• Multiple instances of VI with uninitialized SHIFT registers?

  Is it possible to run easily several instances of a VI that uses a shift uninitialized register? Take the Pt means by Pt function, for example. If I want to permanently keep a medium of digital data 1, I just put the VI in a loop and run it. If I want to have 2 digital data, I just change the settings of the VI "Preallocated clone environment execution" to and copy the VI below. Now if I want to have 5 digital data, he begins to take a little bit of real estate on the block diagram. I can put it in a loop For with a business structure that changes with each iteration. It is easy to make these cases, simply duplicate the case '0 '. But, if I decided to add something to the '0' case or something is a tiny bit different in each case, it then becomes a real pain to do this way. Is there a better way to handle this?

  Edit: I realized that if something changes with each iteration, I must rethink my datatype or continue to use a box structure. But, if we solve the first problem where I don't have to transmit a change to the stop "0" in all other cases, that would be great!

  

  Thank you!

  Use the node of the call by reference when you open N VI references to your VI MeanPtByPt - each instance will then be a VI reference who will maintain it's own memory space.

  Something like this:

  

  With the help of the indicator 0 x 8 means that each reference VI coming out of the open reference has its own data space. To be honest, need you the indicator 0 x 40 at the place/as well - but I don't remember off the top of my head.

  For touch devices such as your 9860 and the 9850, you can do a battery pull, or download a software to perform the reset.

  QuickPull is one, there are others.

• LabVIEW 2010 local variable behavior

  HI -.

  I upgraded to LabVIEW 2010 of 2009SP1 and the attached sub that VI no longer works correctly.  It is a case of State machine structure that is called inside a loop.  I will put a Boolean variable true local, then on the next appeal when the case changes the variable has been reset to false. He has not done this in LV2009.

  Someone tell me immediately I have a race condition, but these local variables are not be written anywhere else, just in these separate cases.

  See the attached code, specifically, the local variable 'Activate' is to reset during the passage of the 'turn on' case for case "power."

  Anyone else seen elsewhere deliver, or can shed some light?

  I've corrected the VI by writing the value in each case, but this different behavior I wonder what are the other issues lurking in LV2010?

  Thank you

  This code looks more like a kind of a motor of Action that a state machine, but not quite.  It is called several times since a state machine, and he decides who will be the next State according to the entries.  Instead of using all local variables, I would use shift registers not initialized (Nothing cable on the left side).  They hold their value of one call to the other.  A case more will need to be added in this case.  An event of default without a name, which would set the initial values of all the shift registers.  Make the default case and does the same name.  It will be called first automatically because the shift register is not initialized, then the default value will be called.  Inside the default case, set all the shift fits to the desired values.  Next time the Subvi is called, these values will always be there.  As long as nothing is wired on the left side, everything is wired for the shift state register will be the next case called.

  See attached vi.  It's broken because I have this thread not to indicators.

• complete the loop and get data

  I need to acquire the acquisition values of data every x seconds. Waiting in the loop of data acquisition is defined so that the next N samples are acquired after x seconds. Pressing stop the loop of consumer DAQ stops after the sec x which is connected to the wait function.

  1. how to stop the inner loop immediately when you press a stop?

  I also write acquired samples after doing some calculations on the samples.

  1. plan of sample of the queue to file consumer loop. Is there any other recommendations such as drop loop is not without samples? How many data can an expectation of the queue?

  Thank you.

  sonotk,

  You've missed the point. Rather than having a 5000 milliseconds of wait, use an expectation of 100 ms and count the number of times that you have been waiting for 100 ms.  When the count reaches 50, sample and start the count again.

  The counter is just in the shift register containing an integer. Inside the while loop you have a box structure. Test the shift count register to see if it is 50. If set to True, use the real case of the structure of the case. Inside, it's all in your loop except waiting and the logic of the judgment. In the case of false, you add 1 to the shift register and wait 100 ms.

  Looking at your picture code once again, it seems that the shift with TempData and VoltData regsiters are not necessary because you never use the data previous iteration on the left side.

  Ranjeet,

  Make a simple VI with two loops and some expectations.  Run with execution highlighting market to see what is happening.  It is a good learning tool.

• Really delete table 2D lines?

  I want to use the deletion of the array function to remove undesirable lines of a 2D array.

  Is intended to remove any line whose value for a given column does not meet certain conditions.

  In my case, for a given row, if the value of column 1 is less than 2.5, I want to delete this line.

  Typical responses on this forum suggest select rows that do not respect my condition and their construction in a table (back). What I want is to work with my 2D array and remove lines that I don't want.

  I know exactly why my VI will not work, but I don't know how to fix it. See the attached VI.

  My VI will not work because the first time I remove a line from my original 2D table and use the registry change in the loop for to pass the array updated the to the next iteration, the index of the next line I want

  to remove door on the 2D of origin table and no table updated the. How can I update the index to reflect the table changed?

  Do not use the terminal i.  Keep the index value in a shift so register.  If you delete something, just to pass the current value through in order to start at the same point (since the line as now moved down to the current line).  If you do not delete the line, then add to the index and pass it in the registry to offset.

  That, or work in the opposite direction.  Start looking at the end of the table to the beginning, so use the length of the array (N) under the Terminal value of the iteration, then subtract a value.

• type of data repository more quick vi

  I inherited a large application LV that, in some cases runs VERY slowly. It is almost exclusively due to the transfer of data between the application and the database or between a few screws to access the data in the repository live. First time data are necessary, it is read from the data base (via ODBC) and stuck in a LV repository with an identification number associated with (i.e., it is a version stripped of a class of porridge). This repository was written to be as simple (and effective?) as possible and is essentially a reentrant vi with a shift uninitialized register which contains an array of clusters. You can create, delete, read and write data in the repository as a Variant. Some of the groups of data are quite large (> 100 controls) and may contain subgroups or tables of channels and telephone numbers (I know, I know...).

  There are about 10 different repositories running. Each folder can contain data for items up to 30. The repositories as a whole are available on 1000 times and the 200 times database for a given operation (which therefore ends up taking about 20 seconds!)

  Because I don't have the luxury of rewriting the entire application from scratch, I need ideas on how to speed things up. So: Is there a quicker way to store/retrieve data as the repository I described? Are the massive parallelism and a 8-core chip my only Savior?

  I am running LV 7.1 on XP. I have attached a JPEG of the repository.

  Thanks for any ideas

  
  

• How can I leave a 'comments' field in my table?

  Hello!

  I use a table in a very similar way as perscribed in this video tutorial: http://www.youtube.com/watch?v=RbDLJ1aaG3E

  My data comes from a coil that records the core data-sample magnetic ocean sediment. My project is almost done, but I have a major problem. My table (referred to as a control) has a "comments" column so that the tester can easily annotate readings. For him, I would like to be able to do this during the long test sequence, which occurs in a while loop. However, this column is unwired (only has an entry for the first four columns) and I think it's being crushed like a zero on each iteration of the loop. I can write in the comments column, but it disappears to the next loop. I write all my comments after the loop is finished, but I'm afraid it would be a waste of valuable time trial. Does anyone have any ideas? I am fairly new with all this, so please forgive me if Ive missed something obvious. Thanks to you all! You have been with me for almost a year thanks to this project, if you knew that or not.

  I didn't change the table you want to add to be an indicator.  I said replace the chart by an indicator.

  You still have a problem working with the table which is an indicator of the combination and control.

  I will try to encapsulate the table so that it works only on in the context of a driving force.  Store table data into a motor of Action/ functional global variable.  Use a structure of the event to detect when the user makes changes to the table.  Send the modification on the engine of the action and leave things to update in this shift uninitialized register.  Whenever something needs the data in the table, it uses the action 'read' the engine of the action.  Any time that something needs to update the table programmatically, he does that through action "update" action engine.   (This includes data that comes from the structure of event when the user tries to edit the table).

  I won't guarantee that it works perfectly.  But if it were me, it is what I would try first to ensure that you experience this issue of race condition to have an update of the user, control and the program up-to-date control randomly in a random order.

  I tried to fix some of the thing I was talking about in the previous post.  See the VI attached and use it.  Things like the addition of a 1 to a value can be made more easily by using the function increment (+ 1) of the digital palette.  When there are multiple and not the password, you can use the arithmetic node composed of combine Boolean logic.  Inputs and outputs are individually invertable.

• AEs/Single/data queues the value element references

  I'll have my CLD exam in December, and I'm just trying to 'inflate' as much as info that I can of course of the forum, alongside the preparation of the material...

  I also started to read "nuggets" pleasant and interesting too, and I hope I can get clarification for some of my issues that have emerged. (Sorry if I have a question is too noobish, trying to practice for the CLD beside my regular daily workload, and I am a little slow thinker in the night )

  I use often FGVs (and ActionEngines) in my applications, and for some "surfing and learning' on the discussion forum, OR I found this post:

  http://goo.GL/Cz1d0p

  People here recommended that the OP could use screws of wrapper which method has 2 benefits, explained here:

  "Wrap".

  http://goo.GL/J4vEIE

  My 1st question:

  I'm not really sure of what means a VI wrapper? Is this a Subvi, where the certain Subvi AE is called dynamically? I couldn't find examples showing how do (I read the entire post, but the subsequent discussion was more about OBJECT oriented programming...)

  2nd question:

  In the second post of nugget of community, there are a few closing notes, one of them: "AEs do not need a while loop." I thought AEs must also use a shift uninitialized register to store information (such as FGVs), and I need a while loop to have the shift register... Isn't it?

  question 3:

  I fall into the usual dangerous trap, jumping through different related posts, and try to understand everything at the same time but I wonder if there is a kind of basic example, which shows the three solutions (ActionEngines, SingleElementQueue, refs value data) for the same task?

  Thanks a lot for the explanation!

  PS: Sorry for using google URL shortened, but the forum of the site gives me error (Please enter a valid url) when I try to paste the normal URL...

  The single line of the element should not be used anymore.  Its purpose has been simplified with the value of data reference.  The concept between the two is exactly the same (reference to a single piece of memory that is locked when read until edited and rewritten in it).  The DVR uses only the Structure of the elements in Place to include the action-Edit-reading where the SEQ relied on the writer is smart enough to actually write data in the queue.

  I like the Action engines.  They are simple and keep everything in one place.  Read you from a register of offset (or feedback node), do whatever it takes with it and rewrite in the shift register (or feedback node).  The fact that it is inside a non-reentrant VI acts as your lock.

  I personally only used once a DVR in a real project and it is only to take care of some composition in my-oriented configuration object (several necessary items to refer to another shared object).  Otherwise, he has been driving Action all the way for me.

• LV 8.2 reentrant vi share data via the global style LV2.

  
  

  If I understand, you want to run multiple copies of the same reentrant VI and the shift of each instance register must be able to have different values. This is exactly what is happening. Create your VI with shift uninitialized register. Do the reentrant VI. Then open in your application main reference the screw using the 8 option which will ensure that the references that you get are really distict. Then, depending on your application either call the screw using the method call by reference node or run a class VI VI using an Invode node.

• RS232 - error handling

  Hello

  I read continuous data from RS232 interface. During communication, there can be that the remote console is turned off due to maintenance work. How can I determine the connection lost? The error on the function 'number of bytes to Port' and "Reading Serial" is empty. Do I have to set a property to enable the processing of the error? What I am doing wrong? I've attached a screenshot of a vi test when it is independent of the connection of the RS232 cable, no error code is displayed.

  Kind regards

  I send an acquisition of start command to the device and I have read the data at all times. Because I'm acquiring the data of both devices simultaneously with different sampling frequencies that I store the last packet of data on a shift

  Register for an acquisition of alternator 'simulation' of the two devices. This means that the property of bytes to the Port must be 15 to read data with VISA Read. Otherwise I use the last packet of 'good' with 15 bytes of

  the shift register. So I can only use the property of number of bytes to determine if I do not get data for a longer period of time using Tick account information for VISA reading compared with the current number of cycles.

• Cannot access windows 8 in safe mode

  running on windows 8.1 I can't access safe mode or safe mode with network.  The steps I used are: shift + reset button, clicked on troubleshoot, click options in advance, clicked on startup parameters, restart clicked, start settings pop up clicked either f4 safe mode or safe mode with network f5. The computer restarts but only in normal mode. Tried to f4 and f5 more than 10 times and it never goes into safe mode when the computer restarts. I tried the command prompts: bcdedit/set {default} bootmenupolicy legacy also {bootmgr} displaybootmenu Yes. These options allow me to choose Safe mode, but once the computer is restarted, it starts in normal mode.

  Hello

  You can try something like this in your skin file:

  AF | question div [id$ = "_search"] {}

  ....

  ....

  }

  If you do not change that a single query panel you need to add the class name to the selector and then in af:query component, you need to add styleClass = "myQueryClass."

  AF | question.myQueryClass div [id$ = "_search"] {}

  ....
