Restart waveform immediately start trigger

I create a waveform 50 ms with an SMU-5451 in SMU-1078 chassis with a controller of SMU-8840 running Labview RT.  The waveform is currently triggered by a pulse of a counter of data acquisition because the timing of the wave must be closely synchronized with data on the acquisition of data collection.  However, this approach is problematic because it is difficult to produce a continuous of the 5451 signal when it is triggered in this way.  If the waveform is exactly 50 ms long, will miss the start trigger.  I can tolerate losing at the end of the wave, but I can't tolerate having a gap in the output, and I need the waveform to start exactly on the edge of outbreak of 50 ms.  I can configure the 5451 to accept a trigger start and restart the wave immediately rather than wait for the current iteration of the waveform to complete?

I guess I could use a complete the 5451 event to trigger the acquisition of data instead, but I guess there is a way for me to do what I want.

Are you familiar with the mode "script"? You might be able to use this example script:

script restartWhenTriggeredScript
Repeat forever
generate wfm
break on scriptTrigger0
Repeat forever
generate wfm
end repeat
end break
end repeat
end of script

Basically, the idea is that, when it receives a trigger, it stops the execution of the inner loop and finish the iteration of the outer loop. Then it will start again from the beginning and to the inner loop.

Please let us know if that fixes the problem.

  • How to read a waveform beginning after trigger conditional

    Hi all

    I need to communicate with the PXI-6541 card with three sons.

    The installation is as follows,

    The first line is the trigger line. I need to wait until they get front down.

    The second line is the active signal line which is the card output line. I need to make this high with a certain delay line when I get the trigger.

    The third line is the row of data that I need to acquire by waveform playback.

    The problem is that when when trigger strikes, it begins to acquire waveform data, I need to filter later because valid data, it is only when the active signal line is high.

    So I want to get rid of data filtering.

    When trigger hits, data acquisition must wait an active signal to go high. Once he should start the acquisition.

    Thanks in advance...

    KAMRAN

    KAMIJI,

    Unfortunately, you will not be able to run different generation and acquisition to two clock frequencies without using an external clock any. If you look at the help of HSDIO Clock Sources summary , you will see that there is only one clock available onboard. If you need to acquire half of the rate, you will need to provide your own clock that runs at this rate. Now, you could take the clock generation and export this clock CLK ON DDC CLK or terminal TO terminal, and then use some external circuits divide the clock frequency in half and then import the clock signal in the STROBE line.

    Another option is to use a data line, and simply write a 1010101010 model. This would actually give you a clock signal which was half the rate of your generation on a row of data session and you could then this wire channel to the CLK or STROBE line and use it as a clock. It would take just allows you to use a channel more digital output.

    I would like to know if you have any questions about my suggestions. Thank you!

  • Start trigger

    I am a user of first of the NI USB-6361. I'm programming in .NET (c#) and using the NationalInstruments.DAQmx class.

    What I try to do is the following:

    Using a digital output port, generate a wave from 0 and count up to 31 and then stop with a power of 0. Each count is 12.5 microseconds long. This wave must be generated 15 times, once all the 1 millisecond. i.e. 15 waves to 15 milliseconds

    While this is happening, I want to taste a milliseconds of being digital to analog input 10 from the front of the output wave. To do this, I intend to sample the analog input to 2 MHz.

    I think I can manage the entry next analog examples. It is the digital out which I am having trouble with.

    I can see that if I created a table of 80 (1000 microseconds / 12.5 microseconds) values, beginning with 0, from 31 and the remaining values, the value 0. Then, I use this all the time with a clock of 80 kHz wave form.

    I want to know is if there is a more simple or more elegant solution. that is, if I wanted to easily vary the maximum number allowed (from 31) value or the number of waveforms must be generated (from 15).

    For example, can I use a redeclenchables to start a waveform finished?

    Or could I get rid of my wave form all together and use a counter?

    I don't know if these (or other) solutions would be appropriate, and how to put them in place. I have some difficulty finding appropriate c# examples.

    Any help would be greatly appreciated.

    Ah ok...

    If you think that this approach a bit more intuitive:

    Configure a continuous (or finished if you want to only repeat a number of times model) output of the frequency meter task want to knit the digital output.

    Instead of buffering the digital output with 0 task, to the end of the buffer with the 32 stamples (or however much you want to generate).  Configuration of the task to be "finite" and the number of samples that is equal to the number in your buffer (for example, 32).  Set up a trigger digital task start and use the meter's internal output the command source.  Set the trigger to be redeclenchables.

    Set the analog task was over and a length that interests you.  Configure the trigger to start the same that you have made to the task of digital output (including making them redeclenchables).  You can set the time between trigger start property to allow to enter your task to wait that long after the beginning of the output to start sequence to acquire.

    You can run the continuous analog input (using 0 as a buffer in your task of digital output as well) and avoid having to use the meter.  To make this work you have to synchronize the start of the tasks together (e.g. use the beginning of AI trigger to trigger the task of digital output) and then follow the number of samples on the enter task in order to know where the timing windows are that you are interested.  The calendar will not derive as each task derives its clock to the same time base (just be sure that you have selected the output rates that are divisors of 100 MHz).

  • 200077 error has occurred to the property trigger Node DAQmx DAQmx Start Trigger (analog Edge.vi:1-> CRT with trigger

    I created a program that reads analog data and draw a waveform, but I need to stop the program when the voltage drops to a certain tension. When I tried the analog edge trigger it showed the error in the subject:

    Reason: The requested value is not supported for this property value. The value of the property may be invalid because it is in conflict with another property.

    Property: Trig startup type

    Requested value: analog edge

    You can select: Digital Edge, no

    I understand what the analog trigger is not available for my DAQmx version, without again getting equiptment, can I use a trigger to stop reading data at a specific voltage?

    How to start and stop a similar read digital triggering?

    Thanks in advance!

    Ah! Well, then the Boolean value of status would be connected to the State of the thread of the unbundled error, Boolean stop to the stop button and the Boolean value to the right would be the stop for loop itself... so something like this (see image).  This is an excerpt from LabVIEW 2014, so it can not easily fall in your version, but I hope it's clear enough on how you can wire it to the top.

    Hello Ksin

    In my opinion, there is definitely a hardware problem. It is very interesting that your device starts correctly after 3 or 4 starting the process. Maybe it has something with the temperature of the material. It is really not easy to tell what the problem may be, but it is possible that by the high temperature of inter-connexions hardware is better and the unit starts correctly.

    As I said this is not explaining what can be the problem. In my opinion just service partner can check it properly.

  • Portege R500 - restarts instead of start, works only BIOS

    It's a great device, but atm I wouldn't money to buy a 2nd time... :-/

    Michael

    Hi Michael,

    It's really hard to say why this is happening and theoretically what could be the reason for this: bad drivers, virus, CPU, RAM, motherboard, etc.

    Before you think about exchanging your hardware, you must update the display driver. This is why start in safe mode and uninstall the display driver. After that, start Windows normally and try to install the new driver to display on the Toshiba site.

    You wrote that this also happens if you boot from DVD. Have you tested the Toshiba Recovery disk? Normally it it shouldn't t happen.

  • analog output digital start trigger the api c

    Hi, I'm trying to start analogue output based on a digital trigger (either PFIO or a PXI line) I can make this easy in LabVIEW.  However with the C API (through the Python wrappers), the problem is when I call DAQmxBaseWriteAnalogF64, writing will always be timeout that the acquisition was not triggered.   However, I can't call it after the trigger occurs, because obviously, it will be too late.

    I can't find any examples of C API where the analog output is triggered a digital triggering.  I can find for the analog input, but is fundamentally different that you can CONV read anytime after the trigger occurs.

    Python code as follows (functions are equivalent ot C API, even if you have no need of ot pass the task handle such that it maintained as part of the Task object)

    # create analog output task
    analog_output = Task()
    analog_output.CreateAOVoltageChan("Dev1/ao0","",-10.0,10.0, DAQmx_Val_Volts, None)
    analog_output.CfgSampClkTiming("",outputRate, DAQmx_Val_Rising, DAQmx_Val_FiniteSamps, numSamples)
    analog_output.CfgDigEdgeStartTrig("/Dev1/PFI0", DAQmx_Val_Rising)

    # create digital trigger function
    highSamples = 1000
    numpts = 3 * highSamples
    doData = np.zeros((numpts,), dtype=np.uint32)
    doData[highSamples:2*highSamples] =  2**32 - 1
    
    # send digital trigger
    doSamplesWritten = c_int32()
    dig_out.WriteDigitalU32(numSampsPerChan=numpts, autoStart=True, timeout=1.0, dataLayout=DAQmx_Val_GroupByChannel, writeArray=doData, reserved=None, sampsPerChanWritten=byref(doSamplesWritten))

  • PCI-6221 PFI0 start trigger is stray signals reading

    We have a card PCI-6221 attached to a SCB-68 in a control console, we've made dozens of times. However, this time, we will have problems with the beginning of PFI0 relaxation. Operation of the actuators 24 v remote (cable to DAQ card but operated through manual switches) triggers the beginning. We tried a shielded cable and everything is grounded. There is no parasitic voltage coming into the SCB-68 box. We sent also all the other analog I/o box. It's just the son of trigger start going. What is unusual, is that if we give a thread to the PFI0 (Terminal 11) who does not finish anywhere, we just hold in the air, do not cross any other thread, running our actuator valves still initiates the trigger. If we remove the wire, it does not raise. It's almost as if she receives wireless signals. But how wireless receives + 5V to trigger I don't understand. We also tried to use a spare PCI-6221, same known issue work. When you view the PFI0 in MAX, flipping the switch actuator will cause the counter generate 400 + charges. A normal release with our power switch usually generate 10-20-count indictment. We are really puzzled. Thanks for any help!

    Don't have not an answer to the first question, will have to research.

    THA Cabinet is wired the same, the only difference is that we added a transformer so that the system can run on the seas, but has not actually been hooked again, sitting in the Cabinet.

    Yes, we used a cable leading to one end. We tried the ground at both ends, the same results. I also waved to the cable in the air and a people in the head with it, it made me feel better.

    Don't think on the unused entries in the Earth. Personally, I think that the PFI0 is to be triggered with less than the + 5V, the scope is the very low voltage reading.

    But I found a solution. I mentioned in the original post that trigger actuator, just once, causing 400 + edge detections/counts when viewing in MAX. It is a large number of charges in such a short time. So I programmed in a digital filter using a min pulse width. ".". 00256. Eliminating the 400 + short bursts of any signal. I used the example of filtering VI in this knowledge base article:

    http://digital.NI.com/public.nsf/3efedde4322fef19862567740067f3cc/9ece7dbe7df338bd86256f8600734a41?O...

    For those who have similar problems, there is no physical change, just incorperate of wiring of the filter.

  • Start trigger M Series C++

    Hi, I seem to have discovered a bug in my C++ when I tried to delete some maps:

    I usually synchronize each task to a task and THE task is linked to the NISYNC_VAL_PXITRIG0 using DAQmxCfgDigEdgeStartTrig

    Now it worked well as my main task was a S series, but when I was doing my Masters M and acquiring signals series, tasks they never start.

    And Yes, I did some tests on the S series (bind it to a NISYNC_VAL_PXITRIG1 watch it freeze... to make sure that it was indeed listening to the trigger signal)

    Also, if I remove the beginning of NISYNC_VAL_PXITRIG0 relaxation, it works like a charm...

    Finally, each task is linked to the task of master by his "/ AI/StartTrigger ' and it works very well...

    NISYNC_VAL_PXITRIG0 so only is a question... is it because some locations receive the signal sent by the PXI_Trigger or something?
    Should I use the STAR version instead? (With the help of a calendar in slot 2 card)

  • Producer consumer Start Trigger

    Short explanation: I use a party apparatus 3rd signal a TTL to use as my trigger early in my VI. My cDAQ and modules seem to have the ability to send a trigger start regardless, but I could not track down the how to do this in a system of producer/consumer.  I have an idea at the bottom of the long explanation.

    Long explanation:

    I am running a test system that monitors the pressure wave by an inflammation of the hydrogen/oxygen. The components are a cDAQ-9188 with modules 9222 (x 3 HAVE broadband), 9481 (x 2 relays), 9402 (x 1 i/o Module), 9221 ('Low' speed HERE).

    Based on the recommendations contained in this forum, I placed my DAQ in a producer/consumer architecture.

    At this point the system works for the most part, I still have some more things to add for all the information I want to collect. However, it records at high speed and the 9221 and the 9222 modules are synchronized. He collected reliable data to date successfully.

    When the system boots it will follow, but not save. I need to fill the structure tested with gas at a specific concentration before I switch on/registration. When I press the record button I have a TTL of the 9402 signal to my high-speed camera and I close a relay on a 9481 who engages in an ignition system. Ignition system takes a variable amount of time to load and shoot so I have a timer that leaves the TTL and the active relay for half a second.

    My problem and it is a small, comes up with the system monitoring and synchronization. In order to get the system to synchronize properly, I had to generate an external impulse in PFI0 to use as a trigger. I tried to assign the different clocks available as a trigger of the beginning, but I found myself with unsynchronized data.

    Is there a way to generate a pulse on my 9402 to use as a trigger? It feels stupid for me to use an external device, when I have something that can generate the signal that I need.

    Thinking about this post, I have solved my problem, at least in my head. I think I can move the output TTL VI (that I'll eventually change to DAQmx) in the loop of producer and move my statements true or false for the consumer in the form of a 1 d array loop in my queue to start recording. Probably more than that, but I can only learn by experimentation on the right?

    Thoughts? Recommendations?

    VI attached.

    You cannot generate a pulse with the 9402 himself. The pulse would be actually generated by the 9188. You must create a task of meter output to generate a pulse train. Try the attached example as a starting point to experiment with the meter.

    This Vi is for LabVIEW 2013, if you have an older version let me know and I'll try to convert.
