Filtration of single-point data

Hello, I'm trying to filter the data of voltage point unique task, but there is an error of frequency... I have set at 120 Hz sampling frequency and I want bandpass filter for example of 30 to 40 Hz...

So, where is problem? I tried to use a timed loop or "align and re - sample" sampling frequency, but this filter still does not work...

You know, how to use this filter with single point task? When I do my own filter FIR with the same settings, the results are not same, this is the reason why I want to use this filter.

If I use DAQ Assistant, there is no errors, but I can't use for other reasons (1) I can't use single point and all daq assistant, daq assistant 2) can't do pressure)

These images add nothing to the discussion. If you buy a single point at a time, you have NO frequency and cannot use the normal filter function. Do what I said or use multi-sample reading or single reading point and build the table before making a filter. Best is to use the acquisition of data with several samples.

  • pl/sql block, reading the reading of data from the table to a single point in time

    I'm trying to figure out if several cursors in a PL/SQL block are executed inside a single Point in time, and so don't see no updates of paintings by other processes or procedures running at the same time.

    The reason why I ask is I have a block of code as an initial extraction of data, with some Sanity Check before the code runs. However, if another procedure might modify the data between the two, then the mental health check is not valid. So I am essentially trying to know if there is consistency read in a PL/SQL, preventing updates to other processes to be seen.

    Anyone who has an idea?

  • Single-point PXI 8106 timed performance material

    Hello

    I'm potentially interested in buying a PXI-8106 module for my application of servo motor control. I would like to know that single-point timed material loop rate performance of this command when used with DAQmx, before buy you. Does anyone have statistics of performance for this controller to the benchmarks of NOR (http://www.ni.com/white-paper/5423/en/)? Ideally, I'd be able to get execution rate of loop for T1 to T4 tests, for 1 and four lanes. I can't find this info online.

    I am currently borrow a PXI-8108 for my setup and I can reach nearly twice my goal of 2 kHz loop rates. I also know the performance of the 8108RT to the above reference, so if I had the same numbers for the 8106 I should be able to judge how the 8106 happen for my application.

    Thank you

    Hello

    We do not have these data posted, but looking at the specifications for these two cards, I imagine that you would see no more than a 20% drop in performance between the two.  Probably less.

  • Finished samples timed material vs single-point: different speed?

    Hi all

    Although I had several questions about this request before that separately have been resolved, there is one last thing that remains difficult.

    Shortly:

    My application acquires data from 2 analog and synchronous inputs on 2 channels of analog output.

    There is a trigger stop set on a PFI-pipe with a single switch. To make of this

    I had to switch from single-point over acquition timed work material.

    This set works very well when I read not less then a 100 samples once with a sampling of 1000 Hz. frequency (when I go below a sample of 100 to read--> E-200279)

    Ideally, I would like to read about 10 samples with a sampling frequency of 1000 Hz.

    However, using single-point timed equipment acquisition I can easily do that without a problem. Even just reading

    a single sample once with a sampling frequency of 1000 Hz does not have a problem. But impossible to use the block of relaxation of reference as a signal to stop with this setting!

    Question:

    For me, there are two solutions, but so far I could not work on one of them:

    (1) build a stop trigger in an single point of timed material acquisition

    (2) change something in the acquisition of finished so that I can read faster.

    Any suggestions, what causes the difference between the two speeds to be able to read the data and a way to solve it?

    Thank you

    Mark

    Mark,

    I mocked how I think I would like to address the issue and tied it to the top.  The general idea is that we use HWTSP for our analog I/o and counter looking edges on our signal "stop".  Each iteration of the loop, we check if we saw the stop signal.  If we have, then we write zero for the output channels and stop the loop.  If this isn't the case, write us the data of your comments, we have calculated.  I've added some comments on the block diagram that I hope are useful.  I have currently no any material of series E share, so it may not work properly out of the box, but I thought it would point you in the right direction.

    I offer this precaution:

    Windows is not a real-time operating system.  Therefore, it may take the liberty to give as much CPU time to other processes or applications as he likes.  As a result, it is likely that you will not miss a few samples (IE, your loop will not go faster hardware issues are examples of clock).  I configured DAQmx must return a warning you when this happens.

    Hope that helps,

  • Single point of failure/Cluster/high availability on Essbase 11.1.2

    Hello

    The project I am currently working has only one Version of Unix 11.1.2 Essbase server that's threat as a single Point of failure. Management thinking to upgrade the Essbase to superior verion 11.1.2.1 to achieve clustering & high availability and to overcome the situation of single Point of failure by having just a server unique essbase.

    My concerns here are;

    Note: Essbase in this project is used to generate reports only, write back data is not allowed.

    (1) not supported of the Essbase Version 11.1.2 Cluster / HA / failover to the other node?

    (2) if it is Yes, can you please share the link to the documentation for this version 11.1.2.

    There are other components of Hyperion as HFM, FDM used the same version in this project. If the failover is not supported in the version of Essbase 11.1.2 we need upgrade other components as well as the Essbase or just Essbase upgrade upgrade to version 11.1.2.x is sufficient.

    Please share your valuable thoughts on that.

    Thanking in advance for your ideas.

    Kind regards

    UB.


    Found the reason why Essbase Cluster does not work when implemented with failover / high availability when Essbase Analytics link (EAL) used in the project. Due to these facts, we have stopped application Essbase Cluster and the Essbase in my project remains SPOF (Single Point of Failure).

    Not sure if Oracle Corp. comes with EAL product improvements that can take over for Essbase Failover.

    "

    1. Essbase Analytics link (EAL release 11.1.1.4) does not support high availability facilities. This means that EAL cannot connect to a cluster of Essbase, always happens only connections to a server regular Essbase through the Regional service console. Although we can define availability high for Essbase, EAL will use a single Essbase server. If it breaks down another Essbase server is used, we must manually redefine the EAL bridges on the new Essbase server and re-create the database Essbase. It is not considered high availability in this case.
    2. There is no technical mechanism to link point to a Cluster Essbase-Essbase analytics. EAL is supported only to connect to a single named Essbase Server.
    3. Transparent partitions can support when configured Essbase as component availability high when EAL is used. EAL bridges in the active project uses Transparent partition.

    "

    Please feel free to correct me if this interpretation is wrong.

    Thank you

  • When I clik on a link to view another Web page or another document, a blank page appears (a single "point of png'). How can I solve this issue?

    The links are located on the emails I receive from authorized sources. When I click on the links to read the additional documents (another document) or display a picture, I get a blank page with a single point in the middle of the page. The tab header says it's an image (1 x 1 pixel) PNG. Any suggestions to fix this?

    Often, links to email in bulk are routed via a follow-up rather than service directly to its final destination. If you look at the address bar on the image page, it seems like one of these intermediaries rather than the page you expect to load? If you click on the address bar and press ENTER to retry the address, which does nothing?

    It is possible that the security software or security add-on kills a redirect from this intermediate page to the final destination. For example, I think the anti-banner Kaspersky functionality could do that.

  • The fixed Point data

    It is possible to specify the length of Word and whole for the fixed point data format, and if so where this work?

    The module I use is a NI 9205 in a cRIO-9074 and seems to have a fixed point default data format of <+-, 26,="" 5="">, which I interpret as meaning that the data is signed, has a length of 26 Word and a length of whole number of 5. This gives a maximum of 16, a minimum of-16 and a size of minimum step of ~4.768 x 10 ^-7, that is to say 1/2 ^ 2.

    Could someone please confirm that this is the correct interpretation, and also explain how it is possible to obtain a length of 26 Word when the analog digital converter / base is only 16 bits.

    Hello Magnus,

    first that I want to recommend the "single-point input Signal Mode" in the XNET help (first link in the XNET (single-point Signal) reading .vi) article for a better understanding of the feature.

    If you wish to set up an audit of the time-out period, you can use the function "XNET .vi (XY Signal) read", so that you get a delivery timestamp. When query you that you can build a lag.

    Your code is extremely difficult with all these interiors FOR loops and sequence in unnecessary structures, etc... Simplify!

    Try to start first with some tutorials.

    Using average-ptbypt for the top 10 values, add to the table you have 10 values, then start adding unique values. Here is a quick sketch.

  • WAP321 two Pat same SSID on the same piece with the installation of single point / cluster

    Hello!

    It has bought several WAP321.

    We have a room which has about 40 books, so I will deploy the two Pat in there (according to recommended 20 clients per WAP on specifications).

    I configured the first WAP, created a cluster and the SSID, then joined the second WAP to the same cluster with the installation of single point, he received the same cluster radio settings (SSID, WPA2 key, etc.)

    My requirements are:

    1: configure all laptops with the same unique SSID created on the WAP (which has spread to the second WAP via single point of installation/cluster)

    2: having the laptop connect automatically to one of the Pat.

    3: If a WAP fails, the laptop can connect automatically to the other.

    Is this possible?

    If Yes, are the measures taken are correct, or is there something else? (and how does the cell know what WAP to connect if two WAPS is configured with the same SSID?)

    Thank you very much!

    Hello

    Thanks for posting your question on the forums.

    Setup you had set up will work fine for your application, I highly recommend to make sure that you have two AP running on different statically assigned channels, you can put one on channel 1 and the other on Channel 6 or 11. This will prevent them to conflict with each other.

    Now, there is no real way to select what AP you connect or even know that you you already connected to without special software, in fact, when a device gets on the network and seeking to connect to the radio will connect to the first point of access that meets the demand, if it is no longer available then it forwards the request again and it will connect to one who works.

    I hope this helps. Please let us know if you have any other questions

  • SAN FISICA E Single point of Failure

    Ciao Tutti,.

    Prima di implementare UN progetto per UN nuovo client, I wanted sapere cortesemente some info riguardo alle SAN BROTHER (DELL, HP, Netapp ecc.):

    The SAN BROTHER hanno dei point single failure? MI spiego... oltre ad avere a controller, doppie nic, alimentatore ecc doppio doppio. esiste a componente called che e singolo backplane? e if as rompere questo SAN e offline?

    Pole enjoied all all di una DELL PowerVault MD3420 con tutto ridondato. my he dubbio era is esiste a componente nelle SAN BROTHER (come the scheda madre x I have server/host) che non Può essere ridondato...

    The Altra soluzione era quella di passare una virtual SAN... ad sapete consigliarci a sistema di SAN VIRTUALE apartment VIRTUAL SAN di vmware? e magari darci some info su Dove find advantage?

    Grazie a tutti by attenzione.

    The maggior parte degli storage company entered o middle level hanno nello o chassis backplane he loro single point of failure.

    ORA by primo of quinto if it io no ho ricordi di aver may heard parlare di sostituzione by guasti ecc.

    Mentre by her seconda della backplain Può anche understand parlo. The bkn di guasto pero worth bassa che viene e no may almost considerata.

    Questo perched if di is a componente del tutto passivo. E' una scheda elettrica di interconnesione tra i controller I have brain gli alimentatori ecc.

    Questo tipo di construction appartiene a quali prodotti HP MSA, NetApp 2500, IBM's DS, solo e DELL EMC VNX by some citarne.

    A che non condivide backplai e ad esempio una sistema he StoreVirtual di HP. In questo prodotto ogni controller e composto da Server x 86 con i suoi brain.

    SE cerchi invece soluzioni tipo SAN virtuali, you can always see it sopracitato StoreVirtual oppure I prodotti di StorMagic, StarWind, Datacore solo ecc by some citarne.

    Personally a meno che he tuo sistema sia company highly critical non mi if tanti pensieri e punterei ad uno degli storage classics di cui ti ho scritto sopra.

    SE invece affidarti ad una soluzione perched software non proprio valuti you want the VSAN di VMware?
