• How to pause and resume a while loop with a button

  Hi all!

  I'm back in LabVIEW, after only a few years and I cannot understand, what at first sight seems to be a simple problem!

  All I want to do is have a while loop in which, for the purposes of illustration, I have the 'random number from 0-1' function on the inside, and I want to be able to pause and resume this help from a button. There are a few other posts on the forum that are very similar and do use "event structures. The problem I encounter is that I can get the genarator random number to start the generation but the break will not stop this!

  I have the feeling that I made a stupid mistake - but I can't understand or google my way out the problem! I enclose my solution so far!

  See you soon!

  I did an example (you can drag and drop the image into a labview diagram > = 2014)

  hope this helps (I just did 2 excerpts, it's the same program)

  

  

• Why Ctrl-P restarts a while loop?

  I explore (= teaching myself) how key codes are captured by the structure of the event.  I built a simple test routine (see below) which has a period of 1 second which increments each tick (allowing the program to exit after 30 seconds) and a key down? filter that shows me what happens when I type in various keys.

  When I ran first, I didn't throw it away? Terminal wired and noticed that ^ Q pops up a dialog box 'Leave?', while ^ P emerged from a dialogue box 'Print Screen '.  I wanted to "capture" these strikes to "Quit" and "Pause".  I then wired 'True' to the Terminal, and no additional dialog not popped up (as expected).

  However, I noticed that typing ^ P effect was to raise my time loop (there is an indicator, not visible here, inside the the timer event that shows the current count, 1, 2, 3,..., and when I type ^ P, it restores 1 and start counting again).  I guess that overall the program is restarted, but that he was not aware of this problem!

  Two questions.  First of all, it is documented, and if so, where can I read on ' actions ' of this key combination?  Second, is there a way to 'disable' this behavior and have ^ P considered just a combination of keys, the effect of which is "waived" by the event loop?

  Your meter is reset because we did not connect the shift through the key down event register. There is no way to program restarts.

• Can not on the button while loop

  Hi all... hoping to get a few design tips as I am very, very new to LabVIEW. I got a project that someone else had started and I've encountered a problem that I don't know how to solve.

  I'm using LabVIEW version 8.0.1 and I think my problem has to do with the help of DAQmx in a while loop. In "Working.vi" (including the Sub - VI 'Temp data to CSV.vi'), I copied - and stuck the while loop in a vacuum VI for testing. In this VI, with nothing else, it works - slowly, but it works.

  In the real VI, I can see the data of temperature updated every 4 seconds, so I know that the program is not frozen or something like that. However, by pressing the button "Return to main Menu" does nothing - the image of the button does not show that it is to be depressed, regardless of how many times you click or click and hold the button. I've attached a screenshot of the while loop inside the real VI; I prefer not to fix the real VI (especially because it contains references to many of the Subvi, and it is not currently contained within a LAW degree).

  I'm this coding the wrong way? I have the feeling that it might be caused by my settings DAQmx (continuous samples, 2 samples to read, 250 mHz). The very low rate would be the cause? Is there a better way to have readings of temperature taken every 4 seconds (approximately)?

  You have your case of event the value "lock the front panel" until full?  If so, then no other presses the button will be recognized until the ongoing case event complete.

  It is never a good idea to have a code in an event business that takes a long time to run.  It will make your UI seems to lag or even functional.  Any time I see someone with a while loop inside a case of the event, I'm afraid.  (By the way, I am also concerned all nodes comments hovering over the structure of your event?  What are doing?  Why some operate on the default data?)

  In general, events should take is no longer running then what ordinary person could be expected until they feel like the user interface is delayed.  Perhaps at the top of 1-2 seconds.  You should look at a model of design of producer/consumer with events.  The structure of your event should respond to UI events, then pass orders by a queue path to the part of your program that does the real work.

• While loop with reading of text file - calendar of events in a given period

  Hello world.

  I created a program that if serial interface via a port to a syringe push in my lab. Currently, the program reads in a text file-flow rate values and sends them to the pump, one by one, through various commands. I need to ensure that whenever a new flow rate value is sent to the pump, it does in a specific/hard time for a while. I.e. every 0.1 seconds, changes in flow rate and must are active until the next period. I tried to use a timed loop and I think I've succeeded, but it hogs system resources, so I was wondering if there was a way to do it using the number of cycles or something of this nature. I just started using LabView, so I'm slowly getting the hang of it (easy when you watch my VI!)

  See attached VI. I took orders from serial port and have instead orders display in an indicator. The nested and densely populated while loop contains the commands that need to be completed/last during the period (like 0.1 second).

  Thank you for your time and help!

  Hi, you should read some introductory material on LabVIEW to down the idea of the stream.

  Basically, the data flow in the wires from left to right, and any node will not work until it has reached all of his contributions.

  The thread of the error is the best way to run data streams.

  ***

  In your VI I use data wires, their execution through structures, and forcing the structures to run in the sequence.  Using a structure of sequence you mentioned in your next post will force the two scripts to execute in the order of (the only one we discussed to be in race condition.)

  Similarly, for brevity, I would wrap the EMO and she is business structure in a single sequence and force it to run last using stream.  In this way the user has the most possible time to decide to hit the EMO before she is called by the application.  As it is now, it most likely is interviewed at the beginning of the loop, so if it's the exchange value you won't see results until the next loop.

  When running in execution of highlight you see the order of data flow, but that is not guaranteed to be the same for a normal performance, where the use of the data stream.

  ***

  The counter tick account ms up to a very large number and then "says" reset and start counting again.  I know you want to START the loop as close to every 10 ms.  Yes, using data flow, take the number of cycles first, perform actions, then return the number of cycles.   The second time of the tick read that you are in a nested loop that does not stop until you get 10 or more difference on the number of cycles.

  And, on the off chance that you must achieve "return" on the tick counter comes stops the nested loop then move.  (if the second measurement is less than the first, then the tick counter handed.  If you miss this situation while you'd have to wait a long time for the condition of the difference > 10 in the reunion, basically locked in the loop.

  ***

  You could put the EMO sequence, we have seen, in line with data streams.  Before or after the second control of ticks will not make much difference in terms of 10ms.  I would put it after checking the tick, again give the user more time to hit the EMO if necessary.

  ***

  I put in a queue for the stream error and removed the other stuff.

• Start stop while loop with tab control

  I want to be able to start and stop a while loop by entering and leaving a tab.  I use a structure of the event to do so, but it seems not elegant or the right way to do it.  The only way I could get to the kind of work is by unchecking the lock front panel in case of structure.  I have attached a sample vi of what I have so far.

  The problem is that you can't even stop the program by pressing the stop button until you exit the tab, which is not a user friendly interface.

  The event should just manage basic user events.  Any given event does not take a lot of time to run.  While you are in the diagnostics tab, your code is stuck in this while loop.  Although the setting of the front panel of the lock allows you to do other things, the LabVIEW is just put on hold all these other events of the UI (like Stop button value change) and cannot handle them inside while the loop stops and allows outside while loop to go through again.

  You should have a parallel while loop to manage waveform graph.  You can use notifiers or queues or a motor of action FGV (see Ben Action Engine Nugget) to switch the starting or stopping of the update of the chart of waveform until the parallel of while loop.

• Reset a loop counter and restart the calculation

  I have a while loop nested inside a loop for the calculation of a model.

  Lets say that I am on the loop for counter 4. Suppose that I wanted to keep track of the number of iterations on a while loop, and if it exceeded a certain 100, exit say number the while loop.  I do this to avoid my model of computation being blocked somewhere due to optimization problems. Now, I want to restart the loop counter calculations 4.

  Is there a way to do this in labview?

  Well first of all, if you want to start the same program inside loop after it got stuck is going not only to get stuck again creating a permanent loop in the code? Would you not just to go and have some sort of identifier as one of the loops is stuck?

  But I recommend just nesting your while loop inside an another while loop, and then connect the output to the out-while loop to a variable of the while loop inside, so if optimisation did not appear correctly then it simply repeats the inner while loop.

  

  Although I am of my thoughts that you will end up just straight up in a loop permanent if optimization fails the first time.

• How to do while loop that runs and re - index reset continually

  Hello

  I'm trying to send and read data through the serial port. I'll send separate strings that are stored in a table and the serial port read a value that is returned from my instrument for each string that is sent to it. The table is indexed by the 'i' in the while loop. My problem is, the while loop runs until it reaches the maximum array index + 1, then stop. I would like to have the index restart to zero once it reaches the maximum of 'i' - value, then it returns the values of my table again. It is essentially a program to monitor for an instrument, and I need to continually update the variables in the monitor. I'm new to Labview but is really cool! If someone would be kind enough to help, I would really appreciate it.

  Thank you

• Control and Simulation in a loop / while loop with TCP/IP reading / writing of synchronization

  Hello, I have a problem with reading TCP/IP and written in two loops. The problem is NOT to get the two loops to read and write to and from the other. This has been accomplished. My problem is when I run control and the loop simulation on my laptop and the while on a RTOS remote on the controller on-Board of LabVIEW in a remote PXI chassis, the while loop the remote system running on four 4 times faster than the loop control and simulation on my laptop. In other words, for each iteration of the loop control and simulation on my laptop, there are 4 four iterations of the while loop on the remote system. I need to know how to get a degree of kinship (1:1) with these iterations of the loop. When I run a longer simulation in real time, say 10 seconds, the control and Simulation loop begins to slow, i.e. the simulation time slows down until it is no longer in real time and the "Late Finish"? Parameter is set to true and the LED lights and continues to stay lit. At this point, the system destabilizes due to what I believe is being well sampling rate too discreet and I have to end the simulation. How can I get a ratio of one to one between the loops and also to avoid slowing the loops causing destabilization?

  To give an overview of my application, I implement a control system in a network, seen in "image2.png". This is achieved using my laptop as a subsystem 1. Reference signals are generated from the laptop and the error signal is produced. Control measures taken and the control signals are sent via TCP/IP to the remote system. Position feedback is returned, and the process repeats. My system has Core I7 Procs w / 3 GB of RAM, up to 1 GB/s speed via ethernet and LabVIEW 2011 installed with all necessary modules and networking tools. The attached VI Custom_Wireless_Controller works on my laptop. The remote system I'm working on that has the 7830 NI R Series with FPGA card. OTN runs on the PXI chassis with an enbedded controller that has networking capabilities of up to 100 MB/s via ethernet. I use the FPGA for the acquisition of data and apply control signals to my plant. The plant is the PCE twist connected to the FPGA through the cable of the ECP - RIO of NOR. Subsystem 2 is this side of the CNE. The FPGA collects position, he sends to the controller via the network, receives signals from the network drive and writes signals to the plant power amplifier that operates the plant. This process is repeated and the VI and is titled Custom_Wireless_Plant.

  I appreciate the help really and look forward for her and for any question!

  Well, the first step is to understand what you have set up right now. Your control and Simulation loop on the side of the controller is configured as 'Runga Kutta 4' and you have a loop timed on the other side. In addition, you have the primitives of TCP/IP on the control and the Simulation diagram and means he will perform (a message) on the size of each minor step, which in your case is 4.

  So, you have two options:

  1. replace the Solver side controller Runga Kutta 1 (this must synchronize loops)

  2. hold RK 4, but create a Subvi around two primitives of TCP/IP and configure from the VI to run than the major (continuous) step-size. If you do it right, you should see a 'C' on the upper right part of the VI you have created.

  Please let me know if what I said is not clear...

• Stop and start the task in while loop

  I try to start and stop an output meter (creates pulsed output) in a while loop and I don't know how this is possible. I have a while loop running who is taking measures from a digital compass. If my title is within acceptable limits, the outputs of the meter (2 of them to turn to the left and right) must be turned off. If the title is out of the acceptable range, let say too far to the right, I want to start one of my outings of the counter to activate the object to the left. The issue I am having is that if I put the block 'Start the task' in the while loop the system will try to start each iteration of the loop, even if it is already on. I don't know if there is a problem, but it does not appear effective from a programming perspective. I remember reading somewhere that stop and start tasks can really slow a loop. Any suggestions?

  I actually just to understand it. If you use some if statements and the "fact of task is" block you can make it work.

• while loop: delay enforcement and continuous updated: VI back to fake out of time?

  Hi all

  I want to control the time of execution of a while loop. I want the user to have the ability to decide how long he wants to run the while loop. The while loop is used to update certain values, then it should run continuously, not only run once and wait (that I could easily using the synchronization functions).

  I used the time up VI as suggested in this post:

  http://forums.NI.com/T5/LabVIEW/how-to-create-a-time-control-for-while-loop/m-p/2530212/highlight/FA...

  and works well, but the while loops are integrated into another loop for and when Goes to the next iteration, the elapsed time Boolean result is set to true and it does not run at all (I think that's the problem).

  Can I return the Boolean result of the elapsed time VI to false, after reaching the target of time? That would solve my problem, I think that...

  I attach some of my VI, although I don't know that it could be useful for you...

  Thanks for your help

  Use the iteration for while loops count and an equal to zero? node.  Then the output of the comparison at the entrance to reset the elapsed time functions.  The idea is that reset you on the first iteration (when I = 0).

• While loops and event structures

  Is there a problem using more then one While loop with an internal structure of the event, in a single VI?

  In my (only a partially attached printscreen) VI there is more then 2 all in curls with a structure internal even who controls a different devices.

  Event structures are being controlled by a box structure.

  From time to time the VI gets stuck and resetting local variables.

  

  Hello

  Using two while the loop is not a problem, it depends on how you structure the code.

  Generally, we use two while loop for Producure-consumer, master - slave structure type of applications. Try to use the structure of State machine inside while loops, see standard state machine examples in the palette of NOR find example.
