Means PtbyPt in a loop with parallelism

Hello

Can someone explain to me why this does not work as expected? (values 10.5 and 0.5)

I got 5.5 and 5.5.

I checked the MeanPtbyPt.vi, everything is cloned, the vi himself is set to pre-allocate clones. I also tried to "Inline", does not help. I tried C of 1 and 2, no luck. If I open ptbypt average during operation, I see that the SR holding the data table is interlaced with 10.5 values and 0.5, as if the two clones use the same space memoty, but on the entrance, I still see only ~0.5 coming. What gives? I thought parallelism will create two clones, no?

Hello guys,.

Thank you very much for your answers!

The problem with the 2 ptbypts on the block diagram, it is that I have a table of measurements independent of N, where N is large and variable.

Why a loop with parallelism does not clones? This significantly decreases its value then. I have to rewrite mathematical libraries AND then

In fact, a loop with the parallelism (or without) CAN create clones.  But he must know the trick.

Here is an example of what you "really want".

    This means that we cannot run with parallel option swap partition when we do not include the index of update?

  • How to exit while loop with delay schedule?

    I have a pretty heavy program that iteratively takes a series of measures from a number of channels using a variety OR-Switch and OR-DMM screws that I assembled as a result of various examples and several help pages. Each channel is sampled once during each iteration with data to be saved in a text file for later analysis, after it is imported into Excel. I added to the screen 'real time' indicators and charts to see what looks like running data.

    Each iteration is performed using a While loop with a delay timer, even if a previous version, I used a timed loop. Measures for the series of channels are collected with a loop For inside the While loop. The loop For includes screws which:

    1 cut the channel and wait as debounce.

    2 Initializes the DMM and passes the configuration information.

    3. wait for a while to make sure that the DMM is set.

    4. measure.

    5. close the DMM.

    6 disconnect all the switches.

    The terms of the election of the channels is ends in 15-20 seconds and I am currently collecting data every two minutes, so he spends "wait" time "collection". Each iteration of the loop For initializes and closes the DMM to avoid the hot switch.

    Other components of the program are configuration setting controls, etc. (in front of the While loop), a "current measurement" indicator and a writing-text inside the loop file operation For, several indicators of the iteration (inside the While loop, but outside the loop For) and a bunch of operations related to the grouping and table that provide graphics of groups of time vs measures.

    I don't know there are more elegant ways to perform many functions that I do and I'm not posting the VI here because I want to concentrate on what I know, it's a big problem with my program (for now!) - I can't figure out how to get out of the While loop. I tried the combinations of Boolean control, its conditions of latch and Stop / continuous if true to nothing does not.

    I want a 'Stop' button that ends the While loop, at the next opportunity, but it is not working properly, I think, because the stop button does not play with good timing, because the program runs either the loop For or the time delay at the beginning of the While loop. 'Next opportunity' can mean 'Immediately', 'at the end of the next iteration of the loop,"or"at the end of the next delay schedule." I think that if I get one of these scenarios to work, I can get an any of them to work!

    Help, please!


  • any event loop with a different time

    Hello

    I write a VI which is a state machine that is running at the time of 30ms, but while the state machine is in the idle loop I need to send a rocking live Dungeon (Boolean) a controller every 500ms. With the requirements of the state machine main to run at 30ms how to set another time or the event inside the while loop. I used the rest / function quotient with the iteration but cant seem to find the solution there.

    If requirements:

    • While the loop should run at 30ms
    • every 500ms Boolean value must change state
    • the time of 500ms shouldn't slow down the main loop as a waiting

    Does anyone have a suggestion?

    Hello Bill_lewis,

    As 500 is not a multiple of 30, it seems difficult to run a while loop.

    You must use another loop in parallel or change one of the two calendar in order to toggle your Boolean to a multiple of the while loop timing.

    Kind regards.

  • Reinstall Windows 7 with Parallels

    I am running Windows 7 with Parallels on an iMac. I am asked to reset my password, but I did not have (or remember) my password. I have not created a password reset disk, so I have to reinstall Windows. I have the discs and the product key to do so. The problem is, when I insert the Windows disc and try to run the program installation or auto run, it tries to start Windows and push me to reset the password. How to uninstall Windows on this iMac and then reinstall it. (I tried to reinstall Parallels, but ended up in the same-loop).

    In fact, I have not. I am using Parallels support, who told me to ignore the reset password dialog box, leave all the fields blank and just click "continue". In other words, I have no password and does not require one. It has worked well. Sorry for my confusion on something so simple. (I'm still new with the Mac).

  • Using repeat with... in... Loops with lists of properties

    I am using a loop "repeat the operation with the variable in the list" with a list of properties where properties are symbols, but it doesn't seem to work; It falls right through the loop. Exactly the same code works when passed a list of properties where properties are integers.

    Of after the description of function AW7 repeat with in:
    Quote:
    Repeat with X in the list repeats the instructions in the loop with each of the elements in a list. Each time through the loop, the function sets the next item in the list or the following in a property value to the specified variable. As Authorware estimated the list with each pass through the loop, the instructions that modify the list inside the body of the repetition can affect the loop. Authorware maintains a reference to the list of origin for the duration of the loop. This means that the list persists at least for the duration of the loop.
    Syntax:
    Repeat the operation with the variable in the list
    (s)
    end repeat
  • several loops with error handling and controll

    Someone knows how to do this?

    Two other methods not mentioned in the otherwise excellent document that mentioned Matt are the use of a global variable 'stop all' and a relative using a Global Variable of VIG/functional.  The reason to talk about, is that they can be used also stop 'detached' live, live which are defined to run asynchronously (and therefore a bit 'out of control') regarding the main VI.

    I use a "combination of ingredients" for some projects I'm developing using LabVIEW 2016 and its support of the channels.  For example, I use a Messenger channel to create something akin to a message in queue manager.  When the event loop detects that the exit button has been pushed back, it puts a Message "Exit" on the channel of Messenger and stops himself.  When the Message Loop sees "Exit", it sends one release Message who else has need to see (in one case, the producer of a producer/consumer model) and stops himself.  When the producer Gets the output Message, it puts a "last element is invalid" on the flow of the channel for consumers and stops himself.  When the consumer gets the message of the last element, he stops himself.  A magnificent waterfall.

    And I work (not yet 100% complete) how to extend this to start the asynchronous calls that do not (yet) support channels as easily...

  • Treatment in time loop with microseconds.

    Hello

    I am make only one application in Labview where I capture the image of a camera and image processing. The camera is communicate with the Board of Directors NI PCIe-1433 in the PC with the camera link. This device can operate with a rate of 2000 frames per second. For the treatment of each image in the pc I need a time loop that work with microseconds. The problem is that this time loop only works with MS Windows. If I use the real time module, can I configure this time looping with microsecond or is there another solution?

    Thank you

    Hi xisco,.

    with LabVIEW Realtime, you could create a loop with the order of a microsecond wait States.

    BUT:

    Why do you think you have need of these wait States? What is the purpose of these expectations?

  • Stop the loops with a button

    I have an infinite loop is and display of data. How can I end the loop with a button or a keypress?

    Periodically perform a ProcessSystemEvents() call inside the loop. In a reminder of the STOP button, set a flag to indicate your loop to stop.

    stop unsigned int = 0;

    While (! stop) {}

    data getmeasured

    display the data

    ProcessSytemEvents()

    Sleep (250);   to be polite: it is impolite to spinlock, since you will monopolize the CPU and other threads can get hungry

    }

    then, in the reminder for a STOP button

    STOP the button callback routine

    stop = 1;

  • Bug in the conditional for loop with an array empty

    There seems to be a bug in the loop with a conditional terminal.

    If an empty array is connected to an indexed table auto entry tunnel, a tunnel of output array has an element instead of zero.

    The constant matrix is left empty.

    High loop without the conditional Terminal produces an empty array.

    Conditional down with a terminal loop never true generates an array containing a single element
