Prevention of timeout to trigger

• trigger Auto USB-5132

  I have a few USB - 5132 s that I am incorporating in montages of test which will be controlled by LabView application basically, I need them to run in auto trigger mode, just like a standard of digitization "scope. By that I mean to set a threshold and use trigger dashboard, but in auto mode. In this case the ' scope retriggers continuously, and when there is a real trigger event, the display syncs upward. " So if you have the game to relax in the center of the screen position, edges that meet the trigger criteria align to Center; Otherwise, the signal is displayed without taking into account this kind of alignment.

  The NO-SCOPE Soft Front Panel application can do that, then I know it's possible. But I can't sort out how to make myself in LabView. One thought I had was to pretend: essentially set up to trigger normal edge and in the case of a timeout, then simply use a software to obtain new data and update the display. But I do not know how to set the timeout to trigger.

  Any ideas? Thank you.

  Andy,

  There is a NO-Scope property that you can use to allow automatic release.  The property is called trigger modifier, and it has two possible values: None (normal trigger) or Auto-Trigger.  Also, there is a property that is read-only called automatic activation, which will tell you if an acquisition was triggered automatically or if a real relaxation has been received.

• Software player with equipment trigger events

  Hi all

  I'm trying to synchronize a number of tasks (software and hardware) to a hardware trigger, where my DAQ (PXI-6259) receives a brief pulse TTL of a box no - PXI elsewhere. I want to listen to this impulse, respond by performing a number of tasks (incl. Configuration of another instrument non - PXI to take a reading via a USB connection to the computer and reconfiguring a switching matrix (PXI-2532)) and loops. It seems that the VISA library can expect a VXI trigger via:

  ...PXI_status = viOpenDefaultRM(&PXI_driver);PXI_status = viOpen (PXI_driver, "PXI12::12::INSTR",VI_NULL, VI_NULL, &PXI_DAQ);...PXI_status = viEnableEvent(PXI_DAQ, VI_EVENT_TRIG, VI_QUEUE, VI_NULL);...
  
  while (true) {
  
  PXI_status = viWaitOnEvent(PXI_DAQ, VI_EVENT_TRIG, 30000, &PXI_eventData, &PXI_eventHandle);
  
  // Do stuff here. Break if done.
  
  }
  

  and the hardware interrupt itself can be configured using the DAQmx libraries:

  DAQmxCreateTask("Epoch Trigger Task",&DAQ_EpochTriggerTask);
  DAQmxCreateDIChan(DAQ_EpochTriggerTask,DAQ_EpochTriggerChannel,"",DAQmx_Val_ChanPerLine);   DAQmxDigEdgeStartTrig(DAQ_EpochTriggerTask,DAQ_EpochTriggerChannel,0) // 0 = rising edge
  

  So, my question is how to get the hardware trigger generated since the acquisition of data so that it is detected as a VXI trigger?

  Thanks in advance - CDE

  Comment of final - I had to change the lines I used on port 1 to a line that I used on port 0, and triggering now works as expected. I have all 326±10 µs delay between the trigger amount front and a pulse response on a separate line (port2.line6). Hope it will be useful for anyone who reads this thread then.

  Final code:

  // Configure the dummy task to listen for the trigger
  DAQmxCreateTask("T_di_ETr",&DAQ_Task_EpochTrigger);
  DAQmxCreateDIChan(DAQ_Task_EpochTrigger,DAQ_EpochTriggerChannel,"",DAQmx_Val_ChanPerLine);
  DAQmxCfgChangeDetectionTiming(DAQ_Task_EpochTrigger,DAQ_EpochTriggerChannel,                                                  DAQ_EpochTriggerChannel,DAQmx_Val_FiniteSamps,1);
  

  // Wait for trigger signal
  double timeOut = 10*60; //  10 minute timeout, units of seconds
  time_t start = time(NULL);   
  
  while(abs(difftime(time(NULL),start) <= timeOut))
  {   // individual waiting events have a 10-second timeout (in s).
   DAQ_Task_Err = DAQmxWaitUntilTaskDone(DAQ_Task_EpochTrigger, 10.0);
  
   if ( DAQ_Task_Err >= VI_SUCCESS )
   {
    printf(" Trigger Recieved.\n");
    DAQmxStopTask(DAQ_Task_EpochTrigger);
    break;
   }
   else
   {
    if ( DAQ_Task_Err == -200560 ) // -200560 = TIMEOUT code
    {
     printf(" Waiting for Trigger...\n");
  
     if ( abs(difftime(time(NULL),start) > timeOut) )
     {
      printf(" Trigger Timed Out. Exiting.\n");
      break;
     }
    }
    else
    {
     printf(" ERROR waiting for Trigger.\n");
     break;
    }
   }
  }
  

  Only last issue is management of errors in the final version of the code.

• Configure the keyboard backlight Timeout

  Hello, I want to configure the keyboard backlight Timeout on Dell Latitude E6440. I use pre-installed Linux OS Ubuntu 12.04.2 Dell.

  I found this post http://en.community.dell.com/techcenter/enterprise-client/f/4448/p/19415396/19975858.aspx#19975858 of Warren Byle.

  He wrote how to change the keyboard backlight with tool CCTK lighting level. I downloaded CCTK for Red Hat Linux and looks like it works fine on Ubuntu too. With that - token orders that I am able to change the level of backlight on the keyboard which is good.

  But I still don't know how to change the keyboard backlight Timeout. Backlight is still off after 10 seconds. Is there some special - token for this timeout setting?

  According to other messages, looks like configring timeout to 5 minutes could be possible, as there are Windows applications that could do that (for example Dell System Manager Application checkpoint)

• Sound schemes system works is not on Windows 8 computer laptop after fully updated from Windows 7

  As the title says, I have improved my laptop Win 7 with Windows 8 Pro of Dreamspark (MSDNAA). I also did a clean install of Windows 8 Pro on my PC. Everything goes well on my PC. But on my laptop, the sound system system is cut off, even if the volume of the sound system to 100%. Metro applications notification sounds are silent, too. When I open the sound control panel, al sounds preview worked fine (also good default & custom programs to Windows 7). Also, I check the Windows startup sound 'play' & he play every time I start Windows. All the other audio music, videos, game apps, Internet, YouTube, Flash worked fine, the system of sound patterns are dumb. The audio files are all good, not corrupt, the volume of system sounds even on when I found these files on the array of sounds. But when I actually did things like navigate in File Explorer, connect devices USB, emptying recycled bin, there was simply no sound. I don't know if the problem is with my local Windows 7 account now be upgraded & linked with my Microsoft account, since I've heard of people having the same problem & had to create a new account for. Maybe there's something wrong with the admin permissions that prevent the audio to trigger when the events occur. There is nothing wrong with the audio driver since I've upgraded to the latest Realtek HD 2.70 (support Win 8) on both my laptop & PC, has worked on PC & except for this problem, worked fine with any other audio source on my laptop. Help, please. Thank you!

  PS: My laptop is a screen touch 2 - pt 2010, but still usable with the new startup screen. Just info, no doubt, that it has nothing to do with this problem. Although I found it less intuitive than Win 7 desktop. In Windows 7, you can actually swipe to go back & set out in Explorer, touch 2 fingers to right click (rather than just hold), the touchpad had same suggestion of words like WP7. None of them work in the Office of Windows 8. Improve the Office to be more touch optimized, since now the Metro user interface is fully developed. Just say "." Instead, I'm in love, especially on my PC because it run so fast without a hitch!

  I think I found the solution. There is a DWORD key "Mute" in my HKCU root key. Delete it & it's back to normal. I don't understand why there is this key exists.

• Grant permission to select the function but not executed in a PL/SQL block

  Hello.

  I know that there are only two permissions on procedures/functions - RUN and DEBUG.

  But I want to grant EXECUTE permissions for a user so that the user can Select the function to double or to any other request, but not to run(to prevent the user to trigger the update of LMD - insertion, etc.) inside a BEGIN-END block.

  I know that we can revoke access to tables etc. But that access has to give. The user must be able to perform the DML operation, but just not through a function.

  Can someone please help?

  I know that there are only two permissions on procedures/functions - RUN and DEBUG.

  Fix - so give one or both of those who depend on your use case.

  
  But I want to grant the EXECUTE permission to a user in such a way that the user can select the function using dual or any other query but not execute( to prevent the user from firing DMLs - Insert, update etc) inside any BEGIN-END block.
   
  

  You already know that there is NO "select" privileges for functions. a query such as "select the function of double" RUNS the function. That's all what you can do with the functions is execute them.

  I know that we can revoke access to tables etc. But that access has to be given. The user should be able to do perform DML operation, but just not through a function.
  

  Then revoke execute on the service. Then the user cannot run the service either directly or in the context of a dml statement.

• Prevent the timeline to replay a second time click on the trigger

  Hello. How can I prevent the timeline of a symbol to restart when a second time the button trigger and the timeline has already run. I have a line that grows when I click on the button and I want to keep it as. When I click on the button again the line jumps to its original size.

  Thank you

  Add a variable on the scenario of the symbol.

  var a = 0;

  then in your event click in compositionReady use:

  {sym.$('buttonName').bind ('click', funciton ()}

  {if(A==0)}

  sym.getSymbol('name').play ();

  A = 1;

  } else {}

  sym.getSymbol('name').stop ();

  }

  or you could untie your click event

  {sym.$('buttonName').bind ('click', funciton ()}

  SYM.$('buttonName'). Unbind ('click');

  sym.getSymbol('name').play ();

  }

• prevent dublicate Trigger

  Hello
  I need to create a trigger for the table of appointments that will prevent duplication of the appointment. It sits on two fields, the date and time if both exist already it should give an error.
  I went to create the trigger step by step in the apex
  but I'm lost in the body of the trigger...
  
  Thank you

  Do not write a trigger. You want to check the uniqueness? Then use a unique key constraint on your table with the appropriate columns. When a record is inserted with already existing unique values, oracle will throw an error: ORA-00001: unique constraint (constraint_name) violated

  You could then treat errors using the apex_error package.
  For an example look at blog of Patrick Wolf or Google or search the forums!

• in the APEX by clicking on the link hyper does not trigger session timeout page

  Hi all
  I have a question about the application of APEX session time-out. I created a simple application of the APEX. In the region report SQL section, I have code like this:
  
  SELECT DOC_Name, DOC_URL,
  "" < a href = "" | DOC_URL | "target ="_blank"/" > download < /a > ' pdf_link
  FROM test_table
  where emp_number = 00010001
  
  When the user click on the hyper link, it will show the landing page for the user (for example if DOC_URL = 'http://forums.oracle.com', it displays the oracle forum page in a new browser).
  
  But the problem is that after the user session timeout (I set to 240 seconds through shared components > change the security attributes, I put max the session for example 240 seconds timeout) when I click on this hyperlink, it does not raise my session timeout page and it still shows the page (oracle forum page).
  
  Why in the APEX by clicking on the link hyper does not trigger page session timeout after the user session timeout?
  
  How implememt or fix to trigger the session timeout page after clicking on hyperlinks?
  
  (BTW, our version of the APEX is 3.2)
  
  Thank you!

  Hello

  rather than use your my_stored_procedure you could call a new APEX page where you have a page called P999_PDF_ID. On this new page you would have
  treat a front header PL/SQL with the same code you have in your "my_stored_procedure". The only change would be to add a

  apex_application.g_unrecoverable_error := TRUE;
  

  at the end of your code as well as APEX does not generate a standard page of APEX.

  That's all. If a user clicks on a link, APEX will check the session timeout and if everything is ok, download your PDF file.

• Trigger to prevent the update

  I want to create the trigger that will prevent illegal updates, but for illegal data, I want to insert into another table. In order to avoid the update, I have to make an exception, but it will insert is rollback. I am aware of the autonomous transactions (put I insert a procedure which is autonomous transactions) but it seems to me like dirty way to solve the problem. Y at - it another way to prevent the update that does not throw exception. I am also against the update on the same values. Thank you!

  FilipFry wrote:
  I checked the book, so now I am on the departure, how preventing the update in the after trigger without triggering an exception?

  The only way to prevent a updated row in a trigger would throw an exception.
  You may, of course, update leave unchanged data simply by setting the new value for each column in the old value, i.e.

  CREATE OR REPLACE TRIGGER some_trigger
    BEFORE UPDATE ON some_table
    FOR EACH ROW
  BEGIN
    IF( some_condition )
    THEN
      :new.column1 := :old.column1;
      :new.column2 := :old.column2;
      ...
      :new.columnN := :old.columnN;
    END IF;
  END;
  

  This is far from ideal from the point of view redo generation and from a perspective of maintainability, but it would prevent the change of location data.

  Another trigger approach would be to create a view on the table, create an INSTEAD OF trigger on the view and then publish your updates against the view. The INSTEAD OF trigger can determine to apply changes to the base table or not, whether to discard the changes or if you want to record changes in another table.

• Why Digital Edge in Trigger.vi start to make some sort of timeout?

  Hi I do a manual release on my hardwareboard by inserting a 5 volt source the triggerchannel selected a few seconds after I push the Start button.

  The generation ever begins. But if I put the trigger very equal to the sample clock external works listed in annex vi.

  For example, I use PFI7 as source of outbreak which is also the source of the sample clock.

  Could someone explain to me?

  Sincere greetings,

  Lasse

  We can't simply insert a wire with a 5 V potential to PFI6 for example if PFI6 is used as a trigger for "Start Digital Edge" daqmx - vi. The PIN is floating and inserting just 5V does not guarantee a low aboard high.

  If I use a potentiometer to pull on the low channel first, and then increse the tension, the trigging happens.

• Controls that trigger cases of timeout event structure

  In a structure of the event, we can understand the controls in the event of timeout. But if we do it this way, we do not get event data node associated with the controls. I don't know if it is a good practice and whether there are issues listed. Please comment. Thank you.

  A 'practice', it's what you do. You talk about a limitation (or characteristic). Event data nodes display only those items that are common to all the events of this particular event case, so for example "old/new val" is not available if there is also a timeout that is assigned. If you do not need them, it does not matter whether they are there or not.

  This often isn't a problem because you usually only the new value and you can get that by placing the terminal control inside this event.

  If you need the specific event data node, create an otherwise empty case event dedicated to control and raise the timeout event temporarily affecting the timeout to zero using a shift register. Set the time-out period to zero in the case of timeout events. If the new value is also necessary in the case of a time-out, leave the Terminal inside event newval event data node timeout usage in the case.

• camera to trigger external AVT timeout error

  Hello forum,.

  I have external trigger problems for work to the MAX with my AVT F032BC camera Pike.   I was able to get the camera both in labview and MAX (at 800mbps using firewire 1394b) using software release, but I can't get the switch to work.  Whenever I try random configurations in MAX to trigger mode (mode of 0.1, 15; and each setting relaxing high or low), it just expires when I press grab.

  I have a trendy 12 hirose connector on it, with the trigger (4 pins) and GND (pin 1) connected to a TTL pulse generator (5V high low 0V; a relaxation area who worked with another camera).

  Any ideas why this happens?  In addition, anyone know of documentation for the implementation of an external trigger with camera AVT?

  Thank you!

  Veritas

  p.s. I also tested it with the example of NOR, triggered grab, but it also expires, or will be set on the trigger 'off' option when I start the program execution.

  Without triggering, everything else seems to work very well.

  PIN 7 (I/O ground) and PIN 4 (GPI1) for trigger connections. Tyr, you'll like it
