Error -200288 on multiple analog ins/outs

Hi there,
I have modified the MultiFunction-Sync-In-Out to accept 4 analog ins and 1 analog out but as you can see I always get Error -200288. I have attached the vi along with this message. If this problem is solved, I would like to output a second analog channel with a pulse to mark signal out from the first analog out. Please advise. Cheers, Biswa

Hi there, Thanks for the message. You are right that this is because of the task not getting stopped at every iteration of the while loop. It seems stopping a task at the end of each iteration only holds for software triggered DAQ and not otherwise.  have herewith attached the next version of the code. The query is if I am doing finite sample acq. and generation (the samples are set as fixed for AO and AI) then shouldn't my text file for data saved via AI/AO operation have equal number of points starting at set start time. It certainly doesn't seem to be the case and I reckon this is something to do with the buffer. Your advice on this would be highly appreciated. Cheers, Biswa

  • Synchroniz​ing two counter frequency inputs with multiple analog inputs

    Hello all,
    I'm fairly new to LabVIEW and I'm trying to collec​t data from multiple sources with synchronized tim​ing on the acquisition but I'm having trouble figu​ring it out. My problem is that I've got two count​er frequency inputs, one optical tachometer readin​g one pulse per revolution, and a max machinery fl​ow meter with a k factor of 12000. I can't seem to​ figure out how to sync the timing with my multiple analog inputs. I've be​en attempting to get the tachometer  to sync with ​the analog inputs first by following the example l​inked here. (https://decibel.ni.com/content/docs/DOC-10785) So far each time I run it I either get a timeout e​rror on the DAQmx read or a "Multiple sample clock​ pulses were detected" error (see attached image).  It seems if I slow the sampling rate way down to ​say 10 hz and ensure that the tachometer signal is​ over 800-1000 RPM (13-17 Hz) before starting the VI then the program will run without errors until ​the RPM drops below that threshold then the "Multi​ple sample clock pulses" error occurs.  The code is attached below.
    Does anyone know of a more effective way of syncin​g counter frequency inputs with analog inputs?  I'd like to have a VI that can show 0 RPM (and ev​entually 0 flow as well, but I think I need to fig​ure out the timing of one counter before I add ano​ther as it seems I can't have two counters in the ​same task). Any help on this would be greatly appr​eciated.

    Maybe third times the charm? 
    So I've finally got a good handle on why the VI is having problems at low RPM though I'm somewhat embarassed how long it took me to do that
    Because I have the counter time synced to my Analog input task if it doesn't see at least two pulses between the two clock pulses set by the analog input task I get the -201314 "Multiple sample clock pulses" error. This seems fine at first as it just sets a minimum RPM that I can measure and it's well below the area I'm interested in so no problems there.  I tried a simple error handler that would clear the error when it happend assuming the loop would keep iterating until the RPM went above that minimum at which point I would get a signal again. This is not the case, the read function just continues to spit out the -201314 error even after the RPM is back in the readable range. So then I tried adding two case structures so that when the error occured it would stop the task, clear the error, and then start the task again on the next loop iteration (Code Attached). This also doesn't work as the error shows up again on the stop task and then AGAIN on the start task on the next loop iteration. It seems this error is not actually being cleared and once it happens it stays with the task regardless of what the error cluster is carrying. 
    Anyone have any ideas?  The only solution I can think of is to just clear all tasks and recreate them each loop iteration until the RPM is readable again but that strikes me as a horribly clunky solution.

  • Usb 6009 multiple analog inputs

    I am currently attempting to sample two different analog inputs at different sampling rates using a USB 6009.  I keep getting the 'resource reserved' error and am wondering if this is not possible using this DAQ.  Questions:
    1.  Does creating two analog input channels on the device cause this error?
    2.  Is it possible to sample at different rates on channels created in the same task?  (i am trying to 'slow down' the second analog input to display switch points to a customer)
    3.  Running multiple analog inputs using independent timing would be better achieved by switching to a higher end DAQ?  If so which would you recommend?
    I have attached my vi.  Thank you in advance for your help. 
    I surf therefore I am....

    demo_nolvl.vi ‏27 KB

    The DAQ boards only have 1 timing clock for the analog inputs/outputs.  So you can only have 1 sample rate on a given card.  I would recommend just sampling at the highest of the desired rates in a single task.

  • Analog VIDEO OUT - has this been killed forever?

    So, have we reached the end of the line for ANALOG VIDEO OUT on ALL devices?
    Apparently, there is NO analog video out on iPod Touch 5th Gen, iPad 4th Gen, or iPhone 5th Gen - all devices with the ridiculously small 8-pin connector, which all run iOS6
    Apple's sales site for the $30, 8-pin to 30-pin connector clearly says "Video not supported"
    What?
    So anyone with an expensive car video system, 30-pin composite video link, home AV receiver, etc. is out of luck?
    Is this a sign that Apple has rolled-over to Hollywood in advance of an Apple TV system that only transmits HDCP-style-encrypted digital TV signals?
    That would be bad
    Anyone have the answer to this?  I've read here that people with 4th Gen devices (iPad 3rd Gen) running iOS6 are also being denied video since the update from iOS5 to iOS6 (which some "believe" is a "software" error in the update).
    Is that true as well?
    Apple couldn't possibly be doing this on purpose to their, oh, I don't know, 100 million users of previous devices - could they?
    Someone - please...reassure us there is a fix in the mix for this mess

    Thanks in advance my friend.Probably not a bad thing that this isn't working for you.
    This is a horrible way to return the contents of a table.
    Are you doing this for educational purpose, or ... what is your goal here? If you just want to return a result set to a client you'd want to look in to using a REF CURSOR and not a bunch of arrays combined with horribly procedural (slow) code.

  • Error -200279 with simultaneous analog input (different devices) and digital output.

    Hi guys,
    I am a beginner in Labview and have been dealing with this problem for a couple of weeks now and just can't seem to get it completely right, I have a feeling there are a few small bugs in my code/hardware setup.
    I am running an scxi-1000 chassis with a 1600 module and 1302C along with a 1303 accesory for temperature measurements, this is connected to four thermoucouples. Unfortunately I have a limited number of modules available so I am also using a PCI-6221 DAQ card with an scb-68 breakout box used for a digital output and analog input voltage channel. Attached is my labview program. When I run the code at a 50 Hz sampling rate it runs with no errors but the data file comes out extremely wrong, this is also attached. When I run the code at 100 Hz I get error-200279 after a few loops. I used to have 2 daqmx timing VIs (one for each input), but the same error would eventually happen, I have also tried increasing the buffer size on said timing VI. I am also using an old computer (Pentium IV) could this effect the program?
    I have learned a lot going through forms for similar problems to mine but I just can't get it to for an extended period of time, I have posted my simplest code.
    Thanks in advance,
    Luca

    Ok this makes sense. I have made the suggested modifications but still getting the same error with sampling rates of 100 Hz or higher. Could you check that I have implemented the queue VIs properly (new file attached)? Also when running at 50 Hz in debug mode it does not look like the second while loop (with the dequeue element) comes into play until I hit the stop button, once I hit the stop button I get the following error:
    Error 1 occurred at Dequeue Element in FinalCombined_2.vi
    Possible reason(s):
    LabVIEW: An input parameter is invalid. For example if the input is a path, the path might contain a character not allowed by the OS such as ? or @.
    =========================
    NI-488: Command requires GPIB Controller to be Controller-In-Charge.
    This leads me to believe I have programmed the queue elements incorrectly.
    Thanks for your help, any suggestions are greatly appreciated.

    the call for physical memory
    CALL FUNCTION 'APPL_LOG_WRITE_DB'
    In this process you only need to provide the Itab with error messages.

    Yes, the XP firewall is running. During the Oracle instalation it poped up twice, but I selected 'Unblock'. I can't turn it off because it is running using the domain settings, but I can add exceptions (programs or ports). Port 1521, tnsping or sqlplus are not blocked and there is an option 'Display a notification when Windows Firewall blocks a program' witch is checked.
