I have to set the auto dispose preoperty to 'true' and wait until done
to 'false'. So if I dont have the application builder include the
front panel ( which is what I want exactly) then would the reference
be not closed by itself ?
How can I prevent it from happening ? Do I have to do it
Hi!
I have a XY Graph with 2 plots. For screen displey I have the Graph
with black background color. But for printing I set the BG-color to
white and the Plot colors to black.
Before changing the Plot colors I save the colors with a property node
(setting active plot and reading plot color).
Wow, you are cool!
At first, I am sorry if I wasn't clear enough. It was probably because
I didn't understand my problem and LabVIEW exactly.
Anyway, I think what I want looks like (3). However, I would also like
to know other possibilities, at least (1). Because I will need it
eventually to
How to convert the charge acquired using fieldpoints into their
equivalent wheel load.
You have not mentioned the hardware that you are using to generate and
measure pulse. If the hardware you are using is FP-CTR-500/502, I
have a suggestion. The terminal count value that is being used has a
direct effect on the value of the frequency generated. If the value
is set in the range

My system consists of differents vi=B4s.Some of them are used to read

The values that I read, go through differents vi to be

Is it possible to achieve elapsed time resolution of less than 1 ms in
LabVIEW 7 Express?
The OS resolution for putting threads to sleep is currently 1 ms, and
the accuracy of when the threads varies between the versions and setup.
The thread timing will be pretty good in the general case,
I agree, it sounds like your panel is consuming all the resources it is
given. All of the suggestions given so far are good ones, but you might
also find it useful to be more systematic about speeding it up and
trying them out. Clone your application so that you can instrument it
to measure
Thank you very much for your answer.
However, I am interested in knowing the time taken by some part of my
labview code down to 100 microsecond resolution, rather than delay. Is
it still impossible?
Hi,
The CRC calculation is given in the manual as FF+1-X.
Sorry for making the confussion with minus sign.
I admit I do not know much about calculating the CRC but the example
is given in the manual as FF+1-X that is why I am just using that.
And it works. I communicate with the device and I read
No. Im trying to replay the sequence to get this behavior
Yes, but I just used the properties window, and there is not left
property there
actually the hardware is unimportant, I am currently testing and using
a square wave function generator (0-5v signal) .. although I use the
built-in waveform synthesis to generate either square or sine waves
and get the same problem.. The problem seems tied to all the timing
measurement VI's ..
This is very neat.
It is exactly what I was asked to do.
I have noticed that it displays one indicator at the time.
Now I just have to understand better how it works so that I can modify
it to enlarge 1 or more indicators at the time.
Thanks a lot,

I think this is only in LV 7. I have 6.0.2. Thanks anyway.

Hi All,
I have posted an update to my utility Find All Used Unused VIs (now
at version 1.30 and compiled in LabVIEW 6.1) for your immediate
download at:
https://sourceforge.net/projects/findusedvis/
The program has the following features:
- lists every VI used by by your main VI
- can
Hello,
Is it possible for labview to find the maximum value of a function?
The function contains 2 variables, and all of them changes from -inf
to +inf. If labview can achieve them, how to do it? Thanks in advance!
It is also possible that the NI news server only allows connections
from e.g. US IPs. Are you coming from a foreign address? It will be
more efficient if you use a local server anyway.
According to your screenshot, you are also using a local news server
(narad.cc.iitk.ac.in). If this is the
Have you found the answer? I have the same problem...
Could you create a demo, e.g. a simple toplevel VI that shows the
behavior?
You are running 6.01b3, which is pretty old. Maybe it's time to
upgrade ;-).
I've seen upredictable scale placement scrambling before, so there
might be a buglet in the LabVIEW code. Have you reported it to NI?
If you need better resolution than 1ms, you need to go to a LabVIEW
Realtime system. (You should also make a distinction between
resolution and precision. I would not even trust a timing result
of several ms on e.g. Windows. Too many other things could be going
on).
If you just need to do some
Hi all,
I upload a new version of the "Bird's Eye View" utility

Hi,
I got a simple little question: I've search without succes for a
function or Express VI that justs return me the time of an execution
of my application. I'm reading data from an external device and I need
to check about frequency. So, if there's a way to get my execution
time (not just the
I need this for LabView 6.1
Ok, thank very much, but I can't upgrade, I use Labview at university.
Thank you very much anyway.
Have you been able to repeat the problem? If so, what steps lead to
it?
There's a number of things that could be going wrong here - could you
please post your VI so we can have a closer look?
Do you simply want to offset the magnatude of the waveform or allow
for time shifting of the waveform as well? One method I have used is
to offset the waveform and rotate it forward and reverse taking the
maximum value of all three waveforms for the new upper limit. similar
for lower limit. If
I will post a library when I get back to the office. We use WAGO
controllers fairly often. Give me an e-mail to send them too.
However, I am interested in knowing the time taken by some part of my
labview code down to 100 microsecond resolution, rather than delay. Is
it still impossible?
Ah. A common technique listed in the other post is to use repetition so
that a lower resolution timer can be used, then averaged
Thanks for the advice.
What do you mean by a real database? And so, how do I configure MS
Access such that it can handle multiple clients. I know this could be
done but I don't know how to.
I've had some success while testing the execution on one local
machine, with the two applications and the
Thanks for everyone's replies - I've been able to track down the
communications manual, and it seems fairly straightforward. That said, if
anyone has some old VIs lying around that they don't mind passing on, I'd
really appreciate not having to re-invent the wheel :)
Cheers,
Christopher
can u attached LV lower version, I mean 6.1 because I only have this
version.
Thank u very much for reply my question
Thank you so much. This is exactly what I wanted. You are my saviour.
:)
Northwind:
Why certainly! Just look in the Math subpallete, and you will
find zeros and extrema vi. Alternatively, you could save the
function as a waveform and use the wave max/min vi.
