• Synchronization of two inputs frequency meter with several analog inputs

  Hi all

  I'm relatively new to LabVIEW and I'm trying to collect data from multiple sources with calendar sync on the acquisition, but I can't understand. My problem is that I have two inputs frequency meter, an optical tachometer reading one pulse per revolution and a max flow meter machines with a 12000 k coefficient. I can't find a way to synchronize the calendar with my multiple analog inputs. I tried to first get the speedometer to synchronize with the analog inputs following the example linked here. (https://decibel.ni.com/content/docs/DOC-10785) So far every time I run it I get an error on the DAQmx read timeout or an error "several sample clock pulses have been detected" (see image).  It seems if I slow the way to down to say 10 hz and make sampling rate ensure that the tachometer signal is more than 800-1000 rpm (13-17 Hz) before starting the VI then the program will run without error until the ROTATION speed is below this threshold, then the "sample Multiple clock pulses" error occurs.  The code is attached below.

  Does anyone know of a better way to synchronize the entries of frequency of the counter with analog inputs?  I would like to have a VI that can display 0 RPM (and possibly 0 flow as well, but I think I need to understand the timing of a meter before I have add another, because it seems that I can't have two counters to the same task). Any help on this would be greatly appreciated.

  I know the error requires to restart the task at least (this particular error puts the material in a State that cannot be recovered from during execution of the task - I've been down this road before) but I'm surprised that you would have to delete and re-create the task altogether.  And then I had to do this to workaround other questions in the past.  It is awkward and should be considered a bug, if this is indeed the behavior.

  Honestly, regardless of this bug, the way the material dealing with the situation of several sample clock edges makes measures of sampling frequency clocked essentially unusable for purposes of synchronization (in my opinion anyway) If you encounter a more slow than your sample clock rate.  You are supposed to be "synchronization" of the measure, but it really no longer applies if you have to restart the task over and over again (if you must delete it or not).

  Workarounds can get kind of creation (which isn't really a good thing).  For example, you can configure a measure of implicit frequency to keep a buffer of frequencies and use a leader board task (source is the frequency signal, sample clock is the sample clock HAVE) to establish a correlation between the index of your buffer of frequency for singing HAVE sample clock.

• How to synchronize two chassis

  Dear all,

  I want to synchronize two chassis, chassis first has RFSG 5673E (S) and other chassis a DAMA (S) 5663E, they are connected via MXI, is there anyone who has this experience and can support me to apply it. I know that he used NI-Tclk to synchronize in a single chassis and there is another kit of tools for mult chasis, but I have no idea on how to use it!  Thanks in advance

  Best regards

  So I did a little research and to allow you to synchronize the two chassis together you must use a map of timing and synchronization in each frame so that you can share Tclk. This is for several reasons: first of all, as well as terminals IN CLK and CLK OUT, several PFI lines are required for the export of various signals used by T - CLK (i.e. Start, Stop and Sync triggers). In addition, the map of timing and synchronization is also necessary to replace clock background basket of 10 MHz, on the chassis of the slave with the master clock. It is essential for the two hunts reference the same clock synchronization. In addition, using a more stable clock source, as provided for in the calendar and map of synchronization, improve synchronization significantly.

  From there, a chassis are sync'd up, TCLKing la 5665 and 5673E should be simple enough. It should be simply a matter of configuration tasks the DAA and RFSG, with a single trigger configured, before feeding the two tasks of the TCLK vi. Here is an example for you to study what explains this:

  Apple has not renewed the contract with Google to access Google servers.

  If the old version of iPhoto, which are still using Google's servers for the cards and places are either crashing or hanging.  Places are only work in iPhoto 9.5.1 or newer, who use places of Apple servers.

  There is more support for iPhoto from Apple.  You must update iPhoto 9.5.1 with the Mavericks. It would work well, only it is no longer buying this update to Apple.

  Perhaps the reason for the problem of synchronization is the problem with the loading of google map?

  It is very likely.  If iPhoto work very well when you are offline, then your problems will be caused by the connection failed to Googles servers.

• synchronize two number of cycles

  Hello world!

  I want to synchronize two number of cycles. I want two number of cycles to start the countdown together. I have two check County file VI, which was attached. I would like to ask if two ticks start at the same time counting.

  I thank in advance.

  In LV, you don't 'start' a number of cycles. The counter tick count functions interact with which is a 32-bit counter that starts when the fact of LV. You can compare the number in two places in your code, and can be assured that they are both reading from the same starting point.

  But I am totally confused by your code. What you trying to do?

• Install Oracle GoldenGate Linux to synchronize two schemas from database on a single server

  Hi all

  I have to synchronize two schemas from database (Oracle 12 c) in a single host RedHat Linux to demonstrate and understand the use of OGG V12.1.2.1.0. I try to do. But it's complicated and confused me because I am new to Oracle and Linux. I followed this tutorial ( install Oracle GoldenGate for Oracle 12.1.2 on CentOS/6.x to 6.x/RHEL Linux 6.x EL ). But it is difficult to understand how I can match with two diagrams of database on a single server.

  
  And I found this tutorial (Oracle GoldenGate on Linux: two-way replication of Oracle 11 GR 2 to Oracle 11 g 2). He said: "" If you have that one host, it may be useful to change the /etc/hosts file to create aliases forhost01.example.com and host02.example.com.". What it really means?

  The other seems to be useful. But it's totally different from 1. Is that this will help my job since I use 12 c Oracle Server?

  Can I get some tips to continue my task?

  Here's another tutorial - http://www.oracle.com/webfolder/technetwork/tutorials/obe/fmw/goldengate/12c/OGG12c_Integrated_Replicat/index.html

  It has everything set up on a single Linux host.

• Synchronize two schemas from database on a linux server using Oracle GoldenGate

  I followed this guide ( http://www.oracle.com/webfolder/technetwork/tutorials/obe/fmw/goldengate/12c/OGG12c_Installation/index.html?cid=9167 & ssid = 0 ) and for two different databases running on the same instance of database schemas.

  
  What I have now is a Linux server with two Oracle database schemas. I have access through my Linux virtual machine. I want to do the synchronization possible between them.

  I use Oracle GoldenGate to make this possible. What should I do now? Goldengate is must be installed in the server too? I'm totally new to this situation. Can someone give me at least the major steps before going to the more comprehensive study?

  Well understood. This helped.

• PE3 is possible to synchronize two sources video post edit AB Roll?

  In PE3, is it possible to synchronize two digital video files (AVI) to create an AB roller type post edit.  My two captured video files seem to have different speeds or od frame.  How do I align and frame corresponds to 2 video sources?  The situation is a 2 photo shoot.  How to best create a roll of AB edict of sources 2 videos with audio of a video file as a common element?

  Wes,

  Armed with Steve's article, you should be able to do what you want.

  I have a question and maybe a suggestion to fix the problem of pace from the start, to help solve this problem without a lot of fiddeling. What are the two frame rates? G-Spot will tell you exactly, if you can't find it in the properties. If the source files are DV - AVI, they must be of the exact same rate initially, but if you're a little off, I would like to convert it the DVD specifications do not support a correspondent. First place I would try this would be to simply interpret footage in the project Panel. If this does not work, then Windows Movie Maker can do for you, or you can use other conversion tools to match. I use DigitalMedia converter, but it's not freeware. Get the two sources in perfect sync at the beginning will go very far to the success.

  Good luck

  Hunt

  [Warning] I don't have PE3, PE4 only, but I think that applies to your version.

  [Edit] After reading the article by Steve, the only thing I would do (after the sync property) to help me in the multi-cam editing would be to set the video track display to show all the "frames" and the expansion of the height of each video track two (VT), so that they occupy the largest part of the vertical real estate in the timeline. Then, I would zoom in on the horizontal of the timeline display, so that I could see quite clearly, each image. Basically, this makes the timeline as a line of detailed scene, but you can stay in Timeline Mode. Because you do not have Mode multicamera PrPro, you won't get anything your video footage track higher in the program monitor. You will be viewing the images on the Timeline. This will require a lot of horizontal scrolling on the Timeline, but it is doable. Then, when you want to use the images of VT1, you will cut (scissors tool) VT2 overlay images. Personally, I work out my main sequence (such as the master in the article Steve Audio track) on VT1 and images from my camera "cutaway" on the VT2 console. Like prescedence VT1, VT2 you can leave VT1 footage almost alone and just cut the images on VT2. I would use the Cross-dissolves on the head and the tail of the "Cup" Clips to VT2. Remember that if you use these, you want to make sure that the cutting came where you want the scene on VT2 absolutely start or end. The duration of the cross-dissolves will determine when the stage becomes either visible at 100% (head), 100% invisible (tail). Also, don't forget that Dip - to-black on VT2 takes the image on VT1 to black, where my use of Cross-dissolves.

  Using this method, can also do some repositioning of the (cut from the original) Clips to VT2, to offset any loss of synchronization. But you can possibly use it to set the framerate differences, I'll try again to get the images as accurate, as it is possible to start - a lot less work in this way. Also, once the 'holes' were cut into the images on VT2, you can start using the program monitor much more.

  As Steve points out, PrPro facilitates locking securities and a double multiple camera monitor, multicamera mode.

  This is exactly how we did with film, except that we had to splice in black leader, where cuts were made and could not hold our intact VT1 sequences, we can with an NLE and video. Because we were dealing with sprocket holes, we had doped (sprocket) gears on a 'sync' block, and once we'd get right alignment, would physically renversible by a guide, who would 'lock' the film to these two rolls of film for the sync block. Although it may seem difficult, when you read it, it's really not and so very easy, as it was with the film.

• synchronize two usb 6289 with a meter

  Hi people!

  I'm trying to synchronize 2 boards of the series M USB-6289 using a counter.

  I searched the forum and that you've already seen the tutorials:

  'Synchronization of series M with LabVIEW and NOR-DAQmx - Developer Zone - National Instruments'

  'Synchronization of data acquisition USB - device to several systems - Developer Zone - National Instruments'

  "The time and the synchronization of the NOR-DAQmx - Developer Zone - National Instruments features."

  However, I still have some doubts (where the post with respect to the following:)

  -If I want to use the meter as trigger for both cards do I need to export to a PFI line and connect to the Member of the Board?

  -I do the same thing with the clock signal (export to the other panel using a PFI line) or using the same frequency for two meters is enough? Or both?

  -can I use the same value for the frequency in the meter and two clocks?

  Hope someone can help out me.

  If possible, underline some examples or detachment would be great.

  Thanks in advance for the help!

  See you soon!

  Hello

  All points depend on what you need to synchronize exactly.

  As you have probably already read in the links you provided, you have the option to share a trigger, or a clock, or both.

  Of course, the best solution is to share together.

  Then, you can choose to directly share the sample of one blade to the other clock (if the two sampling rates are the same), or to move the reference clock, then, both cards will synchronize their sample (with PLL) clock on the same reference clock, as shown in the synchronization M with LabVIEW and NOR-DAQmx series.

  Exactly how you want to use your meter?

  You want to generate a single trigger pulse?

  Then, for examples of synchronization, there are some zip files at the end of the links that you have read.

  Kind regards

• Synchronize two E-card with traditional DAQ series

  Hello

  I have a PCI-6052E and a PCI-6071E and I have a Matlab program that interacts with traditional hardware DAQ driver cards.

  It is possible to synchronize the two cards use RTSI or something? If so, what should I do in matlab to achieve?

  I'm a bit confused, because I don't know if this is only possible using DAQmx.

  Thank you!

  Hi zlyhere,

  Using DAQmx would definitely be the best choice.

  In terms of using C vs the Data Acquisition Toolbox for The MathWorks Inc. Matlab® Software, I would recommend the Toolbox for ease of use.  The MathWorks develops the Toolbox, so they must have documents on how the maps can be synchronized.

  If you find that you need more features, you can fall back to C.  Documentation is available at

  "" "" Start menu"all programs" National Instruments "NOR-DAQ" support textual Code ' using NOR-DAQmx C reference

• How can USB-6210 I synchronize two channels of ctr

  Hello

  I use LV 8.5.1 and NI USB-6210. A small application I want to generate two different impulses with synchronization but simple starting point. When I configure a task with two channels the second channel configured always starts a ms later. But, if I configure both channels in terms of frequency, they start synchronously.

  My idea is bad in general? The DAQmx part is fixed.

  Thanks in advance

  Hi there, too.

  the release of the finite pulse trains, to two meters for each task. Therefore, your application will be the first impulse using two output counters and then to exit the second impulse using the two counters.

  Like the USB-6210 don't not have outputs DIO correlated, you'll generate two infinite pulse trains (which can be started at the same time throug a trigger of arms) that you explicitly stop before the start of the second pulse (using the DAQmx abort task from a parallel loop), or upgrade your hardware at least a USB-622 x card series and a digital output model... Alternatively, you can use the PCI-6602 counter card and use a counter to Gate two others doing an infinite impulse train uses a relaxing break...

• synchronize two loops for written tdms data acquisitions

  Hello

  I have two loops of different data acquisition. A slow acquisition of CAN (10 s/s) and an analog acquisition faster (30 samples taken at a frequency of 300 Hz), I need to synchronize these data for tdms writes for later analysis in DIAdem.

  My example and the result in the DIAdem channel list is attached.

  Thanks in advance!

  Magnus

  Magnus,

  for a professional solution, you do not want to synchronize the devices on a hardware level. Since the material CAN work differently to 'traditional' DAQ devices, there are important things to take care of.

  Please look in the viewfinder to LV example for the word "CAN". For example, you can choose the example 'several cards CAN and DAQmx map Wfm Input'.
