data collection ignores every 0.5 seconds

Hello

I use a NI9205 to collect four different load values outputs plus a NI9236 for several values of deformation using the attached VI. For some reason, during check-in for several more seconds, I noticed that the charges on the 9205 jump a single data point every 0.5 seconds. I have a frequency of 100 or 200 points per second recording, but the question is when I try to plot these data. The following values are moving in where gaps should be, so the end of 3 executed same second, the values of load and strain are off by 6 hundredths of a second. When I export the data to an excel file, load values cascade not upward, but variances are always a problem, because they are visible on the drawn line graphs. I know that's not a problem with data acquisition, because I ran a similar program in DasyLab who had no problem jumping of data, but it only happens with the 9205 (not the 9236), so I'm confused here.

Any help would be appreciated!

hhart, your loop of consumers is directly dependent on your loop producer via the reference queue and cluster of error. In other words, that they will not work in parallel, since the consumer loop will wait for the loop of producer to stop before handling the queue.

Here's how the producer/consumer with a queue should look like:

Programming LabVIEW is based entirely on the data flow and parallelism. It is incredibly powerful and has led to its success over the years (coupled with graphical programming), but is usually one of the first things the new developers stumble on. This is a simple resource to familiarize themselves with its functioning. The function to highlight execution is a great way to watch how your application uses data streams.

    You must write a custom for this JavaScript calculation because you cannot add a number any date. Also the date strings are not just a number, even if we can convert a given date in a number for that date that represents the time form a date date (Epoch). Witn this value, we can achieve them all kinds of date calculations and collect a little information about the date. JavaScirpt uses midnight on January 1, 1970 UTC for starting point or the date of the time. Its value is zero, and every millisecond increases the value of 1. When a date string is converted to the date object JavaScirpt we have access to many properties of the date and can use several methods to extract information or adjust the date object.

    Field 1 is in the format "Date" with a format of "mm/dd/yy".

  • How can I write only 1 sample every 0.5 second to my excel sheet

    It's the VI I work on... everything works fine but I have too many samples per second on my excel file... I just need 1 sample every 0.5 seconds. How can I solve this problem?

    Thank you very much

    The default values on the DAQ Assistant 100 samples acquired at 1 kHz, then each cycle you get 100 data points.  If you want only 2 points to a second and avoiding the is acceptable, could I plug "1" on the number of samples on the DAQ Assistant (or right-click and select properties to configure the node) and use a software or a timed loop delay in the loop like "wait until the next multiple of ms.  Alternatively, you can use screws more advanced such as 'DAQmx read' to get the desired behavior.  Remember that the data acquisition will be back as soon as he gets the data that you invited to capture, so you'll probably need something to keep periodic things between cycles of the loop unless you want to move to continuous hw timed operation of data acquisition.

  • How to set the time of data collection for information Publisher report

    Hello everyone,

    So, I'm trying to set up a report, which contains some information of tablespace. The report must be sent to my e-mail account around 07:00 every day, so I have an overview if we run into a few problems with some full tablespaces. the report and mail notification works well but my only problem is, the data are not updated. There is a comment under each data table in my report which said that the data had been updated on 8 to 13 hours ago according to the target database. is there a way I can trigger the update of data report on a specific time? So I can update the data before you run the report job every morning around 07:00? I'm totally noob, so I hope someone can help me, I tried to google it but I couldn't find anything useful.

    Unfortunately, there is really no good way to 'schedule' collection for this because it is perceived with a dozen of other data points and likely to cause problems.   What you could do, is create a metric custom extension with query data file you need (simple Dungeon it do not go beyond what you really need to prevent performance problems), deploy the metric on all target databases, then disable collection of gui (metrics and collection parameters) and cron the collection to run at a period determined using emctl control agent runCollection : .   You can then create a report about the data collected in mgmt$ metric_current.

  • Will be my changes Lightroom RAW and usable by the Adobe programs no data collections?

    Hello.  I have a few questions that I was not able to specify, so I hope someone out there can help me out.  I learned about Adobe Lightroom 3, and I have a few questions.  Basically, I understand how the program works, but I need to know the following.

    -First question: my montages (in Lightroom) to my images (changes of wb, color, contrast, etc) on my files DNG or NAVE & XMP can be opened and edited by programs that are not by Adobe?  I know that I can export the RAW files to JPEG, TIFF or PNG, but the RAW of Lightroom edited files can be used later by a non Adobe like Bibble software?

    -Second issue: my Lightroom database (matadata, keywords, rankings, catalogue, collections, etc.) can be used by programs other than those by Adobe, such as Bibble?

    The reason why I ask is to clarify if my Lightroom RAW file edits and data collections will be nothing outside the universe of Adobe?

    Thanks for any help you might be able to shine on the question.  I appreciate it.

    Will,

    1 n ° If another program can read the changes in lightroom and apply them exactly like lightroom, this program will be lightroom. There is no canonical target for a raw file rendering. Each rendition is based on what some thought better developers and is purely a matter of opinion. And no no adobe program attempts even to read data from change in lightroom.

    2 No. kind of. I think metadata, such as keywords, IPTC and rankings stuff are standardized and can be read by most of the things. Collections, such as virtual copies are held only in the catalog.

    That said, Lightroom does as good raw files work rendered as anything out there, and personally, I don't see any reason I would like the answer to any of these questions to be Yes.

  • Re: Satellite L500 - fan power switch every 5-10 seconds

    Hello

    I have a new Toshiba satellite L500 1XX with i3 and I installed the 32 bit OS.
    Starting from the first start, the fan is acting strange every 5-10 seconds it started working for 5-10 seconds then stops for 5 to 10 seconds, then again, who's going all the time even if the flurry of the laptop stand out with something.
    I think that something is wrong, but was not able to find it. Please I need help
    Thank you

    Hello

    That's ok with your laptop. My satellite that a500 is also like that, even if I surf the Internet, watch movie and CPU shows only 5%. I don't play all the games. It didn't because of the dust because I clean it regularly, installed all the drivers, BIOS updated. The only way to make it quieter to run the fan at a constant speed as 54%, I simply load the CPU with some applications that maintains fan runs almost every time and not boring perceptible noise.
    You can play with the power settings in the power management, but in my case it does not help. And do not decide yet upgrade the Bios, it don't improve you but can kill your knees so wrong.

    I just bought Need For Speed - Pro Street and installed on my computer. I can't play the game, without the screen freezes shortly every 2-3 seconds.
    It seems that there is not enough power visually, but with 2 x 8600M GT in SLI? Will not take the game run smooth without delay?
    I have all the settings at low temperature and/or offshore, trying to see if that would solve the problem - but no.

    The menus and the intro works very well, but when driving cars in the game, it starts to lag.
    I've updated to latest drivers, but which did not help either.
    My OS is Windows Vista Home Premium, and my memory is 2 GB.

  • VIDEOS OF BUFFER EVERY 10-15 SECONDS

I tried their first stamp with a PAUSE the video and wait 30 to 45 seconds, I tried everything that was suggested, but it continues in buffer. The only way I can watch a video until the end, is to leave this buffer for the execution of all, and THEN, sometimes, it works. But this is RIDICULOUS.

    When I got to my HP Windows 7, videos do NOT put in the buffer. Now they consistantly buffer and he drives me up a wall. I don't have the time to let all buffers videos for execution of all! Someone at - it OTHER ideas, or I come to my Windows XP and Dell computer? I need help.

    Jerry, welcome to the forum.

    When a help request, you must always include the brand / model of the computer or the monitor. This information is necessary for us to review the specifications for them.

    Have you tried to lower the resolution (720 p to 360 p) videos to see if that helps?  Windows XP takes much less power, and is much less complex than Win7.  This can make a difference how to run programs and videos.

  • WJA - has no alerts - inaccuracies of data collection

    I've been running Web Jetadmin v10.2.7491B on a Server 2003 during approximately 3 years. There are 120 managed printers consisting of 9 different models.

    Question #1

    Initially, I got alerts configured on all printers that would send an email when a consumable fell below 3%. It worked very relibly for the first year. Over time, a growing number of printers stopped to send reports, until finally only a handful sent alerts. I never found the cause of this problem.

    Question #2

    Alerts being broken, I set up a collection of data daily for all printers and a csv morning emailed report. I then sort data in percentage of consumable remaining and replace those 1% or less. Recently, reports have stopped 3 models on 9 specific consumables percentages in daily reports. This problem seems to be with an update of the firmware that I pushed to all printers. The console does HOSTS shows specific information for individual printers when they are selected.

    Steps taken to solve #2

    Printers have been removed from all groups from the Collection of data from reports and then added. This has not solved the problem. Printers were originally added individually to a data collection, but I've set up a group policy that automatically adds a printer to the collection of data. 6 models of printers are still accurate percentages, but not the models 4345, 4730 and 5035.

    Is there a file database that I can delete that forces a rebuild of the collection of data for all printers? Is it possible that the new firmware for the 3 models listed has a bug which prevents update data?
