DAQ 6009 release latches to value even after VI stops running.

Hi all.

I had this particular problem.

I use a simple VI to generate zero to five volts on AO0 6009 DAQ.

When the VI is running, I can change continuously the voltage with a slider, and it's good.

But when I press the button 'STOP' on the VI (while the loop continues), the voltmeter connected to the output of the DAQ 5 volts shows (if 5 volts was the last position of the cursor).

So if the VI has stopped, data acquisition always shows the last value.

How to stop the VI DAQ understand that he must go back to zero?

I have attached 2 types of codes below gives the same results.

Thank you very much.

It is not at all strange. It is planned. To set the output to 0, simply do another writing DAQmx before deleting the task.

  • TimesTen does not release the shared memory even after DB destroy

    Hello

    After that TimesTen DB is destroyed, the shared memory allocated to the DB is not to be released by the system.
    We use TimesTen release 11.2.1.7.0 (64-bit, Linux/x86_64)

    We need to restart the system for shared memory usage (outdated) by clearing TimesTen.

    Please let me know what is the problem here.

    Concerning
    Pratheej

    Hi Pratheej,

    How are actually destroy you TimesTen? are you using ttDestroy? It seems that you may force a shutdown of the master demon TT? In which case the current connections will not aware the master demon went so far that they try then access TT until they can keep the memory shared memory segment.

    Take a look at ttStatus to see which links are open. Unplug them all by default that TT will come out then memory, you can use ttDestroy.

  • Firefox 25.01 - blocker blocks pop-ups even after you stop it

    I use a greasemonkey userscript which, on the use of shortcuts keyboard, triggers the search for all links on a Web page containing a certain keyword and them opens automatically in new tabs. The script seems to work fine except when the open links are too many (more than 5 for example), then firefox displays popup blocker bar and prevents the opening of all the other links. I tried to add the site to list exceptions and even disable the blocker, but he keeps blocking the tabs even though the exceptions list shows the added site. Is there a work around for this problem? Any suggestions? Help, please.

    Thanks in advance.

    It is possible that you are having this pop up maximum (the default is 20).

  • Why substitution strings are now old value in application translated even after seed/publish?

    Hello

    Recently, I noticed a small, but from the perspective of our customer "big" issue. We defined in our application, some chains of substitution to keep more detailed information about the version of the application. Later, they are used in page templates to display information to end users. Recently I had to update the value of one of the chains of substitution. The change is immediately visible in the main application. Unfortunately, it is not the case for the translated application. For some reason the old value is retained. Even after doing the "seed"-> "Apply translation file"-> "publish." It is keeping the old value. I tried to use the "Translatable" checkbox in the model. In the translation file, is to show correctly the substitution in the 'source' and the tags string 'target', but still he is resolved to the old value.

    We use the APEX 4.2.2.00.11 running on 11g.

    Waiting for suggestions that maybe it's me forget somewhere extra time "checkbox. Thank you in advance.

    Greetings,

    kempiak

    It was my mistake. Value of the substitution string is included in the translation file. I changed it it and it works perfectly.

    No, it's the same code, just a question of if you are looking for passing false to true (lock when you press on), or true to false (by releasing latch).  The "PtByPt of through Boolean" VI (Signal Processing-> Point by Point-> other PtByPt functions) can detect one and is probably the easiest solution, you can just wire the digital input it and select the appropriate transition.

    You can use the SearchReset extension to reset preferences to default values.

    Note that the SearchReset extension runs only once and then uninstalls automatically, so it will not appear on the page "> Firefox Add-ons" (topic: addons).

    Hello

    I installed an Alfred Workflow (see code below) that will mark all my mails as read. After you run it for a minute, the mail has crashed and I had to forcequit. However, now, when you open the Mail it crashes instantly, even after restart and repair the permissions. I also used the Ctrl + C and CTRL-Z commands in the Terminal to leave the alfred_script, but nothing helped. I'm running out of ideas here, so I hope you could help me either reinstall the mail.app. I could always just switch to a different mail application, but it's kind of a last resort.

    Code:

    Tell application "Mail".

    Define allAccounts on each account name

    Repeat with currAccount in allAccounts

    the unreadMboxes value (each mailbox to the account currAccount the unread number is not 0)

    Repeat with currMbox in unreadMboxes

    (read status of each message to currMbox including the playback State is set to false) true value

    end repeat

    end repeat

    tell the end

    Any input would be greatly appreciated. Can post the report of crash on demand.

    Not sure that Alfred's, but it's just an Applescript script and it would not cause Mail to be planted.

    However, when running through all the messages, it is possible Mail database has been corrupted and it crashes because of this.

    I'll probably get anything out of the accident report, but others might.

    My first instinct would be to rebuild the mailbox. Because you can't do that with him crashing, you can simply delete the databases and it will rebuild them.

    Navigate to this folder:

    ~/Library/Mail/v3/MailData/

    You can either manually through the files, or copy the full path and paste it into go the folder in the menu go to the Finder.

    Remove the envelope Index files. Open Mail and see if it works well.

    If your library does not appear in your folder, hold down the Option key and select library in the menu go to in the Finder.

  • Run DAQ 6009 in different screws at the same time

    Hi, I need to use the DAQ 6009 case in two or more different subVIs to you same time.

    I have a main VI running two subVIs in parallel. The two sub - VI reads two ways.

    The problem is when a Subvi 'open' or inizializes the DAQ before others and he just read two channels.

    Can I use the DAQ in subVIs in you same time?

    Hi rvenge,

    You cannot share a single resource (as your channels of USB6009 AI) in several places.

    Solution:

    Create a VI that manages all channels of HAVE and stores the current values in a location accessible by the other screws (notifier, globals, FGV...). All the other screws to access the data at this location...

    Hello

    The process of database have a file handle for the data file - this remains even when the file is deleted (it disappears from the normal file system navigation)

    You can see if you have lsof installed

    just try

    lsof | grep datafile_name

    Once the database is restarted and the released file handle so you will not be able to do this any more - and in fact you will get errors when it can't find the file.

  • How to make a slide to wait until the user has answered a question correctly, even after activation of a smartshape?

    Background:

    I created a questionnaire in which the user must answer each question correctly before to proceed to the next slide. That's what I did:


    • Set preferences Settings > required > respond to everything - the user must answer each question to continue
    • Set the number of attempts at the level of the question to infinity
    • Made the Next invisible button and disabled the PlayBar

    In this way, the user can proceed to the next slide in the issue with the submission process - and, since attempts are endless, this means that after having answered the question correctly.

    Current objective:

    I want the user to be able to click on a prompt for a hint. To configure this, I did the following:

    • Created a smartshape titled 'click_for_hint' to display the text that says: "click here for a tip.
    • Created a smartshape labelled 'hint' text display
    • Show "hint" success value "click_for_hint".

    Now, when the user clicks on the text that says: "Click here for a hint," the suspicion appears. So it works - great! However, once the indicator is activated, I would like to for the user to continue endless attempts until respondent correctly to the question... and then only after answering correctly, proceed to the next slide.

    The problem:

    If the user has submitted one or more wrong answers, and then activates the indicator, the slide just waiting until the user has answered the question correctly. Instead, it will be set in playing, proceeding to the next slide. I tried the smartshape 'hint' to take a break on the success of adjustment, but it does not work.

    Is there a way to make the slide to wait until the answer to the question correctly before moving on to the next slide, even after the indicator has been activated?

    Are you aware that your required parameter can cause problems, the blocking of the user? It is also completely useless because you have unlimited attempts at the level of the issue and hid the next button (hope, you don't need review, otherwise, I would recommend not to hide this button but slide it under the Clear key: the Question slides in Captivate - Captivate blog)

    The index problem is related to the fact that a simple gesture going out of reading. I would like to see the timeline of the slide, to compare the points of suspension form and the question slide button. And maybe this blog can also clarify difference between simple/advanced: Why choose Standard Simple action?-Captivate blog

    Regarding the buttons on question slides form: buttons on slides of Question/Score of Captivate 6?-Captivate blog
