Description

The invention relates to an automation method for a process plant in which solid, liquid and / or gaseous substances of min at least one output resource to a min at least be directed to a recording resource. The he The invention also relates to an automation device for the process technical management of a process plant, in such a model of the plant and at least one plant-specific sequence program are stored, and the process-technical guidance of the plant through the sequence program at least with the help of the model. The he Finally, the invention relates to an advantageous use of such an automation device.

From the monograph A. Helms, H.-M. Hanisch, K. Stefan "Control of batch processes", VEB-Verlag Technik, Berlin 1989, pages 32 to 41 and 58 to 67, is removed bar that automation process for procedural systems, especially for so-called batch processes, with a road network and associated resources reali can be settled. Advantageously, the Coupling the process units as resources with the help of a model can be analyzed. There is a Synthesis of the overall model based on sub-models. The control should be there with the help of DIN function plans can be realized, which is also in the programming of Programmable logic controllers (PLC) use Find.

Programmable logic controllers (PLC) for the process control technology are known per se. For example in atp automation automation practice 33 (1991), 5, pages 234 to 239, is about meaning, status, requirements as well as trends of such controls. Farther is in Technische Rundschau 51/52 (1990), pages 36 to 39, stated that simulation models are advantageous for Use replication of technical systems and processes can be detected. Such a model can be used as a hardware Model or implemented as a computer model and in the latter Case in particular be verified on a computer.

For process engineering management were, d. H. in particular their control, regulation, monitoring control and operation are increasingly becoming so-called automation tion devices used. It is mostly about compact, program-controlled data processing systems, which both in terms of the hardware structure of the operation medium and its mechanical structure, as well as in relation to the internal software structures and which are available the programming options specifically for controlling in industrial processes. Especially in the  Such automation devices are widely used in process engineering widespread because process plants for mixing and chemical synthesis of various starting materials one or more intermediate or end products one in the Usually have a very complex structure.

Automation differs in programming devices significantly from program-controlled data processing plants of a general kind. (See e.g. Dubbel, Taschenbuch für den Maschinenbau, Springer-Verlag 17th edition 1990, "Part Y: Electronic data processing ", 3.2.5 Selected programs Languages, especially pages Y 25 to Y 28 "languages for modeling and simulation ").

The user programs of automation devices are in usually divided into so-called "building blocks" in software ("structured"). A "building block" is therefore a radio tion, structure or intended use of a delimited part of a Programs, d. H. a kind of subroutine. In an automat Sierungsgerät can different types of such programmatic "building blocks" occur. Of special Significance are "function blocks" with which often recurring or very complex functions programmtech niche can be replicated. Such a function block ne have a variety of special properties, de in particular the "parameterizability" and the "verque" availability "are important. The parameterizability means that which is functionally simulated by a function block dete function with different operands ("block parameters tern "). The swellability means that a Variety of function blocks, which individual opera have sets, either as a copy or with the help of  in terms of software, with software can be connected or "chained" that hereby a function dependent on the respective application can be simulated to a larger extent programmatically.

A prime example of the software structure and the Pro grammage of an automation device is such. B. the Book by Hans Berger, Automation with SIMATIC 55-135 U, Siemens Aktiengesellschaft, 2nd edition 1988, in particular on see pages 15, 109 and 145.

Based on the prior art according to the above Book "Control of batch processes" is the Invention the task of specifying a method which for Automation of such a process plant is suitable in the fixed liquid and / or gaseous substances from at least one end Giving resources through a route network with controllable operations directed to at least one recording resource material transformations during transport may be subject.

As a prime example of route networks in process engineering Plants can include piping systems or conveyor systems be seen. This can be used to store substances and goods various types of certain output resources of the System to be transferred to recording resources. The Substances can have any physical state have z. B. gaseous, liquid, vaporous, flowable, powdery, granular and the like. With corresponding The mechanical design can also be granular Bulk goods are routed through the network of paths. As a pattern example of output and recording resources one  process engineering plant z. B. containers, mixers or chemical reactors can be specified. From issue Means of this type can either be continuous in batches or in the form of certain subsets be fed into the road network, and for mixing or chemical synthesis of a new intermediate or end product selected recording resources of the procedure technical equipment. The road network ver adds controllable resources, which in particular to influence the material path, the material feed and serve the fabric processing. In an exemplary Piping system as a route network can e.g. B. valves, Pumps, screens, filters, mixers, stoves and the like form controllable resources. They serve in particular to control the desired path and substance feed, but can also fabric and processing have functions. The resources of the route network become dependent on the currently desired mode of operation the system from the automation device preferably fully automatic controlled by a special user program.

A major problem with ver driving systems is that the technical Plant construction can be extremely complex. In addition, this is only stationary for a short time because of repairs, um Buildings and extensions, especially in the network of paths Changes in the technical structure or fluctuations in the Availability. In process engineering management such a system with the help of automation device there is the problem that programmtech nisch deposited and serve for process engineering management the models and sequence programs often continue to the Developing technical plant structure or current An  to adapt to the situation. So z. B. during a renovation a piping system as a route network u. U. new lei in the range of the car automation device defined and in the already existing to which program structures are integrated.

In order to cope with this, it has so far been the first step necessary, the program contained in the automation device Processes that are used for the process engineering management of the original structure of the route network of process engineering Were designed to analyze in detail. Here especially had to find the places inside the program process are recognized, which are no longer with the ver changed technical structure of the route network. Only then could the new ones in a second step Resources in the route network are technically defined and program-wise into the previous structure of the program process can be integrated. Such an approach is time-consuming. On the other hand, it holds many potential sources of error, so that when restarting a Automation device with such a customized Ab Run program to avoid undesired malfunctions usually a complete one in the process plant renewed, gradual commissioning was necessary.

An essential aim of the invention is that Automation process for the process technical plant preferred in the manner of a "function building blocks "and automation based on them device to indicate which one is as transparent as possible pro Technological replica of a network of paths and the network contained therein controllable resources located. In particular  in particular, the model of the network of paths should be designed in this way be that the most immediate possible representation of the real technical network of paths into a corresponding programmtech African structure of "swollen", parameterizable radio tion modules is possible.

The object is achieved with those specified in claim 1 Activities. Further advantageous embodiments of the invention an automation system on which the process is based advises and advantageous uses of the automation system Advices are given in the subclaims.

According to the invention, a controllable resource of the Network together with the one immediately before and / or afterwards branching in the path network programmtech niche modeled in a sub-model. In a verquel Development files are those for modeling the structure of the ge links serving the entire system of the partial models of the Path network with each other and with at least each an output and recording resource program technically deposited.

The use of such a model has the advantage that the real, tech African structure of a route network in a procedural system immediately modular, if possible precon Assembled, technically uniform sub-models in the type of function blocks can be reproduced. For Replication of individual equipment and the associated Branches of the network of paths, it is advantageous to part model with a corresponding operand set for "indivi dualize ". Changes in the structure of the road network can  programmatically simple in the automation device can be understood by the fact that to no longer exist Partial models belonging to the resources of the route network deleted or for newly added resources of the Part models belonging to the network are redefined. Of the modular structure of the model ensures that the part Oil models and swellings leading to one from a remodeling or partial failure of the route network hear, also in the programming replica stay changes.

So while in the prior art mentioned at the beginning there explained simulation models for the external after-image used in technical systems and processes are used in the automation according to the invention process and associated automation device that Because of the network model models with the corresponding Source file to control the processes. In the Invention becomes the model itself as process engineering management of the system.

Fig. 12 possible "path alternatives" serve.

Fig. 1 shows a schematic diagram of the general structure of a process plant. Output resources B11 are in a first level. . . B1n arranged, e.g. B. output containers, which feed solid, liquid and / or gaseous substances into a general "path network". The route network has a large number of controllable, "route-specific" resources. With this, predetermined subsets of the substances fed in can be used for recording resources B51. . . B5n are supplied, e.g. B. receptacles, which are arranged in a second level.

In Fig. 2, an overview circuit diagram for an example of a process plant is shown to illustrate the general structure of Fig. 1. Output container B11. . . B16 contain a variety of starting components in the form of storage paper, of which, for example, component A is liquid and components B, D, E, F are solid. At the end of the system there are B51 receptacles. . . B54 is intended to accommodate three different end products A, B, C. To produce these end products, predetermined amounts of the containers in the output B11. . . Components contained in B16, e.g. B. with due regard to "recipes" in the receptacle leads. For this purpose, in the example of FIG. 2, a first network of paths is connected to the output container, then three reaction containers B31, B32, B33 and finally containers up to the receptacle are provided with a second network of paths. The two way networks are designed so that, depending on the respective mode of operation of the process plant, predetermined subsets of substances from one or more output containers or reaction containers can be passed into an arbitrarily selected reaction container or receptacle. In the first network of paths, sieves W1 are exemplary as resources for this. . . W4 provided by which predetermined subsets of the in the output containers B11. . . B16 contained components can be passed through. The first route network is further designed so that the withdrawn portions can be introduced into one of the reaction vessels B31, B32, B33. For this purpose, the route network points in the area between the sieves W1. . . W4 and the reaction containers B31, B32, B33 further controllable operating means, not shown in FIG. 2 for reasons of clarity. Should z. B. a certain subset of component A from the output container B11 through the sieve W1 into the middle reaction container B32, it must be ensured at the same time by corresponding shut-off valves who ensures that no partial quantities accidentally get into the reaction containers B31 and B33 during mass transport.

In the reaction containers, the components supplied from the output containers z. B. chemically converted into intermediates by thermal and mechanical action. These represent the starting products for the synthesis of the desired end products A, B, C in the example in FIG. 2. For this purpose, predetermined quantities can be taken from the reaction containers B31, B32, B33 via the second network of paths into any receiving container B51. . . B54. Again, in Fig. 2 for reasons of clarity the functionality of the second road network necessary controllable operating means, in particular shut-off valves, not shown.

Fig. 3 again shows a general structural diagram of a process plant. Based on the preceding FIGS . 1, 2, this output resource B11. . . B1n, intermediate reaction resources B31. . . B3n and finally recording resource B51. . . B5n on. The output and reaction resources are in turn connected via a first route network, and the response and reception modes are connected to one another via a second route network. These route networks consist of a large number of "way-specific fish" resources, some of which are symbolically represented in the structure of FIG. 3. The first, second route network has controllable valves V2n, V4n and pumps P2n, P4n and sieves W2n, W4n and sieves S2n, S4n.

According to the invention, these resources are the way nets sub-models TM21. . . TM2n and TM41. . . TM4n for  assigned to the program description. According to the invention each of the partial models TMn includes the corresponding one Equipment V2n, P2n, W2n, S2n,. . . together with the branch immediately before and after it supply EV or AV of the route network. In the source file of the model according to the invention are finally for replication the links of all in the structure of the entire system Partial models of the two route networks with each other and with the respective output, reaction and recording resources B1n, B3n, B5n ("swellings") behind the program sets. This has the advantage that each network of routes big size and complexity by a according to the invention modular from "swollen", preferably standardized Sub-models of existing model in terms of programming can be formed.

FIG. 4 shows an illustrative representation for a partial model TMn, which according to a further embodiment of the invention consists of a route element and a resource element. The route element SEn represents, according to the invention, a standardized data record with program-technical input and output branches, with which at least the branches EV, AV of the route network immediately before and after the operating means belonging to the sub-model are simulated in the program. The resource element BEn of the submodel TMn also represents a standardized data record, with which the associated resource located between the branches EV, AV in the route network can be simulated in terms of program technology. Finally, the links between the data record of the route element SEn and the data record of the resource element BEn of the submodel TMn are also stored in the source file in terms of program technology. In Fig. 4, these swellings are represented by so-called operating branches at the output of the route element SEn sym bolisch.

Fig. 4 is already another, the configuration of the standardized data set of the distance element shows SEn of each part model TMn respective further embodiment of the invention. In this case, the branch EV of the route network lying directly in front of the associated equipment is reproduced per gram by an input node EK with at least one outer branch E1. . . En. As a result, the route element SEn can be program-technically linked to the data record of the route element SEn-1 from at least one further partial model TMn-1, which simulates a controllable resource of the route network upstream in the route network or an output resource B1n, B3n. Furthermore, the branching AV of the route network which lies immediately after the associated operating means is simulated in the program by an output node AK with at least one outer branch A1. . . At. Via this, the route element SEn can be program-technically linked to the data record of the route element SEn + 1 from at least one further partial model TMn + 1, which simulates a controllable resource of the route network following the route network or a recording resource B3n, B5n. Finally, the connection of the simulated branches EV, AV to the connections of the associated operating equipment in the route network is simulated in the program by a resource node BK with at least one external branch B1. . . Bn. With this, the route element SEn can be linked, with the aid of the swell file, with the data record of the at least one resource element BEn belonging to the partial model TMn.

Fig. 4 shows, of course, only a vivid, oriented on conven union hardware components representation of the purely in the software area of the design of the partial model TMn and its route and resources element SEn, BEn. Thus, in particular, the input, output and Resource nodes EK, AK, BK and their "connection" are reproduced programmatically by commands and addressable memory areas inside the route element SEn, which itself represents a part of a user program that is delimited by function, structure and purpose ("subroutine"). Furthermore, the "Connections" E1. . . En, A1. . . An and B1. . . Bn of the input, output and equipment branches are also program-technically simulated by addressable memory areas and are integrated into the subroutine of the "function block" TMn.

In FIG. 4, a further advantageous embodiment the standardized data set of the distances element SEn in the partial model TMn finally is shown symbolically. These are means by means of which a program-based simulation of the respective activation state of the associated operating element BEn depending on the occupancy of the simulated branches EV, AV immediately before and / or afterwards in the route network of the system is simulated. These means monitor the current state of the input and / or output node EK, AK in the data set of the route element SEn, and are symbolically represented in FIG. 4 by "measuring points" ZE, ZA. Hereby z. B. a higher-level user program in a serving for the management of the process engineering automation device is signaled whether the programmable modeled by the submodel TMn controllable resources in the network of the system is currently "occupied" or not, ie whether it is currently z. B. is involved in a material feed or not. In terms of programming, these means ZE, ZA can be used in the standardized data record of the route element SEn z. B. in the form of binary flags or in the form of status bits inside a control word.

The invention is explained further below with the aid of a first game, shown in FIGS . 5, 6, 7.

Here, FIG. 5 shows a simple road network in a ver drive technical installation and according to the invention before taken assignment of partial models to the controllable resources of the transport network. The system of FIG. 5 has, for example, a single output resource B11 and two recording resources B51, B52. The route network in between has three valves V1, V2, V3 and a pump P1 as controllable, route-specific operating resources. Here, the series connection of the valve V1, the pump P1 and the valve V3 binds the output resource B11 to the recording resource B51. Furthermore, the output of the pump P1 is connected via a branching K of the route network and a valve V2 lying in the branch line to the take-up mode B52.

According to the invention, each resource of the route network is now reproduced in the program by a partial model together with the branching in the route network which may be immediately preceding and / or afterwards. In the example of FIG. 5, the operating resources V1, P1, V3, V2 are the partial models TM1 shown in dash-dotted lines. . . Assigned to TM4. The route network of Fig. 5 includes only a single branch K which is assigned as an operating means P1 branch lying immediately thereafter by way of example the associated partial model TM2 in accordance with the invention.

FIG. 6 clearly shows the partial models used for programming the operating resources and for branching the route network of FIG. 5. Each sub-model TM1. . . According to the embodiment of the invention according to FIG. 4, TM4 consists of one standardized route and resource element SE1, BE1; . . .; SE4, BE4. Each route element SE1. . . SE4 has three input branches 1 , 2 , 3 , three resource branches 4 , 5 , 6 and three output branches 7, 8, 9 , for example. Thus, the route element SEI is technically linked via the input branch E2 at the input node EK to the output branch 1 of the output operating means B11. Correspondingly, the route elements SE2, SE3 are each programmatically linked via the input branches 2 to the data records of the route elements SE1, SE2 in the submodels TM1, TM2 belonging to the upstream operating means V1, P1 in the route network. Furthermore, the route element SE4 in the sub-model TM4 for the valve V2 is linked via the branch 2 of the input node EK with the branch 7 of the output node AK of the route element SE2 in the upstream sub-model TM2 of the pump P1. Finally, the input branches 1 of the recording resources B51, B52 are each program-related with the output branches 8 of the output nodes AK in the link elements SE3, SE4 of the submodels TM3, TM4 for the resources V3, V2.

FIG. 7 shows an example of a swelling file belonging to the partial models of FIG. 6. It contains all the technical links V between the sub-models with each other and the route and resource elements in each sub-model. The source file of FIG. 7 has, for example, seventeen command steps, two command types D,. . . and V, . . . occurrence. With the command type D,. . . the records of the partial models TM1. . . TM4 complete with the associated data records of the respective route and resource elements, and the data records of the output and recording resources program technically created. In the program steps 1, 14, 16, the data records for the output resources B11 and the recording resources B51, B52 are created. The data records for the partial models TM1 are correspondingly in program steps 2, 5, 8, 11. . . TM4 complete with the associated data records of the route and resource elements SE1, BE1,. . . SE4, BE4 created programmatically. Furthermore, with the command type V,. . . the programming links between the route and resources elements of the sub-models and the links to the output and recording resources according to the illustrative representation in Fig. 6 programmed.

Thus, instruction V, SE1, 2, B11, 1 in program step 3 effects the program-related linking of input branch 2 of route element SEI in submodel TM1 to output branch 1 of output device B11. Correspondingly, the instruction V, BE1, 1, SE1, 5 in program step 4 effects the programming link between the input branch 1 of the resource element BE1 and the resource branching 5 of the associated route element SE1 inside the submodel TM1. In the same way, all "connections" in the illustrative representation of FIG. 6 are executed programmatically by the linking instructions V in program steps 3, 4, 6, 7, 9, 10, 12, 13, 15, 17.

The exemplary process engineering system of FIG. 5 is thus modeled in accordance with the present invention in terms of programming technology by the model M which is illustrated in FIG. 6 and which consists of a sequence of partial models which, according to FIG are. It is now a special feature of the invention that, apart from "swollen" submodels, no further "function blocks" are required for program-related simulation of the process engineering system. In particular, no separate sub-models are required to simulate branches in the route network. Rather, any branches that may be present in the path network according to the invention are simulated in a single partial model together with the immediately preceding or subsequent operating resources. Thus, the only branching K in the exemplary route network of FIG. 5 according to the invention is shown in FIG. 6 by the output node AK of the route element SE2 in the interior of the partial model TM2 used for program-related simulation of the operating medium “pump P1”.

The formation of the partial models according to the invention, in particular in particular according to the embodiment of FIG. 4, thus enables a particularly simple, direct program-technical simulation of an arbitrarily branched and any number of controllable operating resources having a route network in a process engineering system. Since the standardized data set of each route element in a partial model already has an input and output node EK, AK, each with at least one external branch, any complex route networks can be simulated simply and clearly in terms of programming. If two items of equipment immediately follow one another without a branch, only one branch of the input and output branches are occupied in the associated route elements. In the example in FIG. 5, the pump P1 is connected directly to the valve V1 without a branch. Accordingly, in model M of FIG. 6, only the input branch 2 of the route element SE2 is linked to the output branch 8 of the route element SE1. The further branches 1 , 3 of the input node EK in the plug element SE2 and the branches 9 , 7 of the output node AK in the link element SE1 are not occupied in this case.

Finally, in particular the embodiment of the invention shown in FIG. 4 enables the simultaneous program-technical simulation of several operating resources working in parallel in the route network with a single partial model. Thus, theoretically at every branch B1 in Fig. 4. . . Bn of the resource node BK, a separate resource element BE "swells" in terms of program technology. In practice, however, a single piece of equipment will be arranged between a branch of the road network immediately before and after it, and thus only a single resource element BEn in the associated partial model TMn will be swollen with a resource branching of the resource node BK of the associated route element SEn.

The invention further relates to an automation system advises on procedural management of a procedural African plant in which a corresponding to the above explanations model of the plant and at least one plant-specific sequence program are stored, and the process-technical guidance of the plant through the sequence program at least with the help of the model. Here sequential programs generally have the task of ver driving system in a desired manner to influence that the substances fed in at the entrance converted into end products of the desired quality and quantity be set. In the present case, a procedural one African system with a route network influences a process program the controllable resources of the route network especially such that a very specific one, depending on the due to the operation of the system dependent adjustment of the Material path, the material feed and, if applicable, the Fabric processing with the goal of successful ready position of the desired end product.

According to the invention, the sequence program points in this case at least one route module in the sense of a program tech African "function block" in which a sentence or multiple sets of either copies of selected part models or from technical references to program selected partial models in the form of a data record  are technically deposited in such a way that about the tax resources and ramifications of one or the other the sub-models belonging to the several sentences are a permissible one or several alternative, permissible routes through the route network the system from a selected output resource to to a selected recording resource programmtech niche replicas.

Since process engineering systems are usually very complex are built up, in many cases it is possible to use a substance from a selected output resource with the aid of different controllable resources of the Path network to one and the same recording resource conduct. So there may be several alternative permissible "ways" in which the mass transfer takes place Can be found. According to the invention can now in a "path stone "called data set all those sub-models per be stored in grammar with which a permissible or several alternative, permissible routes through the route network the system from a selected recording resource to replicated to a selected recording resource will. The one permissible route or alternative route sub-models are advantageous in the form of Blocks stored in the path block in the program. This thus provides the procedural engraving for the user nical system clearly all possible ways alternatives between a particular dispensing operation medium and a particular recording resource model well program-wise together.

Such programming in terms of programming with the aid of the "route module" according to the invention not only offers the advantage that the operator of the process engineering system can choose between several equivalent, permissible route alternatives, but also quickly recognizes which of the route alternatives is not available in the short or medium term To be available. Thus, the case may arise that several controllable operating resources in the route network are currently not available due to a material transport currently taking place between certain output and receiving operating resources. Often some resources are also e.g. B. temporarily unavailable due to malfunctions, defects or maintenance work. Such "assignments" can be reproduced in terms of program technology from the sub-model belonging to the respective resource of the route network. The program-technical "measuring points" ZE, ZA in the example of FIG. 4 are suitable as "occupancy display" before. Thus, if a sub-model in which a route alternative set of sub-models simulating the route network has such a "program-technical assignment", this is the route alternative not currently available in the path module. An automation device constructed according to the invention thus has the advantage that due to the program-technical simulation of the route network with the help of the partial models and the source file, and the program-technical summary of permissible route alternatives between a pair of output and recording resources in "route modules" the operator a good overview of the actual overall structure of the process engineering system and its current state, in particular the availability of controllable resources and thus certain distances in the network of paths, is made possible.

An automation device constructed according to the invention can be particularly advantageous for. B. in a control room or  a control room can be used to formed process engineering plant of a central Be observation, operation and / or process engineering management, d. H. Control and regulation, especially of the equipment the network of paths with the aim of providing material Liche end products in a desired amount and together setting to make accessible. According to another Embodiment of the invention has the automatics for this sierungsgerät a process interface over which the at least one sequence program for the sub-models at least control the equipment belonging to the route network can. Furthermore, there is at least one path module each set of either copies of selected sub-models or from technical references to selected parts Models in such a program in at least one sequence of steps technically stored that when processing the step follow through the sequence program via the process interface a control of those resources of the plant follows, which is shown in the following by the respective sentence the permitted route or the alternative route are arranged.

These embodiments of the invention are explained in more detail below with reference to FIGS. 8, 9 and 10.

In Fig. 8, a path module W.B51 is illustratively shown, in which the set of selected partial models is stored in the program, which in the example of FIG. 5 shows the permissible path from the output means B11 as source Q to the recording means B51 as target Z reproduced programmatically. Since the example of FIG. 5 via the controllable resources V1, P1, V3 of the route network only allows a single route between the resources B11 and B51, the route module W.B51 in FIG. 8 can only carry out the one set of submodels TM4 , TM1, TM3, TM2, which are tabulated in the only permissible path alternative 1. According to the preferred embodiment of the invention, these selected partial models are already stored in the path module in a four-step control step sequence SN in the path module. When they are processed by the sequence program, in the first control step SN1 the partial model TM4 is used to control the operationally simulated operating means in the route network, ie the valve V2 in FIG. 5. In a corresponding manner, the sequence program controls via the process interface during the processing of the control steps SN2, 3, 4 the resources simulated by the partial models TM1, 3, 2 in the route network of FIG. 5, ie the valves V1, V3 and the pump P1 .

The operating state, which the respective equipment of the individual sub-model is to assume after activation via the process interface, is indicated in the step sequence SN of FIG. 8 as the "target state". Thus, the running program of the automation device causes the processing of step SN1 via the partial model TM4 and the process interface z. B. A closing of the valve V2, ie the taking of the target state 0. Accordingly, in the control step SN2, the valve V2 is opened via the sub-model TM1, ie the target state 1 is taken. The processing of the control step SN3 also brings about the sub-model TM3 an opening of the valve V3.

Finally, the processing of the control step SN4 by intervention of the sequence program on the submodel TM2 causes the connection of the pump P1, ie also the desired state 1. After processing all the steps in the step sequence SN, all the resources of the route network are therefore between the output and recording resources B11 driven B51 in Fig. 5 so that this path in the drive ver technical installation of Fig. 5 is "activated", ie a mass transport of B11 to B51 takes place. The inventive program-based simulation of permissible paths and path alternatives in a path network with the aid of a "path block" thus enables, together with a process interface of the automation device, direct process-technical management of the simulated procedural system.

In a further processing run of the sequence of steps, the controllable operating resources can also be given the complementary desired state. Accordingly, in the example of FIG. 8, a possible inverse target state is in the control steps SN1, 2, 3, 4. . . /1, . . . / 0,. . . / 0,. . . / 0 specified. When they are processed by the sequence program, at least the valves V1, V3 are closed and the pump P1 is switched off via the process interface. The path between B11 and B51 is "deactivated" again.

Fig. 9 again shows a clear illustration of the general case of way blocks W.B51, W.B52. . . W.B5n, which are used for programming the route network in a general technical system according to the representation of FIG. 1, and in which, according to a preferred embodiment of the invention, "route alternatives" are reproduced programmatically by the route network. Thus, in the first path module W.B51, n sets of sub-models are summarized per gram. In this case, the first sentence forms all possible paths 1 , 2 ,... Between the output mode serving as source Q and the recording mode serving as target Z and B51. . . n in the network of paths of the general technical system of FIG. 1. Alternative 1 can be assigned the highest priority and alternatives n the lowest. Accordingly, the last set of partial models in the path module W.B51 simulated all permissible path alternatives between the output resource B1n and the recording resource B51. The W.B51 path module thus models all permissible B11 output devices. . . B5n outgoing and in the same way to the recording resource B51 path alternatives include the W.B52. . . W.B5n also has n sets of path blocks. As a result, all permissible paths are alternative that are provided by each output resource B11. . . B1n go out and each on a recording resource B52. . . B5n replicated programmatically.

According to a further embodiment of the invention, each step sequence SN in the at least one path module of the automation device comprises at least one separate “start step sequence” and a “stop step sequence”. Either the copies of the selected sub-models or the program-related references to the selected sub-models are stored in the program in such an order that when the start or stop sequence of steps is processed by the sequence program via the process interface, a proper successive activation or Isolation of those resources in the network of paths it follows, which are arranged in and on the permissible path formed by the respective sentence. This should be explained in more detail using the example of FIGS . 5, 8.

Thus, in Fig. 8 as "Start-step sequence" the sequence of control steps SN1, 2, 3, 4, and as a stop-step sequence, the sequence of control steps SN4, 3, 2, indicated 1 for the example of local Wegbausteins W.B51 . When the W.B51 route block is processed by the sequence program, the sub-models stored in the control steps in the program steps are thus controlled successively. According to FIG. 5, this has the consequence that, in the processing of the start step follow for activating the only ones permitted Wegalterna tive 1 in the local network of paths between the operating means B11 and B51 initially the partial model TM4 the valve V2 is closed. As a result, the branch of the road network is blocked off from the branching K at the outlet of the pump P1 to the operating equipment B52. In the subsequent control steps SN2, SN3, the valves V1, V3 which are in the alternative path are opened via the partial models TM1, TM3. Finally, in the last control step SN4, the pump P1 lying in the alternative path is activated via the part model TM2. This arrangement of the control steps in the "start step sequence" thus properly unlocks the resources of the route network.

In the same way, this equipment is properly shut off successively by successive processing of the control steps stored in a "stop step sequence" in terms of program technology. For example, in the example in FIG. 8.5, the control step SN4 is first processed and the pump P2 operating medium is thereby switched off via the submodel TM2. The control steps 3, 2 are then processed, which results in the valves V3, V1 being shut off via the associated submodels TM3, TM1. Finally, at the end of the stop sequence of steps, control step 1 is processed, as a result of which valve V2 lying in the branch is opened again via submodel TM4. In this way, the initial state is reached again by proper, gradual shutdown of the means of travel between B11 and B51.

According to a last embodiment of the invention that is Automation device designed so that the process program the sequence of steps of more than one block neither of copies of partial models or of program technical references to partial models "quasisimultan" be can work. The resources of the affected part models can thus be timed via the process interface overlapping. According to the invention the sequence program in such a case in which affected NEN block automatically prefers the sequence of steps select that set, and thus the resources of the Sub-models in that of the alternative, permissible ways between a particular output resource and one control certain recording resources, where none the reproduced branches in the corresponding part models through a quasi-simultaneous acti fourth step sequence of another sentence is currently occupied. This embodiment enables the operator of the ver driving system, several way age at the same time native about the sequence program and the process cut place to activate without overlap inside ren of the road network occur. As far as the technical The structure of the system allows several ways between spending and recording resources at the same time unlocked and thus simultaneously a material feed to be activated. The automation device prevents this  automatically that sub-models of certain equipment of the road network on which in several sets of sub-models is referenced in several way blocks, inadvertently can be controlled simultaneously.

Should therefore be between an issue and a recording the way lying on the equipment is activated the automation device prefers those automatically Set of sub-models, and thus the one, permissible Wegal alternative in the network of paths in which none of the sub-models already exist is activated. Of course, the automation a certain route alternative is also pre-set manually will give. If there is no free alternative path, consequently one or more sub-models in each set at the moment the sequence program to avoid uncontrolled faulty switching in the route network no wayholders native free. In this case you have to wait until one or several of the others, quasi-simultaneous by the sequence program activated sets of partial models are no longer required become, d. H. which over the hereby programmatically reproduced routes in the road network of material transports Are completed. This embodiment of the invention Automation device has the particular advantage that the User taking advantage of the process plant if possible, all available resources and Can fully utilize branches in the network of paths. He can therefore have several according to its current needs Activate sets of submodels in several path modules, in order to have as many paths as possible in the network of paths between the plant different output resources B1n and Auf Activate resource B5n simultaneously. It can thus several process engineering processes in the system run without the misdirection of substances in the Path network occur.  

This embodiment of the invention is illustrated in the block diagram of FIG. 10. This shows, by way of example, the route module W.5n, with which all path alternatives 1 that are permissible between the output resource B1n serving as source Q and the destination resource B5n serving as destination Z are permissible. . . X are reproduced programmatically. If this route module W.5n is now activated by the system operator, the sequence program checks every alternative to determine whether it is free or occupied. If the check is positive, the first free alternative found is preferably activated, and thus the processing of the associated set of sub-models activates the devices of the route network simulated here by means of programming technology via the process interface of the automation device. To check whether a partial model TMn is free or occupied, the program-related "occupancy displays" ZE, ZA of the input and output nodes EK, AK in the respective link element SEn, as shown in FIG. 4, are particularly suitable.

Referring to Figs. 11, 12, 13, the invention is finally illustrated by way of the second sample embodiment.

Thus, FIG. 11 as an example a process plant, which consists of two O resources B11, B12 and two receiving equipment B51, B52, which are connected to one another via a pipe system. This way network has the valves V11, V16, V14, V15, V21, V24, V25 and the pumps P12, P23 as controllable resources. There are also four branches K1. . . K4 available. Due to this structure of the route network, it is possible, if necessary, a mass transfer in more than one way z. B. from B11 to B51. The structure of the route network with the integrated controllable resources thus enables the activation of route alternatives.

According to the invention, each resource of the route network, together with the branching in the route network that may be immediately before and after it, is technically formed by a partial model. The partial models TM411, TM416, T414, TM415, TM421, TM424, TM425 are used to simulate the valves V11, V16, V14, V15, V21, V24, V25, and the partial models TM412, TM423 to simulate the pumps P12, P23. According to the invention, the branches of the route network are simulated in a single partial model together with the equipment immediately before or after it in a program. Thus, the branches K1, K2, K3 are emulated according to a preferred embodiment of the invention by the output nodes AK in the route elements belonging to the submodels TM412, TM416, TM424. Correspondingly, the branching K4 is simulated by the input node EK of the route element belonging to the partial model TM425. The assignment of partial models to branches selected in the example in FIG. 11 is only exemplary. Rather, could just if using the principle underlying the invention z. B. the branches K1, K2 as the input node EK and the branches K3, K4 as the output node AK of the model models TM414, TM415 are simulated in the program. In addition, other assignments, not shown, are possible. To model the structure of the system shown in the example in FIG. 11, a swelling file is again available according to the invention, in which the links of all partial models of the route network to one another and to the output and recording resources B11, B12 and B51, B52 are stored in the program. The swell file is not shown for reasons of clarity, since in principle it corresponds completely to the swell file shown in the example of FIG. 7 and explained in detail.

Furthermore, for the sake of clarity, the preferred replica of each sub-model was not shown again by the standardized data record of a route and resource element. In principle, the resulting structure in turn corresponds fully to what has already been explained in detail using the example of FIG. 6. Rather, FIGS. 12, 13 are intended to illustrate the program-related deposit of sentences, either from copies of selected partial models or from program-technical references to selected partial models, in "path blocks" of an automation device constructed according to the invention. It is consequently shown on the basis of the exemplary route network from FIG. 11 how in accordance with the invention several alternative, permissible routes can be simulated by the route network in terms of program technology.

Thus, FIG. 12 shows a path module W.51, in which either copies of selected partial models or of program references to selected partial models in the form of data records are stored in the program in four sets. The first two sets describe the path alternatives 1 and 2 that are possible between the output resource B11 as source Q and the recording resource B51 as target Z in the route network of FIG. 11. The other two data records accordingly describe those between the output resource B12 as source Q and the recording mode using B51 as destination Z possible route alternatives 1 and 2.

In the example of FIG. 11, a mass transport from the output equipment B11 to the recording equipment B51 can take place either via the controllable equipment V11, P12, V16 or via V11, P12, V14, V15. Correspondingly, according to the invention, the partial models of the resources of the route network located in and on these routes in the upper region of the route module W.51 of FIG. 12 are summarized in two different sets in terms of programming. Using another, preferred embodiment of the invention, the partial models are already stored in a certain control step sequence SN in each set. When they are processed by the sequence program, the process interface of the automation device is used to properly control the resources formed by the sub-models, and thus to activate or block the alternative path simulated thereby.

Alternative 1 has five control steps SN in the upper area of W.51 in FIG . When processing the first step, valve V14 is blocked via the associated sub-model TM414 (target state 0). When processing step 2, the valve V15 is also shut off via the associated submodel TM415 (target state 0). Now, in the following control steps 3, 4, 5, the resources V11, V16, P12 located within this alternative path can be activated via the associated sub-models TM411, TM416, TM412. In this way, a path age native is properly activated via this set of submodels in path module W.51 (start sequence). If this alternative path is blocked, at least selected or the same control steps, possibly in a changed order (stop sequence of steps) are processed by the sequence program and the desired states of the equipment are complemented.

In order to activate or deactivate the second path switch native 2 between the resources B11 and B51 in the example in FIG. 11, seven control steps SN are required. These are compiled in FIG. 12 in the upper area W.51 under "Alter native 2". Here, too, in the first control steps 1, 2, 3 the neighboring controllable resources of the route network that are not required for the route switch, i.e. in this case the valves V24, V25, V16, are blocked by processing the associated submodels TM424, TM425, TM416 (target state 0). Now, in the subsequent control steps 4, 5, 6, 7, the alternative controllable operating resources of the route network located inside the route, ie the valves V11, V14, V15 and the pump P12, can be processed by processing the associated submodels TM411, TM414, TM415, TM412 can be activated via the sequential program and the process interface of the automation device (target state 1) (start sequence). In the event that this path age is to be deactivated native, the sub-models bundled in this set can be processed in a different order (stop sequence of steps) and the associated resources can be given the inverted target state.

The sets of submodels shown in the lower half of the path module W.51 in FIG. 12 regarding the path alternatives possible in the path network of FIG. 11 between the output resource B12 as source Q and the recording resource B51 as target Z. Here are at the path age native 1 the controllable resources V21, P23, V24, V14, V16, and in the path alternative 2 the resources V21, P23, V24, V15 involved. Here, too, the partial models of the equipment located in and on these paths are already arranged in the respective partial model sets in the form of control step sequences SN. Alternative 1 consists of the step sequence SN1. . . 8 and alternative 2 from step SN1. . . 7. To activate or block the respective route alternative, in the manner already described, by activating the associated partial models via the sequence program, adjacent controllable resources of the route network must be blocked or released and controllable resources located within the desired route alternative must be released or blocked (start - / stop step sequences).

Fig. 13, finally, shows the Wegbaustein W.52. This simulates the possible paths between the output resources B11 and B12 as sources Q and the recording resources B52 as destination Z in the route network of the process engineering system of FIG. 11. Due to the structure of the system, mass transport between B11 and B52 or B12 and B52 is only possible in one way. Correspondingly, the way module W.52 in FIG. 13 has only a set of partial models in its upper and lower half, which describe the only permissible route age native 1.

In the example in FIG. 11, due to the degree of expansion of the path network there, mass transport from B11 to B52 is only possible via the controllable operating means V11, P12, V14, V25.

Thus, the partial models of the controllable operating resources located in and on this only permissible route are compiled in the upper half of the route module W.52 in FIG. 13 in a single sentence "Alternative 1". To unlock this route, the equipment in branches of the route network must be blocked. The valves V24, V16, V15 are thus blocked in the control steps SN1, 2, 3 via the submodels TM424, TM416, TM415 (target state 0). The valves V11, V14, V25 within the path are then activated in control steps 4, 5, 6 via the sub-models TM411, TM414, TM425 (target status 1). Finally, in the last control step SN7, the pump P12 and thus the mass transfer from B11 to B52 can be activated (start step sequence).

Correspondingly, in the example of FIG. 11, mass transport between B12 and B52 is only possible via the route with the controllable operating means V21, P23, V24, V25. The path module W.52 in FIG. 13 thus has only one set of partial models in the lower half as the only permissible "alternative 1". Here too, in the first control steps SN1, 2, the adjacent valves V14, V15 located in branches are shut off via the submodels TM414, TM415 (target state 0). Finally, the valves V21, V24, V25 and the pump P23 lying within the path can be activated in the control steps SN3, 4, 5, 6 via the submodels TM421, TM424, TM425, TM423.

In Fig. 11 the case is shown in dashed lines that the route network of the system is expanded by installing an additional pipeline with the controllable valve V26 between the pump P23 and the receiving operation B52 as part of a conversion. The route network now has the further branches K5, K6. According to the invention, in the example in FIG. 11, the branching K5 is modeled as an output node AK of the route element in the sub-model TM423 of the pump P23. The branching K6 is simulated as an output node AK in the route element of the new model TM426 that was added for the valve V26.

Due to this expansion of the system, it is now possible to carry out a mass transfer from B11 or B12 to B52 in addition to the previous routes, also with the help of a new route that runs via the additional valve V26. As a result, additional path alternatives 2 are available in the path module W.52 both in the upper and in the lower half, which are framed by dashed lines in FIG. 13. Alternative 2 between B11 and B52 has nine control steps SN, and Alternative 2 between B12 and B52 has five control steps SN. The sub-models in the individual control steps are again arranged in the manner already described.

An essential advantage of the invention can be seen from the example of the extension of the route network of FIG. 11 by the branch with the valve V26. For the added valve V26, an additional sub-model TM426, which preferably consists of a standardized data set, only needs to be created in the program. This does not affect the existing modeling of the unchanged resources of the route network. All TM411 sub-models defined so far remain. . . TM425 unchanged. The links of the new sub-model TM426 only have to be stored in the source file. For example, the output node AK of the route element in the sub-model TM423 to the pump P23 via the branch Al is no longer exclusively linked to an input branch of the sub-model TM424 to the valve V24. Rather, a second branch A2 is now additionally linked with an input branch E1 of the input node EK in the sub-model TM426 of V26. Accordingly, the links of the output node AK in the link element of the new sub-model TM426 with the recording equipment B52 and the sub-model TM425 of the valve V25 must be supplemented in the swell file. In addition, no further additions are necessary in terms of programming.

This has the consequence, in particular in the route modules W.51, W.52 in FIGS . 12, 13, that the previous sets of submodels which originally described route alternatives remain almost completely unchanged. There, only one additional valve V426 is shut off, the control step TM426 = 0, preferably automatically program-controlled, is inserted simultaneously with the definition of TM426. These control steps are not shown in FIGS. 12, 13 for reasons of clarity. Rather, the redefinition of the sub-model TM426 and its integration into the source file has the result that further, additional path-alternative descriptive sets of sub-models are added in the path module W.52 in FIG. 13. This programmatic addition of permissible route alternatives to the route module can also take place automatically under program control in the automation device after definition and swelling of the new sub-model.

In another case, the process plant  rebuilt so that controllable resources of the road network omitted without replacement, so the model according to the invention or automation device to this in a simple manner be adjusted so that the records of the deleted Part models belonging to the equipment and the associated ones programmatic links in the source file to be deleted. Do these measures have a limitation in the previous variety of alternative routes inside the Because of the network, programs are preferred controlled the sets of sub-models, which are no longer reproduce available path alternatives in the Route blocks automatically deleted. The structure of the he model according to the invention for program-technical replication a process engineering plant and one on it Accessing automation system for their process technology African management has thus for the operator of the plant special advantage that temporary or permanent and for malfunctions, maintenance work or conversions in the system changes in the availability of the controllable resources of the route network on fast and be reproduced in a clear, programmatic manner can.

Batches of at least one solid, liquid and / or gaseous substance via the network of paths and its loading drive from at least one selected output drive to at least one selected recording area drive means are directed. Such an operation Plant often becomes a "batch process" or batch control  called. It is preferably used in administration of formulations, especially in chemical Industry for the production of any intermediate and end products are needed. Finally finds one Automation device constructed according to the invention preferred use for controlling a process technology system in which the issuing and recording operations medium tank and the network of paths a piping system represent. Such an overall system can also be used as "Container control" are called.
