Configuration of an operating procedure of a process and / or manufacturing plant

The invention relates to an apparatus and a method for configuring an operating sequence of a process and / or production plant, or briefly plant. Such a plant may comprise one or more plant components, wherein a plant component may be for example a conveyor belt, a CNC machine or a bottling machine.

The configuration is achieved in this case by means of a control program which can be executed by at least one programmable Stellein ^¬ standardize the system, eg a microcontroller of a plant component. For this purpose the STEU ^¬ erprogramm is provided as respective binary code for the at least one actuating unit. When executing the binary code by all actuators then results in the desired operation in the system. But binary code is not a ^¬ Zige variant of a control program. It is also possible to generate a control program in an interpreter language that can be executed directly. This is common, for example, with robots and CNC machines. In general, a control program is a list of control commands and variables, whereby the list can also be divided into several files.

To speed up the development process for configuring the operating procedure, such a control program is often no longer written by the programmer manually.

Rather, so-called templates or templates are used, which define an operating behavior of individual plant components, ie define the part of the operating procedure that relates to this plant component. However, a template does not have to be assigned one to one to a plant component. It can also be a single algorithm within a plant component or an entire group of several plant communities. components represent, since the mechanical Komponentenbil ^¬ dung is other than the closed-loop control component formation in a plant, and the latter is represented generally by the templates. It is important, above all, that the operating behavior as a whole is defined by a set of templates. No statement is made about the involved hardware. For example, a template can also be an algorithm for a specific subtask (especially in the CNC area). A template generally defines a specific process section.

For this purpose, a template may include, for example, hard-coded code fragments for individual functional sections of the control program. By adjusting individual parameter values the template can also be adapted as required, so that the associated Pro ^¬ zessabschnitt behave in the desired manner. So Beispielswei ^¬ se may be provided, for example for controlling ei ^¬ nes conveyor belt and are determined by adjusting ei ^¬ nes parameter, the conveying speed a template. Such templates are usually presented graphically to a user interface, such as a workstation computer, to a user. The user can then associate the individual templates on the operator panel so that the linked templates represent the structure of those assets whose operation is to be configured.

The finished linked templates / templates then form a total flowchart for the operating procedure. A Codegenera ^¬ tor can then generate the control program automatically from such a schedule. For this form also known as Engineering of configuring, often a ^so-¬-called engineering tool is provided. Such a tool is, for example, the product "Comos" of the company Siemens AG In such an engineering tool, the templates are provided by so-called library blocks, which are linked to the above-mentioned control unit to a flowchart, which is part of a so-called project for plant ^¬ engineering From the schedule, a tax gram for one or several different Zielsys ^¬ systems, ie plants with similar structure, are generated.

However, the flowchart is only a partial aspect of the project for plant engineering. It is also possible to express the HMI (operator interface), superordinate control systems (MES), communication ^parameters , electrical plans, documentation and other elements by means of the templates - the flowchart or the data used for the code generation are only part of it. This is important insofar as that characterized stand interpreting ^¬ Lich complex dependencies within the project ^¬ ent. It is important at this point that the project has a specific structure as a whole, which represents the to automatic ^¬ sierende attachment in multiple facets and is not solely focused to the actual code generation, so the generation of a specific control program.

A complete automated generation of Steuerpro ^¬ program is usually not realistic. Often manual adjustments of the automatically generated control program by the commissioning engineer of a plant are required. Depending on the system, the scope of these changes may range from simple additions in the control program to a complete restructuring of the program blocks, ie the text of the control program, or the call structure of individual program functions if, for example, other device types have been installed in a plant at short notice than this was originally planned. One problem with the manual change of a control program for adapting to the actual structural properties of the system to be automated now is that when a new generation of the control program using a Codege ^¬ nerators the manual changes are no longer included in this newly generated control program. Therefore, this step of manually adjusting the control program usually needs to be repeated each time. Similar problems occur in the configuration of an operation ^¬ process on a CNC machine. Even such a CNC machine is often not directly programmed, but from a so-called. CAD-CAM-CNC chain results on the basis of design ^¬ specifications of the CAD (Computer Aided Design) a sequence of manufacturing steps in a CAM system (CAM - Computer Aided Manufacturing). From these manufacturing steps, the control program for the CNC control units is then generated. Such a control program is based on a prototype for the individual CNC machines. Depending on the age and wear condition of the CNC machines or on the type of workpieces to be processed with them, the control program may have to be adapted by the machine operator to the concrete structural properties of the CNC machine. Again, there is the problem that when re-creating the control program, for example, to incorporate changes, then again the manual adjustments by the machine operator are needed.

From the prior art, round-trip engineering is known as an approach to solving this problem

(http://en.wikipedia.org/wiki/Round-trip_engineering). In this approach, the manual changes are transferred back to the source system, ie the schedule or templates are changed again. Will happen to the flow chart a new control program generated, this includes the nö ^¬ term changes already. In order to allow the changes in the flow chart, a code comparison between the control program which has been generated by the code generator automatically current, and the adjusted control program formed therefrom by the manual Variegated ^¬ stanchions is performed. The case identified differences are then in the source ^¬ system, ie the schedule or the documents transmitted. However, this approach only works well if only prefabricated hard-coded code fragments have to be changed, ie if the automatically generated code blocks and the subsequently manually added code blocks can be neatly separated. But this is rarely the case. Rather ei ^¬ ne wider manual change is often necessary after the creation of a control program of a flowchart. In many cases in the control program, parameters and the structure of the control program are influenced in order to achieve optimal networking between the various plant components and increased flexibility in setting control values. Manual changes that affect such structurally critical parts of the control program or even cause a change in the data structure of the control program itself, can not be automatically incorporated into the flowchart without damaging the dependencies within the project. The automatic ^¬ tisierte processing of a flowchart for generating a control program is attached to fixed rules, which are usually too rigid. In a CAD-CAM-CNC chain, a change in the area of Maschinenkinema ^¬ tik and machine geometry is to the automatic ^¬ table generated control program by the manual changes often (for example, cutter angle of attack), as well of the tool geometry, in particular made of the manufacturing strategy. A typical example of a manual Anpas ^¬ solution by a machine operator is the addition of additional cutting planes, if, for example, in a Gußrohteil the blank geometry deviates from the planned geometry in the CAM system. A return of this adaptation in the CAM system is usually complex and must be performed by an expert ma ^¬ nually. This is where the round-trip engineering fails.

The invention has for its object to promote automation in the configuration of an operation of a process and / or manufacturing plant.

The object is achieved by a device according to claim 1, a method according to claim 8 and a computer program product according to claim 13. Advantageous developments of the invention are given by the dependent claims. According to the invention, the code generation process for generating the control program from a flowchart is supplemented by an editing script, that is to say a sequence of instructions which can be executed by an editing device, for example a processor. After generating a preliminary control program from a flowchart, which was created in the described manner from interlinked templates, this preliminary control program is adapted by the editing unit to the structural characteristics of the plant such that corresponding manual changes are no longer necessary. As a result, by executing the editing script by means of the editing unit from the provisional control program, an adapted control program. The adapted control program can then be written in the known manner, for example in an interpreter language, eg for a CNC machine, or converted into a binary code for the at least one control unit, eg for a PLC (memory programmable controller). The latter requires an additional compilation step of a compiler unit, which is designed to convert an adapted control program into a binary code for the at least one control unit and to ^{output it} . The Editierskript comprises at least one instruction for ANPAS ^¬ sen the provisional control program. This is in particular textual changes to the provisional program that can not be accommodated in the schedule itself, because it would require a change in the schedule ER that could be reali ^¬ Siert only with high development costs.

The inventive method thus has the advantage that the control programs can be adapted in an automated form to the structural characteristics of a particular target system, ie, for example, the exact structure, the state of wear of system components or the manufacturing ^¬ tolerances of workpieces. The same advantage can also be realized with the device according to the invention, which makes it possible to carry out the erfindungsge ^¬ MAESSEN method. The device is thus provided for configuring an operating sequence of a process and / or production plant. It comprises the described loading ^¬ diene unit, which is adapted to a user before ^¬ lay is defi ^¬ defined through which a part of the operation, and to provide these templates in accordance with the input as possible of the user to link to a schedule. A code generator unit or a short code generator is adapted to generate a preliminary Steuerpro ^¬ program for at least one programmable actuator to the ^¬ base of this flowchart. To generate from this preliminary control program then an adapted control program, the

The device comprises a memory unit which is designed to store an edit script, which in the manner described comprises at least one instruction for adapting the preliminary control program to specific, structural properties of the system. With this memory unit and the code generator unit ^¬ an editing unit is coupled, which is designed to generate from the provisional control program by executing the at least one instruction of the Editierskripts the customized control program and pass it on to the system training. Preferably, one or more editing scripts are already stored in the memory unit.

The invention is suitable for the configuration of operations of different plants. Accordingly, the Co is preferred to degeneratoreinheit designed by the prior ^¬ provisional control program at least one of the following

To control actuators: A programmable Regge ^¬ ment, a programmable logic controller, a controller of a CNC machine. As already stated, the control program can consist of subroutines, each of which is provided for a corresponding control unit of the system, for example a subprogram for a control of a conveyor belt and a subprogram for the control of a conveyor belt. nes filling machine to which the conveyor belt promotes empty bottles.

Since in the invention the adaptation of the control program is not indirectly via a change of the schedule, but di ^¬ rectly by changing the automatically generated preliminary control program, which is in textual form, the changes may be relatively simple instructions. An embodiment of the invention provides that the editing unit is designed to carry out simple, pure text substitutions in order to generate the adapted control program. In particular, at least one parameter contained in the preliminary control program is replaced by another value specified by the editing script. As a result, the operating behavior of the system can be adapted to, for example, a state of wear of a system component in an advantageous manner. All ^¬ common is provided in this embodiment that the editing unit is adapted to replace for generating the angepass- th control program a text area of the preliminary control program by another text region that is dictated by the Editierskript.

The use of an editing script is generally not limited to pure textual substitutions, but can also be made possible for hierarchically structured data structures, such as data trees and other acyclic, directed graphs. For this purpose, one embodiment of the invention is that the editing means is adapted to convert for generating the adjusted control program, a data structure of the preliminary control program by shifting program preparation ^¬ chen in a target structure, which is predetermined by the Editierskript. A particularly preferred embodiment of the invention ^shown SEN device provides to generate a Editierskript or more Editierskripte in an automated fashion by the apparatus itself and save it in the storage unit. To this end, then in the device, a script generation unit is provided which is adapted to compare the control program to preliminary ^¬ ge with a previously manually adjusted by an operator control program of the plant. A Editierskript is based on this recognized differences between these two control programs generated in the manner that, for carrying out the Editierskripts textually by the editing, the matched Steuerpro ^¬ program produced thereby with the manually adjusted control program, but at least functionally matches. To realize this scripter ^¬ generating unit, can be applied to different known techniques are resorted from the prior art. To obtain instructions for pure text substitutions, for example, so-called diff tools can be used. Such tools allow the recognition of syntax substitutions, ie changes of text areas independent of their semantics. For example, it is recognized by such a tool whether, for example, a text area having the value "100" was made by the operator from a text area having a value "50" in the provisional control program.

In order to recognize a change in the data structure per se, it is possible to fall back on generic approaches existing in the specialist literature for the creation of an editing script. Such approaches to automatically generate edit scripts have been described, inter alia, by Chawathe et al. described in the science ^¬ official publication "Change detection in hierarchically structured information."

By storing of such automated generated edit ^¬ scripts in said storage unit, the editing ^¬ then script together with the flow chart stored, so that from then on after re-generation of a preliminary control program by executing the Editierskripts the control program code previously generated by manually adjusting now au ^¬ automatically arises. So this approach provides in vorteilhaf ^¬ ter, the opportunity to run in the target system manu- All changes, that is to say in the system set up by an operator, must be archived together with the schedule in such a way that no manual changes are lost when the code is regenerated. In contrast to the prior art, however, there is no time-consuming integration of the changes in the flowchart itself, so that planning steps can still be carried out very flexibly at the level of the flowchart. The Editierskripte automatically generated in accordance with one at ^¬ whose aspect of the invention further comprises a good help Stel ^¬ lung to detect the points at which manual changes, for example, to changeovers particularly frequently carried out in the control program and the points at which not. This knowledge can then be used advantageously for subsequent projects with a similar task, ie the planning of an operating sequence of another system to structure the templates for forming the new schedule so that already in the provisional control program generated from the otherwise necessary, frequently occurring Changes are already included in the schedule itself. For this purpose, an embodiment of the invention provides that an analysis unit is provided in the device, which is designed to compare two or more editing scripts of the type mentioned. The comparison then determines how often certain changes have been made to the adjustment. If the frequency of a certain change is greater than a predetermined threshold value, this change is then signaled, ie, for example, displayed or made identifiable in another form by an operator. Instead of comparing two or more ^¬ rer Editierskripte two or more can also be provided, chen be compared with that of each control program by an operator manually adjusted control programs of the system that was used by the operator in each case as a template. So takes in the course of the operation of the system in the context of restructuring of the plant, as they may be necessary for production changes, for example, an operator for the adjustment of the control program used repeatedly the same manual changes to the control program, this means that the relatively complex adjustment process for the flowchart itself or its components, ie the templates, seems justified. Since only the most frequent changes are taken as a basis, the flowchart or its templates is changed only in an advantageous manner, if that is worthwhile.

An advantageous development of the device provides in this case that the analysis device is designed to ^{¬ on the} basis of the frequently made changes to change at least one of the templates automatically, so adapt to the example of the described Comos system a library block.

In another development of the invention several different Editierskripte be bereitge ^¬ represents, each of which is adapted to adjust the preliminary control program of specific structural characteristics of another plant for the schedule. ^¬ be selected and in response to a user selection of one of the Editierskripte by the editing means for generating a customized control program for the associated plant is then used as a basis of the preliminary control program. Thus, a single schedule for plant engineering several plants can be used.

The above-mentioned process of the invention comprises optionally further developments just ^¬ include the features as be ^¬ already described in connection with the described developments of the device according to the invention. For this reason, the corresponding developments of the method according to the invention are not again erläu ^¬ tert. Of course, the invention can also be combined with a known round-trip engineering method.

Finally, the invention also includes a computer program product which makes it possible to carry out an embodiment of the method according to the invention on a workstation computer. For this purpose, the computer program product has a corresponding program code which is stored on at least one storage medium and is designed to perform the corresponding method when the program code is executed by a workstation computer.

In the following, the invention is explained once again with reference to concrete exemplary embodiments. For this purpose, the single FIGURE (FIG) shows an embodiment of the device according to the invention. The device 10 shown can be provided, for example, as an engineering tool, for example as a further development of the known Comos system. The device 10 may for example be reali ^¬ Siert as a personal computer or a computer system from a plurality of computers. From the apparatus 10 a control unit 12, a code generator unit 14, an editing unit 16 and a storage unit 18, and a Skripterzeugungs- and Analy ^¬ seeinheit, or shortly analysis unit 20 bezeigt. The operating unit 12 comprises a database 22 with library ^components 22 '. The control unit 12 further comprises a gra ^¬ fish man-machine interface or short-interface 24, by means of which (not shown) the operator of the device 10 is a flowchart 26 rocks from the Bibliotheksbau- 22 'design. The flowchart 26 recreates the structure of the plant 40.

The units 14, 16, 24, 36 may for example be provided as pro ^¬ program module. The storage unit 18 and the database 22 may be provided, for example, by one or several ^¬ re files that are stored for example in a hard disk. By means of the device 10, control programs 28, 30, 32, 34 can be generated. The control programs 28, 30, 32, 34 can be, for example, programs in the programming language STEP7 AWL or according to the programming standard IEC

Act 61131-3. A compiler unit 36 of the device 10 is designed to translate a respective control program 28, 30, 32 into a binary code 38, which either directly or indirectly, for example by means of a storage medium, to a process and / or manufacturing plant to be automated or short Appendix 40 can be transmitted, where the binary code 38 is divided into several actuators 42 and stored there in program memories. The actuators 42 control in the system 40 system components, of which, for example, a bottle cleaner 44, a bottle filling 46 and a bottle cleaning 44 and the bottle filling 46 connecting conveyor belt 48 are shown. By adjusting ^¬ units 42 each one of these system components 44, 46, 48 is controlled or regulated in response to the binary units stored in the 42 binary code, so that this results in a total determined by the binary code 38 operation in the system 40.

By means of the device 10, the operator does not have to program the control programs 28, 30, 32, 34 himself. The control programs are generated by the code generator unit 14 from the schedule 26. The individual library blocks 22 'of the control plan 26 determine individual program areas of the control program 28, 30, 32, 34. As the program areas defined by the individual library building blocks 22 'are linked to one another, the operator defines them by corresponding links 50 in the flowchart 26. The operator can also set parameters within the individual library blocks 22 '. However, a control program 28, 30, 32, 34 generated on the basis of the flowchart 26 by the code generator unit 14 must, as a rule, still be changed by the operator, so that the control program 28, 30, 32, 34 adhere to the specific, structural characteristics of the system 40 adjusted in order to For example, to take into account a reduced Fördergeschwin ^¬ speed of the conveyor belt 48 by wear. For this purpose, the device 10 may have a round-trip engineering functionality RTE. If, for example, the control program 28 is generated on the basis of the flowchart 26 by means of the code generator unit 40, this is a provisional control program with the program content PI. The operator can then change in a simple embodiment, individual Pa ^¬ rameterwerte VAL in the control program 28, and receives at the adjusted so control program 30 with the program content PI '. By means of the round-trip engineering RTE, a comparison can be made between the control programs 28, 30 and thus the change in the parameter values VAL can be recognized. In this ideal case, if the structural identity of the two control programs 28, 30 is not changed because only individual parameter values VAL have been changed, the manual changes can be simply transferred to the source system with the normal methods of the round-trip engineering RTE, ie Schedule 26 or even in the library blocks 22 '. Is then again a control program of the flowchart 26 by means of the generator unit 14, he attests ^¬, one obtains directly the control program 30, which is identical with the manually modified ^¬ table control program 28th However, in case the manual changes are structurally critical, the changes can not be easily integrated into the source system. The classic round-trip engineering RTE will fail here, or it will require a lot of manual overhead to adjust the source system accordingly. As an example, as the operator is still going on after changing the parameter values VAL and the structure STRUCT of Steuerpro ^¬ program 30 shown in FIG changed, so for example, program areas, so individual passages in the control program shifts or changes of text with function calls. As a result, the operator receives the control program 32. In order to be able to map this new structure of the control program 32 in the flowchart 26, the programmer would have to use the library Modules 22 'to be changed, for example, one of the Bib ^¬ liotheksbausteine 22' split into two blocks or create a new library block. This would mean that the operator must commission a programmer for this purpose. However, this is not necessary with the device 10.

The analysis unit 20 of the device 10 compares the STEU ^¬ erprogramm 28 and the control program 32 and generates therefrom instructions for the editing unit 16, they animal script at a EDI summarizes 52nd The edit script 52 is stored in the storage unit 18 by the analysis unit 20. The FIG shows that further editing scripts 54 can also be stored in the memory unit 18. For example, if the operator has the texture program 28 for

Operation of another (not shown here) system also adapted, then the other editing script 54 may have been formed by the analysis unit 20 therefrom.

Based on the editing script 52, the operator, based on the schedule 26, can have the control program 32 automatically generated by the apparatus 10 as a customized control program 34. For this purpose is generated from the flow chart 26, by the code generator unit 14 as a provisional ^¬ Figes control program 56 of the program content Tl, which is transmitted by the code generator unit 14 to the editing unit sixteenth The editing unit 16 changes the code ^content PI on the basis of the instructions from the editing script 52. In other words, the editing unit 16 executes the editing script 52. The Editierskript 52 includes solutions, by which from the program content PI parameter values ^¬ VAL changed and also the structure STRUCT changing the Anwei-. The editing unit 16 outputs, as the changed program content, the program content P2 as the control program 34, which is now adapted directly to the properties of the system 40 without any intervention on the part of the operator. The adapted

Control program 34 can now be translated by means of the compiler unit 16 in the binary code 38 and transmitted to the actuators 42 of the system 40. The possible uses of a device designed according to the invention are versatile. For this purpose, further examples are given below.

Comparisons to back the figure: PI, PI ^λ and P2 can also be provided for three different investment projects, all still in use after commissioning and maintenance ^¬ to, with PI and PI ^λ divorce must comply only with parameter values, ie the associated systems have no structural differences even after commissioning. P2, on the other hand, was changed during commissioning in such a way that structural differences exist. It is thus clear that the amendments ^¬ implications for future generation of P2 can be saved only by the script editing approach, since when integrated into the Comos Project would destroy the generational chemistry PI and PI ^λ ect otherwise.

In a first additional example, a plant manufacturer for the transport of bottles for controlling switches for cost reasons in many places, for example, timers, to save sensor technology in this way. Thus, for example, at the entrance of a strip section where bottles of type A or type B can arrive, the bottle type is registered once by sensor and the following points are activated by timer on the basis of the known strip speed so that the bottles according to their type in different On ^¬ parts of the parts to be forwarded. Since the bottles are introduced relatively close to each other in the band section, the timers must be precise enough to avoid missing turnouts.

The values of the timers are calculated from the lengths of the band sections and the band speeds known in the source system, and a data block is entered for the code generation of the control program for the system. During commissioning, however, the values of the timers often have to be adapted more precisely. Furthermore, it can - both in the case of As well as in later changeover phases - changes in the geometry of the system can occur, so that, for example, individual conveyor belts are shortened or points are shifted, which in turn has an effect on the timers.

In classic round-trip engineering, when the data is read back from the modified data block, it is determined that there is a deviation. Since the timer values are not hard-coded in the source system, but is calculated from the lengths and speeds of the individual strip sections, lack the means to accommodate these modified Ti ^¬ merdaten in the source system directly. Overwriting the calculated timer values in the source system with the real values entered during commissioning in the target system of the system would destroy the dependency on the calculation, which would, for example, lead to major problems when carrying out simulations of conversions.

By using an edit script 52, 54, one can simply store the new timer data from the target system so that the corresponding data block in the preliminary control program 56 is written with the correct data during code generation without the dependencies in the object structure of the source project, ie of the schedule 26, to be destroyed.

If, at a later point in time, in order to increase the efficiency of the system development, for example, the system designer wishes to create new templates or library modules 22 ', he can analyze the history of the editing scripts 52, 54 from previously commissioned systems. Here, he notices that the timer values have been changed several times for almost all investments during the plant life cycle, these amendments ^¬ conclusions could only be very costly entered into the object structure of the source system but if this was done at all. Based on these data it is easy to recognize for the Anla ^¬ genbauer that this action is needed and the library blocks 22 'adjusted accordingly should be. For this purpose, for example, corresponding offset parameters can already be introduced for the timer values in the source system, into which hard-coded deviations from the calculated value can then be entered.

In another example, when creating an NC program, the NC programmer works with theoretical values. When planning a cutting layout of a blank, the manufacturing geometry and the assumed blank geometry are used. Due to tolerances or quality problems of the blanks, there may be significant deviations from the desired geometry. As a result, the machine operator must adapt the NC program based on the theoretical geometry. For this he changes e.g. the cutting layout or inserts additional cuts.

At the latest, the insertion of additional machining operations by the machine operator leads to a structural change of the control program for the CNC machine. This change can then no longer be traced back to the flowchart. As a flowchart, a CAM program is to be understood in connection with CNC machines. By using edit scripts 52, 54, however, additional processing besides the actual source system can be stored in the memory unit 18.

By evaluating all Editierskripte 52, 54, incurred in the course of operation of the CNC machine based under ^¬ schiedlicher schedules, later even back conclusions about the production process can be drawn. With ent ^¬ speaking evaluations eg weaknesses or problems can be detected, which have arisen due to tolerances or quality problems. If, for example, the feed rates are always reduced for a particular fixture, this may indicate, for example, a lack of rigidity. In the above example, an evaluation of editing scripts for all components of a series can for example show the problems with the quality of the stock. In a third example, an NC programming again assumes ideal conditions. However, these are often not available in production, as already described. In many cases, with changes in the NC

Program reacts to the wear of the working equipment. Thus, e.g. Target coordinates changed to compensate for the wear of machine guides. Another commonly used method is zero offset to compensate for errors in the fixture system.

By an evaluation of several edit scripts 52, 54, which result from a comparison of the provisional, automatically generated CNC control programs with the adapted CNC machining systems formed therefrom by the machine operator.

Control programs, such tendencies can be detected early on, before the components completely wear ^¬ Shen. Accordingly, then further damage is avoided and prevents deterioration of productivity.

Overall, is shown by the examples, as a normal generating process control programs to a second stage weitert will he ^¬ to make changes to the preliminary textual, generated in the first stage control program. These changes are based on textual editing scripts 52, 54, which performs an editing unit on the basis of provisional tax ^¬ program, which then causes the manual changes are taken into account, which could be incorporated into the project structure of the source system easily.

A Editierskript for this second generation stage since ^¬ with updated automatically by means of the analysis unit 20 so that, a complete acquisition of manual changes which are performed in the target system of the plant 40 be made without manual intervention on the part of the source system. This allows easy and fast archiving of manual changes, so that the problem of duplicate Data storage, in which both source and destination control programs are included, is avoided.

An important further development of this approach is to analyze the editing scripts that occur during the life cycle of an engineering project, in order to derive concrete information about where in the control program particular manual changes are made. This information can be used in order during generation of similar projects development templates, templates or Biblio ^¬ theksbausteine 22 'and optimize the object structure in the form of the flow ^¬ planes 26 so that manual integration implemented in the target system the plant 40 Changes in the target system is as easy as possible. This significantly reduces the time required to maintain an engineering project.

In addition, systematic errors in the design can be derived from the analysis of the editing scripts. This is particularly useful for CAD-CAM CNC chains, as there, for example, frequent changes to the control programs can indicate an above-average wear or a faulty configuration.

3. Apparatus (10) according to any one of the preceding claims, wherein the editing unit (16) is adapted to substitute a text area of the preliminary control program (56) with another text area (VAL) to create the customized control program (34); specified by the edit script (52, 54).

4. Device (10) according to any preceding claim, wherein the editing unit (16) is adapted to Erzeu ^¬ gene of the adapted control program (34) a data structure of the preliminary control program (56) by shifting program areas in a target structure (STRUCT) specified by the edit script (52, 54).

5. Device (10) according to one of the preceding claims, wherein a script generating unit (20) is provided, which is adapted to the provisional control program (28) with an already manually adjusted by an operator control program (30, 32) of the system (40 ) and, on the basis of a recognized difference between these two control programs (28, 30, 32), to generate the edit script (52, 54) in such a way that when the edit script (52, 54) is executed by the editing unit (16) generated control program (34) of the editing unit (16) with the manually adjusted control program (30, 32) matches.

6. Device (10) according to one of the preceding claims, wherein an analysis unit (20) is provided, which is designed to ^¬

a) to compare at least two editing scripts (52, 54) of said type and / or to compare at least two control programs (30, 32) of the system (40) manually adapted by an operator to the respective control program (28, 30) the operator was changed in each case, and

b) by comparing how often certain changes have been made in total and, if the frequency of a particular change is greater than a predetermined threshold, signaling that change.

7. Apparatus (10) according to claim 6, wherein the analysis unit (20) is adapted to change based on a signalized change at least one of the templates (22 ').

8. A method for configuring an operating sequence of a process and / or production plant (40), comprising the steps:

- generating a provisional control program (56) from a schedule (26) which was of linked template (22 ') for parts of the operation by a user means of with- an operating unit (12) created by co ^¬ degeneratoreinheit (14) .

- Generating a customized control program (34) from the preliminary control program (56) by executing an editing script (52, 54) by means of an editing unit (16), the adapted control program (34) thereby adapted to specific, structural characteristics of the system (40) becomes.

The method of claim 8, wherein an analysis unit (20) compares an old version of the preliminary control program (28) with a control program (32) generated therefrom by an operator by manual adjustment and generates instructions based on a detected difference indicating how the manual control program (32) has been created from the old version (28) of the preliminary control program and these instructions are combined into the editing script (52, 54).

10. The method of claim 8 or 9, wherein by an analysis unit (20) a plurality of generated by an operator by manually adjusting control programs (32) with the unchanged output version (28) of the respective control program and a frequency equal, carried out by the operator changes is determined and, if the frequency of a certain change is greater than a predetermined threshold value, this change is signaled as a particularly frequent change.

11. The method of claim 10, wherein at least one of the templates (22 ') is adapted on the basis of at least one change recognized as being particularly frequent change, resulting in an adapted schedule and, in turn, a preliminary control program in which the manual adjustment is no longer necessary.
