Streaming data from CSV

I'm new to labview and am unable to determine the correct way to perform the following function
I have a CSV file that has about 8000 data points (1D), that were captured as a Voltage every 25ms.
I want to turn around and simulate the device I captured the data from.
I am able to import the CSV using the "read from spreadsheet"
I have set up a LOOP that repeats every 25ms (the same as capture rate), and I have the code to feed to the output device.
I'm missing the code that extracts one cell (element) from the array I imported so it can be feed it to the output and then increment to the next cell (element) on the next loop.
I've tried the index array but it does not seem to work 
Thanks for the assistance.

 have attached the csv file and my crude beginning of the .vi file.  I currently have a sine wave feeding the analog output device which works.  I wish to replace the sinewave function with the data in the CSV.  Every 25 ms the output should be updated with the data in the next cell. I'm bacically simulating a waveform that was captured from a device in the field, I wish to simulate it in the office for testing some PLC code
I am using a LabJack U3 for the I/O.
Thanks,
dpjkw

  • Loading data from .csv file into existing table

    Hi,
    I have taken a look at several threads which talk about loading data from .csv file into existing /new table. Also checked out Vikas's application regarding the same. I am trying to explain my requirement with an example.
    I have a .csv file and I want the data to be loaded into an existing table. The timesheet table columns are -
    timesheet_entry_id,time_worked,timesheet_date,project_key .
    The csv columns are :
    project,utilization,project_key,timesheet_category,employee,timesheet_date , hours_worked etc.
    What I needed to know is that before the csv data is loaded into the timesheet table is there any way of validating the project key ( which is the primary key of the projects table) with the projects table . I need to perform similar validations with other columns like customer_id from customers table. Basically the loading should be done after validating if the data exists in the parent table. Has anyone done this kind of loading through the APEX utility-data load.Or is there another method of accomplishing the same.
    Does Vikas's application do what the utility does ( i am assuming that the code being from 2005 the utility was not incorporated in APEX at that time). Any helpful advise is greatly appreciated.
    Thanks,
    Anjali

    Hi Anjali,
    Take a look at these threads which might outline different ways to do it -
    File Browse, File Upload
    Loading CSV file using external table
    Loading a CSV file into a table
    you can create hidden items in the page to validate previous records before insert data.
    Hope this helps,

  • Error while load the data from CSV with CTL file..?

    ORA-00917: missing comma

    Possible Solutions
    Make sure that the data source is valid.
    Is a member from each dimension specified correctly in the data source or rules file?
    Is the numeric data field at the end of the record? If not, move the numeric data field in the data source or move the numeric data field in the rules file.
    Are all members that might contain numbers (such as "100") enclosed in quotation marks in the data source?
    If you are using a header, is the header set up correctly? Remember that you can add missing dimension names to the header.
    Does the data source contain extra spaces or tabs?
    Has the updated outline been saved?

  • Stream data from a subvi to the main vi

    Hi
    I’m wondering if someone can help me. I’m trying to stream data from a sub vi to the main vi without opening and closing the sub vi continuously. The data also needs to be extracted from a while loop within the sub vi.  background info: The sub vi controls a photomultipler tube, which once it is on it is best kept on. The PMT signal is generated in while loop of the sub vi. Attached are some basic vis showing what I’m trying to do.

    If you are streaming measurements continously I would consider using a circular buffer instead of the queued producer/consumer approach.
    Check out this implementataion of such a buffer, use only this if your DAQ device does not have an internal circular buffer.
    https://decibel.ni.com/content/docs/DOC-20403
    Alternatively if you are using a DAQmx device, consider using the device buffer for sharing DAQ data between loops.

    Bom Dia Saille,
    Eu acredito que o que você tenha hoje seja isso aqui (Desenho bem simplificado):
    Hoje o que você tem é o Aplicativo do Medidor + USB Driver controlando o seu medidor. Basicamente, sua aplciação está dividida em três camadas:
    Aplicação - Onde estão as funcionalidades principais do programa (interface com o usuário, apresentação de dados, geração de arquivos, etc.)
    VISA - Uma arquitetura de Software para controle de instrumentos. Basicamente, ele se comunica com o Driver USB para poder enviar e receber pacotes de dados através do barramento USB.
    Device Driver - Intruções de SW de baixo nível para controlar um periférico através de um barramento.
    No desenho, eu aponto duas camadas onde você pode tentar atuar para automatizar suas medições:
    Aplicação - Você pode usar o VI Server para controlar o Aplicativo do Medidor (Se este aplicativo tiver sido desenvolvido em LabVIEW, o que eu suponho ser verdade). No entanto é necessário saber se o desenvolvedor do produto permitiu isso (Veja Using VI Server to Pass Data Between a VI and a LabVIEW Executable). Outra alternativa é conversar com o fabricante para ver se ele desenvolveu alguma API (Application Programming Interface) para que você consiga controlar o instrumento diretamente.
    VISA - O LabVIEW Fornece uma API chamada NI-VISA para poder enviar e receber informações através de diversos barramentos (Veja Serial Instrument Control Tutorial)
    É possível acessar o Driver diretamente também, mas eu não recomendo. O resultado não compensa o esfroço!
    Espero ter esclarecido suas dúvidas e espero que você tenha sucesso na sua aplicação!!
    Atenciosamente.

  • How to stream data from TDS3000?

    Hi there,
    I would like to stream data from my scope into Labview for further analysis.
    Hardware: Tektronix TDS3014C
    Software: Labview SignalExpress 2.5.1 + Tektronix Extensions
    I don't exactly know when the interesting transient signal appears, therefore I would like to save ~5-10 s of streamed data.
    Right now I'm getting just fractions of 2 us and the scope switches into waiting for trigger.
    Is there a way to deactivate trigger, or a keyword I could search for?
    Thanks for your help,
    nook
    Solved!
    Go to Solution.

    muks,
    I think you got this post confused with another.
    nook,
    You can rarely continuously stream data from a GPIB scope. You can check the manual but often the scope cannot transmit at the same time it is acquiring so you have a sequential operation of wait, trigger, acquire, transfer, repeat.
    Can't you set the trigger for the transient?

  • Import data from csv to SQL database

    How to  Import data from csv to SQL database through BLS-xMII?

    Hi,
    if you using Oracle, you may also use the bulk insert with MII. You can use the String List to XML parser to convert your CSV to XML, and then use a query that calls a stored procedure which does the bulk insert.
    Also have a look at thread [read XML file into stored procedure|http://forums.sdn.sap.com/click.jspa?searchID=63850236&messageID=7455643].

  • Loading data from CSV to Unix database

    Hi All
    We had copied CSV into UNIX box and tried to upload data from CSV to oracle. We are able to load data from CSV's but some CSV are loading perfectly, but are loading extra character into the column.
    Even I tried by putting the CSV files in windows and load the data into UNIX database, I am facing the same problem.
    But if I use the same CSV's and load data in Windows database, It is working fine.
    Can anybody suggest me the solution.
    Regards,
    Kumar.

    ... oh, what a confusion. I still answerded in the ittoolbox group:
    "Hi,
    the problem are the different character sets in the windows and in the unix environment. So some of the characters are missinterpreted.
    Is the database where you first loaded the csv's from a unix box also on unix? How did you copied the files? Via ftp? I hope in ascii mode? "

    These quotes are part of your data file. Most CSV-parsers remove those quotes.
    If you are using an external table you can remove them by something like this for your access parameters
    ORGANIZATION EXTERNAL
      TYPE ORACLE_LOADER
      ACCESS PARAMETERS
        RECORDS DELIMITED BY NEWLINE
        FIELDS TERMINATED BY ','
        OPTIONALLY ENCLOSED BY '"'
    But if you want to remove them from your existing data use this
    update your_table
      set col1 = trim( '"' from col1 )
    Note that in some CSV-files wich use an enclosing character the enclosing character is itself is used as an escape character to use the enclosing character inside a field.
    For example a field might be "Some text with ""this"" enclosed"
    To correct these fields you might use another update
    update your_table
      set col1 = replace( col1, '""', '"' )

  • Help Me... How to get Data from CSV File...?

    Hi Everyone..!
    This is yajiv and am working in CS3 Photoshop platform. I know about Java Script. Is it possible to get the data from CSV files. Actually our client use to send us the CSV files which contains a lot of swatch name and reference files in one particular image name.
    Actually how we work on that CSV file is, first we copy file name to search that CSV file. then get the result to paste into layer name. This process continue till the end of swatch.
    Thank in Advance

  • Streaming data from cRIO

    Hi everybody,
    This is quite a general question and I am looking for some pointers\opinions\suggestions.
    I want to stream data from several channels at diffferent rates from my cRIO to the host PC. As far as I can see there are three options:
    1)  Use a network shared variable (NSV) for each channel and read them in a loop on the host PC.
    2)  Use one NSV which uses a cluster of an enum and variant. In this case the enum specifies which channel (and therefore data type) the packet contains and the variant contains the data.
    3)  Use STM to stream the data over the network using TCP/IP
    These are my questions/thoughts:
    1)  not very scaleable as each NSV has to be read individually also just seems messy!
    2)  Seems nice and clean and scaleable, multiplexes the data into one channel. I am aware NSVs are not quite as efficient as directly using STM TCP/IP  BUT... is there an additional (significant) overhead converting all the data to variant?
    3) According to the documentation on NSVs using TCP/IP is the fastest way to stream the data. This method seems to offer the same avantages as (2) - clean, multiplexes the data. BUT it does add complexity in developing the cod. Also the data is still flattened to string, is this much different than converting to a variant?
    THE QUESTION: is method (2) a reasonable compromise if the absolute highest data rates are not required?
    Many thanks,
    Steve.

    Hi Steve,
    I have been looking into this problem for you. It seems that each of the three options you highlighted could be used to achieve your goal though since you want to stream multiple channels method 1 would be highly inefficient and therefore should not be considered for this application. I would suggest that method 3 which uses TCP/IP to stream the data over the network is the optimal solution in this case though as you have alluded to, this does add a level of complexity. If you decide to pursue this option I have found a really useful link provides more details about this methodology and a LabVIEW example which should help you get started with the coding. I have also found this link to a forum which may be of interest to you (especially the final post by Kurt).
    I would also like to add that I completely agree with Brian K, in that I believe method 2 is a very acceptable compromise, especially if high data rates are not necessary. 
    I hope this helps.
