Description

The invention relates to a method and a system for automatic error reproduction by reproducing system behavior in an automation system (a producing plant).

In modern automation systems today, measurement data or control data is recorded to a large extent and used for the control of an automation system. Both in the detection or generation, as well as in the forwarding of the data can lead to errors in which e.g. erroneous data that results in process errors during automatic processing. When entering parameters or parameters manually, incorrect entries or typing errors can occur. All this can lead to various problems, from quality defects to production downtime. Damage often has already occurred, or it takes a long time for the source of the faulty data to be located.

Maintenance and commissioning work on automated systems often has to be carried out under high pressure of time (as quickly as possible) in order to minimize commissioning and maintenance times and the associated plant downtime with their costs. For this reason, protocols for reproducing errors that have occurred or for recording errors that occur are rarely and often not of the required quality.

If an error or problem occurs during the work, an attempt is made to find a way around the problem.

Reactions and also errors do not arise exclusively from the data communicated between an operating tool ("Engineer") and a component such as drive controller. Often, the entire system must be used for troubleshooting. So the actions that are triggered by the 'Engineer' tool must be considered when troubleshooting.

• - für jedes einzelne Datum in einem Datensatz werden Gültigkeitsbereiche, z.B. ein Intervall zwischen Minimal- und Maximalwert oder eine Menge erlaubter Werte, festgelegt;
• - sämtliche Werte, die außerhalb des erlaubten Gültigkeitsbereiches liegen, werden als ungültig gekennzeichnet.

Furthermore, today there is no established way to feed automatically recorded data into a system for testing purposes. By hand, the ever-growing amount of records is no longer controllable or verifiable. Therefore, today automatable methods for the search of faulty data sets are necessary. So far, an automatic control of data is usually carried out only as a limit control:

• - Validity ranges, eg an interval between minimum and maximum values or a set of permitted values, are defined for each individual date in a data record;
• - all values that are outside the permitted validity range are marked as invalid.

By the known method, therefore, not all error components, but only rough errors can be detected automatically, since the limits for the allowed values of data must be widely opened, so that all theoretically possible values are recognized as "not defective". All other errors, e.g. can be caused by swapping materials are not recognized.

DE 103 53 051 A1 (Siemens) shows the automation specialist an automation system that can work in real time and in a simulation. In the simulation, there 16 , a starting value is taken from the real producing plant, and operator actions are tested as to how an exchanged software element (there: module) or an exchanged component in the simulation would behave. If it behaves properly (better: desirable), the simulation can lead to the component being tested being used also in the real automation system (there: 2).

From the DE 196 51 334 A1 (Ericsson) is a set of equipment that includes an operating test for a phone system to be tested. The operating test must be carried out in the presence of the customer under test conditions which are later to be expected for the operating conditions to be expected during operation and must be reproduced as realistically as possible. For this purpose, statistical methods are used which work with test pattern generator and with test instructions, and these test programs may even contain additional instructions (there column 6 , from line 52 , and column 8th , from line 29 ). This comprehensive pamphlet can not be summed up any more quickly, so that we would like to refer the reader, who would like to know more about these known test methods in communication networks, to the entirety of this document.

The invention is therefore based on the object to provide a method with which automatically an error reproduction of all error components is made possible.

The invention solves this problem by providing an automatic reproduction of a system behavior as a method having the features of claim 1.
For the solution according to the invention (claim 1) is a fault location in the course of troubleshooting (reproducibility) and knowledge of the detailed constraints of an error event. For this purpose, all process variables, communication and operating actions are provided with a real-time stamp on the producing system (the real system) in which the error occurs. These stored and written data are fed to reproduce the misconduct of a reproducing environment to seek and eliminate the errors without affecting the producing equipment (claim 1).

The invention is based on the following consideration. An operator tool and communication driver provide means for logging and storing user actions and communication with automation system components.

For this purpose, the data exchanged between the components and the PC Tool is recorded in a communication log file. The same happens with the actions that the tool operator performs via the PC Tool.

The PC Tool corresponds to a running on a PC operating tool.

The actions of the user and the communication data are provided with a real-time stamp recorded (claim 1), so that the temporal relation between the individual events (communicated data and user actions) is retained and can be used for later considerations (claim 2).

At later times, these data can be used to verify and reproduce an error. For this purpose, the commands given by the operator during commissioning are read from the log file as a source and made available to the operating tool in the original time sequence (in the reproduction environment).

The response of the automation component to commands of the operating tool that have been answered by the component in the producing plant takes the reproduction environment from the communication log file, so that the operating tool can be supplied with the original communication data. This helps in a real adjustment of the environment in which the error has occurred during commissioning, with a precise analysis of the cause of the error. The producing plant is not involved. It is replaced by the reproduction environment as much as possible (claim 1).

This procedure frees the commissioning engineer from making elaborate protocols and can provide time-decoupled data by means of automatic generation of online protocols on automated systems for later error analysis, evaluation and / or simulation. This also makes it possible to automatically find and eliminate an error that has occurred.

In one variant, a process automatically reproduces the behavior of a producing plant. From this system automatically logged data are used. They were created in real time. The emergence is the appearance in the real time (real time), and after emergence is logged in this embodiment, which includes writing the files as log files. Before writing or writing to the log file (logging or logging in), the real-time stamp is also stored in order to also assign a time to the logged data. At least two log files will be created, which keep the logged data from the producing system stored. The saving involves non-volatile storage.

The logged data can also be stored in new logfiles for a different timeout or other attachment behavior. They are provided to reproduce the asset behavior of a replication environment. In this reproduction environment, an image (analogously: a mirror image as a minimum requirement) of the producing plant is working. The plant behavior in the reproduction environment corresponds - with timely transfer of the contents of the log files - that of the producing plant. However, the producing plant is no longer needed, the reproduction takes place without their participation, with the exception of the provision of provided with real-time stamped data in the at least two log files.

Mirror Image as a minimum requirement rewrites that more devices or functions may also be present in the replication environment, so only a "lower bound" on the presence of functionality. The components required for reproduction to this extent are "functionally mirrored" in the repro environment.

In particular, an error is reproduced in a system, and this happens in the reproducing environment. The error itself, however, has previously occurred in the producing plant, and this should not be used again to reproduce the error, but the resulting data and logged in the at least two log files are transferred to the reproducing environment, which after a feed for reproduction the mirror image of the producing ones Plant is and also loaded with real data and can expire.

Reflection as a minimum requirement also rewrites here that however more devices or functions may be present in the replication environment, e.g. a data manager as a feed unit of the data from the log files, according to which only a "lower limit" of the presence of functionality in the reproduction environment is described in relation to the producing plant.

The mirror-image training relates to at least one computer with operating system, an operating tool, a command handler and a communication driver, which can be named as BusServer. The storage (or loading) of the data stored in the two log files with real-time stamps into the reproduction environment takes place via a data management unit, which can also be designed so that it has a control device which only stores data of one or the other Loads log files into the replication environment to run for replication there.

This reproductive environment then behaves like the actual producing plant, for the data that was provided to it from the at least two logfiles.

The component from the producing plant is also functionally correspondingly contained in the reproduction environment. The use of the component of the producing plant for the reproduction of a plant behavior, in particular an error occurred is not necessary.

As data, which are logged, process variables of the real system of the producing plant can be used. Communication data and operating actions can be logged in a split manner on the log files, each time provided with a real-time stamp in the transmitted sense, ie an assignment of process variables, communication data or operator actions clearly defined in terms of time and correspondingly timed to the real process.

Further advantageous design features will be apparent from the respective dependent claims.

The described functional elements 1 to 11 the plant 100 , and at least two logfiles 6 . 7 , which is not a physical component, but a functional or logical component in RAM or on a hard disk or any other storage medium of the PC 1 can be, belong to the plant 100 , The attachment 100 is a manufacturing facility that can perform any type of processing, any kind of transportation or operation, or any other kind of working function. In the example is only one component 10 this attachment 100 shown, but there may be a lot more components of the system. This component is given the one marked motor 11 a drive controller that can control the machine in motor and / or regenerative mode. The regulation of this engine 11 the controller takes over with a program not shown here. He is from the operating tool 3 parameterized. Possible maintenance. It is also possible a commissioning work on the plant 100 is to be made.

The logfiles described 6 and 7 are used for storing (recording or logging data), wherein a distinction is made between a communication data log file 6 and an operator action log file 7 ,

In a reproducing environment 200 The following functional units are included. As far as they are provided with a "dash", they are mirror images of the previously produced plant 100 specified functional elements, such as the PC 1 the producing plant 100 and PC 1' the reproducing environment 200 ,

The arrows do not symbolize a permanent connection between real plant 100 and reproducing environment 200 but a port of log files 6,7, at least these two log files 6,7, in the Reproduzierungs environment 200 as log files 6 ' , 7 '. In this reproduction environment 200 become the provided log files 6 and 7 named as 6 'and 7';

• - from a control unit 13 via which it is controlled whether optionally only the operating actions, only the communication telegrams (communication data) or both are fed into the system to be examined;
• - from a clock 14 that makes a commander 15 receives a timing, which is the temporal feed of the data of the files 6 and or 7 into the system of environment 200 controls;

1 to 4 show in the embodiment, as with the help of the process described above, the defect image to be examined on a laboratory setup (the reproducing environment) readjusted (reproduced) is. The laboratory setup is a kind of mirror image of the producing plant 100 , Here, for example, the error or a malfunction of the producing plant 100 be readjusted and analyzed. But it can also generally the plant behavior of the producing plant 100 not specifically aimed at finding or analyzing an error, but rather at investigating an asset's behavior as such.

Reproducing for debugging or first reproducing the defect is a special case of reproducing a plant behavior without involvement of this plant in the investigation. In this case, from this system, which uses at least two log files 6,7, as explained in more detail below.

The system or method uses only the necessary components in the reproducing environment for behavioral replication 200 (as at least present). Loading the data from the at least two logfiles 7 ' , 6 'from the producing plant 100 into the reproduction environment 200 takes place, the reproducing environment 200 the necessary components of the producing plant 100 to have a corresponding behavior.

With the help of development tools 16 For example, error recovery may begin. For this purpose, starting from the observable error image, breakpoints are set in the source code to be examined. After that, the data management unit 12 parameterized and the error reproduction by starting the Reproduzierungs environment 200 began.

If an error occurs, then the debugger 17 stop at the previously defined breakpoint and detailed troubleshooting can be performed.

• - die Reproduzierungs-Umgebung 200 hat die Aufgabe, die protokollierten Daten der Logfiles dem Laboraufbau über die Schnittstellen, Bedientool Kommandoschleife und Busserver parametrierbar, in den geloggten Zeitverhältnissen zuzuführen. Dazu werden die Logfiles 6 und 7 eingelesen und die Zeitdifferenzen der dort enthaltenen Logdaten gebildet;
• - nach Start der Reproduktion durch einen Benutzer, welcher in diesem Fall in der Regel die Person ist, die mit der Fehlersuche und Fehlerbeseitigung beauftragt ist, speist die Daten-Manager-Unit 12 die Daten aus dem Logfile 6 und/oder Logfile 7 in den Busserver 8' bzw. den Befehlshandler 4' des Bedientools 3' in der zeitlichen Reihenfolge ein, in der die Daten bei ihrer Aufzeichnung erfasst wurden (protokolliert oder mitgeschrieben).

The data management unit 12 is parameterised with the following steps:

• - the reproduction environment 200 The task is to supply the logged data of the log files to the laboratory setup in the logged time relationships via the interfaces, operating tool command loop and bus server. These are the log files 6 and 7 read in and formed the time differences of the log data contained therein;
• - after the start of the reproduction by a user, which in this case is usually the person responsible for the troubleshooting and fault elimination, feeds the data manager unit 12 the data from the logfile 6 and / or logfile 7 in the bus server 8th' or the command handler 4 ' of the operating tool 3 ' in the chronological order in which the data was recorded (logged or written) as it was recorded.

In this way, the reproduction of the fault of the plant 100 clearly facilitated or, under certain circumstances, only automated.

• - Einspeisung der Bedienaktionen in den Befehlshandler 4' des Bedientools 3';
• - Einspeisung der Kommunikationsereignisse (Daten) aus dem Kommunikations-Logfile 6 als portiertes File 6';
• - Einspeisung von Client-Telegrammen in den Busserver 5 zur Weiterleitung an den Antriebsregler 10 (als Beispiel einer Komponente der Anlage 100);
• - Einspeisung von Server-Telegrammen in den Busserver 5 zur Weiterleitung an das Bedientool 3.

The data management unit 12 can be parameterized in the mode of operation. These possibilities are:

• - Feed the operating actions into the command handler 4 ' of the operating tool 3 ';
• - Infeed of the communication events (data) from the communication log file 6 as a ported file 6 ';
• - Infeed of client telegrams in the bus server 5 for forwarding to the drive controller 10 (as an example of a component of the plant 100 );
• - Infeed of server telegrams into the bus server 5 for forwarding to the operating tool 3 ,

The advantage of the example of the solution is the ability to collect necessary information for detailed troubleshooting at a later time using the software operating tool used for start-up or maintenance without incurring an additional burden on time or labor for the operator ,

Other advantages include the generation of test scenarios based on real applications, which can then run ("run") automatically (fed from the logfiles) over and over again.

The for the reproducing environment 200 provided data from the real application environment, here producing plant 100 called, happens from the normal timing and provided with a real-time stamp. The logged (produced and logged in the producing plant) data of different nature, the time stamp is given so that every record, in terms of a particular record, a real time is assigned. This real time is via the commander 15 with the clock 14 timely in the reproduction environment 200 fed, the log data of one or the other or both log files 6.7 via the control unit 13 into the reproduction environment 200 Loading.

From the 2 . 3 and 4 go the processes of the embodiment of the 1 out.

2 shows commissioning with some example information, and the automatic recording of data. As a component 10 the drive controller is provided in the example. The command log file is the communication data log file 6 , The bus server log file 7 corresponds to the operator action data log file.

The operating tool 3 expires with a command loop, and a user starts the recording process. The recording is automated.

After 3 becomes the reproduction environment 200 configured. Here the configuration is done by a user and is controlled by the data management unit 12 , After the control device 13 , or according to their configuration, the recorded (logged) data at least one, preferably both log files 6 . 7 , as previously explained, and into the reproducing environment 200 loaded. After it is at the two log files to the real-producing plant 100 out into the reproducing environment 200 ported logfiles, these are in 3 as log files 6 ' and 7 ' named.

The command handler 4 ' is out 1 visible, the operating tool 3 ' works after 1 in the reproducing environment 200 ,

Due to the assumed, mirror-image behavior, better as a reflection of the plant 100 named, since there is no inversion or inversion of functions, but a functionally comparable behavior, is also a component 10 ' in the reproduction environment 200 the 3 contain. It corresponds to the controller in the example 10 that's the engine 11 ' controls and regulates.

The 4 illustrates the error reproduction as an example of the analysis of a plant behavior, which is generally related to the processes of 2 and 3 can be justified. One obvious point is the setting of a breakpoint for the debugger environment 17 as they are based on the 1 (right in the picture in the reproduction environment 200 ) was explained. With 4 can with the debugger 17 , the emulator 18 , and optionally a bus analyzer 19 a software error is found, which is also identified as an "error" in the figure.

As detailed investigation is left below in 4 a corresponding process symbolically drawn.
