Writing in the spreadsheet in a loop file?

• Writing in the spreadsheet with the queue

  Hello

  I am a beginner with queues and I have a few questions.  I have attached a simple example of code that I wrote to better implement a consumer who can queue data and write on a worksheet after running the code.

  First of all, I noticed that the queue still has residual remaining after the code ends.  It then writes this element to the file to run the vi.  I can't figure how to get rid of this element.

  Second, anyone have any suggestions to improve this code?  I've been playing with it for quite some time and I finally got to work like that, but it is certainly configured differently from the other examples I've seen.

  Thirdly, I am reading the number of items in the queue, but the two in the loop of the producer and the consumer, told me that there is no element.  How can this be?  My output file seems to work and I certainly put items in the queue.

  Finally, in the future I'll use data from the queue in two places.  Here I've implemented a notifier to do the job.  This is the best method?

  Thanks for your help!

  The reason why you do not get the last element of the queue (at least not until you restart the VI) is that you have your automatic indexation tunnel that collects all the data to send to the writing on file SS service cable for moving to register.  So this last piece of data from the queue to get into the shift register, but it is not getting into the 2-D chart by the tunnel of automatic indexing up to the next iteration of the loop.  When you rerun the VI, as the shift register is not initialized, it is already there and became the first point of your next data execution.

  Why did you put the register shift in?  Just remove and just use the tunnel of automatic indexation.

  I don't know what you really want to do with the 2nd loop to say if the Notifier is correct or not.  But if you do not want to lose data in the other loop, then you need to use a second queue and have your producer loop enqueue data in the two queues, a queue for each consumer loop.

  With regard to the elements draws in the queue, seeing how your code is configured, the queue will almost always empty because the dequeue function will be ready to pull out the element immediately after the enqueue function puts in.  Unless you have your loop producer much faster than your consumer loop running, you will not see a build up of the elements.  (Try putting an expectation of more of 100 msec in your loop of consumer.  Then you will see elements accumulate in the queue.)

  I don't know why you put the spreadsheet feature writing after the loop.  Normal use for queues in an architecture of producer/consumer must transmit the data to a separate loop that contains the functions write file.  This way he can work at his own pace, but write the data and make sure that you do not lose it.  As you have now, if your code runs a long time, you may run out of memory when at the tunnel of automatic indexing table becomes too large.  And if your application crashes before you complete it with your stop button, then all data are lost because you did not it writes the file.

• Write to the spreadsheet file

  Hello

  I try to write in a spreadsheet file.

  There are two things that I try to do what does not the current .vi.

  1. ask a name of file to outside the while loop. For the moment, this happens inside the while loop.

  2. Add to the file (by setting true) does not work as each time the while loop is iterated in this example, it asks me for a new file name. Shouldn't it just add to the file without having to ask a new file name on each iteration.

  Thank you

  If you do not specify the path to the file and then writing on a spreadsheet file asks for the file.  That just the way the function works.  If you go to the range of advanced functions of file, you will find a file dialog box function.  Put outside your loop and pass the path resulting in the loop and writing in the spreadsheet file.

• Problem with writing in the new file every day, error #1

  Hi, I have build a vi that writes data measured for each second of the file. This vi will be used for the acquisition of long-term data and I want to write the data to a separate file every day, else the file becomes

  very large. The vi is supposed to work like this, first set the folder to save it and then start logging with the "datalogon" button, first write the column names in the file and after that write data

  every second. If the date is the same newspaper, data, if the date is not the same write the new file name, write the column headers and write the data again every second. The date is used as the file name.

  This work is quite good only at the beginning of the vi I get the message "error 1 occurred open/create/replace the file writable spreadsheet String.vi-> write to the spreadsheet (string) .vi-> NHR file -

  SerialDaq - 03 APR 2013 .vi. I did some tests and it seems that in the first or the second round of the loop, the path in the annex is ' file name:------"and not drive:- and this seems to be caused by the fact

  that I first write the column headers, and then the data (if I write only the data of the problem does not occur).

  So I (think) for what is now the problems but don't don't know how solve it, I would appreciate it if someone could help me with this.

  Regards, Martin

  I made the change you mentioned and to my surprise I got the error message and also, with the vi you sent, I took look at it and found that:

  -If I first enter the "folder to save the file', then run the vi and then press on the" data connect "I don't get the error.

  -If I first run the vi, then enter the folder ' save file to "and the hit" the data log on ' I get the error.

  I also tried with the vi original (without the connection shiftregister in the case of false and init for removal) and which gives the same result as above. If I get the

  error message and choose stop the vi, start the vi again once I don't get the error because the folder in which the file is entered. This issue appears only when there is no file «»

  to save the file "in the dialog box.

  While I'm writing this I realize that "folder to save the file" is outside the while loop so only executed at the start of the vi is maybe I have to put it inside the while loop? A tried

  This and at first, it seems that the problem is solved, I don't get the error message on my screen, but it still appears on the error handler in another part of the vi (visa series).

  Oh, Yes. The 'name of the resource visa' and 'file to save the file' are both outside a while loop and are only read at the start of the vi, at the moment they have not a valid

  the error value is generated.

  Problem solved, thank you for your comments!

• Create several virtual machines on Vsphere multiple using the spreadsheet V2

  After much tinkering with the orginal VM deployment script, I brought a lot of improvements over the old.  I'm still learning my way powercli... It is not a pretty looking code, but it does the job...  I hope it helps

  The script is designed for a windows model that has two hard disks and two card WLAN.  Virtual machines are configured after their deployment to suit the needs of the customer.  You should be able to modify the script to fit your needs.

  The script file and sample xls is attached.

  Features:

  1 deploy VMs of template file and comstomization using worksheet

  2 customization of VM after the deployment of the VM

  3 multi-thread

  4 deploy VM on vSphere servers.

  5 creates the log file

  6 create notes, the date and the user who made the VM VM

  Columns of the worksheet: (the script is designed to go from line 6.  You can change it in the script)

  The virtual computer name. Host name | CPU | RAM (GB) | DISK2 (GB) | DISK3 (EN) | Nic1 connection | Name of the model. Data store | Notes

• Write to the spreadsheet file (how to start new lines)

  I'm reading signals from a hardware device and try to write it in several columns using Scripture in the spreadsheet file every few seconds.

  My problem is every time a new signal comes in, my program seems to overwrite the previous signal when writing to file, when (say after 2 minutes), I go to check the written file, it shows only 1 row of information. How can I fix?

  Part of my VI and the output file is attached.

  If the program segment shown in your picture is inside a loop, then the section header write overwrites the file each iteration of the loop.  So, you see only the data for the last iteration.  Solution: Move portions header to write and write the names of channel out of the loop or put them in the case of structures that run only when you want a new file or new channels.

• Incorrect writing to the file timestamps

  Hi all

  I wanted to familiarize yourself with writing data and associated timestamps in a file to verify the rate at which samples are played back in my system. As a little test I wrote a simple VI that travels 5 times and creates 5 sine sampling points. Each point has its timestamp captured and converted to seconds and fractions of a second. After the for finishes in loop iteration it writes the data of sample (line by line) for every 5 samples with their associated timestamps.

  I imposed a 1ms delay for each iteration and hoped to see the consistency between the timestamps of the consecutive samples but sometimes they are very or even identical to the previous timestamp which doesn't make any sense for me. I tried with wait times and it seems to be more precise between samples, but this result is intriguing.

  Example:

  31.209159       0
  
  31.209159      84
  31.209159      91
  31.224784      14
  31.224784     -76

  I chose not to use custom file VI writing because I had the same problems and thought that it could have better results.

  Hoping someone can clarify it or show me where I'm wrong. I have attached the VI below.

  Thank you.

  If you are using a hardware device timed, as NO hardware DAQ, you then get accurate timestamps. Everything else is a limitation of the Windows operating system. You can always switch to LabVIEW RT if you need more specific expectations.

  Hi weitong,.

  By default, Excel expect point comma as delimiter in csv files. Change your constant from tab to a semicolon and everything goes well...

  Or open the file using the dialog box import Excel and tab as a delimiter in step 1 of the wizard.

• day: hour: min:second of logging in a writing on a spreadsheet file

  I need to write a timestamp date time format: day: min:second (25:13:23:56) in a spreadsheet file.   Ideally using the output of ' string of Format Date/time ' and enter a 'table to build' there it goes into writing to the worksheet.  The only reason why it's required format is because I already have a program of scientific data logging 10metres upward and running.  It uses the timestamp of a Datetime.vi who takes the form of integer 132356.

  Thanks in advance for your help

• Change the decimal point by point in the writing of the measurement file

  Hello

  I use writing to the extent of the vi file to save data. I can't read the text file in Matlab, I guess that is because the decimal separator is a comma.

• Is there a file size limit when using read the spreadsheet file?

  I'm reading in a large file, approximately 52 MB, 525600 lines with 27 fileds in each line using "Read SpreadsheetFile.vi". I then explore table 2D-999, which represents bad/no data in this area and the total number of fields with-999 in there. All works on 3 months ' worth of data. The program is giving me a memory error output and stopping in case reading takes place on the file of the year a large. So my question is that the reading of the spreadsheet file has size limitations? Is there a better way to do it? Thanks in advance for the help.
