• cDAQ-9181 with NI 9402: after the first cycle of meter reading lack certain counts in all subsequent cycles.

  Hello

  I'm reading pulses TTL of a generator of service using a meter. I apply a 1 kHz signal to the meter. Each time counter reads the pulses correctly in the first cycle of measure, but it lacks some counts in all subsequent cycles.

  I use NEITHER 9181 cDAQ chassis and NI 9402 module with 2014 LabVIEW and NI Max 14.0.

  My computer has the Windows 8.1 operating system.

  Please find the VI joint and the front image after EXECUTION.

  I also used the same VI with chassis USB cDAQ-9171 . Results have been improved, but the same problem persists.

  What could be the reason for this, please guide.

  Thank you!

  1. the loop time is defined by software and therefore won't be compatible.

  2. you restart the meter patch between each iteration of loop - so that the task is restarted, it does not take samples.  The new start is faster on the USB device from the device ethernet due to the latency of the lower bus, so that explains why the behavior is improved on the 9171 compared to the 9181.

  Using method 2 meter would be a clever way (maybe too smart...) to implement which, according to me, you are looking:

  

  This will configure a second counter (ctr0 is paired with ctr1, ctr2 is paried with ctr3) to generate a signal of a period known (time measurement).  The meter is taken into account the number of external pulses during this period, and since we are because data in terms of 'Ticks', it will give you the number that occurred during the measurement time.  This measure is repeated for the specified number of Cycles without software-timing or latency between cycles.

  The appeal of reading will have a time-out value long enough to ensure that all cycles have completed (or you can query to see if the task is made first of all to give the user the option to cancel the measure).

• Increase the frequency of sampling on the cdaq 9174 with neither 9212

  Hi all!

  I am trying to increase my sampling rate on my nor 9212, that I use with a cdaq 9174 and LV 2015. Apparently, the sampling frequency depends on the time of conversion and can be changed between the high speed, the Best 60 Hz rejection, best 50 Hz rejection, and high resolution. (see http://www.ni.com/pdf/manuals/374358a_02.pdf, page 6). My maximum sampling frequency is 1.8 Hz, which indicates the use of the mode of synchronization of high resolution

  I found this documentation explaining how to change with a crio:

  http://zone.NI.com/reference/en-XX/help/373197D-01/criodevicehelp/cRIO-9212_rt/

  However, I can't change it when the module is not in my project with my cdaq. My question is: How can I change the conversion without a crio time?

  Thank you very much!

• Why can't acquire data from strain and resistance at the same time with a NI 9219 module?

  Hello

  I use a chassis with a NI9219 module 9172 cDAQ to try to acquire the strain and resistance at the same time, with the Labview SignalExpress software.  Is this possible?  When I try to display two values of signal at the same time, I get an error of assistant DAQ 50103 'the specified resource is reserved.  The operation could not be performed as indicated.  I used to be able to acquire the strain and tension at the same time, but now even that gives me error 50103.  I have hours trying to figure this out.  Any help would be greatly appreciated.

  Thank you

  That's all!  Thank you very much, now I can sleep tonight - seriously!

• I have CC installed on PC can I use creative cloud on the iPad Pro with a smooth transition between the two?

  Hey - I hope you can help. I'm under CC on a PC and I buy an iPad pro. Can I perfectly send/receive the vectors/graph between the two devices - in other words is going to talk about Apple and Microsoft to another. So if I'm with a client and then come home can I download/send what I did on my ipad and continue to work on my PC?

  Sorry to sound stupid, but I can't seem to find real answers anywhere.

  Thank you!

  Hi Vicki,

  You can use Adobe Creative Cloud on your desktop (PC Win) and also on your device (iPad pro).

  Just be sure that PC supports the desktop versions of the apps (desktop applications Adobe Creative Cloud|) Adobe Creative Cloud ) and the iPad device will support mobile applications (Mobile Apps ).

  You can synchronize the work on one of the applications to the course in the library of creative cloud in order to adapt them to another application.

  Hope that helps!

• Who uses a 2600K on the mobo Z68 with Quicksync, Virtu, Dmode/Imode?

  Now they announce with coding accelerating on the mobo chipset Z68 by new technologies such as Quicksunc, Virtu Imode or Dmode (Asus brand)

  combining the power of the internal graphics chip 2600K and your Nvidia video card.

  Does anyone have experience? Or forget us about it?

  Sorry that I have not been on the Forum lately. I've been very busy, I couldn't really keep an eye on the forums. The Virtu does not support applications based CUDA last I checked and does not work with Adobe. You must manually switch the main screen to switch between the video card Nvidia and Intel to switch to Quicksync. You must also run atleast first without the active Intel screen while using the engine of the MPE, or the system will BSOD. The Quicksync has some decent export options but the quality reports are not the best. I would avoid Quicksync currently, up to what Intel has been able to pass the stage SDK/tests on this.

• Run an application of LabVIEW 8.6 in win 7 (using the cDAQ-9172, 9219, 9422)

  Hello.

  I did a LabVIEW application for a few years. At that time, I used windows XP and labview 8.6. The material used is the cDAQ-9172, with NEITHER-9219 (reading of four strain gage sensors) and a NOR-9422 (using only a single input frequency).

  First of all, can I install my old version of labview 8.6 in my 64-bit computer to windows 7? I got an error message when I tried...

  Second, how much should I install? My old computer was slower after you install labview with its pilots. Perhaps I installed too much? Do I have to install 1, 5 GB DAQmx drivers?

  If I need a new version of labview for win 7, how much is an update?

  Thank you!

  Hello

  First version of LabVIEW which is supported on Windows 7 is LabVIEW 2009 SP1.

  Regarding the drivers, if you want to develop or run VI:s in LabVIEW with the DAQmx API, then you must install the full DAQmx driver.

  If you only meet built executable in the LabVIEW environment to run, then you just DAQmx Base Runtime.

  If you also want to be able to configure the data acquisition equipment (to the MAX) in a runtime environment, you should also Configuration DAQmx execution.

• DAQmx 201105 error using the cDAQ 9403 module

  I'm using the DAQmx C library of Borland Delphi programming.  My hardware configuration is a cDAQ-9174/9178 with a 9222, 9401 and 9403 module.  Here's where I manage problems at the moment:

  I want to run three different tasks on my 9403 module:

  Task1 is an output buffered with frame sample clock/cDAQ1/do/SampleClockTimebase to 100 kHz (channel 0-5)

  Task2 is a software-timed output (20-25 channels)

  Task3 is a timed software entry (channels 26-31)

  Task2 and Task3 me give 201105 errors when I try to use DAQmxWriteDigitalLines and DAQmxReadDigitalLines, respectively.  Create channels for these tasks works very well, however.  Apparently, there is some reason to believe that the 9403 won't perform Task1, except that it works without raising errors.  This work by accident and only because I am using channels 0-5?  That's why I'm getting errors when trying to use the tasks 2 and 3?

  Any thoughts are appreciated.

  Hi André,.

  This is expected behavior and is documented in the digital i/o considerations for devices of the series C using DAQmx.

  The 9403 is registered has a series module that has the following restrictions:

  • You may not use modules series and parallel together on the same task timed material.
  • You may not use modules series for the trigger.
  • You can do static and timed tasks at the same time on a single serial module.
  • You cannot material timing in one direction at a time on a module in the two-way series.

  You can do task 1, or you can do tasks 2 and 3.  You can not do the tasks 1, 2 and 3 together, as you saw.  You can do it with an additional 9403 if you move the software tasks timed to the other module.

  The 9401 is a parallel module that does not have these restrictions.  Snacking is configurable, however, which means that you must set the direction in groups of 4, but it seems that you are using too many lines for a single 9401.

• Frequency control of NOR-9476 on the cDAQ-9188

  I am using a cDAQ-9188 with a NI 9476 module, and I would like to control the frequency of the digital signals that the module was released. I tried to use the example of Pulse Train digital continuous with control of the frequency, but impossible to select the 9476 since there is no internal counter, and when I change the 'Digital output' task, the frequency control disappears. Is it possible to use the internal counter of frame to control the output frequency of the 9476? I need to get out a range of 0 to 1 kHz.

  Most of my program would output a digital signal of a certain frequency every second in real time from a given table. For example, if I have an array of [10, 20, 15, 100,...], it generates a model of up/down of 10 cycles per second for a second, followed by 20 cycles (with a shorter period) for a second, then 15 cycles per second for a second, and 100 cycles per second for a second.

  I tried to use avoiding to do, but it was very slow, with a delay of 63 ms between each cycle, when I wanted a 1 ms delay.

  CDAQ-9188 has 4 counters built in, but you cannot access it by using the NI 9476-, but the NI 9401 module can access the built-in meters.

  The good news is that you can always generate your pulse train, using counters, it generate on the PFI lines on the chassis itself and not through your module.  If you need to generate more than a pulse train, or use all four counters, you will need the module NOR-9401/9402.

  In order to get the speed, you will need to use the capabilities of hardware counters timing.

  I hope this helps!

• How to speed up loop DAQ triggered using NOR cDAQ-9174 with NOR-9215 and NOR-9402

  Hello

  I use LV2010 and NOR-DAQmx 9.2.2. I have a NOR cDAQ-9174 with a NEITHER-9215 4 channel 100 k simultaneous ADC and NOR-9402 4 channel DIO module trigger and reset.

  We run WinXP sp3 on a Dell M4400 core 2 duo @2. 26 Ghz.

  I used the code example NI DAQmx for acquisition of tension with trigger HW. My goal is to try all 4 channels on the 9215 simultaneously when a trigger is received on channel 0 of the 9402, after data is read, I use channel 1 on the 9402 to reset the trigger of the target material.  I have a version of this work, however the maximum event rate is ~ 16/second. I have the Setup 9215 for finite samples / 10 samples per channel which is ~ 400uSec of conversion time and I realize he is above in the appeal of vi, but ~ 50mSeconds worth?

  The target detector can put out up to 1 k / event triggers / seconds.  Only, I received a rate of 8 per second and I added the NOR-DAQmx control vi driver and chose "commit" this did double the rate.

  My question is what is the maximum rate of loop for these devices (trigger/conversion/reading device / reset) and start over? I noticed that just let free the 9215, carried out using the 'Acq & chart internal strain Clk' raised only the rate of events up to 20 Hz.

  Thank you

  normbo663

  Hi normbo663,

  You can get this works far better assuming you have an available counter (there are 4 on the backplane of the 9174).

  DAQ Compact supports the tasks of meter output "redeclenchables" that can be used to generate a finite pulse train.  You can set a task of finished meter redeclenchables output to be used as sample for your task of analog clock.  The task of the meter output will be re-Army (less than 12, 5-25 ns) as soon as it's finished out the last pulse.  The task of analog input would be configured to run continuously, but it would only sample based on the output of the meter triggered.  For an example, see here.

  You can reference the internal counters on the cDAQ without signals through a routing module using: cDAQ1/_ctr0 (right click on the chain counter control, then select i/o name of filtering and check channels internal to add these options to the drop down).

  Thus, with the tips above, you should be able to immediately re - arming your analog acquisition on the 9215 using one background basket counters.  It seems that the second half of the application is to use a second channel on the 9402 to reset the trigger of your DUT.  You can deterministically generate this signal so by configuring a 2nd redeclenchables meter out task (single pulse, but this time).  All you need to do is the initial delay on the appropriate value for your analog acquisition.  Trigger this counter on the same PFI line that trigger you your analog task from.

  Using counters to generate the signals you need in a deterministic way, the loop becomes is no longer a problem (as long as your input buffer does not overflow).  You may need to re-read several triggers at the same time for the loop to keep (for example to read 1000 samples each, which would correspond to 100 triggers 10 samples).

• Using instrumented hammer model PCB 086D 50 with the NI9234 module and chassis OR cDAQ 9188

  Hi all

  I need to try to shock with a PCB 086D 50 instrumented hammer hammer. I use the chassis OR cDAQ-9188 with the NI9205 and NI9234 modules. The hammer is connected to the NI9234 and accelerometers are connected to NI9205.

  When I test the modules in SignalExpress I get very good results for the dog, but the accelerometers are ok. Also, if I am controlled the hammer OR Max where I have the option to activate the IEPE the result is ok. In SignalExpress, I couldn't find the option to activate IEPE.

  I have no experience using software, but I started to learn. Does that mean that I need to program the system for my setup in LabVIEW? Also, the installer of the equipment makes sense, the modules that I plugged on the cDAQ can be used simultaneously? Should I have the additional device in order to use the hammer with cDAQ 9188?

  Thank you very much

  Emina

  You can enable IEPE in SignalExpress. Here is a configuration for a single power hammer and three accelerometers a 9234-related.

  

  You don't mention the model for accelerometers. They are also the IEPE sensors? If so, have what conditioning of signals you added before the 9205?

  The Assistant Sound and Vibration (built on SignalExpress) contains an example of Impact Test. The Sound and Vibration Toolkit comes with a sample project for the impact test. With free evaluation period, go ahead and look at how one of these examples is implementing the configuration and the triggered acquisition.

• amplification of the strain by using the cDAQ

  Hello

  I am a newbie in the use of DAQ hardware and hope someone can help out me.

  I recently bought a cDAQ with the NI 9237 to measure the strains. The strains that I try to measure are very small 1 series micro. A bit of research showed me that I need to amplify the signal to measure these small strains (correct me if I'm wrong). But I'm not able to find amplifiers for the cDAQ.So, the questions I have are-

  1. is it possible to measure these small strains (1 strain micro) using the cDAQ? If so, do I need an amplifier?

  2. If I need an amplifier, are there more specific for the cDAQ with the 9237? If this is not the case, how and where can I get one?

  Thank you

  SID

  SID,

  These results were very shocking for me also, so I looked into it further.  It seems that the 9237 can do better.   Assuming you're within 5 degrees of the calibration temperature (25 ° C), 9237. 05% of span of error and. 05% offset error.  With the range of configuration and 25mV/V full-bridge, you can calculate the absolute accuracy of the 9237 with the following formula.  (Sound of full-bridge = 0.9 microV/V)

  absolute accuracy = (gain error * reading) + (error offset * range) + (noise)

  Do the math, we get

  25mV/V + / 25.9 microV/V

  In a full-bridge configuration: V/Vex =-(Gauge Factor) * strain

  
  

  With a typical GF of ~ 2.0, we can say that the accuracy of the strain will be

  12.5 mm/m + / microm 12.95/m

  It's a little more in the range that you hoped for.  Sorry for the confusion.

  If this does not work for you, we sell solutions PXI who will be able to measure more precisely.  Similar math help and type of configuration of full-bridge with SMU 4330 plug, we get:

  12.5 mm/m + / 3.48 microm/m

  In my view, that it is card data acquisition based on a bridge more precise and accurate that we sell.  It requires a controller/chasis PXI.

  Please let me know if you have any other questions!

  Sincerely,
