Thank u for your attention. I am sorry, but I have not been able to do
what you suggested. Your picture is nice, but it is impossible for me
to reproduce it because it uses Functions I have never seen (I don't
even know their names...).
Could you please be more precise?
I am a new user.
Do u mean to look at NI Example Finder? I have got LabVIEW 7.0, I have
tried the Search option, but I have not been able to find what you
suggested. It says: no examples match your searcg criteria
This doesn't work. The option you mentioned was not selected, but now
it is. Indicators are not cleared when I open the VI. Maybe because I
don't know what is when you say:
If your subVI is set to open FP when called
My main VI is set to open Front Panel when called. I don't know what
about the
thank u very much.
Unfortunately, the VI can't run because an error occurs. Joes Append

I shall try to understand your example from the block diagram, even if
it doesn't work
Dear Oleg,
your answer helped me very much.
My question is: how can I optimize the write to file operation, that
is I need something to control file destination name in order to avoid
that puictures are overwritten when I press again the enable button. I
am asking something similar to what is
I would like that graphs and indicators will be resetted when the VI
is open. Is it possible? A control to push at the end of the previous
session could be good, too.
Easy question: is it possible to copy an indicator or a control from
the main Front Panel to the main Front Panel?
This means I don't want to create a new control or indicator in the
Block Diagram; just want to control or check the same function from
different positions in the Front Panel (this
Acquire N Scans VI (it is an example VI) does't work to collect noise
( no input connected)
The question is: have you ever heard that some DAQ VI don't work if
input signal is too low? It seems quite strange.
I would like to choose the information saved on the header. Moreover,
headers are perfect if file saved are .lvm and opened with Notepad,
but they are not easy to read and interpret when written as.xls in
order to open file with Excel and try data operations.

Hi!
The easiest thing you can do is, from Front Panel, right click the
chart, enable Ignore Time Stamps. In this way, the starting point of
the X axis will be 0.00. Now, it will be easier to work with scales
and format axis.
N.B. The solution is good if you don't mind the graph to show you the
Do you mean acquire the trigger and the data together, view both on
the same graph and compare them and compare scans acquired in their
written form? How can I do that?
Are you italian? If yes, please help me in our language, or write me

In NI-447X User Manual I have found in Related documentation
paragraph the suggestion to read Traditional NI-DAQ C Reference Help
for traditional NI-DAQ version7.0 and later. Where can I find this
manual?
? Do I really have no possibility of doing what I
need and solve my problem with my PXI-4472? You can look at my other
recently posted questions to get an idea of my problem. Thank you and
hope to hear of you soon. Giulia
I have read Data Acquisition and Signal Conditioning Manual and I have
found that my goal is realizing a Reference Trigger. I have got a NI
PXI 4472 device, good for Traditional DAQ, not good for DAQmx. The
problem is that all the examples and exercise in the manual are
suitable for DAQmx
found (as you confirm)
that even this one is not a solution...
Thank you for attention, hope to hear from you soon.

Thank u for your attention. I have already tried adding a while loop.
It doesn't work. It continues doing just one data collection. I tried

Can you give me more informatio about this?

I have got a similar problem. My subVI contains controls and I want

was in the SubVI My Data Procesing. I need the original version,

Suppose I create a VI (main1.vi) that uses a SubVI1. Then, I realize
another version of the main VI, main2.vi, which differ from main1 by
the fact that it uses SubVI2. I don't want to create a new icon,
because there is a slight difference. Just want to associate a new
file and make this
