Trouble using DAQ devices

• data transmission between the General case and problems of timing instructions using daq devices

  I'm currently developing a program using LabView 2012 SP1.  I am interfacing with an NI USB-6009 data acquisition using NOR-DAQmx 9.5.5f4.  I'm trying to get a voltage on the three analog inputs (AI0 and AI3 AI4) 1 second to start and 20 seconds of starting.  Three digital ports: P0.0, P0.1 and P0.2 are used to market the transistors for the signals in question and must remain high to the course of ~ 20 seconds the readings will take place.  After 20 seconds, I need to take the readings of each analog channel and the difference of the two to determine the delta at the start.  This delta will lead logic to implement later.  The attached VI has a while loop that runs on an interval of 1 second and a case statement that takes a reading DAQ at 1 second and 20 seconds (two separate trials).  The while loop stops after 21 seconds.  The question I have is how to manage the tensions of reading of the second 1 case and the second case 20.  I need to take the difference and the exit to the front after 20 seconds elapsed.  Please keep in mind when you answer that I am relatively new to LabView.  I have experience with several other languages (Matlab script, C, Java, Perl, etc.), but am still learning how to get concrete results in LabView.  That being said, guess I know nothing outside of what you see in this VI.  If you have any recommendations on how to implement more efficiently, I am open to suggestions. Thanks in advance for your help.

  I would make the acquisition of 21 seconds of a value of data from data acquisition.  Then, you can index you want specific samples.  Have time to wire samples is much more reliable that Windows hope will be both properly 21 seconds.  It also simplifies the code in a bit.

• without using DAQ how a PID controller for temperature control

  Mr President.

  IAM trying to make a PID controller for temperature control in labview. But I have no devices data acquisition. Then without using DAQ how a PID controller.please suggest some useful block diagram.plz give me an answer. I tried one, but not working.below attached is my work.

  as a learning exercise, some devices can be simulated in the Explorer to measure (performance measure explore, right click on devices, select Create new.) Select simulated device and choose your device, you can search by product code for example 4070 for a dmm)

  I hope this helps you begin to learn labview, depending on how advanced you can I strongly suggest looking in training of core 2 and core 1 but also by looking at the examples that come with labview

• Different value of USB DAQ device on different computers?

  Hello

  I have not found an answer to this one, so I open a new question. Here's the problem:

  I have a card OR USB 6003 and I read some analog signal of a sensor with a framerate of 1000 Hz (I use actually 4 analog inputs for 4 sensors). I created a VI and everything works fine on my computer. Then, I created a standalone application (.exe) and the installer that includes the drivers for the hardware DAQ and LabView Runtime Environment. When I install everything on computer target, the program works, but the sensor readings are weird! For example: I get a reading of 1 bar with a deviation of 0.02 bar on my original computer. When I plug the device on the host computer, I get an average reading of 1 bar with a gap of 0.5 bar, which is a lot! This gap could be considered some disturbances high frequency - like noise. What could be the problem? Is this even linked with LabView or is it hardware problem?

  OS information:

  Win 7, 64-bit (my computer)

  Win 7 32-bit (host)

  News of LabView:

  LabVIew 2013, version 13.0f2 (32 bit)

  OR MAX version 14.0.0f0

  Setup includes:

  NI LabView Run - Time Engine 2013 f2

  NOR-DAQmx run 14.0

  Thanks in advance on this one!

  Best regards

  Geraldine

  If you run the Test NI MAX Panel on each computer, you get the same result? Way that you specify which device to use in your code (for example MAX tasks? Project tasks? DAQmx configuration screw?) and the devices have the same configuration? Are you using the exact same device USB 6003 or use a different one on each PC?

  A computer is a desktop computer and another laptop? Economic DAQ devices are not isolated, so you could get the sound of your PC power.

• Trouble using NI USB-4065 with virtual machine VMWare

  Hello

  I'll be working with a virtual machine (windows xp) and I need to use an NI USB-4065 DMM.

  When I connect the USB-4065 to the PC, the virtual windows xp recognizes the new HW and also MAX display the new device on the list DAQmx.

  It seems ok, but if I try to use the USB-4065 (open the soft cover or in a LabView VI), the device does not work.

  If I use the frontpanel app, when I click a botton, the Group seems to work but doesn't measure anything; If I try to reboot the softpanel, it works and 'freeze' of the screen.

  If I use LabView, the VI returns an error on a maximum duration of the measure.

  I'm trying to use the device on the real machine (not with VMware) USB-4065 works, whith flexible Panel and whith VI.

  I update the driver of the DMM on the virtual machine, beats the device still doesn't work.

  ... I don't have any other idea, can anyone help me with this problem?

  Thanks, SEM.

• use of devices high cRIO 9068 FPGA

  Hello. I have problems with my cRIO 9068 (dual-core, Artix 7 667 MHz), which uses a lot of FPGA resources. I did a little VI FPGA (LabVIEW 2013 SP1) allowing USER FPGA led to two colors (green and orange) for 500ms and then it is off for another 500ms. use of device Watch report 9193 records used(8.6%) and 9744 LUTs (18.3%). I adapted the VI even for a cRIO 9072 (Spartan 3 - 1 M) which have been allotted to me and use of the device is much lower: registers used: 443(2.9%) and read: 644(4.2%) - please see attachments!

  I used the XNET library in the past with the 9068 and 9862 CAN Module: since I knew that these libraries use the FPGA space, I removed XNET 1.8 cRIO software before this test. Before removing, use of FPGAS was even higher!

  Can someone tell me how can I reduce the resources used to 'normal '? Thank you!

  Hi Lucien,.

  The increase in the use of core resources that you see is normal for the family of targets Zync. Try to compile white VI for each (no user written code LabVIEW). You will notice that the Zync platform always uses an important part of the fabric (which targets Zync is used).

  This behavior is due to the very different architecture of the family of chips Zync. As the FPGA and ARM processors are on a shared matrix, a large part of the logic and OR treatment implemented in ASICs Spartan/Virtex advice should be moved on the FPGA itself.

  You should also notice that, although there is an increase in the use of FPGA base fabric, the gross number of LUTs/flip flops at your disposal as a user is much greater on Zync objectives than a Spartan comparable unit.

• T520 will not use any device DVD

  People,

  I was going to do a backup, when I noticed that the DVD player was no longer under my computer.

  I when in Device Manager, where he showed with a yellow X... I tried to update the device driver, it said that I had the right device. I've done many other things - nothing has worked.

  I really wanted to get the backup made, so I took my portable DVD player/burner and plugged. The laptop computer found a loaded device OK... but it does not appear in my computer. I had the same problem as the DVD drive internal.

  Then I got a USB drive external Passport, connected to the same USB port, no problems... He mounted the disk and I made the backup.

  My T520 will not use any device DVD... ideas?

  I did a quick search and voila. See the Windows 7 box.

• This device cannot find enough free resources that it can use. If you want to use this device, you will need to disable one of the other devices on this system (Code 12)

  Guys, I have a problem. So, my laptop has 2 graphics cards, an integrated course of the Intel HD graphics (which works perfectly) and the other being the dedicated Nvidia graphics (Nvidia GeForce 940 m). Until 2 days ago, everything was going well and running.

  I have the application experience GeForce and it prompted me that there is a new driver update should I download. He started to install then after rebooting to complete the installation, it failed. I checked my device manager and saw a yellow exclamation under under my Nvidia graphics card (remember, my laptop has two graphics cards: Nvidia graphics card and Intel HD graphics that works correctly). I immediately checked the details, and he said:

  "This device cannot find enough free resources that it can use. (Code 12) »

  "If you want to use this device, you will need to disable one of the other devices on this system."

  This seemed very strange, because it was LITERALLY working properly before I was invited about update driver I got, so I don't know what to do - as a matter of fact, literally, I finished this game, Deadpool, with my Nvidia card that I put as the default graphics card, a few hours before , so I don't know why this happened. Any help? I'm looking for a logical answer to this, guys!

  Additional information:

  A few days before this happened, I went to my store local pc and installed an extra 4 gigs of ram on my 4 existing to make 8. Don't know if it's useful, but anyway

  If I pick up my laptop and shake it side by side, I hear a slight rattling noise, and it seems a little loose (I found this out after seeing the error message). The noise seems to come from just below the middle of my keyboard (I'm using a laptop). If for some reason, my Nvidia card is loose? Is this possible?

  I am quite technologically inclined, but not to the extent of removing components and reconstruction cell phones / pc and access the bios and what not. I can only remove/add ram.

  I want to know if its something I am able to fix it because I do not necessarily want to go running and sending my laptop places - only my pc up shop.

  Here is the location of my Nvidia card: PCI Slot 4 (PCI bus 4, device 0, function 0)

  My specs:

  Acer TravelMate p257-MG

  Windows 7 business

  Intel core i5-5200u 2.20 GHz 2.20 Ghz processor

  8.00 GB of ram

  64-bit operating system

  1 t hard drive

  940 m Intel HD graphics 5500 & Nvidia Geforce card

  Just to recap, I get the error on my Nvidia graphics card code, "this device cannot find enough free resources that it can use. (Code 12) ""If you want to use this device, you will need to disable one of the other devices on this system. »

  Thanks in advance!
