• Excel 2010 and labview 2010

  I think that this may have been covered, but if anyone noticed all the differences in the properties of the ActiveX or methods in labview when working with excellent 2007 versus excel 2010? I know at one point Microsoft had changed a few things excellent 97-2003 "and instead select 'value' in your method, you must now choose"value 2". Is the real wait even for excel 2010? I am currently using excel 2007 at work and 2000 at home, and when I opened my code at home, my call nodes 'have the wrong son' still all required entries are correct. Same code on excel 2007; lot of son and the code will be run. I'm just curious to know if anyone has tried to use labview 2010 and excel 2010 together and made a work? I'm opening 1 workbook and wrote to 4 different excel sheets using Windows XP, excel 2007 at work and have windows 7 and want to use excel 2010 home and prefers no problem or to all the least know what are potential problems. Sorry if this confusion. I think it's the best way I can explain that I have MY head wrapped around it yet.  I do not want to write the same code twice for different versions of excel. (write and test at home, then re - write at work)

  This is an example of what I'm talking about

  Myke,

  While I don't have excel 2010 available to try and see, Microsoft (and MSDN) has a huge amount of information about calls in all versions of Excel.

  Excel 2010 development resources: http://msdn.microsoft.com/en-us/library/ee658205 (office.14) .aspx

  Excel 2007 development resources: http://msdn.microsoft.com/en-us/library/bb979621(v=office.12).aspx

  I hope that helps you start, because I don't have access to excel 2010. Let me know if it works for you.

  Kind regards

• Excel data in Labview counters

  I'm working on a project that requires me to read the data into excel and display this data using one of the numerical indicators of LabVIEW. I use Excel sheet Change.vi track to get data from Excel in LabView. However, I'm unable to display this data in a digital indicator. The question that I am running is that the data is in an array of strings 2D, and counters do not accept that numbers of unique value [I seek for dual-format]. Is it possible to access the values of individual table and display them with, say, a meter? I have 8 values of interest in table 2D.

  Thank you

  Michael

  Hi Michael,

  Here is an example of using the function of index table. I have a 2D array is read by a couple of functions of index table to display different values from him.

• Can't get bytes of CPU to read in LabVIEW * FTDI * Serial Communication *.

  I have trouble to get LabVIEW to display the bytes I send from a microcontroller with a FTDI chip.

  Specifications of communication are:

  baud-19200

  -8-bit word length

  -1 stop bit

  -no parity

  -no flow control

  I modified the demo of the chain of read-write of the here just reading the chip. I see that a few bytes have been read in the indicator "bytes read" but nothing appears in the buffer. Any ideas? I may have something hooked up wrong or something wrong in communication specifications

  
  

• Is there a way to select an area of some of the elements of a csv file and read in LabVIEW?

  Hello everyone, I was wondering if there was a way to select only a certain "box" of the elements of a .csv file in LabVIEW? I have LabVIEW 2011 and my main goal is to take two tables and graphs against each other. I can import the .csv perfectly and separate each line and each column to be his own, but I have a 8 X 8 but want graphic in the middle of 4 X 5 or something like that. Is it possible to extract a table without starting at the beginning and end in the end? Thank you in advance.

  Hi Szklanam,

  as a CSV file is a TXT file with a different suffix, you can read a number of lines in this file. For example, you can limit the number of rows in your table of resultung. To limit the number of columns, you must always use an ArraySubset, so maybe it is much easier to read the complete CSV file and select interesting places with ArraySubset...

• Data read rotation Labview via a cable line RS232 and USB converter series

  I have a program to read a string of data to a 2B Technologies Ozone monitor model 202.  The program does not come to the top with an error message, but every 30 to 40 hours Labview will turn my row of data.  For example, if a normal data row is 34.5, 37.5, 812.0, 934.0, 07/11/14, 11:52:38 and coma delaminated, then the problem is the reading (first digit) ozone layer displays the reference zero, then the seconds of the playback time will be moves in the spot ozone in the data file and the line will turn from there.  I tried to change the bytes being read to the Labview program and the many ways of emptying the buffer, but the problem is still there.  I have attached an example of data file in which the problem took place and a screenshot of my labview program.  I am a user of labview fairly new descriptive help would be much appreciated.  Thank you!

  When you use a termination character, do not use the bytes to the Port. Just wire a constant to the number of bytes that is larger that the largest message possible.

• import excel data to labVIEW, filtering and exporting to Excel

  LabVIEW dear specialists,

  I have about 2500 data each for acceleration and force stored in two excel columns of the worksheet as well as time data in another column. My problem is to purify my data of noise so I could generate thin sinusoidal signals for my thesis. I'm still new to labVIEW and I would like to ask for help to import my data from labVIEW, filter and exporting to Excel. Please help me. I enclose my data below. Thank you very much.

• View the Excel sheet in LabVIEW

  I have a series of files MS Excel 2007 (xlsx) I want to integrate and display in LabVIEW 2012 selecting them individually. Currently, the only way I can see the spreadsheet in LabVIEW is to place my ActiveX container on the front panel, then "select ActiveX object' followed by 'create a file object '. The Excel sheet then fills the ActiveX container and that is exactly what I want my face to look like. However, I don't seem to be able to 'Create a file object' programmatically using nodes and must manually bind each file to display my result in the ActiveX container. I'm sure I'm missing something and any suggestions on how to do this would be by program greatly appreciated - thanks in advance!

• How to randomly choose excellent data using labview.

  A very good day to all. I am currently working on a system that will be selecting whole number of together generated at random in number. If this is not possible, I would like to the system to be able to select the number of the set of numbers that have already been generated randomly from excel. kindly help me with the solution. To get clear, assuming I put numbers 1 to 10, I want a labview setup that will recover these numbers one after the other or with replacement without excel or auto generated. I know it's possible in matlab, but would prefer if possible labview.  Thank you

  More, otherwise all of the languages that I ran across were a rand() function returns a random number between 0 and 1.  Get some other range belongs to the programmer.  The usual method is to multiply by the beach, you need and add an offset to adjust the average.  For example, if you need a random number between 200 and 300, the formula can present themselves as "rand () * 100 + 200". "   If you need an integer, you can use the round function (who, it will remain as a float with no decimal pportion) or conversion (all).    All this is feasible and direct in LabVIEW.  Take a look: http://digital.ni.com/public.nsf/allkb/FCCDCD678EEF3A9186256D7B008054F5

• Audio reading of LABVIEW (with break and reverse)

  Im trying to build a VI that will play a pre-recorded sound, with the ability to pause, play backwards and go to any part of the audio data and continue playback. (Play in reverse would be a nice feature, but does not really need to be there). Once I understood the procedure, he will fit in with reading video and recorded the data display, so it must be fairly dynamic in the measurement of time of the loop, when added to the output buffer.

  I have what I thought should work (written in LABVIEW 8.6) only I find that the 'writing of audio output' vi is not as expected. My interpretation of the documentation for this vi is that when you enter data in this vi (with zero time-out wired in), he should dump these data in the output buffer and then return to the main program, then these data are playing. However, I find that this does not happen and that the vi takes at least that long to finish than it takes to read data. The rest of the vi is completed in less than a millisecond, then this is definitely the vi that takes all the time. It is causing the sound to be very clicky and sometimes don't even look like a sound vibration.

  I'm using the wrong screws? is there a better way to go to achieve this goal? The VI I wrote is attached. If the sinusoidal signal is set at 500 Hz, it sounds like the sampling frequency is a multiple of this not exactly why it works (Im). If I have the sinusoidal signal set to 501 or 510Hz for example, you hear the problem I described above.

  Just a suggestion.,.

  You could try the windows media player activeX control.  Just load the file you want to play using the nodes property of the activeX control and it does the job remaining.

  I am juice tests the vi you attached and will post back if I have ideas.

• Insert rows Excel spreadsheet using LabVIEW

  Hello

  is it possible to get each row of a table in a spreadsheet different, for example the 1st rank in the 1st sheet and so on using just EXCEL ADVANCE live

  for example the 1st rank of the 1st worksheet

  

  Hey achfire,

  I made a few changes to your code, and it seems to work now. In General, we do not want open and close references or files within a loop. Instead we can open the file once, read/write to it in our loop and then save/close it when finished. I also removed the function array index, regarding the loops can auto-index loop bounaries. (That also prevent us from having to wire a number of iterations in the Terminal "N".)

  Let me know if it helps!

• structure of event using read indicator labview

  Hello
  I would like to be able control the light using the structure of the event.
  I use with block serial reading and analyze the string. When he acknowledged the string must change the State of the LED each time.
  Please let me know if it is possible and how I can exec who?
  Please find attached the file VI.
  For example I would like it when the string "Door open!" is displayed it must change the State of the LED.
  Thanks for any help,

  This isn't to make the event Structure is used.  An event Structure is used to capture GUI events, as a user presses a button or changes the value of a control.

  If you want just the value to toggle, using a shift register to store the current value.  If you find the right chain, toggle (using the NOT function).

• I can't Omega PX4200 pressure transducers where I can get a reading of Labview

  Hello

  I am a new user of LabVIEW, and I currently try to wire in a 4-20mA Omega PX4200 pressure sensor in an NI USB-6009 Data Acquisition device. I have sources of power like a P SOLA SDN 5-24-100, and I use a 3-wire system. I have the black wire going to SOLA a +, the ground wire to the GND on the NI USB-6009 case and the white wire going to the AI0. Currently, I am unable to generate a significant signal either in solution of measurement and Automation Explorer or LABVIEW Signal Express 2010.

  If anyone has an idea on what I'm doing wrong, just reply to this topic.

  Thank you

  Dev

  The USB-6009 measure the voltage.  The pressure transducer is a current signal.  You must add a kind of conditioning of signals.  At a minimum, you must use a resistor to the terminals so that you can convert the signal 4-20 mA, the transducer is a tension.  To convert a signal of 20 MA in 10V, you would need a 500 Ohm resistor.
