Structure of cases only the execution of a case

(Again), I'm trying to control steps ThorLab, LTS300 and MTS50-Z8. I wrote the attached program for this. The program essentially starts communication with stadiums, made a few moves with them, then disconnects them. I have asked me to include a button 'CANCEL' or 'STOP IMMEDIATELY', just in case where something goes wrong with the stages, that termiantes of the communication with the stages immediately. Stop key immediately in the vi below done stop the program when you press on, however, I was expecting the program to run the routine of movement when the button has not yet been activated. But nothing happens. Could someone explain to me where I'm wrong. I've also included images of the case of true/false for the button and the sous-schemas that should trigger the button. I'm afraid that it is very simple...
Thanks in advance

Makes no sense to me!

Rules of data flow:

1. no code can run until it has all its entries

2. no code will display anything up is finished running

3. a loop cannot go through all that she has not completed running

So what happens is you have an addiction to data between the loop and the structure of the case.  The structure of the case cannot run until it has an entry in the loop.  But the loop will not release its value up is finished running.  And the only way to stop this loop (and authorize his release must be sent) when the termination of the loop is set to TRUE.

  • Only one execution at the time the application

    What I'm trying to accomplish: that only cover the execution of the application can run simultaneously.

    Is there a setting of TestStand I'm not find which would allow this?

    As a solution, I do something along the lines of aging on execution buttons in the IO at the beginning of the process template and allow them to the end.

  • Can't manually type us the commands within the execution block?

    11.2.0.3/Linux

    I was doing a RMAN restore to a new server.

    Here's the code I wanted to run to restore
    run
     {
     SET NEWNAME FOR DATABASE TO '/fnup/hwrc/oradata/spikey';
     restore database  ;
     }
    Because it's just 2 lines in an execution block, so I thought to type manually. After typing the first line (SET NEW NAME..) that ends with a semi colon, I pressed the ENTER key so that the following line, and then type the RESTORE command. But I got the following error message.

    The VALUE of NEWNAME should be included in the execution block. In your case, you must divide the NEWNAME the NEW NAMEkeyword.

    new name for the database to ' / UNPF/Edda/oradata/spikey. "

    You must use the command in the execution below block

    the value of newname for database to "/ UNPF/Edda/oradata/spikey."

  • Restrictions on the execution of methods in a package

    Hello

    I have a question. Is it possible to restrict users in the execution of methods in a single case.


    For example:


    In the package below one Admin should have privilege to perform all of the methods in sample_pkg. Other users must have administrative privileges to run only the Get_Details function.

    Please let me know how I can implement this scenario in Oracle.
    CREATE OR REPLACE PACKGAE sample_pkg
    IS
    
       FUNCTION Get_Details;
    
       PROCEDURE New_Order;

  • Any possibility using only the built-in GPU?

    Mac OS X 10.11.6

    I wonder if it is possible to use only the GPU integrated while playing games. Cause I discovered that some games are no need to use the AMD GPU, but it is automatically switched to the dedicated GPU and drains the battery.

    Hope there is a solution for this problem. Thank you!

    It is somehow a conditional scenario suggested in this article

    {These links seem to show older versions of material your model}.

    Don't know if there is a way hidden within the system to change the default to

    In any case...

    Good luck in this case!

  • return only the decimal value

    What function can I use to return only the decimal value of a formula

    (97 * 2.2) / 14 value returns 15.24

    I only want to use le.24

    Salvation is

    Use the formula - INT (formula)

    In the special case above:

    =(97*2.2)/14 - INT ((97*2.2)/14)

    You see two places to the right of the decimal separator in reason to be rounded off to the value real, in the shape of the cell to only show as two decimal places, either by setting the width of the cell close enough to force the rounding of the displayed value.

    Note that if the result is rounded (using the ROUND function) the actual value of the cell will be the rounded value. For the other two cases, the value displayed indicates only two decimal places, but the real value in the cell (and the additional calculations used by referring to this cell) is 0.242857142857144, which could lead to surprises in the results of the calculations downstream.

  • Please help - I don't understand this: because iPad can contain only the content of five Apple ID.

    I give my son my iPad.

    I try to download Apps on it and I get the message: some of the files in the iTunes Store iTunes library were not copied to the iPad because iPad can contain only the content of five Apple ID.

    As far as I know there are only 2 Apple ID involved - my own and the one we did for him as a minor.

    If someone has had this problem and can you help me to overcome.

    It is typical that this situation happens the day before her birthday - I wanted to give him tomorrow all loaded with his own stuff. It five of its apps accepted last month when I first came with the idea and now...

    Anyone?

    This means what it means: iTunes Store items are tagged with the Apple that was used to buy ID. Apparently in this case, for some reason, over 5 ID are involved. Which could include accounts that are no longer used.

    In general, it is best to follow these steps before giving your iPad to someone else: what to do before you sell or give away your iPhone, iPad or iPod touch - Apple Support

  • How to shorten the execution time of the NXT (TETRIX & MATRIX toolkit) brick

    Hello

    How to shorten the execution time of the NXT brick?

    (TETRIX & MATRIX toolkit, running time)

    The software is 2012 LabVIEW for LEGO MINDSTORMS

    Thank you.

    Hi 40123157,

    You use the module in an appropriate manner, and there is no simple way to improve the time of loop iteration beyond what you've done. Here are my suggestions:

    (1) the i2c commands take a long time. In your application, it may speed up if you run only move the engine only when the engine speed has changed.

    (2) for this particular example, you do not use the release of the report engine. If this VI does not need to run it can be removed.

    (3) If you need to speed up execution other than that, as a user advanced LabVIEW, you can create a copy of the VI of engines to move and change it as you choose. All you have to to the "DC motors' entry is use cluster to array on the cluster, as shown below. I think you can speed it up by running all the settings before the loop (type sensor and fixed connection configuration), and removing the value of power if you send only the values between-100 and 100.

    (4) drawing on the screen can be slow you down here.

  • How can I retrieve the execution of TestStand 4.0 Test results in a c sharp Application?

    I am writing a c sharp application to launch a test sequence in TestStand 4.0.1 and then collect the results of the tests to update our own screens / report (s).  I'll need some sort of recursive routine to collect the following information (if available) for each stage: name, result, Min value, Max Value, measured value, units.

    My attempts have been to an event to end execution allows to collect data:

    void EndExecution (sender As object, EndExecutionEvent ev)
    {
    Results PropertyObject = ev.exec.ResultObject.GetPropertyObject ("ResultList", 0);

    int numContainers = Results.GetNumElements ();

    for (int i = 0; i)< numcontainers;="">
    {
    PropertyObject resultData = results. GetPropertyObjectByOffset (i, 0);
    String testResult = resultData.GetValString ("Status", 0). ToString();

    PropertyObject testStep = resultData.GetPropertyObject ("TS", 0);
    Dim testName = testStep.GetValString ("StepName", 0). ToString();

    MessageBox.Show (i.ToString () + "". "") testName + "=" + testResult);
    }
    }

    But this only gives me MainSequence data.

    How to cross the ResultsList tree to access the results of all the test steps?

    tlaford,

    There are a couple of big problems with what you are doing:

    (1) it is best to call the code from a test report of the result of your sequence treatment reminder (just use an action step) or change the process template to call your code rather than to call for EndExecutionEventHandler of the user interface, because if you use Test DUT and then there is a separate resultlist by USE not by execution, and it is generally processed at the end of each use not at the end of execution. If you use the EndExecutionEventHandler then you should NOT use the process templates provided with TestStand because they don't work that way. Instead, you just run your sequences without a process template. Although I really recommend the path of process model, even if you write your own a custom, because it is more flexible, and then hardcode your treatment result in the user interface as you do. A few reasons why a process model is that more flexible or better are that it will work in any user interface, including the sequence editor (no changes to the user interface is needed), and it can do everything you can do in a sequence, for example to call a code module in any language supported , asynchronous sequences, call sous-séquences, etc.

    2 recursion) through each property at such a low level is bad because the names of the properties are not guaranteed to be unique for what you expect them to be. Anyone can write their own types step custom with some result properties that they would like. You must make sure that the full path to the properties is what you expect it, and you can even check that the type of step is one you expect. You should rather loop through the result of higher level items ONLY and are looking for the complete data lookupstrings that you expect from these elements. For example, instead of WalkTree you might have the following instead:

    This must be called from a step in a test recall report or in a custom process template
    rather than from EndExecutionEventHandler of the user interface, because if you use Test DUT then
    There is a separate resultlist by USE, not by execution, and it is usually processed
    at the end of each use not at the end of execution.
    Sub ProcessResultList (PropertyObject resultList)
    {
    numElements int = resultList.GetNumElements ();
    < numelements;="">
    {
    Element PropertyObject = resultList.GetPropertyObjectByOffset (i, 0);
    String stepTypeName = string. Empty;

    If (point. There are ("TS. ((StepType', 0))
    stepTypeName = GetValString ("TS. (StepType", 0);

    If (stepTypeName is "NumericLimitTest")
    {
    If (point. Exists ("Limits.High", 0))
    {
    Double highLimit = item. GetValNumber ("Limits.High", 0);
    Do something with the value
    }
    }

    NOTE: The two step type SequenceCall and NI_Wait can have subresults like that. A stage of waiting waiting on an asynchronous thread or the execution will have this.
    If (point. There are ("TS. ((SequenceCall.ResultList', 0))
    {
    Recurse for results call sequence.
    PropertyObject sequenceCallResultList = item. GetPropertyObject ("TS. (SequenceCall.ResultList', 0);
    ProcessResultList (sequenceCallResultList);
    }
    }
    }

    Hope this helps to clear things up,

  • Pause the execution of a Vi

    Hello

    I'm making an aplication with two main Vi. The first Vi is responsible for the configuration of different instruments. On the other hand, the second Vi is responsible for the different measures of an electronic circuit.

    My problem is that I want to pause the first Vi when configurations were carried out then go to the second Vi and carry out measures. When the measurements were made, execution must return to the first Vi and continues from the point where the program has been suspended.

    I am trying to solve this problem with the queues and some time a loop to stay the execution, but it does not work properly.

    The following picture, I have attached the while loop. This loop communicates with the Vi second to check whether or not the measures are completed. But it is not working properly and I don't know why. My question is: this method is good to solve this problem or there is another method better than this? Or quite simply, the break of a Vi enforcement cannot be done.

    Any help is appreciated.

    Thank you.

    Luisi says:

    Thank you very much, your answers are very useful for me. I understand that the state machine is the best method to carry out the proposed work. But I have a problem, if I decided to do it in two different VI is for space issues. I think that I can't do that in one Vi. Is it possible to have two sides of a same Vi?

    I will attach two pictures of front panels of the screws so that you can understand my problem.

    In this first image, I have attached the face before of the Vi that supports the configuration of instruments. The table is the values of the configurations, and each line is an iteration. As you can see the number of lines can be configured (sorry is in Spanish in the picture), which means that the space can be bigger than that.

    As you can see, I need two different screws to make this automazation. I've read tutorials on the state machine and I also looked at the model that is very useful and understandable. However, I don't see that this method can be used in a communication between two different screws. Certainly, I'm very confused and now I don't know that I have to do.

    Sorry because the first question is how to pause the execution of a program (idle state) and now I'm adding these issues and the need for the two different voluntary initiatives.

    Thank you for your attention! If you have an idea, I will be very happy that you help me.

    There are several solutions for this. If you have a main executable (state machine), it may appear in the settings (your first picture) window and sends the settings as an output (or make adjustments to the main state machine and hide while the other is running). The main VI appears the window of measurement that uses the input parameters. Once the measurement is done, you save the file and return to the settings.

    As a note, you will probably need a lot more than 3 VI, to get a good program structured and modular, I'm guessing 50, fortunately it's simple to do.

  • VI does not work properly when run at each full speed or highlight the run mode, but running at full speed after the starting and stopping of the execution mode games

    Start labview, so fix that will probably teach me a lot. Looked and saw a lot of posts of things only work in games of the run mode, but nothing like this. I have attached the relevant real-time and FPGA VI.

    The code is supposed to read a motor encoder. When ran regularly, it works somehow. It will update the counter of how sporadic all few seconds a fraction of a second. When ran in climax run mode, it appears really up-to-date. After that matches the execution mode is canceled, it works perfectly. Can someone find out what could be the problem?

    Ended up staring at me. I am sure that the problem was that if there is only one element in the FIFO when it checks first, it eliminates the two elements when the FIFO filled.

    Fixed it by adding a test for the number of items before and reading only if there are enough items to read. Attached file sets for reference.

    I have still no idea why he was running after delivery to highlight in the first place. We will never know. Bonus points for the answer = P

  • The execution of the sequence TestStand in LabVIEW via TS - API: execution different times for the same sequence

    Hello - the members of the Forum.

    I have a problem about the execution of a TestStand sequence into LabVIEW. I created a VI that offers the possibility to choose a sequence TestStand-file and then executes the sequence using the TestStand API. The implementation is based on an example in C++-Application found the following link:

    http://forums.NI.com/T5/NI-TestStand/unreleased-references-using-engine-API-in-C/m-p/2927314#M46034

    The app works pretty solid where the VI is executed the first time. The VI treats the sequence chosen in an acceptable time.

    But where execution is started again, the sequence takes approx. 30 sec more than in the first case.

    So far I have not found a solution and hope someones got a clue about this problem...

    I use 2013 LabVIEW and TestStand 2013.

    I enclose my own VI, a sequence of the specimen with a small sample of VI, so you can reproduce the problem.

    Kind regards
