untriggerred event(e-fgv)

Hi guys,.

I have questions about triggering events of efgv (functional global variable of event, I don't know if it's the standard name that people use... haha). We discovered that efgv is quite handy. But the more we use it, we realized that certain events are not triggered.

I created a (Test EFGV.vi) VI for you guys to run it. Basically, there are 1 headband that will trigger the event 50 times and supposely any events on the various nodes must be triggered to 50 times more. However, when you run the VI, each triggered loop iteration will be different. The VI loop 1 trigger and 4 loops to-be-triggered, even with what we normally do on our application: 1 will trigger many.

However, there is also efgv that 1 is designed to be the trigger of 1 to 1. And I realized that the problem occur again but much less frequent. For example the previous project we have intermittent problem on this point, where, in a month, the efgv was not triggered only once.

Anyone know why this is happening? What I did wrong with the program? Hope you guys can help me on this...

Thank you...

You may not use the same event record refnum among several event structures.  Each needs its own thread for reference.

  • Independent cursors on the Board of the cluster of graphics (or work around)

    Hello

    I've been using Labview for awhile, but it's my first post here. I was try and research (on this forum and others) for a work around for my problem for a long time. I have an application that requires two layers of data selection. The first selection fills a 'table of groups of charts XY' dynamically using two cursors on a picture of intensity.

    Then I need to independently select data using the sliders on each of the generated graphs dynamically in this "table of groups of charts. However, I found that this is not possible because I can't use the sliders for each chart independently because they are essentially "the same graph.

    I am in desperate need of an elegant solution to this problem. I'm working on Labview 2010.

    Here's what I have considered:

    (1) I have considered using a graphic with plots separated by using the option "stack trace" but the graphs do not sliders.

    (2) I have reviewed several plots, and to play with the visibility property, but this is not necessarily dynamic because I would have pre allocate maximum plots, no I don't think that this solution is elegant.

    (3) I have regarded as a graph of mixed signals, but it's not dynamic because you cannot programmatically add and remove groups for the chart.

    (4) I plan to do a custom/indicator chart control that processes data as well as sliders?

    (5) possible to use labview OO to accomplish this?

    I have attached a dismantled version of the program with just the table of groupings of graphics with the sliders on them to give you an idea of what I'm after. I need to be able to control the sliders independently on several graphs that are produced during execution, it is absolutely essential for the application. I also absolutely need to have the ability to dynamically size the number of graphs running.

    Guru's out there who can suggest an elegant work around for this? I would greatly appreciate!

    Best regards

    You can try something like this - http://forums.ni.com/t5/LabVIEW/User-interface-problem-list-of-clusters/m-p/2311770#M726599

    Indeed, it is an 'array of sub-panels', where each school can show a completely separate chart and you put the management code in the Subvi. The main question for you would probably be that you need to move data to and from the EIS. You can use events or FGVs for this (with events you can use an event and include the data of ID in there, or use a separate event for each VI and do a search for its reference.

  • 24 v digital signal of the event from the host to the fpga power on/off

    Hello forums or

    Sheet material

    cRIO-9074

    module or 9472 digital module 24 V output c series

    To expand on the topic described,

    I want to be able send a trigger to alarm the fpga digital 9472 out that lasts 30 seconds using the operating system time real clock time on the host computer

    The way I approached this problem is that

    In the loop where the event occurs, if the event trigger is defined then the fgv has a time stamp when the event occurred is sent.

    In the loop that communicates with the control of fpga, I write to the control based on the condition that the difference of the current time checked and fgv time is 30 seconds or less, then it will send the value true, otherwise send fake and wait for the next occurrence of the event.

    The main problem after implementation of this is that 9472 led does not turn off when the false value is sent to it.

    cordially Mzamanstl

    Timer Keeper SD is a FGV so that it is written for her, once the event occurs

    So if the event occurs so timestamp is stored and then the difference of the timestamp result is<30>

    then a true value will be sent to the module of 9472

    So basically I want the light and I want to do the 24 v output for 30 seconds then turn off and wait for the next occurrence

    I think the method that I test it with is not very good, because I realize other factors that may contribute to this problem, so I think I found another way to test

    and I will try it but its will take time.

  • Error 1 to generate the user event

    I have a master/slave VI tester to evaluate the functioning of a Global functional error which should gather errors are generated in each loop.  I get 1 error: invalid parameters to the user events VI generate in the FG of entry error and do not know why.

    I enclose my (LV 8.5) shots of screw and screen, because I think that images would explain better than words.  I have documented the code to indicate what should happen and what is happening.

    Please let me know if you need more details.  Thank you! Your help is appreciated!

    In the case of initialization of your VI main, you're going to initialize the FGV Subvi error.  But you can't give the refnum of user events to store in the shift register.

    When you use this FGV later, it uses the empty refnum into the shift register and sends that to generate the user event, and it gives an error.

  • FGV in a packed library doesn't seem to share data

    Hello

    I have a main interface VI showing in a secondary control panel front of the screws stored in a packed library.

    Initializing the main interface VI, I create a user event and store its reference in a FGV. This event is logged and then by an event structure in the main interface VI

    .

    FGV is stored in a lvlib, this lvlib is referenced as a source "still included" file in my libraries packaged relies.

    However, generated event of the displayed VIs (inpacked library stored) are never taken trapped by my main interface.

    Is there a reason for this behavior?

    Application must create a single element with a unique identifier queue and queue data and then start or load the PPL.

    Design ensures both PPL asking knows and returns the name of the Unique identifier

    PPL VI must use the same identifier and obtain the queue and then get an overview of the data. It is one of the solutions.

  • Referencing non-event source enum

    Hi all

    I want to take three dynamic stream of a triaxial accelerometer and reorganize who is x, y and z, based on overall accelerometer orientation so that the global axes remain the same, i.e. If I reposition the accelerometer so that its tip axis now in the global sense, 'z', ' y', I want that data to be bound to the z wire so that saved data is consistent. In the past, I just changed the name of the file, but this solution is quite clumsy, and I already know how this is not interesting.

    I have yet not done anything achievable, because I'm just confused so no example VI unfortunately. All I have is three emuns labeled x, y and z, each with x, y and z components of choice, as below:

    For example, I put the x enum item in there. I want the item there should be disabled for enums y and z, and I want the input data x to link to the output data stream there. If I choose a second and then the third element enum is forced. It sounds simple and I could do in order using the nested structures case but it's not very flexible at all. I had a go with a structure of the event, but I can't find a way of disabling items in two enumerations that are not the source of the event, and then I have to return the actual stream. I thought the elements should be disabled in a table and using a FGV within a structure of the case, but I found myself with some problems regardless of how I approached it.

    I'm not necessarily looking for complete solutions, but it would be good to have some fresh insight and ideas so that I can have a go myself.

    Thanks in advance!

    IDT

    Hi idt.

    I think you have misunderstood the table that you are inputing in the disabled items property. The disabled items property disables the values that are the indices of the table you fed into it. As you have supplied an initial array of 3 you select the 0th element, which is in this case, 0 x three times and turn it off. If you remove the constant matrix on the left of your loop, this will be illustrated by the fact x should no longer be disabled when executing your VI

    Kind regards

  • How to invite people to an event calendar with the new iOS 10?

    Before I updated to iOS of 10, I was able to create a calendar event with the apple iPhone built-in calendar and there is an option to 'invite' contacts him so they could add to their calendar. I can't find this option now after the new update. Where and how can I do this?

    Invite others to an event. You can invite people to an event, even if you're not the one who, on demand with Exchange and some other servers. Press an event, press on modify, then on the guests. Type the names, or tap to select the people to contact. If you don't want to be notified when someone refuses a meeting, go to settings > calendar, then disable view guest declines.

  • the iOS 10 not displaying calendar widget is not the events

    After the update to iOS 10.0.2, the calendar available on the lock screen widget does not always display the events. Nor the duration of the event or the event name appears, but a white widget with calendar color bar can be seen.

    This is not always the case, but very often. For ex, if you open the calendar application, then check this widget, event, but after that you lock the screen and check again, it would disappear.

    Hello jyothishureth,

    Thank you for using communities of Apple Support. It is my understanding from your iPhone Calendar widget still shows no events. I use my daily calendar to keep me organized. I can understand your concern. I'm happy to help you.

    If you haven't done so already, I recommend that you restart the phone. This can solve many unexpected behaviours. Follow the steps below:

    1. Press and hold the sleep/wake button until the Red slider appears.
    2. Drag the slider to turn off your device completely off.
    3. Once the device turns off, press and hold the sleep/wake button again until you see the Apple logo

    Restart your iPhone, iPad or iPod touch

    If the problem persists, try to remove the widget and adding it back on. Use the following steps:

    1. Right above the home, lock screen or Notification Centerscreen.
    2. Scroll down and tap on change.
    3. To add a Widget, press on . To remove a Widget, press on . To reorder your Widgets, touch and hold next to the apps and drag the in the desired order.
    4. Finally, tap done.

    Use Widgets on your iPhone, iPad and iPod touch

    Have a great day!

  • Events calendar on Mac sync iPhone or Apple Watch

    Input events calendar I have on my Mac don't sync my iPhone or Apple Watch.  Events calendar on iPhone synch to iMac.  in iCloud preference, I've marked contacts, calendars and notes.  All the work schedules.  Any suggestions?

    Option 1) update your calendars and reminders of the app of calendars:

    Open the calendar application.

    Choose View > refresh calendars.

    Try option 2) remove the account in calendar > Preferences > accounts.

    Now add back.

    Option 3) if it still fails to work, try to test in the comments or new user.

    CREATE A NEW USER

    Go to system-> Preferences, create a new user in users and groups.

    Switch to the new user by logging incoming/outgoing or use the fast user switching.

    Connection with Apple ID

    Only select Calendar for this test.

    Open calendar and test by adding an event and see if it syncs with the iPhone.

    You still see the issue?

    If so, see these steps by khati for Installation of Sierra difficulty. I suggest you reinstall Sierra again.

    If not, then the problem is in your user folder.

  • Import emails .ics calendar events

    I recently updated my 5 c to 10 IOS iPhone and I can't import all events in a calendar .ics file into the standard calendar from an email app.

    Previously in older IOS, the method was:

    1. open email with the .ics file.

    2. tap on the file in .ics to display a list of events.

    3. scroll to the bottom of events and press 'Add all' and then select the calendar to which events are to be added.

    Nothing is more a ' add all ' button. I tried to add events one at a time, but appears not to half of the working time.

    I met the same problem.  I tested this by creating a file ICS w / calendar (version 8) on my Mac OS X (el capitan 10.11.6) then sent me.

    Using the default e-mail program, I can see the file but cannot add them both.  Is there another way, we are supposed to do now?

  • Badge of reminders stuck to an event

    I have this weird problem with reminders app on my Mac OS Sierra (A 16, 323). It shows always 1 number of events missed on the Red badge on the app icon in the dock, but I did not all events there at all. I cleaned up the list. I tried to discover through hidden events, find something with the search box, search backward events, use automator to delete all reminders - nothing seems to work. I have to say that I do not see reminders on my iPhone is and no badge here. It seems that this badge stuck only on my MacBook, even if all my devices are synchronized via iCloud. One more interesting thing. Recently, I did a clean install of Mac OS Sierra, and the badge is still there. So I guess that it is not a cache or are anchored related issue. When I disable iCloud in the accounts of reminders - badge will disappear, but it comes after I have activate the account again.

    I had similar problem with my calendar on Mac app. He has been linked with the sharing of the family. We have disabled the family sharing and there was a note on it in the calendar, it was a little hard to find and because of this badge has been featured on the calendar icon in the dock. When I deleted this notification - badge was gone. And I guess, badge on reminders showed up after I disabled the family sharing as well.

    Anyone had the same problem? I mean it's not critical, but this badge makes me crazy because I still think I could have missed something in list of reminders. And Googling for what it does not work with effective solutions.

    Hey there, thiaramus.

    Thank you for using communities of support from Apple!

    I see that the reminders app always shows a missed test badged on the dock, even if you have not all events there at all. I know how it is important to ensure that you do not have reminders showing if there is none. I can help you with this.

    You did some great troubleshooting so far. What I would like you to try now is to test this question in a new user account. Please see the following resource to test a problem in an another user account on your Mac: How to test a problem in another account on your Mac user

    Once you have connected the new user, please login to iCloud and make sure that reminders is enabled. Then, see if you get the same badge icon.

    See you soon!

  • Calendar of future events is not displayed

    Calendar does not show future events in the search & spotlight search also

    Welcome Kevin_lpc,

    Thanks for posting on Apple Support communities. I see that the calendar does not show upcoming events in your Spotlight search. I know how it is to have. I'll be more than happy to help.

    Take a look at this article:

    Use the search on your iPhone, iPad or iPod touch - Apple Support

    In particular, take a look at the end that talks on the parameters. You want to make sure that the calendar is enabled in Spotlight search.

    Change search settings

    Go to settings > general > Spotlight search.

    From there, you can enable or disable the Suggestions of Siri and choose which applications to include in your search. For example, if you don't want to see the results of the research in your Messages app, you can deselect Messages.

    If you don't want Siri or Spotlight to suggest close places, go to settings > privacy > location Services and press Siri and dictation. Under allow access to location, tap never. Find out where you can use the Spotlight Suggestions.

    Take care!

  • Someone put an event on my calendar and yet I have not given everything the world approval.  How did that?

    SSomeone register an event to my calendar and still I have not given permission to ANYONE.  How did that?

    Hello. What is your calendar synchronized with other calendars? Gmail or Outlook for example. Could you have accepted an event from an e-mail? These are the settings > calendar > events are in Active Apps?

  • Why not the preferences of the general calendar for "the day ends at:" only offers the possibility of 'am' and not 'pm '? And alerts for an event from 14:00 activate at the right time, but it's at 02:00.

    The "day starts at:" options correctly offer options of "midnight" through time "am" to "noon". Thus the "day ends at:" should have options starting with "midi" and moments of "pm" to "midnight", but instead, they are all time 'am '.

    And alerts for an event from 14:00 activate at the right time, but it's at 02:00. Maybe it's a consequence of the above.
