Digital triggering PCI-6024E problem

• Incorrect, test the results of the e/s digital PCI-6024E in MAX

  Hi all

  I have a problem with PCI-6024E. It is for the Commission alone OR installed on a target computer. First he just used OR-traditional DAQ (7.1, if I'm not mistaken) and it worked fine. Some time ago I installed NOR-DAQmx 8.7.1 on the same computer because it is necessary to run both programs written with NOR-DAQmx and NOR-traditional DAQ. As I know there is no harm to do both OR-DAQ and NOR-DAQmx on the same computer if they are not used at the same time. You can see the traditional under NOR-DAQmx devices and peripheral branches DAQ PCI-6024E jury in MAX. When I run the self-test, self-calibration or Reset Device, Max there is no problem. But Test panels (under the direction of NOR-DAQmx) has a rather strange behavior. When I press the "Start" button in tab e/s digital Test panels window with all the digital lines in input, the 4 first green indicators are on and the other 4 are not. And then nothing happens or I press the 'Stop' button or not. I have the same card as a virtual in my MAX on a development computer, and there is a different behavior of it (I don't have traditional DAQ here, just the same version DAQmx). During the entire procedure of test until I press the button 'Stop', the port State 8 lines constantly evolves so the Green indicators are switched on and off with different ways through all possible combinations of logic '1' and '0' in each line of the port.

  The problem is really obvious when trying to control the statements of some laboratory equipment using their passage through PCI-6024E. digital controls. In this case I get auto turn on/off devices connected to the first 4 lines (which are always lit for some reason any as stated that the Green indicators).

  What should I do? This means the Agency is malfunctioning or there is some conflict of data acquisition and acquisition of data-mx? I would try reinstalling DAQ - mx, but I don't think it's a way out of the situation. I work under Windows XP SP2.

  I appreciate all help.

  Igor-

  Your digital outputs will remain in their last State configured unless the device is reset, in which case they will go to the default value (high, in this case).  So if the last State of the low output of your digital program, as long as you do not call the Device.vi DAQmx reset or shut down the computer, they will remain weak.

  If you have other questions about this application in LabVIEW, it would be better to create a new post on the forum so that we can keep these two separate issues (States of I/O digital by default against digital programming in LabVIEW).  If you are looking for a starting point, you can open the Finder example in LabVIEW ('Help' to find examples).  "" Once the example Finder opens, click on input and output material"DAQmx ' digital generation ' write Dig Chan.vi.  This will help you start.

  Better luck with your request and have a great day!

• Slope of digital triggering NI SCOPE

  I have a problem, try to use a digital triggering with a USB-5133 digitizer.  I use NO-scope (3.5) and C.  My software doesn't seem to be able to change the slope of the trigger (using niScope_ConfigureTriggerDigital()).  There is no problem if I use an analog trigger.

  The problem is not related to my code.  I see the same behavior with the NOR-SCOPE Soft Front Panel (version 2.9).  In this application, if I connect the trigger PFI 1 entry and select digital triggering, then the selection of the slope has no effect.   However, by selecting briefly "edge" trigger, change of slope in this mode and back to digital triggering, I find that the trigger is now working according to the slope in the edge, trigger mode.

  Although niScope_ConfigureTriggerEdge() seems to work o.k. (using an analog input) and is not niScope_ConfigureTriggerDigital(), the following sequence does not provide a work around:

  niScope_ConfigureTriggerEdge (...);

  niScope_ConfigureTriggerDigital (...);

  The entrance of IFP 1 seems OK, even though at the start I had been feeding it straight V CMOS 5 door.  Adding a separator line at the entrance to the tensions between 0 and 2.8 V had no effect on the behavior.

  Hello Bmetz,

  It is a known problem that has been fixed in version 3.5.1 OR-scope. You can download and install the update through the page drivers and updates here:http://joule.ni.com/nidu/cds/fn/p/sn/n23:3465.40/lang/en

• Simultaneous use of PCI-6024E (former) and BNC 6210 (new) possible?

  Hi all

  I've updated to NOR-DAQ 8.9.5 to get the job of BNC 6210. I also have an old 6024E PCI installed. After the update, MAX shows the PCI-6024E and all tasks configured for this device with a little red cross. The tasks do not work (error-200477 message: no devices configured), and while I can choose the PCI-6024E or-Daq, the button for etc test panel is grayed out in the devices section.

  According to the NOR-DAQ 8.9.5 readme, both the 6210 BNC and the PCI6024E are supported for my XP system.

  Clues as to how I could get both work?

  Thanks for the reply. I solved the problem by uninstalling OR-DAQ 8.9.5 and installation 8.9 (because 8.9.5 wouldn't work with my LabView 7.1). Now, the two devices work fine.

• digital triggering of stop/start of analog data acquisition

  I want to use a signal from a digital line to start and stop analog data acquisition. The signal can change levels several times during a race of the VI so I have to start and stop several times data acquisition and store each session data in a different file.

  I tried to play with the following screw: digital triggering of break, DigitalStartandStopTrigger and ContAcq_DigTrig. None of them doesn't seem to work for my configuration. I also do continuous data acquisition so I can't use a reference. I use PCI 6259 DAQ.

  I used the "P0" pins rather than PFI pin on the grid BNC-2090. I know... stupid enough.

• Outbreak of the AO tasks with digital triggering

  I'm triggering an analog using a digital triggering (PFI0) task on a NOR-6343 (USB), but don't see the behavior desired of my VI (see screenshot).

  * When I shoot digital triggering (digitalTrigger = False), the AO signals appear planned (except that... they do not fire).

  * When I turn on the trigger (digitalTrigger = True), however, there is no signal on the channels of the AO.

  * I tried two different sources: PFI0 and the clock internal (set both rising edge). For the PFI0 channel, I connected a function with a wave generator square 5 v (the PFI0 had a slow rise... time "I think I could solve this problem by adding a small circuit of buffering). However, I expect it should work correctly using the internal clock as a trigger.

  What's wrong with my code / setup?

  A few follow-up questions:

  * This will trigger the installation program not start indicator AO once? Or the trigger will cause the task to start whenever the finished AO signal and the trigger goes high? (I wish that it behaves like the latter)
  * Just to check: the response rate of the AO task to the digital trigger should be of the order of 1 MHz?

  Hello kllurie,

  What do you use the trigger for? The way you have the task to put in place now, it will run continuously until you press the STOP button and ignore any input trigger. If you want to be able to have the task to complete and start over with a digital triggering, you make the task two finishes and Retriggerable. You can configure the task to be finished by replacing the constant continuous samples on the Timing.vi with finished samples and giving him a number of samples to be taken before stopping. Then you can do the task Retriggerable using the property trigger DAQmx node and choosing Start > more > Retriggerable sometime before the Start.vi.

  As to what it should be used as your relaxation, you'll want something with a fast rise time (so that it is detected as a numerical advantage) and is not as fast as the sample clock. If you use the sample as your trigger clock, there would be essentially no difference between your redeclenchables task and a continuous. It would end the collection of samples and then immediately redeclenchee.

  Let me know if that answers your questions!

• NI PCI - 6024E and virtualization

  Would it not possible to use NI PCI-6024E in a virtual environment? For example, could I install the card on a Hyper-V host and power in interface with a virtual PC running on this host? Is there a driver for this card that would allow me to do this?

  Hello tylertx,

  I say that it is technically possible, but it's more a question how to assign a specific PCI slot with a virtual machine.

• generate a digital triggering out CH1 (low and high) for the USB-5133

  Hello

  I would like to generate a digital triggering on the USB 5133 CH1, is this possible?  I tried with the PFI 1 successfully but the output is only 3.5 v and I need to 5V, because this trigger signal goes to a box of pulse generates a signal, which is received by the CH0 on the USB-5133. This configuration works on the 5102 OR but because of the treatment, I am obliged to try a new device.

  Channel 0 and 1 are only entries then you will not be able to use them to generate a signal.  All of our products current digitizer that are recommended for new designs use 3.3V CMOS logic levels for PFI lines in output mode.  Your best bet to generate a digital triggering 5V would be to use an external buffer that can accept 3.3V CMOS levels as an input, but is under voltage of 5V.  Here are some that might work for you, but there are many others: http://www.onsemi.com/PowerSolutions/product.do?id=M74VHC1GT126DT1G adding a buffer in line with the trigger signal will add delay, so you will need to ensure that it is acceptable for your application.

• simulateneous of analog and digital triggering

  Hello

  I have an experience that is very similar to this announcement:

  http://forums.NI.com/T5/LabVIEW/how-do-I-reset-the-arm-trigger-with-DAQmx/m-p/2006639/highlight/FALs...

  As in the display, I need trigger out of logic AND low frequency (3 Hz) and a signal of high frequency (100 Hz).  However, my experience is different because my low-frequency signal is an analog of entry (AI0) and I need experience to trigger off each edge of the signal change high frequency, while the analog input is high.  To do this, I created a trigger to HAVE that starts a counter whose state high and low are similar to that of my analog input signal.  I then export the output event from the meter to a port (PFI8) and pass this signal and the other signal high frequency through a door AND as in the posting linked above.

  So far, everything works.  I've included a VI that is just this part.

  However, I then connect the output of this gate AND a PFI0 port and use it as a digital triggering to read an AI0, 1 channel.  When I perform this final step, my whole system stops working, but gives no error.  To troubleshoot, I measured the output of the meter to the port of PFI8 has stopped working and the port of PFI8 remains in the low state.  For some reason any when I add the channel HAVE additional (AI0 or AI1, whatever) with digital trigger (PFI0), everything grinds to stop.  I have also included the VI for this case.

  Any ideas?

  Thank you very much!

  Hi Jared,

  I use indeed a door AND external as described in the thread.   Further research actually led me to discover that "you can't have two analog input tasks at the same time" of this thread:

  http://forums.NI.com/T5/Multifunction-DAQ/multiple-analog-inputs-by-multiple-digital-triggers/TD-p/1...

  So I had to build a circuit to convert my analog signal into TTL signals (for the release).  I then AND'ed the two signals in the same was as described in the thread mentioned above.

• How the pressure transducer Validyne system-> Validyne CD280-Dual-> SCB - 68-> PCI-6024E-> LABVIEW works and how we can calibrate the pressure sensor?

  Hello

  I am completely new to LABVIEW software.

  I learn a LABVIEW code existing my pressure (attached) acquisition system which has the path of data as follows: pressure transducer Validyne--> Validyne CD280 - Dual--> SCB - 68--> PCI - 6024E--> LABVIEW and I have a few question:

  1. How does the complete system of the transducer to the LABVIEW work? That is, if we apply the pressure of the transducer, it will change the resistance of the probe then...?

  2. How can I find the equation that expresses the relationship between the pressure and the tension to the keys of the Validyne double-CD280 in the LABVIEW?

  3. If I want to do the probe calibration, what are steps?

  Thank you

• Problem - edges of digital triggering slows down during the fast rotations

  Hi all. I have problem to understand. I want to measure the pressure with two strain gages on 90 degrees (NI 9237 half bridge II) and I engine with metal plate on it with 52 teeth (gear) to measure on each tooth of the strain. For the rotation, I use NI 9401 digital input.

  I need for example 1000 samples from the first digital edge to the second. (on the metal plate). I try to start trigger. In slow speed (turn around with the hand) of the metal plate, everything is OK. But if I turn around the metal plate digital fast triggers edges slows down. During a cycle on the metal plate on the cost of slow speed me 52 digital edges 1000 sampels by edge (metal plate is with 52 teeth), but rely on fast speed on me 25 edges. This problem is sync of the digital inputs and the analog inputs. I made the example with DAqmx Vi express. I've implemented on digital imput and then count me in each tooth regardless of speed and everything is OK, but when I buid trigger of strain on the edges of quick release rotation speed slows down.

  Can someone help me with this?

  Thanks before.

  So you're collecting samples from 1000 to 10000 samples per second. Which takes 100 Ms. If your triggering edges occur more quickly than the interval of 100 ms, some of them will be missed.  If you run faster than a cycle all 5.2 seconds your gear plate with 52 teeth, some triggers will be produced before the end of the previous data collection.

  What is the fastest speed that you will not sping palte metal?

• Problems of digital input PCI-6143

  I hope it's good advice. I asked in software digital I/o and LV advice because I didn't know if it was etc. MAX, material. No one has all the answers. Before you fight on the repeated posting please reallize that my messages were for 5 days and the only questions answers to which I responded later.

  Card PCI-6143 bed not any signal PFI and yet he successfully uses the PFI signal to trigger the meter on board. All of the lines indicate a high signal although there is none. What does that mean? This indicates a Board fried or are there other possible answers. I had suspected MAX but I plugged my PCI-6211 and it works fine. This test through MAX test panels.

  Help, please.

• Generate the AO with digital triggering

  Hello, I have a problem, generate a continuous waveform (custom channels multlisample) when a TTL - as 5V 0V trigger is applied to PFI0. The problem is that synchronization source is running continuously, when the digital voltage line is connected I don't have to keep a single waveform sent, as opposed to a regeneration of the same waveform.

  I have worked with some conditional loops, but nothing works, is there a solution that can provide two triggers (one for a pulse train) and then for the digital falling edge (on 0V) which can allow the regeneration of the writing of the AO?

  Thank you

  DB.

  Hey DB,.

  I recommend using a pause trigger.  This will allow you to exit when a certain level of TTL is high (or low) and not when the opposite is true.  Here is an example that illustrates the break trigger using property DAQmx nodes.

  You need to change the time by continuous for this example sample clock, but also to change the data to be written to fit your application.

  You can leave the writing of the initial value in the analog output channel if you wish, or you can delete the original entry, start and stop functions DAQmx.  Either will work.

  Best,
