• "Control terminals on component connector not on the level superior. block diagram" to comment on the report of the ADC

  Hi all

  Could someone enlighten me please, what does this comment on the value of the ADC

  "Terminals on component connector not on the block diagram of higher level of control.

  This means that some terminals is hidden within certain structures of the case and does not show not not the diagram without going into the structures of the case or by 'higher level block diagram', it means

  main.VI and main.vi controls must also be connected to the connector pane?

  Thank you

  K.Waris

  On the one hand, this means that they run on your screws VI Analyzer, since it is a warning in extenso you receive.  This means simply a terminal which is connected to the ConPane is not on the top level diagram, IE. within a structure of housing.

  As to why he is often not a good idea to do that read this classic thread:

• Using more of a structure of the event for the same control in a machine to standard reports

  Hello

  I'm working on a test sequence using a machine standard reports in the examples of LabVIEW.

  Part of my test, I displays a waveform on a graphic scale. The entry for this is a PXI-4070 DMM. This goes into a "while loop" update permanently the waveform. The screen simulates an oscilloscope. The test operator must make adjustments while watching this screen. This bit is working and I have no problem here.

  On my front, it has a "continue" button to the next part of the test once the adjustment is done. Some changes are then made to the configuration and the following adjustment must be made the same way, that is to look at the screen, make the adjustment, press on ' continue. Is where I have the problem.

  I tried using the event structures in the while loop the loop stops when you press the button continue. This works for the first adjustment, but when the test arrives at the second stage of the adjustment, the event seems to "remember" and the loop ends immediately.

  Is it far from resetting the event so that the button can be used again in a good way

  Kind regards.

  
  

• There is a report with information on the Structures of the alignment?

  In my system, I have associated projects to the lymph nodes of the Structures alignment (strategy) and I've specified a % Contribution but I can't find in the system a report (special or standard) with the information of the association with the Structures of the alignment project.

  Can you suggest me a report (xls output) with these data:

  project ID,

  name of the nodes of the alignment (strategy) or the name of the path of alignment (strategy).

  % of Contribution).

  I need this information to configure a custom report.

  Thank you

  There are not any direct report now.  I'm pushing to get some soon.  The best I can tell you, it's what I do.  I scratch the screen and copy the columns in Excel.  Everything I do is hold down the SHIFT key and move my mouse over the data.  This captures in columns and you can simply paste (Ctrl-V) in an Excel sheet.  From there, you can create and Excel-based report.

• get the structure of the case reports programmatically

  Hi all

  Is there a way we can get by all the States of a structure of business programming in my VI.

  It should be possible with scripts. As a first step, you can analyze the 'Tunnel of wiring Wizard".

• using the structure of the event in the LabVIEW classes

  Hello

  I'm new in the use of LabVIEW classes, so don't know much how I can use them.

  In my main program, I have clusters with five elements in each. The elements are controls two States and in some groups, there are three States controls. The user will press the buttons (controls), and different things will happen. In my first program were I not using classes, I had a structure of the event and the controls were cases of event in the structure.

  Is it possible to somehow use an event of cases in one of the methods that is created in the classes, so that say, that's not in the main program?

  I have attached two photos: I wanted to have a structure of the event in servoTouchEvent (in left.tri.lvclass) who is a child.

  Let me know if my explanation is not clear.

  Grateful for the help!

  Hello

  Yes, you can have a structure of the event in a Subvi rather in your main VI of top-level UI. The trick is to use the 'Save for events' and passing in references to orders that you want to have the event trigger structure for. The refnum output since the function is entered in the terminal of dynamic event of the structure of the event who could live in a Subvi. You can add instances of event where you will see these control events as dynamic events then you can do something with. These excerpts from shows all the code in a simple diagram, but the stuff in the structure of disable diagram could easily transformed into a Subvi:

   

  All this can be done without classes. What will buy classes you include the ability to encapsulate your screws and also perform different code based on what object on the hierarchy of the parent-child classes is on a wire. If the behavior of your code is different between 2-3 State and controls (which I do not know what state controls 3 you are referring), you can take advantage of the classes.

• Structure of the event in primary vi and sub - VI with queues

  Hi all

  I have an application that uses the architecture of producer-consumer in which a queue transmits messages of a main VI by a Subvi, in response to the events of the user in the front panel. Inside the Sub VI, the queue is removed and treaty based on the corresponding message, and the result is displayed on the façade the sub of VI. User events are captured in the main VI using a Structure of the event. This works as expected.

  However, I also the controls on the Panel before the sub - VI to change the queue. My approach is to have another structure of the event in the VI sub for this. However, while the events in the main work of fine VI, events of sub - VI never treated.

  A simplified sandbox VI of what I'm trying to do is attached. As you can see, the main VI events are triggered as expected, but events in the sub VI are never triggered.

  I watched this white paper: detect an event in a Subvi from a high level VI , but it's not exactly what I'm trying to do. Instead, I'm just trying to detect an event generated within the Subvi. I searched this forum and found some research related, but none of them seemed to answer what I'm trying to do.

  Thank you

  Matt

  Your major issue here is the loop location.  While the structure should be inside the Subvi to make a message in the appropriate queue manager.  In fact, you should have 2 loops within your Subvi: 1) the QMH and (2) of the event loop.  You must use a user event to congratulate the event loop in the Subvi to stop.  You should NOT use the time-out of the Structure of the event unless you absolutely must.  And since everything in the Subvi is the message function, you do not have expectations.  They will be inactive (no CPU using) when there are no items to process from the queue or queue.

• structure of the event + while loop

  Hello, I am trying to understand how to unite two while loops in attached VI for half a day

  The first loop creates a state machine solid which reacts on each key and runs one of the structure cases. (that part works very well)

  The second loop, always generates the random number, but it stops the generation during the time where one of the structure cases events are executed. (this is the part ticky)

  Any suggestions?

  If you want your random number to stop so that the user triggered events are running, you should be able to simplify your design a lot.

  It can be done with a loop using the case of timeout.

• An interrogation continues with the Structure of the event, please help me understand

  Dear Forum,

  I'm 3 months in LabView. I created a front panel with what I consider a reasonable set of code below with a basic entry control power boulean a case controlled set of actions. I enclose a strongly striped version to the bottom of this structure with sections deleted button so that the executed code is removed to simplify just ask questions on this control structure. After the recent webinar, I understand this form of control to call a continuous structure of vote - and it makes perfect sense and seems natural for me to the point of programming of data flow.

  But according to the webinar it is preferable to use the structure of the event.

  However, the structure of the event seems really weird to me. My main question here is certainly the structure of the event MUST be voting each of the values itself anyway, otherwise how does he know that an event had occurred?

  So what is the difference between explicitly "polling" the buttons myself with a while loop and using a complex (for me) of the event with 'hidden' polling stations under?

  The vote of the 4 buttons in my example should be done at the same time if Labview is truly multithreaded/parallel? There should be no difference in the level of the computer between my code querying and the code 'hidden' the structure of the event making the mark.

  Thank you in advance for you help to clarify my confusion.

  Sincerely,

  Robert Gibbs

  BONE is already this process in any case.  If you are in fact doubly effort without worrying.  And the OS is much more efficient that your code will be.  So just let the OS do work heavy while your code sleeps.

  And think about the trigger more as an alarm clock.  You are asleep (do nothing, with no CPU) when your alarm goes off.  You wake up and perform the task that the alarm tells you to do.  Once done, you are waiting for another alarm, so you get to sleep.

• How to stop queuing in the structure of the case

  I'm trying to find the Summit and the Valley of the signal. I'm able to find it, but I don't want to make the zero with the pic. I just want to get the value of Ridge and Valley. Is it possible to stop queuing the values in the structure of the case? As I have a several signals which peak/Valley must be found that I can't use the library functions.

  First of all, and more which has been mentioned, there are serious shortcomings, making the Subvi is not very universal.

  • Your Subvi does NOT export the correct value of the Ridge (or Valley), but the value just after (which is more a peak or a Valley!)
  
  
  • Your Subvi is only the positive peaks and valleys negative. This seems very restrictive. In general, you could easily have a Valley even if all the data is positive. Right? (With the exception of the Valley of death for example, most of the valleys are above sea level, for example )
  
  
  • Your code is extremely complicated, with two sets of structures of the case, each stacked three deep, four change records and tons of comparisons. Here is a simpler version. (To imitate your outings, place a statement select after each comparison and output the value or zero depending on the result of the comparison).

• Structure of the event in timed loop

  Quick question on the structures of timed loops\event

  What is a good or a bad idea to use structures of event call loops - as opposed to while loops. ?  I guess I like the idea of call loops - because you can prioritize them - so if there are some important things you need priority of 100% in the background - but for the user interface, you can configure it to run slower\or run to a different priority level.

  I just wanted to check it is not a reason why I shouldn't do that - since all the examples don't do that.

  JP

  I don't think it's a good idea. Your timed loop can stop waiting for an event. There is no advantage of placing the structure of the event in a timed loop. It is possible to assign priorities to other objects outside of the call loops. For example, you can the priorities given to subVIs. I'm reasonably sure that the structure of the event can work at other priorities if you do not the activities of the user interface. Maybe someone of NOR can confirm this.

  But the goal of a timed loop is to have a deterministic periodic job. The structure of the event must be used for asynchronous events. The two disagree with them if they are in the same spot.

• Cannot use Global Variable in the Structure of the event

  I'm using LabVIEW 2009.

  In my LabView project, I have a global Boolean variable called EStop. I can read and write the global variable. If I double click on the global variable, it takes me to EStop.vi which includes a text button. EStop.vi is part of my project.

  In one of my report, I have a Structure of the event. If I go to one of the event handlers in this case Structure and right click and select Add event, I get a list of possible events. But this list does not EStop or an EStop events.

  I would like to add an event to EStop case: changed value.

  Why I can not add to a case of events events that include events on Global Variables as value changed?

  How can I add EStop: event changed my structure of the event value.

  
  

• pop up in the structure of the event interrupts execution

  If I place a pop-up Subvi in a business event an event structure and this pop - up Subvi contains a while loop and a stop button that this would stop all loop (which closes the Subvi), will be other events reported in the case of structure be handled until the user has clicked the stop button on the Subvi? If so, is there a way for other events to handle while the pop-up Subvi is still working?

  Yes, it stops while you started VI until the popup VI returns. The events will always be put in the memory buffer, but they will not be manipulated by the structure of the event, until your popup is closed (assuming that your pop up is modeless). If it is modal, the user will not be able to click on anything anyone at all, except the controls on the pop - up's.

  If you still want the user to be able to interact with your façade while the pop up shows and have the FP to answer, you want to launch the popup dynamically in its own parallel process. If you use LV 2012, you can use the asynchronous call starting node. If you are using a previous version of LabVIEW, you will need to use the 'Run' method with an invoke node.

• Sub - Entered VI buttons activation do not Structure of the event

  Hey everybody,

  I have anissue with a Subvi, which takes a user file, play with the type of path of file data until it is in the form of a string, and then puts it in an array of strings in a list box. The issue I'm having is that I created the entries and exits to the buttons in the image, but the case event structures they control are not running when I press the buttons that are connected to the terminals of the Sub VI (the buttons move up one level in the image below).  They DO not work when I use the Panel front of the Subvi rather than on the front of the VI Panel that comes up to the next level.

  So far I have tried:

  -Move the buttons in the while loop

  -Move the buttons in the structure of the event

  -Case change event handling to run on a mouse click of the button from a change in value

  Thanks in advance for any help anyone is able to give me!

  Yes, writing a value to a Terminal never causes a value change event.  Think of it as an event "user has changed the value.  To trigger an event value programmatically, you must write to the Value property (Signaling) of the command or the change indicator.

  Values Boolean locking belong in cases that handles the VC event.

  You could read the terminal (use a local variable) before the time compare loop to the last value (use a feedback node) and use a case structure to determine if you want the event to VC based on the value passed in the appellant.

• In the use of style/Structure of the workplace guide

  A two part diagram is attached.  Half upper is in Place Structure of the element that surrounds the loop.  The lower half has in Place Structure of the element surrounding only the part of the portion of the structure of a table element that has changed.  The smaller square structure element is the only place that the elements of the array are changed.  Since I am new to the use of in Place of Structures of the item, I would like to know the pros and cons for both methods of changing data encapsulation.

  There is no advantage to the use of the Structure of the element in Place in one of these diagrams.  Try to use the tool 'Show buffer Allocations' - you should see that LabVIEW is not a copy of the cluster even without the International preliminary examination, so that the operations are already in place.

  However, you might get some performance benefits to move the "Orientation" table outside the loop for, unless you actually change it all in the for loop runs.
