Have different conditions for loop start and stop

I do a VI when a circle is moving on an image control and its movement is decided by programming, but also by the user. I have programmed the speed of the circle as a vector which turns (using a rotation matrix) when a certain condition is met. This condition is dependent on the position of the circle and direction as well as other entries. The tricky thing is I want to that when the rotation condition is met (true), the rotation continues until the angle of the vector is equal to the original angle (when the condition became real) + / variable x.

So my question is how do I program a piece of code that once activated, will run until a stop (depending on the State of vector early in the race) condition is reached. As it should be when the VI is on, I can not put a while loop inside an another while loop. Online help mentions also conditional for loops, but it isn't available in my version of LV (8.2)

The correct solution is a state machine with a case inside a single while loop structure. Based on the need to use one of the several cases and move on to another matter as necessary using a state variable (for example, an enum) in a registry change. One of the cases should be slowed down and not do much except maybe controls survey.

There are a lot of models.

Do not hesitate to contact a simplified example of your code and help you.

  • Digital start and stop trigger with restart HW

    Hello

    I am trying to write a program that reads continually samples based on the rise and fall of a digital triggering.  I want the measure to start on the front of the trigger and stop on the falling edge of the trigger.  I want the data that are read to be preserved and then added with the next set of data that the trigger rises again.  I have read the tutorial "Digital start and stop trigger" and can use the reference to stop the measurement process and I looked at the example "Acq & chart voltage - Int Clk - HW Trig restarts ' that comes with LabVIEW and I can get the two of them working separately with my request.  I'm quite confused however try to put the two together (see attachment).

    If I put a "Start.vi" icon inside the while loop then I get an error "you can do this while the measure is still ongoing".  If I put it out of the loop and then the process only runs once.  I tried to put a loop structure case for restart only if necessary, but this has produced another error which the source escapes me.  Is there a standard way to do this and if so someone can point me in the direction of an example?

    See you soon,.

    I think that in this situation, it would be preferable to use a Pause trigger.  You can use the break to stop the acquisition when the trigger was low and start when the trigger is high.  In this way, served only for the duration of your trigger pulse.  I've attached a screenshot of a VI that illustrates this principle in action.

  • PowerCLI defining politics NTP to "Start and stop with the host" in ESXi 5

    Would appreciate any help in the definition of the strategy NTP on ESXi 5 hosts 'start and stop with the host. My script is currently using the following:

  • Start and stop a loop automatically subtracted at each iteration

    Hello

    I know that there are some topics about this, but I couldn't find any solution, especially because I'm using version 7.1 and cannot open files from new version.

    My problem is the following:

    I need to load a tank of 6 to 10 in the morning, every day for 3 days. The process should start and stop automatically, which means, no funds to start or stop. Start and stop conditions come from time.

    I start with a big loop of 72 iterations, which is 72 hours.

    The tank must start at level 6, whenever he starts.

    After the departure, 1 unit must be subtracted to each iteration. That means, that the tank is level 10, at 06:00 07:00 level 9 and so on. At the end of the day, at 10:00 the fill level is equal to 2.

    The next day, the process must start again and the tank must start at level 6.

    Any suggestions? Thanks in advance.

    Hi Florian.

    Thank you for your message. That solved this problem, but in fact my VI did not work as I wanted.

    I created a new one, with and an external file from 1 to 24, repeat 3 times. Now I got it. Maybe there is a better way to do it, but it works now. Thanks for all the help. I appreciate a lot.

  • Need help with keyframes for start and stop an effect

    I use a mask and blurred for a few seconds. I understand that I must use keyframes to indicate when to start and stop this effect in the video, so that the same area is not trimmed for video full.

    The problem is, I can't find help by correctly setting the keyframes. When I opened the menu keyframes in the effect, it seems that I must together for both the mask took and the blur effect. I did... to start and stop at specific times, but the rest indeed throughout the video, so of course miss me something by using keyframes. The manual to create effects is not useful. I need assistance with keyframes as what I'm doing is clearly not working. Help!

    If the mask does not move that you don't have to set the keyframe. For the blur, click the stopwatch next to 'bluriness' add keyframes as below, the Reds don't blur and blue those maximum blur this fade effect.

  • Free version of ESXi can support for configuration of start and stop virtual machines via vSphere Client?

    I have read and found some documents on ESXi.

    According to the documents, I know that ESXi free version does not support some advanced virtual machine configurations and does not support write to ESXi host permission. But when I download ESXi from vmware.com, I can't find the free version. He will always be a trial of the licensed version edition because I can always do the configuration of start and stop virtual machines via vSphere Client installation. I can also run scripts (lamw) pl in vMA to stop the ESXi host (authorization to write ok?)

    Then I confused. How can I get the really free version of ESXi? Or will the free version after 60 days of evaluation?

    Start/stop above configuration is in vSphere Client via 'Configuration'-> "start/stop VM"-> "Properties"... «-> "Allow the virtual computers start and stop automatically with the system" actions setting and stop virtual machines can be configured to "comments"turn off computer"or"Suspend".» Can any body tell me if it's supported by ESXi free edition?

    Is the free version of vSphere Client too? Because when I use the vSphere Client, he told me that I have 60 days of evaluation. This confused me again. I think that vSphere Client is always free, am I right?

    Any suggestion or advice is much appreciated.  _

    Micky

    Configuration of start and stop virtual machines is available with the free version and licensed, with the free version you would be configured everything via vSphere Client, where as with a licensed version, you can optionally use scripts to configure it and also issue restarts/stops using scripts.

    Second, shutdownHostViaSOAPAPICall.pl for the version licensed and free of ESX (i), this script will work in both free and licensed because it uses direct SOAP calls emulating the vSphere Client communication. Take a look at the documentation for details, but this of course is not supported by VMware.

  • use of an input signal to start and stop screws

    IO have a Vi that must be started and stopped by a signal from a sensor on an automated production line. the problem is that the Vi I created to capture and compare images from a webcam placed on a robotic arm that is used to fasten the screw in part needs to be started and stopped a man using the screw that is "run" buttons located at the top left of the façade of the screws. How can I use an input of probe signal (+ 5 V for 10 ms) to statrt and stop the Vi? The Vi cannot be allowed to run when there is no room for the robotic arm work, it would consume electricity that costs money.

    No program in any language can be started by an external signal.  Some software must be running in order to detect the signal.  If this software is an integrated program running on a microcontroller or a multiprocessor supercomputer it still works the same way.  The power required by the computer is probably low compared to the power consumed by robots and other manufacturing processes.

    As you have described your system, you will need a computer that runs all the time while waiting for something to happen on the Web site, which indicates that a paypal transaction has occurred.  What is different from having a computer running LV with a VI in an idle state?

    If your process needs to be thrifty, you expect better have enough orders that you turn the whole sytem market very often.  The cost of automation of all would be excluded by the income of sproradic.

    It is certainly feasible to have a master computer that controls the power of certain parts of the system that are not needed at all times.  PLCs are used to control the State strong relays or contactors put different subsystems.  Make sure that time is allowed for systems comes on and initialization before you begin production.

    I would focus first on getting the automation of a condition but inactive of working before trying to go to the complete power down and control.  I think you will find that the power process will require sitting in a State of inactivity for some parts of the system while the other parts are being initialized, you will need to do in a State of rest.

  • timestamp as conditions for loops

    Hi, I'm new to LabVIEW. I'm looking for help with my vi, which has some time a loop for waveforms (currently of a simulator) written in a text file. I want to run the conditional loop according to timestamps. I have the timestamp for the start time and the end time and the current time on my front and I wish for my time loop to run continuously until the present time = off time. I'm having a hard time finding an example of code for this operation (simple?), and I would really appreciate help. In the end, I want info stamp time to incorporate in my data file but not the priority now. As you can see my code is a mess right now.

    Use a timer past. Subtract the start time of the end time and the result of wire to the goal time of the timer has elapsed. The timer has elapsed will be in your loop. Boolean 'Elapsed time?' thread to your conditional control of the loop.

  • Records of Vista Media Center starts and stops at the wrong time

    I use Windows Vista Home Premium, SP1 and that you may have noticed that when I schedule recordings for some a particular channel, Media Center starts 2 minutes beforehand and ends 2 minutes in advance.  This affects only shows record from my local affiliate Fox - all other shows for other strings start and stop at the appropriate time.

    I checked the system clock with the start times of the shows and both are correct.  In fact, I saw one day Media Center started to record for a show that did not begin until 08:00 at 19:58 (according to the system time).  I had my TV on at the same time and was able to verify that the program in question had not yet begun, so the flow of the internet was sychned with the dissemination of local transmission.

    It's very frustrating because I miss the end of some shows and cannot always extend registration ends because I'm ordering another channel, the next hour.

    I have the same problem with the FOX network...

    -1 make sure your clock automaticly sets in the internet and update once by pressing the link (which makes that he can see the time server)...

    There are two ways you can go with this:

    -If your departure time is correct, then just go to the Planner and choose the program (or series) you are trying to install, select the recording settings (or adjustment of series) or advanced setting... There is an option to "stop recording" 1 min, 2 min, 3 min, 5 min, until 2 hours after the recording is finished... I have mine set to 5 minutes after, and she fixed it...

    -If the starting time is disabled (as mine is), to enter ERM and manuver to tasks > settings > TV > recorder > recorder defaults

    This is where you define all the flaws of the recorder, find "Start when possible" and "Stop when possible", 4 min value (max allows MCE)... Save and exit, restart the machine too...

    You should be good to go...

    PS, I just read the last sentence in your post, you must only have a tv tuner card in your machine (I have two, and that's the reason why I bought two), so you can always have a problem when recording two different channels (back to back on the same channel should work okay).

  • Black horizontal lines on the LCD screen at a specific time during the start and stop

    Hi, I am currently using a Presario CQ61 Notebook PC.  My problem, as indicated in the title, are black lines on the LCD screen, apparently when the screen is reset or enclose itself turned off during the start and stop only. From the judgment, he produced a split second her stops the hard drive, after that the screen is black. The lines and then quickly disappear. At startup, lines appear after the Windows logo has passed and the screen went from black to start loading the login screen.

    The LCD is in perfect condition, all using the PC. No line, no discoloration, etc.. Nothing extraordinary either. The problem does occur only during these two periods, specifically. I am also unable to note the lines when I'm looking directly at the screen. I have to be standing next to the PC, at an angle.

    Now, I had this PC for a considerable amount of time, however, I never paid much attention to the screen when starting upwards or stop, so this could definitely be something that the laptop has done since I bought it. I also read on similar problems, and it could be an outdated video driver or BIOS.

    I want to just make sure that it is not a major problem. Thank you all!

    Hello

  • Insertion of FLV videos which allow students to start and stop any where

    Hello

    I am inserting the flv videos that students must be able to start and stop anywhere, and when the video gets to the end, the student click on the button NEXT to go to the next slide.

    As long as the student allows playback of the video without interruption, the button NEXT appears at the end.

    The problem I have is that everything works except the button FOLLOWING does not appear at the end of the video, unless the button NEXT is visible for the duration of the video is.

    If the button IS visible all the while that the display of the video, the student is able to skip the video without looking.

    I need the students access to the entire video as part of the course.

    Is this possible?

    Here is what happened.

    I did what you suggested. I also had to insert another Widget playback bar to allow the student to stop the video and restart in a different position. The problem is that the student can stll drag the cursor in the horizontal position at the end of the video, and spend the rest of the video if they want to.

    What I had to do was to show only the playback bar near the end of the tail of the video to allow the student to maniplulate the position of the video if they want to replay one somewhere else. If they don't do anything, the video will automatically switch to the next slide.

    Thanks for the suggestion insert you as a "multi-slide synchronized video" that helped a lot.

  • iOS 10 times to start and stop the music messed up

    I'm running a SE 64 GB iPhone with iOS 10. Many songs from my iTunes library has some moments of power, but after update, they are all mixed. Songs don't start or stop when they're supposed to, or they're going to start and stop at a random time, which is annoying. The same problem was in the beta, causing me to backup on iOS 9. I assumed that this bug would be fixed in the final version. All the solutions in addition to remove and re - download my library?

    Hello Carnage1215,

    Thank you for reaching out to the Community Support from Apple. I understand your music has had some problems and I want to help him. By the sounds of things that your songs start may be delayed or in the middle of the piece, is that correct?

    Before you make too much trouble shooting, it's a good idea to make a backup of your iPhone If you don't have it already. If you do not know how to save your phone from this article will guide you in the process: the backup of your iPhone, iPad and iPod touch

    Once you have made a backup, I would recommend to reset all the settings on your iPhone. This will ensure that all old data of a version of iOS parameter are removed and reset default. This removes all data and applications, photos or contacts, but it removes all of your preferences for the Wi - Fi, Bluetooth, do not disturb, Notifications, general, sounds, contact ID, brightness & paper painted and privacy, then you may need to define these things upwards after this reset.

    Do this please go to settings > general > reset > reset all settings.

    If you always use the same behavior after you restart your phone, please inform the community. We are all here to help.
    Best regards.
