• VISA: (Hex 0xBFFF0015) timeout expired before the operation is complete.

  Hello

  We use LabView to control a sequencer of high-voltage (HVS448LC 3000 D) LabSmith using LabView drivers from the manufacturer, power supply. Everything works well in our program (attached) until we try to use another program on the computer at the same time. For example, if we try to open a window for our camera, or even a folder in Windows, the program gives the following error:

  1073807339 error has occurred in the CITATION read in FromHVS448.vi-> CommandHVS448.vi-> RegulateVoltage.vi-> Gated timed injections version 06.the vi

  Possible reasons:

  VISA: (Hex 0xBFFF0015) timeout expired before the operation is complete.

  We would like to be able to control the camera software and the power of LabView by using the same computer, but we do not know what could cause this problem. We would appreciate any suggestions! Thank you!

  You should really put a lot of orders of pre-instrumentation in parallel.  Force an execution order by using the wire of the error.  Serialize all commands to the instrument.  You may have an order interfere with one another.

• How to pass the parameters or values film double hollow?

  Hello

  I create a game in Flash 8 with 2 AS and I have some questions to ask.

  First of all, I'm stuck for 2 days to create a tower Laser beam to the target.

  I searched the internet for solutions but I can't really find one, so I'll try display of questions myself...

  First I tried to create, and the effectHolder in which each laser beam has been created, because it seems I can create only one line in each movieClip...

  _root.duplicateMovie(effectHolder_mc , "effectHolder_" + this, _root.getNextHighestDepth());
  v = a = _root["effectHolder_" + this];
  ray.onEnterFrame = function() 
  {
  v.clear();
  v.lineStyle(1,0xFF0000,100);
  v.moveTo(this._x, this._y);
  v.lineTo(creep._x , creep._y);
  v.text = "True"
  }

  It's triggered eveytime, she was a target.

  With each turn that triggered a laser that I created, it became more than offset, so I tried selfdestructing after some time.

  this._alpha -= 10;
  if (this._alpha <= 0)
  {
       this.removeMovieClip();
  }

  But he did not actually work, so I tried another solution. I tried to give each MovieClip ("Laser"), duplicate code that creates the laser beam.

  onClipEvent(load)
  {
       this.fx = from._x;
       this.fy = from._y;
       this.tx = to._x;
       this.ty = to._y;
  }
  onClipEvent(enterframe)
  {
       _root.dmg.text = "From: " + fx + "," + fy + " To: " + tx + "," + ty; //I used this on a textbox to see if parameters are transmited. But they were all 'undefined'
          this.clear();
       this.lineStyle(1,0xFF0000,100);
       this.moveTo(from._x, from._y);
       this.lineTo(to._x , to._y);
  
       this._alpha -= 4; 
       if (this._alpha <= 0)
       {
            this.removeMovieClip();
       }
                                
  }

  The problem is that I did not know how to pass the coordinates of the tower and the target to the MovieClip so that it knows where to create the line.

  X++;
  duplicateMovieClip(_root.Laser, "Laser" + X, X,{from._x,from._y,to._x,to._y});          
  g = _root[_root.Laser + X];
  g.fx = from._x;
  g.fy = from._y;
  g.tx = to._x;
  g.ty = to._y;

  Please leave suggestions on how to send the parameters or values for the created clip, or an idea of the creation of this line ("beam") for each tower, without so much trolling.

  Thank you

• VISA: (Hex 0xBFFF0015) Timeout management

  Hi all

  I'm trying to commuincate with a patented device.  In full operation, it is supposed to send keepalive type

  data periodically, the first thing to do is so empty the receive buffer.

  My program is, (attached):

  1. set baud rate to 15200
  2. open communication of VISA.
  3. flush the receive buffer.
  4 write \r\n
  5. wait 100ms
  6. read the bytes to the value of the port
  7. read messages until the number of return is zero.

  The number of bytes to the serial port is 360

  The length of the message table is the following:

  Message 0 item has a string length of 87
  Message 1 item has a string length of 90
  Message 2 has a string length of 90 item
  Message 3 item has a string length of 90
  Message 4 has a string length of 3 item
  Message 5 has a string length of 0 item

  Concatenated string length: 360

  The element error 0a error: no
  The element error 1 error: no
  The element 2A error error: no
  Item 3A error error: no
  The element 4A error error:-1073807339
  The element error 5A error:-1073807339

  I can easily rub on the mistakes, but I was wondering if there is a method that does not generate an error?

  Also, why not make one answer rather than separate 5 responses, which results in an error?

  I mean, I love not waiting, is it better to interview a number of bytes > 0 or x number of Foundation that does not change.

  Is there a method that recommend NOR for this simple query series?

  TIA,
  Sean

  Some VISA basics.

  You have the stop activated with the VISA character set up the Serial Port. Then use the VISA to the Serial Port bytes. Using both is not recommended. VISA playback will end automatically when the stop character is detected. If you have a character of endpoint, you can place some high number for the number of bytes to read. If you have no character endpoint, disable it.

  You do not send a return trolley/line with the \r\n. You send each character separately. In order to send '-' codes, you must enable them. Simply right click on the control of the chain and select '-' code display.

  The warning is expected and normal, whenever playback VISA does not detect a termination character.

  Placing the bytes VISA to the Serial Port outside the loop is just incorrect and using a while loop with the VISA Read is just making it worse. You are guaranteeing a mistake.

• DELL INSPIRON 2320 - Natural Wireless Laser Keyboard 7000 - default value is | Caps lock | WE (turned on) in all fields of password

  Hi y ' All

  DELL INSPIRON 2320 - Natural Wireless Laser Keyboard 7000 - default is Caps Lock ON (active) only when the cursor is in a field of password.

  The game of keyboard mouse 7000 is great.

  However, when the cursor is in any field/bos where a password must came me in, CapLock default value (setting) is ON or activated.

  • This only happens only in a field/area requiring a password to enter... but it happens each unique time, any application or what connection Web site password field I can be located anywhere on the Internet.
  • Again, this is only a problem when the cursor is in a password field.
  • This (setting) can be reversed that, when the cursor is in an area of password, default (setting) will be | Caps Lock |  STOP =?

  In the BIOS settings, I only find a selection of NumLock setting.  In Centre of keyboard and Microsoft mouse, the only setting that I can locate offers the choice to enable or disable the use of the Caps Lock key... entirely.  So, when turned on, the default value is lock shift = WE only in a password box.  Know, I is not no accidentally redundant; I repeat this case specific to the question in order to stress that this is the only time only this question.

  Like most people, I have to enter the password often. This problem occurs if the "remember me" or "keep me logged in" is selected.

  It's much more irritating.

  Thank you for your considerations and possible solutions, if any.

  Hello

  To turn off the caps from the BIOS lock, you will need to contact the manufacturer of the BIOS.

  Note: Update of the BIOS can be a complicated process, and if an error occurs, your computer could be rendered unusable. Be sure to observe the instructions of the manufacturer.

• How to pass parameters/field values from one screen to another screen in blackberry

  Hi all

  I have two screens in my Application UI that is, login screen and continue the screen.

  Login screen has some fields of seizure as a user name and password and default language (French or English) for the application (Group of radio buttons).

  There is a button for the next who directs the user to another screen.

  This second screen has an input field. This input field is mandatory. The user can only go further if it is entered in this field of entry with valid values (i.e. numbers only).

  This screen has continue button so that the user can go further is on the next screen after you have entered a valid value in the field.

  Now, when the user clicks the continue button on the second screen so I have to validate the credentials of the user, he has provided in the first screen. Also, I need set the locale for the language he has provided to the login screen.

  So, to summarize.

  (1) user enters user name, password and language on the first screen. The user clicks NEXT and goes to the second screen.

  (2) on the second screen, the user enters a name click continuous. ((3) user credentials are validated, defined locale and user is illustrated below third screen).

  So, my question is how do I access username, the password, the language of the first screen in the second screen fieldChanged method?

  fieldChanged second display method will be called when user enter a value class we second screen and clicks continue.

  Please advice

  Thanks in advance...

  Store text values in the fields in your application class, and then pass it as a reference to each form or retrieve your instance of UiApplication and cast to the name of your class.

  public class MyApp extends UiApplication {   public String username;   public String password;   public String language;
  
  }...
  
  // Your first screen
  
  public class MyFirstScreen extends MainScreen {   private MyApp _app;
  
     public MyFirstScreen()   {      _app = (MyApp) UiApplication.getUiApplication();
  
        // Set your fields      // AS AN EXAMPLE, you can use:      // _app.username = field1.getText();      // _app.password = field2.getText();      // _app.language = field3.getText();   }}...
  
  // Your second screen somewhere
  
  public class MySecondScreen extends MainScreen {   private MyApp _app;
  
     public MySecondScreen()   {      _app = (MyApp) UiApplication.getUiApplication();
  
        // Access your fields      // you can use:      // _app.username      // _app.password      // _app.language   }}
  

  Now, this is one of the many ways to do it, but it works in its simplest form.

• VISA Read Timeout error when using stream protocol BUS

  Hello

  I currently use the BUS Flow for a MFC Protocol and I get a time-out error VISA Read:

  Error 1073807339 occurred at VISA read in Send Setpoint.VI-> test.vi

  Possible reasons:

  VISA: (Hex 0xBFFF0015) timeout expired before the operation is complete.

  I extracted the part of the code and it attached to this message. Basically, whenever I hit OK to send a VISA just read set value times out. I tried to use the sub VI who is responsible to send the set value and it was fine (when manually, I copied and pasted the ASCII codes) but when I run the global function it times out.

  Any help is appreciated

  Thank you

  If you have a command string or a constant you enter a \r\n in, you MUST have '-' Codes view turned on in order to enter the actual control characters. If you enable "\" Codes to display and see \\r\\n, then you have used Normal display to enter the characters.

• Behavior of locking/unlocking of VISA

  I'm redrawing the current VISA drivers for several instruments that we use.  Since it is possible that several different screws will want to access the same instrument more or less the same time, I want to block the instrument to ensure that certain operations occur without interruption.

  I found Async Lock VISA and VISA Unlock and decided to use them, because they are built and seem like they should do what I am trying to accomplish.  ('Use this function to obtain an exclusive lock that offers unique access to a device or resource.')  However, when I send two commands for a device and deliberately delay the release after the first, while the second command should wait until the first unlocked... I see the effects of these two commands at the same time.  Turning point performance highlight confirms that the second instance of VISA Lock Async runs successfully before the first lock has been released.  And they are configured for exclusive locks, shared locks not.

  I've attached a screenshot of an example VI that illustrates this behavior.  I do something wrong, or I somehow misinterpreted the fairly direct language in the documentation of NOR?  Do I need to use semaphores and abandon this cleaner solution?

  I think your problem is that you have access to the same resource. Look at the example program called "locking". Here, there are two different resources created.

• Interactive Control VISA & VISA Read timeout expired

  VISA control gurus,

  I am trying to contact my wireless AGILENT N8300A Test set.

  I am able to do the same thing via NI VISA Interactive Control...

  (Attached is the captain)

  But if I tried to do the same thing with a sample program.

  (Also attached below)... program shows a

  VISA: (Hex 0xBFFF0015) timeout expired before the operation is complete.

  I tried to use Async mode and synchronization in the VI... Reading VISA.

  But it always shows error timeout.

  I'm not able to understand what could be the difference, if it works well

  in an interactive control NI VISA, but not in my program

  Any help or pointers would be appreciated...

  Kind regards

  Hello

  very good that you have added the vi.

  You add a CR instead of a line break.

  You can do that in the string by selecting "------" mode for the string constant, you can use any string appearing in your comment as the display string constant.

  Good luck

• Need help to test the VISA interactive Control: Sorensen XBT32 - 3FTP USB connection problem

  Hello

  I use Windows 7. I installed the USB driver provided in this link:http://www.sorensen.com/products/XBT/XBT_Downloads.htm.

  Max is on the ASRL5: COM5 series & parallel in the Device Manager it is listed in the port: COM5

  I don't know how to test using VISA interactive control to ensure that the connection is established.

  Here are the parameters:

  Serial settings:

  Baud rate: 38400,

  Data bits: 8

  Stop bits: 1

  Parity: None

  I use the default settings for the other options such as flow control: none, Timeout = 2000ms etc.

  In the attributes view tab:

  Attribute: is the connected port

  Current value: error VISA: (Hex 0xBFFF001D) the specified attribute is not defined or supported by the referenced resource.

  I don't know if it's important.

  When I write * IDN? \n (bytes to read: 6), I return the Count: 6 bytes

  When I click on "Read Status Byte":, I get the following error:

  Error reading STB operation VISA: (Hex 0xBFFF003A) cannot start the operation because the installer is not valid (because of attributes defined in an inconsistent state).

  If I click on "Query", I get the following error: reading operation error VISA: (Hex 0xBFFF0015) timeout expired before the operation is complete.

  I also tried to create USB raw driver help driver of VISA Assistant. In this case I kept getting timeout errors: read operation error VISA: (Hex 0xBFFF0015) timeout expired before the operation is complete.

  Can you please tell me what I'm doing wrong?

  Thank you.

  Who cares about the number of bytes written? And configure the windows com port is not relevant. What is important is how you set the com port in the VI or max.

• USB RS232 "is connected Port" "invalid property value".

  I'm quite new to this so if all the below is not clear or needs more explanation Let me know and I will try to provide information.

  I'm trying to integrate a device in my LabView program. Of its guides, that I could find on the site OR mentioned most NI MAX goes first and then working them down. My camera is an RS232 port, so I connected via a USB converter, and I know that I'm looking at the right port (COM5) to look at the section "manage devices" on the control panel.

  All series settings are set up properly, I would say (the user manual ishere, with 17 being the party and my setup herepage). I tried to test commands, he gave me on the input/output section, but constantly came up with the error "VISA: (Hex 0xBFFF0015) timeout expired before the operation is complete." Initially, I thought I entered orders incorrectly, I find instructions in the manual that is confused, especially compared to the things other users have posted on orders ('\r' and '\n' instead of what I am told to write, but I agree that mine are not always literal characters).

  But when I went back to "Display attributes" connected "East Port" final attribute has an error with the "invalid property value" and the warning Hex 0xBFFF001Derror. Because of my inexperience with all this, I don't know where to start really trying to solve this problem, or what measures are in place, I need to do to start working properly.

  All advice is appreciated. Thank you

  The property "is connected" is only for devices of NOR so if you have another brand of converter, you would ignore the error.

• Memory leak with RS-485 visa

  I tried to find a slow memory leak in a large application Labview (2012f3). Using perfmon, probes and breakpoints, I could trace the source of the leak of a series VI communication employing a number of nodes VISA. I have attached a slightly simplified version of the VI leaking (serialCommand.vi), as well as a VISA vi initialization and a VI of container to test.

  Did anyone see any problems with the serialCommand VI that could possibly cause memory leak?

  After reading all posts of the forum that I could find on memory leaks and VISA error, I was still unable to stop the leak. SomeofthethingsI'vetriedsofar:

  -J' read VISA Close can cause leaks memory, so I disabled inside the loop (even if he was closing an event, not the port)

  -J' wrote extra carriage at the beginning of the VI returns, before rinsing the pads

  -J' was initially using VISA 5.2; After the upgrade to VISA 5.3, the leak occurred still

  -J' replaced VISA nodes with constant value placeholders, and the leak repaired (not a solution, but the confirmation that it is the location of the leak)

  It may also be worth noting that I don't remember when this leak memory in the previous development when I was watching for leaks, but a few days ago Labview executable generates started fails with the error 1, and the only way to get Labview to successfully build again should fix labview from Add/Remove Programs (Win 7 Ultimate) , so it could be related to a change of version in one of the packages that has been reinstalled.

  Thank you.

  Is there a reason that you use VISA events?  It seems that you expect just a character.  Why not to use playback VISA wait for a byte and use the timeout if the byte is not?

• How to get the Session ID of VISA control

  Hello

  1. I was wondering if it was possible to get the Session ID for serial port via the node of the control of VISA property but I am unable to find it, but if I put the probe on the Session ID string is there (see serial_session_id.png). Someone knows a good work-around?

  2 when I browse through the items property of the VISA control I noticed that the General parameters appear twice. It's confusing and I don't know if this is a bug or not (see instr_property.png)

  I use LV 2012 with NI-VISA 5.2

  Hello

  You can do this by using the Reffnum to the VI session.

  Please find attached an example.

  Best regards
