How to close FPGA reference out from different while loop

Hi Friends,
              I`ve different while loop which performs the FPGA read port on different loops I`ve the FPGA out on every terminal at the end of the while loop. I`ve just connected the merge error function in which all the error out of the FPGA are combined and given to simple error handler. How to close the FPGA Reference.

Can you attach your VI?  I'm not clear on what you mean.  Are you saying that you are using the FPGA reference which is passed into multiple loops, and then continuing the reference wire to pass the ref out of each of the multiple loops?
If that is the case, I don't believe you can't merge references like you can error clusters.  You will just need to wire one of the reference to the close FPGA VI.  Additionally though, I'd recommend that you use your error clusters in some manner to ensure data flow so that all the other loops stop first, and you are sure you are closing the reference after all the other loops are done with the ref.

    Asking how to get out of an infinite loop is like asking how to find the end of a circle. I'm not trying to be sarcastic but by definition, if there is a way out of the loop, then it is not infinite. I think what you are asking is how to avoid creating an infinite loop. Is there something about the suggestions you have been given that you do not like? My favorite suggestion is the notifier but maybe you just need an example. Turn on context help and read about the notifier functions in the code below.
    This is your top level VI
    And this is your subVI
    If this seems too complex then a global variable will work too. But what seems simpler can cause much more complex bugs. You can code fast and spend lots of time debugging or you can code slow and spend less time debugging. Personally I perfer writing productive code than looking for bugs any time.

  • How can I write waveform data from a while loop?

    Alright, I have a NI-5122 high speed digitizer that I need to acquire 10,000 waveforms. I am currently using the NI example code "niScope EX Multi Record Fetch More Than Available Memory.vi" to do this and then onto that later. I set the Number of Records to 10,000, min record length to 8192, and the min sample rate to 100M (S/s). On the Fetch vi,  I set it to get a 1D Dbl array and then send it to the while loop edge for auto indexing. What I want is to take each waveform and write it to a file next to the previous waveform not append it to the bottom of the previous one. I can do 100 and sometimes 1000 waveforms with my current setup and then use "write measurement to file.vi" to save the data, but at 10,000 it says that the memory is full. I have 256 MB on the NI-5122 and 4G of memory on my host computer. My reasoning is that if the NI-5122 can hold all that data then why can't my host computer. I have tried to fetch using 2D Dbl and transpose that matrix and send the data to "write measurement to file.vi" inside the loop and append the data that way, but when I do this the card does not acquire any data. Which seems like a software problem. I know this is probabaly worded poorly, so just post a response if further explanation is needed.
    Thank you.

    Hello,
    It sound like you might have received a LabVIEW: Memory is full message.  Are you also graphing this data as it is being acquired?  Are you building an array inside the loop?  At the 100 MS/s rate, you are using a lot of memory to acquire, graph, build and transpose array data, and then write to file.  If you are saving to file and do not necessary need to see the data, I would suggest taking the graphical indicator out of the code.  Please review some of the KnowledgeBases linked below about the LabVIEW: Memory is full.

    You can!t using af:query. the af:query component comes as is. If you can't do it through the properties, you probably can't do it at all.
    As in your other thread, the way to go is to program your own search form. This way you can use a layout and functionality you like.
    For this you create a form with input fields for the values you are searching for, put them on hte page in a way you like and in the end by hitting on a button (e.g. called Search) map all inputfields to parameters of a service method you defined in your application module or VO. This service method then executes a view criteria returning all matches in the default iterator (just as if you had used af:query.

  • How can I build a table with the time values of a timer from a while loop

    Hi:
    I have a question concerning building a table:
    Every 100ms I read a value from a sensor (while loop with a timer). I would like to build a table with the actual time and the concerning value. For example:
    0msec         1V
    100msec     2V
    200msec     3V
    300msec     4V
    etc.
    If I use the Express VI for building a table, I always get the date and time, but I don't need the date and the time is in the following format: HH:MMS, which is nonsensical for me as I can't differentiate within msec. Can I change the format anywhere?
    Can I also save the table to a file or even to an Excelsheet? How can I do that?
    Thanks for your help!

    Hi Craig:
    thank you very much. To solve the mystery : ) :
    I want to drive a stepper motor with a specific frequency. To get the current degree value of the motor I would like to measure the current time (from the beginning of the move on). (With a formula I get the degree value out of the time)
    Concurrently I would like to get data from a torque sensor and from a pressure sensor. That's why I asked you about the time and the table. The measurement should start with the movement of the motor. How can I do that? Right now I have different block diagrams (different while loops) (see attachment) and I would like to put them in one.
    I haven't done the block diagram for the pressure sensor yet, so there is only the one for the torque sensor and the one for the motor.
    I also would like to set a mark in the table when the voltage value of an analog input gets under a specific threshold value. Is that possible?
    I'm sorry, I'm a novice in LabVIEW. But maybe you can help me.
    Thank you very much!

  • How Do I stop the phone from locking while the navigation program is running.

    I have a Blackberry 9630 V4.7.1.40. The phone is on an enterprise server network through work. The phone is set to password lock after a couple of min. of non-use. When I have the Sprint Navigation program running, the phone locks after a few min and loses my satellite. I then have to type in a password to unlock it and I then get the signal back.
    I called Sprint and they said to press a button after every couple of min. to keep the phone "active". That sounds a little fishy to me!
    How do I keep the phone from locking while the Nav. Application is running?

    Agreed, that is the simplest thing to do... probably much easier than talking your IT guys into raising your timeout.

  • How do I store 4 hours of data and get it out of the "while loop" into a spreadshee​t file for documentin​g purposes? "See additional Text for additonal info"

    What a have is a VI that uses the following SUbvi's, starts with FP OpenVI, then FP Create TagVI, into a "While Loop" which contains a FP ReadVI outputting data into a Index ArrayVI outputting to a Display (DBL). This shows the output of a FP-AI-100 monitoring a 9v battery. I have to monitor this battery for a 4 hour period my problem is storing the 4 hours of data and getting it out of the "while loop" into a "Write to Spreadsheet File VI" all I seem to accomplish is just one data sample which I get into a spreed ship file with no problem. I just can't get 4 hours worth. By the way this is my first VI and I'm self
    trained so have mercy.

    I figured it out thanks.

  • Re: exit from a while loop in sub vi

    I think the mail didn`t get through first time. Repeat posting - Sorry if
    this occurs twice
    Shane
    Hallo,
    Can the use of occurrences solve this problem?
    The Main program can create an occurrence which can be passed to the
    sub-VIs. Upon pressing the button to cancel the loop, the occurrence can be
    set, instantly transmitted to all other VIs sharing which were passed the
    same occurrence. Of course a small handling routine has to be written (say
    a sequence parallel to the executing while loop waiting for the occurrence
    and then setting the exit parameter to "true") but this is trivial.
    I have checked this with a small program splitting an occurrence to three
    seperate VIs and it works.
    If you want, I can send a cop
    y of it.
    It may well be possible with notifiers or something else, but I have far
    less experience with them.
    Hope this helps

    The notifier is probably better than occurence at this case - than it is not neccessry to write a parallel sequence.
    The use of notifier is very simple, just follow an example in Help/Search example -> Advances -> Execution control -- Synchronization -> SubVI notification.
    Good luck

  • How to close a custom form from CUSTOM.pll

    Dear Friends,
    We need your help on the following issue related to Oracle Apps Forms.
    We have a requirement to show a popup message (message should remain open and user should be able to continue working in the order entry form. User use this message as a reference while entering order details) when user enters a customer name or number in the order entry form . This is similar to the Stock Availability form which gets opened automatically when control enters into Order Entry Lines form, where the stock availability form remains open while entering line details.
    To fullfil the requirement, we have designed a custom form with a single text field in which the message text (some customer information) will be shown.
    We are using custom.pll to call this custom form (thru FND_FUNCTION.EXECUTE) when the control leaves customer number field. User could leave this custom form open and continue with entering order details. Till this point we could achieve what we want. i.e. we could show the popup message in the custom form after user enters a customer number.
    The problem is, after the custom form is opened, when we enter a new order for different customer, we need to close the custom form (which is opened for the previous customer) if the customer is not qualified.
    we could not achieve this. We tried using CLOSE_FORM, CLOSE_WINDOW, but did not help.
    Any body have any suggestions on achieving this... Basically, we need your help to know how we can close the custom form from CUSTOM.pll.
    Thanks,
    Uma

    I thing you haven't any (supported) option to close a form via custom.pll.
    For a long time, we have search a solution for the same problem without any result.
