Slow response of the DAQ

My DAQ system includes measuring RTD temperature via a NI9219 module.  The usual analog to (NI9201), analog out (NI9264), digital in, digital out (NI9401) work fine and run properly with a single software timed while loop 20 Ms per iteration.  When I add entries temperature that the loop slows down at the rate of 2 Hz of the NI9219 - fine for measures of temperature but too slow for the user interface and the rest of the system.  How can I keep the loop running and don't update the temperature data when the NI9219 ends?

Thanks to each of you for your help.  Lynn, your answer got me on the right track, but I don't need the design / the response of consumers.  What I needed, it is three while loops.  One for slow sensors (NI9219), one for user interface and fast sensors and a third in both.  Now LabVIEW begins the slow acquission, and then allows you to run the fastest acquission.  I have a lot of cleaning up to do, but that's the easy part.

Once again, thank you to you two.

  • Slow response from the keys

    Hello

    some time after the start of my laptop, I'm starting to get a slow response by pressing and holding a button. Which means that, when I release the key the character continue tp appear about 2 seconds more! So, for example if I use the arrow keys, that I do not in the exact spot I need because the cursor will continue several characters to come.

  • Slow response from the DPM Touch Interactive applications

    Hello

    In our premises of the Subscriber, we deployed a solution we have developed as a tactile interactive application using a 3rd party Content Management System. The content of the application is pushed to the DPM and stored locally. This app is more graphic, and there is no video no is involved. The size of the content is aroun 105MO. We use 3 m touchscreen.

    The application is designed so that when the user clicks on tabs, it goes to that specific tab content. The question here is, when the user clicks/keys on the screen of the tab, it takes more time to react, which means it takes longer to access this particular screen. So I'm not sure how reduce response time.

    We use Cisco (OEMed) 32 inch screen with a resolution in 1366 x 768 LCD, what is said in the native resolution. We use the HDMI to connect to the DPM on the LCD screen.

    Please let me know how to increase the speed of the interactive application.

    JK,


    The first thing to do is to reduce the question of time 'response' to a

    the driver for 3 m touch OR the application itself.


    You can use another touch application (1 or more) for a reference

    on the response of the tactile response.  If all the applications meet

    the touch with the same delay so the problem "may" be with the

    3 m touch driver and may need some improvement and refinement.

    If the other touch applications are faster to respond then your App "Touch".

    at issue, the US is facing an application problem.


    Is a common symptom seen with performance and custom applications

    because developers create applications and workstations with high

    fast video cards and processors.  Therefore, what is acceptable

    performance on the workstation does not to the slower

    DMP.

  • Slow response of the Adobe Digital Publishing team

    Response of the Adobe Digital Publishing team, trying to slow down the contact form at the beginning last week and no reply, I noticed from the USA has a phone number, but the Australia has only a form page. I have 2 books of kitchen I want to create applications for, it is better to with Adobe DPS or is it only for large companies now.

  • VCS slow response in the GUI after X7.1 upgraded

    We recentlty improved our VCS to X7.1 and see the GUI response is very slow.

    We have the box integrated with LDAP for authentication for the admin user. We tried using the box with both local and remote authentication.

    But still the connection time takes about 3 minutes.

    Should check us here to continue further on that. Pls suggest.

    Reboot option will be the last resort.

    I had the same problem with one of my VCS highways after the implementation of LDAP authentication on 7.1.

    I have 6 VCS commands and 4 highways all on the same version of the software and the integration of LDAP in the same environment video and just a box was not happy.

    Cisco suggested I try to factory reset the box and reconfigure but which did not help.

    I eventually found a number of RMA.

  • Slow response from the user interface with acquisition of data of type long time

    Hi all

    I have a question to ask more out of curiosity than necessity right now. I've built a program that acquires data from the accelerometer and the Treaty in a number of ways: filtering, FFT, FRFS, things like that, but the answer of the UI is still slow, because I need a resolution of frequency of 0.2 Hz for my data domain, which means that the sample acquisition time is 5s and all this awaits before execution.

    My question is this: is there a way to completely isolate the user interface of data acquisition so that it responds immediately?

    I tried a design model of producer consumer with queues, but found everything to be always waiting for samples to be taken. Maybe it was exactly as I did.

    Thank you

    Phil

    If you need to sample for 5 seconds in order to have enough data to analyze, so unless you can "predict the future" and "knowing" the five seconds of data, simply wait for the data that arrives.  Using parallel loops of producer-consumer will allow data acquisition to proceed (for the next 5 seconds of data) while you do the analysis, but you still have to wait for the data to be analyzed.

    Note that the previous paragraph assumes you are collecting data in 5 seconds 'chunks' and analyze each "chunk" (independent) on arrival.  You could also do something like having a "second 5 sliding window" which moves, say, a second at a time, giving your FFT a finer resolution of 'time' (at the expense of their independence).  This would be a (slight) change in your loop of producer (you want to taste in 1 second pieces, accumulate 5 these pieces) and the consumption loop (start analyzing, spewing a FFT every second, while replacing the older "chunk" with the most recent - a queue with loss can do for you).

    Hello Bryan,

    Thanks for posting your query in Microsoft Community Forum.

    1. It was working fine before? If YES, then you did important equipment or modifications to the software on the computer before this problem?
    2. What is the brand and model of your system?

    The slowness of your system may be due to various reasons, including viral infections, interventions of third-party software or a hardware problem with the mouse or the keyboard. So, to refine the diagnosis, I would suggest trying the following steps and check if the problem persists.

    Method 1:

    Step 1: Try to start your system in a State of services necessary to the operation and a minimum set of drivers enabled, called Safe Mode.
    Start your computer in safe mode http://Windows.Microsoft.com/en-in/Windows/Start-computer-safe-mode#start-computer-safe-mode=Windows-7

    Step 2: If the system works fine in safe mode, try to clean the system startup:

    How to perform a clean boot in Windows

    http://support.Microsoft.com/kb/929135

    Note: See "How to reset the computer to start normally after a boot minimum troubleshooting" to reset the computer to start as usual after a repair.

    Method 2:

    The issue may be due to an infection by the virus. So, you can also run the Microsoft Safety Scanner to make sure that the computer is free of infections:
    http://www.Microsoft.com/security/scanner/en-us/default.aspx

    Note:
    The Microsoft Safety Scanner ends 10 days after being downloaded. To restart a scan with the latest definitions of anti-malware, download and run the Microsoft Safety Scanner again.
    The data files that are infected must be cleaned only by removing the file completely, which means that there is a risk of data loss.

    For more information, see:

    Hope this information is useful. If the problem still persists, please post back for further assistance, we will be happy to help you.

  • How can I fix the very slow response after the wake up the computer from sleep mode?

    Never had this problem until a few days ago. Using Windows 7. I want to use the "sleep mode" whenever I leave my office (be it for a few minutes or several hours). Always came back just as I left it (tabs, work-in-progress, etc.) until recently. If I reboot, everything of fine, up to what I use mode "time" again. So painful.

    Thanks for the tip. I disabled the accelerator according to your link and suggestions and the problem seems to have been resolved, at least for now!

  • slow response after the restart of the host

    Is this normal with the VC 2.5 Update Manager after the updates were installed and the host is restarted, it takes forever for the reclamation fill. For example I put a ping goes to the host, and after that the host has restarted, he comes to have 7 minutes for sanitation, task to understand it can complete sanitation.

    Its always been ' not a problem as such "but an observation that the illustrious host offline for awhile while the reboot and then comes back online, then the reclamation task is just there for a few minutes does not turn.

    Like I said this isn't a problem, but I was just wondering if this was normal?

  • Laptop HP Pavillion DV7 - HDD1 real slow response

    I have a laptop HP DV72185dx of 2.6 years. It has two 500 GB HARD drive. The HDD1 is having very slow response of the week times last 1. I did a HARD drive test in BIOS menu. For HDD1 the quick test stopped at 17% with an error code of 303. Then he went into full test and stopped at 4% with an error code of 305. INTELLIGENT test succeeded. HDD2 passed all three tests OK. Pls advise if it needs a replacement HARD drive. If so, what type of HARD drive me I need to buy. Also is there a program that can ghost HDD1 data to the new drive HARD (I don't want to miss this chance on some software programs that are already installed.

    Note: I have Win 7 Home Premium (64-bit). I guess that my laptop warranty is over.

    Hello

    As you mentioned that the error code 303 said that the hard drive is down on the unit you will need to replace the hard drive. Please replace the hard drive the same capacity & if possible the same company as it will be easy for you if you enable active RAID please go through the below web link.

  • Performance of the hard drive, runs at 30% all the time; slow response

    Pavilion Slimline works 30% all the time, slow at times, all the time. Run the Task Manager, identified all of the questions.

    Defragmentation, historical, navigation can be run. Registry cleaner also run.

    Still slow responses,

    Suspect still running games, must stop them, as well as other unnecessary programs.

    Any suggestions, useful, believe, this will solve the problem and improve poor performance.

    Thank you for the comprehensive answer. If the speed is the main problem now, theoretically, upgrading the hard drive would be able to increase the speed up to a point. Of course, this would impact speed of normal programs, programs on the web, etc. I also carefully read the document provided Red Rose, and although it is informative, I don't know about most in this paper has been tried.

    Regarding the age of the laptop, age obviously decreases the computer's full performance, and you have little control over this, unless you buy another computer.

    I have an idea of how research and troubleshooting have achieved you, but it is only an idea. I'll link some documents with information that you may or may not be useful:

  • Someone knows the extremely slow response and delay with "not responding" on more complex web pages after installing updates on Friday?

    Since the installation of 16 Nov received security patches I've known really slow response with Internet Explorer; 2 minutes between web pages on my WIN7 Pro PC and not much better on my VISTA Business PC.  I get expired on complex web pages the context comes up with "program addresses not" or the pop-up at the bottom of the screen asking me to do it again.  The problem is not limited to Internet Explorer, but also prevents Safari to come.   I tried to reinstall WIN7 Pro, but the problem remains.  I'm also not able to run You Tube or other videos.  There is no download or updated or running Belarc Advisor Windows installation problems.  While the problem occurs with Yahoo Mail, it is not an impact send/receive in Outlook.  Does not appear to impact, nothing other than browsing the web.

    Hi ephd,.

    Thanks for posting in Microsoft Communities. The problem description, I understand that the internet works slowly. Provide the following information:

    ·         Have updates you installed?

    ·         You get the error message?

    Follow these methods.

    Method 1: Temporarily disable the security software .

    Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you do not disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network during the time that your antivirus software is disabled, your computer is vulnerable to attacks.

    Method 2: Follow these steps:

    Step 1: Start the computer in safe mode with network and check.

    Startup options (including safe mode)

    Step 2: If the problem does not persist in safe mode with networking, perform a clean boot to see if there is a software conflict as the clean boot helps eliminate software conflicts.

    Note: After completing the steps in the clean boot troubleshooting, follow the link step 7 to return the computer to a Normal startupmode.

    Method 3: Follow the steps in the article.

  • The response of the mouse becomes slow and I get the low battery warning

    Original title: Use the Microsoft Wireless Multimedia Keyboard 1.1 model 1014.  Recently, I had replace the batteries in the mouse at least once a week.  Is there a solution?

    The response of the mouse becomes slow and I get the low battery warning.  Until this started happening batteries have been change less than a month.

    Hello

    1. What is the brand of mouse and the model?

    2 have you ever done any recent software or changes to the hardware to the computer?

    If you use the Microsoft mouse, I suggest you follow these methods:

    Troubleshoot a wireless mouse that does not correctly:
    http://support.Microsoft.com/kb/321122

    Troubleshoot the incidents of the response to the mouse or wireless keyboard:
    http://support.Microsoft.com/kb/838398

    Use the following tips to get more life on the batteries in the keyboard and mouse:

    a. use the mouse on a surface of clear color. With the help of the mouse above a black surface can deplete the battery at a faster pace.

    b. do not use the mouse on a glass surface.

    c. when replacing the batteries, use alkaline batteries. Other types, may not last as long.

    d. when wireless devices are not in use, store them near the computer.

    I hope this helps!
