Scan AI from all channels in 6023 daq board

I am trying to use single point scan for every Analog input channel in my 6023 board. I get a scan out of range error. I have tried multiple configurations. Basically it is only letting me scan 9 out of the 16 channels. I am scanning 0-5vdc signals. I have even tried the multiple channel scan with the same error.

You will get a scan out of range error if your board is set for differential instead of single ended configuration. Find this property in MAX.

  • Is it possible to access channels on a DAQ board while the device is used by another application?

    I am curious if is possible to run an application that reads one channel of a DAQ board while another application already is reading different channels on the board.

    Shoe,
    You can have more than one application accessing a DAQ board at a time but not for the same type of process, such as analog input. I tried a setup where one program was accessing analog input channel 1 and a separate program was accessing analog input channel 2. Only one program would run at a time. However, you can have an analog input program and a separate analog output program accessing the same board running at the same time.
    Hope this helps!

  • How to calculate the phase difference between two square wave (acquired from two channel in one DAQ)

    Hello everyone ,
     I need a quickly help that as below :
    I am trying use PCI-6220 to acquired six signals from one rotation encoder (channel A, channel B,channel Z ,and their non-signals) .The encoder out signals will be square wave and 4000pulses per revolution. I set it rotation at 300rpm speed. I need show every square wave of six out channels in waveform and measure the A-B phase difference to check if the value is correct (designed value should be 90deg) .
    I have no idea how to measure or calculate the phase difference of two square wave base on synchronizate to acquire these two square wave from two channel on the PCI-6620....
    Anyone can give a idea how to calculate the phase difference with two square wave ?
    Thank a lot and Thanks again...

  • How to Read from multiple channels

    Dear Sir
    I am acquiring data using FP-RTD-122 using OPC Client software. I ahve made one socket for that and i am using command
    CWDataSocket1.AccessMode = cwdsReadAutoUpdate
    CWDataSocket1.URL = "opc://localhost/National Instruments.OPCFieldPoint/FP Res\FP-RTD-122 @1\Channel 0"
    CWDataSocket1.Connect
    v = CWDataSocket1.Data.Value
    where v is a variant type.But this is 8-channel RTD so how can i read values from all channels using single socket connection Because at presnt i have to use 8 sockets for all eight channels.

    At least as of FieldPoint 4.0 and earlier (I do not know about 4.0.1 or later), the OPC Server did not support multiple channel analog items. Thus to read all eight channels of a FP-RTD-122 module, you would need 8 separate socket connections. For discrete modules (boolean), the "All" tag, is treated as a single 8 or 16 bit number.

  • Connecting more than one sensor cable to screw terminal to collect more than one signal in single DAQ board channel?

    I don't know if this topic is being posted in the correct location. I am new to LabVIEW and the hardware associated with it. I am using an NI 9237 DAQ board for a senior design project in engineering and I was informed that I can make multiple connections to a single screw terminal which in turn will connect to one channel of the DAQ board. To give the specifics, I have two pressure transducers and would like to connect them to the same screw terminal and channel on the DAQ board yet separate them when acquiring data in the VI. Does anyone know how to do this? I know is is essentially knowing what pins do what on the screw terminal but I can't find this anywhere. I am currently doing the job with two screw terminals and two of everything else (RJ50 adapters, etc.). I would appreciate any input. Also, please let me know if I am posting in the wrong board and if possible, which board I should be posting to.
    Thank You,

    bsteinma,
    What you may have heard is that you can measure multiple signals on the same task, not on the same channel.  By tying both of these signals to the same channel, both signals will compete to drive the line.  The channel on the card will only interpret this garbled signal and you will get no useful data.  If you are new to wiring up hardware, I recommend configuring a task within Measurement and Automation Explorer and then clicking on the tab along the bottom of the page titled, Connection Diagram.  This will show you what electrical connections to make.  Then, in LabVIEW you can read multiple signals (channels) and manipulate each signal how you would like.  
    As far as boards go, you will generally find an answer where ever you post, but the Multifunction DAQ board is a great place to post when you have questions regarding hardware (like your 9237).

  • Scanning from all-in-one printer to Elements

    I have a Dell 4000 desktop computer, running Windows 7, 32-bit version, an Epson Stylus SX515W all in one printer/scanner etc, and Photoshop Elements 6.  I am told that I cannot scan from my Epson scanner to Elements 6, and that I will need Photoshop Elements 10 to do this.
    1. Is this correct?
    2. If so, do I have to buy a full version of Elements 10, or can I buy an upgrade?
    3. If only an upgrade is needed, what is it called, what will it cost and where can I download it from?
    4. If I have to buy the full version of Elements 10, will I need any other software to get it to scan images from my Epson Stylus SX515W?
    5. Where do I have to look to find your reply?
    Best wishes

    Hi Nick,
    First of all I would like to inform that PSE 6 is not tested on Win 7 and is very old version.
    In order to scan  from PSE, you will need Twain plugin which is required to scan from within Adobe Applications.
    To check if you already have twain or not, follow this :
    Navigate to C:\Program Files\Adobe\Photoshop Elements 6.0\Plug-Ins\Import-Export\
    If you find a file called "Twain", then you should be able to scan, if not then you have to download Twain from here : http://www.adobe.com/support/downloads/thankyou.jsp?ftpID=4688&fileID=4376
    Save the file, unzip it and then follow these steps :
    Close PSE 6.
    After that , navigate to PSCS5OptionalPlugins_Win_en_US\PSCS5OptionalPlugins_Win_en_US\Optional Plug-Ins\Win32, here you will find Twain_32.8BA file
    Copy this file and then paste under  : C:\Program Files\Adobe\Photoshop Elements 6.0\Plug-Ins\Import-Export\
    Launch PSE 6 and check if you get the option to scan under File >> Import menu
    If the above solution doesnt work, then you may have to ugrade to PSE 10.
    The price for upgrade is $79.99 and full price is $99.99
    You can purchase full and upgrade both from Adobe.com website
    Thanks,
    Baljeet

    I have a wirless network. I connect all my computers to it and a printer. I can print wirelessly from all computers. I tried to add the printer to my new Macbook, which is connecte to the network, but can't find the printer on the add printer and scan icon on preferences. I downloaded a installation printer utility from the Manufacturer (lexmark), but it didn't work. Any sugestions?
    Thanks,

    You would need to get the IP address of your printer then manually add a network print queue.
    To get the IP address, on the control panel of your printer, press on Setup > Network Setup > TCP/IP > View/Set IP address.

  • How can I use LabVIEW to ground floating SCXI-1520 channels (in order not to lose scanning capabilities from the multiplexer)?

    Currently I am reading quarter bridge strain with several SCXI-1520s. When in MAX I noticed my values were no longer reading after a certain gage and as I attempted to troubleshoot, found out that the multiplexer in this module will not scan past any open channel (or if it does, channel results are not consistent) for a very logical reason. If I lose a gage, I usually lose any data from any subsequent gages which we really cannot afford.
    Are there any suggestions programming in LabVIEW (right now i'm using NI-DAQmx with an analog task set up)so that each time my loop executes, the program will check for any open channels and either not collect that data or change the order of acquisition (i.e. place the open channels last on the scan list?
    I'm open to anything that might be of help

    Yes, by "open channel" i mean that there is no signal returning from the gage because it has broken off the structure or the signal to the terminal block has been disconnected somehow.
    When I lose data, I'm referring to the data that is acquired on following channels. The behavior appears to be fairly random (which was a troubleshooting nightmare ) but usually if a channel is open, then that and those behind it in the scan order do not return any data. It returns a number like 10.357E-6 and I do not pick up any noise or fluctuations. As far as I understand, the multiplexer stops scanning at this point (open channel) because it has nothing to ground to and subsequently "hangs" - not (or randomly) scanning the following channels. I have gone through the bridge configuration and as of yet, have not figured out how to fix this using any hard-wiring techniques. I emailed NI, and was sent a library file to "ground the channels" but it actually resets the Analog input Task I have defined each loop.
    I am new to NI-DAQmx so I do not know if this will alter any configurations I already have in MAX for NI-DAQmx. Will it override? I am concerned it will slow my loop time, and also I cannot see the code for this sub.vi so am a little skiddish about using it if i do not know if it can be tailored to my app.
    What do you think? Am I on the right path?

  • Acquiring data from all the analog channels of NI-3202 NODE using a single sensor

    Hi all,
    I would like to know that can i be able to get the data from all the four analog channels of NI-WSN node 3202(analog input node) connecting only single sensor on the analog input and connecting all the remaining analog inputs using wires and also shorting the ground pins corresponding to each analog input pin.
    By configuring the each channels like 0.5 sec delay for every analog channels to acquire data. can we get the sensor data from all the channels by doing this. basically here i am trying to increase the minimum sampling rate of the ni-wsn NODE 3202 which is 1s.
    I this approach is correct or we cannot do this.
    Thanks

    Stefan,
    In terms of differential and RSE, channels 0-8 should default to differential when using test panels.  Differential needs two input channels to function correctly and these channels must be spread apart by 8 channels. (i.e channels 0 and 7 are a differential pair)  Channel 13, on the other hand, will default to rse if chosen as the reading channel because there does not exist another channel that is eight away.  I am not quiet sure if the virtual channels will default channel 5 into being differential but I will check into it.  If it is differential as default then you may run into problems since channel 13 is utilized in both strain gauge reads.   
    "The second question is, if we can also use the "voltage" setting for measuring strain gauges? we did that in the past, using LabView 6.2."
    If you are referring to "voltage" as acquiring a signal with custom voltage with exciation then I would reccomend using example in LabVIEW called Acq Wheatstone Bridge Samples (with Calibration).  This can be found by navigating to LabVIEW's example finder and expanding Hardware Input and Output>>DAQmx>>Analog Measurements>>Strain.
    I have also included some useful links that may provide more insight into the SCC modules as well.  Also, what is the excitation voltage and power that your strain gauges are expecting?

  • Why can I not use the channel name, which is obtained from the function of DAQmx Task, as the input of the channel name for the function of Get Channel Information of DAQ?

    Why can I not use the channel name, which is obtained from the function of DAQmx Task, as the input of the channel name for the function of Get Channel Information of DAQ?

    Not a lot of details here, but my guess is this isn't working for you because you are wiring in the task to the Active Channels Property and not the actual Channel Name. I have attatched a screenshot of what I believe you are trying to do. The Task has 2 channels in it, so I need to index off one of the channels and wire it into the active channels input of the Channel Property node. Then I can read information about that channel

  • Recovering DAQ Board channel lists from a program in LabView 2

    I am working on updating a LabView program that was written in LabView 2 or even possibly earlier. I got the conversion CD and upgraded the program so I could open it on LabView 6.1. Unfortunately, in the process of this upgrade, all information regarding the access to the lines of the board was lost. At the time it was last used, it accessed a Multifunction I/O Board for Macintosh Nu-Bus, Part Number 320174B-01 and was using a Macintosh IIci computer. I have a new DAQ board, the NI-PCI-6221 that is in a new Dell workstation, running Windows 2000 and LabView 6.1. I was wondering if there is a way to recover the channel lists that should be in the subVis. Do I need to track down a copy of LabView 2 or 1 to do so? This conversion also involved a Macintosh to PC switch, which if I understand correctly is a problem in the earlier versions of LabView? I was hoping to find the best way to recover this information, so I can properly adjust the program and configure it to my new DAQ board. Thank you.

    Hello again, and thank you for all of your help thus far. I'm trying to obtain information on the access to the lines of a DAQ board in a program that was written on a Macintosh IIci in LabView 2 (The program and some of the created subVIs are attached). I was hoping someone may have access to LabView 2 and an old Macintosh that could run this. If the program opens I'd like to see snapshots of the screen for the DAQ subVIs. This would help me greatly in what I am trying to do. Thank you.

  • Need continuous acquisition of 16 channels through SCXI-1125 to PCMCIA DA board + FFT on all channels. Can it be done?

    Where's the limit? Assume a new Dell Latitude running NT with 128 MB RAM and a fast P3. Equip it with the DAQCard-AI-16E-4 connected to an SCXI chassis with 2 SCXI-1125 modules.
    How fast can I run the sample rate (per channel) if I want to do continuous DAQ on all 16 channels while computing the power spectrum of all channels once per second (using one second's worth of samples)?
    The DAQCard has a tiny FIFO, and I'm hoping to use pretriggered scans so I don't have to wait for data. Is that an option without the DMA functionality of the PCI E-Series boards? Without it I will have to constantly empty the FIFO into a "software" b
    uffer which will cost boku (many) processor cycles, correct?
    So what say the experts... how fast can this thing run? How about if I ditch the laptop and go PXI with the whole deal? Lets make the case!
    Thank you!

    I believe the PCMCIA interface is going to be the limiting factor in this case. The maximum continuous rate for a DAQCard will vary from computer to computer, but it isn't extremely fast.
    Being optimistic, let's estimate 64 K samples/second. I don't know if this is high or low nowadays, but it is higher than I could ever achieve a couple of years ago. Divide that by your 16 channels, and you have 4K blocks. I think you could process this in 1 second easily. This gives you 1 Hz resolution up to 2 Khz.
    Now, if you ditch the laptop and go to PXI, it is a whole different story. DAQ rates will not be the limiting factor. You just need to find out how large of a block you can process and keep up.
    My approach to this problem would be to figure out what analysi
    s you need, then figure out what hardware can accomplish it. Do you really need 1 Hz resolution? Do you need to process every bit of data that comes in? Are you going to store the results, or just display them on the screen? Can you do post-processing of the data if necessary?
