• When dynamically created variables are emptied in the sequential process template?

  I have a sequence TestStand 2014 in which I dynamically create and fill many FileGlobal variables in the installation section of my main sequence.  I have it using the TestStand API to read the data in an Excel file (the data consists mainly of thresholds, limits, etc.).  The methodology itself works flawlessy.

  However, there are differences in behavior when using entry points both execution of the sequential process model.  When you use the entry point of execution 'Single Pass', he has no problem in test a DUT after another.  However, when you use the entry point for execution "Test DUT", I encounter the following error after completing of DUT1 and DUT2 testing:

  An error occurred the call 'InsertSubProperty' in 'PropertyObject' of 'NI TestStand 2014 API.

  The name of the element "VariableName" is not valid because it is already in use.

  I interpret this error message means that the variable I am trying to dynamically create the DUT2 track is already present race of DUT1.  I have a few questions about this:

  1. at what point in the sequential process template are dynamically created variables flushed, such as run a further by using 'Single Pass' starts with a clean slate?

  2. is there a reminder that I can substitute such as variables to rinse after each HAD run, allowing me to dynamically create variables on each HAD, during execution using "Test UUT?

  3. better yet, is there a counter of TestStand I can query to determine if I already ran DUT1 when using "Test DUT", such as DUT2 uses the variables that were created dynamically on trail of DUT1?

  Or you can simply use the PropertyExists function as a precondition.

• First JavaFX application with time sequential process

  Hi all

  I'm working on my first JavaFX application.  I have a user (view) UI elements in place, I have a controller that works properly (with the exception that I will mention below), and I have a model that works properly (processes data correctly), but the model code was written to run under a user interface.

  What I want to do is the following.  When the user clicks on the "Run" button, the user input is passed to the model via the controller and the data is processed.  It's a do - once a sort of thing where the input is transformed into the output and that's the end of it.  The user interface can be reset and new entry provided, and all this happens again by clicking the run button.  Here's the problem: the treatment has several steps that need to occur in order, but some may take some time.  I want to provide feedback via a message (what is done) and overall progress via a progress bar (the two items in the current user interface).  The problem is that I am still very confused on how to accomplish the user comments.

  The user interface was built in SceneBuilder, and I attributed to the onMouseClicked event to call the runButtonClicked() method in the controller.

  The runButtonClicked() method calls the private methods that run the processing steps (I'll do something more intelligent exception - please ignore that for now)...

  public void runButtonClicked() {}

  runButton.setDisable (true);

  sdfFileBrowseButton.setDisable (true);

  outputFileBrowseButton.setDisable (true);

  try {}

  prepareSDFFile();

  prepareModels();

  collectDescriptors();

  makeSamples();

  evaluateSamples();

  writeResultsToTextFile (results, outputFile);

  } catch (IOException exception) {}

  System.out.println ("Caught an IOException:" + exception.getMessage ());

  } catch (JAXBException exception) {}

  System.out.println ("caught JAXBException:" + exception.getMessage ());

  }

  }

  Each of the calls in try-catch are tasks that need to be linked in the order listed.  Some of them may take a long time (for example, collectDescriptors(), evaluateSamples(), and writeResultsToTextFile().  The work is not done in the controller.  The controller creates instances of classes that do the actual work (this seems to be a departure from most of the tutorials I've seen - it seems the model and the controller are mixed in the tutorials).

  I would like to alert the user about this step is execution (by means of a message in the user interface) and at what stage of the process as a whole is in (through a progress bar).  It would be nice if the progress bar might reflect the status of each individual step (back to 0 at the beginning of the next step), but given the bar just reflect more all the advances (e.g., how many six steps were finished) would be sufficient.

  I also want to be able to manage a Cancel key event and just stop the whole process and reset the app (lose whatever work has been done is OK).

  -I can truly say what should be the best approach.  None of the examples in several tutorials, I went on that have really touched on this type of sequential process.  I would like suggestions.

  Thank you

  
  Dave.

  
  

  Suggested approach

  What you describe is a quite classic case to use the utility javafx.concurrent (task and Service).

  Your application is a perfect fit for the use of these services, which will provide you with:

  1. an execution thread concurrent to run your journal of the current process

  2. a feedback mechanism of thread-safe for the progress that you can link to a ProgressBar for interactive progress feedback.

  3. a feedback mechanism of thread-safe for messages that you can bind a label to your interactive status feedback.

  4 code example that illustrates the ability to cancel and restart the process.

  5, a setter callback method of success that can be configured to provide a result and decide on the success.

  6. a reminder Set accessor method failure which can be set to make an exception and to take measures in case of failure.

  Task and Service samples

  There are a lot of examples of tasks if you search for task of JavaFX.

  There are also great documentation in the javadoc task and Service .

  Here is an example of using a service of JavaFX.  The example is a bit old and uses does not use some new features of the API such as setOnSucceeded or setOnFailed, it also uses models of generator now frowned upon, however, the bulk of it is still relevant to what you want.

  Here is another sample more complicated to make 300 cards off screen and save the files in JavaFX, although I doubt that your task should be as complicated and probably a unique control service is all you need, in order to not pay too much attention to the more complicated example unless you need this kind of functionality.

  Here's another simple example for Re: create several parallel tasks into a single service, which shows in fact sequential and a side event of the stage of the tasks within a service.

  Progress can be reset between the steps, so that the message indicates the current step and progress indicates the status of the market rather than overall progress.  You can expose different processes for feeding of the overall progress back in addition to the progress of the step.

• News station using the batch process model

  Hello

  I have a test sequence using a model of sequential processes and station information by using the following, I.

• Implementation of the synchronization steps without using batch or parallel processing sequences

  We use a model of customized integrated process based on sequential process model.

  I have to call the Synchronization Manager in order to use the steps of synchronization when you do not use batch or models of parallel process?

  All operations (locks, Rendezvous, Notifications, queues, etc.) and the steps of synchronization works in any model or a model, with the exception of the synchronization of the lot.

  If you need batch synchronization, your model must use synchronization > advanced > step type specification of batch processing to specify what threads are in the batch. Since you are not from the model of batch processing, I doubt that you have to worry about this.

• Process vs asynchronous sequence in parallel model

  I've been studying the TestStand features and learn how to use it for about a month, so still very new for the environment (although I have been using Labview and Veristand quite strongly for about a year).  I wanted to get some clarification on the use of different process models, because I think I can be lack of understanding of certain terms.

  Here's a little history of my project:

  I have a Labview VI that I created to interface with a remote target (emulator).  Previously, I used the VI to run the tests manually, and I would like to use it as a code module in TestStand so that I can run automated tests.  I intend to use the same VI several times throughout the test sequence.  The functionality of the system is dependent on maintaining constant communication with the emulator, so I can't be opening and closure of the code module several times.  Once opened, it should stay open and communicate continuously (I hope I won't have to create modules of code to be through with my current VI 'wrapper').  Break the communication would result in most of the results of the tests to become invalid.  For these reasons, I chose to call the VI as a module of code into a sequence of void so that it can be run asynchronously, outside the main sequence.

  Now, as I learn more about the details of TestStand, I introduced the notion of "process models.  I was initially using the default sequential process template, but I would like to know if I should come parallel process model.  From what I can tell, the parallel process model is used when multiple Test DUT tests or running in parallel.  Is this correct?  To clarify my situation, I'll test only 1 USE, I use only 1 code module and I run several test with this module of 1 code steps.  I continually have to pass data back and forth with the code module as it runs parallel to the main sequence and there are probably several sequences of void called during the process, so that I can maintain the modularity with my tests.

  So the question is, can I take the parallel process model, or should I continue with the sequential process model and asynchronous sequence for my code module run in parallel?  Thank you very much.

  GSinMN

  I would definitely recommend using the sequential model with a sequence of asynchronous way running for the special code module, in this case. Let us know if you have any other questions on how to architect the system! It is certainly a good idea to plan these kinds of things before we get too deep in development.

• complete a report and start the following in a sequence

  Hello world

  because I did nothing in the model sequential and other models an options so far, I do not know how to start. Maybe you can help me with the following problem:

  I have a lot teststeps in about 50 sequences. The problem is, that my report is too long to be displayed with the internet explore (I choose the ATML format).  I spend most of the sequences manually and restart the test until I have tested everything. It's too much manual work.

  Now, I want to automatically create a new report, for example 100 teststeps, or on another event.

  A problem may be the style sheet, because the sequences are not finished when the report was created.

  Another problem is how to tell teststand that he must finish the first report and start another.

  Thanks for your response

  Meike

  Meike,

  Another option, though less frequently used, would be to Pierce your sequence of subsequences and have some (or all) of these subsequences to run in the execution of a new one with the sequential process model. This will cause several smaller reports to generate. This approach is described in point 4 of this white paper: http://www.ni.com/white-paper/14394/en/

  This approach seems like it might be what you are looking for. Let us know if you have other questions about this!

• Test bench - selection of material resources

  Hi all

  I use TestStand 4.2.1 with LabVIEW adapter (LV 2009).

  I'm developing a test sequence which, for the time being, works on the sequential process model and will run later on the model of parallel processes. I also develop OI in LabVIEW for this test sequence. The test involves the use of an EMS and a NISE virtual device (I preferred, so far, using subVIs NISE in LabVIEW modules rather than integrated NISE TestStand facilities).

  (1) in order to select the resources of hardware device (EMS reference, name of virtual device NISE, NISE itineraries to be connected, etc.), I have a dedicated module for LabVIEW (VI) who runs first, in the configuration section. It is followed by other modules of "Open & configure ' for each material resource, it is a basic interface (dialogue) with drop-down lists that allow the user to select resources. However, if I want to use the parallel model for 4 DUT, it will display 4 these dialog boxes; also, in each race for each object to be measured, re-displays the dialog box.

  My question is: How can I switch handles/references to material to be configured for the IO sequence I'm building in LabVIEW? Should they be passed as parameters to sequence (params) for MainSequence? The operator must select resources only once, when he starts the IO; After that everything should work without needing to select again the device resources.

  (2) if I implement the model of parallel processes, how can I access variables of each socket (running in parallel to the test sequence), etc. At this point, I do this by using the 'testbed - Get property"Subvi (from the context of the sequence and the search string to the Subvi). In the case where I have 4 outlets running, how to sequence of each socket context? Or is there another way to access the properties? (I see "ThisContext.RunState.TestSockets" as variables in TestStand... is it a clue?)

  Thank you in advance for your help!

• How to set the path of the report in a plugin for model

  I'm trying to figure out how to set the path of the report in a plugin process model. I can't find a way to have access to it. It seems this would be a reasonable thing to do since the plug-ins are for the treatment of the results. Does anyone know how to do this? We generally use the sequential process model, but I try to keep my plug-in as independent as possible.

  Thank you.

  If I understand correctly, you want your plug-in, when enabled, change the settings of all other instances of the report OR plugin as their reports share the same directory that your plug-in is configured to use.

  If so, your plug-in can access and change the settings of all other instances of plugin. All instances are passed to all the points of plugin entries in the subproperty of the plugins of the ModelConfiguration parameter table. You can browse this table. Any element of the array with an equal to "NI_ReportGenerator.seq" Base.SequenceFilename is an instance of the report OR plugin. Its report options are stored in the element under PluginSpecific.Options.

  You can change the report options to what you want. Note that the recall of the ReportOptions model is called from template-plugin Initialize entry point, then you might want to ensure that your changes are applied after that, so they are not replaced. To do this, you could make your changes in the Initialize entry point of your plugin and make sure your plugin runs last. To rotate the last, you can set the FileGlobals.ModelPluginComponentDescription.Default.Base.RunOrder in your file of plug-in with a value greater than 0, for example 1.0 (see Help for TestStand > Fundamentals > process template Architecture > plug-in for the model process Architecture > Structure of the plugin sequence files > plugin model of entry Points > Order Execution of Point of entry at run time).

• Can I change the name of the object to measure report

  Hi, I'm new to TS! Can I change the name of the object to measure report? Who can help me. Thanks in advance!

  «Under normal circumstances, I finished the test USE, TS generated the report like this "report [13-29-06] [4F492CAB04] [2012-11-28] .html'.»

  Can I change something, when TS report will like this"report [13-29] [4F492CAB04] [2012-11-28] .html' without seconds!

  One way is to modify the process template.

  Locals.ReportFilePath saves the name of the report. You can access only functions (such as SerachAndReplace) to create the new ReportFilePath.

  In the model sequential process step determine the path of the report file provides the path to the report file using the report options settings. Custom code can be placed after this step.

• Perform a sequence using the new method of execution

  Hi ppl,

  I use the Engine.NewExecution method in LabVIEW to perform a sequence using sequential process model. I have been successful in this attempt.

  Now when I tried to pass arguments to the sequence with this method I could not do

  From the help file, I found to pass property to the sequenceArgsParam in the Engine.NewExecution. I used the Engine.NewPropertyObject to create a new property object. My problem started here. I was not able to define the parameters for the property object I created. When I created an object of type container property, newExecuion method returned an error indicating that the type is the string even if the setting for my sequence was a container. When I created a method of setValString string property object returned error saying unable to find settings where the look of string upward was parameters.x

  Please help me some body. I'm stuck with this upward.  can someone give me an example of program that passes parameters to the sequence when running via the NewExecution method.

  Hello

  It is not the Engine.NewPropertyObject method to pass parameters

  I used to sequence method before running the sequence

  try to replace the step Engine.NewExecution of this VI

  the values are in a cluster table: parameter is the name of the parameter in your sequence, the value is the value to pass

  A2

  Note 1: there is only the string in this VI, it is possible to change with integer...

  Note 2: If you have a container, the parameter name is "container". "" The name of the parameter.

• Several cameras for machine vision

  We would like to use Vision Builder I do Visual inspection of our products. Due to the large size of the object, we might need several cameras

  to do this. Is it possible to use information from several cameras to Vision Builder or do I have to use several constructors of Vision at the same time? Are there

  other solutions?

  Kind regard

  Bert

  Certainly, Vision Builder AI can handle the acquisition of several cameras. If you trigger the cameras, the software can process even the images that have been acquired at the same time (although sequential processing steps, the step of acquiring image can be synchronized with other CQI steps if necessary for your application).

  The software includes templates to illustrate several different architectures of camera (see the new Template Inspection option under the new Inspection during the creation of a new inspection of the splash screen), and here are a few documents area dev that may also be useful:

• Parallel recovery in RMAN?

  O.S: OEL 5.5

  DB version: 11.2.0.3

  Hello Experts,

  I have some doubts on the recovery RMAN. I would like to know your opinion of experts.

  (1) process that performs the RMAN recovery (just as the MRP in standby).

  (2) I always thought that recovery is a sequential task. This thread (parallel recovery) saved my theory. However, I see RMAN commands likeRMAN>recover database parallel 4 . So what is the parallel option used for?

  (3) if the recovery is a sequential process, how can we have several MRP process on the side of Eve (PHYSICS: why recovery managed to reproduce so many slaves?) (Doc ID 885872.1).

  Thank you very much in advance.

  Satya

  (1) so the "server process" began with the RMAN dealing with recovery too? Please correct me.

  RMAN Utility is just a customer.

  RMAN connect to the database and execute commands, all the work is done on the server side. Server database always process take care of backup/restore/recovery.

  (2) automatic channels is also used for the recovery and restoration? I always manually assign during the restore and recovery.

  N ° auto-channel is reserved for backup and restore operations.

  RECOVERY operation (aka Media Recovery) is different from the command RECOVER, because the execution process of recovery RECOVER command also trigger archivelogs of RESTORATION, and RECOVERY process apply that Redo on data files.

  Recovery operation is managed by * parallel * parameters not automatic channels.

  (3)'with the resumption of parallel media, these blocks of data are subsequently distributed evenly to all recovery processes to read into the buffer cache. "--> Does this mean that the recovery of the parallel media is intended to copy multiple blocks in parallel to the memory buffer uses cache ONLY. However, the recovery process (applying the vectors of change) is a sequential process? Please correct me

  The writing is not all sequential process, but each block of data is retrieved sequentially.

  Parallel media recovery, the database uses a 'division of labour' approach to allocate different processes at different data blocks while rolling forward, which makes the process more effective.
