String to number conversion problem

I have a VI that pulls in data from a device using VISA, and I got it on another computer to work a few weeks back. I had to transfer the VI to a laptop computer to run a few tests, and now I can't make it work. I am unable to put my VI because the laptop on it's is unable to access the network companies, I will do my best to explain it all, I apologize for the inconvenience! My problem is not however with VISA, it's with an exit VISA number conversion chain.

I have attached a painting drawing of VI to better explain it.

I use the block series Visa football match in baud rate and all that many good things to the unit and port settings set of device management. Then, a while loop is entered. The loop will run until you press the stop"" button. The next block of visa is the writing block, he asks for a reading of the device. The next block of visa is the first block of reading, he returns playback in the form of "NA-XXX. X' where x are numbers. The next block of visa is the second reading block, this block just echoes back the command sent to the device. Playback of the first visa read block, "NA-XXX. X' is going exponential/fractional chain to digital converter.

When you perform a run/debug to highlight run, the release of visa reports the correct value, is the value of the device reading - however the string to number converter generates a 0,000, no matter what channel number is. I am at a loss as to what may be wrong because it's the EXACT set up I had to work very well a few weeks ago!

I'm using Labview 10 on the laptop, the old computer was labview 7. I'm guessing that this is perhaps the rub... I Redid the VI from scratch, although I have not opened the old VI in labview 10.

Any help would be appreciated. Again, sorry I am unable to attach the VI.

Would it not have been easier to just post a screenshot? You might also have used the Tool of Capture of Code. (Which reminds me that I need to install it to my previous versions of LabVIEW, as evidenced by the screenshot I took. )

As to the question: you probably either:

  • employee analysis of chain initially and when you rewrote the VI you used the regular string conversion functions.
  • Wired an offset value in the string to the number function.

  • The decimal string to number Conversion, cutting necessary zeros

    I'm new to the forum, but have been using labview for awhile. Finally found something that really puzzled me, hope I can find someone who is smarter than me! It may be something obvious too, but here goes. The attached vi is the cause of the error. I have a serial number I need to convert a decimal string into a number, I use later the number of "math" so he need as a number. The system always receives a serial number of 6 characters (ie. 123456), but today the system has received a serial number with two leading figures of the scale (ie. 003456) zeros. This compensation of all the bells of alarm stream (sent 4 digits), but the error found that started the 'intelligence' at the beginning of the monitoring program. I would like to know if there is a way to force the zeros in the decimal number in string to not shave off the coast of the 6-digit value above.

    File is located in LabVIEW 2014

    Ideas or comments, thank you!

    The problem is not the string functions.  This is the display format for your digital indicator.  Change the properties on that.

  • Varchar2 to the number conversion problem

    I have some difficulty conversion strings to numbers. On my Oracle 9.2 server, it gives me an error ORA-1722:
    SELECT TO_NUMBER ('1.2') OF DOUBLE
    Apparently, this is because my server is configured to use the Greek number format (comma instead of decimal point) and substitute "1.2' above with '1.2' will work correctly."
    Is it possible for me to convert strings with decimal number type, independent of the culture so that my application will not have to depends on the locale setting of the server?

    Thank you.

    Hello

    Welcome to the forum!

    If you don't want to change the NLS settings for your session, you can specify what settings to use for a particular call to TO_NUMBER (and other features), like this:

    ALTER SESSION     SET NLS_TERRITORY = GREECE;
    
    SELECT     TO_NUMBER ('1.2')     AS wont_work
    FROM     dual;
    
    SELECT     TO_NUMBER ( '1.2'
                , '999999999.999999'
                , 'NLS_NUMERIC_CHARACTERS = '',.'''
                )          AS n
    FROM     dual;
    

    The output below shows the TO_NUMBER 1-argument fails, but the 3-argument TO_NUMBER works:

    Session altered.
    
    SELECT  TO_NUMBER ('1.2')       AS wont_work
                       *
    ERROR at line 1:
    ORA-01722: invalid number
    
             N
    ----------
           1,2
    

    The actual format of the string (the first argument) should not match precisely the format mask (the second argument). You can include signs, or omit the decimal points, so '3', ' '-1,2. '-3', ' + 1.2 ' and ' + 3' will be all converted correctly.»»» "

  • Sub - VI with the entry as a string og number

    At this small Subvi. I wonder if I could make it more flexible and be able to take the string and number as a value ('value dbl' market) entry.  Is there some sort of variable of variant type that could be used?

    It is possible with the key to write OpenG (varying) _ogtk.vi. But the problem is that when you want to read this back, you need to know what type it is. If you write to a different section of the config file each with a specific type, the TI will work. With this solution, you must use the key to reading OpenG (varying) _ogtk.vi to read and convert the value to LV

    Another way is to use Get Type Information.vi of the Variant Data Type palette. The trick here is to convert double or string before saving it in the config file (wire structure dealing with the output type of the vi and do conversions in the case of type dbl and string). Here, too, you must use a different section, one for dbl for string. Here, you use the standard Read button live file configutaion palette.

  • Is the locale-specific number conversion chain?

    I would like to know what effect the computer's regional settings may have on the string number conversion in AS3. Specifically, in locales that use a comma as the decimal separator instead of a period, different conversion methods (Number() function, parseNumber(), Builder of the Number() class) they treat the comma as decimal separator? None of the documents I've read resolves this problem and all the examples use periods as a decimal separator. I suspect periods in strings will always be handled as decimal separators (and this is the behavior I want), but I would like to know for sure.

    FTR, an Adobe employee comes to informs me on programmers list that the answer to this question is no. period is always interpreted as a decimal separator, regardless of the location of the BONE.

  • "Decimal string to Number.vi" bug in LabVIEW 2009 SP1

    The "decimal string to Number.vi' seems to be the conversion of the input data in the type int32 internally even when the input tape in vi data is expanded floating point (no points of constraint).  This is causing me grief.  See attached vi

    Hi, Greg.

    When there is an error in a trigger, the line numbers in error messages are compared to the first statement DECLARE or BEGIN; often, it is a few lines after CREATE OR REPLACE TRIGGER. Post a few lines after what you have already posted.

    If you do not find the error, then create another table to test this and create a small trigger on that table, who did just enough to cause the error. Then, you will be able to post the complete relaxation, and the code needed to recreate the problem.
