• Need help with counters on PCI-6221 (37-pin)

  Hi all

  I have a system with a PCIe 1429 connected to a Basler A504 camera and one I use a clock generator (SRS CG635) of 3.9 kHz for trig the image acquisition.

  On the same system that I need to add a PCI 6221 37
  PIN to acquire:

  -2 HAVE 39 kHz, synchronized with the acquisition of the image. (Sample of the 10 for each image)

  -1 meter to measure a frequency

  The accuracy of my clock of 3.9 kHz being much higher than what I have on the DAQ card, I thought that an interesting option would be to have a redeclenchables DAQmx task that generates impulses from 10 to 39 kHz for each pulse received from the clock and then use it to trigger the DAQmx AI task.

  Of course this can only work if the 'trigger' sources that I defined for these two tasks do not take both counters that I have on the card.

  So, let's describe the DAQmx tasks:

  -Here is the one who generates the 39 kHz on 0, the counter of the 3.9 kHz I entered as a source on PFI 4 trig

  

  -This is the task of analog input for which I put the trigger on 6 PFI.

  

  It is: I have "softwarely" know the jury to deliver output (Ctr0) 6 FBP counter? And if so, how?

  Thanks in advance for any help!

  Maybe you missed something that I didn't really point out in my post.  The method I described would use the external clock of 3.9 kHz precise as a sample clock, so you would * not * be in danger of loss of synchronization in 1 s per day.  You need to only son of this clock signal in a stem of PFI available and configure the task to HAVE it as a result.  The 80 + kHz clock that controls conversions within each sample cycle * would * be generated by the jury of 6221, but he don't would not accumulate any out-of-sync error because he gets "retriggered" on each edge of the 3.9 kHz precise clock.

• Generate the train of pulses with counters

  Hello

  IAM using PCI6023E data acquisition in labview 7.0.  I need to generate a continuous 5 kHz 1usec pulse train and I have exhausted my two counter/timers.  Can someone proposes how to generate a pulse train without using timers?  I/O maybe?

  According to the specifications, the 6023 has not all analog outpts. Quite difficult to use what you don't have.

• How to generate a pulse with the signal generator?

  Hello

  I would like to ask if anyone knows how to use the Elvis platform to generate a regulated pulse wave?

  

  It should look roughly like the picture above. A sine wave with the regulation.

  Anyone who can answer my question please respond to my post.

  Thank you.

  You are using LabVIEW to generate the waveform or using the Soft front panels? In LabVIEW, you can use the express VI generator function and specify the Type as "Sine". Then, simply change the amplitude of the sine wave. During the actual pulse, the amplitude would be what you want (i.e. 1 V) and while the pulse is idle, set the amplitude to 0.

  

  If you use the soft front panels, you can use the Waveform Editor to create a waveform that includes a sine wave for the length of your pulse and then the values of '0' for the rest of the time. Then use this waveform in the flexible front of the arbitrary signal generator. Simply create a component of sine as the first part of the wave and then add another element to a level DC '0' for the rest.

  

• Need of XLSX files tested to see if there is a problem with the content library

  Hello
  
  I have a file which causes an error when you use the library of Stellent. The file is a file XLSX and when we open and then save the file again, then does not cause the error. This leads me to believe that the file has been successfully created or something wrong with the library. More than likely it is the file. Is there any tool that I can use to test the file that will tell me what exactly is the problem? The file is automatically generated by a survey company. And so if we can show a problem with the file itself, then they will have to solve the problem in their autogenerator.

  Which, in my view, that we use it for is to get out of text or metadata files to create an index on the data.

  Yes, it's also OutsideIn. I believe you can use the SDK to export research.

  If I were you, I'd do some testing base of the new version and it doesn't help, create a service request in Metalink so that management can take a peek inside.

• I want to generate a pulse of a meter train and count the pulses with the other counter on a USB NI DAQmx 6259.

  
  

  Salvation;

  Here is the solution for your problem.

  The cause is that "Gen dig Pulse Train-Finite" uses Ctr0 both Ctr1.

  Please refer to:

  "When you do a finite pulse train generation, a counter generates pulse train, and the other counter generates an impulse that acts as a barrier to the first counter. If you change the pulse train to generate continuously or

  only generate a pulse, you can run two tasks of meter at the same time without error. »

  http://digital.NI.com/public.nsf/allkb/04BEDD9E9E91ED3486256D180048116D

  I used Ctr0 and Ctr2, jumping Ctr1 as it is reserved by "" Gen dig Pulse Train-Finite ". I works very well.

• Generate 2 Trains of pulses with different frequencies and Heavy duty with a PCI-MIO-16XE-10

  Hello

  I use a Board PEAK-MIO-16XE-10 DAQmx with LabView 8.6 to run a door for a piece of equipment controller. I need to create 2 separate, all pulse trains both trigger simultaneously, each with their own cycle frequency and duty. So far, I can create 1 pulse train and it works exactly as I need, however, whenever I try to enable the second train (called a door in this VI), I get an error saying: "the specified resourse is resevered," even though the first door is configured to use counter 1 and the second must be set to use counter 0. As I understand it, this map contains 2 separate counter/timer modules, so this should be possible. A large part of the rest seen in the attached VI's preparation for the signal processing and other controls that I use that I finished this VI.

  Thank you

  <><>

  Hi Eric - you forgot to attach your VI.  I did what you're trying to do with a similar card, but who has been using NOR-traditional DAQ (before DAQmx).  It should be possible with DAQmx as well.  A quick search on the forums turns up these two links, which suggests that your problem is that you try to create two tasks separate DAQmx, one for each counter.  What you need to do is create a single task DAQmx which includes the two counters, then together, that their frequency and duty cycle regardless.

• Can PCI 6602:How I use digital lines of the Board of Directors and at the same time to generate trains of pulses by using a meter?

  Hello!

  My problem appeared when I tried to update my traditional NOR-DAQ legacy code to DAQmx.

  I use 2 meter (meter 5 and 7 meter) on PCI-6602, to generate trains of pulses, as well as the lines of e/s digital port 0 (the form lines from 0 to 7). What I do in my request, it's that I'm starting to generate the pulse train on the output of 2 meters and after that I play with the State of digital lines.

  Traditional, it was no problem to use the meters and digital lines at the same time, everything went perfectly, but in DAQmx, is not possible.

  What's happening: I start generating train of pulses on the output of counters, no errors, but when I try to change the State of a line of digital port the generation of the pulse train is stopped. What happens when I start the task associated with the digital way.

  My question is: is it possible to create a channel on digital lines without changing the channels created for meters?

  Another thing that I managed to do with the panels 'Measurement and Automation Explorer' and Test for PCI-6602, is basically the same thing, I generate trains of pulses on the output of the 7 meter and try to start a job on the digital line, but I get an error:

  "Error-200022 occurred in test Panel.
  Possible reasons:
  Measurements: Resource requested by this task has already been reserved by another task.
  Device: Dev4
  "Terminal: PFI8.

  On the contrary if I use the counter 0 or a counter 1 to generate trains of pulses I encounter the same problem.

  What resources are used by 2 to 7 of the PCI-6602 card counters and the counters to 0 and 1 do not use?

  Thanks in advance for any answer!

  Ciprian

  After doing some real tests on this device, I found that it is a normal behavior for the jury of 6602.  This is because when you start a task digital all 32 lines are configured for digital i/o, so it replaces your meter operation.  The article below the link explains a little more on this subject.  You must start the digital task before the task of counter to use the features of both in your program.

  2 meter and above will not work correctly when you perform digital i/o on NI 6601 or 6602
