Problems with counter on 9411

I am a new user of Labview, so it's a little intimidating. I am using a cDAQ-9188 with several modules but I have problems with one is the 9411 is used to measure the speed off the coast of a torque meter.

I joined the program I put in place. What I want to do is to measure the number of edges on a 3 second interval so that I can divide by the number of pulses/turn * 60 * 1/3 to receive the RPM. However, the number of edges behave linearly as I expected. I measured the speed of the shaft with a light strobe and represented graphically it vs the number of edges. The results are attached to the excel file.

What Miss me? The number of edges should not increase as speed up the tree, or I'm going about this all wrong and is not what I think I am?

Thanks in advance.

Ahh ok, that make more sense - it seemed like a strange to report a couple measured, way but now I understand that your torque sensor also rpm through this collection of speed option and that's what you ask the subject (I can't see not how pulses/turn the sensor is on the site Web of Honeywell however, do you know offhand?).

The software timing 3 seconds will implement much of the variability in your measure but would not explain the strong negative correlation between the RPM and the speed sensor (we're talking several ms of non-determinisme for a second window 3) output frequency.  Finally, you'll want to solve this problem as well, but it is not your problem right now (as an aside - it would be actually more accurate to measure the frequency of the signal encoder using the 80 MHz as a reference time base and average the result on a second window 3, the general idea is sort explained in manual of 9188 here but I digress).

I think it is more likely that the signal from the speed sensor is a bit noisy (pretty typical of optical encoders) and then transitions the 9411 is picking up multiple edges.  A slower RPM equals longer transitions and therefore more false edges.  It is just a hunch, but that's what I can think of on the top of my head that could be causing what you see (if read number of pulses is higher than what you expect, given the pulses/turn of the sensor through all ranges of RPM that it would support my theory).  If you want to ignore the method of measurement for a second and try to solve the problem of noise (assuming there is one), you can add the following property node to your existing code before you begin the task:

You can start by setting MinPulseWidth to 6.4us (which is one of the built-in clock dividers available for PFI filters on the 9188).  You want the MinPulseWidth be short enough to ensure detection of a legitimate impulse, but long enough to block all wrong edges that occur during transitions.

Best regards

  • Problem with counting function, passing VARs between functions.

    Hi guys, I have a problem with this section of code...

    Could anyone suggest how to fix the function at the bottom so that when the button forward_btn with label "go to next Point training" when you click on recalculate the fields created in the function fileLoaded

    var xmlData:XML = new XML ();
    var theURL_ur:URLRequest = new URLRequest ("xml.xml");
    var loader_ul:URLLoader = new URLLoader (theURL_ur);
    var more: RegExp = / \ + / g;
    var t:Number = 0;
    var tmax:Number = 0;

    loader_ul.addEventListener ("complete", fileLoaded);

    function fileLoaded(e:Event):void {}
    xmlData = XML (loader_ul.data);
    Tmax = xmlData.Record.length ();
    trace (tmax);

    trace (unescape (xmlData));
    trace (xmlData.Record.length ());


    var title_tp:String = unescape(xmlData.Record.TP.Title[t]).replace (, "");
    Title_TP_txt. Text = title_tp;

    var intro_tp:String = unescape(xmlData.Record.TP.Introduction[t]).replace (, "");
    Intro_TP_txt. Text = intro_tp;

    static_tp_intro.y = Title_TP_txt.y + Title_TP_txt.textHeight + 10;
    Intro_TP_txt.y = sta_tp_intro.y + sta_tp_intro.textHeight + 5;

    Title_TP_txt. AutoSize = TextFieldAutoSize.LEFT;
    Intro_TP_txt. AutoSize = TextFieldAutoSize.LEFT;
    }

    forward_btn.label = "go to the next Point training";
    forward_btn.addEventListener (MouseEvent.CLICK, next_if);

    function next_if (me: MouseEvent): void {}


    If (t == tmax) {play();  }


    else {t = t + 1;
    fileLoaded () ;}
    }

    I don't see where you have a question from vars between functions because you do not pass everything.  Maybe that's your problem.  The function fileLoaded expects an argument, but you are not providing one.  To get around that you should provide any argument being sent in the first function...

    function fileLoaded(e:Event=null):void {}

    Another option would be to separate features and put a quick end to the function fileLoaded and create another function that holds the rest of the code...

    function fileLoaded(e:Event):void {}
    xmlData = XML (loader_ul.data);
    Tmax = xmlData.Record.length ();

    processXMLData();

    }

    function processXMLData (): void {}
    trace (tmax);

    trace (unescape (xmlData));
    trace (xmlData.Record.length ());

    var title_tp:String = unescape(xmlData.Record.TP.Title[t]).replace (, "");
    Title_TP_txt. Text = title_tp;

    var intro_tp:String = unescape(xmlData.Record.TP.Introduction[t]).replace (, "");
    Intro_TP_txt. Text = intro_tp;
      
    static_tp_intro.y = Title_TP_txt.y + Title_TP_txt.textHeight + 10;
    Intro_TP_txt.y = sta_tp_intro.y + sta_tp_intro.textHeight + 5;
      
    Title_TP_txt. AutoSize = TextFieldAutoSize.LEFT;
    Intro_TP_txt. AutoSize = TextFieldAutoSize.LEFT;
    }

    forward_btn.label = "go to the next Point training";
    forward_btn.addEventListener (MouseEvent.CLICK, next_if);

    function next_if (me: MouseEvent): void {}

    If (t == tmax) {}

    Play();

    } else {}

    t = t + 1;
    processXMLData();

    }
    }

  • problem with counting seconds

    I found this function

    SELECT

    TRUNC (86400 *(date_to-date_from))-60 * (trunc ((86400 *(date_to-date_from)) / 60));
    TRUNC ((86400 *(date_to-date_from)) / 60)-60 * (trunc (((86400 *(date_to-date_from)) / 60) / 60));
    TRUNC (((86400 *(date_to-date_from)) / 60) / 60)-24 * (trunc (((86400 *(date_to-date_from)) / 60) / 60) / 24)),
    TRUNC (((86400 *(date_to-date_from)) / 60) / 60) / 24)

    IN tempsSec, tempsMin, timeHr, heureDAY

    FROM DUAL;

    Nice and easy compare two dates and return the (time) difference as 13 hours, 40 minutes, 10seconds

    now, my system shows delays like this from 10:00 to 10:19 (which is the duration of 9 seconds if you use the function above).
    now, what I tried to do is to add 1 second of time, since there are between 10:00 and 10:19 actuially 10 seconds elaps (0 to 1 (1 second), 1-2 (1 second)...)

    so I tried to just add a seconds before the date_to

    SELECT date_to + 1/24/60/60 INTO date_to FROM DUAL; -Add a second because 00 09 is 10 seconds of display time (not 9!)

    but sometimes, this provides a valid information, sometimes when counting only seconds each presents a wrong time, so there is an obvious mistake, I do somewhere...

    Rather than trying to debug the code you posted, it is probably easier to convert dates to timestamp, subtract the timestamps whiich returns an interval and extract the components of the interval.

    Note that I add 1 second in the inline query. For the subtraction normal timestamp, you who would remove.

  • Problem of IR with COUNT (*) (AS apxws_row_cnt)

    Hello world

    I use the same question raised in the IR problem with COUNT (*) () AS apxws_row_cnt discussion Forum, by Marco 1975. I'm developing on APEX 5.0.0.0.31 and using the Oracle 12 c DB. An IR translates 4648 occurrences only 100 records. The SQL is okay, but the OVER() COUNT (*) AS apxws_row_cnt done something witcthery on my report.  Anyone has any idea how to solve this problem in 5 APEX?

    My query:

    SELECT PK_EMPLOYEE,

    DATE_HIRE,

    DATE_QUIT,

    DBMS_LOB. GetLength ("foto") "FOTO"

    NAME,

    CPF

    OF TB_EMPLOYEE

    I found, helped by 3rd party experts - CITS Brasília - workaround using nested selects to avoid the Cartesian product of my request on IR. This is a Cartesian product of column FOTO ("PHOTO") against a column of master FK from another TABLE.

    In any case there is the solution, I'm sorry for the Portuguese terms, but I understand that it will be quite understandable:

    SELECT DISTINCT NULL as apxws_row_pk, "PK_EMPREGADO", "CPF", "NAME", "FOTO", "DATA_CONTRATACAO", "DATA_DISPENSA", count (*) (as apxws_row_cnt)

    FROM (SELECT * FROM ())

    SELECT

    b."PK_EMPREGADO."

    ----------------------------------------------------------

    --> Cartesian product: PHOTOS N versus Post - Posto Trabalho work 01

    -"FK_POSTOS_TRABALHO"

    -------------------------------------------------------------

    -nvl (L1. ("" "' DISPLAY_VALUE ', b." FK_POSTOS_TRABALHO ") as"FK_POSTOS_TRABALHO,"

    ------------------------------------------------------------

    «"" "" "" b."FCP", b."NOME", b. "FOTO", b. ' DATA_CONTRATACAO ', b. "DATA_DISPENSA»

    FROM (SELECT * FROM (select distinct emp.) PK_EMPREGADO, emp. FK_POSTOS_TRABALHO, emp. FCP, emp. DATA_CONTRATACAO, emp. DATA_DISPENSA, emp. NOME, dbms_lob.getlength (emp. FOTO) "FOTO".

                  OF TB_EMPREGADO emp

    RIGHT JOIN TB_POSTOS_TRABALHO_HOM pt ON (pt. PK_POSTOS_TRABALHO = emp. FK_POSTOS_TRABALHO)

    TB_EXECUTORES of RIGHT JOIN ex WE: APP_USER IS NOT NULL and: APP_USER = e.g. MATRICULA AND pt. FK_CONTRATADA = e.g. FK_CONTRATADA WHERE emp.cpf IS NOT NULL

    ) ) b,

    (SELECT NUM_CONTRATO |) ' - ' || DESCRIPTION as display_value, FK_POSTOS_TRABALHO as return_value

    OF terceirizado. TB_CONTRATADA cont, terceirizado. Post TB_POSTOS_TRABALHO_HOM, terceirizado. Tipo TB_TIPO_HOM, terceirizado. TB_EMPREGADO emp

    WHERE to post. TYPE = type. PK_TIPO and cont. PK_CONTRATADA = post. FK_CONTRATADA and emp. FK_POSTOS_TRABALHO = post. PK_POSTOS_TRABALHO

    L1 OF THE ORDER OF 1)))

    I hope that Oracle will provide a coherent solution for COUNT (*) () AS apxws_row_cnt question.

  • Problem with output 5VDC NI 9411 channel

    Hello

    I'm having a problem with output 5VDC NI 9411 channel. According to the specification of the module, it was stated that the module required external power from 5 to 30 VDC. Game of supply the module with the requirement of tension, I am still unable to get the output voltage of the output channels. Does this mean that the output voltage may be available depending on the program?

    Thanks in advance,

    Kind regards

    Mike640

    Hi Mike,.

    Thanks for posting on the forum of National Instruments.

    You should still be able to get an output voltage in properly feeding the NI 9411 and your external device.

    If you don't have a power supply of 5V to power the external device directly, or if you want to simplify the cabling, you can connect an external power supply to the Vsup and COM terminals on the connector terminal block screw NI 9411 and connect the external device to one of the pins Vout + 5. If the external device is already powered, you have not need connect a power supply on the NI 9411 or plug the Vout of + 5 to the external device.

    I hope this helps.

  • I have problem with my Apple Watch, during the step count of the market does not appear on the watch?

    I have a problem with my Apple Watch, when I use the watch on my treadmill, keep the phone, the number of step does not appear, the whole market is a waste if it shows only not on Apple Watch, how to solve this problem?

    Hi Shabbir

    Apple Watch has two integrated health and fitness apps: enforcement activity and the application of the workout. For best results, make sure your arms naturally swings while walking on the treadmill, as Apple Watch uses movement of arm (measured by the built-in accelerometer) to track and evaluate movement for indoor activities. If you use the application of the training session, your watch will also measure your heart rate continuously for training in order to estimate the calories burned.

    Check that you have configured the application of the activity:

    -Press the rings activity on your watch dial or open the application for the activity (if you have not set it upwards, you will be prompted to answer a few questions).

    Also, make sure that the fitness of tracking is enabled:

    -On your iPhone, in the application of Eve, go to: Watch My > privacy > Motion & Fitness > fitness monitoring.

    You can improve the accuracy of the estimates related to activity in calibrating Apple Watch (take your iPhone with you on walks outdoors or tracks, connected to your Apple Watch and with location enabled Services - see the detailed instructions in the article to support below).

    I am treated to a new computer laptop last Saturday and only had for about 3 and a half days so far but I noticed a few things that I wasn't sure were errors/defects or if it was simply because its news, like the fact that sometimes I type with the keyboard and some letters do not appear on the screen , I think it's probably more to do with me not type or support pretty strongly on the keys rather than anything else, his is not so much now... the touchpad becomes a bit sticky too and he thinks I want to scroll up and down when I move the cursor does not scroll sometimes but I managed to make it work I think that most laptops have glitches like that and no doubt I could help fix it in calibrating the pad (?) touch I did have time to consider the issue and yet if... There are a few other things well and more disturbing than this morning I got an error of video material, so now im a little just worried or suspicious that it may be a real fault with him and would like to know if it is the case, if its something I can fix eventually (im no expert especially with the material, but I can always try to download and installation of updates / corrections and this kind of thing so she could solve the problems).

    The main thing that concerns me more, is that this morning a message suddenly come to the screen, warning me that there was an error in video material, last night, I clicked on a button, I think for load more information. and I took this perforated cap of it: -.

    I thought it may be useful to view the actual complete message rather try everything and paste the info., ok to be honest I've not noticed it allow you to copy to the Clipboard, but good (oops lol).

    I know there is a topic on a similar error, but I didn't want end-to-end on this discussion because I assume that it should be for this mistake of people who will be discussed, mine may be slightly different, I don't know... I followed the instructions given in this discussion and I checked the Device Manager and no material defects are appearing, btw it is said in the Manager of peripheral devices, graphics cards, it's a Mobile Intel 945 GM Express Chipset Family, I'm sure that all laptops A200 15I have the same card, but I thought I would just make it clear that. Incase that wasn't the right thing to check I also checked under "Audio, video and game controllers" (as the error says it was a video hardware error) where it lists the only as being "Realtek High Definition" Audio and I checked the properties, both under properties it says that the device works properly, without signs of defects...

    The thing is, I had read somewhere online that there is a problem with the graphics or video cards. I had read that they can be glitchy and sometimes break after a year. I also asked my father about it and we looked at it as a graphics card Intel that came with this laptop, which it is, and we counted that the Intel chips is as reliable as any other brand really... so I don't think there should be a problem, well that is there I have until September next for repair prior to the expiration of the warranty!

    What surprises or sort of worry, however, is that the error message was only introduced to me this morning. It dates from error, as having occurred at 19:53. I use it at night last, and infact, I went to take a shower and I put the laptop down before you go take a shower at around 19:35, I assumed that its ok just close the lid and it would automatically go into hibernate mode or something similar (?) im wondering if that had something to do with it as I 19:53 would have been about when I came back and lifted the lid/screen again to use the laptop again... I can only assume, given the time, he cites, is what caused the failure?

    It gives me the option to "update driver software" and "hardware change analysis" in the Device Manager, can I run both, or one of those who maybe? is this a common problem? should I worry at all etc...

    Any help is very appreciated, if more info. Please let me know and ill clarify what I can. Also in terms of whats installed, I have quite a few programs, for graphics, I have an old version of Paint Shop Pro, which I installed it yesterday morning, it seems to install fine, it is Jasc Paint Shop Pro 7, I have also some programs of converter (for files vid, 3GP and other things), scan antivirus AVG, Spybot Search & Destory DBPowerAmp, FTP Commander, Quicktime and Real Player, pretty basic stuff like that, nothing, just my old photos and vid files I transferred from my old laptop XP to it, in my documents... I don't have all the Senior Games motorized or complicated or anything else like that installed. Also at that time, indicates the video hardware error message, everything that was in progress when I got the cover down (or before putting the lid down) would have been Windows Live Messenger (although I'm pretty sure that I registered before putting the lid down) and an IE window , im pretty sure that's it, I was not working on anything just check the ' net...

    There are other things I noticed as I thought that maybe I should mention (?), something I've noticed he's doing is the screen goes blank and then back very quickly, a lot. I already asked about it a day or so there at that time, I realized he was only doing that before loading the "Windows needs your permission to continue" window/message, who apparently its supposed to do and something to with the computer to switch to display the normal desktop to the secure desktop, I kind of understand lol.
    So I think that's not something to worry about but I noticed during the lastday, that the screen seems to do it more, goes blank then back again, even if the authorization message does not appear.

    For example, this morning, when I first put on and am went to check out my home page, I clicked on a link at the bottom of the page or anywhere where to load another page into the site and display deleted for a while before coming back a second later with the requested page. Is this normal too? or an associated Vista glitch, or is it possible that there may be a small problem with the monitor? Incase of im guessing it can be more than one thing in Vista, but I thought I would ask here, I decided to not pay for any extra insurance/warranty extension because I am very careful with my items and take care of them and so I'm being careful to try to spot defects early, while they may be repairable under the basic warranty and what-not...

    Another thing I noticed is that start with, when I pressed on and kept the 'FN' key, a variety of icons, black and white appeared on the screen that told me what F button (s) to use to make certain adjustments, there still is that when I try right now, but at other times, it does not show icons , no matter how long I hold down the "fn". That didn't matter because I can tell by the symbols on the keyboard press what buttons but its just inconsistent, is there a reason why sometimes the row of icons on the screen will appear when I press and hold the "FN" key and other times it doesn't show at all?

    Also sometimes if I move the slider to the right to the top of the screen, these icons loading as they always seem to be located at the top of the screen, but sometimes it's a problem, if im trying to click on something else and one of these icons rises instead... I'm sure that you can disable this option in sort , but I'd be worried that the icons do not always show when I press and hold the right Button (?) just try to be careful!

    I think that this post is long enough and I don't see what else I could possibly add to help, so I'll leave this here. I don't want to sound too paranoid, but thought it is better to talk about this kind of things incase someone recognizes these defects/errors and can recommend a way fast to resolve potential problems before they can develop into what whether it is worse... Thank you very much in advance for any help on any of these issues!

    (mods let me know if im wrong to include so many things in a subject, I fact kind of this quickly and I apologize if im breaking any rules, I don't want to, if possible please break this into a few different themes or I can do it, although ill be at work frm 2-21:00 today so maybe not back and able to check here until Thursday morning (October 4))

    Hey Isla

    Your message is really very, very long. I think it's too long to read twice ;) s

    . Regarding your questions on this laptop well. Looks like you have installed many applications and 3 third party programs. In such cases, it s not easy to say if these problems are software or hardware related. But I guess that its software.

    I checked your screenshot pic, but I've never seen this error message. But it looks like something wrong with the graphics driver. The message says something, live events of kernel
    The core services are required by other parts of the operating system as for example graphics card driver.

    In this case I recommend updating the graphics driver. According to you, this message an Intel GPU. So you can see the Intel page for the driver for the graphics chip compatible.

    With regard to the key issue of the FN;
    The Toshiba FlashCard utility controls the key features of the FN. I read in this forum that this application does not smoothly run and in some cases it causes some issues. The new update should solve the problems. You should check the Toshiba driver page. The utility of FlashCard is a part of the Toshiba value added package.

    So finally a tip more:
    You should always check the updates of Vista on the Microsoft page. This operating system is not perfect and Microsoft releases hotfixes and patches very often

    I hope that it would help a little.

    If necessary just ask for more information :)

    My ENVY5530 at the age of one month all the in a has problems.  Firstly, it has not feed paper, then a HP Tec, I help and then it worked fine for a few weeks.   Later, same problem returned, paper does not feed, and now, I still have a new problem.  The document is printed, but the top is folded and torn.   However, from time to time, once a page prints perfectly and I am hopeful, but then the mistakes to come immediately.  I reinstalled, but the book looks always up before it feeds through. It is as if it is to be caught by something while it passes through.  Now of course the store (Best Buy) not exchange it because I went over the allocated period of 15 days.  Of course, I thought it was working fine up until 15 days have expired.  The most irritating thing is well, I can't count on it, what problem there at that time?  Maybe tomorrow it will work perfectly again.  Y at - it something I am doing wrong?  Has anyone else encountered this problem with the top of the paper coming out mutilated?  If I can't understand this point I'll have to return under warranty, HP will repair or send me a replacement.  But I would rather by this argument.  Thank you

  • Weird problem with the google search on Safari 9.0.2

    Hi all

    I had a weird problem with Google on Safari recently. After that the search for something from the Google home page and search page is loaded, I can't be able to change or enter anything in the more the google search bar. I have to reload the page every time google to search something else. Google search worked fine on Firefox though.

    I use the latest version of Safari (9.0.2) and I tried clears all history data, and Web site, but nothing has worked so far. My Mac is running on OS X Yosemite so what counts.

    Can someone understand what is the problem?

    Thank you.

    If you have problems to open Web pages, take a look at these techniques proposed by Apple of troubleshooting.

    In addition, a restart may help.

  • Satellite P300 - strange problem with num lock keys

    I had a problem with my keyboard lock num. I have a P300D - 131

    By pressing '4' and '8' at the same time, it shows on the screen '4 '.

    By pressing "0" and "6" at the time, tamed, it shows on the screen "0 0".

    This also happens if I touch the very fast numbers. That's why you can't count on the num lock keys! I have this problem since I bought the laptop in July 2008. Now, I found this forum and I hope that really that someone can help me solve this issue!

    Thank you

    Hello

    These issues in the past have been resolved with BIOS update. I therefore recommend as a first step of the BIOS update.
    Check the current version on your laptop and the most recent proposed on the Toshiba download page.

    To be honest I don't understand why you waited so long on this subject. Laptop warranty valid and the nearest Toshiba authorized maintainer can help you about this.

  • Analog output with counter Falling Edge

    Hi all

    Here's the iamge which describes what wishes to accomplish. I would like to trigger that the AO output with the edge of the fall of the meter.

    I have set the clock for my AO as the counter.

    The analogue output should be raised whenever the Digital signal meter falls
    

    SAMPLE_SIZE = 80
    
SAMPLING_RATE = 40   #Samples are written every 25 milliseconds
    
TIME = float ((SAMPLE_SIZE) / (SAMPLING_RATE))
    

    CREATE TASKS
    
CREATE CHANNELS OF AO
    
CONFIGURE THE TIMING CHANNELS
    
DAQmxCfgSampClkTiming (taskHandleAO, "PFI12", SAMPLING_RATE, DAQmx_Val_Falling, DAQmx_Val_FiniteSamps, SAMPLE_SIZE)
    

    CREATE TASKS
    
CREATE A CHAIN COUNTER
    
# Time high-low + time equals 25 milliseconds and is proportional to the frequency of sampling
    
DAQmxCreateCOPulseChanTime(taskHandleD,"DAQ/ctr0","",DAQmx_Val_Seconds,DAQmx_Val_Low,0.00,0.005,0.020)
    

    # The values of voltage DAQmx writing
    
DAQmxWriteAnalogF64(taskHandleAO,SAMPLE_SIZE,0,10.0,DAQmx_Val_GroupByChannel,Voltage,None,None)
    

    # DAQmx AO task start
    
DAQmxStartTask (taskHandleAO)
    

    # Counter DAQmx Start task
    
DAQmxStartTask (taskHandleD)
    

    #TIME is equal to the total time for the writing samples
    
DAQmxWaitUntilTaskDone (taskHandleD, 2 * TIMES)

    I get an error every time that I run the task:

    DAQError: Over Acquisition or generation has been stopped until the required number of samples were acquired or generated.
    
 function DAQmxStopTask

    That's because my AO task is stopped for some reason any.

    Is there an obvious problem with the code. Can it be structured differently?

    best regards,

    Ravi

    I do all my programming in LabVIEW, so I'm pretty limited to help with programming syntax text.  That being said, here's what I * think * I see:

    Your AO task issues a call to DAQmxCfgSampClkTiming, but is not your task of counter.  This probably leaves you with a meter spot which creates only a single impulse, which causes only a single AO D/A conversion.  In LabVIEW when I need a pulse train, I would call a similar function of the synchronization with the clock mode is defined as 'implied '.

    Hope this helps you get started, I don't know enough to give you the specific syntax in the text.

  • Problems with encoder motor switching noise readings

    Hi all

    I wanted to ask advice with a hardware problem which seems to be pretty common.

    Here I describe my request:

    We are controlling an electric actuator for robotics application. We use encoders to take position readings, and we need to perform analog acquisition for other measures (for example, the force measured using strain gauges).

    The problem is:

    In summary, I have problems to properly acquire position readings of a linear encoders quadrature and also a few analog inputs. The cause is the switching noise generated by the drive motor that we use (which is an engine without Stricker of CC Moog BN-23-23).

    Our acquisition platform is an NI PXI-8106 with a PXI-1042 q chassis. We have two possibilities to acquire the signals. We have a multifunction DAQ series NI PXI-6259 M and a FlexRIO NI PXI-7951R with one module DIO NI PXI-6581R.

    The switching noise have a frequency of 30 kHz. In a scope, we see a series of peaks of noise which are present only during a short period of time (approximately 1/10th of the duration of the noise). The rest of the time the noise is not present.

    The Accelnet amplification module that powers the electric motor gives us a clock signal synchronized with the noise (whose frequency is approximately 1/4 frequency noise). This clock signal provides a way to solve the problem of analog acquisition. We can use this clock to make an acquisition stamped with an external clock in LabView connecting the clock on a spit of PFI or FPGA card. But the noise is also corrupt this clock signal (we get an error daqmx us warning of possible defects in the clock signal and also to stop the acquisition). I believe that to solve the problem of encoder we can also solve the problem of the analog acquisition.

    In the encoder readings noise makes our County to counter upward or backward gradually fast enough. We can get an increase in the position of about 10 cm per second with no appreciable movement in the linear actuator.

    It would be a great help if someone could put the solution he uses to solve this problem.

    Thanks in advance for your help,

    jespestana

    PS: I stress my conviction that we have a hardware problem, because we have only bad readings when the electric motor does not work. I am therefore convinced because we have already done reading encoder and analog with the help of other players, such as hydraulic cylinders. So, I think that it is not a problem with our software (of our LabView VI).

    Hi jespestana,

    I don't know why the noise could be the cause of your encoder can increase more slowly...  However I have a suggestion on the map of the M series (6259):

    M-series cards have a digital filter integrated on the lines of the PFI (see the user manual of M series).  Looks like the noise is a series of 3 ~ US of impulses (1/10 to 1/30 kHz).  Of the available filtering frequencies that you can set on your M series is 6,425 US, which must ignore the impulses (high or low) that are less than 6,425 US. You can configure the digital filtering with a property node DAQmx:

    One caveat is that the driver only allows you to configure the digital filtering for entries counter on M Series devices.  For example, you can use a digital filtering directly on your task of encoder, but not for your sample clock HAVE.  A workaround can be found here, which is to set up a dummy counter job to define the PFI filter for your task to HAVE.  If you use the same PFI line for your encoder and the task to HAVE it, you should be able to just set up the PFI filter through the task of the encoder and worry for the workaround.

    Regarding the RIO Flex, I think that you could implement something similar on the FPGA, but I'm probably not the best person to comment on this subject.  It would be probably a lot more work to use the DAQmx API's built-in filtering.

  • Structure of the event: problem with data transfer

    Hello everyone,

    for three days I'm troubleshooting an issue in LabView with the event structures. I really hope someone can help here, because I can't find anything on the entire WEB.

    I had six groups of equal to a VI entry, each containing five checks enum (among others) where the user can specify some configuration of measurement data. I want the program to do is: to recognize if a any of these enum values has been changed and if yes, then submit the values containing the cluster in a subvi then calculates the wiring and affect the material of the ports. In addition, i need to submit the number of the enum element that was changed, so the program is able to clear the user input in the case of a breach (e.g. If the user sets two entries of enum control 1 meter and 2 Group 1 and then tries to set a third counter of entry to port 3, the program displays a message and deletes third entry as the number of entries of counter is limited to 2 per cluster).

    To resolve this problem, I used a structure of the event with 6 x 5 cases (change of enum value 1 Group 1 Group 1 enum value 2 change... and so on until the change in the value enum 5 Group 6).

    The problem is that if the user changes a value, the event structure reacts and performs the proper case; However VALUES of the cluster, the user changed are not subject to the SECOND time that an event occurs. It is a kind of a situation, "n-1". For example, if all five controls Enum of Group 1 are 'disabled' first and the user sets enum 3 of 'Meter entry', the structure of the event runs but submits the values previous to the Subvi (all enums 'Disabled'). When the user makes the second change, say that enum SWITCH1 to "Analog Input", the structure of the event is running again and passes the values of the FIRST user to the Subvi editing, then the Subvi gets data "enum 3 meter inlet and all other disabled enumerations.

    In easier words: if I have new values on my cluster "Kanal 1" (left side of the screenshot) and run the structure of the event, on the right side to "Kanal 1" indicator, I get the previous values (n-1).

    The structure of my event is in a while loop. If I create a timeout every 10 ms, and a loop of 250 ms the waiting time, I got the 80% chance that the recent changes are transferred to the Subvi correctly, in other cases I have a delay of the 1 step as described above. It seems to be directly based on the time that I specify the while to wait - but I can't explain it and I cannot accept a less than 100% chance to transfer the correct data, nor can I accept delays of a few seconds for each loop run. If I indicate timeout (infinite) get delayed 1-1 step values in all cases.

    When I specify cases of event to react on "all items value change" of the structure of the event behaves properly - but then I can't handle indicate which element has changed, as the CtlRef of output in case of a structure does not specify "enum 1, enum 2..." but only "Group 1".

    Does anyone have a solution to this? It is certainly a problem with the structure of the event, but I can't understand what to change.

    Thank you much in advance,

    Mr. Boiger

    This is because the terminal is read until the structure of the event runs.   Terminal is read, the event structure is waiting for an event.  The change in value.  Business events are running, but the value is the old value.

    Put the terminal inside the event.

    Or, you can display the connector called "New value" on the side left (stretching down from the border of the node 'CtrRef').  Use a wire one to come.
