  1. Well I have the LabVIEW base version. The person who was in charge of the project at the time they ordered LabVIEW thought it would be enough.But if I really need the Pro version for the tests we need to do, they may decide to invest
  2. Sorry for not replying earlier I ran out off time yesterday. No I don't know yet how to do the analysis in LabVIEW. I know and I can see that it's possible to do most of the data analysis in it. But I think that in my situation it's not the best solution.As my system is running on a machine that is constantly modified by people wanting to study different parameters, it's easier for everybody to have the raw data on their personal computer. I know that Excel is far from being the best solution to treat large data, but at least it's on everybody's computer and it's working for the length of
  3. Thank you for all your inputs. LV Punk You were right, the Notifier was exactly what I was looking for. It's now stopping at the right time. I definitely have to look closely to your comment about passing queue refnums into the loops. That may be useful. Karl Rony TDMS sounds interesting I should look at it when I have a bit more time
  4. I'm using a floating average VI based on this VI. It's calculating the average for 3 of my 8 signals on the last "x" (generally 50) points. On my system I have a pump generating high oscillations of pressure. -For some measurements, I want all the data (without the average) on short period of time (max 30 seconds) so I can analyse all the oscillations. <-- this I can already do and it's working perfectly fine. -For some longer mesurements (45 minutes or more), I only need my average pressure and to save post processing time & server space I only want 1 value per second. I'm usi
  5. Here is what I'm trying to do: Data Acquisition vi: -Read data at high speed (500-800 Hz), calculate an average value. -Write to a file the average values at 1 Hz frequency. -Display calculated values on the user interface. First I had everything in the same while loop which was slowing down the vi. So after asking on the forum I was told to use the Producer/Consumer template. Now my vi is working perfectly fine for short measurements at high speed (writing to file at 500-800Hz). Depending on the test we want to run on our machine, I will only need one value per second. So I decided to
  6. Thanks a lot, You were right, that fixed our problem. We can now start aquiring our data.... bigl00z3
  7. I'm trying to create a simple data aquisition VI with 8 imputs. I've used the Producer/Consumer Design Pattern (Data) template. In my producer loop I'm writing the signals to a file. In the consumer loop I'm trying to display the values of the differents signals on my interface. I'm trying to access one of the element of a Variant data set from the queue. The Variant Data set has the folllowing structure: <Dynamic Data {[8] (<Waveform(DBL) {...}>, <Waveform(DBL) {...}>, <Waveform(DBL) {...}>, <Waveform(DBL) {...}>, <Waveform(DBL) {...}>, <Wavefo
  8. Thanks erverybody for all your imputs. And very sorry about the large pictures... I will definitely try with the "producer/consumer" way.. bigl00z3
  9. I'm totally new to LabView (and a bit lost...). I'm trying to create a simple data acquisition VI. I have 8 signals which I want to write to a file. I need a fairly high rate, I have to capture in between 800 and 1000Hz. I started from a basic VI that was developed for us and now I have to try to make it work for us. My problems are that I would like to display the calculated values on my interface: -In my first test (image below) I was placing the display inside the main while loop. The problem with this is that it's trying to refresh the values on the interface way to often (which is n
