Input & output simultaneously: resource reserved?

I am acquiring analog data, then trying to output a DC voltage of 5V at a specific time. I get the error that the resource is reserved. I'm guessing the DAC can't be used to input and output on the same device at the same time?
Below is a picture of my program. Everything is in a while loop. Once I hit two peaks detected (provided they're time apart is greater than 250ms but less than 5000ms), the output voltage should fire. However, I get the error.
Any tips on what I'm missing? Thanks a lot.

Hi Ktread
Thank you for using our discussion forums.
It is possible to configure one input task and one output task at the same time, as they each have independent timing.  You are getting the described error because you are using both the new DAQmx driver for your acquisition, and the Traditional DAQ driver for you generation on the same device.  This is not possible.  The easiest way to solve this issue is to replace the generation VI that you are using to update the output with either a DAQ assistant such as the one you are using for your acquisition, or replace it with DAQmx code.  There are helpful example programs that you can use in our example finder.  They can be found at Help>>Find examples, and then from the Example Finder browse to Hardware Input and  Output>>DAQmx, and choose the desired example.

  • Using Counters as Input & Output simultaneously

    Hello All,
    I am using PCI 6221 (68 pin), I am using one of the counters as inputting pulses to a servo, can I use the other counter "Counter 2" for counting thoses pulses which I am generating from "Counter 1", also I want to make it synchronized.
    As soon as I generate pulses my reading counter should start, anyone help me with some example.
    Using LV 8.0
    Thanks

    Hello James,
    If you are outputting a continuous pulse train then you should be able to use the second counter to read them back in.  If you're doing a finite generation to the servo motor then that task is actually using both counters (one counter gates the other:  How Many Counters Does Each Type of Counter Input or Output Task Take?).  Assuming that you do have an available counter then you can run any of the single counter input tasks listed in the above KnowledgeBase article.  There are a number of counter input task examples in the LabVIEW Example Finder that you can access by opening LabVIEW and going to Help» Find Examples...  Then navigate to Hardware Input and Output» DAQmx» Counter Measurements.  From there you'll need to find the example for whatever type of measurement you want to do.
    Synchronization is a different issue.  In general synchronization requires that two tasks start at the same time and share a timebase.  In this case, you can start the counter input task first since it will be waiting on the counter output to start measurements.  Then, if you do a buffered counter input measurement (see example finder--you'll need to set up an implicit sample clock), you'll get exactly one counter input measurement for each period of the counter output.  This happens because for frequency/period/pulse width the counter latches one value on each rising or falling edge so the measurements are automatically synced.
    I hope this helps, and have a great day!

    Whew, generally those errors would indicate a serious Hard Drive problem, but possibly RAM or Logic Board... any other drives connected?

  • External Hard Drive Input/Output error

    I recently started having problems with an external hard drive setup that I did not have problems with prior to upgrading to 10.5.5 and trying to setup the drive to be compatible with Time Machine.
    The hard drive enclosure that I have has 2 bays for two SATA drives. I have used this enclosure without any problems until I tried to get 1 drive to act as the backup drive for Time Machine and the other to be storage. I formatted them using Drive Genius. I used the option for GUILD or GUIL which it said was the better format for using with Time Machine.
    The first problem I ran into since upgrading and reformatting the drives is I got an "input/output" error the first couple times I connected the drive via USB to my Mac. I could still use the drives but I got weird errors every once in a while like "input/output error" or "device was not ejected properly" even though the device had not been unplugged.
    Now the drives will not mount using OS 10.5.5. The drives show up when I open Disk Utility, but I cannot get them to mount. I have ran Disk Utility First Aid, and it says the drives are fine. There is one error that shows up when I run the "Repair Disk" feature. It reads "Invalid content in Journal". But Disk Utility also says "The volume was repaired successfully".
    I have seen some posts when I do a search in google about this issue and it seems this is a known issue. Every suggestion I see says to insert your Tiger DVD and reformat the drive using that and the problem will be solved. The only problem with that is I have a lot of important files on the drive that I cannot lose. I had the files backed up until I moved them to the new drive a while back. Now I do not have a backup because I was in the process of switching to bigger drives and erased the old drives after doing so because everything was working fine.
    I am hoping someone out there may have some suggestions (other than erasing the drive) to get my dives to mount so I can transfer the data off to another drive and reformat after.
    Thanks,
    Paul Rugg

    Thanks for the suggestion.
    Do you think that would work better than Drive Genius? I bought Drive Genius 2 and it does not even see the drives when they are plugged in unlike Disc Utility which can see the drives but cannot mount either one.
    Maybe this following post I made to a different questions may help. The data on the drive is other buying another program for if it will work. I think my next step may be to go over to a friends place and try to mount the drives on his computer and transfer stuff off if they connect.
    text below posted to other question relating to external hard drive problem.
    I have recently had the same mounting issue with my new external hard drive. I just purchased a new 750Gb Western Digital Sata drive and got everything transfered over to it. Immediately, I got an error saying that the drive had been ejected incorrectly even though it was still plugged in. I was a little curious. I restarted the computer (hard drive still plugged in via USB 2.0) and the drive showed up just fine. I plugged another 250Gb drive into the same case (2 bays) and the 250GB drive showed up just fine.
    Well, I then noticed there was an OS upgrade available when I ran Software update so i ran it and when I rebooted the drives were gone. I can see the drives in Disc Utility, but they will not mount. Drive Genius cannot see either disc. Disc Utility says I need to repair the drives, but when I do it says they are fixed but they don not mount.
    The problem really seems to be related to mounting USB external drives. I got ahold of 2 seperate external firewire hard drives and one shows up just fine while the other has the same problem (both work on other systems. I would try wiping the drives and reformatting but ALL MY stuff is on them and not everything has been backed up. Yuck! I have not tried connecting my hard drive to another Mac yet.
    The drives being used are #1 Maxtor Maxline Plus II 250GB SATA/150 HDD 1.5b/s 7Y250m00654ra
    and #2 Western Digital WD7500AACS WD Caviar GP Green Power drive.
    I have another post similar to this and I have not received any feedback, but I have been doing my own searching and have found similar posts on the net.
    Anybody have any clue what might be going on here? It really seems to be related to my upgrade.

  • I am in mavericks disk utility recovery mode as my mac book will not boot up & stays only on the grey apple screen. When I verify the disk I get open error5 :input /output error on Syst stuck on 1 minute pouring out over 50 error messages & still counting

    I am in Mavericks disk utility recovery mode as my mac book pro will not boot up & stays on the Apple grey screen . When I verify disk permissions I get
    Open error 5:"input/ output error" on syst with over 50 of this messages & still counting . Disk Utility says 1 minute
    But this has been going on for over 10 mins .
    I can not verify disk or repair disk .
    I have tried to reinstall mavericks operating system but it says my hard drive is locked which is very strange .
    Does anyone know what is going on here ?
    My system looks like it has been totally corrupted . Thanks Andrew

    Could be. The "lock" isn't actually looking for a password.
    WARNING: This will completely erase the ENTIRE hard drive.
    What you would need to do is boot to recovery > disk utility > select the MAIN drive on the left side > partition > change partition layout from CURRENT to 1 PARTITION > ensure on the right side it says Format : Mac OSX Extended (Journaled) then push APPLY.
    Then if it will allow us, close the windows until you see the 4 options popup again and select "Reinstall Mac OS X" select the Mac HD and you should be good to go!

  • I am trying to run my electric guitar in garageband 11 but there is no options to modify the inputs/outputs to built

    There is no option to modify the sound input/output to built-in input or built-in output.  I'm guessing the electric guitar is not being registered.  I am using a 1/8" mono -1/4" mono cable to go directly from the output jack on my electric to the headphone jack on a macbook pro.  How can I get this to work?

    When you use an external device for input, GB often automatically selects that same device for output. It's an ease-of-use feature for most external devices. If your device doesn't give you the option to output to speakers/headphones, you don't want GB to do that.
    Within GB, go to GB>Preferences, Select the Audio/Midi tab. In the Drop-down under output, choose "Built-in Output" and connect your external speakers/headphones to the Mac's headphone port (Alternately, you could use system preferences to direct your Mac's audio-output to your speakers and select "System Setting" in GB Prefs. The Mac's own speakers aren't going to be nearly as much fun as running it to your big speakers/headphones).
    Hope that makes sense...

  • Disc image input/output error

    When burning a disc image using disc utility, I get the ever so popular input/output error message. I cannot find anywhere on these posts a solution to this problem. It is not dirty discs, etc. It happens when I try to copy dvd's... which are not licensed, etc.

    Could be so many things, Input/Output errors are generally loosing contact with a device for a variety of reasons, do you get any error # with that?
    Open Console in Utilities & watch for more info whn you try to burn, or open the Disk Utility Log if there.

  • "input/output error' when making disc image from DVD

    I've had problems installing Logic, and a Pro Apps Genius at Applecare suggested I try making an image of the problematic DVD (Audio Content 1) and then trying an install that way.
    While I can make an image of the Install disc to my desktop fine, the Audio Content 1 disc reports an "input/output error".
    This means I'm unable to copy the disc and then successfully install my Logic Studio.
    Any ideas?

    Thanks for your answer.
    Yes, I thought that might be the case - but I'd taken my Mac and Logic disks to a Genius bar, and the 'Genius' had said he'd fixed the issue. I just wish he'd explained what he did and why he didn't replace the faulty disk(s)!
    But is there any way around having the claim a disk, now I'm living abroad and my 'warrantee' has run out? It's going to be a pain in the fundament trying to claim a replacement set.

  • How to set input/output "use" attribute in the WSDL file of BPEL process?

    Hello,
    I have a BPEL process that I want to deploy it as an RPC web service. I want to access it from a Java module (via an automatic generated Java stub from the WSDL file exposed by the BPEL process).
    I wrote manually the corresponding WSDL file for my BPEL process, where I stipulated for the operations exposed by my process ( in <soap:binding> tag) the value of the attribute "style" to "rpc". Also, for each <input> and <output> of the operations (inside the <operation> tag), I set manually the attributes "use" to the values "encoded". Something like this:
    <operation name="getCustomers">
    <soap:operation style="rpc" soapAction="getCustomers"/>
    <input>
    <soap:body use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="Trial"/>
    </input>
    <output>
    <soap:body use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="Trial"/>
    </output>
    </operation>
    The issue is that, when the BPEL process is built and deployed, the WSDL file generated automatically by BPEL (based on the one manually writen) set the values of the "use" attributes to "literal". This is what is generated:
    <operation name="getCustomers">
    <soap:operation style="rpc" soapAction="getCustomers" />
    <input>
    <soap:body use="literal" namespace="http://acm.org/samples" />
    </input>
    <output>
    <soap:body use="literal" namespace="http://acm.org/samples" />
    </output>
    </operation>
    Is there any chance to keep the original values (written by hand) for the "use attributes?
    Many thanks in advance!
    Regards,
    Marinel

    I am not sure I understand your question. If you want all your BPEL service to be rpc still by default, you can change the templates: C:\eclipse\plugins\bpelz_0.9.XXX\templates.
    The BPEL PM engine support both style of invocation.
    I hope this helps. -Edwin

  • Input/output error when copying a DVD

    I created A DVD some time ago using Roxio.  It plays in DVD Player on my Mac Pro, but I can't create a .dmg using Disk Utility.  I always get "Input/Output error".  I got the same result on my wife's newer Apple. I tried to Restore it but can't, and Verification shows no problems that I can see.  I am able to copy DVDs created on Final Cut Express just fine.  Any suggestions to help me create copies of an old DVD I love?

    I just figured out how to get around the problem.  Download Burn and use it to burn the VIDEO_TS file to a new disk.  It must be something that Apple adds to make it hard to copy DVDs made from non-Apple software.

  • External Hard Drive not Readable & Input/Output Error?

    I was using my OWC 300gb external hard drive for a while and it's worked great. I had a bunch of files on it, but I recently transferred everything to another external HD I have, which worked fine, so I could erase this 300gb one. I can't remember what happened, but somehow my Macbook doesn't recognize this hard drive. I think erased everything and then unplugged it without ejecting it first. Anyways, nothing is on the the drive anymore and I get this error message:
    "The disk you inserted was not readable by your computer"
    This pops up when I restart my Macbook. When I try to use Disk Utility, it greys everything out on the partition and Disk Repair tabs. On the 'Erase' tab, it will allow me to select Erase, but then gives me the error:
    "Input/Output error"
    Does anyone know how to get my Macbook to see my drive (so I can start to partition it)? For some reason only Disk Utility acknowledges it's there, Finder won't.
    Anyone have any tips of what it is or what I can try? I did try to use my OS discs booting up holding C, but that doesn't work either.

    Hi there. Everyone is saying on these forums that the hard drive is failing...suck. I went and bought a new when I got input/output error and found that the new one showed the same input output error, making it impossible to partition the disk. Then the guy in the apple service center told me the new one was bad too, after having seen the code that came up related to my new scorpio 250 GB drive. Instead of sending it back, I took it out and installed the old one..however this time with a slihtly more of pressure on the tape holding down the hard drive cable between the hard drive and the circuit board. Amazingly, this time it didn't even show any hard drive at all! Then I understood what was wrong. It was exactly what was indicated an "input/output errror"! ..the cable was broken. I bought a new cable, well the Powerbookmedic sold it as new but it was an old working one that arrived. Immediately, after change of cable the old hard drive and now also the new 250 GB works perfectly! I remember that some interesting symptoms prior to all hard drive problems appeared, such as not being able to start up properly, strange blue screens, flipping question marks etc. I remember that shaking the comp occasionally worked to get it going. No wonder, shaking occasionally made it work and i believe the damaged cable maybe changed position and started conducting. The cable is very sensitive and probably should not be taped down so hard as the first service center guy at apple had done with mine when he fixed it the comp a few years ago. Polymers/plastics bent heavily become fragile/brittle with time and are specially sensitive under pressure/bent. Note that my old damaged cable still conducted and showed the hard drives but didn't work fully. I hope this will help someone, it took me 2 month to figure out..
