Tunnel of automatic indexing problem

I have a data acquisition program that uses an Auto-Indexed Tunnel in a loop to process and display data in a table 1 d.  The program behaves strangely with the first value in the array (the point where the program worked, in a few seconds).  13 other values in the table all correct update, but the value of time always shows approximately the same number.  The loop is scheduled to update the front values once per second.  If I use a table outside of the loop Index block For to get the value of time out of the matrix, I get the correct value for time increments upward by about a second each time that the loop runs.

So basically, when the value of time is passed through the auto-index Tunnel, its output fluctuates up and down a few tenths of seconds each time the loop is executed (remaining to a single value... usually about 90, even if it changes each time I run), instead of starting with 0 and increases with time as the summer running program.

I'm under LabVIEW 8.5.1

Thank you

Sam

Because I have no data acquisition installed, I can not tell what is the size of the array is, but if it is greater than 14, the later elements overwrite time because 0 is also the default value. For safety, I add another case (empty) (e.g. - 1) and make it the default.

A lot of things very unwise, for example in the dataHCC.vi 'calculate', you add an empty array in the table. This really does not something useful, right?

  • Through tunnels of automatic indexation to write data files?

    Hello

    I use neither-controller to control a servo and position and torque data collection. I want to write data to the TDMS files.

    Recently, I learned about the design of producer/consumer model and I thought it would be a good approach to ensure that writing the files didn't slow down my timed loop of data collection.

    However, I also realized that my program seems to work well if I wire the data that I collect the tunnels of automatic indexation. Can I use a structure that executes only after the entire collection of data is made to write the charts that I built to TDMS files.

    Is there a reason that would make the last method against? Can the tunnels of idexing auto slow my loop enough to concern him? I collect only about 5,000 points of data for each channel.

    See you soon,.

    Kenny

    In my opinion, the main consideration is timing.  If you use consumers/producers, you essentially make writing while the data collection process is "pending" the next item to collect.  It should be the case that the consumption will be faster than production, so at any time, 99% of the data are already written, Yes (perhish forbid!) if the program crashes, you already have most of the data on the disk. fo

    Alternatively, you can use the tunnels and send an array of 5000 points (from the tunnel exit) for the writing process.  This requires it to be rather than parallel series - no writing occurs until all the 5000 points are generated, and the writing process, instead of is almost as soon as it starts, takes 5000 times longer (more or less).

    The series is 'simpler', especially for a beginner.  The producer/consumer, if you understand the design model, would be my preference.

  • Automatic indexing does not as soon as the first element of the array.

    Hello

    I have a state machine that uses automatic indexing in most of his State to write the registry to set the part for some test.  When the state machine reaches the section 'Now playing' (the fourth State, second battery sequence) I have a picture of two equal elements related to looping for to write the required registers for this specific test.  When I enter the current state read the the first address is the second element of the array which is '1' location and not the first address that must be '0 '.  I closed the program and restarted LabVIEW but I always get the second element in this loop that maintain the form part works correctly and I get an error because the first element turns on the chip.  Is there something I'm not see when it comes to self that he would keep from starting at the first element of indexing?  Please take a look and let me know what I can do wrong.  I have attached the main program and the print loop results screens and test probe.  Any help will be great.  It worked last week.

    I don't see no problem at all when I copy the loop in an another VI in order to run it. Your jpg shows nothing on the values of the probe.

  • Spotlight indexing problems

    I cleaned files on my hard drive - re-filing of certain documents (pdf files) rename photos - adding text says pictures of things like that.

    Have had occasional problems with gel - startup etc - that only seem to happen after a cleaning.

    By checking newspapers led to a finder error - saying his flight, or a job did not finish before the closure.

    Never really used it yesterday and it deleted all the files the search-, but if it ends up falling on indexing - or anyway to clear it.

    I was wondering if the problem is that indexing never delete old stuff - maybe the problem after snow leopard from is that the re-indexing after each update is in fact eventually causing an overflow (leak) because the size of some user data was not provided (or someone to pull).

    I'm on snow leopard on a Mac Pro 2008.

    Update on this problem...

    If you are looking for articles on how Spotlight indexing problems - other sites of mac users - OSXdaily, for example - to have discussions on this topic, including advice on how to use a statement in a terminal to turn it off completely - the problems are similar to those that I have - then it's perhaps a question that has not been reported to Apple.

    My problem seems to be a combination of chaining a large number of files and moving them - combined with Time Machine.   I have restore a plu Time Machine folder which contained 1200 small pdf files - which lost some how because of permission issues when I moved them.    As well as readonly files I could not restore them unless I put them in the box and then changed all the permissions read and write.   The older folder was actually the first time machine upward when the main folder in question had been copied from the CD for the office (he gave no permission to write to the subfolders in the main but to load data)

    My time machine is now stopped and I ejected the drive until I decide how to restart backup.

  • Automatic indexation 2D array in the loop For - what is happening?

    I found many sources dealing 1 d tables in a loop For or a While loop, using automatic indexing, but nothing on the tables of higher order.

    I work with a program that feeds a 2D array in a loop (see table).  From what I see, it looks like this the results of automatic indexing in a 1 d, the first column of table 2-D table.

    This is the expected behavior, and it would hold true for arrays of higher order, table 3D for example?

    Is it possible to refer to the second column rather than the first?

    N ° it auto-index through a line at a time table.  You will get a 1 d table which consists of all of the columns that make up each row in each iteration.

    This is the expected behavior, and it would hold true for arrays of higher order, table 3D for example?

    Yes.  Automatic indexing on a 3D Board will give you a table on each iteration of each page 2D.

    Is it possible to refer to the second column rather than the first?  This question applies once you understand the first response.

  • What is the physical meaning of automatic indexing of table entry...

    What is the physical interpretation of the automatic indexing. ?

    You wire up a table on the edge of a loop, it sequentially will index the table for you as he travels the loops. A While loop will also do this, but it is much more common on loops For, therefore, loops For making automatically while the While loops must be 'right click' and said to the index in the array.

  • automatic redirection problem 9.3 IOS

    I'm almost in tears at the moment that my Apple products are practically unusable - I even had to resurrect my faithful laptop windows in order to access the Apple support. We have pro iPad and iPhone 6 s, 6th Gen iPod, iPad Air II and since upgrading to ios 9.3 navigation or by clicking on the links on any device with java script enabled because of the problems. With all the loading links active js, but at the last second auto redirects through a series of ad sites onclick (up to 12 redirects in some cases, sometimes only half that much). Each series of redirects is found in an amazing where I won a new product from apple or £ 1000 to spend in Ladbrooks or trying to take me to the App store. Some end on a popup where the only option is to click to access a site that cannot be left or to force close the application/browser and try again.

    After reading the forums, I tried the following (several times and their many variants):

    Updated to ios 9.3.1 (thought what made the case but 5 minutes in and everything happened in shape yet pear).

    Reset the browser history

    Reset the network settings (wish I had not done this - network customer support left 6 settings)

    Forced shutdown of all applications

    Forced shutdown of devices

    NOTHING (except the js that is not really a solution to this problem by disabling) stopped the automatic redirects - they happen links in emails, messages, applications, Web pages, directly from search results, Safari app, Google app, and all the other applications that load external Web pages.

    I now have a house full of devices that are almost unusable - js is used in almost all websites. Cannot even log on this forum of support without him, so back to the computer windows laptop.

    Eager and willing to try almost anything to solve this - my frustration level is ridiculously high - for someone who works in THIS medium that is a pretty damning level!

    Hope someone can help me here. Thank you.

  • Indexing problem

    I'm running a state machine in a loop and wish to record the errors that occur and diplay on the fron Panel. Because there are many caases and many mistakes possible I want to make sure that all is displayed something like the following.

    Error of gain coefficient

    Setpoint error

    Response error

    etc, but my problem is that the table of errors only displays an error message and replaces it if another error occurs. I thought that indexing would allow me to 'stack' errors so I see all erros that occurred during my test. The "case"TRUE"in the right lower structure case does nothing with the CR. Any suggestions?... Error writing to a file would be easier?

    No, no, no. You must pass in the table since the shift register. An entry in the table build is connected to one and the other input is connected to the error.

    Have you taken the LabVIEW tutorial or resembled any of the examples? An example that illustrates an instruction box with a shift register and table construction is called "separate table values. It is listed under Fundamentals > tables and classes.

  • For automatic indexing loop should not index empty array

    Hi guys,.

    sdfsdfsdfadgadf wrote:

    So when I was debugging, I saw at the 3rd row and 4th iteration of line, out of the inside OF the terminal loop index outter loop is [].

    Should not the terminal of the index of the outer loop treat [] as 'skip it '?

    In this case, the tunnel of indexation in the outer loop takes an empty 1-d array and adds it as a line to the 2D table. Because the 2D tables can not be serrated, it fills the remaining elements of the line (all) with the default value. Maybe we could say that an empty array should mean 'add all', but this behavior goes back very far and I don't know what effect this would have. As mentioned, it is easy enough to do what you want with a conditional append in the outer loop.

    sdfsdfsdfadgadf wrote:

    I mean what you described certainly applies if [] a something, but in this case it didn't. To prove the point, try something like this:

    Check the size of the table. You will find that it is 3,0,0. In other words, you have 3 pages, each with an empty 2D array, which is exactly what builds your code.

    I try to avoid dealing with > 2D paintings and which deals with the cases where they can be empty, so I don't remember the details of why this happens, but IIRC, it follows the rules of the system.
