DAQmx read 1 d or 2d

Attached, I have a 4 channel daqmx read that's nchan 2d - nsample. I can't get the IIR filter works with 2d data. I can operate with 1 d, but this isn't what I wan't. The IIR filter is possible to work with 2d data? The vi works now because I just left the unwired filter.

When I like you suggested, created the constant of waveform and connected it to the queue, everything was fine. It had been difficult for me, but you nailed. Thank you very much.

  • DAQmx read slowly measurement

    I am still fairly new to LabView, only it uses about 5 months, so bear with me.

    I'm trying to understand why the DAQmx playback function runs slower I expect.  I use a PCIe-6363 map connected to two BNC-2110 connector blocks.  I run the attached code (Position AOM control_prod_cons) and producer while the loop takes about 14 ms to execute.  Here's why this is a question:

    The Subvi belongs to a larger structure that we use in our research lab to run our system of construction craft nanofabrication.  You are using a computer-controlled turntable (wise move task), monitors of reading of the scene (spot monitor sensor) sensor and control a shutter that controls power to the sample (Subvi with lightning) laser.  Up to 4 outputs analog and three analog inputs.  The scene is being ordered to move in 5 steps of nanometer to a speed of 50 micrometers per second, a rate of analog output of 10,000 samples per second per channel (3 of them).  The shutter has a rate much more low yield, at most 5 samples per second.  Our goal is to synchronize the movement of the scene with the shutter, and so we must read the exact position of the scene using the analog inputs, one for each axis, x, y and z, vote as often as possible, even if in reality it didn't need to be more than one read each ms.

    AOM control_prod_cons position takes two points in space that we wish to move between two points where the shutter must open/close.  The first image in the flat sequence did some vector calculations to get the line that we write out the origin of the octant where x, y and z be positive by adding or subtracting, then making reflections around axes, if necessary.  The end of x, y and z values (which are now all positive) are summed and placed later in the sequence.  Coordinated sensor monitor are then read in (loop producer) and turn the same way coordinates the target have been transformed (consumer loop), then compared with the values of (x + y + z) end and start (0) and adjusted accordingly shutter. (For troubleshooting purposes, "off" is 2.5 and read the text file we entered to extract structure).

    All the tests I've done so now tell me that the loop of the producer is the rate limiting step.  For a line that is 30 microns long, with the displacement of scene I described above, I was 45 or 46 readings, that works on a read (on the three channels) once all the ~ 14 ms, or only 72 samples per second per channel, which is * very * slow for the card and is not acceptable for our application.  Am I missing something?  Why the producer loop takes 14 ms per iteration?  I tried to reduce the sampling frequency of writing to 1000 samples per second per channel, but that did not alter the reading rate, so I'm not sure I can cela pins on the map.

    I ran the DAQmx read function as a NChannel 1sample, read in a while loop like I do in more complicated VI, reading of the three analog inputs in a very simple VI who only reads the sensor monitors and nothing else and the reading rate was 2750 samples per channel (read 5000 samples through three channels in 1800 ms) , so I know that the card can read that fast.

    I've also attached the highest lying VI that sets up the physical channels for adding information.  I am also attaching a VI where the producer/consumer framework is not used.  Also, this while loop took ~ 14 ms to exploit.

    Sorry, that was so verbose, just try to do what I'm trying to erase.  If you have any other questions, please just ask.  Thanks in advance for your help.

    Well I'll be darn.  The "task AO is?" query seems to be the culprit.  I have no memory of being always aware that there was such an expensive application.  I don't know if I tried to make such a request in a tight loop before, but I'm a little surprised by the fact that I'm surprised.  I don't know if anything is changed, but in case it's a secondary-ish effect, I use the new DAQmx 16.0

    Another approach would be to use a property DAQmx writing node to query the Total number of the samples.  It seems quite a bit faster.

  • What is READ the array returned by the DAQmx meter? How can I know the two functions DAQmx READ data stream in the same WHILE loop?

    I have a question about the order of execution.  In the WHILE loop, I have two things to measure, period and tension using the DAQmx READ functions for voltage and the meter.  In the end, I want to collect these data as points almost simultaneously as possible, as a pair and then send them together to another piece of code (not shown here) which them will result in some sort of command for an engine.  It would be run, and then I want to perceive the tension and the period at a time later and do the same thing.

    (1.) I'm a little confused on what the meter of the READ function is back because it's a table.  What is a picture of?  I thought that it was up to the value of the individual periods between rising edges.  The output of the counter 1 DBL d's a table. How many elements in this table, and what determines the size of this table?  Are the elements of the array the individual delays between the edges?  How many values are stored in the array by executing?   We take the AVERAGE of the last 15 items, but do not know if we are throwing some of the data or what.  How to understand the composition of this painting?  How can I change the composition of this painting?  Is it possible to measure only one period at a time, for example the time between TWO edges?

    2.) Will this WHILE loop execute as it gathers tension and a "period table ' (remains to be understood by me) by TIME running in a loop?  In particular, we want that the value of the tension associated with the value of the AVERAGE of the period "array", so we can use two data items to create orders of next control every time that the two values are reported.  The structure for the delivery of vi will be attached data in pairs like this?  I understand that one of the READING functions run not before the other function of READING in the WHILE loop.  I want that the period "means" and "strain (Volt) collected at the same pace. This vi will he?

    Hi David,

    I suggest including the DAQmx Start Task function. If it does not start before the loop, it starts the loop and work very well, but it is not as fast and efficient. In the model of task status, task wiill go to run the checked each iteration of the loop and then back the time checked running when it restarts.

    I did a quick comparative analysis and it seems that the WFM D 1 is slower and takes more memory than the 2D DBL.  The overall impact of these differences depends on the size of your data blocks.

  • DAQmx Read simultaneous calls on the same digital line

    Hi all

    I use v10.0 LV 32-bit on Windows 7.

    I use DAQmx Read (in a task) to check the value of a digital line. Is it OK to do this in two different locations in a program at the same time for the same digital line? Or I have to put a wrapper around reading to force operations to be sequential?

    When you need to expose the capabilities of resources to multiple areas within a project (expand the scope of a resource) it is common to wrap the resource in an Action engine to encapsulate the resource functions. See here for an example of a 'Module on resources' material and a discussion animated about how this code help development construction and avoid resource conflicts.  If you have not read famous nugget again – he of Ben is a link in my tag "Required_Reading".

  • Error 200088 using the DAQmx reading VI in a case structure

    Main problem: I'm writing a VI that will read data from a data acquisition and write to a text file when I hit a button "registration". To do this, I use the VI of reading DAQmx in a while loop, which is located in a case statement (I hit the 'Save' button for the case of true), which is in another while loop. My DAQmx create Virtual channels screws are outside of the loop, so a wire goes through three structures to connect these screws to the VI DAQmx Read.

    After clicking on 'Save', my VI works until I hit the "Stop" button, how I get error 200088: ' specified is not valid or does not exist. " If anyone can help me get rid of this error, that would be greatly appreciated!

    I enclose my VI and an image of the error.

    Secondary problem: currently, I use two different DAQmx read live: one mentioned above, which lays down: after clicking 'Save' and the other who reads data continuously to display on maps. I want to combine these two, but I don't know if this is possible given the case statement.

    Thank you!

    Hi Alexwright,

    I made some quick changes to demonstrate the producer consumer loop that would be effective in your case. You want to loop of producer in the first while loop so that you use and the same closing DAQmx task. Moving a forwardthis will require some trial and effective change for your application. Please also make sure you use our debugging tools: http://www.ni.com/gettingstarted/labviewbasics/debug.htm.

  • DAQmx reads (or writes) in parallel and series

    Is there a performance difference between putting DAQmx reads (or writes) in parallel or series?

    Well said.  In addition, using series would create dependencies of data flow, so the readings could not happen at the time of the soul, where parallel would remove the dependencies.

  • DAQmx read - the values on the scale or not? Binary conversion.

    Hey everybody,

    I had a question regarding making the scale and the release of Renault. I use LabVIEW 2009 SP1, with a pilot DAQmx 9.0.2 and a X-Series card. I'm reading the data my DAQ and store it in a binary file.

    How is the acquisition of data read samples, in General? that is if I select NSamp NChan I16 2D Analog on my DAQmx Read, what kind of values can I expect if I was at the exit of the probe data? (Suppose I have readings in mV values and my overall fork's 04:55 V.) When he wrote in the binary file, what happens, what can I expect to see in terms of values - or maybe just descriptively?

    Overall, a little insight would be very helpful. I tried to troubleshoot asymmetric readings I received, so this will help me immensely.

    Thank you.

    Hi Matt87,

    Reading data as I16 will return the result adjusted, not calibrated for 16-bit ADC.

    If you want to write your own binaries, you'll want to include scaling of device - for series X, coefficients a 3rd order polynomial.

    Here are two examples that show how write to a binary file and read the data back.  In this example, scaling coefficients are stored in the file header:

    Continuous gain and voltage drop (binary) chart

    Graph of the acquired binary data

    That said, I would recommend that you look in the record feature integrated TDMS introduced in DAQmx 9.0.  The result is a file appropriate binary .tdms which is a standard format that can be opened in LabVIEW or in several other programs with the plugin.  See the following examples for how to use the function:

    Streaming data and log to the PDM file

    Continuously to log in a PDM file data

    The second example does not force you to read the data in the memory of LabVIEW and use the minimum CPU.  The first example allows you to see the data that is acquired.

  • Medium-sized dynamic data analog input read DAQmx read

    Hi, I'm new to labview. Is there an easy way to index using the dynamics of data returned by a readout DAQmx x samples to calculate a moving average? My thought was to read the analog input for X samples pump with the data in another loop through the data, but I can't quite understand how index using the returned data set to extract the measurement value double returned for each sample.

    Any ideas on that?

    Thank you...

    If you get a type of waveform data, why did you ask on dynamic data? No, of course not would you use the conversion of dynamic data on a waveform.

    If you want only one channel, then your DAQmx Read could be changed to 1Chan NSamp. If your channel list only has one channel, you will get a table 1 d with a single element that can be indexed. To get the average of a waveform use the statistical function with the waveform. You use the average Point by Point, and not the average function that has a table for an entry.

    Make sure you always have context-sensitive help on. You can avoid many of these rookie mistakes simple.

  • How .vi DAQmx Read (analog 2D NChan DBL NSamp) to acquire continuous data?

    I try to get the .vi DAQmx Read (analog 2D NChan DBL NSamp) to acquire data continuously.  The 'help' indicates I need to wire the number of samples per channel-1, but it doesn't seem to work for my application.  If I have the wiring to any number greater than 0, the data collection works, but is not continuous.  I enclose the code (Sept15_MainPanel_WorkingBaselines_ApplyBaselines and Calibration.vi) and a Subvi (Collect_Baselines.vi) if someone wants to take a look.

    Here's what I'm trying to do:

    I use a unit NI USB-6009 to collect analog voltages of load cells 2 (channel 0 and channel 1) and 2 displacement transducers (channel 2 and 3).  The main panel of the VI contains a listbox with 4 options - 'Check EMG channel', "Collect base lines," "Collect Data" and "end of program".  'Collect base lines' 'End of program' work and I'm working on writing code to "Collect data".

    For the option "Basic collection", 2500 samples are read from 4 channels described above and 2500 samples are averaged.  This works.

    The option "Data collection" - I would like to that data from 4 channels to acquire permanently.  Finally, for the option of data collection, data acquisition stops when channel 0 detects the force of 200 N - so I will not always have a finite number of samples read.  The time it takes to reach the value of this force will be different for each test.

    -How can I get continuous samples for my 4 channel?  Is .vi DAQmx Read (analog 2D NChan DBL NSamp) function badly and if yes, what should I use?

    Thanks in advance for any ideas or advice.

    First, in case 1, you need not the structure of flat sequence.  The son of the error and data properly will dictate the flow of execution.  Then, in State 2, you must initialize the shift register, unless you want to keep the data is accumulated each time that you run the vi.  The reason why you don't see all the data here is because you have - 1 wired for the number of samples per input channel.  You must connect a number here, even if you are taking continuous samples.  The service needs to know how much sample to gather at one time.  If you put-1 here, the number of samples per channel must be set up in the synchronization function DAQmx (sample clock).  If you specify a number here, then you put-1 in playback function.  The DAQ hardware will read continuously, you must retrieve the data from time to time, so you must specify the number of samples.  By reading inside a loop, it will continue to read until the stop function is encountered.  I guess that the Clear function acts as a stop.  But you must always indicate playback vi how many samples to read and return on each iteration of the loop.

    The documentation is a little misleading.  He warns that a - 1 will cause a continuous reading.  But the pads are so big, he can not read continuously forever without losing data.  If you specify a finite number, playback in a loop, and he will read this number and return the data (empty the internal buffer) at each iteration of the loop.  Continuous means that you just call the start function once.  He will read at each iteration of the loop until the stop function (or clear) is called.

    Here is the difference between the setting of the Timing DAQmx function for continuous or finished reading: finite samples requires a tenure, he reads the finite number of samples, and it's done.  It requires another start to read more data.  Continues to read requires only a start.  It still reads a finite number of samples, but when this is done, you can retrieve the data by calling the read function until he could continue.  After the reading, you don't have to call for new start.  Look at it this way.  Start is what starts the collection of data, not the read function.  Just read empty buffers in your data feed.  The data acquisition continues in continuous mode, but you must call read again to get the data on the pads.  If you specify basically buffer size when you set the number of samples per channel.

    It is important to get the right information in the data file. It is not a lot of overhead to limit your data with a specific precision if you as a table.

  • Problem DAQmx read True False

    Hello

    I use DAQmx Write (Bool digital 1Line 1 point) to send a Boolean sample to a digital output channel.  I want to be able to tell if the signal is strong or weak, so I use DAQmx Read (Bool digital 1Line 1 point) to take up the task as input and then plug a light at the end of data.  The problem is the light lights up when I pass False to the VI DAQmx writing and does not shine when I pass the value true to the writing DAQmx VI.  Shouldn't the DAQMx Read VI be output Boolean even as input to the VI DAQmx writing?  In others, should I not get a true reading VI DAQmx if I pass a real in the DAQmx writing VI and even for a case of false?

    See code attached for simplified example of what I'm trying to do.

    Thank you

    Jason

    Which would make sense if the channel is configured as an open collector output.  This would mean that the line is retrieved when you write a REAL low and left floating when you write a FAKE.

  • I can't stop finite samples daqmx read between the two?

    Hi all

    I want to read data from 10 seconds to a trigger is received. for this im using daqmx task finished sample mode and read the data on the trigger getting. It works fine but I can't stop my vi between the two when its reading of the data. I have to wait for it to complete the reading of values, and then stop the vi.

    so I switched to continuous sampling mode that allowed me to stop the vi whenever I want.

    I just want to know is there any means or the property using which I can stop my task over daqmx read when I want?

    I guess you call DAQmx Read with extraordinary value (-1) for samples of #.  It is also the default if left thread continues.  In a finished sample task, it means to wait until the memory full buffer has been filled with samples before returning.  Once you make that call, you cannot directly finish soon.  You're stuck waiting for buffer fill or for the timeout expires (default 10 seconds).

    One way to avoid getting stuck is not to ask for samples that do not exist already.  You can query a DAQmx Read property, known as the "Samples available" or something like that and son of this result in a call to DAQmx Read.  Such a call will return immediately whatever data are currently available.  Subsequent calls will give you samples.

  • Is it time stamp with daqmx read

    Hi all

    Simple question.  I have currently not creating a task or starting a task, I simply create a channel and reading that chanel.

    It is...  Why I don't get a timestamp when you do and do I create a task to get one of this?

    There is a timestamp when you use the DAQ Assistant or when you choose to return a data type of waveform with DAQmx Read.

    You can't do a reading without a blemish. You don't have to create the task in MAX, however.

Maybe you are looking for
