  2. Hi All,

    Need your help.. what I'm trying is I have one slider gain, As I change the value of slider then I want to change the value of say Y parameter from 0 to 1 and after some time say 2 sec I want change the value of Y parameter back to 0 but with the decrement of 0.2( 1-0.8-0.6-0.4-0.2-0)like that... Any idea how should I go about it

    Thanks in advance!!!!

  3. Hi Karthik,

    You can use the filesize output of the "OpenFile" vi . Use that filesize ouput as Count input of the "FileRead" vi. basically the vi will read untill it reaches to the final count. Hope this explains

  4. Data Changed is in the OpenG comparison pallette. You do use OpenG, don't you?

    Hey Thanks Guys. :worship:

    Todd,

    I was a OpenG user but few days ago due to some problems I have formated my PC so I lost all my data. Now I have downloaded the OpenG again.

    Thanks for the Help

  5. Hi All,

    I am creating a VI which will output 1 when the previous value of a numeric input is different from the current value. I am comparing those two values using the 1 sec delay. But I am having problem only for the First iteration when the Initial value of the input is not equal to 0. because the bydefault the delay block sends 0 value for the first iteration. I tried lot of things but couldn't find way arround it can somebody help me in this.

    Thanks in advance

  6. Hi All,

    I have two 1D arrays and I want to plot them on the same waveform chart but I can see only one I/P to the waveform chart. I tried stack plot property but no luck. Any idea how I can do that.

    Thanks in advance

  7. Hi Ravi:

    Perhaps application control menu>Invoke Method>Open FP will do what you want.

    It isn't really possible to "call" a sub-vi without executing the code, but this will open a vi's front panel from another vi, without actually calling the vi whose panel you open.

    Hope this helps. 

    Best Regards, Louis

    Hey Thanks Louis it works

  8. Hi All,

    I have a VI which opens up a front panel of another VI depending upon the selection. but the problem I'm facing is as soon I execute the VI it starts executing the selected VI and I don't want that to be happen so i'm wondering is there is any way so that I can stop execution of that VI unless I press the run button.

    Thanks,

    Ravi

  9. Hi All,

    Currently I'm working with Labview SIT(Simulation Interface Tool Kit). I want to plot two Different variables on the same XY- plotter. Do I need to change any settings for that, I tried using the "Stack plotter" Property But on the SIT panel I can see only One connection How do I connect two variables to the same Plot????? Any idea

    Thanks

  10. The easiest thing to do is to get labpython.  This allows you to put a window with a python script to execute right into your vi (it is a beefed-up formula node).  Or you can explicitly push/pop variables to/from python and then run scripts individually from within labview.

    Labpython will be useful for running external python scripts, but it is quite limiting because you cannot call labview from python itself.  If you desire more robust labview scripting, check out LuaVIEW.  Lua is a mean lean functional programming language, and with LuaVIEW you can call Lua scripts as well as call LabVIEW routines from said Lua script.  I originally wanted a way to do python scripting from LabVIEW, but after seeing how limiting labpython is, I'm switching to LuaVIEW now.  I've only done very simple things with it so far, but it's quite robust.  I've also come to like the Lua programming language very much, and it makes use of First Class Functions such that functions are treated just like variables and other objects, which allows for some pretty powerful techniques.
