• Write to the file of measurement with a loop For using the value of the dynamic data attributes

  I looked and looked, but couldn't find a solution for this.

  I currently have 15 points of different data that I try to write in an Excel file.  I have all combined in a table and lie with the function "write into a file position.  However, the column names are always "Untitled", "Untitled 1" etc.  I then used the function 'Set the Dynamic Data attributes'; but for this I have to do 15 different functions "set data dynamic attributes.  It was suggested to use a loop with the function 'Set the Dynamic Data attributes' inside of her, but I can't find how do.

  I have several arrays consisting of 15 different values for 'Signal Index' 'Name of Signal' and 'Unit', but also a unique 'get Date/Time In Seconds' related to 'Timestamp '.  The problem is that the error I get when I try to connect the output with Scripture at the entrance to measure file:

  The source type is dynamic data table 1 d.  The type of sink is Dynamic Data.

  How can I fix it?  I have attached a picture of my installation; Sorry if this is gross (I'm new on this!).  Thank you!

  It will get rid of the error, but it is not quite correct. What you need to do after that is to click on the output or the tunnel entry and select 'replace with the shift register. In addition, the array of values that you have wired to the Signal Index is wrong. Arrays are 0 based. Just wire the iteration Terminal here. And, finally, take the size of the table and this connection to the N terminal are stupid. Don't wire nothing to this.

• How to record a fixed time of dynamic data interval when acquiring continues?

  Hi, maybe someone has an idea how to solve this problem:

  I do the continuous acquisition of dynamic data and when I see something interesting, I would like to save some data (i.e. the last 90 seconds). I guess the first step is written data in a table? I can set up the table so that it always contains just the last N seconds (or last N points, discard the rest as the measure of the loin) so I can then save this data, for example by pressing a button (possibly without stopping the .vi, or maybe just a break it.) This last step is not necessary)?

  Thanks for all the suggestions!

  Hi Tomaz79,

  You can generate as a black box on an airplane. You can initialize an array with the size of your 90 s write all data in this table by crushing at the specified index. With Quotient & rest, you will get the correct index for the next value. If you find your compelling value, you can be sure you'll get the last dry 90.

• The values of date time values are not complete

  Hello

  I'm experimenting with time values. During my interview, I have values such as:

  Huisnummer: {Onzeker, 12 van 01/01/01, Onbekend van 01/01/02, Onzeker van 01/01/18}

  The language I use is the Dutch, but the year is represented by two digits. I need to have four digits. There is a configuration setting that can be used for this? If Yes, where can I find it?

  Thank you!

  Han

  
  

  
  

  
  

  The display format of the date in the determinations of the Web values can be set in the configuration application.properties file. See this article in the OPA Developer's Guide: http://docs.oracle.com/html/E48376_01/toc.htm#Technical%20Reference/Config_Files.htm#application.properties

• Concatate Date and time values in a form and don't insert

  I try to combine a date and value of a time value to a form in a datetime value submission and then insert it into a table of 8 SQL server data.

  Here are the formats

  Date: 07/03/2013

  Time: 20:07

  So somehow, I need to concatate these 2 elements and then insert the value combined with a SQL server 8 data table. (Datetime data type).

  The inserted value should look like this

  07-03-2013 20:07:00.000

  No help my brothers dear cold fusion?

  You probably want to use ParseDateTime to transform your two strings (concatenate them) into a date object.  See http://www.petefreitag.com/item/569.cfm for a useful example

• How to store a timer value

  Hi guys, im fairly new to all this labview, so I apologize if this is a silly question, im using an elapsed timer, I got a signal when it is greater than a constant, it resets the timer that gives a value of 0 for a defiler, when the signal is in the range the timer shows time elapsed ontill the signal falls out of scope indicating 0 new ,

  If im trying to get the last value before reset has been exacuted, or more time between the two, so that I can send the value for futher as RPM calculations

  Thanks for the tips!

  my head hurts!

  Hi Vadajooz,

  You can use the convert to Dynamic data VI and configure it to convert a single scalar value. This will give you a floating point number that you can enter for the comparison group.

  Kind regards.

• Track of multiple graphs on a single diagram of waveform with dynamic data types

  I'm putting multiple charts on a single diagram of waveform and data contract error. I was wondering if it has something to do with the fact that the dynamic data is used (I have had no problem with other types of data in the past). Does anyone know how to fix this? I have attached the following .VI. There will be a lot of. Live on the bottom which does not load, but they are not related to this problem.

  Thank you!

  Brian

  I don't know what you're doing now, but a part of your origianl code is simply ridiculous. Your DAQ assistant takes a single point. You convert that into an array. If you had converted into a scalar value (which is) first place, your graphics update would have been fine.

  If you want to remove the DAQ Assistant, and then select generate DAQmx code. You'll be a little more closely, but it seems that it generates a NChan DAQmx Read 1Samp instead of a 1Chan 1Samp DAQmx read.

• Dynamic data of several channels in table, then save in Excel

  Hello

  I am acquiring data from several channels (4-5) and I'd like to collect samples at low rates (10 Hz for 3 minutes max). For various reasons I use Dynamic Data type, although I know that it is not the best way (some say it is a wrong data type ). I also want to save data to a file (the best option would be data excel file).

  If I acquire data 10 times per second, it is quite slow to save in excel (this is the slowest option of all types of data). So I would like to fill a table or matrix of acquired data and then write Excel file (I use scripture to measure file). But I don't know how to do - if I convert DDT in DBL, build an array and connect it to change registry, it works but I lose the information in column names and I'm wasting time. If I connect to build the table a DDT and then shift record another, it returns the table 1 d of DDT. I would like to have 2D DDT, which collects all the information loop.  Is there a suggestion how to solve?

  I'm sure it would be easier solved my problem with the double data type but I also use select signals VI which is the VI I am not able to replace at this time.

  Good day

  Lefebvre

  I don't know if there is a question here, or what.  Doing what you say you want to make, acquire the data of 4-5 channels at low rates (10 Hz for 3 minutes) and save the data in an Excel file (I assume you mean really Excel, i.e. a file with the extension .xls or .xlsx) is really a very easy thing to do in LabVIEW, especially if you are not using :

  • DAQ Assistant
  • Dynamic Data
  • Write to the action file.

  Indeed, you seem to realize this, but I guess you want to 'do the hard', in any case.

  Good luck.

• Indexing of dynamic data

  I'm trying to store all the information through dynamic data, the main loop cable, by indexing. I want just to capture all the data that flows through these wires and put them in Excel at the same time. My only thought on indexing was to create a separate loop outside the main loop just if I could the values of the indices. I tried to put indexing in the main loop, but then I capture only one second of data. If I put another while loop in my main loop to index, my program enters an infinite loop (maybe because my stopping conditions were not correct).

  I enclose my entire program to this message. The problematic loop is highlighted in yellow.

  If anyone has any suggestions or advice, please answer! Thank you!

  I did some work on your VI and I had a few thoughts:

  1. you must get rid of the DAQ assistant - done

  2. you must organize your code better.

  3. you should look into a state machine - look at the example file NOR to see how it could be done.

  4. Add an event structure to manage the stop function. This should help with the problem you are experiencing.

  5. you should always try and adapt your code in a window.

  6. you will need to check that all the calculations and graphs work after I changed things around.

  I hope this helps.

• Read a data point every time via the sound card

  Hello!

  I'm reading the output of an amplifier to lock that cannot be connected to my PC. So I decided to read througn my mic.

  To do this, I connect channel 1 or 2 for my microphone.

  However whenever I do a reading I can not simply take a while but only several points at once.

  10 is the minimum number of points I can get when I put the sampling of 100 and length frequency 0.1 in the VI of its acquisition.

  Any combination that translates into less than 10 points gives me an error (for example 100 sampling rate and duration 0.01).

  I thought that by indexing dynamic data to acquire its VI would solve the problem, but playback is differnet from that I get when reading lock-in amplifier

  through GPIB.

  (I'm testing with a locking amplifier which I can via GPIB interface.  So at the same time, I read with my sound card and the GPIB and compare graphs)

  Any way to read a point every time?  Or I'm getting something other wrong here?

  Thanks for your time!

  Looks like the CDA min frequency response of 10 Hz, pg 69 card technical:

  http://www.hardwaresecrets.com/datasheets/ALC888_1-0.PDF

  However, you can apply a known value of low voltage DC at the entrance to see if it reads properly micro. Note that microphones out low level signals, looks like the ADC full scale entry is ~1-1.5V so make sure that your entry does not exceed. You can use dividers of resistive voltage if necessary to reduce the input voltage.

• Dynamic data format

  I created a dynamic site (PHP/MySQL) that works perfectly except for the formatting. When my dynamic data displayed in the column of the table, I created, he is shown as a continuous paragraph, even if it is in several paragraphs in the mySQL database. I need to try to get DW to view and show the results of the research with paragraph breaks, as I see it in my database.
  
  I tried to go to the Application window > server behaviors > dynamic text window and none of the options Format gives the desired result.
  
  Someone at - it ideas? Y at - it a specific format should I choose (which is not listed)?
  
  Thank you for your time!

  CONVERT - new lines to BRS licences has been added in Dreamweaver CS3.

  If you use an earlier version of DW, pass the value to the nl2br()
  function:

  echo nl2br ($row_recordsetName ['fieldName']);

• Plot of vs - time - value

  Hi all

  I have a problem with the graphic calculator function on the latest version of the numbers.

  My goal to get a value vs. time curve to show a (potential) relationship between a fluctuation in the value in the time of the day.

  The problem is that numbers that are drawn on a time line, as opposed to a based (modular) format on the clock.

  I would like to clarify, that data to be controlled independently of the date (for example July 7 against July 11) but rather the date time (kind of 09:00 July 11 is represented before 13:00 July 7, for example).

  Is there an easy way to achieve this?

  Thanks in advance.

  Mean something like this?

  

  = TODAY () + TIMEVALUE (A2)

  Numbers of always stores a date-time value even if you have formatted the cell to display only the time or date only.  If you "plugged in" all parts of the same date (via today, for example) and add the timevalue part, you will get a set of times at the same date.

  Then trace those instead of your original date column.  Here, I've selected columns B and C and chose a "2D scatterplot" chart.
