• Sharing data between multiple while loops, competitor rates

  Hello

  I am trying to Exchange data between competitor while loops running at different speeds.  What is the recommended way to do this?    In practice, I have 12 indicators and 3 cards I would update (on screen) in the slower loop, although the data acquired and stored on disk in the fastest loop.  The image below is a simplified version of what really works my candidacy.

  I currently use local variables and shared to achieve this.  I heard however that local variables are evil because of their use of memory (data are copied instead of who passed by reference).

  Thanks for your suggestions,

• How can we enter and update digital panel forward when a young while loop runs?

  Hi all

  In my code, I have a while loop making quick gripping (sampling)

  How can I update other digital controls in the front panel when the while loop runs?

  right now, once I have enter a number in this digital control, the computer seems to be no answer to the elbow. Looks like the computer focuses on the while loop.

  any ideas are appreciated.

• Stop the multiple while loops in the acquisition of Vision

  Hi, I want to close multiple while loops with a STOP. I use the software for the Acquisition of the Vision for the recording of multiple cameras and I would like to finish this record from all cameras simultaneously. I don't know how to do this since I am knew to LABView. I would add my VI here and maybe someone can help me.  Thank you!

  A local variable should be sufficient for your application. Read the following article:

• Producing a XY chart in a While loop that adds a new point XY to the curve from each while the loop iteration

  I would like to plot data by using the XY graph as a Visual display. I have a While loop that creates a new point X and Y during each iteration. I need the XY graph to be in the While loop, because once the order to stop has been pressed the sis loop finished and the final graph to be displayed. The problem is that after each iteration, the XY graph display clears and watch point, compared to add the new point to the previous by a line connecting the two points. It works perfectly if I move the XY graph out of the While loop, but it only shows the XY graph at the end of the While loop. I would like to visually see the XY graph updated during the execution of the While loop. Any help would be much appreciated.

  Thank you

  You can add a data both point to a chart to a chart, you must pass the entire data group.  I would use a couple of shift registers in your loop.

• How to restore a database to a different server, do not use the catalogue

  Hello
  
  
  I have to restore a database to a different server, but without using the catalogue, i.e. I can use the control as a repository file.

• HAVE multiple AO-synchronization-2 multiple while loops

  Hi all

  I want to characterize my RF circuit by using an additional narcotics control and map PXI-6229. I wrote a simple VI in Labview, which is almost similar to the example, multiple-HAVE-AO-synchronization, seen in LABVIEW. According to my VI, 4 analog outputs with different offsets dc, amplitudes and phase values must be generated to my RF circuit and 2 analog inputs must be acquired by this circuit simultaneously and continuously. But the problem with my VI is that I try to observe two diagrams at the same time to see the changes in signals generated and acquired. However, I don't see the two signals simultaneously. The second while loop, which belongs to the acquisition of analog signals, does not start while the first loop generates analog signals continuously. How can I synchronize these two while loops in order to observe the two parties in the diagrams?

  I have attached my VI.

  Thanks in advance.

  Hi Eray,

  I will be brief and I'll keep it simple. If I understand correctly, you have trouble with the data stream in LabVIEW. When you work in LabVIEW, you must understand the order in which the blocks (functions/nodes/structers) are run in LabVIEW - stream. Each block can be executed just at the moment where there values on each entry. This means that if the 2 blocks are connected with a wire, the 2nd block waits until the first ends its execution.

  In your case, that means, this 2nd loop does not execute before the first loop (with the DAQ Assistant) ends its execution, because the son comes from the inside of the first loop, then they go to some DAQmx features and then DAQmx features they go to the 2nd loop.

  In principle, what you could do is to put the content of the first loop, where you prepare the signal generated in the 2nd loop. Good course without the DAQ Assistant. Instead, you can use DAQmx writing in the 2nd loop.

  Kind regards

• Synchronization of multiple While loops

  Hi all

  I work with 4 all in curls that are independent from each other that is, there is no data flow in one loop at the other.

  I noticed that every while loop takes different time to iterate.

  However, I want to while loops to begin and end at the same time after each iteration.

  How can I synchronize their?

  Thank you for your response.

  Aveo

  Hi Aveo,

  You can use a few 'occurrences', 'Notifier', or "Rendesvouz" to synchronize your loops.

  Or use timed while loops - they can work in harmony...

• Stopping at two while loops, running with queuing

  Hi all

  I'm using labview 8.2.

  I have two while loops in my code (called the main loop and the other average loop - seen on the screenshot file).  I just want to stop both the while loop at the same time (it's ok it the average loop takes a bit longer).  I use global variables to stop (as I have tried the local one, but I don't think that LabView sees in the middle of the subroutine).

  Please give me some suggestions on this.

  Is attached a screenshot and my labview code

  Using a ' functional global' is almost identical with a "global" variable Indeed, before the existence of "global variables", a functional overall, it is how people have this feature.

  The usual way to stop a loop containing a "wait for queue ' is to destroy the queue and use the error on the terminal of the 'expectation of queue' directly in the terminal of the judgment. In this way, you don't have to queue up some kind of end the command to stop it.

  Add a queue to destroy after the stops 'main while loop. Delete the global variable and the error from the stop "waiting in the queue" in the loop "average" it is wire terminal.

  General advice, always try to avoid using local and global variables.

• start stop multiple while loops

  I have a fairly large VI that works while several loops with the strutures case inside.

  I would like to be able to close and on all looped programmatically according to events. (complete cycle or cycle started)

  I need to store my data in a table, but whenever I turned off the while loop data I gathered is lost.

  It goes like this-measure analog voltage - put it in a digital indicator... now I want to put it in a table only once by my machine cycle.

  If the opeator push the reset button, the table is available for acquisition of report generation.

  Any help would be appreciated.

  Thank you

  Hi type'ssteel,

  I can't open your vi at the moment, but as you say, you can use the terminal i. For iterations, you must add 1 to it. I start with 0.

• Acquisition of data using the single cycle timed loop in labview fpga (7833R target)

  Hi all

  I want to acquire data of input analog of a generator using the loop of the timed cycle and DMA FIFO funtion. I want to use the acquired data to act as a process for my PID control variable. Can the attached code perform the goal? I'm skeptical about its features. Advice or suggestions please.

  Kind regards

  Opuk

  The SCTL does nothing for you here.  Just remove it and write directly from your analog read the DMA write.

  And on the side of the host, you must move the Run method for before the loop.

  You should also consider to the PID in the FPGA.  PIDs work best in a deterministic environment, and you get more deterministic than on an FPGA.

• How do you get Lightroom CC on my new iMac? I currently use it on this iMac 1 and want to use it on the new. I am using a different email but address using the same wi - fi connection. Thank you.

  I just bought a new iMac, and after setting up, I need to find a way to access the Photoshop and Lightroom CC CC. I am using the same airport and wifi but a different e-mail address, if that matters. ?

  Hi Captainlenny

  You must first download Creative cloud Application Download Adobe Creative Cloud apps | CC free trial Adobe

  Then sign in with your Adobe Id (The same Id with which you bought the map) see connect and disconnect to activate Cloud Creative applications

  • You cannot use a different Email address to connect
  • If Creative cloud says "you are already you connect to maximum authorized devices" select " sign me out of all the other thing ' so that you can connect.

• How to run a web application in JDeveloper11g using the jdk 1.4.2_04

  Hello
  
  I'm trying to run a jsp/servlet web application in JDeveloper 11 g which was developed in JDeveloper 10.1.3. I migrated the application for JDeveloper 11 g and when I tried to build the project, it is throwing an exception as * "' error: project is not configured to use at least JDK 6. * after changing the version of jdk 1.4.2_04 for under project properties/libraries & Classpath/Java SE Version." There are other parameters to change? Can someone guide me on this.

  Hello

  JDeveloper 11 g is a JEE 5 environment (so according to JSE 5), including medicines generic and other features. It so there's no way that you will always be able to run using any environment 1.4.x.

  Kind regards
