• How can I set the time axis on my waveform table to show run time that is to say whenever I start the program I should have 0 as the starting point

  How can I set the time axis on my waveform table to show run time that is to say whenever I start the program I should have 0 as the starting point. I've been messing around with the without success. I'm under Labview 2012.

  Thank you!

• Put the data of the set point in a waveform graph

  Hello

  In a graph of measure, which is the result of a waveform, I would add data of the set point as well. How can I add this data to set for the chart value?

  In a control loop system, the output is controlled by a labview program. I would like to see the point of this system as well as in the graph, these thresholds are changed at random times, so I don't know how to create a waveform of these data. Should I create a waveform of the setpoint, or y at - it another option to show the set value in the chart?

  See you soon,.

  That can make it much more difficult.

  At one point an array of 1000 points need to be assembled (obviously). How do depends greatly on your structure. Synchronize the time of the two signals can be very difficult. It would be easy if the set value only changed once a cycle of 1000 point.

  You may want to read the SP as an analog input, so you get 2 samples of the material here. In this way the two will always be synchronized. But I'm done alleady assumption, like this, the signal is an analog input (and the target value of one analogue output). What equipment do you use?

  I think always need you a loop to get data and a loop to set the SP. The two loops will be more parallel execution GLSL and synchroniseent. The trick is to synchronize, or for the deterministic timestamps in two loops. If you can make that happen, you 80% there. You could do loops timed loops (using the same clock). Then you get the timestamps in two loops. The MS loop has the queue changes, pushing the value and time. Then the loop of data can use values and hours to create examples of sp 1000.

• move the data points on the waveform display

  Hello

  No idea why the waveform display to my VI has shift the data points? The third tab of the screen does not display this problem. I took a video of what happens to better illustrate what I'm talking about and attached my VI to identify the problem.

  I am currently a sample of data from a DAQmx and storing in a queue until data backup button. Everything works well, but the problem is the display of actual data, which, although sense points, it shows move in a small area around where they are drawn in the first place. It happens even when I erase the visible data and restart the collection of data, as shown in the video.

  Thanks for any help you may be able to provide.

  The amount of data you draw? If you draw a lot more datapoints that there are pixels on the x-axis of the graph, you can get peaks that appear to move because of graphic interpolation LabVIEW has to do.

• Re-sample a signal for the least points of data using the value average

  Hello

  I'm trying to resample a large wave to a smaller wave form. I want to use the average value of all data points in a time interval of the initial wave as the new value of the new waveform. For example I have want to resample a waveform of 100 points from k to a waveform with 1 k points, in the waveform again the value of each data point is the average of 100 data points in the old waveform. Is a convenient way to do this in labview? The VI of waveforms resample seems only provide coerce/linear/spline/FIR interpolation modes. Thank you very much for your help.

  Just use build a waveform is your decimated table, dt is climbed by the decimation factor and t0 can remain the same.

• How to obtain the build version of the exe when running

  Hi all!

  Is there a way to get the build number of the EXE file in the runtime?

  There are version field in the exe, property that can be autoincremented construction each construction process.

  It will be very useful to show in a particular area on the application window.

  But I can see now that in the operatin system file property.

  I couldn't find this point between the nodes of the Application property.

  Perhaps this information available in rintime by another way?

• Export waveforms to the worksheet File.vi

  Hi all

  I try to use the waveform to export as a spreadsheet on a waveform that is added for the duration of a while loop with a registry to offset. The VI works fine and acquires all the appropriate data and the corresponding points however when I hit the stop button to exit the while loop is not fast or pop up asking me to save the excel file. The VI ends just after leaving the while loop.

  Nothing else has this problem? I think that I am likely missing a step somewhere, but I based the block diagram of a video presentation to youtube (https://www.youtube.com/watch?v=GBhJk5Tnshc) and I can't seem to find my mistake.

  Please find attached my diagram and the VI and apologies for the link text above, I'm not sure on the exact validation protocol here.

  Any help would be appreciated!

  Hi ofis.

  you alluded to run your VI on a target of myRIO!

  RIO platform usually has NO attached screen to display a UI to the user. When there is no interface user you cannot display a file on/in the user interface dialog box.

  Just provide a constant filepath to the VI WriteWaveform - and don't forget to choose a path is available on the target of myRIO: you can not record directly on the hard disk of your PC!

  On your VI:

  Why are you warking with a waveform at all? I don't see any setting of rates specimen, so a waveform of construction seems foolish to me! Simply collect your data in a table and use the simple SaveSpreadsheetFile function to save this table on disk (myRIO)!

• problem while conspiring waveform of the signal in real-time

  Dear Sir

  I use LabVIEW8.2 and USB1208FS for data acquisition. I have configured hardware with LabVIEW and data in real time using the Universal Library VI AInScBg.vi. When I draw my signal on the waveform (amplitude vs. frequency) then on axis x frequency ranges from 0 ~ 0.49 hz. I have change the sampling rate of 1000 Hz to 4000 Hz, but on the x-axis without frequency change occurs and it is set at 0.49 hz. Can you please guide me how can I get the frequency of my own interest on the x-axis.

  I enclose you daughter of LabVIEW for reference.

  Kind regards

  Simply change the text label of the x-axis of frequency does not automatically the correct calculation. You do not pass in the sample information in the service spectrum, so you get no frequency information. You can see the strain on the entry point. The function expects a data type of waveform as input. Without it, the dt will default to 1. Then, use the function create a waveform and add information from dt to it as well as your table of Y.

• Mobile data does not and the name of the Access Point settings are not available

  I don't have a mobile data, not even the small up and down arrows or letters beside the sims signal bars appear.

  I tried all the troubleshooting settings and different type of network, the airplane mode is off, mobile data are no limit, no power save modes are on. Phone is dual sim so I tried on the two sims and tried to disable the other sim and changing the sim slots, both sims are loaded with a credit of data that works in other android devices. WiFi works fine. Factory reset does not help.

  There is that one thing that I can't not try troubleshooting. When I select settings > more > mobile networks > access point names, it says

  "Access Point name settings are not available for this user.

  Maybe if I could put APN I could get mobile data. How can I do or how I can try to get mobile data to work?

  Phone's Xperia M4 Aqua E2363 with build 26.1.B.2.102 thanks if you can help

  This text is a bit misleading, which is something that I have forwarded internally as your comments.

  If you have no NPP stored the phone displays the text "the name of the Access Point settings are not available for this user" even if you use the owner account and have access to the settings.

  Try to download the automatic settings from settings-> more-> Internet settings and see if that helps.

  Hi Francis,.

  Thanks for posting the query on the Microsoft Community Forum.

  From the description, it seems that the error revceive you associated with VSS snapshot.

  1. What security software is installed on the computer?
  2. Do you have any third-party backup program installed on the computer?

  To begin troubleshooting, I would suggest that you do Check Disk

  • Press Windows key + R
  • Type "cmd" to open the command prompt.
  • Type Chkdsk/r , and press enter.

  Note:

  If all available hard disk data can be lost when running chkdsk, as the chkdsk attempts to repair the affected area.

  Reply with more information about the issue so that we can help you further.

  I had the same problem with a HP dv5000 has an Intel Dual Core processor, after installed the 10 Pro Update window cleaning, after the update sent by Windows Update Service left me with this problem.

  Thank you post I did check in the menu properties C: Tools.

  After that, I was able to create a Restore Point.

  Thank you very much for your message.

• Way to package the shortcut pointing to the network drive

  I have a package with 2 files - a .ini and a shortcut on the desktop. The .ini file will fine SystemRoot. The shortcut on the office lights, and points to a network drive, but fails it as in package.ini, the source for the shortcut, which is the entry point main, pointing to a target that is not in the package, which is a file on a network share, which is mapped to the user through a login script.

  I tried build the package with the shortcut pointing to the .ini file, as it exists in the package and then try to generate scripts to change the path of the shortcut target, timing of the launch of the shortcut, but I can't get that to not work. Any ideas?

  I've already fallen on this kind of installation so I know a workaround for it but I'll be honest with you; What is the point of creating a virtual set for a shortcut and an .ini file? One of the main objective of virtualization app is isolation.  As a best practice and avoid possible isolation question (s), your package must contain all the files, that is to say, all of these files on the network (drive P :) must be placed in the thinapp package.)

  But if you still go with this configuration for any reason, you can try the following:

  In the project folder:

  -Create a shortcut in the folder % desktop (create it if it does not exist) and type the following location: P:\SBRTS\SBRTS. EXE (you will need to have your mapped P: drive)

  -Name of your shortcut "SBRTS.lnk" (or any name you want)

  -Change your point of entry as follows:

  [Clinic Workstation.exe]

  Source=%desktop%\SBRTS.lnk

  ReadOnlyData = Package.ro.tvr

  WorkingDirectory = P:\SBRTS

  Shortcuts = % Office

  (Note that the WorkingDirectory may need to be adjusted. Normally the folder holding the binary is the working directory)

  -Rebuild you app with build.bat

• May not know how to fix the bug of the decimal point in this calculator code

  Hi guys, I am new in flash and is currently learning how to build a simple calculator with multiplier (more, less, multiple, divide, change of sign and decimal point), but I'm stuck on the decimal point and change the sign.

  var multiplier_old:Number = 10;
  var multiplier_new:Number = 1;
  
  // .: Sets the multipliers so that new input numbers become decimals of a lower unit column
  action_point.addEventListener(MouseEvent.MOUSE_DOWN, function():void {
    
            multiplier_old = 1;
            multiplier_new = 0.1;
            point = true;
    
  });
  
  // Takes intput from the input_ buttons and adds it to the input after applying the multipliers.
  // If `point` is true then the multiplier_new is divided by 10, also as described.
  function inputNumber(n:Number):void {
    
            input = input * multiplier_old + n * multiplier_new;
    
                      if (point) {
                                      multiplier_new *= 0.1;
                     trace(multiplier_new);
                      }
    
            output_txt.text = input.toString();
  }
  

  Decimal point

  The problem is that when I entered 2.7 in the calculator, it displays the values in output_txt correctly. But then when I entered 2.78, it will display 2.780000000000000000000000002. This will happen also to other numbers if the entry is too large.

  What I want is just 2.78. How can I change the encodings make 2.780000000000000000000000002 2.78?

  Sign of change

  Any tips on how to start on this one?
  

  Thanks for your time,

  Kamel

  You must use rounded in order to keep the numbers down to limited decimal values.  To display specific decimal values using the String class toFixed() method when you write the text in the TextField.

  To change the sign, multiply by-1.
