• PXI-8250 in one frame other than the 1042/1045 or PXI-1044?

  The PXI-8250 will work at any level in one frame other than the 1042/1045 or PXI-1044?

  Hi djfrye.

  The PXI-8250 can only be used in the 1042 / q 1042/1045.  It will not work in the PXI-1044.

  Good luck with your application!

• Synchronization of multiple unit with the PXI-1044-6250 M-6143S

  Hi all

  I have a problem with several device synchronize with my PXI system: when starting a measurement, the devices do not start at the same time despite using a trigger to start. The delay in the start time varies randomly between 150 nanoseconds and about 80 milliseconds.

  My PXI system consists of the following:

  • Controller PXI-8108
  • Chassis PXI-1044
  • 6 * Series S PXI-6143 (Slots 2-7)
  • 1 * Series PXI - 6250 M (8 slots)

  The software in use is LabVIEW 8.2.1, NOR-DAQmx 8.9 and MAX 4.5.  "The trigger line routing" is set to "Dynamic" for all 8 lines.

  I created 3 tasks in the attached VI: task 1 ('Drehimpulsgeber' = encoder, 1 channel, rate: 1.25MS / s), task 2 ("Heißfilme 1-8" = hot-film probe No. 1-8, 8-channel, 250 ksps through rate / s) and task 3 ("Heißfilme 9-16" = hot-film probe No. 9-16, 8 channels, rates by way of 250 ksps / s). 3 tasks are expected to start at the same time acquire the analog voltage by pressing the button "Start". "." As the trigger for the beginning, I use a digital pulse created on/PXI1/PXI_Trig0.

  After reading samples, the first timestamp recorded for each task is retrieved, displayed and the delay time is calculated (see boxes 'Start time' and 'Time Delay' on the front panel).

  How can I optimize to synchronize the start of all three devices without getting this random delay?

  Thank you in advance.

• How to set up the PFI lines as input to PXI-6713 module

  Hello

  I have 6713 PXI module in my chassis PXI-1044. I have configured the PXI-6713 module to geneate some analog signals to my Board of Directors.

  Council inturn process this analog signal and answers in return the status signals through a registry to the Board of Directors. In my application, the status bits in the register state of the governing body are mapped on the PFI 0:3 bits of the PXI-6713 (pins 11,10, 42 and 43) module.

  My query is how can I configuration lines PFI as 6713 PXI module entries to read these status bits?

  May be less than the explanation could give you little more information w.r.to my request.

  When I use NI USB - 6008 module to read the same bits, because this unit has 12 e / s digital, I was able able to read the status bits in the last 4 digital lines by setting up those digital lines as input.

  In the PXI-6713 module, I have only 8 digital lines. These 8 digital lines I used to send digital signals to the Board of Directors. I find myself with no digital i/o. Therefore, I could not use these digital lines. I'm left with only one option to use. Joana re PFI lines. Also the bits of status in the axis of the room are mapped such that the bits can be read through the PFI lines.

  I was wondering do we have any example code to use inorder to read these status bits to the Board of Directors using the PFI lines.

  Please let me know if you need more information to help out me.

  Thank you.

  Hello

  When using the PFI PIN as input, you can individually configure each PFI for edge detection or level and the selection of the polarity.  This information of PFI are referenced in the manual of Series DAQ Analog Output on page 6-1 (http://www.ni.com/pdf/manuals/370735e.pdf).  Unfortunately, the PXI-6713 PFI lines are able to time a signal input and output for functions, AO or counters/timers.  The ability to create static DI of the PFI lines is not available for the PXI-6713. However, some cards have this capability.  The latest National Instruments products with PFI lines have the option of setting as PFI lines:

  1. Static digital input
  2. Static digital output
  3. Input signal of sync for functions HAVE, AO, DI, or counters/timers
  4. Output signal of the calendar functions HAVE, AO, DI, or counters/timers
     (http://digital.ni.com/public.nsf/allkb/14F20D79C649F8CD86256FBE005C2BC4)

  When the static value such as DIO, PFI lines are assigned to a different port (for example. PFI0-7 is Port1).  More details on this subject can be referenced at:

• How to synchronize the start of IT and relaxation the Scan list (DAQmx Switch)

  Hello

  I want to measure samples of N to the AI0 of Council NI PXI 4461. The measurement starts on a rising edge of a digital triggering provided to the PFI0 of the same Board. The measure is configured with samples of N/2 pretrigged. So far, everything is under control...

  Using an NI PXI 2567 Board, the signal applied at the entrance the 4461 (AI0) switches between a V2 and V1 signal. I would like to synchronize the switch between the two signals with the trigger signal applied to the input of the PFI0 Governing Council 4461. In order to obtain samples of N/2 of V1 and V2 samples N/2. Synchronization of 1 to 5 ms would suffice!

  My question is how to synchronize the start of acquisition of AI pretrigged of 4461 with the switch control given by the Council of 2567?

  Thank you in advance for your help...

  PS: the configuration of the system is:

  -LabView 8.5

  -Chassis PXI-1044

  PXI-4461 on slot 2

  Module 4-slot PXI-2567

  Hi Frederic,.

  I came back to this recently and used the following examples to run the desired synchronization.

  PXI-4461: Acq & graph tension-Int Clk - dig Start & Ref .vi

  Samples per channel = 1000

  Rate (Hz) = 10000.00

  Start the trigger Source = / [name of the instrument DAQmx] / PXI_Trig0

  Onboard start = fall

  Reference Source Trigger = DAQmx Device Name] / PXI_Trig0

  Reference edge = fall

  Trigger samples = Variable (100, 500, 900)

  PXI-2567: Switch Scaning-SW Trigger.vi

  Advance the output terminal full = / [name of the instrument DAQmx] / PXI_Trig0

  Scan list = / [name of the instrument DAQmx] / ch0-> com0.

  Scan list = / [name of the instrument DAQmx] / ch1-> com1;

  Hardware configuration:

  The PXI-2567 module controls an external relay that switches between the voltage of 5 V on ch0 and ch1 0 V.

  The PXI-4461 connects to the COM of the external relay and therefore reads 5V when ch0 is connected; 0 v when ch1 is connected.

  Procedure: The above examples are used in the following procedure.

  1. run the PXI-4461 VI.  A start trigger (falling edge) is necessary to start collecting samples before firing.

  2. launch the module, PXI - 2567 VI.  When ch0 is initially (and immediately) on com0, a trigger is sent to PXI_Trig0.  The PXI-4461 will begin to acquire samples before firing.

  3. - click on the "Connect to the next" button on the front of the PXI - 2567 VI module.  This sends a trigger to entry software for the PXI-2567 module and the transitions of the scan for ch1-> com1 list.  Once the PXI-2567 module remains (debounced), advanced complete relaxation is sent on PXI_Trig0 for the PXI-4461.  The PXI-4461 will begin to acquire samples after outbreak.

  Note: Instead of the trigger of the software entry, an external input trigger can be used (e.g. PXI_Trig1).

  Results:

  > Before instant release of samples = 100

  Delay is caused by the time of actuation of external relay.

  

  > Before instant release of samples = 500

  Delay is caused by the time of actuation of external relay.

  

  > Before instant release of samples = 900

  Delay is caused by the time of actuation of external relay.

  

  I hope that the attached screws and the explanation above helps you and/or other customers who have this problem.

• Read Calibration expiration with Labview

  Hello everyone,

  I found a way to read the configuration of my PXI-1044.  I would read the section external calibration of the Calibration tab in MAX for my PXI-5114 and PXI-4065 (last calibrated and recommended the next Dates of calibration) using Labview to read.  The preferred format, I'm looking is similar to the configuration of my PXI-1044 which retrieves data in a format delimited by tabs.  Thanks in advance for any information that can throw this forum on this topic.

  Kind regards

  Hi Dennis,

  Thank you for your most recent reply.

  Thanks for the vi.  I tried on one of the systems and other that it could not find the Initialize.vi, I replaced with one that is the measure of e/s > System Configuration, it will do the job and data retrieval will not be a problem.

  Many thanks for your efforts to help me better understand this particular function and please pass the file.  I consider this closed post.

• Export of Configuration MAX?

  I just don't understand?

  What is the point of the feature to import/export of Configuration MAX and why my version of the installer allows (not need) to set?

  We have a project that has been developed on a chassis NI PXI-1044. He now resides in a configuration management system, and sometimes we want to remove to make changes and build on a system that now knows nothing about PXI/chassis/controllers/etc, etc. In fact we have more material. But this Configuration hardware option within the construction of the Installer seems to require a configuration by MAX file on the host system used for the generation of the project. Is no longer the PXI-1044 chassis but another PC altogether.

  Why is this hardware configuration option exists? What is its usefulness when it comes to the installation of an integrated (such as an installation program) project. Why I can't live without it?

  It is perhaps a fundamental issue, but it makes no sense to me. I come from a background of the conventional script-based programming (C / C + c++ / Ada etc.).

  Thank you.

  The hardware configuration is not at all unique to LabVIEW and you also use it with all the other languages where appropriate. The configuration includes the names of devices, custom scales, tasks, etc. Include you the configuration that you have created on the original pc or recreate it on the deployed pc. If you have not used MAX for any configuration, so you do not need to export/import but correct detection name, scales, etc. have all be integrated into the program itself.

• Some or all of the requested samples are not yet acquired: API change responsible?

  My Delphi program, which works very well under NOR-DAQmx 8.9.0f4 on a set of material, fails under 9.0.0f2 on what I received insurance material is equivalent. The error is «some or all of the requested samples are not yet acquired...» ». This happens even to slow scanning rates, and coming to suspect that the API has changed subtly in the transition from version 8 to 9. What is the probability is it? Now that I have access to the source code on the new hardware (NI PXI-1044 with computer integrated PXI-8110) is there something I can do to check this?

  Hi Francis,.

  Your program still calls DAQmxCfgDigEdgeStartTrig() for all the tasks of the slave? If you do not do this, the devices are beginning to acquire data at the same time, and since you pass 0 for the timeout parameter to DAQmxReadBinaryI16(), out-of-sync devices could certainly time-out errors.

  In addition, you must ensure you start the slave devices before the master device, so that they're already waiting for a trigger at the start of the master device.
