• little binary string in array (of TCP read) to the table of Boolean LV (and back)

  I would like to ask what is the easiest way for the next conversion? We use aTCP Read function to read an incoming binary string to a S7 API using LabVIEW. We know that LabVIEW stores a Boolean value to 8 bits. The incoming binary string contains 14 bits (representing 14 indicators of status). What is the best way to convert these values of 14-bit LabVIEW Boolean table?

  In addition, we send a LAbVIEW Boolean table in the PLC data (to write a TCP) string containing status bits.

  Thank you very much!

  Martins wrote:

  This 30 bytes contains some data more, including 14 bit flags (size is 14 bits). Since the PLC cannot put 'together' (16-bit) words at his side before sending data TCP, 14 bits is padded with 2 bits holding no valueable info.

  Then the solution is simple.  Take your 2 bytes and unflatten in a U16.  Then use Boolean table number.

• By the way the table of Clusters with binary strings via adapter LabVIEW

  I need to go through LabVIEW adapter table clusters containing binary strings.
  These data will be subsequently stored in the MySQL database.

  I need to force the option "Binary string" for the ValBinary element, even if my output array is empty.

  Is this possible?

  Used versions: TestStand 4.2.1 + LabVIEW 8.6.1

  Attached file: valbinary2.vi containing the clusters of test output array.

  Howdy Jean-Louis,

  My apologies, I'm not quite your question. You're right that LabVIEW does not know that a string is a binary star strong; LabVIEW, chain stores in a format of Pascal, looks like all the strands in the same way. Because TestStand stores strings in the C type format, on the other hand, the null (0x00) characters can be confusing when interpreting strings in TestStand as you learned to understand. That is of course why TestStand offers the feature to interpret strings as binary strings.

  As Sylvie refers to his post, to illustrate his point I created within TestSTand an array of the same type of data customized to store past out of your valbinary.vi of test data. Test patterns, I also edited the outputsome constant values to the cluster VI. (See the following screenshot). Note that the last string (named ValBinary) in the cluster contains a hexadecimal string with a null character that is inserted as the 3rd on-screen character (before the actual end of the string).

  

  Here is a screenshot of the created sequence file that calls the VI and then displays the number of items in the table from the VI to the user.  Note that the Locals.MyTestData table is empty before the execution of the sequence.

  

  Finally, as the execution of the sequence, I opened the Variables pane to view the contents of the Locals.MyTestData table. Here, I have confirmed that the "binary" string of LV was successfully passed in and stored by TestStand.

  

  Finally, the popup message in the second step of the sequence shows indeed a message indicating there were two elements in Locals.MyTestData.

  This sequence has been able to run successfully even without manually specifying a size of Locals.MyTestData beforehand. TestStand dynamically allocated the necessary elements to store the results of test valbinary.vi.

• How to convert the binary value to a binary string in labview?

  Hi all

  I need to convert the binary value to a binary string. We have decimal or hexadecimal or octal number to decimal string, hexadecimal and octal string

  Hi pgm, use the function 'Format to a string. See the attached example. "%b" is the binary number in number in string format specifier.

• "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

  This bug is still present in LabVIEW 2010?

  Thank you

  Richard Ballantyne

  There is no bug. You use the wrong function (see Help) If you want a floating point output. Use Fract/Exp string to a number.

• String conversion number

  Hi all

  I need to convert the string like "-73.28" to the number - 73.28. With decimal string to number Vi I get only - 73,00 output with "-73.28" Dim input As string. What I've done wrong? How to get the required results? Also, note that it must be. the number of output!

  Thank you!

  Hi Nina,

  Firstly: have the decimal separator ',' in a digital indicator is just for aesthetic purposes, you can always calculate using the value...

  (1) you can change the settings of the operating system (Win: settings regional aka regional Einstellungen). I do this for all my computers as it seems "natural" for me when working with scientists/measurement data

  (2) you can move LV to ignore the decimal separator system settings - you will find in the dialog box options...

  But when using properly formatted output functions you do not need to change any setting...

• Incorporate the binary string in the string spreadsheet file

  Hello LabVIEW wizards...

  So I use scripture to VI file spreadsheet to create a beautiful layout, tabs-delimited report of one of my programs for the acquisition of data file. In one of the cells in the resulting worksheet file that I want to put a binary string of all my control values so when you open the data file all the control parameters used for its manufacture are restored, but the string is hidden when the report is displayed in Excel.

  The problem is that the binary string flattened uses tabs and returns as part of its syntax the Spreadsheet File this VI to Write it's going in all directions. Worse yet, I can't unflatten chain when I open the file text because of "corrupt data or unexpected".

  If I concatenate the string flattened with quotes around it she is superb and is placed in a single cell in Excel, but when I open the file in LabVIEW that she is still several elements in the array. I've isolated the binary string using the file VI text reading and got a subset of the quoted string, but it still unflatten correctly.

  Essentially, I need to know how to get LabVIEW to pull a string literal full of special characters into a spreadsheet file and it unflatten. Any gurus what help you can provide is greatly appreciated.

  Thank you

  Jordan

  I suggest that you change the formatting of your chain shipped by replacing the tabs and returns with other characters that are not considered as commands by the spreadsheet functions. Without knowing how you represent your control binary values, I can't offer specific characters.

  If two non-printable characters exist which do not appear in the control data, it's easy: just find and replace tabs and returns with those characters.  If there is no character, then something more complex needs to be done for example to escape special characters.  Or create two subVIs - one to remove the tabs and returns before writing the string in the file and the other to restore after reading.

• 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.

  

• 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.

• How to parse a binary string

  Hi people,

  I read a binary string to a Sonic anemometer of campbell. It is transmitted via RS 232 9600 baud. The problem is the following:

  I read the entry stamp from time to time (all 300 ms). The outpit of the sonic is much faster (every 30ms). There is only a certain amount of stored bytes I've read. To get a correct value, I find 2-byte endpoint AA HEX and HEX 55. A complete sentence consists of 12 bytes 10 bytes each endpoint U8 values and 2 bytes. How to search for them?

  My idea was to see how many bytes, I read, convert each in a binary table and then show them as boolean table all together (see annex VI). It works but I can not find the expression just binary AA Hex and 55. And it is as interesting as the first column (bit 0) and last (bit 7) always remain 'false. ' I'm doing something wrong?

  So it would have been more useful if you would have posted the example that has been read data.  Because I didn't have everything I've done a few.  The attached VI will look for places where the hexadecimal byte AA then 55.  It then divides the sections of data using this information.  I wrote it two ways because I was typing this I thought of a better way that uses string functions to break the data into a data table.

• Ascii to binary string string conversion

  Hello

  I am fairly new to LABVIEW but now I connect to a device using a serial RS232 cable.  In any case I use VISA read to get the output of the unit, and I wanted the device to return the output to ASCII format.  He is able to do, but now I'm stuck.  Now, I'm trying to convert this string of ASCII characters to a binary string.  In other words, if my release was a "Medley" of VISA Read, I have to be able to get a string that was '0111000101101110 '.  Any help is appreciated.  Thank you.

  This does not make much sense, because "0111000101101110" would be "SB" and not "QN". You want to throw a conversion 'lowercase' too?

  In any case, here's a solution that works with any length of string.

  

  This seems quite complicated. In general, it is easier to work directly in binary strings rather than binary to ASCII format.
