It can now happen that changes have to be made in a template due to subsequent troubleshooting or functional expansion, which means that these changes must also be incorporated in the objects derived from this template.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Software-Werkzeug der eingangs genannten Art zu schaffen, welches eine nderung von vorlagenspezifischen Teilen m Objekten vereinfacht. Darüber hinaus ist ein Programmiergerat mit einem derartigen Software-Werkzeug anzugeben.The present invention has for its object to provide a software tool of the type mentioned, which simplifies a change of template-specific parts in objects. In addition, a programming device with such a software tool must be specified.
Diese Aufgabe wird im Hinblick auf das Software-Werkzeug durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Maßnahmen, im Hinblick auf das Programmiergerat mit den im Anspruch 2 angegebenen Maßnahmen gelost.This object is achieved with regard to the software tool by the measures specified in the characterizing part of claim 1, with regard to the programming device with the measures specified in claim 2.
Vorteilhaft ist, dass Vorlagen zentral erstellt und bearbeitet werden können, wobei die Modifikationen sich automatisch auf die Objekte auswirken, welche aus dieser Vorlage entstanden sind, ohne dass die nach lokalen Erfordernissen vorgenommenen Anpassungen an diesen Objekten verloren gehen.It is advantageous that templates can be created and edited centrally, the modifications automatically having an effect on the objects which have arisen from this template, without the adjustments to these objects which have been made according to local requirements being lost.
In einer Ausgestaltung der Erfindung gemäß den im Anspruch 2 angegebenen Maßnahmen wird jeder Vorlage bei ihrer Erstellung eine eindeutige und unverwechselbare Kennung, z. B. eine Kennung m Form eines so genannten Universal Unique Identifier (UUID) , zugeordnet. Ferner wird diese Kennung jedem Objekt, welches aus dieser Vorlage entstanden ist, zugeordnet, wodurch jedes Objekt eindeutig seiner Vorlage zugeordnet werden kann.

In Figur 1 ist mit Vol eine auf einer Anzeigeeinheit durch ein Software-Werkzeug erstell- und darstellbare Vorlage be- zeichnet, welche vorlagenspezifische Automatisierungsfunk¬ tionen VI, V2, V3 und V4 umfasst, von denen die Funktionen VI, V2 und V3 sowie V2 und V in Wirkverbindung stehen, was durch entsprechende Linien Lvl, Lv2 und Lv3 m der Darstellung ersichtlich ist. Es ist angenommen, dass die vorlagen- spezifischen Teile VI, V2, V3, Lvl und Lv2 nachträglich zentral modifizierbar sein sollen, was im vorliegenden Beispiel durch die schraffierte Darstellung der Automatisierungsfunktionen VI, V2 und V3 sowie durch die dick gezeichneten Linien Lvl und Lv2 angezeigt wird. Welche vorlagen- spezifischen Teile m der Vorlage Vol modifizierbar sein sollen, gibt ein Anwender z. B. durch eine Markierung dieser Teile mit einer Bedieneinheit m Form einer „Mausw vor. Eine derartige Markierung erkennt das Software-Werkzeug und ordnet diesen Teilen VI, V2, V3, Lvl und Lv2 erste Kennungen zu. Neben diesen ersten Kennungen erzeugt das Software-Werkzeug für die Vorlage Vol und für ede Kopie dieser Vorlage Vol eine zweite Kennung. Im vorliegenden Beispiel ist angenommen, dass die Vorlage Vol zweimal kopiert ist, weil entsprechend der zu losenden Automatisierungsaufgabe zwei Objekte Obl_01 und Ob2_01 zu erstellen sind, deren Gemeinsamkeit die vorlagenspezifischen Teile VI, V2, V3, Lvl und Lv2 der Vorlage Vol sind. Die vorlagenspezifischen Teile Lv2, V4 sind im Beispiel aus den Objekten Obl_01 und Ob2_01 entfernt, wobei das Objekt 0bl_01 neben den vorlagenspezifischen Teilen ob ekt- spezifische Automatisierungsfunktionen 01, 02, 03 sowie ob- jektspezifische Verbindungslinien Lol, Lo2, Lo3 und Lo4 aufweist; das Objekt Ob2_01 ist neben den vorlagenspezifischen Teilen mit den objektspezifischen Teilen 04, 05 sowie Lo5, Loβ und Lo7 versehen.In figure 1 is provided with Vol a on a display unit by a software tool erstell- and displayable template records loading, which template-specific automation radio ¬ functions VI, V2, V3 and V4, one of which functions VI, V2 and V3 and V2 and V are in operative connection, which can be seen from corresponding lines Lvl, Lv2 and Lv3 m in the illustration. It is assumed that the template-specific parts VI, V2, V3, Lvl and Lv2 should be able to be subsequently modified centrally, which is shown in the present example by the hatched representation of the automation functions VI, V2 and V3 and by the thick lines Lvl and Lv2 becomes. A user specifies which template-specific parts of the template Vol should be modifiable. B. by marking these parts with an operating unit m in the form of a “mouse w . The software tool recognizes such a marking and assigns first identifications to these parts VI, V2, V3, Lvl and Lv2. In addition to these first identifiers, the software tool creates a second identifier for the Vol template and for each copy of this Vol template. In the present example it is assumed that the template Vol has been copied twice because two objects Obl_01 and Ob2_01 have to be created according to the automation task to be solved, the common features of the template-specific parts VI, V2, V3, Lvl and Lv2 of template Vol. In the example, the template-specific parts Lv2, V4 have been removed from the objects Obl_01 and Ob2_01, whereby the object 0bl_01 has besides the template-specific parts whether ect-specific automation functions 01, 02, 03 as well as object-specific connection lines Lol, Lo2, Lo3 and Lo4; the object Ob2_01 is next to the template-specific Provide parts with object-specific parts 04, 05 as well as Lo5, Loβ and Lo7.
Es wird im Folgenden angenommen, dass die Vorlage Vol m der Art und Weise modifiziert wird, dass die Verbindung Lv2 geloscht wird und der Vorlage Vol eine neue vorlagenspezifische Automatisierungsfunktion V5 und neue Verbindungslinien Lv4 und Lv5 hinzugefugt werden, wodurch eine neue Vorlage Vo2 entsteht (Figur 2). Diese neuen vorlagenspezifischen Teile V5, Lv4 und Lv5 sind m der Darstellung auf der Anzeigeeinheit wieder besonders gekennzeichnet, z. B. ist die Automatisierungsfunktion V5 gestrichelt und die Verbindungslinien Lv4 und Lv5 dick dargestellt, was darauf hinweist, dass diese Teile wiederum zentral modifizierbar sind und das Software- Werkzeug in der beschriebenen Art und Weise für diese Teile jeweils eine erste Kennung zuordnet.It is assumed in the following that the template Vol m is modified in such a way that the connection Lv2 is deleted and the template Vol a new template-specific automation function V5 and new connecting lines Lv4 and Lv5 are added, whereby a new template Vo2 is created (FIG 2). These new template-specific parts V5, Lv4 and Lv5 are again specially marked in the display unit, e.g. For example, the automation function V5 is dashed and the connecting lines Lv4 and Lv5 are shown in thick lines, which indicates that these parts can in turn be modified centrally and the software tool assigns a first identifier for each of these parts in the manner described.
Aufgrund der zweiten Kennung, welche das Software-Werkzeug der Vorlage Vol und den Objekten Obl_01 und Ob2_01 zuordnete, erkennt das Software-Werkzeug, dass die Objekte Obl_01 und Ob2_01 vorlagenspezifische Teile der Vorlage Vol aufweisen.On the basis of the second identifier, which the software tool assigned to the template Vol and the objects Obl_01 and Ob2_01, the software tool recognizes that the objects Obl_01 and Ob2_01 have template-specific parts of the template Vol.
Ferner erkennt das Software-Werkzeug wegen der ersten Kennungen, die das Software-Werkzeug den zentral modifizierbaren vorlagenspezifischen Teilen zuordnete, welche vorlagenspezifischen Teile sich m der Vorlage Vo2 im Vergleich zu den Teilen m der Vorlage Vol geändert haben. Aufgrund dieser Kennungen fuhrt das Software-Werkzeug die vorlagenspezifischen Änderungen m den Objekten Obl_01 und Ob2_01 nach, die in der Vorlage Vol vorgenommen wurden, wodurch die modifizierten Objekte Obl_02 und Ob2_02 entstehen. Diese Objekte Obl_02 und Ob2_02 weisen also im vorliegenden Beispiel die vorlagenspezifischen Automatisierungsfunktionen VI, V2, V3 und V5 sowie die vorlagenspezifischen Verbindungen Lvl, Lv4 und Lv5 der Vorlage Vo2 auf, das bedeutet, im Vergleich zu der ursprünglichen Vorlage Vol wurden den modifizierten Ob- jekten Obl_01 und Ob2_01 die Automatisierungsfunktion V5 und die Verbindungen Lv4, Lv5 hinzugefugt, die Verbindung Lv2 wurde geloscht. Die objektspezifischen Teile der Objekte Obl_01 und Ob2_01, die Automatisierungsfunktionen 01, 02, 03 sowie die Verbindungen Lol, Lo2, Lo3 und die Automatisie¬ rungsfunktionen 04, 05, 06 sowie die Verbindungen Lo4, Lo5, Lo6 bleiben m den modifizierten Objekten Obl_02 und Ob2_02 erhalten.Furthermore, because of the first identifications that the software tool assigned to the centrally modifiable template-specific parts, the software tool recognizes which template-specific parts have changed in template Vo2 compared to the parts in template Vol. On the basis of these identifiers, the software tool tracks the template-specific changes in the Obl_01 and Ob2_01 objects that were made in the Vol template, which results in the modified Obl_02 and Ob2_02 objects. In the present example, these objects Obl_02 and Ob2_02 therefore have the template-specific automation functions VI, V2, V3 and V5 as well as the template-specific connections Lvl, Lv4 and Lv5 of the template Vo2, which means that compared to the original template Vol, the modified objects Obl_01 and Ob2_01 added the automation function V5 and the connections Lv4, Lv5, the connection Lv2 was deleted. The object-specific parts of the objects Obl_01 and Ob2_01, the automation functions 01, 02, 03 as well as the compounds Lol, Lo2, Lo3 and the automation ¬ approximation functions 04, 05, 06 as well as the connections remain Lo4, Lo5, m Lo6 the modified objects and Obl_02 Ob2_02 obtained.
Im Folgenden wird auf die Figuren 3 und 4 verwiesen, m welchen eine SFC-Darstellung von Automatisierungsfunktionen zur Losung einer Automatisierungsaufgabe gezeigt ist. In der beschriebenen Art und Weise sind in einer Vorlage Vo3 modifizierbare Automatisierungsfunktionen und modifizierbare Verbindungen Tv3 auf einer Anzeigeeinheit markierbar, wobei das Software-Werkzeug diesen Teilen Tv3 entsprechende erste Kennungen zuordnet. Ferner ordnet das Software-Werkzeug 0b- jekten 0b3, 0b4, die aus der Vorlage Vo3 hervorgehen, eine zweite Kennung zu. Aufgrund dieser Kennungen modifiziert das Software-Werkzeug die Objekte 0b3, 0b4 entsprechend den Modifikationen m der Vorlage Vo3. Im vorliegenden Beispiel ist die Vorlage Vo3 derart modifiziert, dass die Vorlage Vo3 durch Teile Tv4 ergänzt ist, wodurch eine modifizierte Vorlage Vo4 entsteht. Das Software-Werkzeug modifiziert die Objekte Ob3, 0b4 m der gleichen Art und Weise, wodurch modifizierte Objekte 0b5, 0b6 entstehen, welche die vorlagenspezifischen Teile Tv3, Tv4 der Vorlage Vo4 aufweisen, ohne dass die angepassten Teile 06, 07, 08 verloren gehen.In the following, reference is made to FIGS. 3 and 4, which show an SFC representation of automation functions for solving an automation task. In the manner described, modifiable automation functions and modifiable connections Tv3 can be marked on a display unit in a template Vo3, the software tool assigning corresponding first identifiers to these parts Tv3. Furthermore, the software tool 0b objects 0b3, 0b4, which result from the template Vo3, assigns a second identifier. On the basis of these identifiers, the software tool modifies objects 0b3, 0b4 in accordance with the modifications m of template Vo3. In the present example, the template Vo3 is modified such that the template Vo3 is supplemented by parts Tv4, whereby a modified template Vo4 is created. The software tool modifies the objects Ob3, 0b4 m in the same way, which results in modified objects 0b5, 0b6 which have the template-specific parts Tv3, Tv4 of the template Vo4 without the adapted parts 06, 07, 08 being lost.
Es wird im Folgenden auf Figur 5 verwiesen, m welcher eine durch das Software-Werkzeug erstellte, durch das Software- Werkzeug bearbeitbare und m einem Speicher eines Program- miergerates hinterlegbare Codierungstabeile dargestellt ist. In der Tabelle sind Vorlagen Vox, Voy eingetragen, von denen die Vorlage Vox mit einer zweiten Kennung Kl und die Vorlage Voy mit einer zweiten Kennung K2 versehen ist. Die Vorlage Vox weist vorlagenspezifische Teile V10, Vll, V12, Lvll und Lvl2 auf, denen jeweils eine erste Kennung zugeordnet ist. Im vorliegenden Beispiel ist dem vorlagenspezifischen Teil V10 eine Kennung Ka, dem Teil Vll eine Kennung Kb, ... zugeord- net. Aus der Tabelle ist weiterhin zu entnehmen, dass aus dieser Vorlage Vox zwei Objekte Oblx und Ob2x abgeleitet sind, da diesen Objekten Oblx, Ob2x ebenfalls die zweite Kennung Kl zugeordnet ist. Entsprechend sind Objekten Obly, Ob2y, Ob3y und Ob4y zweite Kennungen K2 zugeordnet, was darauf hinweist, dass diese aus einer die Kennung K2 aufweisenden Vorlage Voy abgeleitet wurden. Diese Vorlage Voy weist vorlagenspezifische Teile V20, V21 und Lv20 auf, denen das Software-Werkzeug erste Kennungen Kf, Kg und Kh zuord- nete. In the following, reference is made to FIG. 5, which shows a coding table created by the software tool, editable by the software tool, and m that can be stored in a memory of a programming device. Templates Vox, Voy are entered in the table, of which the template Vox is provided with a second identifier K1 and the template Voy is provided with a second identifier K2. The template Vox has template-specific parts V10, Vll, V12, Lvll and Lvl2, each of which is assigned a first identifier. In the present example, the template-specific part V10 is assigned an identifier Ka, the part Vll an identifier Kb, ... net. The table also shows that two objects Oblx and Ob2x are derived from this template Vox, since these objects Oblx, Ob2x are also assigned the second identifier Kl. Objects Obly, Ob2y, Ob3y and Ob4y are correspondingly assigned second identifiers K2, which indicates that these were derived from a template Voy having the identifier K2. This template Voy has template-specific parts V20, V21 and Lv20, to which the software tool assigned the first identifiers Kf, Kg and Kh.
