• clear history graphic waveform dynamic data 1 d are used

  I'm new to Labview and uses a waveform graph.  To clear what I need to provide a table empty.  I did it with scalars entered, but in this case, the entrance to the chart is a table 1 d of dynamic data beam. I can't understand how create a table empty appropriate table 1 d of dynamic data type to initialize the plot (the story line).

  It seems that there should be a better (easier) way to erase the plot...

  Thanks for all the ideas.

• 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

  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.

• problem about dynamic data to the conversion of table 1 d

  Hi all

  I have problem with the conversion between dynamic data and table 1 d.

  I wrote a simple VI to show the problem, as the attached picture. Convert dynamic data in table 1 d, and then return to the dynamics of data, I use 3 tables of waveform display data in 3 different places, but only 'force contact 2' the graph looks normal and the 2 other cards are strange data shows. In addition, the probe indicates that data are all just before going to the charts. What is wrong with him?

  Can someone help me?

  When you convert a table, you lose your calendar information.  You need to convert a waveform and manipulate waveform data.  Use a Structure of elements in Place with waveform components to manipulate waveform data.

  

• Medium-sized dynamic data analog input read DAQmx read

  Hi, I'm new to labview. Is there an easy way to index using the dynamics of data returned by a readout DAQmx x samples to calculate a moving average? My thought was to read the analog input for X samples pump with the data in another loop through the data, but I can't quite understand how index using the returned data set to extract the measurement value double returned for each sample.

  Any ideas on that?

  Thank you...

  If you get a type of waveform data, why did you ask on dynamic data? No, of course not would you use the conversion of dynamic data on a waveform.

  If you want only one channel, then your DAQmx Read could be changed to 1Chan NSamp. If your channel list only has one channel, you will get a table 1 d with a single element that can be indexed. To get the average of a waveform use the statistical function with the waveform. You use the average Point by Point, and not the average function that has a table for an entry.

  Make sure you always have context-sensitive help on. You can avoid many of these rookie mistakes simple.

• 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.

• 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 can I draw dynamic data that I get a hardware DAQ against each other?

  Hi all

  I am trying to acquire voltage and current data of DAQ hardware. My goal is plotted against votlagein current a continuous path. As the votlage is increased at intervals of 1 Volt, every second I want to see how the current. However, this data is dynamic and I need help find how to draw in a single chart. Any thoughts on how to draw the two different dynamic data against each other in the same graph?

  You help will be very appreciated.

  Thank you

  If I understand what you're saying, looks like you want to have the update of XY graph with each new data point (or points) acquired, but also choose to keep the previous data on the XY graph.  If that's what you're after, I build on my previous example.  For the method of use of the express VI build XY graph, you can simply double click on it and uncheck the "erase data on each call.  For the other method of construction of the dashboard cluster, you will need to add a few records to offset to maintain the previous itterations table values.  Here's the updated image:

  

• Dynamic Data in Array - time values

  Hello

  It's me again.

  I have read the lines of a lvm-file and save it in a table by using dynamic data type conversion. The first column, I have in the file is at the same time; I wish I had the time as the first column of the table too, but I couldn't find how to do this. I found this thread , but I think that I can not use this way because I read the unique lines and treat...

  The attached picture should show how I mean this. So, is it possible to get the time (from file) as a column in the table?

  Thank you

  Hello

  I'm afraid, because most of us never use screws express, you can have a hard time finding someone willing to get acquainted with them to analyze your code.

  My advice is to get rid of the express vi (not just because you'll get more responses ).

  Using the palette file I/O, and then something like string from picture to picture the range of string to convert your data into a 2D array can give just the output that you want.

• dynamic data in the formula is originally running slow and weird results

  I am collecting 11 channels of analog input voltage, then perform a series of calculations (different, editable) on each channel of the voltage to convert each temperature sensor.

  My first step in calculations (with the help of multiply, subtract and divide blocks) works very well.

  My second step of calculations (which includes a natural logarithm "ln") is performed with the formula block. However, the formula block has three red arrows where are the constants of entry, and the results of the formula block are intermittent and incorrect (if drawn, drop the lightning just drawn what looks like a value of 1 intermittently... If saved to a csv file, the results show a bunch of zeros and then a row of values, then more zeros).

  I don't know if I need to convert my dynamic data in a table before feeding in the formula, or if there is another way by applying a complex formula of dynamic data, or...? I would stick with dynamic data because it makes tracing easier, but I'm open to other suggestions.

  

  

  The answer is very simple- do not use Dynamic Data.  I have never understood why NEITHER created this (other than to show "how easy it is to collect the DAQ and screw Express Wizard" (and not to mention that you lose a lot of control over what you do).)  There have been many questions here in the Forums and a number of players with a lot more experience I have also made the same recommendation.

  I don't know where the dynamic data in your case.  If it came from the DAQ Assistant, by all means read this and get rid of this wizard!

• Delete data indexed all the Oracle SES data or indexed from a given source (Complutense University of MADRID, Discussion Board)

  Hello

  We have configured ITS Oracle 11.2.2.2 with Oracle Webcenter 11.1.1.8 and Complutense University of MADRID.

  We are able to index all data successfully.

  For some test case, I would like to remove all indexed data / indexed data from a particular source of backend and rerun the crawlers.

  Y at - it no SP is who can do the job or any table that I can serve to achieve this?

  Thank you

  Kind regards

  Hello Siddharth

  I would like to understand why you do not want to delete some items analyzed

  A full analysis will remove existing items and fill the backend with the latest

  In addition, items are visible by their security; so not need something stopping to get indexed

• 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']);
