Abstract

The inventive method for virtual commissioning (VIBS) of a technical system (ANL) relates to an arrangement with a CAD system (CAD) for creating and displaying a CAD drawing with CAD drawing objects (R) for technical equipment of the system (ANL). Furthermore, a data platform (DB) with a library for resource data (BD), in which at least the attributes of the instrumentation belonging to a technical equipment type instrumentation objects are recorded, and a controller (PLC), which executes a control program for the technical system (ANL), available. According to the invention, a resource type from the library for resource data (BD) is assigned to a selected CAD drawing object (R). Finally, CAD motion objects (RF1, RF2, RT, RS1, RS2) are formed for each instrumentation object of the resource type at least taking into account its attributes and are displayed in the associated CAD drawing object (R) of the CAD drawing. The invention makes it possible to virtually "control" a CAD drawing via a controller (PLC). The particular advantage of the invention is that neither the technical equipment nor the technical system must be present. Rather, can be tested by all states of a corresponding system previously in an animated by using the method according to the invention CAD drawing. This makes it possible to put the system into virtual operation.

Description

Technical Plants, e.g. in the manufacturing industry, are highly complex and make a network of concerted and interlocking ones technical equipment. Through the interaction of these technical equipment of the respective technical plant the desired Achieved working results, e.g. the manufacture of motor vehicles in a car manufacturing plant.

Becomes such a technical system rebuilt or existing technical system rebuilt so must this usually elaborate CAD drawings are created. In these are all technical equipment of technical equipment in all constructive Details shown. The CAD drawings allow a constructional construction of all participating technical equipment in the respectively desired Position and location in the technical facility.

In The rule, however, is that of a specific technical equipment necessary instrumentation e.g. in the form of electrical and / or pneumatic Drives and actuators and e.g. electromagnetic or radio technical Sensors, not visible in the CAD drawings. The CAD drawings are on the constructional and mechanical constructive details technical equipment and their spatial arrangement in the technical Plant focused.

It Thus, the problem arises that from the structural and spatial Arrangement of technical equipment in the technical system, which is laid down in the CAD drawing, on their logical interaction under the control and / or control engineering influence e.g. a programmable logic Control must be closed. In practice, it is e.g. when planning a production plant is not always complete ruled out that at the later practical Commissioning of the real constructed technical system at critical Areas difficulties arise. In extreme cases, the plant must be at this Job has to be rebuilt again. Furthermore, with help a detailed constructional and spatially constructive design of a technical system in the form of a CAD drawing ensure that they are also used in later operation under control and drainage conditions works optimally. In the Planning of technical systems is not just a question today that involved the technical equipment involved properly but in particular also optimally time co-operate, so the entire system one possible has minimal tact time.

Of the Invention is the object of a method and a system specify which is a virtual testing of a CAD drawing only this technical facility allows.

The Task is solved with in claims 1 or 13 specified method or system. Advantageous further Embodiments of the method and the system, and an advantageous Use of the system are specified in the subclaims.

The Principle of the invention is based on that a CAD drawing, in the technical equipment of a technical system initially only shown are, can be processed automatically, so that the operation of the individual resources and, above all, their interaction in the entire system can be simulated. The originally pure rigid CAD drawing is thus dynamized and provides such real image of a technical facility that can even have one Control, which may already be present on the system, together can be operated. The controller does not notice that they are not with the actual technical facility, but with the dynamically extended CAD drawing cooperates.

For this purpose, according to the invention, in the CAD drawing, the technical equipment, which is initially shown purely as a technical drawing, is supplemented by all those mechanical and electrical objects which are later present on a real technical equipment of this type and necessary for its operation. These mechanical and electrical objects are commonly referred to as instrumentation objects. The CAD drawing is thus automatically supplemented, in particular, with sensors and actuators, for example light barriers, proximity switches, drives and the like. Now it is also possible to access the technical resources in the CAD drawing via a PLC, for example, which is already present in real life. The technical system represented by the CAD drawing can therefore, after this supplement, be put into virtual operation, as it were, by using the control which is already provided for the future operation of the real system anyway. In this case, the operation of the technical system is visualized by animation of the CAD drawing according to the invention. For this purpose, no physical structure of the technical system is necessary. Optionally, the programmable logic controller, for example, be emulated on a personal computer by appropriate software. The particular advantage of the invention lies in the fact that the current state of the simulation using a commissioning block directly in the CAD drawing can be displayed animated. So there are no separate, necessary only for visualization of the simulation display means necessary.

The The invention is based on the figures briefly mentioned below explained in more detail. there demonstrate:

1 2 is a block diagram of an advantageous embodiment of a system according to the invention for virtual commissioning of a technical installation;

2 the layout of a CAD drawing object in a CAD drawing representing a roller conveyor as an example of a technical asset;

3 the CAD drawing object of 2 to which the resource type has been assigned, and which has been supplemented by the virtual commissioning means with those CAD movement objects which represent the instrumentation objects belonging to the resource type ROLLWAY, and

4 exemplary the interaction of the CAD motion objects of 3 with the virtual commissioning device and the controller during the course of a virtual commissioning.

1 shows an advantageous construction of a system designed according to the invention in the form of a block diagram. This will be explained in more detail below.

The System features at least about three components, which are advantageous with the aid of a data processing system, e.g. a PC. The first component is a commissioning module VIBS. The second Component is a CAD program for creation, modification, display and storage technical CAD drawings. The third component is one Data platform DB. This contains at least one library BD for resource data. It may additionally also a library PD for Project data is available.

With Help of an external input unit KB, e.g. a keyboard or a mouse, the CAD application and the CAD drawings can be accessed designed, modified, can be displayed and saved. Here are CAD drawing for the representation of a technical plant and the associated technical Resources. For displaying, in particular, the CAD drawing is a display unit LCD e.g. in the form of a monitor. An essential element of the system according to the invention is a commissioning module VIBS. This complements one in the CAD drawing in the form of a CAD drawing object represented technical equipment, after this by a user a default resource type automatically assigned to the attributes of the required mechanical and / or electrical instrumentation objects, in particular Actuators, sensors and parts.

These are in 1 the commissioning block VIBS and a data platform DB connected to each other via a data interface S3. The data platform DB contains at least one library BD for resource data and advantageously additionally a library PD for project data. The data platform DB is preferably designed as a data memory containing files, streams or the like for data storage and / or data transmission. The data platform DB and the contained libraries can be edited by the user via a separate software and eg the input unit KB. In the library BD for equipment data, the permitted equipment types and their physical and technical properties are listed in the form of attributes. The attributes represent so-called default attributes, ie are default values. These can be adapted by the user depending on the application. In addition, additional attributes can be recorded in a library PD for project data. These attributes then represent custom attributes, ie are user-specific project or plant-specific values for one or more use cases.

to execution the preparation of the CAD drawing is the CAD application according to the invention via a Data interface S2 connected to the commissioning block VIBS. This causes on the one hand the automatic completion of the originally pure static CAD drawings around the associated mechanical and / or electrical instrumentation objects. According to the invention Instrumentation objects in the form of so-called CAD motion objects in the associated CAD drawing object added to the CAD drawing. This will be approached below explained become. The commissioning module VIBS continues to handle the entire process Simulation, also called virtual commissioning, starting by adding on the one hand represents the interface to the controller PLC and on the other hand visualize them by animating the CAD drawing. By the Interaction of the commissioning module VIBS with such dynamic CAD drawing creates a virtual commissioning model, which realistically simulates a real plant and its technical equipment.

The principle of the method according to the invention and the interaction of the elements of the system according to the invention is described below in ei in the 2 to 4 illustrated example explained. It is in the 2 and 3 CAD drawing object that symbolizes a so-called roller conveyor R as an example technical equipment. This has an elongated frame RR, in which rolling elements RO are arranged in parallel one behind the other. For example, a piece-shaped part RF, or a pallet or a carrier, for example in the conveying direction represented by an arrow RF, can be moved on this roller conveyor R. For example, the roller conveyor R should automatically convey the part RF until it has interrupted a sensor, eg a light barrier, at the end of the roller conveyor.

at a preferred embodiment the method according to the invention In a first step, an assignment of a resource type takes place to the affected CAD drawing object. This is the affected CAD drawing object in the CAD drawing first to mark, i. select. In terms of data technology, the affected CAD drawing object can be advantageous be characterized by an individual CAD ID. Well done the actual assignment of the equipment type by selection a list of the types available in the data platform DB. The selected equipment type is characterized by an individual KNOWLEDGE ID. Now it is too in terms of data, an assignment of the KNOWLEDID of the selected equipment type with the CAD ID of the selected CAD drawing object.

in the one next Step reads out the instrumentation object VIBS via the individual CAD ID the CAD drawing the geometry data of the associated CAD drawing object. These are in particular the position of the CAD drawing object in the Drawing plane of the CAD drawing, i. its coordinates, and the Dimensions of the CAD drawing object, e.g. Length L, width B, height H. Continue reads the instrumentation object VIBS via the KNOWLEDID from the Library BD for Resource data of the data platform DB assigned to the Belonging to equipment type Instrumentation objects and their attributes.

In the example of 2 to 4 was the CAD drawing object that a roller conveyor R shows, the corresponding type of equipment a roller conveyor with eg two movement speeds and a conveying direction assigned. This resource type has three instrumentation objects of type DRIVE, SENSOR, and PART, which have the following attributes, for example:

Instrumentation object DRIVE

• • Position DRIVE
• • Position and size of the associated DRIVE AREA
• • conveying direction and speed of the DRIVE AREA

Instrumentation object SENSOR

• • Position SENSOR
• • Position and size of the associated SENSOR AREA

Instrumentation object PART

• • position, i.e. especially starting position, and size

attributes which position and size information can, can absolute values regarding the Coordinate system of the CAD drawing or relative values in relation to the geometry data of the CAD object.

Advantageous is used in the commissioning block VIBS for each instrumentation object of the assigned equipment type has its own VIBS data object created. The VIBS data objects are used to manage all data, the for a virtual commissioning are necessary and during the Procedures of a virtual commissioning are subject to possible changes. Thus, in the individual VIBS data objects in particular the means the CAD ID read geometry data of the associated CAD drawing object and the attributes of the associated instrumentation objects read by the KNOW-ID stored and managed. They are subject to virtual commissioning during the course of the process especially the geometry data of instrumentation objects of the type DRIVE and PART, and the states of instrumentation objects of the type of SENSOR changes. The through the VIBS data objects provided data platform allows a data exchange both with the CAD drawing over the interface S2, as well as with the control over the Interface S3, and thus provides the basis for the virtual Commissioning ready.

It is advantageous if, in each VIBS data object, the geometry data of instrumentation objects which are or can undergo changes during the course of a virtual commissioning are each managed in a CAD motion object. According to the invention, the associated CAD drawing object in the CAD drawing is supplemented by the CAD motion objects of the associated instrumentation objects. These represent a dynamic image of each instrumentation object and allow in the originally rigid CAD drawing a visualization of the movements of all participating instrumentation objects during the course of a virtual commissioning. So that the CAD moving objects quasi move during the course of a virtual commissioning in the CAD drawing whose geometry data, in particular their position data, cyclically detected by the commissioning block VIBS in the associated VIBS data object, possibly changed and output to the CAD system. In this way, movements can be simulated in the CAD drawing. The geometry data of a CAD motion object is cyclically updated with the help of the geometry data of the CAD drawing object and the attributes of the associated instrumentation object. In particular, the starting points and prescribed changes in the attributes, such as in particular conveying directions and speeds, are taken into account. This applies in particular to CAD motion objects that visualize instrumentation objects of type DRIVE and PART. On the other hand, changes in geometry data can also be caused by the fact that CAD motion objects in the CAD drawing are changed by a manual intervention of a user, eg by displacement with a computer mouse. Such changes to geometry data are captured by VIBS by cyclically reading the current location of the CAD motion objects in the CAD drawing object.

The VIBS data objects for the in the 2 to 4 Example shown can have the following contents:

VIBS data object DRIVE

• • Geometry data the assigned CAD drawing object
• • Control PLC data: output address, binary status output (bit, byte, word)
• • CAD motion object DRIVE: position (X, Y, Z), dimensions (L, B, H ...)
• • CAD motion object DRIVING AREA: Position (X, Y, Z), dimensions (L, B, H ...)
• • reference on CAD drawing object in CAD drawing via individual CAD ID

VIBS data object SENSOR

• • Geometry data the assigned CAD drawing object
• • Control PLC data: input address, binary status the input (bit, byte, word)
• • CAD motion object SENSOR: position (X, Y, Z), dimensions (L, B, H ...)
• • CAD motion object SENSOR RANGE: position (X, Y, Z), dimensions (L, B, H ...)
• • reference on CAD drawing object in CAD drawing via individual CAD ID

VIBS data object PART

• • Geometry data the assigned CAD drawing object
• • CAD motion object PART: Position (X, Y, Z), Dimensions (L, B, H ...)
• • reference on CAD drawing object in CAD drawing via individual CAD ID

So shows 3 The CAD drawing object for the roller conveyor R extended by the CAD motion objects. The three instrumentation objects DRIVE, SENSOR and PART of the selected equipment type are assigned to the corresponding three VIBS data objects five CAD motion objects DRIVE RA1, DRIVE AREA RA2, SENSOR RS1, SENSOR AREA RS2 and PART TR managed and displayed in the CAD drawing object. The CAD motion objects DRIVE RA1 and SENSOR RS1 indicated the size and position of the actual devices, while the CAD motion objects DRIVE AREA RA2 and SENSOR AREA RS2 symbolize the size and position of the action spaces of these devices.

In In practice, it is when the CAD motion objects in the CAD drawing be presented with different colors. This allows instrumentation objects of the type drive, sensor and part at the end of a virtual commissioning be followed optically by a project engineer. It is still advantageous, in addition a different color representation of the instrumentation objects dependent on to make the status of their input or output signals.

The Basic principle in virtual commissioning according to the invention is based on a calculation of overlapping areas with the current geometry data of the objects managed in the VIBS data objects CAD moving objects. The CAD drawing provides the required Coordinate system and the geometry data derived from it.

If e.g. the current geometry data of the CAD motion object DRIVE AREA overlap with the current geometry data of another CAD motion object or do not overlap, e.g. with a CAD motion object of type PART, the geometry data becomes of the CAD motion object PART, depending on the attributes conveying direction and conveying speed cyclically recalculated and output to the CAD drawing. this causes a virtual movement of the CAD motion object with the respectively predetermined dynamics CAD drawing or a stop of the same.

In the example of 3 there is such an overlap. The CAD movement object PART RT lies inside the CAD movement object DRIVE AREA RA2. If the control program of the PLC controller activates the output address accordingly, the geometry data of the CAD motion object PART RT is cyclically updated in dependence on the attributes conveying direction and velocity and output to the CAD drawing such that the PART RT in 3 moved to the right at the desired speed.

If on the other hand, e.g. the current geometry data of a CAD motion object of type SENSOR AREA with the current geometry data of another Overlap CAD motion object or do not overlap, e.g. with a CAD motion object of type PART, becomes the binary one Status of the input of the CAD motion object SENSOR AREA set or reset.

In the example of 3 is such a state is reached when the CAD motion object PART RT to the CAD motion object SENSOR AREA RS2 on the right edge of 3 was promoted. Now, the input address of the PLC PLC is set so that the control program interrupts the activation of the CAD motion object DRIVE AREA RA2. This is implemented by the commissioning block in the geometry data such that the CAD motion object PART on the right edge of 3 stop.

At the The virtual commissioning process therefore reads the commissioning block VIBS cyclically with the aid of the CAD-ID the current geometry data of the CAD motion objects from the CAD drawing object and the current ones Output data from the PLC. The commissioning block VIBS calculates The PLC data of the CAD motion object of type Sensor new and writes the input information to the PLC, and calculates the PLC data of the CAD motion object new type of drive and moves it using the in the CAD drawing. Since the commissioning block VIBS cyclically reads the geometry data, also changes, the over the CAD system in the CAD drawing are performed manually in the VIBS data objects considered. If e.g. in the drawing with the mouse a PART about a Sensor area is moved, the input of the instrumentation object sensor in the corresponding VIBS data object switched accordingly.

According to a particularly advantageous and in the 1 already shown implementation of the invention, the commissioning module VIBS advantageously on three program layers E1-E2-E3. These are logically vertically superimposed and are referred to below as levels. In this case, only a vertical data exchange takes place through the program layers, ie only adjacent levels, ie E1 and E2 or E2 and E3, exchange data. A data exchange directly between the levels E1 and E3 is therefore not programmatically possible.

So, the first level represents E1, in 1 referred to as "PLC I / O data", a direct data interface to the programmable logic controller PLC. The second level E2, in 2 "Instrument objects, VIBS data objects", the actual data platform is used for the administration of all data necessary for the initialization and execution of the simulation, as described above, the level E2 also receives data via an interface S3 from the data platform DB third level E3, in 1 "CAD interface, geometry data", represents a direct data interface to the CAD application and CAD drawing. Thus, while the inner level E2 forms the data platform for the logical management of all objects that are to be accessible in a CAD drawing simulation the quasi-outer levels E1 and E3 are interface layers that effect data translation for the purpose of communicating with the PLC and communicating with the CAD application.

Advantageously, the communication between the plane E2 and the controller PLC via an intermediate interface ST, as in 1 already shown. In this case, the data connections 541, ie write data, and 542, ie read data, can either be pure software connections or a physical data bus, eg a so-called PROFIBUS or a data bus based on the "Industrial Ethernet" standard Resources of a non-existent asset are managed as abstract software assets for simulation purposes 1 dashed line illustrated technical system ANL, symbolically indicated therein "devices" and their process interfaces I / A are therefore usually not yet available.Their functionality is a so-called "commissioning" consisting of the commissioning block VIBS, the "animated" CAD drawing The elements VIBS, CAD and DB can advantageously be processed as program elements in a personal computer PC .. In another embodiment, not shown in the figures, the controller PLC in the data processing unit PC can also be emulated in software Trap would also be simulated the interface card ST software.

Will the virtual commissioning of ei If a user is started, the commissioning block starts the control. If the sensor is not damped, the output A328.0, for example, is set by the controller. This is in the example of 3 shown. The value of this output is read out by the commissioning block and interpreted in such a way that the roller conveyor R is to convey and represents this conveying process in the CAD drawing by simulating the real sequence of movements. The commissioning block can simulate this simulation realistically, since the drive speed of the drive is known. This has preferably been read as an attribute from the library for resource data of the data platform. Based on this data, the commissioning block can also determine that the part has now been conveyed during the course of the simulation in the CAD drawing to a point that corresponds to the position of the sensor area. In reality, the sensor would now be activated. To simulate this activation, the commissioning block sets input E95.0 in the controller. The controller reacts by resetting output A328.0. The commissioning block reads the current status of this output and responds by stopping the simulation of the conveying process. During the simulation, the current states of the CAD motion objects RT, RA2 and RS2 are recorded regularly. This is in 3 shown by the logical connections G3, G2 and G1.

In summary, the following steps are advantageously carried out during a virtual commissioning:

• 1. The commissioning block causes the PLC PLC to start the control program loaded in it,
• 2. The controller PLC causes its outputs to be set in response to the inputs,
• 3. The commissioning module records output values via level E1 and forwards them to level E2,
• 4. The commissioning module updates the level E3 via the level E2 as a function of the output values.
• 5. The commissioning block controls the CAD drawing via level E3, ie virtual commissioning takes place,

• 8. go back to step 2 and re-run the following steps.

The Invention allows it, a CAD drawing about a control PLC so to speak "with control" Commissioning blocks can e.g. binary inputs and outputs the control PLC are set, or the controller PLC takes over - after setting of appropriate starting conditions - fully automatic control. The controller works as if it were directly with real existing technical equipment connected in a real technical plant. The particular advantage of the invention is that neither the technical equipment still the technical equipment available have to be. Rather, you can through all states a corresponding plant previously in a by applying the inventive method animated CAD drawing to be tested. Thus it is possible the Put the system into virtual operation.
