• skip the steps programmatically

  Hello
  I want a pop up dialog box in my sequence and have the user select what they want to run, a labview graphical interface.  Is there an available teststand property to set to set programmatically a step to 'jump' once the race started?  I could do this differently by a prior or such a condition, but that gets a little hairy and I want to do as clean as possible.

  Thank you

  David J.

  You can use interactive executions instead of normal operations. See using the API for InteractiveArgs for more details. Another possibility is dynamically defining the runmode on the steps by using Step.SetRunModeEx () (you can pass an execution in this case to make the runmode change apply only to execution, rather than being a step editing tool).

  Hope this helps,

• How to determine the number of rows in the database and save the result to a local variable?

  Hello

  I'm a newbie in the use of TestStand, databases and SQL, and now I've met difficulties. I use TestStand 2014 (32 bit).

  I have a need to know the number of rows in a database and save that number in a local variable. I tried to practice using the database of the Types of step provided with TS. I tried to use the following in a SQL statement:

  Locals.NumberOfRows = ("SELECT COUNT (*) FROM TEST_TABLE")

  It returns an error: specified value is not the expected type. My goal is possible in this way, or I'm doing this completely wrong?

  -RautSa

  Thank you for your response, Norbert. I have a database of who wins new values at random, and sometimes I need the exact number of rows in this table.

  I managed to achieve my goal by using the SQL statement: "SELECT COUNT (*) as Rowcount OF TEST_TABLE", followed by a data GET operation, which records that number of lines in a local variable.

• structure of the event with a local variable

  Hello world... I tried to make a simple program with the structure of the event in Labview.
  I need to show a value in a table, when an external signal changes its value. (I read a lot of discussions and many documents and I don't understand the thing... Sorry)
  I want to say that I am getting a value of temperature of a sensor in a controller, it works in asynchronous mode sensor, so that the detector Gets a new value in different sampling rate.
  So the PLC program changes the State of a Boolean variable simple that in Labview, indicates that there is new data (newdatareceived---> 1,0,1,0,1,0...)
  I need this draw Labview (valuereceived) value in a chart when this variable (newdatarecived) changes.
  My problem is that the table always puts a value according to the cycle time in its loop and resumes the values... (I tried, with dynamic events and signage value... and I got the same result... It works fine).
  Thanks in advance.

  And the other way:

  

  Thanks for your time again.

  I've been doing a little test with xygraph and the example works now (thanks!) but I have a doubt, is this the right way or is there a better way?

  No, this code is meaningless. You write new (mostly the same!) points to the graph xy with each iteration (actually at twice the speed at which data can actually happen: 100 ms vs 200ms!), tax system unecessarily and more internal data structures like crazy.

  All you need is a simple loop with a single structure of matter which is true if the Boolean value is different from the previous iteration. Currently, you must add a point (the time for X, the value in Y) to the xy graph. Here is a quick sketch. (You can either use the meter or the elapsed time for X, according to your needs, so change if necessary).

  Events are mainly for the interaction with the user in order to avoid the loop turn unless necessary. Here you are already running a loop to interrogate the instrument and you can easily have the graphic way the same loop. Right?

  You should also be aware that the execution order is determined by the flow of data and not in a horizontal position. If it's important that OCX nodes running first in an iteration, you create a dependency of data (for example with the wire of the error). Horizontal compensation has no effect. The structure of sequence on the left has also does no work, then why is it there?

• Initialization of a local Variable (variable uninitialized perhaps, but it is initialized?)

  I have behaviors very weird with my code. Some error messages complaining about reference uninitialized variables has led me to search around and found out that the shareware I use has very little initialization of local variables. CVI gives warning of the compiler on these variables, and I don't think he has caught even near each other. I went through the whole file and initialized everything myself.

  Even after that I booted my variables, however, the compiler always indicates they are unitialized, and my code still does not work. I've attached a screen of warnings from the compiler as well as one of the problem functions. Note that in the first warning (36, 9 WARNING: variable '(*tw1).i' maybe is not initialized when used here) there two notes under it, the one who told me where the variable is declared and who says "1, 1 Note: Add initialization to silence this warning. When I double-click on that note, he points to the top of the file, as if he says me to initialize the variable outside the function.

  I also found a very similar post about this but the user has said they were defining the structure twice.

  http://forums.NI.com/T5/LabWindows-CVI/local-array-initializations-not-recognized/m-p/2638119/highli...

  In addition, I understand that the screenshot I've not yet initialized the members of the struct, which I intend to do once that I get rid of these warnings.

  What should I do to remove this error? Any help is greatly appreciated, I've been messing around with this for too long. Thank you!

  emoser,

  I think that the strange warning is due to a bug in the analysis of the variables uninitialized in the compiler. The inaccurate diagnostic tests is issued at the line where you set a variable of local pointer to structure kiss_fft_cpx. It seems that the warning is caused during the pointer variable declaration is immediately followed by a local declaration of a structure of the same type:

  kiss_fft_cpx * tw1 = NULL;

  kiss_fft_cpx t;

  Basically, the incorrect diagnosis will happen:

  1. If a local pointer to a typedef struct variable is followed by a statement of the same variable type.
  2. If the second local variable declaration is not initialized.
  3. It doesn't matter if the pointer variable is initialized or not.

  The bug can come because the compiler can guess that the region of memory in the data segment continues from the pointer variable through the definition of the second variable, because they are of the same base type. A possible workaround in your case would be to go to the declaration of the variables of the same type (in your case, the declaration of the variable t) before the declaration of the pointer:

  kiss_fft_cpx t;

  kiss_fft_cpx * tw1 = NULL;

  Fortunately, this problem is fixed in the latest version of 2015 LabWindows/CVI.

  I hope this helps. I would like to know if the workaround works for you.

  Best regards!

• LabVIEW: Concerns with local Variables and the readability of the program

  Hello everyone. I was hired for the summer to work at my University to a new laboratory. All right, but I have some problems with my main VI. I am a new user of labview coming from a C++ background. I went through several iterations of adding features, fixing bugs and doing my readable program. Before the last "cleaning" my program was so big that I couldn't see it all at once on my screen. My goal was to solve this problem. My solution contained three parts: use a state machine show parts of my code at the same time, to remove the son as much as possible, and use structures element to position my code manually.

  I met since problems write other programs that brought me here, and I saw a series of messages condemning the new programmers for their use of local variables instead of cables. I do not know my use of structures element as fancy boxes I can exclude the automatic cleaning is also a terrible practice.

  After doing some more reasearch on the subject I see local variables to add the duplicate in memory entries and their suppression can significantly speed up execution time. I have a delay programmed in a part of my code, but the rest can run as fast as he can as far as I'm concerned.

  I have attached my main program. Looking at it I think I did a good job to make it readable. But I'm not a user expert labVIEW.

  How to balance (do not use local variables, these structures element, etc.) efficiency and readability. Before you make these changes, there was so many things and so many threads all over the place that I couldn't even tell what was going on, and even less my teacher. I really wish I could see my entire program without scrolling on this computer of the laboratory (resolution 1280 x 1024).

  Advice on how I can achieve the efficiency, simplicity and common readability would be greatly appreciated. I feel I've done the latter while sacrificing the first two. Ultimately the three should probably be equally important.

  Thank you.

  LabVIEW 2010

  

  As said altenbach, attach your event structures.  It should really be only need structure of an event, especially for a simple VI like that (I counted 3).  This is the second time I have recommended this today, but fetch JKI State Machine.  I use as the basis for most of my interfaces.

  Here's a way to manage the break with JKI.

  

  

  

• Is there a way to get refnum one control from a local variable or the wire?

  I'm looking for a way to get the refnum of the element of a façade of a local variable or the wire. Is this possible?

  Is there a way to accomplish the following?  (These are published images, this is currently impossible in LV)

  

  or maybe

  

  If this kind of thing is not possible, is there a reason for this? If there is no reason why it is impossible, I'll put it on the boards of the suggestion.

  Why do you need this?

  A thread is simply data. It is not associated with a control.

  Similarly, a local variable is a way to access the data in a control, for not interacting with the control itself.

  Is the control of the right-click and selecting Create > reference not good enough for you?

  You can write code to get the reference to the controls connected to the cable and the the control whose desired local variable, but I feel that this is not really what you want.

• Jump to the step by step idspecifie

  Hello

  I use SequenceFilePostStep reminder to check a mark of the LV operator interface variable value.

  I would use this function to jump to the mainsequence for the first stage of the 'hand' a group of anywhere from sequences running.

  My idea was to use the step of prior declaration (variable worth check) and the area of the Expression, I would use the ID of the step to return to the first level of the main group of the mainsequence.

  How can I do this?

  Thank you.

  Hi Doug,.

  Thanks for your reply.

  No, I'm not in the same sequence.

  I have more footage, but I want to check the value of the variable at any time (with the reminder).

  I would go to the main group of the Mainsequence.

  In the callback of SequenceFilePostStep, you can set the next step index and group stage of the sequence for which the callback was called using an expression as follows:

  RunState.Caller.StepGroup = StepGroup_Main,

  RunState.Caller.NextStepIndex = RunState.Caller.Sequence.GetStepIndex ("UniqueIdOrName", StepGroup_Main)

  Hope this helps,

• How can I get the changed data in a def type control containing an Xcontrol with a local variable

  Hello

  I did an Xcontrol and I inserted this control in a def type.

  When I want to change the data of the control with a local variable in a VI the VI change nothing. The change of the data is not complete

  How can I fix this problem?

  Thanks for your help

  Hello

  What is your version of LabVIEW? You have a simple example program that demonstrates this behavior?

  I found an other discussions related to your problems with Xcontrols:

  update of type defs Xcontrol faade

  No data change event generated for an XControl in a Type definition

• Comparative analysis of local Variable Transmission times

  Is it possible to compare the time of transmission of local variables?

  I ran some stuff simple reference before, but never something that would understand how long we had to to get a piece of data in a local variable.

  I have attached a simple program that sends information via a local variable, and there is obviously some lag which is visible, well, I'm running at least visible on the system. I know that this lag depends on the system, the program runs on so I would really like to find a way to test it on the PC we use here.

  Any ideas?

  No, they are not the devil as long as you are aware of their capabilities and their limitations.

  Regarding "some applications cannot always use queues or notifiers accomplish certain requirements", give me an application where you cannot use a queue or the declarant, and I bet you can.

  The problem with your 'reference', is that it's a bad test.  You do a visual aspect to two parallel while loops that have no synchronization between them.  If you used a wait until the next msec in both loops, you would see then better synchronization.  Download the file read out of the loop that could cause a random delay.

  And the biggest concern with local variables is "conditions of competition".  Search the forums to learn more about them.  You cannot control this piece of code is running in what order.  If you have two parallel two loop iterations, if the value is written to the local variable before or after that the local variable is read and written to the other indicator determines if a value new or old is used.  If it's an old value, it will be a new iteration of the loop at the bottom before it is updated.

  Search the forums for the terminals of variables local vs vs property nodes, and you will see that the local variables updated the order of milliseconds.  The only reason you see 'in the Kingdom of less than 250 ms' is because it is the rate of the iteration of the loop at the bottom.

• local variable and high Ribbon

  I copied a VI to control the DSA8200 Tek to manage the DSA8300. I guess that all controls remain the same.

  The new DSA8300.VI is attached. Why does show DSA8200 in the top Ribbon on the front panel?

  And when I search this VI "8200", I find a local variable called "DSA8200.vi". How to change that to "DSA8300.vi"?

  I am also attaching ScopeDialog.vi, because it is called by DSA8300.vi.

  Thank you.

  If you can shed some light on why it happened, I could learn something.

  A local variable is the name of the control on his face and that's all the information you need. If show you right-click on any variable local and it the label, the label will be the file name of the container VI. Since you have already changed the name of VI, it has already changed to DSA8300.vi. Since it is redundant information, there is no need to ever show him the label of a local variable.

  I have never shown a label of a local variable before, it was new to me too.

  Yes of course!

  This is better handled by the recall of SequenceFilePostStepRuntimeError:

  (1) StepResultCode (number) is added FileGlobals

  (2) add SequenceFilePostStepRuntimeError callback to your movie file

  (3) the next stage of the declaration adds the recall of SequenceFilePostStepRuntimeError :

  FileGlobals.StepErrorCode = Parameters.Step.Result.Error.Code

  Here is an overview of the sequence:

  

  I hope this helps.
