• Determine what are the cards OR are installed on a computer using Labview

  Hello people,

  I hope that it is a matter appropriate for this forum.

  Is there a way to programmatically determine the cards OR are installed in a computer using Labview?  We have a limited number of test for material Exchange computers sometimes.  I would like to write a collection of Labview applications to know what hardware is installed and then perform some configuration based on the hardware settings.

  Best regards

• Basler sca640-70gc. IMAQdx

  Hello

  I have a problem.

  I used sCA 640-70gc and labview 2010, I do not want to use IMAQdx.

  So I try Labview IMAQ and some Pylon(basler software) C or C++ source

  but I just can't. I have try call back libray, ActiveX (cameracontrol), shared Liabrary

  Please help me man.

  How can I use c or c ++ source in labview without IMAQdx?

  Finally I use IMAQdx,

  Thx for man

• How to read the data from a channel named in windows using labview

  Hello

  I need to read the channel named in windows data. The pipe is created by python by another application. This application post permanent data on the pipe. But I don't know how to read data using labview. is it possible to read the data from different application? If possible, how to start?

  Thanks in advance

  Hi Rolf,.

  It's just, because of driving is not initialized completely, pipe read returns error 42, I added 2 seconds late, then its work perfect.

  Thank you very much.

• I want to control the speed and direction of a motor continuous using labview with pwm

  I want to control the speed and direction of a motor (essentially a toy motor) continuous generating a PWM signal in labview. I'm using L293d motor and exit DAQ-9472. Can I do this without the help of any microcontroller but only a simple labview code and the DAQ 9472 output

  There are many examples on how to generate a PWM on one in the buffer, or on a counter, but that does not support this card.  A 8 a cDAQ chassis also a BNC connector that can be used as a counter as well.  These examples can be found in help > example Finder in LabVIEW.

  Also be aware of your current limiting.  This card can drive a decent amount of current, but it has its limits.  You'll want to put an inline meter to see what is current and see how far you get to it.

• What equipment I need another for the purposes of the on/off switch, adapt output voltage/current using labview program

  This is my first time to use labview, I want to use the program to control the DC power for the start/stop it or set the output to program automatically.

  Now I had the (supply) instrument, got a computer with labview. I know that I have to buy a GPIB cable, making a connection between the instrument and the computer. But I do not know what to buy? Cable GPIB or GPIB controller. Confused.

  Thank you

  A GPIB cable, by itself, will do nothing. You need a GPIB controller connected to your pc. With the NI USB-GPIB-HS controller, you can connect directly to a single instrument and no need for a separate cable. If you go with an internal controller to a pc (i.e. PCIe), you need a cable to connect the controller to the instrument.

  You can also check if the power supply has other options such as Ethernet or USB remote control.

• How can I reverse the y-axis to have the lowest number at the top?

  Hello, I do a study on the water level of the river and I need to invert the values of the y-axis. It is very easy to do with Microsoft Office Exel but I don't know how to do it with the number.

  I have numbers 3.6.1

  Hi I,.

  I have some difficulty to visualize data and graph is to create. In my mind, data points are projected on the chart to indicate an increase in the level of the surface of the River (or debit) level.

  Perhaps an example of data would be clearer demand.

• Manual definition of the value axis scaling to a script for two or more axes file

  Hi all

  I've been using tiara for only a few days so I apologize if it's something really easy to do, but I just can't understand it. I am trying to manually set the value of 'End' for the axis is scaling of a parcel in a "report". I figured out how to set this value to one of the axis value by using the following commands:

  Dim oMy2DYAxis

  Set oMy2DYAxis = Report.ActiveSheet.Objects.Item ("2DAxis1"). YAxis

  oMy2DYAxis.Scaling.End =

  However, I can not understand how to do the same, but the value that I have on the right side of the plot for the second axis. I'm sure it must be possible to do this for each y axis, but how can it be done?

  And for extra credit! How would I be able to do a map in the report other than the 'ActiveSheet '? Is there something similar to ' Report.Sheet ("Page 1"). ... "that could be used as opposed to" Report.ActiveSheet. " ...'?

  Thank you!

  Hi Siliev,

  Here is an example:

  Dim oCurrSheet, iLoop
  
  Set oCurrSheet = Report.ActiveSheet.Objects ("2D-Axis1")
  
  iLoop = 1 to oCurrSheet.YAxisList.Count
  
    MsgBox "Y axis" & iLoop & + "\n" & _
  
           «Start: "& oCurrSheet.YAxisList (iLoop).» Scaling.Begin & + "\n" & _
  
           "End:"& oCurrSheet.YAxisList (iLoop). " Scaling.End
  
  next

• change the properties of the report axis (together begin and end)

  Hey everybody,

  I am a beginner with DIAdem reports and close to despair that I have yet found any solution.

  I wrote a script, which produces reports of various measures with 9 pages (3 2D-slots each, a total of 27 lots).

  Now, I want to put the beginning and the end of the x-axis of certain specific parcels.

  First question: tiara offers something similar to an Object Explorer (for easy access to the names of the objects drawn in a report)?

  I created two GlobalDims called x_time_begin and x_time_end to set these properties, but I don't know how to access these variables in the report (tried @... @ and @... @ the 'Axis settings' tab).

  These variables change for each measure, so each report has a different set.

  The presentation of the State is responsible from a set of. TDMS files and is not altered in the script.

  How can I find the name of a specific plot in the report can access?

  Is it possible to define the range of the x-axis in a variable at all?

  Best regards

  Nils

  Hi Nils,

  It is possible to set the x-axis of begging and positions in the scripts end (see text below).  When you create a report object in the script you can name it anything you want to access later. Otherwise, I think that the default name is the name of the object, of the number (for example the 2D first table is called "2DTable1")

  Dim oMy2DAxisSystem, oMyXScaling
  
  Report.NewLayout
  
  Set oMy2DAxisSystem = Report.ActiveSheet.Objects.Add (eReportObject2DAxisSystem, "My2DAxisSystem")
  
  Set oMyXScaling = oMy2DAxisSystem.XAxis.Scaling
  
  oMyXScaling.AutoScalingType = eAxisAutoScalingManual
  
  oMyXScaling.Begin = 0.01
  
  oMyXScaling.End = 100

  Hope that helps,

• Programmatically change the chart axis interval c#

  I got mine to work, but I wanted to just make sure I do it correctly.  I only ask because I had to use the cast and hard-coded item recovery.

  This is what works for me:

  Yaxis = (AxisDouble) Graph.Axes.ElementAt AxisDouble (0);
  
  Yaxis.Range = new range(-25000, 25000);

  I put also adjuster = 'None' in XAML.

  Thank you.

  Your approach is very good. Given that you declare the axis in XAML, you can also use a name instead of referring to it in the index location:

  x:Name="Yaxis" Adjuster="None" ... />

• XY graph with the time axis

  Hello

  I have attached a sample vi in format zip and subvis.zip. In this vi, I have an output waveform which I got after each run. I circled this waveform output in red to the "waveform.jpg".

  Now, what I want to do is;

  I want to change the x-axis of waveform (red circled in the "waveform.jpg" scale of real time (but only in a few seconds) as the one given in attachment (second digit).

  I tried many things, but do not allow to get.

  Please help me!

  Mech,

  In your University chart, go to 'ladders '. In your time (x axis), under scale factors, type 0.001 in the multiplier section.

  Kind regards

• 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!

  I can't understand what you mean. I have no formal training with labview. It took me a long time to write the simple program that I joined. Any guidance would be greatly appreciated!

  Its pretty normal for a beginner to take the time to write code. Right-click the map of waveform > Create > property node > historical data, you will get a property node, keep this at the beginning of the code and create a constant. You can also go to the VI properties and > run and select "clear indicators when it is called.

  I recommend you to go through the basic materials of LabVIEW which will give you an understanding on the basics of bases/components of LabVIEW.

• Drawn 2 data 2 the value axis on the chart of waveform

  is it possible to put 2 y-axis on a waveform graph?

  1 left and the other more appropriate?

  as I have 2 data sets, A and B.

  I would like that my data is plotted using the left side of the y-axis which is 0.5 to 5

  B data on the right side of the axis y from-25 to 105

  the two using the same x-axis

  I have all the data I need, but now I can only understand 1 tracing of data but not the other I need to be together in 1 graphic data of the two.

  any idea?

  Hi number,.

  did you read what I wrote?

  Right-click on the scale of it, select "double ladder". Right-click the scale newly created, select "Swap" side Right-click the properties of the plot in the legend of the plot and select 'Scale Y'-> 1 scale!

• Is it possible to scroll on the y-axis of a graph of digital waveforms?

  Hello!

  I use LV 8.5.1 and I want to draw 64 signals on a graph of digital waveforms.
