The use of registers at offset in a while loop that never loop

Here's a picture of 'syslog_Device function Engine.vi. This isn't really a question specifically about this vi, but rather a technique I see here.

First thing I noticed, it was a while loop always outputs, never loops. And shift registers. This serves for the VI can retain values between calls, almost like what I consider a local variable which are persistent between function calls in another language? It is an interesting way to accomplish what I have not looked at.

Please tell me if I'm missing what is happening here.

It is a driving force.

It's a code construct that allows you to encapsulate data and features that are available in multiple threads.

The nugget I linked above explains their operation the theory behind them and follow-up discussions in discussion on how to exploit them.

Good questin incidentally!

  • position in the property node is not updated in another while loop

    Hello

    I have a structure of the event in a while loop and I have a chart with 2 sliders on it. the chart is in the loop outside the structure of the event and it becomes a wave form when an event occurs.

    in a separate loop, I have 2 cursors cursor position property. I subtracted to get their distance. but when I move the sliders on the chart which is in the first, while the loop doesnot change the values given by the property nodes in the second loop

    is this something related to the structure of the event? don't needs real graphic to be updated all the time or is it ok if she becomes a waveform only on an event

    can someone please help

    Thanks in advance...

    The value of the variable "Stop 2"is in memory still "True" so on that a second (and resulting) running that your upper loop always ends after the first run.

    The display of "stop 2' LED is to be reset when you press the button"Get the waveform". making the False value.

    So reset the variable button after finishing two loops or before starting the two while loops.

  • The use of VS2015 to create a C++ Windows Service that works reliably with Windows 7 and 8 and 10

    We have created services windows (log events in the event viewer) using VS6.0 and noticed that they were not reliable running on Windows 7 (and beyond). They stopped unexpectedly after startup and so on.

    We have VS2005, 2010 for the development of Qt and never looked in services portage. We have to bought VS2015 and found that C++ Windows Service models have not been provided for VS 2010. We have inherited code which must remain C++ (c# conversion is not an option for us). Someone out there who has created a Service from Windows C++ for recent versions of OS? It installs with InstallUtil.exe as the most recent services c#?

    This issue is beyond the scope of this site (for consumers) and to be sure, you get the best (and fastest) reply, we have to ask either on Technet (for IT Pro) or MSDN (for developers)

  • Update of the indicators of the tank (by sending a command in a while loop)

    Hello

    I'm slowly get a little more familiar with LabView and feel enough confidence to the code for an ISCO pump (model 100dx).

    My pump has two needles, and I would like to display the amount of liquid contained in these pumps - without interruption.

  • in what version of labview the ' stop if true ' condition become available for while loops?

    The answer to this question would mainly just my own curiosity, although it would also help to explain why some LabVIEW programs I have others that have been written in previous versions have strange as constructions invert a Boolean condition before it is wired to the 'continue if true' (when obviously they could have just wired the condition directly to a ' stop if true ').

    Not sure 100% but he could LV 6. I 6i on a virtual machine and it's there, and I don't remember having this feature available in LabVIEW 5.

  • or HOW the signal to timer front door stop in while loop?

    Good afternoon

    Could someone please help. I have a project that is very basic. It performs replication of the mastermind game in labview2009 VI. I have managed to do work, but as soon as all the conditions are true my last or door sends the signal for the moment stop button loop.

    In other words, there is no time for my 'congratulations chain' to show before the game resets. What I have to do is to put a timer between the final or gate and my stop button, but all the methods I've tried don't seem to work as the data types do not match.

    Please please please a little help

  • How to make a graphic inside a while loop to maintain the previous values

    At first I tried to use a the VI Express XY graphics to create a track of points.  However, the chart is a trace linear between the first point in the new line and the last point of the previous line.  It then creates the new line as you wish.

    I tried to use a loop with group a cluster for the chart, but the chart resets the plot at each iteration (as expected) and I can't find a way to maintain the previous data.  I tried using shift registers, but was unable to find a way to do it, and I tried also the cluster of a painting company, but can not find a way to make the cluster to a 1 d of a cluster of 2 elements array.

    One option is to have is to find a way to maintain the previous data, but the preferred option is to create a new path to each iteration to see the color change for each new parcel.

    I take stabbed it because I don't know exactly what you want. But I think that's what I've shown here. You must use a shift on your outside register while loop, as I showed. Your image where you tried to use a shift register shows a misunderstanding of the shift registers and how well they work, then I'd take a peek at these tutorials.

  • I have problems with of the Subvi after the use of customized device model

    I used to start my machine personalized customized device model and I got success in the deployment until I started to do more complicated the Subvi.   I am currently trying to convert low FPGA and high ticks to the duty cycle, but for some reason when I add it to the RT VI "Data read of HW" driver, it seems to cause a downtime... ideas? Is a circuit agree? I have added a time delay but I am still having problems. It is a device online, so I'm suspicious of it hogging resources, but am not sure.

    Attached images are meant to be read like this:

    1. the case of the RT pilot ReadDataFromHW

    2. it's the Subvi calling ToDutyCycle SIMStimPWMSubVI

    3 ShiftRegister.PNG is inside the Subvi.

    As a robotician I celebrate early and often (usually by a failure or two...), but it seems that the answer was to transform fundamentally the While loop for a loop with a count of 1 and then remove the additional elements to ensure that each shift register has that one and then right click on the shift registers and convert at the Feedback node...
    I was able to deploy to VeriStand as a custom device and it runs and calculates the factor of use with no problems. WOOHOO! Where - what is celebrate button!

  • Using shift registers global verses

    I'm new to 2009.  Our last update was 7.1.  I'm upgrading our laboratory SW and using events.  EVENT 1: is used to display the data in a text file in a table "data set".  EVENT 2: using to option button and the table "Data set", the user selects the data column to use for the test that is displayed in a table «Points de Test»  EVENT 3: If the user changes the data in the table "set of data', 'Points of Test' test point table is the update.  I use local variables for 'Set data', 'Points of Test' and I was going to use other settings as well (radio button, etc.).  I also think about using a shift register to realize that the same information.  I used shift registers in the past and they can be annoying, but I also understand that you should stay away from variables.  Please pass along an Advisor on the use of local variables shift verse records.  THANKS in advance!

    I don't know what you defined as 'EVENT 1' to '3', but they seem to be quite the case.

    The use of shift registers sounds messy, but they are much better than local Variables If you parallel threads past in your code.

    Clean the threads between the shift registers is to use clusters.

    People of the country appear more clean, until they 'byte' you in the... code...

    EDIT: "they are much better than local Variables If you parallel threads going on in your code" I have to explain... If you have parallel code that uses Variables to local variables as this may lead to a race or conditions...

  • What is the best way to correct the registry errors without the use of a registry cleaner in XP?

    I am sorry to raise this issue that so many people who have asked me.  I read pages and pages of discussions on the MS forum on this subject, and without exception, all the experts said Microsoft registry cleaners are completely unnecessary and that junk in the registers has no performance impact at all.  Instead, they say, to do x, y and z.  I am running Windows XP on my desk for five years, and gradually, he got so slow it's almost unbearable.  It takes 10-15 minutes just to start, and sometimes it takes 2 minutes or more just to open a window of browser (IE8) or go to the previous page by using the arrow to the left.  Before you tell me all the things it could be, please let me say that:

    1. my PC has not always been this slow!  It is getting worse.

    2. all my Windows software is up to date.  I have automatic updates on.

    3. I have a lot of disk space, almost 75% of free space on a hard drive of 80 GB.

    4. my PC is free of viruses, spyware and Trojans.  I have McAfee antivirus running and I also sometimes run Malwarebytes and Trojan Killer, because they always find things that don't have McAfee.

    5. I defragment my hard drive on a regular basis.

    6. I regularly delete all my temporary files by using the Windows Disk Cleanup utility.

    7. I have very little, if any "Add-ons".  No toolbar Yahoo or Google (or Bing!).

    8. I removed nearly every program that I start, so that they are not running in the background.

    9. I uninstalled all the programs that I don't use.

    However, I still have a slow ever-more computer.  Sometimes, when I see ads on TV to increase the speed of my PC, I download the 'free' software, and they claim to find hundreds or thousands of "registry errors.  When I look at the newspapers, I see many entries in registry for 'Netscape' and 'Google Earth', which I uninstalled years ago, as well as entries for the videos that I downloaded, seen once, and deleted a long time ago.

    So, what's the problem?  If it's not related to my registry (which Trojan Killer says has more 6 000 entries!), what else could be?  I would appreciate greatly any advice you can give, because there are dozens of companies on their touting their registry cleaners and the uninstall (for a price) programs, and after reading reviews of the MS MVPs, I'm skeptical of their claims.  Thank you.  :)

    I can't disagree with a lot of things have already been said.

    I'm willing to accept that your machine does actually takes 10 to 15 minutes on the clock. It's completely absurd.

    Some people call your "Windows Rot" problem. Becomes just the slower windows over time. It is a collection of things that are happening in the background. Yes I believe that the register contributes. Using a registry cleaner is not a "magic" solution But it can help a little.

    The PC care program/process you described is above average.  I suggest you add CCleaner. Disk Cleanup is not bad, CCleaner is better, cleaning of other stuff which does not resemble the DC. It won't be a significant difference because disk space is not your problem, but it will help a little.

    'Play' with the registry is VERY risky. If you decide to go ahead, I would say that first make you a copy of the full image backup using a utility that can be started and run from a CD/DVD. Just in case the registry cleaner breaks of your machine.

    Registry cleaners is that they take a "best estimate" to what is no longer necessary. Sometimes they think wrong. And each vacuum cleaner will clean slightly different sets of places.  If the tool does not provide a way to back up the registry before you start cleaning, do not use it. He is not careful enough.

    If vacuuming offer 'levels' of cleaning, enjoy. Open for more aggressive cleaning, with resetting and long series of normal use between cleanings.

    You are looking for a tool which also makes registry "defragmentation". The registry is a database that get disorganized by additions and deletions. Defragmentation will be re - organize and get rid of a 'lost' space, making it the smallest file, afterwards faster to read.  It is not something you need to do frequently, but since you've never done it in 5 years, it would help, after cleaning registry.

    Another place to find CPU and RAM wasted resources is Windows Services. These are small programs that start at boot time. They run in the background and provide support services to all applications or specific applications.  Many applications services are running even though you don't really need them. You can find information on which you can set by Googling for 'Windows XP hardening'. There are a lot of sites with good information. They call it hardening because by disabling unnecessary stuff, you leave less possible openings for the "bad guys" to the attack.

    Ultimately, I think your best bet will simply bite the bullet and re - install windows and all your applications. It's the best way to restore your computer to almost any performance fees factory. (It is not exactly factory fresh because you need to add a ton of Windows updates).

    Before you re-install, do copy image 1 or more full backups. At least one must be done using a tool that will easily allow you to extract the files. You data backup files separately to make it easier to restore the reinstallation. IE, copy it to a USB key.

    Many "experts" actually expect to, and do, re - install windows every 6-12 months!  I think it's a bit exaggerated, but they swear by it.

    Once you do your re - install, create a copy of the magnified image
    Install a firewall application (before the windows updates)
    Once you do all updates of windows, create a copy of the magnified image
    After that you re-install all your apps, create another copy of the complete picture.

    In this way, in the future, you have more current points to restore your computer to. It will reduce the time you spend to get back to the current configuration.

    On a 5 year old XP machine, you have probably 512 MB - 1 GB of RAM. You might also consider taking in the shop (or DIY) and bump the RAM up to at least 2 GB or better still max out.  The current versions of the applications use much more memory than they did 5 years ago. Even XP will be since he has been seriously corrected since then.

  • "No cell coverage" not listed in the use of the battery

    During the audit of the use of the battery parameters, on an iPad 2 Air, WiFi and cellular, upgrade 10.0.2, 'No cell coverage' is listed and uses a lot of battery percentage. This never happened since the purchase of the iPad two years ago. I've recently updated to iOS 10.0.2 and T-Mobile as the cellular carrier. This occurs when the two Wi - Fi AND cellular data are turned off. I barely use the cell service as it is, first of all just use wifi, and I never leave the cellular data connection on when you do not. I noticed a few days ago a T-Mobile "Carrier Update" has been pushed to the iPad. Someone else with the same situation?

    Hi there, stumped127! Thank you for using communities of support from Apple!

    Use of your iPad 2 Air indicates that it is looking for service even if you have data Wi - Fi and cell phone turned off after update to iOS 10.0.2. Given that mobile data is off, it shouldn't have an impact on the battery and I will be happy to help you with this. Be sure to test after each numbered step.

    How to back up your iPhone, iPad and iPod touch --before troubleshooting a device, I always recommend a fresh backup. It is preferable "to have" one to the 'need' to a backup.

    1. forcing a nearby app on your iPhone, iPad or iPod touch - first, quit all running applications, and then restart your iPhone, iPad or iPod touch - never underestimate the power of a good restart.

    2. reset the iPad settings - do not forget to write your networks, Wi-Fi/passwords before you start. On your iPad, go to settings > general > reset > reset all settings. This step returns your iPad to factory default settings. Test and if that solves the problem, use your backup to restore your settings.

    Take care!

  • Sierra Messages App is forcing the use of the discrete GPU

    Since the update of my mid 2015 15 "MacBook Pro to Sierra, Messages.app requires the use of the discrete GPU and kill my battery time.

    All the world fell on this and if so, have you found a solution?

    Here, even with a MacBook Pro in early 2011... problem seems to be based on the new 'features messages"that you can use in iOS 10.

    From messages app, the internal GPU is used until I get a message with one of these new features to messages. Then the GPU will switch to the discrete GPU AMD and continues to work with him until I left messages app.
