  • Using the DAQ-9178 and 9205 Voltage Module, how do I build a 16 Channel Voltmeter with a range of 0--50Vdc?

    I have already built an 8 channel 10:1 voltage divider using 1% resistors.  My problem is there is a lot of AC noise on the DC signal and the voltages don't match my Fluke DVM which is sitting beside.

    8 Channel Voltage Screen.JPG ‏172 KB

    A little more info... Only Channels one and two have signal going to them.  Ch1, (a0), is connected to a 9volt battery, and ch2, (a1), is connected to a variable bench supply set for 17Vdc.
    The DVM is rock steady, however the LabVIEW indicators show what I assume is a product of the AC noise.
    Any help would be appreciated
    Thanks so much

  • Airport extreme will only get or send e-mail messages, or allow Safari to function for about 5 minutes.  After that it doesn't respond even though the green light is on and diagnostics says there is nothing wrong. Have to unplug again to get a response.

    For the past 2 days Airport Extreme works for about 5 minutes and then will not receive or send e-mail messages, or let Safari work.  The only way I can send or receive is to unplug Airport Extreme for a few seconds, reconnect and then work frantically for 5 minutes before it does the same thing.  The green light stays on and the diagnostics tells me nothing is wrong even though no mail is moving.
    Any ideas?

  • How to load a custom waveform for use with DAQ voltage generation

    I would appreciate some advice on how to take a custom waveform (just a modified triangle wave with pauses at the tops and bottoms) and use that to control the voltage output from a DAQ. 
    Some background:  My intent is to use the waveform to control mirror scanning for a LADAR imaging application .  Because our DAQ (NI-6251) only has one clock, it cannot update the X and Y channel voltages independently. I'm using a triangle wave to control both axes, which works fine for the X direction.  However, to prevent the Y axis from incrementally steping up after every X pixel, I'd like to construct a waveform, similar to a step pyramid, so that the Y axis remains constant over the X sweep and only updates to the next row after all X pixels are collected.
    I assume I can make the desired plot in excel, and then read it in somehow - but this is where I start to get fuzzy.  Can any one point me to an example or tutorial on this?
    Some other questions:
    1. Do I needto worry about scaling? will my custom plot need to contain a specific number of points (perhaps the exact number of pixels in the image)?
    2. If I change the image dimensions, will I need to revise the control waveform in the Y axis?
    Thanks in advance,
    jimmy

    This thread didn't appear to go anywhere.  I am trying to do something similar and was looking for help.  I want to create a repeating output voltage wave based off the excel file attached(with times).  Is there a way to have my program match the output voltage and time with the table attached on a repeat and send that signal to the output?
    Thanks,

  • Standalone application for data acquisition using NI DAQ card

    I have made a standalone application in labview GUI for data acquisition and signal processing. if i have to run this application in any other computer what all softwares should be installed other than labview runtime engine...NI DEVICE DRIVER CD alone is to be installed or do i have to install any other software for data acquisition using NI daq card??
      thanks and regards
    Solved!

    You should only need the run time engine, The device drivers for the device, maybe need VISA drivers if you are doing serial or something of that nature, You may need the channels or tasks created in NI measurements and automation if you created them there.
    There may be other things that you will need depending on what you include in your code and what tool kits that you have installed.

  • 6602: How to use 8 counters simultaneously in C++ using traditional Daq for frequency measurement

    Hi Everybody;
    I'm new to Ni-DAQ cards and working on NI PCI-6602 Card in Borland C++, I should use Traditional DAQ for my project. Now I want to use all the 8 counters simultaneously for frequency measurement.
    1.Where should I connect my External signal, to source or gate, at present I have connected to source.
    2. How to set parameters and start the counters simultaneously, what are the parameters to be set for frequency measurement.
    3.How to start counting.(parameter settings)
    4.Should I set any PFI Lines or by default are they set to counters.
    status = GPCTR_Set_Application (1, gpctrNum, ND_SIMPLE_EVENT_CNT)
    status = GPCTR_Change_Parameter (1, gpctrNum, paramID, paramValue)
    iStatus = GPCTR_Watch(1, gpctrNum, ND_ARMED, entityValue);
    status = GPCTR_Watch (deviceNumber, gpctrNum,ND_COUNT, entityValue)
    what is the paramID in my case, Clear and appropriate answers would be very helpful and thanks in advance.

      I have made a program with LabVIEW 5.1 based on NI 6602, in which four counters were used.
      Counter 3 is used to generate pulses, which are directed to the gates of counter 0, 1 and 2. 
      The source terminals of counter 0,1 and 2 receive pulses, individually, to count how many pulses appear during the time interval of each gate pulse.
      The results are stored in a data file.
      In order to test its performance, only one signal of ramdom pulses is sent to counter 0,1 and 2.
      But I find that at the beginning the counts for the three counters are the same, but the following counts are totally different!
      What's wrong? And how to solve such a problem? Does it have something related with synchronization?
      Thank you very much!

  • Can I use my DAQ on two different computers?

    Hi there.
    Sorry if this might seem like a stupid question but I'm trying to save money lol. I have two test stations, each station has it's own computer and power supply. The power supply powers a certain device and the computer communicates with it via an USB to RS422 serial converter. I am using the 2 analog outputs on my NI-USB 6008/6009 DAQ to control the 2 power supplies. AO 0 to control the power supply on station #1 and A0 1 to control the power supply on station #2.  I can control these 2 power supplies just fine with one computer connected to my DAQ. But i need each computer to be running tests independently. I only have 1 DAQ but 2 computers, is there way to use this DAQ on both computers???
    thanks for any help!
    Don't think twice.
    Solved!

    No.  Because there is no way you can take one USB-DAQ and plug it into two computers at the same time.
    You would probably be better off having one PC that communicates with the USB-DAQ and have your application on one computer talk to the other computer to pass commands and get back data from the USB-DAQ, probably by way of TCP/IP.
    I would actually make an application that only handled the USB-DAQ operation.  Then have the program that runs on each computer be the same and talk to the USB-DAQ application which would act like a TCP/IP server.  The program that is on one PC would call the IP address of the other PC.  The program that is on the same PC as your USB-DAQ server would just call the local host to establish communication.

  • How do I use two DAQ cards in one Labview code? Current I'm getting error " error 200558 occurred at DAQmx Create Channel.vi. One task cann't contain multiple independent devices". Can someone help me?

    The two DAQ cards are NI PCI-6070E & NI PCI-6052E. The Labview I'm using is labview 7 Express and the Window system is Window XP. I'm using NI SCXI-1000 chasis and SCXI-1102 & 1102B two modules plus a feedthrough SCXI-1180. 1102 is connected through SCXI-1349 cable to DAQ card 6052E while 1102B is connected through SCXI-1349 cable to DAQ card 6070E. SCXI-1180 is connected to 6070E through SCXI-1349 adaptor on the back of 1102B.

    Sarah, thank you for replying my question. It seems that I'm making progress everyday (smile). I'm able to run the test using both daq cards in my code now. But as I'm moving forward, I'm getting new questions too. How do I use one STOP button to control both tasks and how can I save data into one single file?
    I attached my code here hoping you can get the specifics on my application by looking at the code. Thanks very much!
    Thanks.

  • How do I find the ports a pre existing program used in DAQ?

    Hi all, 
    I am setting up a laser displacement sensor and trying to utilize a pre existing program that was created by graduate students before me. There are 4 wires coming from the laser displacement sensor that need to be connected to the DAQ but we have no information telling us where these wires are supposed to attach to the DAQ in order to run the pre existing program correctly. 
    Is there any way that we could figure this out? 
    Thank you for your help,
    mccutchen12c

    James, 
    Thank you for your help! Yes, we have looked at a couple different methods on how to tell if the information had been programmed by the previous grad students and we haven't had any success in finding that information. So I believe you are right in assuming its not documented.. We will do a better job of documenting for future grad students after us. 
    I have attached our code. Any insight you could give would be greatly appreciated!
    We have an Acuity AR200-6 laser displacement sensor with green, yellow, black and a wire that isn't wrapped that all lead to the serial port in the back of the computer and ground. We then have white, blue, orange and brown wires that do not have a location.. We did some research and the are as follows:
    white: laser disable
    blue: buttons disable
    orange: voltage output
    brown: voltage RTN
    We are starting to wonder if we are just not supposed to use the DAQ.. Can you confirm the connection is solely through a serial port? 
    Cheers,

  • How to control a digital output signal using the DAQ assistant?

    I am using a USB 6251 DAQ board and would like to control a switch. I am gathering airflow, pressure, and acoustic data on the same board (analog input) and would like the switch to trigger when the airflow value is within a pre-determined range. Finally, I would like to reverse the polarity of the switch (to off) about a second after the initial digital signal, all of which is during continuous data acquisition.
    I am able to actuate the switch only when pressing the "run" button in the DAQ assistant window. I am proficient with data acquisition but have never tried programming an output... Please help!
    Thanks!
    -a troubled researcher
    P.S. I am running LabVIEW 8.5 as well.

    blsmith4,
    You probably won't get the control of the digital port on your card by only using the DAQ Assistant. One of the following examples should provide you the functionality that you would like out of the box:
    Digital - SW - Timed Output (Simple)
    Digital - Continuous Output (More Complex)
    Continuous Write Digital Port - External Clock - Non Regeneration (Most Complex)
    Let me know if these work better for you.

  • Using NI-DAQ with Borland C++ 5.01

    Hi,
    I've got a problem using Ni-DAQ with Borland C++ 5.01 (i know this section is for visual C++ but I couldm't find any for ANSI C++). If I write a simple program with one of the libraries included in nidaq.h and if i specify the correct lib and include locations I have a problem with the linkink process; in particular it says that the function can be resolved...
    If anyone can help me I would appreciate it. Thanx
    Optoclasfo

    Hey optoclasfo,
    I haven't used Borland much, but with Visual C++ the problem normally
    happens because the lib and include paths are not added to the
    project. For Visual C++ they are stored at
    Tools->Options->Directories. If the library files (*.lib) are not
    added to the project you can get this error as well.
    I hope this helps out.

  • How to save data acquired from NI-DAQ in text format instead of TDMS using the DAQ-mx ANSI C code?

    Hi,
    I wanted to save data acquired from NI-DAQ (for example, NI 9234) in a file using the DAQ-mx ANSI C Code. The response I got was as follows:-
    One way to do it is with TDMS logging. DAQmx comes with functions designed to log to a TDMS file. This is a special file type that is used for collecting data in a logical format. It can be displayed in a TDMS viewer where data is separated into groups and channels. NI-DAQmx provides examples for how to log to TDMS. Look at the TDMS examples in the C:\Users\Public\Documents\National Instruments\NI-DAQ\Examples\DAQmx ANSI C\Analog In\Measure Voltage directory.
    However, now I want to know is there a way that using that same C code, can we save the data in a .txt file format (Text File) instead of a TDMS file? We actually want to access that file through MATLAB (that's why we want to save it in text format).
    Also on an other note, is there a way we can access & open TDMS files by MATLAB?
    Thanks,
    Sauvik Das Gupta

    There's a way you can access TDMS files in MATLAB:

    The basic reason is that we design our libraries for many environments, but Builder is not one of them. You can use the dll's (they're just dll's), but you will need to make your own library or use run-time linking.
    For more information about run-time linking, you can try http://msdn.microsoft.com and search for "About Dynamic-Link Libraries"

  • Using 2 DAQ's using one PC

    Hi all,
    Our project requires using 2 DAQ's (say for example ni 6008 & 9171) simultanesouly using one PC. In that case, is it possible to program in LabVIEW so that data from both the DAQ's are acquired & processed by single PCsimultaneously.
    Looking forward from you guys.
    Thanks in advance
    Prasanth

    The 6008 would seem to be a very poor choice. The USB connection has no method for synchronization. Why don't you discuss your specific requirements with your local sales engineer? You'll want your devices in a common chassis or internal to the pc and connected with a RTSI cable.

  • Is it possible to condition a load cell signal with a 1520 SCXI and then use it as the primary analog feedback for a 735X motion control board?

    My system
    PXI 1052 chassis
    PXI 8196 RT controller
    Flexmotion 7356 motion controller
    Flexmotion 7354 motion controller
    6259 M series DAQ
    1520 SCXI
    1520 SCXI
    1314 SCXI frount mounting terminal block
    DSM strain gage load cells
    Exlar SR Brushless PM motors
    Kollmorgen servo star CD series 5 drives
    My objective:
    I want to measure the force on the load cells with the 1520 SCXI (i.e. excite the load cell then amplify and condition its output) then I want to use this analog (force) signal as the primary feedback for my motion control system (7356 and 7354 motion controller connected to my drives and motors).
    The problem:
    The motion controller boards (7356 and 7354) can be configured for force feedback control via analog feedback from a load cell.  However the boards implicitly expect the load cell signal to be amplified and conditioned with and external signal conditioner rather then using an NI SCXI module.  Currently I’m am reading the SCXI signals via the 6259 M seriers DAQ and consequentially have no way to route the signal into the 735X boards for force feedback control.  I can use softmotion to control the motors but then I loose the fast PID update rates possible with the 735X boards.
    The question:
    Is it possible to condition a load cell signal with a 1520 SCXI and then use it as the primary analog feedback for a 735X motion control board?

    Hi GG,
    Thank you for your feedback.
    >create your own external circuitry to amplify the signal.>
    True a few op-amps could amplify and filter the signal externally but the performance of such an amateur built system will never match the accuracy and functionality of the 1520 SCXI.  That’s why we spent the $2500 for the professional version.
    >One thing that you could do is to use a UMI with your motion controller and then wire your signal from your SCXI to the UMI.>
    As I understand it the UMI is basically a break out connectivity interface for third party drives.  After conditioning and amplifying the analog force signal with the SCXI module the analog signal isn’t available to wire into a UMI.  To my knowledge the conditioned signal of the SCXI resides only in the PXI backplane (i.e. there is no physical access to the conditioned analog signal).  Can you explain how the UMI could be help here.
    Again thanks for your input GG.
