The method according to the invention will be described below with reference to the block diagram in FIG 1 with reference to the block diagram in FIG 2 which illustrates an embodiment of a method according to the method 1 created model M shows.

The inventive method according to 1 has the method steps S1-S3:

Process step S1:

A technical system A with at least two devices 1 - 5 will be provided. The at least two devices 1 - 5 are from a group of a manufacturing device 1 for producing a product, at least one control device 2 for controlling the manufacturing device 1 and at least one storage device 4 . 5 for storing an electronic documentation D1 of the manufacturing device 1 and / or the tax contraption 2 selected. The at least two selected devices lead 1 - 5 a respective function in dependence on at least one control parameter SP.

For the sake of clarity, without restriction of generality, in the 1 to 4 treated only a single control parameter SP. The respective function can, for example, in the manufacturing device 1 a manufacturing function, in the control device 2 a control function and the at least one storage device 4 . 5 be a memory function.

The technical system A preferably comprises a production device 1 with a storage unit, the control device 2 , a tax software 3 for loading into a storage unit of the manufacturing device 1 , a first storage device 4 for storing a first electronic documentation D1 of the manufacturing device 1 and a second storage device 5 for storing a second electronic documentation D2 of the control software 3 ,

Step S2:

A model M becomes for the at least two selected devices 1 - 5 created with a respective tag group TG for the respective control parameter SP. The respective tag group TG has in each case a tag T1-T5 for marking the corresponding control parameter SP in the respective selected device 1 - 5 ,

In this case, a tag T1-T5 is a specific reference to a date in the respective device 1 - 5 , Each day T1-T5 is a clear one and serves to mark a unique date.

According to the embodiment according to 2 becomes the model M for the manufacturing device 1 , the control device 2 , the control software 3 , the first electronic documentation D1 of the first storage device 4 and the second electronic documentation D2 of the second storage device 5 created a tag group TG for the control parameter SP.

According to the embodiment according to 2 with the five different devices 1 - 5 For example, the tag group TG for the control parameter SP has five different tags T1-T5 for marking the corresponding control parameter SP, namely a first tag T1 for marking the control parameter SP in the manufacturing device 1 , a second day T2 for marking the control parameter SP in the control device 2 a third day T3 for marking the control parameter SP in the control software 3 , a fourth day T4 for marking the control parameter SP in the first electronic documentation D1 and a fifth day T5 for marking the control parameter SP in the second electronic documentation D2.

Furthermore, preferably, a component K of the technical system A, which at least two devices 1 . 2 assigned to the technical system A, a unique component ID1 are assigned. According to the embodiment according to 2 component K has the manufacturing device 1 and the control device 2 and is identified by the unique component identifier ID1. In this case, the assignment of the respective component K to the respective component identifier ID1 is in particular a one-to-one illustration.

Of the Component K is at least a predetermined tag group TG or associated with a predetermined plurality of tag groups TG.

at a subsequent test the data consistency (according to method step S3), a respective component identifier ID1 can be selected and the data consistency of the associated tag group TG, which the selected component identification ID1 is assigned is checked.

The respective tag T1-T5 is formed by a tag tag Tag1, a device tag V1-V5 and the respective component tag ID1. The tag tag Tag1 is indicative of the control parameter SP, the device tag V1-V5 is indicative of the particular device 1 - 5 and the component identifier ID1 is indicative of the respective component K.

It shows 3 an example of a tag group TG for the control parameter SP. The tag group TG has according to the five devices 1 - 5 to 2 five different tags T1-T5, according to 1 the control parameter SP in the respective device 1 - 5 to mark.

For example, the component K has according to 2 a conveyor carpet plant 1 as a manufacturing device and a programmable logic controller (PLC) 2 as a control device. The component K is assigned the component ID1. The control parameter SP can, for example, the desired speed of the conveyor carpet plant 1 be. The in the programmable logic controller 2 Stored control parameters SP is marked by the day T2 (T2 = Tag1_V2_ID1).

In the first electronic documentation D1 of the manufacturing device 1 is the corresponding control parameter SP marked by the tag T1 (T1 = Tag1_V1_ID1).

Next is in the second electronic documentation D2 of the control software 3 the corresponding control parameter SP is marked by the tag T3 (T3 = Tag1_V5_ID1).

The tag group TG {Tag1_V1_ID1, Tag1_V2_ID1, Tag1_V3_ID1, Tag1_V4_ID1, Tag1_V5_ID1} represents the desired speed of the conveyor carpet installation 1 , The corresponding places in the devices 1 to 5 must therefore have the same numerical value.

Further, model M can create dependencies on data of the selected devices 1 - 5 be represented. Furthermore, the created model M can also include dependencies between individual or several tag groups TG.

Step S3:

The data consistency in each case of the control parameter SP marked by at least one part T1-T5 of the tag group TG is checked as a function of predetermined checking rules R in order to provide a test result. In particular, the data consistency of the control parameter SP marked by the respective tag group TG is checked. It may also be indicated, however, only the contents of the devices marked by a part of the tag group TG 1 to 5 to check for data consistency. This is possible in particular through the use of the component identifier ID1. This is useful, for example, if only a part of the technical system A can be tested, for example, if the other part is not available or if too much computation would be necessary.

In particular, the at least two selected devices perform 1 - 5 the respective function in dependence on a plurality of control parameters SP and the test rules R are created as a function of predetermined test priorities and / or predetermined test times for the plurality of control parameters SP.

Preferably, if a data inconsistency is established, at least one notification message is transmitted to at least one predetermined receiving device. Also, the notification message may be sent to a predetermined selection of receiving devices. Furthermore, in the case of a determined data inconsistency of control parameters of a respective tag group, at least one of the control parameters, which is marked by the tags belonging to the respective tag group, can be adapted in dependence on predetermined adaptation rules. For example, if the value of the control parameter SP becomes in the control software 3 changed, it will be at the next update to the programmable logic controller 2 played. However, if the value is changed in one of the two electronic documentations D1, D2, then it is automatically in the control software 3 adapted and thus with the next update to the programmable logic controller 2 played.

Consequently, preferably the respective electronic documentation D1, D2 has priority over the control software 3 , which in turn have priority over the programmable logic controller 2 Has.

These Adaptation rules are preferably dependent on predetermined adaptation priorities and / or adjustment times for the respective tag group TG or the majority of tag groups TG created.

Farther is preferably the testing the data consistency within the respective tag group TG depending from the predetermined test rules R and the created model M performed.

Preferably, the method steps S1 to S3 are after 1 preferably performed with a change of at least one predetermined control parameter SP.

alternative or additionally can the method steps S1 to S3 also after expiration of a predetermined Duration and / or occurrence of a predetermined event carried out become.

4 shows a schematic block diagram of an embodiment of an inventive arrangement 10 for checking the data consistency of a technical system A. In this case, the technical system A corresponds, for example, with reference to FIG 2 represented technical plant A.

The order 10 has a modeling tool 11 , a test agent 12 and a storage device 13 for storing test rules R.

The modeling agent 11 is suitable for a model M for the at least two selected devices 1 - 5 with a respective tag group TG for the respective control parameter SP, the respective tag group TG each having a tag T1-T5 for marking the corresponding tag group TG Control parameter SP in the respective selected device 1 - 5 having.

The test equipment 12 is furthermore suitable for the data consistency of the control parameter SP marked by at least one part of the tag group TG as a function of the predetermined checking rules R of the memory device 13 to provide a test result.

In this case, the arrangement 10 be used to check the consistency of all data according to the validation rules R. Due to the fact that a component K in the model M can be identified by an identifier or a component identifier ID1, it is also possible to check only a part of the technical system A for data consistency by selecting only the corresponding identifiers ID1.

in the Below is an embodiment of the Invention with the sections modeling, creation of rules and review described:

modeling

For example, the in 2 illustrated manufacturing device 1 as a conveyor carpet plant and the control device 2 can be considered a programmable logic controller 2 (PLC) be designed. A control parameter SP can be, for example, the conveying speed, for example of 2 m / s.

In the first electronic documentation D1, which this conveyor carpet plant 1 describes the following sentence: "The conveyor carpet installation must reach a nominal speed of <Tag1_V1_ID1> 2 m / s> Tag1_V1_ID1 <in this operating mode. The value of the velocity can therefore be marked, for example in XML-like notation, by the tag1_V1_ID1.

Furthermore, in the second electronic documentation D2, which contains the control software 3 describes a corresponding sentence: "The variable <Tag1_V3_ID1> SP <Tag1_V3_ID1> represents the control value for the speed of the conveyor carpet plant". The value of the velocity is marked here in XML similar notation by the tag Tag1_V3_ID1.

In the control software 3 the control parameter SP can be marked by the tag Tag1_V3_ID1.

In the PLC 2 is the control parameter SP to the speed of the conveyor carpet plant 1 marked by day tag1_V2_ID1.

Furthermore, the model M can be created as a component-based model M of the technical system A, in which components K are designated and referenced with a respective identifier ID1. This identifier ID1 can be assigned a list of attributes, namely all tags that relate to this particular component K. For example, this list of attributes is in 3 shown.

Creation of the rules

• – Alle Tags T1–T5 der Tag-Gruppe TG müssen dieselbe Geschwindigkeit darstellen, wobei die Konvertierung zwischen den Einheiten km/h und m/s zu berücksichtigen ist.
• – Der dritte Tag T3 zur Markierung des Steuerungsparameters SP der Steuer-Software 3 bestimmt beim Erstellen der Firmware für die SPS den Wert des Tags Tag1_V2_ID1. Falls sich diese beiden Werte danach unterscheiden sollten, wird die Betriebsleitung durch eine Benachrichtigungsnachricht, wie eine E-mail, informiert.
• – Falls sich die Werte von Tag1_V3_ID1 und Tag1_V5_ID1 unterscheiden, bestimmt die zweite elektronische Dokumentation D2 der Steuer-Software 3 den zu implementierenden Wert. Also wird der Wert von Tag1_V3_ID1 mit dem Wert von Tag1_V5_ID1 angepasst und es kann eine Warnung an die Entwicklungsleitung geschickt werden.
• – Falls sich die Werte von Tag1_V4_ID1 in der ersten elektronischen Dokumentation D1 der Herstellungsvorrichtung 1 und von Tag1_V5_ID1 in der zweiten elektronischen Dokumentation D2 der Steuer-Software 3 unterscheiden, wird eine E-mail mit hoher Priorität an die Entwicklungsleitung und an die Betriebsleitung gesendet, damit der Konflikt durch einen Entscheidungsträger gelöst werden kann.

All tags T1-T5, the control parameter SP of the speed of the conveyor carpet plant 1 TG = {Tag1_V1_ID1, Tag1_V2_ID1, Tag1_V3_ID1, Tag1_V4_ID1, Tag1_V5_ID1} are summarized in a tag group. The checking rules R can include the following rules:

• - All tags T1-T5 of the tag group TG must represent the same speed, taking into account the conversion between the units km / h and m / s.
• The third day T3 for marking the control parameter SP of the control software 3 When creating the firmware for the PLC, determines the value of tag Tag1_V2_ID1. If these two values differ, the management is informed by a notification message, such as an e-mail.
• - If the values of Tag1_V3_ID1 and Tag1_V5_ID1 differ, the second electronic documentation D2 determines the control software 3 the value to be implemented. So the value of Tag1_V3_ID1 is adjusted with the value of Tag1_V5_ID1 and a warning can be sent to the development manager.
• If the values of Tag1_V4_ID1 are in the first electronic documentation D1 of the manufacturing device 1 and Tag1_V5_ID1 in the second electronic documentation D2 of the control software 3 A high priority e-mail is sent to the development management and management to resolve the conflict through a decision maker.

Verification

• a) Case 1: Change of the control parameter at the PLC An employee of the technical plant A comes to the opinion that the technical plant A works much better in his view, if the conveyor carpet 1 a little faster, for example, 9 km / h, ran. By means of an operator panel, it changes the value for the control parameter SP at the PLC 2. Then the technical system runs at 9 km / h. At the next inspection of the technical installation A it is determined that this 9 km / h does not correspond to the value of the control parameter SP in the control software 3 correspond. An e-mail will then be sent to the management. The management can determine that this change causes a congestion at another location of the technical installation A and decides to return the value to the original 7.2 km / h.
• b) Case 2: Change of the control software For example, an employee of the technical system A asked the software team for the next software update the speed of the conveyor carpet installation 1 to 9 km / h, since this value is optimized from his point of view. The software developers thus change the variable corresponding to the control parameter SP in the control software 3 so that this corresponds to 9 km / h = 2.5 m / s. At the next check of the technical equipment A it is determined that this variable of the control parameter SP does not correspond to the value in the second electronic documentation D2 of the control software 3 equivalent. The value in the control software 3 is then automatically reset to the value of 2 m / s and a warning message is sent to the development management. Thus, the development manager has the opportunity to discuss with the software team and the management, if 2 m / s is the right value.
• c) Case 3: Change in the second electronic documentation An employee of the technical system A has not noticed the above and now asks the development team of the control software 3 , the second electronic documentation D2 of the control software 3 adapt. At the next inspection of technical plant A, it is determined that the corresponding value in the first electronic documentation D1 of the manufacturing device 1 does not correspond to the value in the second electronic documentation D2. An e-mail with high priority is then sent to the development management and management. These can then decide together about the value for the control parameter SP.

Even though the present invention described above with reference to the preferred embodiments it is not limited to that, but in many ways and modifiable.
