missing data series for port operation in

Hello.

My unit is transfer 51 asynchronous data bytes in frames (each image to 80ms) on six different channels (ch1, ch2, ch3, ch4 rate 19200 baud and other two ch5, ch6 baud rate 115200) and these data series of six diff is received by my system and it should be checked for any error byte... (as I'm new to labview I programmed a long vi) in which use visa read and process the received data. But now, my real problem starts... until some time that my system will be receive data without no loss but aftr some time (say 15 minutes approximately) data loss starts from the track being baud rate of 115 200 and later other channels begin to do the same... But my system is supposed to run for 4hours for a trial of endurance of a plane... If the data loss is very less in number its OK but 3 of 4 frames then starts missing... it's like losing 75% of data... I enclose a wink of my code... It's just for a single port (in a while loop) I took... Imagine I; did the same thing to rest the port in a single while loop... Please guide me where ive that has gone wrong, or is this something to with time delay... pls help me

the thing is always my application system needs will grow more, so I have to rectify this himself in the beginning

  • variable sharing, missing data, the timestamp even for two consecutively given

    Hello

    I have a problem with missing data when I read a published network shared variable.

    Host VI:

    In a host of VI on my laptop (HP with Windows XP Prof.) I write data to the shared Variable 'data '. Between two consecutively write operations is a minimum milliseconds of wait time. I use it because I want to make sure that the time stamp of each new value of data is different then a preview (variables shared the resolution is 1 ms)

    VI target:

    the VI target cRIO-9012 bed only of new data in the way that it compares the timestamp of a new value with the time stamp of the last value on a device in real time.

    Problem:

    rarely, I'm missing a data point (sometimes everything works fine for several hours, transfer thousands of data correctly above all of a sudden failure occurs). With a workaround, I'm able to catch the missing data. I discovered that the missing data have the timestamp exactly the same, then the last point of data read, is so ignored in my data 'legal '.

    To summarize, the missed value is written to the variable shared host, but ignores the target because its timestamp is wrong, respectively the same as the last value, despite the host waits for a minimum of 10 milliseconds each time before writing a new value.

    Note:

    The shared Variable is hosted on the laptop and configured using buffering.

    The example is simple only to display the function of principle, in real time, I also use a handshake and I guarantee that there is no sub - positive and negative.

    Simplified example:

    Question:

    Anyone has an idea why two consecutively data can have the same timestamp?

    Where timestamping (evil) Finally comes (System?)?

    What would be a possible solution (for the moment with shared Variables)?

    -> I tried to work around the problem with the clusters where each data gets a unique ID. It works but it is slower that comparing the timestamps and I could get performance problems.

    It would change anything when I animate the shared on the RT System Variable?

    Whenever data from serial Port, it gets displayed on the indicator chain but clears quickly, but I want some data comes it does not erase the old data and new data to add with the old data.

  • Point cloud with missing data and 3 sets of data

    Hello

    I'm doing a scatter diagram that has 3 sets of data in it (i.e. 3 plots on the same graph), except that 2 of my sets of data have a missing value while my third set has all the values. I end up getting 2 lines that are disconnected. I can't just remove the line containing the missing data for the 2 sets of data because since my category axis is time, my data points get shifted and no longer appear at the right time. This is the chart that I have.

    Thank you.

    Hi Gabrielle,.

    If there is a diagram of dispersion, the x axis is a value axis. If you have auto selected for the min and max values on this axis, the scale may change when you remove the data point, 15, 85, but the rest remains in the same position relative to the values on each axis of ordinates. What change will be , however, is the curve on which 15 85 approached a local y maximum.

    Scatterplots will always leave a gap in the line/curve of connection where there are a pair of missing data. There are two ways to close the gap.

    If the chart is an essentially linear relationship, you can use a calculated value is pair up with the lack of value x. The downside of this is that the representation of this point will be indistinguishable on the map of the other data points, measured.

    A better way would be to make two tables, one with the full data set, the other with the partial sets, but with the pair missing completely removed.

    Adjust the cards the same size and have the same scales on each axis, then just remove one of the cards except the data points, the curves connecting the data points, the x axis of ordinates and the legend showing the color and the forms used to plot each series.

    Give a graphic a transparent filling and place it in front of the other.

    Kind regards

  • HOW TO READ DATA SERIES WITH SYNCHRONIZATION

    I have a question about my application for the acquisition of data in series. In my application, I use visa read to acquire data series sent by an inertial measurement unit. When I first put the sensor, it sends data in the following one time format:

    1:0 x 8011 header followed 1 data word for Adler, 1 data word (each 16-bit word data).

    and the sensor then starts sending the data in the following format:

    2:0x7FFF header followed 1 data word for checksum, 9 data word (each 16-bit word data).

    (Note: checksum is defined as a 2s - complement of the sum of 16 bits of the rest of the entire message)

    In my application, to simplify the problem, I use a wait function to ensure that the initial data header 1 tag is sent. Then I start reading using VISA Read 20 bytes (header 2 more words of associated data are 20 bytes), as I'm mainly interested in the data header 2 tag words.

    However, when I do this, the data that I get do not begin by 7FFF character and, accordingly, my 20-byte data cannot be parsed correctly. My question is how can I do the "VISA read" block read the serial port when data are preceded by '7FFF '.  Once I have solve this part, my strategy will be assembled data read 20 bytes (including the header of 4 bytes) and analyzed accordingly.

    Another question, I wonder if you can tell me how to use the given checksum it is defined as "a s 2 - complement of the sum of 16 bits of the rest of the entire message". Note the data that contains the header 1 tag is 1 post.

    I would appreciate if you have responded to my request.

    Thank you!

  • Why the NDP module says "you are not allowed for this operation?"

    Hello world

    I hope you can help me with this problem!

    I'm playing with the NDP module has a message saying 'you are not allowed for this operation.

    This happens when I try to create a new project and try to open the window to select a project type. It also happens when I go to the ADMIN and add new types of projects?

    Is there a role limiting me or does some other underlying problem?

    Thank you in advance.

    Hello

    I think that you might miss an active project type category.

    Go to Admin-> NDP-> categories of project types.

    You must have at least one category that is active (which is indicated by a green check mark).

    Once at least one is activated, you will need to go to the Cache and rinse the taxonomy of cache (just to be sure, I would empty Admin Data Cache Group as well).

    Then you can go to the Admin and configure your project types.

    Let me know if you have any questions,

  • Unable to recover the old data synchronization after reinstalling operating system

    Hello

    I was using Firefox 26. Recently, I've upgraded to the latest version. A few reasons, I had to reinstall my windows 7 OS.

    After I installed Windows 7, I installed the latest Firefox and tried to synchronize data. I was unable to connect because I forgot the password. I tried using the link "password forgotten", but he said there is no such thing as e-mail id. It was surprising to me. I'm still all emails, including the secret key, I used to add new devices earlier, since Firefox in my mail box.

    Since I left without another option, if I'm creating a new represent now on Firefox with old email ID. The account is created successfully. Again, it is strange to me. However, my old data are not synchronized.

    I need the old data. Help, please.

    Thank you
    Ravi

    Sorry, Sync was not intended to be used to backup Firefox data before reinstalling the operating system. Its purpose is to synchronize several separate installations of Firefox, usually on the various devices.

    The old version of Firefox 26 uses another version of Sync, the latest version of synchronization happen in Firefox 29. The largest variation in sync had to do with the recovery key ('secret key') - is no longer something to see the user or has to deal.

    You should have installed Firefox 28 or earlier and then connected to your account synchronization to recover your data and then put updated for Firefox 32. By creating a new account with the same email address, your data has been wiped out by synchronization servers to allow you to start a new.
