Values of generated amount

Hello!

I built a VI that is supposed to calculate the total number of revolutions to an engine rotation. I have a button that controls the speed of ROTATION of the motor and a clock which calculates present.
The problem I have is that I can not understand how summerise the values of the revolution. Say I put my button at 3000 rpm and the time is over for 60 seconds then my flag shows 3000 rounds, but if I change the button to zero, it displays zero revolutions.

I would show him the current revolutions and even if I reduce or stop the engine.

I tried to set up a registry to offset and table to build, but I can't make it work.

Greetings Maurlind!

Maurlind,

When you have the current value, previous situations of value, think that registers at offset. The current value is connected to the right Terminal, and the previous value is available to the left Terminal.

Your VI has a registry change that holds [i] rev and Rev [i-1]. Adding a shift register for t [i] and [i-1] t and some calculations will give you what you need. You can either initialize all the shift registers via the structure of the case and First Call? or by cables to the terminals on the left out of the loop as you did with the revolutions.

Place the labels next to the son showing the symbolic values on the wires. This can help you visualize the relationship between the algorithm as I expressed in my previous post and LabVIEW code.

You can get some benefits of working through the tutorials online for LabVIEW can help you with the differences with other programming languages.

Try to implement what I have proposed. The image above shows part of the changes that I made to your VI which seems to correctly determine the revolutions.  If you get stuck, post your last attempt, so we can help you learn.

  • How to use DBMS_RANDOM. VALUE to generate the specific numbers

    Hello

    I need generate numbers that are only in '120, 121, 130, 155, 198. Would it not possible to use DBMS_RANDOM. VALUE to do and how?

    Something like this:

    WITH my_values AS (SELECT '120,121,130,155,198' AS ST FROM DUAL)
        SELECT SUBSTR (my_values.st, TRUNC (DBMS_RANDOM.VALUE (0, 4.999)) * 4 + 1, 3)
          FROM my_values
    CONNECT BY LEVEL <= 10;
    

    Basically, you need a way to use the DBMS_RANDOM to choose which item of a list that you want. But you can't use DBMS_RANDOM to generate the list items themselves.

  • [Disposal] values not generated after the default of Consolidation in HFM

    Hi all

    I'll put up my applications using default consolidation intercompany transactions and rules of elimination; but I do not see members [removal] is met. The account of the form does not appear unlike intercompany balances. Since I'm on default consolidation & elimination I suspect it must be a problem in the configuration of metadata.

    Configuration of account: Two put accounts in place for transactions intercompany-SalesInterCo & PurchasesInterCo; and one account as PlugAccount-PlugSales

    -SalesInterCo (type of income, yes marked PKI with plugaccount as PlugSales, upper limb PKI [PKI entities], custom1top as BU_TOT Member, custom remains as [none])

    -PurchasesInterCo (type of expense, marked Yes for PIC with plugaccount as PlugSales, ICP upper limb [PKI entities], Member of the custom1top like BU_TOT, custom remains as [none])

    -PlugSales (marked No. for PIC, is calculated - Yes, IMember superior CP [PKI entities], custom1top as BU_TOT, Member custom remains as [none])

    Hierarchy of entities- All basic features have active IsICP and currency as default EUR C935 parent entity default currency USD.

    Hi all

    There was a stupid mistake. -SalesInterCo and PurchasesInterCo - accounts have not enabled for Consolidation. In addition, property of The ICP_Top member on behalf of plug-PlugSlaes - went under [ICP_Entities] [ICP None].

    After these changes and redploying enforcement, I made a 'Contribution to calculate the Force' and ' consolidate all data "at the parent level. Now, I am able to see all the numbers correctly.

  • Number of days where the value &gt; a certain amount

    Hello

    I have a table named named MSR_3423:

    Capture.JPG

    I want to count the number of days where the VALID_VALUE is > to 0.001

    I made this request, but it gives me that result a count of every time that this value has been found in a day:

    select trunc(valid_date), count(*) from MSR_3423 
    where raw_value > 0.001
    and   VALID_DATE IS NOT NULL
    group by trunc(VALID_DATE)
    order by 1
    

    It gives me this result:

    Capture.JPG

    But I want the number of days when this value has been reached. In this example, the result should be: 5 (for 5 days)

    I think there must be a dower to do, but I'm not experienced enough to achieve this goal. Could you help her?

    Thank you.

    You almost have it. Just put another county around your account.

    select count(*) from (
    
      select trunc(valid_date), count(*)
      from MSR_3423
      where raw_value > 0.001
      and  VALID_DATE IS NOT NULL
      group by trunc(VALID_DATE)
    );
    

    or shorter but sometimes confusing

    
      select count(count(*))
      from MSR_3423
      where raw_value > 0.001
      and  VALID_DATE IS NOT NULL
      group by trunc(VALID_DATE) ;
    

    Logic of Alvertos did the same thing. He's just using SEPARATE instead of GROUP BY. But since I do not SEPARATE, I wanted to show a different way.

  • HP Envy x 360 15-aq000nb QWERTY: azerty keyboard driver bug for <>------generating ctrl instead of mapping

    "Nine" HP Envy x 360 with Belgian azerty keyboard

    2 right of the space bar, marked as <>key positions-generates these values, but generates the code for the CTRL key instead.

    This may be a virus or other problem, because it is a new system "comes out of the box". I really suspect of a "Bug" here to test available for this particular model azerty

    The keyboard driver is standard supplied with the operating system of microsoft, called "Belgian Azerty comma.

    The operating system is on the last patch level

    HP drivers are on the last patch level

    I guess it must be declared as 'a problem' and not an 'incident '.

    An update on this:

    The keyboard permanently sends the keyvalue 'CTRL RIGHT'. I wouldn't not because in the majority of keyboard layouts, the button to the right of the "ALT GR" is indeed the RIGHT CTRL. But not on this Belgian AZERTY keyboard. He the key on this post is marked > <------(you access the backslash pressing alt gr with the key, you access the > organizing the passage)

    So I guess it's a problem of HP and a defect of product in a lot of these PC.

    I used after derivation of the to solve for me (but I guess there is still a bug for HP):

    Using the free software SharpKeys. http://SharpKeys.codeplex.com/
    I remapped in the registry (E0_1D) right CTRL key 0 x 0056 (00_56)

    This solved it for me.

    Hope that HP takes knowledge to check if there is a production fault in this batch of HP envy

    On the configuration of the stage for DAQmx generate analog output, there is a field "value to write.  I can't find any explanation for what it is, how it determines the value to enter, nor what he writes.  I am trying to go through the tutorials and it cling.

    Someone would give an explanation?

    Hello

    To write value specifies the value to write in the channels, lines or ports selected in string parameters. In other words, this value will be the value of your DC output (for example if you enter 5, your output will be 5V). To get information on different fields in SignalExpress, access help"context-sensitive help. A pane will appear in your work environment that displays the coordinates of the field when you place your pointer over them.

    For new users of SignalExpress:

    Generation of DC signals with NI DAQmx devices: step in the DAQmx build, select 1 sample (on request) in the generation Mode dropdown. You can select a programmatic input to generate, or you can remove the check mark from the check box use programmatic input and specify a value for generating in the field of value to write .

  • PXI-4461 generate voltage update

    Hello

    When you try to run the sample Daqmx VI "Gen - Update.vi of tension" with an NI PXI-4461, I get the following error:

    200758 error:

    "Type of sample Timing is set to on demand that is not supported for analog output on this unit"

    What does that mean?

    Is there another way to generate a constant DC signal with the 4461?

    Also - for next time that consider us to buy a new card - where can I get information on DAQmx properties (like this one) are supported for each camera?

    Thank you

    Ran

    Hi Ran,

    The 4461 NOR supports HAVE no single-point / AO of because it is based on delta-sigma converters a/n/CED, which require a clock free run at a constant speed.

    There are two ways to output a signal DC with an NI 4461 (or NI 4431):

    1. Continuously to generate a waveform to DC (containing several repeated values).
    2. Set channels DAQmx > AO. IdleOutputBehavior to "Maintain the existing value" can generate several updates.

    The help of LabVIEW has a page of "properties of the NI PXI-4461 supported", but it does list all the supported values for each property for each device. NOR-DAQmx help has a page entitled "Considerations for DSA timing devices" that talks on this subject:

    "

    Considerations of timetable for DSA devices

    Supported sampling frequencies

    Unlike some other devices DAQmx, DSA devices have a maximum and a minimum sampling frequency. Check your device specifications determine the range of sampling frequency.

    Other considerations of DSA calendar

    DSA devices do not support the type of synchronization on demand. All acquisitions of DSA and generations require hardware timing of a stable clock.

    DSA devices do not support external synchronization sources of arbitrary external signals such as tachometers and encoders. PFI lines on the DSA hardware can accept external clocks. You can program a DSA device to use an external clock only when it is a slave in several synchronized system device. Refer to synchronization of the DSA for more details.

  • 6534 PCI for digital output finished generates a continuous output

    Hello

    I use 6534 PCI for my application, where I generate a digital output, a model finished variable length in a continuous loop.  the code runs without error, but I'm not able to justify the behavior of the map. I intend to use the code inside the while loop as a Subvi and if I change the 'command' at the entrance table during each call to the Subvi, the output should vary according to the directives of the entry of the 1 d array.

    But this is not the case, the loop displays the previous value that has been given to Scripture DAQmx. If the control panel is changed the output instantly does not change. It takes a while before the actual output changes. The length of the array command I give is also 88 & 133. When I realize that the output is wrong, I disable the DAQmx write vi by a structure of the case, I would expect an error that the output buffer is empty, but rather the old value is generated whenever the start Daqmx vi task is exectuted without.

    My tax any problem is that the output buffer is not get replaced with the new value, but I'm specifyng the size of buffer, performing a registration every time and start the task, waiting until the task is done and the task stop. Each stop & writing should delete and empty the buffer, but I did not understad what goes wrong.

    Also, I thought that maybe that orders are put in queue up in the output buffer, acual generation is not as fast as the call of the DAQmx write & start, but if that's the case then even if I stop the vi the generation should be until the buffer is empty, but that doent happen VI, break breaks of generation. the number of iterations is equal to the generated models. If anyone can help as to what could be the problem?  find code attached below.

    Hello

    If I understand the problem you are experiencing, then the reason for the typical behavior when you run the VI, it is that you are not clearing the DAQmx task whenever you intend to go for a fresh DIO write. You stop just the DAQmx task that seems however to clear the buffer on board space.

    With this post, I am enclosing a VI of the sample that should work according to your expected behavior. You can even call this VI as a Subvi and can use it to update the DIO port with a digital model of variable length fees. Another fact that I would like to point out, is that, once you have initalised one table, it is not possible to reduce the length of the array. You can only increase by adding new elements. According to your needs given that the digital model that needs to be updated will be of variable length, each time you cll the Subvi, you must create a freash of appropriate length and feed it as input to the Sub - VI. Inside the Subvi, according to the length of this array of entry appropriate buffer space is allocated.

    Do trust this solution help solve you the problem, otherwise do not hesitate to go back.

    Hey "zoomok,"

    Large - an example would have been my next request in any case I took a glance and changed your demo page to work as you want.

    Things of note:

    -SQL source tree: NO link value! A link value will generate apex code that will redirect you to the link. It will always be a redirect page, where a rerender page, and not what you want! Leaving NULL allows us to interact with the tree interactively via javascript

    -Code in variables and functions global page - javascript - next:

    function treeOnload(){
      var l$Tree = $("#tree_modal div.tree"); // get the tree instance
      // handle the onselect event of the tree
      $.tree.reference(l$Tree).settings.callback.onselect = function(NODE, TREE_OBJ){
        $s( "P112_CAT_CD", $(NODE).attr('id') ); // get the VALUE of the node and put it in item P112_CAT_CD
        closeModal(); // close the active modal region
      };
    };
    

    -In javascript - dependent section I added a call to this procedure:

    treeOnload(); // initialize the tree with our settings
    

    And that's all! I didn't know that you use "openModal". There are different ways to implement modal regions, so it is important to know how we do for ourselves what to do with it.

    FYI - you now need to change your credentials. And mark the answer that has helped you or is correct, please.
