• How to use Labview for measuring the reflectance at different wavelengths automatically

  Hello!

  I'm using labview to communicate with MS257 (a monochromator). If I do not use Labview, I have to use the hand controller (set a wavelength from 300 to 1100 under a grating (a total of four grids).) It takes a lot of time. So I want to use labview to realize the automation. But I don't know how to do, I still can put only a wavelength as a command for MS257, not making any difference.

  Does anyone know how to deal with this?

  Thank you for your time.

  So where are you stuck? It is a fairly common task. Inside of a loop, you can increment the "xxx" and build a table of responses. Look at the Format function in the chain and a knot of shift register/feedback.

• How about using labview vi of the filter and multiply vi to replace the analog filter and amplifier

  Hi all

  I use a data acquisition system to acquire a weak signal, it seems to a voltage amplifier and low-pass filter before the acquisition of data. I was wondering, if I use low-pass of the labview vi of the filter and multiply vi to process the signal picked up by DAQ, can I get the same effect as the analog low-pass filter and amp?

  Thank you!

  No!

  1. any system of sampled data must be band including prior to sampling in order to avoid aliasing.  It is impossible to remove aliasing after collection.

  2. the resolution of the DAQ system will be so low that you'll very 'fat' scanning and you will lose a large part of the information in your signal.

  Sorry, but you need to amplify and filter in the material before the data acquisition device for best results.

• How to use Labview "" buttons"" in the operation of the program?

  I try to use the ok button to run the program adds to the value of the cluster X Y (millemetre) [which is the operation of machine vision] with value X Y offset [which i will to enter myself] but... I don't ' know how it does do, now I try to use the structure of the event, but it does not work

  Please give me some advice please... by the way I've got to do this thing made by 3 days because of my calendar... thank you

  This software is also to locate the orientation for robot to cling to the object using the CCD camera

  Place the structure of the event within a while loop. Take a look at some of the examples provided with LV, for sure, they show it.

  Then, use the change event of value for the ok button (square button of the terminal that fram for the locking behavior set correctly).

  You can pass the data of XY to the loop to output in the same framework of the event to read the moment you press the ok button.

  How to use JavaScript to limit the number of boxes to check the user can select a PDF form?

  Here's the working solution

  Please rename all the boxes like chkBox0, chkBox1... .chkBox30 (must start with 0)

  Value of exports of each checkbox must be "Yes" (default value is Yes)

  Place this Code at the level of the Javascript Document

  -Code JavaScript document-

  var counter = 0;                Checked the meter

  -Count boxes checked again when the document is closed and reopened.

  for (var i = 0; i)<= 30;="">

  If (getField("chkBox"_+_i).value == 'Yes') {}

  Counter += 1;

  }

  }

  -The function of validation-

  function validateCheckBox(name,value) {}

  If (value == 'Yes' & meter)<>

  Counter += 1;

  } else if (value == 'Off') {}

  counter = 1;

  } else {}

  getField ("name") .value = "Off";

  App.Alert ("you can select only four checkboxes");

  }

  }

  -End of Document Javascript-

  Now put this line in the MouseUp event all checkboxes

  Box - Code MouseUp event.

  validateCheckBox (event.target.name, event.target.value);

• How to use LabView created notifiers in Teststand?

  Hello

  I have created a big enough sequencer with LabView engine and I start by creating a bunch of reporters, clusters, and queues.

  You can see in the first screenshot. See to see how I did it:

  http://forums.NI.com/T5/LabVIEW/unmatching-notifier-vs-type-declaration/m-p/3058887

  Then I tried to re - use these components with Teststand in a separate thread in order to control the background running the thread using notifications and messages.

  But where created Refnum LabView, Teststand await strings or object references.

  See the other 5 screenshots.

  No idea how the two match without having to rewrite all to help continue of Teststand?

• This module requires a Lynxmotion AL5A robotic using LabVIEW arm control

  Hello world

  I'm a little confused about what NI LabVIEW toolkits to be used in order for me to program the arm Lynxmotion robotic. Somebody has arms lynxmotion robot programming experience using labview? What should be awared by selecting the correct tool boxes. Do I need to have the tools of design and simulation of control? What about embedded design modules? Please help me.

  Thank you

  Hi DK,.

  The Module digital output NI9474 high-speed Sourcing should be more than enough.

  In fact, we have a demo of work available by using the AL5D and NI CompactRIO. The concept should always be the same property.

• How to use a chart control to enter data?

  I have a GUI that contains a chart control.  By making no use of events graphic I was able to add and remove a data point on my chart by clicking the chart control and then handle the event in the vi... no problem.  What I would really like to do now is to allow the user to choose a data point on the graph and drag it to a new location, providing an easy way for the user to define a given waveform... I'm stuck!

  I'm using LabVIEW 2009.

  Have you considered using the sliders to tide you over?

  The sliders can be moved so logically (in your code) combining the cursor to a data point, you can use the cursor to move the point.

  The cursor bonus feature is if you show that the legend of cursor the user can enter the values.

• How to use a structure of the event in a Subvi

  I am using a structure of the event within a Subvi.  The Subvi has a table constructor that built tables and the structure of the event is used so that when the program runs, it allows you to change the elements of the array.  It works, but when I apply within a Subvi, it does not work properly.  This goes into a Subvi, because it will be part of a much larger progrram, so it must be modular.

  If you are using a structure of the event, it is not a Subvi.  If you worry about modularity, you should not use the structure of the event.

  You seem to have a fundamental misunderstanding of modularity.  An event structure must be placed in a while loop.  If you have a while loop in a Subvi, you have transferred control of your program to the Subvi.  You are not at this stage modular.  Your higher level GUI has no control.  You would have to create a stupid system of variables to pass data down to the loop to stop the loop and return to your main VI.  This is not a good design decision.

  Instead of searching for a way to make something broken, you should spend effort trying to understand what you really want to accomplish.  You should also spend some time to learn how to work the event structures.

  This application is small at the moment and it is already on the way to the unreadable.  It's a terrible thing to do for you.  Break these habits now.  variables are only when absolutely necessary.  Using subVIs to accomplish individual tasks, do not run the entire application.  With the structures of the event, use a value of stop button change event for will not be held hostage to the time-out.  If your variable is '2' in it, you're doing something wrong.  It has to be something different between set points, put it in the name.  If you want to make the subVIs, create an icon.

  But first and foremost, invest time in understanding dataflow

• How to use a secondary control and tab?

  I am the first time using the secondary tab control. I've seen some examples of shipping.

  The purpose of the VI:

  1 termpol1 on: should be on when the mouse is down (for VI without TITLE 4)

  2 termpol1 Off: the mouse is down

  Another screen should come to show:

  3 Process2 on: should be on when the mouse is down (for VI without TITLE 5)

  Off 4Process2: should be on when the mouse is down

  If I click on process On1 a screen should come up from the VI and process 2 then another screen should happen.

  How can I do? How can I create reference to the main VI VI IE 3 Untitled.

  You open the vi FP before insertion of the vi It is by mistake because you will not be able to use overtime to a vi Panel already open so you can remove and move the mention vi Panel of sup and the run method of the vi then you must check the status of the vi to operate inside the void Panel.
