Data loss when writing to the worksheet

I worked on a VI to acquire data from two instruments and save them in a spreadsheet. To do this, I wrote two screws slot for data - one for a scale and the other for a conductivity meter and temperature. Regardless, each sub - VI works well; However, the conductivity meter sometimes writes a 0 value in the worksheet in the main VI. I thought it could have been a problem with the sub - VI, so I wrote a small article to catch and eliminate any 0 result product (I've put in place to collect an array of results and get the average to reduce noise). It did not work and every 5 or more data points, he writes a strange value or NaN. I think there is a loss of data in main VI caused by one of a few things:

-The response time of the scale is the order of milliseconds, but the response time of the conductivity meter sends a signal every 5 seconds. This difference would cause a loss of data?

-In the main VI, the scale readable Subvi is configured to perform a loop for to generate the table in the main VI. On the sub - VI conductivity, I configured it to run the loop in the Subvi. This difference would result in a loss?

I have attached a few pictures of the block diagram to help.

Thanks for the help, guys!

I thought about it. By running the loop inside the Subvi, rather than in the main VI, he was losing some data as it came out (?). In any case, once I put in place similar to the VI scale reading, everything worked fine. I think that, anyway. It will not look like you guys don't have nothing, but forcing me to put the problems on paper has helped tremendously. Thank you!

    Original title: AOM moved only to 94%

    When I install Age of mythology, I have put on disc 1, do all the stuff, he moved to 45%, and then it asks me to put in disc 2. I do, and he moved to 94%, which is the stage that she calls 'Copy texture.bar' then it stops and I can hear the disc turn and stop repeatedly. After about 10-15 minutes, I get an error message and it said:

    Thank you

    You need to do a little basic troubleshooting. Make a right-click on the son goes into the loop, and selection "probe". After you run the VI, the content of the probe and see if there is no data there. I had to put a delay in the loop of the acquisition or specify a number of samples to get the data in a consistent manner.

  • delays when writing with the pec in Portege M200

    I face a very obvious slow in exercising the hand writing in tablet mode.
    usually, I write "with a single note" and writing is instantly displayed in normal writing on paper.
    but when I tilt the screen to be in tablet mode, what I write is not displayed unless I finished the whole word, and display is normally extremely slow.
    Although if I tilt the screen to normal laptop mode "with the same session a note" the speed is back to normal.
    Please notify.

    Hello
    I ve tried to simulate your problem with my M200

    I couldn't see a Performance distinction between modes of Tablet PC and the PC Normal.

    Could it be that you´re by using the Tablet PC Modus in battery operation?
    Then of course as a result of the power management the M200 runs slower.

  • Problem of width of column writing to the worksheet

    Hello world

    Does anyone know how to adjust the column width when you use the "write to the spreadsheet" vi in Labview?

    I always have a long string as the title and the excel file would show only part of it after that I dump them to it.

    I'm not sure that the width setting is Microsoft Excel or Labview himself.

    Any help is appreciated,

    Thank you very much

    + Kunsheng

    Hi Kunsheng,

    If you use the function 'Write to a spreadsheet file', then you can not set the width. You create a txt file with this function, not real excel file. For a true Excel file, you can use ActiveX.

  • Writing in the worksheet

    Hi all. I have my attached Vi, which does nothing more than feeding an output voltage of 1 to 5, each 3-seconds, unless you press the stop button. I don't like the stop button, I chose because, if accidentally put in true state before you run Vi, it throws an error I do not know how to recover from. However, this isn't what concerns me is, for the moment. I'll try to fix it on my own first. What I am not sure do now is to know how to write a value in each case on a spreadsheet structure. I tried to use arrays and store the data of each case of effluent to a location on the table, without a bit of luck. I went through section 1 basic tables to see what I'm doing wrong, did not help me. It must be much easier I have do it. First of all, am I right to assume that I must first write this in a table, and then transfer the data at the end of the cycle Vi, or should I write directly to a worksheet after the close of each business structure? I thank very you much.


  • RT-target short-term memory when writing to the network stream

    Hey there,

    I have a program that transfers data acquired from the FPGA to the host PC. RT - VI reads data from the FIFO DMA and writes it to a network stream (BlockDiagram.png).

    Now, I am a phenomenon, that the RT-target load his RAM until it is full and accidents.

    I have no idea why this happens, network flow buffer is empty, all the items are read by the host, and there is no table built by indexing or so.

    Someone has an idea, how I can handle this?

    Best regards

    Hey there,

    I had the problem solved,

    the problem was the buffer of the sender endpoint was too big. Unlike this problem: http://digital.ni.com/public.nsf/allkb/784CB8093AE30551862579AB0050C429, wasn't the growth of memory because dynamic memory allocation.

    It is just the normal speed of the cRIO while allocating buffer. The sender buffer affecting many smaller, memory growth stops at a specific level (DSM2.png).

    It is strange, this use of memory that grows slowly, despite the creation of the endpoint with preallouee buffer, so that its use dark quickly when the VI - enforcement stops...
