How to name columns in "Write LabView Measurement File" Express VI

Hello, I am inputting two signals into the "Write LabView Measurement File" Express VI, and although the data is recorded correctly, there is no separate header for all the y-values (I only get the X-value column labeled: X_Value), and then there is a "Comment" field right next to it. How do I name these y-value columns so that the header appears alongside the X_Value tag? Thanks.

I don't want to read from a LabView measurement file. I'm saving in a file; that's good enough. I just need to save it in headed columns. Any suggestions?
Here's a test of the program with two random data inputs, and a picture of the output.Message Edited by Doagie on 06-13-2005 01:22 PM

When I place a 'write to measurement file' express I get an 'Error in prop page construction: Control Label: Streaming' Using Labview 8 on XP. Any ideas?

When I place express 'write to measurement file' I get an error
'Error in prop page construction:
Control Label: Streaming
Couldn't find control/constant on the instance.'
Help!!!!!
Please.
Regards
Derek

The error happens as soon as I place the symbol. The symbol is there and the properties are all accessible, but will not run.
I enclose word doc with error messages on.
Many thanks in anticipation

About "Write LabVIEW Measurement File" Expres vi. I got problems with ENABLE function

It is a traditional DAQ problem. I acquire some data and I want to write it on file only if voltage value is greater than a constant value (I used "Comparison" Express vi to do comparison). This mean that enable must depend on the result of comparison. I dont want to write unuseful data. What happens is that if the last scan is greater than the threshold, all data is written; if the last scan is smaller, all data is not written.No matter if intermediate scan result is zero or one.

There may be a bug in the comparison VI. I experimented with simple waveforms (0,0,1,0,0) and (0,0,1,0,0,1). I used the greater than with a cut off of .5. I also set the VI to output one answer for the entire sample.
I saw that the VI outputed 0 for both data sets. When I used the property page to invert the input, both sets outputed 1. I believe that if you just inverted the output of the comparison VI, you will be fine.

System time in Write TO Measurement File

Hi, everyone. I'm Sorin.
I use a DAQ 6210 in Labview 8.2 to aquire some analog data at 1 sec,and i have 2 questions, please:
1. I need to record the data into a file .lvm, so i use "Write TO Measurement File" module with one column of time (X axe). But this time is relative, and i want to be system time instead. Is there any way to resolv that ?
2. Also, in my Waveform Chart i put absolute time because i couldn't find system time, though i need it. How can i change that ? Although, once i played with charts, and i succeeded to see system time, but now i can't. And i'm sure it wasn't complicate.

Hi Sir
I had similar problem. I tried to write to a measurement file with absolute time, instead of relative time here I got.
Also, I want the format to be sth like this 13/09/25 18:16:01.
Could you help me?
Thanks

Binary file is greyed out in Write Measurement File express VI.

I am running labview 8.2 on Fedora 7 Core. I have also installed it on an earlier version of fedora that was in line with the supported red hat distribution. The problem is that when I try to use the Write Measurement File express VI, the binary file option becomes greyed out after the dialog box opens up. It is present for a second but it is impossible to select. When I have tried bringing over a vi written in Windows (where the binary option was available), the option is also disabled. I am trying to avoid writing the file out in lower level code since I want to use the auto file name generation available under the express VI. If any body knows a workaround or has some sample code that writes out a new file for each measurement with the date and time in the filename let me know.
Thanks

Hi Ikiller,
Is this still occurring?
Could you please provide a screen shot to show the behavior?

How to read from and write into the same file from multiple threads?

I need to read from and write into a same file multiple threads.
How can we do that without any data contamination.
Can u please provide coding for this type of task.
Thanks in advance.

Assuming you are using RandomAccessFile, you can use the locking functionality in the Java NIO library to lock sections of a file that you are reading/writing from each thread (or process).
If you can't use NIO, and all your threads are in the same application, you can create your own in-process locking mechanism that each thread uses prior to accessing the file. That would take some development, and the OS already has the capability, so using NIO is the best way to go if you can use JDK 1.4 or higher.

How do i create and write to an xml file?

I know there are methods to create nodes and such but I am not at all familiar with xml. Isn't an easier way just to use the File class to create the file and use the write method to write to the xml file? Thank you.

Write to measurement file help

Hi,
I am a beginner. I am working on a VI.
But have some problems that I couldn't solve.
Here is the VI attached, I get on the output the positive and negative peak values which I then write to a mesurement file.
But now I just get my last values of positive and negative peak in the measurement file.
But I there were different values before that last values also. I want to save all the values, or every time that values changes on postive and negative, I would like to save all values to a file.
Would be great if someone can help me with it.
Regards,
Raj

If you did the TDMS file your self (not use the express VI). Then you could specify the group to write into and the channels. It sounds like you want to add new channels each time you acquire a set of samples. Look in the example finder (Help->Find Examples) for TDMS Write Triggered Data.vi. It looks like a decent example to get you started.

Problems with write to measurement file

My VI doesn't seem to write my signal properly when writing is enables.. however, if i change the "Write to measurement file" Express VI to a Write to Spreadsheet function, the signal is written correctly. From what I understand in previous discussions, there is a bug associated with enabling a write to measurement file, so is there a way to enable write to spreadsheet instead of using the express VI or is there a way I can bypass this bug?
Thanks,

Analog test and collection.vi ‏700 KB

This is my second program ever written, first in matlab, so I am very new to the field. So why I choose one way over another I have no reasoning, all I know is that it works. I am collecting electromyography analog signals, with a range of +/-5V.. the "bad" writing with write to meas file is that I am getting a flat signal (range between -.01 to +0.01, give or take).. where when written with write to spreadsheet, the signal has proper voltage range and normal frquency and amplitude characteristics seen in EMGs.
I tried using a case structure for the write to spreadsheet, however it only writes the buffer size during continuous sampling. I need it to write the entire time the boolean (enable button) is true, also the enable button is operated as switch when pressed.

How to read columns of a Microsoft Excel .csv file with LabVIEW?

This should be simple. Any ideas on how to read an Excel file with csv extension using LabVIEW?
Thanks!

Use the Read From SpeadSheet File.VI which you can find on the FILE I/O pallette.
"Read From Spreadsheet File
Reads a specified number of lines
or rows from a numeric text file beginning at a specified character offset and
converts the data to a 2D, single-precision array of numbers. You optionally can transpose the
array. The VI opens the file before reading from it and closes it afterwards.
You can use this VI to read a spreadsheet file saved in text format. This VI
calls the Spreadsheet String
to Array function to convert the data."
The CSV file is essentially a text file which uses commas as delimiters in the files structure.

Attach labels for write to measurement file and graphing

I am currently having alot of problems with attaching labels to double type of wires and changing the label attached to the dynamic type of wires. I want the write to measurement file to have the correct headings but the current headings for the columns are displaying untitled or change the heading for the dynamic type of wire. I attached a picture of the program and I would be very grateful if anybody knew how to change these headings.

Try this VI I made. It takes in a Double signal and a string, names your signal, and outputs it as a Dynamic Data.
I used this with the Write to Measurement File without any issues!!!
To name a Dynamic Data Signal, use the Set Dynamic Data Attributes VI found in Express > Signal Manipulation
Hope this helps,
Cheers

Improving Write to Measurement File Rate

Hello again everyone,
I was wondering if I could once again get some help with my VI which is dealing with data aquisiton, display and logging. I'm attempting to display and record all the data that is incoming serially from some external ADC boards. The data is received at 500Hz and I am trying to currently record this through the use of Write to Measurement file, however i'm finding that I am not recording all the data that is captured into the file. When I tested this code I found I was only getting a recorded sample rate of about 3Hz... I'm looking to reach at least recording the data at 50Hz minimum, however i'm having trouble figuring out how.
I currently have a global loop with a delay of 100ms, however reducing this increment did not noticeably increase the rate at which the data is recorded. I suspect it is due to the time taken to carry out everything within the loop, however I don't know how to improve this, using a different structure perhaps? If someone could take a look at my VI and give me some pointers on how to improve the cycle rate that would be awsome.
Also, I find that the display is quite laggy in displaying the incoming data. Again this wasn't improved by changing the delay in between the loops or selecting the synchronous display option. The delay in inputing data at the ADC and seeing the result on the screen was somewhere around 1 second!
Any help would be greatly appreciated as I don't know how to sort this problem out.
Thanks in advance!

Serial read v2.2.vi ‏136 KB

Hi Stirling,
I don’t think it’s a problem with the Write to Measurement
File.vi. You need to have a look at the VISA Read.vi. You are reading 5K at
every iteration of the loop and that could probably be causing the delay. A
great way to troubleshoot this would be to turn on highlight execution.
Also, you should consider using the Array to Cluster.vi and
the Convert to Dynamic Data.vi in the Write to Measurement File.vi block. This
shouldn’t effect anything; just a suggestion to take advantage of LabVIEW functions.

Extending decimal points on timestamp for write to measurement file .vi

Hello Everyone
Currently I am collecting a bunch of Fieldpoint Channels in LabVIEW (about 190) which is a lot of instrumentation. Right now we want to be sure the computer can keep up and read all of the channels every second. To test this theory I want to use the WTMF to get a timestamp for every channel (seems to be the easiest way).
While reading the file I get like 5.68 so two decimal places. I was wondering if there was a way to get a more accurate time reading down to the millisecond. I know this is three places after the decimal point, but I was hoping I could extend this to 5-6 places past the decimal point.
Usually when saving data I use the write to spreadsheet with one time column and can just format the readings through that, but for some reason I cannot figure this out with the WTMF
If there is any input to check these time differences besides doing the above, that would also be appreciated.
Any input would be amazing.
Thanks so much
Tanya

Hi vaib,
as i said already here, http://forums.ni.com/ni/board/message?board.id=170&view=by_date_ascending&message.id=332115#M332115 i think you can´t stop the writing process. If you start them, then you have to wait til the vi is ready. To measure the time you can use the "Tick count" function. See the attached picture.

How many channels can I write in a same file with the Write Data Module (Dasylab 12.00.00) ?

I would like to write data from a large number of channel (up to 128) in a same file. Using the write data module, I have up to 16 channels only ! The only solution I found is to save data in 8 different files... Is there any solution to solve this problem ? I use DASYLAB V.12.00.00. Thank you

How to pass column header as a parameter in Validation Expression (APEX4.0)

Hello
I created a new Page validation in APEX4.0 ( not 4.1 ).
(1) Type : Function Returning error text
(2) Validation Expression 1 :
begin
return validate_name ( p_c=> #COLUMN_HEADER# ,p_c_value=> to_date(:p26_LEAVE_FROM,'dd/mm/yyyy') );
end;
note: the validate_name is an oracle pl/sql procedure which takes two input parameters ( column header name and actual value ) and return a specific error message ( to that column ) or NULL.
(3) In the Error Message section, I left Error Message blank ( as the app ignored the mssage but used the one returned from the above function)
However, I chose "The Error display location" to be inline with field and notification" and Associated Item to be "p26_LEAVE_FROM".
My question, it worked if I hard coded the actual column header "LEAVE FROM" , but it didn't work if I used the above #COLUMN_HEADER# in Validation Expression. Can I avoid hard coding as the column header might be changed one day. Is there a better way to deal with multiple column validations with different error message for each column ? It seems that I will have to create similar page valiation for each column to be validated.
Thanks for your advice.
