• Outbreak of DAQmx N-sample and the Acquisition using DAQ Assistant

  Hello!

  I'm still fairly new to LabVIEW and I am working on all the points of connection. I would like to acquire a finite number of samples of analog data from a CompactDAQ system when a Boolean event of internal software (like a button of VI). I followed the examples to implement the acquisition with the DAQ Assistant, which works very well. I don't understand how I can use a software trigger, but I don't see how hardware triggers are configured in the trigger tab in the DAQ Assistant.

  I don't know that this should be very simple; Maybe I'm just ignorant of the configuration used for this sort of thing. Also, I could find soon I need to go beyond the DAQ Assistant for some of what I want to do, so any pointers to good references or tutorials on programming DAQmx are welcome.

  Thank you!

  Ryan

  You can simply put the acquisition within a value of the Boolean control change event.

• Call Assistant DAQ of Labview code

  Hello

  How can I call the DAQ Assistant dialog box

  

  from Labview code, as well as a program compiled with Labview runtime?

  Now, I can set the Express Assistant DAQ vi in the block diagram, but cannot be changed during execution.

  But the configuration of data acquisition is not static. The end user must change.

  A similar dialogue is used inside the Measurement & Automation Explorer with a task global DAQmx.

  Can I call this dialog of Labview?

  There is a way to call the DAQ Assistant of MAX of Labview code to create or modify a task DAQmx: Screw Wizard DAQmx LabVIEW

• Analog input voltage assistant DAQ

  Does anyone know why theres error when you use two assistant DAQ (in a while loop at the same time) for reading of the analog input voltage?

  There is not a problem if you use a wizard to data acquisition for analog input voltage reading simple.

  If you get an error, wouldn't it useful that you have told us what it was, we may be able to explain it?

  I'm guessing that you have error-50103, and if you look in the forums for '50103' (leave out the negative sign), it will give you the answer for this question has only requested thousands of times before.

• Impossible to get assistant daq to appear

  Hi all

  I am currently using student Labview 2009 edition, I also installed NOR-DAQmx 8.8, I don't have that a little project to do with the acquisition of a voltage using a DAQ6008.

  I'm trying this project: http://www.me.umn.edu/courses/me2011/labview/LabVIEW-thermistor.pdf the problem is that Assistant DAQ is nowhere to be seen in my Labview program.

  Is there something that I missed?

  I searched the palette DAQ and its certainly not there.

  Any help is appreciated!

  Hello Marko,

  The problem is that NEITHER-DAQmx 8.8 is not supported by LabVIEW 2009. You must download and install DAQmx 8.9.5 or later for LabVIEW 2009 supports. I recommend the latest version of NOR-DAQmx:

  NOR-DAQmx 9.0.2 - Windows 2000/7 x 64/7/Vista x 64/Vista/XP

  Let me know if you encounter other problems.

• Gap between the screws with the NI 9237 & Assistants DAQ

  I have a set of scales attached to a NI 9237 module in a cDAQ 9174. I have two separate screws following the gross load cell output (mV/V). The two screws acquire through a DAQ Assistant. Two Assistants DAQ are configured in the same way, and yet they have different output values. Reads around 0.003 mV/V being not charged while the other reads 0.03 mV/V - an order of magnitude difference. Any thoughts on why this is? Thank you!

  Thanks David,.

  Finally, I followed him there down to a calibration offset null being applied to a DAQ Assistant and not the other. Is there a way to remove this discrepancy in the DAQ Assistant? It is not evident. I only noticed after DAQmx code conversion and managed to remove it it.

• Assistant DAQ missing even after installation of 14.0 DAQmx f1

  Hello

  I am currently using NI LabVIEW student 2015 Edition. I have an NI USB-6009 data acquisition card, and it came with a marked installation CD OR-DAQmx 14.0 f1. Then after you install the software from the CD, I was looking for the DAQ Assistant, but he is still missing. No action in terms of getting DAQ Assistant on my VI?

  Best regards,

  Benjamin

  Install the latest DAQmx driver for compatibility with LabVIEW 2015.

• Assistant DAQ need graphics update during the collection of samples of N

  Hi all, I have a question about the DAQ Assistant. I need to acquire data at low rates (ca 10 Hz). I want to acquire Let's say 100 samples. I join my card day ten times per second. But when I choose N (100) to 10 Hz, updates to the table only once - 10 seconds samples. Is there another way to take samples of N and be able to watch the chart updated 10 times per second the use of samples keep (10 Hz, 1 sample to read) with timer that ends the while loop after 10 seconds?

  When I use the last mentioned way and write data in the file, I always acquire 101 samples, not 100. And I think that's not an ellegant way to write data to file 10 times per second (higher sampling rates, LabView is unable to write all of the samples file .xlsx, with the CT (s) files, it's better).

  Perhaps to collect 1 sample on request would be ok, but so far I have not had an experience with that.

  Thanks for your replies

  First of all, read this excellent whitepaper on the DAQ-mx hardware and stop using the DAQ Assistant, who does not have the flexibility you need to do what you describe.

  Don't you see what you want to do?  You ask to taste 10 Hz and want to update for each samplegraph.  So how many samples do you take before you add the data sampled at the table?

  Now, with the knowledge of what you have learned in the white paper, put some (you can do it in one) features DAQmx to start the Acquisition, in a loop For (with this that connected to N?), take the appropriate number of samples and send that to the table, and then out of the loop, stop the Acquisition.  If you use tasks (created by MAX or using the command 'New task' of the LabVIEW project), you should be able to do this with as little as 3 functions DAQmx (I'd probably use 4) and a single loop.

• Properties assistant DAQ does not open

  We use version 8.0.1 LV with daqmx version 8.7.1. Win Xp with a PCI-6025E, SCB-100 card is attached. I can measure the thermistor in the SCB-100 in the measurement and automation for the hardware seems to work OK. The problem is to use Daqmx in LV I am following the tutorial at http://zone.ni.com/devzone/cda/tut/p/id/2744 . When I drop the Daq Assistant on the block on that diagram it does not open the property page for me to configure an analog input, double-click don't work, simple click and selecting Properties does nothing. In the measurement and automation, I can create a task and he launch the daq - mx box and setup of measurement with the PCI-6025E. Probably a setting issue somewhere, any ideas?

  See this discussion and this one.

  Hope this helps

• There is no inputs or outputs Assistant DAQ

  During the last day, I lost access to the inputs and outputs on the DAQ Assistant. I followed the instructions posted here with no luck.

  Some information:

  I'm a cDAQ9172 with a series of modules to HAVE/AO/DIO/Relay operating. I also use a SCXI1000 with a NI1303 multiplexer thermocouple.

  When I access channels of AI on MAX, I can read out very well. When I place a DAQ Assistant on a white VI, I can configure the channels very well (T/C type, range, etc.). When I build the Express VI, nothing happens and it returns the attached figure.

  According to the instructions from the link above, I installed and reinstalled LabVIEW and MAX and updated with the latest version updates. I am now in a bind, because it does still not properly, as he had done in the past. I'm frustrated. Thank you!

  
  

• How can I check the voltage values on the acquisition of data with a data acquisition assistant and the custom scale?

  I use a custom scale and the DAQ assistant to acquire data from a USB DAQ device.  How can I display voltage gross values at the same time?

  Thank you

  David

  Do not use the ladder custom, but read the raw data using the daq assistant and adapts the data later. Or the scale of the data using the inverse of the custom scale.

• Assistant DAQ synchronization settings

  I have what I think, it's a simple question. I'm under DAQmx with the following parameters:

  Acquisition mode - meter samples

  Samples to read - 1 k

  Rate (Hz) - 10 k

  First of all, I understand that under continuous samples never stops read data and control the box 'samples to read' reading how it is averaged together to create a single data point. If this is incorrect, please specify my question may be null.

  My question is; with my settings, is she out 10 k datapoints per second (collected from 10 000 000 readings per second)? Or is it take 10 000 readings on average 1,000 of them at a time, then exit 10 datapoints per second?

  It will display every 100 m 1000 samples each sample will be taken to intervalles.1 to ms. There is no average goes everywhere. Arithmetic is basic - samples divided by samples/s is equal to acquire both. If you had 1000 samples per second and asked 100 samples, the acquisition time would be the same, but each sample would be 1 ms apart.

• Starting assistant DAQ prior to the main version of the program

  Hello

  I would need to begin to acquire data via the module Wizard DAQ 100ms before my main program in the while loop starts (see attached photo). How could I just realize this (without having to include the DAQ assistant in the while loop itself)?

  Thanks for your help,

  Thibault.

  Put a picture of flat sequence between the beginning of mx DAQ and the while loop.  Connect the wires of error through it.  Put a wait 100 ms function in the frame.

• Why generate code OR DAQmx to assist DAQ?

  If I set up a channel of AI using the DAQ Assistant why converting using NOR-DAQmx code generate the menu? It runs faster? What is the advantage of the conversion?

  Dave

  In addition, you have more control over DAQmx code vs express screws if you need configure the parameters that were not in the express VI, as export a trigger causes another trigger, you might add the code to do.

  Finally, the express VI contains probably more functions you really need.  A lot of unnecessary code.  With DAQmx, you put only what you use.  No unnecessary functions wasting time.

• Assistant DAQ - HELP! why I don't Assistant DAQ on my 8.6.1 range of entrance of the student edition?

  Help. When I create a new Vi (for the 1st time) have installed LabVIEW my palette entry does not contain the DAQ Assistant? Is this true or an installation problem (no erros installation were marked upward)?

  How am I supposed to gain entry without the DAQ Assistant analoque signals?

  Solution - I had installed DAQmx before LabVIEW. Apparently LabVIEW MUST be installed before DAQmx. DAQmx then reinstalled and it worked!
