Reference with 6215 trigger: error 200452

I am trying to create a trigger for reference to the analog inputs of sample. However, I get the following error:

Error DAQmxBase-200452: specified property is not supported by the device or is not applicable to the task.

And here is the code (which is actually from one of the sample codes)

.

Trip parameters
Char [] triggerSource = ' / PFI0/Dev1;
uInt32 triggerSlope = DAQmx_Val_RisingSlope;
uInt32 triggerSamples = 100;
.

.

.

DAQmxErrChk (DAQmxBaseCreateTask("",&taskHandle));
DAQmxErrChk (DAQmxBaseCreateAIVoltageChan(taskHandle,chan,"",DAQmx_Val_Cfg_Default,min,max,DAQmx_Val_Volts,));
DAQmxErrChk (DAQmxBaseCfgSampClkTiming (taskHandle, clockSource, sampleRate, DAQmx_Val_Rising, DAQmx_Val_FiniteSamps, samplesPerChan));

DAQmxErrChk (DAQmxBaseCfgDigEdgeRefTrig (triggerSource, triggerSlope, taskHandle, triggerSamples));

DAQmxErrChk (DAQmxBaseStartTask (taskHandle));
DAQmxErrChk (DAQmxBaseReadAnalogF64(taskHandle,pointsToRead,timeout,DAQmx_Val_GroupByChannel,data,bufferSize,&pointsRead,));

printf ("%d samples\n achievements", pointsRead);

Print only the first 10 points
for (i = 0; i< 10;="">
printf ("data [%d] = %f\n", i, data [i] ");

Reference trigger not taken the 6215? I m using the following:

OpenSuse 11.2

MX NI DAQ base 3.4.0

LabVIEW 10.0

I m basically just make use of the C API in my own program and do not use other software to configure the DAQ.

Unfortunately, reference trigger is only supported in DAQmx Base 3.4 for the PCI, PCIe, PXI M Series (see the DAQmx Base 3.4 readme file).

A possible solution would be to sample lines HAVE continuously and implement the reference trigger yourself in the software.

Best regards

  • Error 200452 with break triggered DI on PCI-6251

    Hey guys,.

    I am writing a program to snoop on SPI communication between a microcontroller and two MAX-7221 display drivers. Essentially, I want to read the PIN Din of both fleas and convert the data stream in the numbers that are displayed on the front panel of devices (each chip controls two 3 figures, 6 total). The data is 16-bit and contains a 4-bit address and a 4-bit code representing the number b. I recognize these two values in the vi, convert code B in decimal and use the address to combine each digit in the corresponding 3-digit numbers that I can view and save to a file.

    Each chip has a Din row that contains data, a clock and a load signal (called CS). In my vi I acquire the data using the remote clock signal and use a trigger break to acquire only when CS is low. It worked perfectly to collect data of a single chip MAX-7221, but I started to run into problems when you try to acquire data of these two channels at the same time.

    Since I am on two different trigger and clock signals, I couldn't use a single data acquisition. I got a PCI-6251 card laying around and decided to use it to develop a single chip and my original USB-6361 to acquire the other. Acquisition data from as chips with the USB-6361 works perfectly, but when I try to acquire two Renault at the same time I get error 200452 associated with the trigger break PCI-6251.

    I did a ton of digging, but I can't seem to understand what the problem is. The Web site OR said that the PCI-6251 supports triggering of break, and any channel I use, I still get the same error. I even tried to use other types of triggers, but no matter what I do error 200452.

    Thoughts?

    Thanks in advance!

    Colin

    It seems that the PCI-6251 card only supports digital break triggering on a similar task. You use it on a digital input task. 6361 USB supports triggering of break on the two types of tasks. That's why you get an error.

  • PXI-6254 trigger external start (error-200452)

    Hello

    I have a PXI-6254, I need to start with an external signal, so it is synced with another device, however, regardless of the source, I say to use as a trigger (a PFI, PXI_Trig or PXI_Star line), LabVIEW tells me "error-200452..." The specified property is not supported by the device or is not applicable to the task. "For example, I'm doing a digital output using the example of 'Write dig Chan - Int Clk - Dig Start.vi'.

    Is it really the case that this device cannot be triggered by an external signal? The manual for this device (http://www.ni.com/pdf/manuals/371291h.pdf) implies that it can be triggered externally, and if it is possible, what I am doing wrong?

    See you soon,.

  • Error 200452 with synchronization of two cards PCI-6733

    LabVIEW: 8.6

    Using two cards PCI-6733 connected via a RTSI cable, I'm trying to get an output synchronized two PCI cards (which are connected to of BNC-2110).

    Here is the labview code I put together by looking at the examples online and in the program. To the left of the diagram is the part of the program that generates the entries.

    Currently, it gives me an error 200452: "specific property is not supported by the device or is not applicable to the task." Property: task of Start.TrigType name: _unnamedTask<26>. »

    Any ideas how to solve this problem? The Labview code above looks like it will do what I want?

    Thank you

    After investigating further the code, since it seems that your referencing the same clock, you do not need a trigger. You can probably avoid the error by removing the third blpck on all threads

    Hello

    I think I misread your original message, and I changed it when you answered. My apologies.

    It looks like all this you want to do is raise an error if someone tries to add a second line "ACTV.
    You better not to use a trigger while: more it can be done with a unique index, LIKE THIS:

    CREATE UNIQUE INDEX     t_bus_cyc_actv
    ON t_bus_cyc ( CASE
                   WHEN  bus_cyc_stat_c ='ACTV'
                   THEN  1
                END
              );
    

    In general, when you have the choice of doing something with a trigger or some other way (such as a constraint or an index), then the other way is almost always better. Etbin statement "triggers are evil" is perhaps a little exaggerated, but it is something short and catchy to remember.

    The error you are getting now is that a FOR EACH ROW trigger on t_bus_cyc cannot reference t_bus_cyc himself.
    The link I posted shows different ways to get around that. As Peter says, none of them are really the best solution for your problem.

  • Can I use data value references with a functional overall?

    Can I use data value references with a functional global?  I am trying, but it causes problems:  I run the attached VI with "new DVR" selected.  Then I run it again with "return array" and I get the error 1556: "The reference is invalid. This error might occur because the reference has been deleted."  It seems to have forgotten the DVR, but I thought it should be stored in the shift register.
    
    Another odd thing:  In my VI, if I try to connect the wire shown in "something strange", then the type changes (from U16 array to DBL), i.e. it doesn't recognize the type referenced by the DVR.
    
    I want to pass a very large 4-dimensional array between parallel loops with a functional global.  To avoid memory problems, I want to use a DVR and in-place element structures.  If that's not allowed in Labview, I will try passing it through a user event or notifier.  Any problems with those alternatives?
    
    Thanks.
    

    I received a response from an engineer applications OR on this subject, and it seems that it is perhaps a problem with Labview.  They are working on it, so I'll go ahead and close this discussion.

  • Generate tension with a trigger set

    Hello world

    I want to ask a general question on the data generation process.

    I used "DAQmx start digital dashboard" to set up the task to start generating power on a front descended from a digital signal in my application.  My trigger is a train of pulses with a trigger freqeuncy 10 Hz. The build process stops on the front? Or it's just efficient when the first impulse appears and then the signal is generated constantly?

    Thank you!

    haiyueli,

    With a trigger DAQmx start Digital Edge, you will begin your generation when the trigger condition is met (in the case of the falling edge). It will not stop on the front. He will continue to run until it stops in the task, either you stop or a finished generation.

    What you reference looks more like a break (example).

    OK, the problem is: the table "voy" means "stay" and "quarto" means "room". I must, before inserting it on 'Hotel', to check whether or not this room is available.

    I can do this:

    insert into voy values (4, 3, * 3 *, to_date ('09.12.15', 'yy.mm.dd'), to_date ('10.02.25', 'yy.mm.dd'));

    But if, after this command, I do this:

    insert into voy values (5, 4, * 3 *, to_date ('09.12.15', 'yy.mm.dd'), to_date ('10.02.25', 'yy.mm.dd'));

    He accepts and he shouldn't, because I put 3 and 4 users in the same room at the same time.

    the 3rd field is the id of the room, and the two fields are the date of entry (data_entrada) and (data_saida) release date. If a piece is linked to a specific residence in which the release date has not disappeared by, this room should not be available. In addition, the release date can be null, which means that the release date is unknown.

    I hope I was clear on my question.

    Thanks, Chiapa

    I have not yet tested, but this should do:

    CREATE OR REPLACE TRIGGER valida_estadia
    BEFORE INSERT ON estadia
    FOR EACH ROW
    DECLARE
    quarto NUMBER;
    
    BEGIN
     SELECT COUNT(1)
     INTO quarto
     FROM estadia
     WHERE id_quarto = :new.id_quarto and
     (data_saida > :new.data_entrada or
     data_saida IS NULL);
    
     IF quarto > 0 THEN
       RAISE_APPLICATION_ERROR(-20001,'There is already a user in the room.');
     END IF;
    END valida_estadia;
    /

  • Access to the number of property may not set through a reference with static type...

    Hi all!

    I encounter this problem today... Take a look at the code:

    import com.trick7.effects.TeraFire;

    for (var j: uint = 0; j < 10; j ++) {}

    var fire: TeraFire = new TeraFire();

    Fire.x = j * 40 + 20;

    Fire.y = 100;

    Fire.Number = j; This line is causeing the problem

    addChild (fire);

    fire.buttonMode = true;

    }

    Class TeraFire creates fire particles. Compiler error is:

    Scene 1, Layer 'layer 1', frame 1, line 7.1119: access of the number of property may not set through a reference with static type com.trick7.effects:TeraFire.

    Can someone help me find a solution to this problem.

    I can do this 'number' with a clip, but not in this case. What can I do?

    Sorry oops misspelling... I meant fire ['number'] = j;

    The class must also be dynamic for this work, i.e.:

    public dynamic class TeraFire extends MovieClip
    

    (a dynamic class extension is not the class dynamic sub...)

  • Peopleimages property possibly access not defined through a reference with static type class.

    Hello

    I have a custom MXML component called SeeElement.mxml, within this file I defined a VBOX as shown

    SeeElement.mxml

    < mx:VBox id = 'personimages' >
    < mx:Label id = "viewname" / >
    < / mx:VBox >

    Now inside another ActionScript file, I try to make visible to false, as shown:
    SeeElement. peopleimages.visible = false;

    I am thie error

    Peopleimages property possibly access not defined through a reference with static type class.

    Please help me solve this problem.

    Thank you.

    inside your "a few other sctionscript the file' you need a reference to the SeeElement object

    var seeElement:SeeElement = new SeeElement();

    Then you can seeElement.personImages.visible = false;

    SeeElement (with a capital S) refers to the class SeeElement and personImages is not a class member variable its an instance member variable
