CF6004 Time Stamp log into file

I am trying to attach the time stamp to the data log that I obtain from
the NI CF6004. Is there an example that I can look at? I would like to
print <Time stamp> <value> in the file. I am sampling
for multiple channels but one sample value at a time.
In addition to this, I wanted to generate a plot displaying the value
of multiple channels with respect to time values. Is it possible?
Thanks in Advance,
Karthik

Hi Karthik,
Since you are simply taking a single sample at a time and logging it to
a file that should be relatively easy. Essentially when you
create a file you decide how to format the data. In your case you
may want to log everything as ASCII data. If that's the case,
then you will need to simply use the Get Date/Time String and
Concatenate that string with a Number converted to a Fractional
String. You can see how to do this below:
I also made sure to make this tab delimited so you could read it in a spreadsheet later.
There are lots of ways to do what you are trying to do, but this is just the way that I chose.
Have fun programming the rest of your application,

Add time stamp array into first column of text file

I am writing daq output to a file by using array to spreadsheet string vi then write that to a file but I would like to add a time stamp array into the first column of the text file. How do I do this?

When you use a DAQmx Read, you have the option of returning a waveform data type. This includes time data. If you were to use this and either Export Waveforms to Spreadsheet File or Write Measurement File, this would included. To stick with the regular Write to Spreadsheet File, you would have to create an array of timestamps yourself based on a start time and the sample rate of the DAQ. Then you would convert this and the data array to strings and use the string array type of Write to Spreadsheet instead of the DBL type.

Customizing Time Stamp In Receiver File Adapter

Hi,
I am working in a XI to file adapter scenario.
The default time stamp in receiver file adapter is yyyyMMdd-HHmmss-SSS.
I want to time stamp as "ABC_MM_DD_YYYY_HH_MM_SS".
i searched SDN,but not getting an end to end approach.
Like...I developed a UDF ,but when I map it to receiver root node..I am getting error.
Please help.
Just request for a step by step procedure.
Also,ASMA is not v clear to me......
Plzzzzzzzzzzzz help!!
Regards.

Hi sriparna,
The timestamp used by the File Receiver Adapter is a default pattern, to achieve that you have to use a UDF in the middle of the MM and set the receiver file name with the ASMA, read this for further information:

How can i add a time stamp to tdms file?

I want the data and the time for the tdms file generated?
how can i do that?
should i cinvert .tdms to .lvm and use the data storage option or excel add on option for .lvm file created?
cant i directly have the time stamp for tdms file generated?

How are you acquiring the data in the first place? That will matter in how we want to approach this.

\n is not working by the time writing text into file ...

Hi,
I am reading each line from file and writing into another file ...
It is writing continously in the file even if i use \n for new line ...
Why "\n" is not working by the time writing text into file ...
Here is my code:
import java.io.*;
import java.net.*;
import java.util.*;
public class Test11{
private BufferedReader data;
private String line=null;
private StringBuffer buf= new StringBuffer();
private BufferedWriter thewriter=null;
private File file=null;
private FileReader fr=null;
private String inputLocation="c:\\test14.txt";
public Test11(){ }
public void disp(){
try {
file=new File(inputLocation);
fr = new FileReader(file);
data = new BufferedReader(fr);
while ((line = data.readLine()) != null) {
buf.append(line + "\n");
String text=buf.toString();
thewriter = new BufferedWriter(new FileWriter("c:\\test15.txt"));
thewriter.write(text);
buf=null;
thewriter.close();
} catch(IOException e) { System.out.println("error ==="+e ); }
public static void main(String[] args) {
Test11 t=new Test11();
t.disp();
System.out.println("all files are converted...");
I used "\n" after reading each line .. i want output file also same as input file ... how do i break each line by the time writing into text file .. "\n" is working in word pad but now working in notepad ... in note pad i am getting some thing like rectangle insted of "\n" ....
Any help please .....
thanks.

\n works just fine, and every text editor in the world except Notepad understands that it is supposed to be a line-ending character. You don't have a problem, except in your choice of text editor. If somebody is forcing you to use Notepad then you'll have to output "\r\n" instead.

I have to tell Firefox that I am logging in from "home" every time I log into Facebook. Firefox will not let me unclick ""Send me an email" under Login Notifications in Facebook "My Account" settings. Why? (to both questions)

It started last week - I normally use Chrome to play my games in Facebook - but I started getting "Sorry, this feature isn't available
right now"..... When I used IE..... no problem - a friend said to install Foxfire, which I did, but I made the mistake of having my bookmarks and whatever transferred from Google as it is the browser I used most often and it has all my bookmarks, but
now it does the same thing when I try to log into Facebook. - I have no problem with any other website. I deleted both Google and Foxfire and tried to start over - I cleared History and checked all the boxes hoping that this would help - but it did not.
I can't understand why I can get in with IE, but not Google or Foxfire. Do you have any suggestions.......
On Friday, it started working again - and everything was fine. But on Sunday evening I ran the History Clean in Google and when
I went to log back in, I couldn't and got the same "Sorry" message and has stayed this way since.
I ran a Norton scan of the entire computer, a Hitman scan, a CCleaner scan, ... all to no avail. Problem still exists.
I tried to run a restore program prior to the problem, but I am getting error messages like mad.
there has been two Windows Updates in this time frame and I don't know if this has anything to do with it or not - but my Restore program does not work.

Transfer time stamp from text file into MS Access thru Labview

Hello everyone,
I am Cruz; Long time listener, First time caller.
I am currently monotoring data being collected by an oven. The data is stored in a text file. I am using Labview to take the data from the textfile and place it in an MS access DB for manipulation. The first three columns of the text file are the time stamp of data. When i transfer the data into Access i cant get the first three columns to display as a time stamp. Can have some pointers on what how to get the first three columns to display correctly.
Additional info:
the text file is a 1D array that gets overitten with every new mesurement tanken. the transfer to Acces is to not loos any of the information and to better manipulate the data into forms and such.
Running Labview 2010
attached is code and text file.
Any help is greatly appreciated.

Your first mistake is reading the file as DBL. Your first three columns are obviously not numeric values. Did you ever look at the output array? Read it as strings. Second, you would need to combine those first three columns to create an actual time stamp before you write to the db. Unless of course you have one column for date, one column for time, and one column for AM/PM. I would not recomend that type of structure in the db.

Insert time stamp in ASCII file

Hi all!
I am trying to log data values from several channels (so far 4) into one ASCII file including a time stamp in the first column.
The goal is one file that contains one time stamp per row (in the first column) and one column per channel. It may looks like this:
TIME Ch1 Ch2 Ch3 Ch4
t1        a1     b1     c1    d1
t2        a2     b2     c2    d2
I want to save one row (time stamp and 4 channels) each minute as above into the same file. Nice would be to creat a new file each day.
Problems:
1. Using the "Save to ASCII/LVM" step: How can I get SignalExpress to insert a time stamp in the first column of each row?
    I have no problem inserting the 4 signals that generate me one column per signal. And using "Overwrite once, then append to file" I get one file for all signals.
    Any idea how to insert a time stamp this way? Or how to creat a new file every 24 hours?
2. Another way I tried is to use the "Recording Option". But how can I get all the four signals saved in one file?
    After the DAQmx acquisition step I process the 4 channels individually (one scaling step and one threshold step per channel - because of different factors per channel).
    Activating the Recording Option (which would generate a new file every 24 hours, but not starting at 12pm each day...) I get 4 single TDMS-files (and their corresponding tdms_index and meta.txt files),
    one file per signal I am recording. I assume this is because they are 4 individual signals I'm recording and not a group of signals. Can I group individual signals together?
Thanks for your help
SSC
PS: I work with SignalExpress 2.5 and have a NI USB-6210 connected.

In the recording options tab you can set a stop condition to be 24 hours of data. And then select the "Restart Log Automatically" option to start logging for another 24 hours. You can also configure the logging to auto create an ASCII file once logging stops. With this configuration an ASCII file will be created every 24 hours. To enable ACSII file generation, select Tools>>Options.. And then set "Automatically export log to ASCII file to true".
I believe that you will get one ASCII file for each TDMS file. If you are logging 4 channels from the same device you should be able to log the entire group which would allow you to get only 1 TDMS / ASCII file.

Time Stamp format from file problem

Hey there,
I have a pretty peculiar problem. I'm working on two PCs right now, one is my private laptop running on Windows 8, and the other one the PC at my workplace, running on Windows XP, but on the same version of LabVIEW. I use this method to save the time and date to a tab delimited .txt file. Then later, with another VI, I read the date and time written to file to reconstruct the time stamp. I've noticed that dates written to file from my workplace differ from the dates written from my private PC: in Windows XP, there are "-" separating the day, month and year. In Windows 8, it's "/". There are other differences (see pictures). So naturally, when reading from file using my VI, I can only read on my private PC files (or at least dates) written on my private PC and vice versa, I can't read files written on my private PC on my workplace PC. Can anybody tell me why there's a difference in format, or how to write the date uniformly so I can read it on any PC, or how to read both formats?
So this is the method I use for writing the time and date (the subVI only inserts a certain number of TAB characters).
This is what it looks like on Windows 8
This is what it looks like on Windows XP
This is the VI (attached) I use to read the time stamps (the first row actually contains the time stamp in HH:MM: SS format for a whole bunch of measurements).
Have a nice day.
Solved!

I would suggest using the ISO-8601 UTC format.
The only limitation is that the string value is in reference to GMT.
The conversion of the string back to a timestamp will present the date/time on your front panel indicator as local time.

Now is the right time to use %^<%Y-%m-%dT%H:%M:%S%3uZ>T

How to write time stamp to a file

Hi,
I'm using LabVIEW 8.2 and for my simulations purpose I've to store my data with time stamp (seconds having 6 digit precision ) in a text file.
I'm using get time vi to get the time of the host computer on a 6 point precision (which I've attached also). My problem is I'm unable to convert this time stamp into string which can be written to text file directly. I would prefer to avoid the "unbundle cluster" which gives me individual elements (like seconds,date,time,year,day of the year, etc) and them convert each of them into a string.
Looking to hear from any one of you soon,
Regards

Hi Roiht
You will never achieve 6 digits precision with the "get date/ time i seconds function" Perhaps 1 if you are lucky. But you can convert the time to string using the "format data/time string" function. You find it in the same palette as the other time functions.
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

Need to change Date/Time stamp on jpeg file

I combine images into panoramas using PTGUI. The problem is that the output image file is date stamped as the time that I created the image. I really want the date/time stamp to be the same as the images that go into the panorama. I cannot find a way in LR to change this.
