• Synchronization of AO and output counter, arming and triggering the sequence of events

  Hi all

  I'm trying to synchronize a counter (used as a digital pulse) and analogue of a custom waveform output read from the file on a USB-6211. The goal is to always have these running until I hit 'STOP' and to be able to change the position of the pulse relative to each other. I created a VI by combining and modifying the Cont.Gen.Wfm.Int - Clk.Non - Regen.VI and the Continous.VI Gen dig Pulse Train and I'm now able to produce the two signals to the desired frequency, but I can't seem to get the "Initial period" to work correctly. The values that I come home do not seem to match what is happening LeRiz, and the spacing seems to vary from run to run (within each series is constant). In a previous post, Alfred has suggested:

  "Trigger counter outputs out of the trigger to start AO and adjusting the setting 'Initial period' should give you what you are looking for."  Don't forget to start the tasks of meter in the software before the tasks of the AO (if they are armed and ready to go before the start AO is sent). »

  (link here)

  I tried to use the controls and the propertynodes (perhaps incorrectly), but it doesn't seem to make a difference.

  I think what happens is that my arms and firing sequence is not done correctly. I read on as much information as I could about the outbreak and armament, but I don't know that I understand correctly. Most of the examples I found using an external trigger or perform analog input tasks finished. Does anyone have a suggestion on how to start my two tasks in the proper order? Is something else is wrong here?

  Thank you

  Gabe

  P.S. I have attached the VI and a sample waveform read.

  Hi Gabe,

  This is a cleaned of the VI version that should work (you need not adjust the initial deadline on the right fly?).  Instead of reading a file, I made just a simple square wave of 50% to be used for the test.

  Best regards

• Check the sequence of events

  Hi all.
  
  I need to check the order of a series of events that represents the route of a product. If I receive or deliver the product may occur different events, the problem is that not all events are sequential.
  
  For example:
  
  I f I'm delivering a product, can occur one of the events
  
  1 - load
  2 - order for repair
  3. - output for repair
  4 - the order for rain
  5 - output for rain
  6 - delivery
  
  The events of the 2 and 3 are sequential as 4 and 5, but 2 is not always before 4. Another variant is that events 2 and 3 could happen but not the 4 and 5, and vice versa.
  
  To complete my task, I only have the following tables:
  
  -If a delivery or reception
  CATALOGUE _ROUTE)
  NUMBER OF ID_R
  TYPE VARCHAR2
  );
  
  -All events
  () CATALOG_EVENTS
  _F IDENTIFICATION NUMBER
  TYPE VARCHAR2
  );
  
  -Combination of events and itineraries
  () ROUTE_EVENTS
  NUMBER OF ID_RE
  _R IDENTIFICATION NUMBER
  NUMBER OF ID_E
  Priority NUMBER
  );
  
  The priority field is used only in some cases, such events 2 and 3 or 4 and 5.
  
  -Events
  Events)
  NUMBER OF ID_EV
  DATE EVENT_DATE)
  
  The goal is to ensure that all the events have been entered correctly

  Hello

  Welcome to the forum!

  Whenever you have a problem, please post a small example of data (CREATE TABLE and INSERT statements) and the results desired from these data. You don't have to display a large amount of data. In this case, looks like maybe six channels (some of which are valid, and some of whom illegal combinations of events) would be sufficient.

  This sounds like a job for analytical functions. LEAD and LAG are great to compare the values of consecutive lines of the the same set of data. Other analytical functions, such as the COUNTY, FIRST_VALUE and MIN, sometimes combined with a CASE expression, can find further values.
  Sorry, I don't understand your business rules, so I can't be more specific now. Maybe I could show you exactly if I had a concrete example, including CREATE TABLE and instructions INSERT for all relevant tables and the results desired from these data.

• Correct the sequence of events for the loading of XML

  I have a complex object in Actionscript that I managed test and loading on a local computer. However, when I publish on the web, different network conditions cause the application trying to access the properties of the complex object before the XML file that defines it is finished processing. So I get null reference errors.
  
  I'm trying to understand the correct event system to notify my application I want only to access the properties of my complex once the XML file has been finished read to and populated my complex object properties. Any suggestions on what to do?
  
  I really wish that these forums have a tag formatting code or something so it's horrible, but in general this is what I have:
  
  package {}
  
  import flash.events.Event;
  import flash.events.IEventDispatcher;
  import flash.net.URLLoader;
  import flash.net.URLRequest;
  
  public class {ComplexObject
  private var xmlDoc:XML;
  private var request: URLRequest;
  private var loader: URLLoader;
  
  private var property1:String;
  private var property2:Number;
  etc.
  Supposed getter and setter functions
  }
  public void loadData() {}
  This.Request = new URLRequest ("config.xml");
  This.loader = new URLLoader (this.request);
  this.loader.addEventListener (Event.COMPLETE, xmlLoaded);
  }
  private void xmlloaded(evt:Event) {}
  this.xmlDoc = XML (this.loader.data);
  fill the object with the elements read from XML file
  This.Property1 = xmlDoc.property1
  etc.
  }
  }
  
  I can import and instantiate an object of this class in the main MXML file and call the function loadData fine locally. When there are network issues involved (IE on the web) I want the XML processing to occur independently and complete before doing anything else. What is the correct order of events management? My question may be too complex, but any tips or pointers to resources would be appreciated.

  I see nothing obviously 'wrong' with what you do; the complete event should not be distributed until the data has been loaded. I don't see where you apply the actual load.

  However, I use this technique to load XML data. There are easier ways. I would like to use HTTPService with resultFormat = "e4x". The HTTPService result event will be triggered when completely loaded data. You can do either in MXML or ActionScript.

• In the events of sequence - error?

  I'm doing a sequence of events occur one after the other. I have a background image that I want to fade, blur, and then the blades in a Panel. Flash gives me 2 errors when I test:

  Description: 1119: access to property may be undefined MOTION_CHANGE through a reference with static type flash.events:Event.

  Source: blurTween.addEventListener (TweenEvent.MOTION_CHANGE, onMotionChanged);

  Description: 1119: access to property may be undefined MOTION_FINISH through a reference with static type flash.events:Event.

  Source: blurTween.addEventListener (TweenEvent.MOTION_FINISH, onMotionFinish);

  Thank you.

  import fl.transitions. *.
  Import fl.transitions.Tween
  import fl.transitions.easing. *.
  import flash.filters.BlurFilter
  import fl.transitions.TweenEvent

  var BgTweenAlpha:Tween = new Tween (behindTheBrushBg, "alpha", Strong.easeOut, 0, 1, 1, true);

  BgTweenAlpha.addEventListener (TweenEvent.MOTION_FINISH, onAlphaFinish);

  function onAlphaFinish(TweenEvent:Event):void {}
  var totalBlur:Number = 0;
  var blur: BlurFilter = new BlurFilter (totalBlur, totalBlur, 3);

  behindTheBrushBg.filters = new Array (blur);

  var blurTween = new Tween (blur, "blurX", Strong.easeOut, blur.blurX, 8, 1, true);
  
  blurTween.addEventListener (TweenEvent.MOTION_CHANGE, onMotionChanged);

  function onMotionChanged(TweenEvent:Event):void {}
  blur.blurY = blur.blurX;
  behindTheBrushBg.filters = new Array (blur);
  }

  blurTween.addEventListener (TweenEvent.MOTION_FINISH, onMotionFinish);
  }

  function onMotionFinish(TweenEvent:Event):void {}
  var panelTweenX:Tween = new Tween (behindTheBrushPanel, "x", Strong.easeOut,-460, 0, 1, true);
  }

  A brief glance, you pass a bad event to the event handler:

  function onMotionFinish(TweenEvent:Event):void {}

  It should be:

  function onMotionFinish(event:TweenEvent):void {}

• How to control the structure of the event

  What I'm trying to do, it's when the condtion is true, I want that the structure of the event to excute. But the event structure wil excute not except if he's changed the puch model, any idea how?

  It is more likely that he wants the sequence of events that he has set up to run after the result once changes.  If you change the logic to check the values after each numeric change (2), you will need to learn how to check to make sure that the latest iteration was not true.  Otherwise, it will start the sequence over and over.

  Really, you have to escape completely the structure of the event.  This isn't what you want.  Your code lends itself to a great state machine.

  You'll want to ask you a few things:

  (1) I want my code to run continuously or I just want to check double-digit times? (your code is currently the second)

  (2) I want the user to be able to stop my code once the sequence begins? (it is usually a Yes)

  (3) what I want 6 Road, path 5 or the comparison to happen first?  I want all run at the same time?  Do I need one before the other? (currently, you cannot predict what will happen first).

  You will need to understand the topics are: State of the machines, the flow of data, structures, business, calendar, and race conditions.  Now, you need to get you into trouble.

• Subsequent event not triggered?

  I have a MAIN VI and VI SUB who communicate through control refnum events. sequence of events is as follows.

  (1) void / vi changes a value in its control and this event is handled in the main vi (this works)

  (2) main vi in response to the event changes one of its control and fires an event to the event handler itself that is managed in the handler of sub - VI.

  the first phase is completed. now, the main vi runs a while loop and the sub vi runs in loop a while and main vi triggeres an event each ~ 150ms. that should be handled in the Subvi. This is the part that does not occur. I can see the main vi updated control, but (if generated) event is not handled by the Subvi. I use node-> (signalling) the Value of the property of the control to change the value and the firing of the event. what may be the possible cause?

  hope my question is clear.

  I found the problem.
  the subsequent events were not carried because the loop in which the event handler ran in a loop * once *.
  That is, the initial condition was itself false then the loop only ran once.
  This loop was controlled by ' stop if true '. He had to be 'continue if true'.
  the Boolean variable that controls this loop was real. This should have been my first clue.

  Sorry for the inconvenience

• problem with VI execution to the use of the structure of the event

  I close with this sub - VI, but it reacts as expected. My logic was 1 tables initialized with sequence, then the structure of the event in many different cases. The goal is to read a 2D .cal file 1 2 tables. Cells can be modified manually by typing in the text box, then clicking on the load button. Slider determines with cell in the index. Certain sequences of events work either

  (1) download the cal file

  (2) move the cursor

  Type 3) x input box

  (4) load x value

  Other sequences of events are the VI does not, i.e.

  (1) type x entry box

  (2) load x value

  Can some kind soul tell me the error of my ways?

  First glance only:

  You need to connect the tables 1 d in any event, other that they clear.

• Front Panel does not (exactly 2 even while in flat sequence loop)? LabVIEW BUG?

  Hello world

  I have two while loop with exactly the same code and a user in each loop event structure,

  They both make the same thing which is too run until IMAQ image control (one line) click on a recording.

  I used a flat sequence to manage the order of execution.

  The problem is when I use only one single loop (put another in a diagram to disable) the façade answer perfectly and the program does what it should, but when I activate the two loops stuck in case of timeout...

  I do not understand what is happening that I can't do any activity of façade that would be registered, enclosed is a copy of the VI (you need NIVision run the vi).

  Any idea? Is this a bug or did I do something wrong?

  Thank you very much

  Best regards

  This isn't a bug, but the expected behavior. You cannot sequence structures event like this, they both need to be ready to react. Use a single event structure and a state machine architecture. You have about 4 copies of basically the same code of event management. Try to combine everything in one!

  What happens in your case?

  Answer: The two structures event will begin immediately queues of events, but the second event structure cannot respond to them because it is inaccessible due to data flow. In addition, the second structure of the event is set to "lock the front panel until the end of the event. Given that the event cannot end as explained above, the façade is locked up forever.

• Help with State Machine user Sequentail events

  I'm trying to create a program using the state machine which include events genreated user to jump between States. Also, I want the program to require a sequence of events to be genreted before entering in some States.

  For example:

  States: Init, idle, a-1, A-2, A-3, B - 1 and stop

  If a-1 State is selected, the user must enter the setting and select the condition A-2.
  The user cannot directly jump without having to access the mode a-1 to A - 2
  If the user selects the a-1 State, he should have the possibility of not input parameter and jump to another State as B-1 or Stop

  State A-3 can be entered automatically by State A-2.

  How to program the machine in order to do what I want? I've updated a sampling program. I'm not sure if I impleted the program properly. The user Panel hangs if I enter State a-1, and then press the Stop button. It does not allow me to leave the a-1 State and forces me to go to State A-2.

  A few other questions:

  -How to initialize all values of boleean to 0 during my Init State?

  -Why is a timeout value?

  Hey there, I developed example of Jacobson on a bit here to illustrate the case "Idle, how far to walk, ' your state machine diagram.

  Some keys on the front panel when you are in the bad condition will do nothing, as you can see, because I only check for buttons, I would like to respond to each State. For example, by pressing "Start on" the State of market won't do anything because this isn't a valid button, but pressing "Quit" will bring you to Idle. To implement the rest of the state machine, it is up to you!

• logical AND with the structure of the event

  Hello world

  The structure of the event can manage several events at once to do the same thing: looks like an OR logical operator. But I have not found a way to sequence events to approach a logic and example: you must click on a button to draw, then enter the image would change the mouse cursor. With a structure of the event, I can handle these 2 events separately or together (i.e. change the cursor), but I can't do a sequence of events.

  Is this possible to do with a structure of the event?

  I hope that I am clear (sorry for English btw). And thanks in advance.

  Christophe

  I don't think this is possible directly. You will need to add status information to your event loop that could enforce the order of events and the rules of logic you want. Where transformation you would have to check whether the required event has occurred before this event. If that were the case, perform your treatment. If this isn't the case, ignore the event. Your first event would need set this status information. You can also include some kind of time-out for the second event were to occur within a specific period.

  This type of logic may be better treated with the help of producer/consumer architecture and a state machine in the task of the consumer.

• In the case of flat sequence LED

  Hello

  I have 2 flat sequence event with 1 LED in each event. How can I turn on the LED when the start of the event and the OFF when the event ended before he will move to the next event.

  Help, please.

  Thank you

  Those who are not in the sequence of events. These are individual images. Events in LabVIEW are something completely different. Based on your question it seems that you are not completely understand dataflow. A function/VI will run when all data on the cables connected to it is present. Stream can be used to enforce the execution order, but executives of sequence can also be used.

  In your first picture if you wire a real constant for the Boolean value, you can control when the Boolean value is updated because there is no dependenct data between the numerical calculations and writing of the LED. So, if you want to turn on the front LED the first image, then you must add a frame before the first person where you set the indicator and the same thing at the end.

• Vista - Shutdown - problem event name: the BlueScreen OS Version: 6.0.6002.2.2.0.768.3 locale ID: 1033

  I almost didn't post this because there are so many entries with this error. But after about 20 minutes of research, I couldn't find one that was exactly what happened to my computer.

  I use a laptop Dell Inspiron 1501 with Vista Home Premium. The computer is a few years old. I've never had a blue screen before. I always run the MS. updates I run a scan for viruses from McAfee weekly. I try my best to clean up my computer and stay away from suspicious websites.

  Last night, I was using WiFi cafes of a grocery store. I closed my computer and I got a blue screen with lines vertical white sparkles. Instead of the end of the shutdown sequence, the computer restarted. I could stop from the log in window successfully.

  When I started the computer later in the evening, I received a message window:

  "Windows has recovered from an unexpected shutdown. Windows can seek a solution the next time you're online. »

  The rest of the message is at the bottom of this post.

  I was able to open the file of text below. That is what it says:
  -------------------------------------------
  Windows NT Version 6.0 Build: 6002 SP2
  Product (0x3): Vista (TM) Home Premium Windows
  Edition: HomePremium

  Flavor: Multiprocessor Free
  Architecture: X 86
  LCID: 1033
  -------------------------------------------

  I worked on my computer for awhile. I don't have Internet access at home.
  An hour later, I got the same blue screen when I stopped my laptop.
  The same sequence of events took place: instead of the end of the shutdown sequence, the computer is restarted. I could stop from the log in window successfully.

  I immediately started the computer again. I received the same message window.
  I made a few changes in a Word file just to keep the computer running some time before stopping again. I don't have the blue screen this time. I repeated start-up and shut down the computer several times after that and didn't get the blue screen or message.

  I don't have the message when I started my computer this morning. I use WiFi to a library this morning.

  I should also add that last night when I booted my computer and connected to the WiFi at the coffee shop, I received a message that FireFox has an update. I installed this update successfully. I thought I read somewhere online that the most recent version was giving problems to Windows users. I can't find this article. But I just thought I would add to this detail. I uninstalled FireFox just to be safe.

  I would also add that the strange behavior, only that I noticed when I used the WiFi is that I could not access the MSN.com or HotMail/Live Mail log in pages. The pages would simply not load. All other website worked/load very well.

  So, can someone give me details on what happened to my computer? It's going to be OK? Do I need to run a virus scan? From what I've read in other posts "blue screen", it might be a hardware problem. But, I don't really have a good answer that satisfies me. My computer seems to be OK for now.

  Please let me know if you need more information.

  Sincerely,

  Marz

  We need the DMP file because it contains the single record of the sequence of events that led to the accident, what drivers have been loaded, and what has been loaded.
  
  
  WE NEED AT LEAST TWO FILES DMP TO SPOT TRENDS AND TO CONFIRM THE DIAGNOSIS.
  You may be able to get the DMP files without crashing by booting in SafeMode (F8) with networking.
  If you are overclocking stop.  (chances are that if you are unsure if you are, you are not)
  To allow us to help you with symptoms BSOD on your computer, download the contents of your folder "\Windows\Minidump".
  The procedure:
  * Copy the contents of \Windows\Minidump to another location (temporary) somewhere on your machine.
  * Zip up the copy (compress)
  * Please download to a service like Skydrive or "Rapidshare" to share files and put a link to them in your answer.
