How to use TRG pine in PXI-8176 controller

Dear All,
        I have Thermocouple data acquisition system. In which there are 2 chassis, (1) PXI 1002 with
PXI8176 controller with RT, PXI 6071E DAQ card (2) SCXI 1001 with  SCXI 1125 card  and SCXI1327 block.
PXI 6071E  connected to SCXI 1125 with SH1006868 cable and adapter SCXI1349.
I am using Labview 8.6 , DAQmx9.0
I have develop program for continuous thermocouple acquisition. Now i want to make program on trigger based data acquisition.  When trigger pulse comes system starts to acquire data ( and log in file) for userdefine time and stop acquisition. Again when trigger pulse comes   system again starts to acquire and stop at define time.
There is one TRG pin on  PXI-8176 controller, Can i use that one and how i can use it? Or i have to use separate DIO line for trigger?
Can you guide me how i can develop such system.
Thank you.

Solved!
Go to Solution.

Thanks Shreyas,
          Once again you help me to solve my problem. 
           As i have already mention you i have develop temperature measurement system with-out trigger. Here i am attaching my project. Now, how i can make it trigger based, means when trigger pulse comes acquisition start and target send data after some time for example 5minutes stop acquisition and restart acquisition again when next trigger pulse comes and so on.
Thanks

  • How to configure Intel Pro/100 ethernet in PXI-8176 controller for RedHat Linux kickstart installation?

    I have trouble configuring the Intel Pro/100 ethernet for the PXI-8176 controller during the kickstart installation. Did anyone have better luck?

    Not with Linux but...
    I had trouble setting it up for RT.
    There is an issue with the chipsets used and the firmware of the 8176 when sizing the bus.
    There was a KB article.
    NI support should be able to chase down your details for you.

  • Pxi-8176 controller to read data from an instrument controlled by another controller

    can i use pxi-8176 controller to read instrument data on the gpib bus from an instrument controlled by another pc gpib controller?

    Thanks.
    I understand what you're saying, but I'm also trying to understand why the following is not possible or is not more readily available:... Just as NI IO Trace (NI Spy) listens/eavesdrops to the GPIB real time, one would think that Labview would be able to do it also. One would think that just as NI IO Trace (NI Spy) publishes to a window/file/memory it shouldn't be impossible to publish to a string so that it can be processed real-time by some VI algorithm. If I think about NI IO Trace as a VI, I would think that it is already in a string format before it is published to the NI IO Trace window... why isn't that string available to Labview VIs block diagram?

  • How to use application class reference in the controller methods of BSP

    Hi,
    I have created a bsp application and also created an application class and assigned it to the application class. In the application class, I have created attribute TEXT type string(public and instance parameter).
    In the controller let's say main.do, I am trying to give a value to to the text by adding the following code.
    application->text = 'test'.
    I am getting syntax error saying field 'text' is unknown. It is not contained in one of the specified tables nor defined by DATA statement. 
    Please can someone let me know how to use the application class in the coding with an example. I couldn't find how exactly this has to be reference. Please help.
    Best regards
    Siva

    Hi,
    if you are having main controller and sub-controller then you may need to use below coding to use application class reference.
    *Data declaration
      DATA:  obj_cntrl        TYPE REF TO cl_bsp_controller2,
             obj_sub_cntrl   TYPE REF TO z_cl_sub_cntl,
             application TYPE REF TO z_cl_application.
    *Get the controller
      CALL METHOD obj_main_cntrl->get_controller   "obj_main_cntrl is the object of main controller
        EXPORTING
          controller_id       = 'SUB'   "Controller ID
        RECEIVING
          controller_instance = obj_cntrl  .
      obj_sub_cntrl ?= obj_cntrl  .
      application ?= obj_sub_cntrl ->application.
    or simply use below code in your controller method.
      application ?= me->application.

  • PXI 8176 Controller Display Blanks Out.

    The Monitor goes on standby (blanks out) randomly while my computer is still on. I've narrowed the problem down to the controller. I just want to know what options I have. Is there a part in the controller itself that I can replace?

    I face the same problem with PXI 8196. The whole system hangs up but power supply still ok. HD LED also not lights up.

  • How to use digital trigger with analog I/O

    How do I program analog input and/or analog output to start on a digital trigger (PFI pin) on PCI-4451/4551.
    I have tried out various configuration and succeeded in starting analog input, simultanuous input and output triggered by the the anlaog input signal. I have also succeded i triggering 4551 from the dedicated EXTTRIG pin.
    The problem is to trigger on a selectable PFI pin. I find the help for "AI Trigger Config" and "AO Trigger and Gat Config" misleading - some unsupported features seem to work while selecting PFI pin as source make the PC restart immediately.
    I have not been able to find any LabVIEW example that shows how to use PFI pin as trigger input.
    Using LabVIEW 7.1, NI-DAQ 7.3 on Windows 2000.
    Kind regards / Med venlig hilsen
    Torben

    Hello
    The PCI-4451 does not have any PFI lines. If you look at the user manual in the link beneath you will be able to confirm this by looking at the connector signal discriptions. The same is valid for the PCI-4451
    http://digital.ni.com/manuals.nsf/websearch/6A32358C53BB15F086256660007392DC?OpenDocument&node=132090_US
    The two ways of triggering that you have succeded are the analog triggering and digital triggering that you can peform with the PCI-4451.

    I want to know why some box of Iphone5s it's not come full accessories in box simple my iPhone 5s I have bought from Apple store last week it's first time for me use iPhone but so surprise me how the company make the phone have to use a pin to open the sim but didn't give a pin inside the box and I ask staff at store their said they also don't know some box have some of are don't have a pin come together so then they told me I have to find solution or I have to buy a pin by my self I can buy it by myself but I really don't understand how come apple big company but how it's happen like this?thank you.

    Where did you purchase this. The US phones do not come with the SIM removal tool anymore. They haven't for some time now. I'm not even sure it comes with any of the devices anymore. You can just straighten out a paper clip and do the same thing.

  • How to use SMB trigger input on PXI-8187 in LabView

    Hello!
    I have PXI-8187 controller instaled in PXI-1031 and two PXI-4071 digital multimeters. I want to trigger mesurement with external trigger. One way is to used AUX port on DMM, another can be TRIG input on PXI 8187 CPU unit. Is possible to use this possibility in LabView 7? How?
    Best regards!

    There are multiple reasons why this is not a supported feature for triggering under Windows and why NI does not recommend using the controller's SMB connector for this purpose. National Instruments has hardware that was designed specifically for extremely accurate clock generation, synchronization, and triggering between PXI chassis (PXI-665x) and other recommended alternatives listed below.
    Non-deterministic propagation delays
    1. The controller's SMB input is not guaranteed to have a defined propagation delay to the backplane. This means the SMB trigger on the Windows PXI controller is useless for customers that want deterministic triggering. Unlike our PXI-665x boards which have a maintained API and precise triggering properties, the PXI controller's SMB connector and routing circuitry is intended for Watchdog use under LabVIEW RT and isn't designed for this use case. A trigger propagating through the SMB circuitry and going to the backplane, or vice-versa, could have a great deal of variance in the propagation delay which makes gathering useful triggers impossible. This propagation delay is not something National Instruments specs.
    An excellent available workaround: Use the measurement hardware's trigger inputs
    2. The triggering inputs on our measurement hardware (that customers likely have in their system) can route triggering signals to the PXI backplane (usually through PFI lines) with deterministic results. This functionality is fully supported in most of our APIs and will be maintained between generations of devices.
    NOT backward or forward compatible
    3. The SMB input is NOT guaranteed to be compatible between different versions of our PXI controllers under Windows. The hardware properties along with an excellent workaround are the reason we do not support doing routing of triggers through the SMB connector on our PXI family of embedded controllers under Windows. If you are still interested in the beta software despite the shortcomings, visit www.ni.com/support and submit an e-mail request.

  • How to use PXI-8532 in LabVIEW Development Environment?

    Hi,
    I want to know how to use PXI-8532 in LabVIEW Development Environment.
    I'm using
    1. Windows7 32bit
    2. LabVIEW Pro 2012 SP1 32bit
    3. NI-Industrial Communications for DeviceNet 2.3
    4. PXIe-1062Q
    5. PXIe-8135
    6. PXI-8532 *2 (Names are "dnet0" and "dnet1".)
    * Both PXI-8532 are installed in the same chassis (PXIe-1062Q).
    I want to construct the system that "dnet0" sends data, and "dnet1" receives it. The data type I want to use is an array of bools.
    I made VI (test.vi), but it does not work.
    Could you tell me the reason why my VI doesn't work correctly.
    Thank you so much for your help and time.

  • How to use PXI Star Trigger for PXIe-5663 in PXIe-1075 chassis

    HI all,
    I have this sytem configuration:
    PXIe-8135 controller. Windows 7 64-bit, RFSA 2.7.5. NI-SYNC 3.4.1
    PXIe-1075 chassis
    PXIe-5663 (2x)
    PXIe-6672 Timing & Sync Card (slot #10)
    I want to trigger the recording of my Digitizer with an external trigger.
    The External Trigger is connected to PFI0 of the PXIe-6672 Timing card.
    Then, the PXIE-6672 card routes the trigger to the backplane of the PXIe-1072 (Destination "NISYNC_VAL_PXITRIG0")
    The PXIe-5663 are triggered with “NIRFSA_VAL_PXI_TRIG0_STR” as the source.
    The trigger fires my PXIe-5663 correctly, but the timing is not tight (> 5ns).
    I would like to use the PXI Star trigger instead, I think that I should be able to acheive much better synchronization with this.
    But NI-RFSA won't let me do this:
    When I try to call
    "niRFSA_ConfigureDigitalEdgeStartTrigger(rfsa_sess​ion, NIRFSA_VAL_PXI_STAR_STR , NIRFSA_VAL_RISING_EDGE)", I get the error:
    "Specified Route Cannot Be Satisfied, Because the Hardware Does Not Support It"
    I don't understand why the PXIe-5663E would not be able to use that Route.
    Any idea?

    Serge

    That explanation isn't quite right. Usually, even PXIe modules have a connection to PXI_Star. The PXIe standard added the PXIe_DStar trigger buses, and it also preserved the PXI_Star bus from the PXI standard.
    However, there is an additional twist in this situation. I'm assuming that your PXIe-5663 includes a PXIe-5622 as the digitizer. It turns out that a synchronization technique called NI-TClk has eliminated the need for our more recent digitizers to rely on triggering from PXI_Star. I was able to find some documentation that includes this information, here and here. Given that, I think you have two options that should result in better synchronization.
    The first option is to use TClk; I found an example program that demonstrates using TClk to acheive phase coherent signal acquisition across two 5663s. The second option is to use cables of matched length to connect two PFI front panel terminals of the timing board (6672) to the PFI1 front panel terminals of the digitizers (5622). The timing board would accept the external trigger on PFI0 and then issue triggers on PFI1 and PFI2 with around 500 ps of skew (manual, page A-4) . The digitizers would use NIRFSA_VAL_PFI1_STR as the trigger. I hope one of these solutions will meet the demands of your particular application.
    I will also follow up with the owners of the RFSA product documentation to see if we can include a note about why PXI_Star is not supported in some cases.

  • PXI-8176 usb serial port multiplexe​r driver installati​on

    How do I install the USB drivers for a USB/serial port multiplexer on a PXI-8176 with LV Real Time OS?? The PXI-8176 has two USB ports.
    Thanks
    Peter

    Buzz,
    Thanks for making your post here in the Discussion Forums.
    Your USB question is an interesting one. While you may be used to using USB hardware with your computer, USB hardware is not generally used in the LabVIEW RT operating environment. As this pair of short KnowledgeBases notes, USB hardware is not supported under LabVIEW RT and having USB enabled in RT tends to introduce jitter to your RT application:
    Does LabVIEW Real-Time Support USB Communication?
    Too Much Jitter When Running a LabVIEW RT Application
    Hopefully, this won't be too detrimental to your application. If you are looking for a way to accomplish something without using USB you may want to post some details of what you are trying to accomplish. This forum would hopefully be able to guide you toward an alternative method of accomplishing your goal.

  • I bought a 3rd ipad for my daughter in CA. I synced w/my PC to load some apps since she has no PC. Now I am in Iraq with PC and my iPad. If I buy my her iTunes gift cards, can she buy apps and music w/out using my pin and charging to my Credit card?

    I bought another iPad for my daugther.  Because she has no PC, I loaded her iPad with apps from My PC. Now she is in Oceanside CA.  And I am in Iraq with my iPad and PC.. My question is: How can my daughter load some apps of her own?  If I buy her iTunes gift cards, can she redeem them on her iPad with out using my Pin number (as that would give her access to my credit card)! I prefer to gifted her purchases, not allow her to purchase with access to my credit card. Can this be done?

    well if the ipad is on your itunes account then her apps and music etc will be billed to you. but if you give her gift cards you should take off your credit card because itunes won't tell you when you are all through with your gifted money and are back to useing your credit card until after you have made a purchase

  • How to setup the windows installed pxi to RT target

    how to setup the windows installed pxi to RT target?

    Ranjith,
    I think the answer for your 1st que is NO. In the sense, you can run the code, but it may not work precisely as it is supposed to...
    A target can be said to be an RT, if & only if it has an RTOS installed in it, not just Windows, which is not a real-time OS.
    Youcan run the existing code in Windows, but as I said earlier, it may not give you the actual results.
    Finally, hereafter, pl dont use the term 'box' for a PXI. It is a chassis with a main module that runs on Windows or an embedded RT processor/conrtoller that runs on an RTOS like VxWorks or Phsr Lap.
    Hope this helps you to some extent...
