Daq device questions

Hi:
I need to syncronize AO and DO on a DAQ device.
I am thinking about USB-63XX series (for example USB-6341.), which has clocked DO, and probably cheaper than PCI series.
I have checked this example : http://digital.ni.com/public.nsf/allkb/EBD603683446EC13862575B3006A63A2 , which makes DO's clock to be AO's sampling clock.
(the website shows that example is for PCI-series)
What I am not sure is, is this kind of shared clocks supported by most of the DAQ device with clocked digital output?
Many thanks

Hi js777,
You are referring to sample clock synchronisation as mentioned in the article in your post. This type of synchronisation is supported on most types of DAQ devices. Please refer to the following links for a list of the NI DAQ models that support this form of synchronisation:
http://zone.ni.com/reference/en-XX/help/370466V-01/mxdevconsid/synchronmxsc/
http://zone.ni.com/reference/en-XX/help/370466V-01/mxdevconsid/synchrone/
Please note that as mentioned in here: http://zone.ni.com/reference/en-XX/help/370466V-01/mxcncpts/syncsampleclock/ this form of synchronisation can result in jitter when used with multiplexed DAQ devices.

Programatically delete a DAQ device

I have created a system with hardware (a USB DAQ) and software that is to be installed on multiple computers overseas. I want to make the set-up as easy as possible because I don't think the people doing the setup will be very well trained, and I won't be there to fix any problems. I have created an installer that includes all the hardware as well as software setup, but there is one issue left, and I'm not sure what the best way to solve it. If the installer is run before the DAQ is connected, then the installer creates a virtual device. If the DAQ is then connected, it is named Dev1, which doesn't work with any of my tasks, of course. I have some code that runs, and verifies the hardware set-up each time the system is started, so I can see if the device with the proper name is virtual, and if so, I can rename the actual and virtual DAQ device to the right names, so my tasks operate properly. However, I now have a virtual device hanging out on my system doing nothing, which I would like to avoid, because there is an outside chance that I will end up on the phone trying to explain to people how to straighten out a system when it goes bad, and I want to keep it as simple as possible. I have two questions:
Is there some way to delete the virtual device programatically?
Is there some better approach to accomplish what I am trying to do? I thought about not allowing the installer to proceed if there is no DAQ device plugged in, but I don't know if that is possible.

I would tend to agree with John_P1's quote below:

I honestly just build up my tasks programmatically.... You can do just about anything that you could do in MAX programmatically via the System Configuration API.
And I would tend to shy away from:

once going into production. MAX tends to be a good tool for getting your feet wet after unboxing the hardware, but something you gradually migrate away from after the prototyping phase -- yet occasionally return to, as you mention, if you need to back up to square one for new prototyping or as a sanity check.
It's possible to deploy NCE hardware behavior configurations, but not necessarily desirable. For the same reason it's possible to deploy any arbitrary configuration (INI, XML, ....), yet it's likely more desirable to build this configuration programmatically -- perhaps persisting it to disk if it's a user-modify-able configuration, or if it's desirable to persist user settings between subsequent deployments -- else it might be most desirable to keep the "configuration" hard-coded as essential business logic (as DAQ tasks might tend to be).
Though, it sounds like you have a solution, and that's far more valuable than more work! Keep a tally on whether the current deployment strategy keeps you and your end users happy, and if so, keep it! Else, consider John_P1's advice, which is more likely to scale with your application if things get hairy.

How to set the sampling interval using DAQ device?

Now I have a capacity sensor and a 24 bit DAQ device (http://www.mccdaq.com/usb-data-acquisition/USB-2404-10.aspx).
The DAQ device has the maximum sampling rate of 50kS/s . My question is how to set the interval of data collection. For example, if I set the sampling rate to 2000, in continuous sampling mode, I use DAQmx read.vi in a while loop and set the 'number of samples per channel' to 100. I want to plot these data as a function of time by using a XY graph and also save these data. So I add a 'Mean' function to get the average of the 100 samples per each loop (than means, there are 20 data output per second). But when I set the 'number of samples per channel' much smaller (to get more data per second), there are some problems. It seems that the program cannot read so many data and get the average at a higher frequency. I don't know where the problem is. All in all, how to collect data more frequently?Maybe I didn't express my question clearly. I'll upload a simple program later if necessary. Thanks.
Solved!
Go to Solution.

Another question is in continuous mode, NI DAQmx uses Samples per channel to determine the buffer size. But according to the website you specified, it says if the acquisition is continuous (sample mode on the DAQmx Timing.vi is set to Continuous Samples), NI-DAQmx will allocate a buffer according to the following table. And for sample rate between 100 - 10,000 S/s, the buffer size is 10 kS. So if I set the sample rate to be 5000 S/s, and set the Samples per channel to be 20000, then what exactly the buffer size is? 20 kS or 10 kS?
Thanks.

DAQ device for linear encoder & labview 7.0

Ok, I am in a bit of a bind, so the quicker the response the better =). I currently have Labview 7.0, and am needing to read the pulses of a MicroE hi-res encoder. I know I am in need of a DAQ device, so I just want to know which one would be the best (cost-effective & easy to manipulate with Labview). Also, I need three analog inputs as well. Preferably the range of the analog inputs would be 0-10 volts (well, preferably 0-10mv, but that is unikely). I am very unfamiliar with programming Labview, but will learn what I need .
Thank you VERY much!

Hello heepofajeep,
I would highly recommend you go with an M-Series Mulitfunciton DAQ Device for this application. The two counter channels on these devices have expanded support for two phase relative linear and angular encoders, compared to older E Series devices. In addition, these devices are capable of performing analog input, analog output, and digital I/O operations. They contain a minimum of 16 analog input lines, with a programmable gain amplifier that will allow you to programmatically set the range anywhere as large as +/-10V to +/-0.1V in order to take full advantage of the resolution of the ADC on the device. These devices can be programmed in LabVIEW 7.0 or later with the NI-DAQmx driver, and there is the DAQ Assistant and many great example programs for getting up and running with your application quickly.
I hope this information helps and let us know if you have any further questions.

Which usb DAQ device to buy ?

I am a total Noob when it comes to DAQ so please bear with me and help me with suggestiions on which NI USB DAQ to buy. I am biochemist and I have an old HPLC machine (basically a chemical purifying/seperation machine) I need to control by writing a labview program. I have labview 2013 and have some basic familiarity with it, and have used very easy VIs like blinking LEDs using arduino interface.
My current project needs me to:
1) control the flow rates on two pumps using their remote controller and vary their flow rates by varying voltages (0-10V) at not higher than 3 mA input current. basically, I need to be able to vary voltages on two analog pins. I am attaching the manual for the pump for more info. The pinout on the remote controller is on page 16/17 of the manual.
2) I need to read analog voltage outputs from these two pumps (which measures the hydrostatic pressure) and save it to something like in .csv file.
3) lastly, I need to read a analog output from a UV detector which will be in mV range and plot it and/or save that to .csv file .
There are a bunch of NI DAQ USB devices which seems like they can do this job, my problem is that dont know enough to reliably make a judgement on which one to buy for this project. My budget is limited and I would definately like to do it with as cheap a DAQ as possible since we have multiple instruments like this, and we are planning to get rid of ancient 1990s computers running the original software and replace it with a USB DAQ device coupled with a labview program on a modern PC. The HPLC machines are far apart hence we run them on individual PCs instead of running a bunch on one computer through a DAQ device.
I know its a whole bunch of questions, but I'll be glad for any guidance on this. also, to do the things I just described, how difficult do you guys think the VI would be if I use a NI DAQ and hopefully dont have any driver/communication issues.

Trying to add a DAQ device to NI-DAQ without hardware

I am developing software for a DAQCard1200 on Windows 2000. I develop most of my software on a system without the actual hardware installed. Since the NI-DAQ dll will error on load under Microsoft C++ unless you have a device configued, I used to configure a device manualy on the development system under NI-DAQ.
I am trying to use the latest version of NI-DAQ (6.9). I cannot seem to add a DAQ device unless I actually have the hardware installed.
How can I work around this to add a device without the hardware or how can I get the dll to load without a device configured?

I am not sure how to add any DAQ devices to MAX. When I right click Devices & Interfaces, I only get a list of SCXI, PXI and VXI devices/chassis. Is there another way of adding devices or expanding the list?

Sending a signal to 1 of 2 different pins on a DAQ device

I am trying to make a VI that simply sends a digital signal to 1 of 2 pins on my DAQ device. Is there an easier way to differenciate between the two pins then using two different virtual channels?

Without NI DAQ device- how to get data from MSP into labVIEW and process it

Hi,
I do not have an NI DAQ device. I have an MSP430 and my sensor is an ADXL335 Accelerometer. How do I get data from my MSP into labVIEW and process it?
Just looking for a nudge in the right direction. I'm having a hard time finding resources on labVIEW that don't involve NI specific DAQs.
Thanks in advance,
Aziz

There are many ways to get data into LabVIEW that do not involve NI-DAQ devices.
I think your easiest option would be to stream it via serial port if the data rate isn't too fast.

PXI 7344 motion controller as a DAQ device for ELVIS

Hi,
Is there a way to reconfigure a PXI-7344 motion controller with its two 68-pin connectors so as to use it as a DAQ device that would receive the signals from a NI ELVIS workstation. The 7344 has a "motion I/O connector" and a "digital I/O connector". Analog outputs are even possible if I remember well, as well as digital.
Thanks

Hello,
The card does has some analog input and outputs. I would check the manual here: http://www.ni.com/pdf/manuals/370838b.pdf. The DAQmx API with a DAQ card is going to be much better than interfacing with a motion card, but you should be able to read off it at the least.

Command or Query to list all connected DAQ devices

Hi,
I am looking for a simple query or function in labview to scan for connected DAQ devices and list them.
Example: With VISA drivers, there is a function "find resources" when passed appropriate query string will return with the list of Ports (or devices connected).
Is there any similar command that can be used for connected DAQ devices? I can look in MAX and see all devices connected under "NI-DAQmx Devices". However, my aim is to get that list in Labview via a query or function.
your input is appreciated.
Thanks,
SS

You use a couple of DAQmx property nodes.

Hi,
There is no option to simulate traditional device.You need hardware for that so i would suggest to simulate a PXI device which has similar configuration to PCI-6014 and to do a small modification to your application..

Can I use a NI 6009 DAQ device to act as a switch to close a circuit?

Can I use (and how do I do it)a NI 6009 DAQ Device as a swith to close a ciruit?

You can't use the 6009 as a switch. You can use the DIO to control a switch (like a FET or transitor). How you would do this really depends on your application.

Which simulated DAQ device would give a value 0 - 50?

Which simulated DAQ device would give a value between 0 - 50? I am trying to run LabVIEW Basics I course project (weather station) by simulating a DAQ device in MAX. (The no hardware version works fine, but I want to use MAX to help it run with a DAQ simulated device). The simulated devices have a range to -10 to 10 volts, while the DAQ Assistant expects a value between 0 - 50. Which DAQ device can solve this problem in MAX? I don't want to alter the VI's. Any suggestions?

The example you are referring is using a scale to do this. The transducer for the example in the course creates a voltage between 0-1V which is V * 100 = Degree Celsius.
If you include such a scale (modify it since the simulated devices do not create a "stable" voltage between 0..1V), you will get something useful for you.
hope this helps,

Analog measurement WITHOUT DAQ device

Hello everyone,
I have an analog voltage which is varying between -10volts to +10volts. Is it possible to measure this analog voltage using LabVIEW software without DAQ ? If not kindly suggest the options available for DAQ device.
In the traditional interfacing techniques which uses parallel port and/or serial port. We can acquire signal using C language and inport and outport commands.And no DAQ is required.... I was hoping if LabVIEW can be used without a DAQ device.
I know that RS232 and parallel port can be used but how will the space and mark levels be used for acquiring an analog signals.

Hello Miaa,from your description I can think about two things,that remind me the days when there where no sound cards
at all computers,but people found the ways to produce sound from PC:
    1)
             Output: you can get from your LPT 8 bit analog output if you connect all 8 data pins to one.
             Input: it probably possible to get 8 bit input,but you need to use some resistors,and have some knoledge in electronics,
                         in order not to burn your LPT with 10 volt input.
           Again,it's possible but not trivial way.
   2)    In general (very): one can get "analog output" even from 1 bit connection,
           in order to do it, the connection speed should be fast enought,and the illusion of "anlog output" reached by changing
        the ON/OFF state of the connection,in right way (playing with delays between ON/OFF,according to signal).
          About "anlog input" using serial port I can say nothing.
In any case,this is very intersting but time cossuming issue,but if you know how to do it,the LabView part is not a problem,
you have there access to parallel and serial ports.

how do i detect DAQ device number programatticaly using Visual Basic (not using MAX)?

Several of the CWDAQ objects have Device (the device number), DeviceName, and DeviceType properties that I think will give you the information that you're looking for. For more information, look in the index of the Measurement Studio reference for Device, DeviceName, and DeviceType.
