CompactDAQ using to acquire correlated data force-position began with a trigger of digital material?

Hello

up to now, I use a PCI NI6221 card to acquire the data of time - correlation of two analog inputs and an encoder (line A and B), i.e. to get two supply voltages and position for each sample. The beginning of the acquisition is hardware-triggered by a digital line of PFI.

In addition to assessing the encoder inverted /A lines and / b (to eliminate the errors of counting in harsh environments) I want to migrate this task to a CompactDAQ 9172 module with a 9205 (for analog), a 9411 (for incremental encoder signals) and a 9472 (for outputs digital additional static) inside.

My question: is it possible to use the entry PFI0 of the 9205 as trigger of digital material to make an acquisition described above? Or how should I continue?

Best regards

cpschnuffel

I would like to make a correction to my last post... we have actually supported for triggers the 9205 (analog and digital) to any location in the 9172.  Digital lines has always obey the same rules I mentioned earlier.

So, you can trigger off the 9205 PFI line in any location, or outside either module in slot 5 or 6.

I'll be sure to amend article KnowledBase that I've referenced once I have the chance to make it clearer and more thorough.

  • How can I use notifications to send data from different sources for the same chart?

    Hello

    I use the model of 'Continuous measurement and logging' project comes with LV 2013.

    It is extremenly helpful in understanding the messaging between the acquisition, graphic and loops of newspaper. (Thank you NEITHER!)

    I ran into a snag though.

    I want to change so that my graphic loop receives notifications of data from two sources of acquisition by the declarant.

    I have trouble getting the data from the two sources to display on one graph.

    I've isolated the problem in the attached vi.

    Here's what happens:

    1. I create 2 parallel loops data and send the data to a third parallel loop with the notifiers.

    2. the third loop receives data from one of the loops because one of the authors of just receiving notifications is to expire instead of receive data.

    Can anyone suggest how can I fix?

    Thank you.

    -Matt

    Here's my modification of your VI. I put notes on the block diagram to explain the changes. He uses a queue for data transfer to avoid data loss. It uses a notifier to stop loops. All local variables and value property nodes have been eliminated.

    The way loops are arrested probably let some data in the queue. No more of one or two iterations of each of the loops of data acquisition. If you need ensure that all data has been displayed (or recorded in a real application), then you must stop acquiring loop first and read the queue until you know it's empty and both other loops stopped. Then stop the render loop and release the queue and the notifier.

  • How can I use internal clock case OR USB - 6259 BNC for the acquisition of digital data in my own big software?

    I want to integrate the ANSI C sample program ReadDigPort - ExtClk.c in my own big package.

    I want to use the internal clock of the BNC NI USB-6259 (.. 80 kHz 120 kHz).

    In the document:
    High speed M: Series Multifunction DAQ for USB - 16-bit, up to 1.25 MECH built-in BNC connectivity. / s,.
    is written:
    Or sample DI source clock: Any PFI, RTSI, HAVE sample or convert clock, AO, Ctr n out internal and many other signals sample clock
    The digital subsystem doesn't have its own dedicated internal synchronization engine. Therefore, a sample clock must be provided another subsystem on the device or from an external source.

    How can I use internal clock case OR USB - 6259 BNC for the acquisition of digital data in my own big software?
    With what other subsystem on the device can generate a source of the clock? How?

    It is possible to set a clock on an internal counter (for example ' Dev1/ctr0"):
    Creates channels to generate digital impulses that define the freq and dutyCycle and adds the channel of the task that you specify with taskHandle.
    DAQmxCreateCOPulseChanFreq (taskHandle, "Dev1/ctr0" units, clockName, idleState,
    initialDelay, freq, the duty cycle); works

    But it is not possible to drive this internal clock to a terminal (for example "/ PFI0/Dev1"):
    DAQmxErrChk (DAQmxCreateCOPulseChanFreq (taskHandle, "/ PFI0/Dev1", clockName, units, idleState, '))
    initialDelay, freq, the duty cycle); does not work: error DAQmx: measurements: type I/O of the physical channel does not match the type of I/O required for the virtual channel you create. Name of the physical channel: PFI0. Name of the virtual channel: clock

    The sample clock source can be derived from an external terminal (for example "/ PFI0/Dev1"):
    Sets the source of the sample clock, the sample clock rate and the number of samples to acquire or generate.
    DAQmxCfgSampClkTiming (taskHandle, "/ PFI0/Dev1", maximumExpectedSamplingRate, DAQmx_Val_Rising, ")
    DAQmx_Val_ContSamps, bufferSize); works. Acquire or generate samples until you stop the task

    But it is not possible to derive the internal counter of the clock (for example ' Dev1/ctr0"):
    DAQmxCfgSampClkTiming (taskHandle, "Dev1/ctr0", maximumExpectedSamplingRate, DAQmx_Val_Rising,
    DAQmx_Val_ContSamps, bufferSize); does not work. Error: Acquire or generate samples until you stop the task: make sure that the name of the terminal is valid for the specified device. See Measurement & Automation explore valid names of terminals. Property: Property of DAQmx_SampClk_Src: DAQmx_SampClk_ActiveEdgeSource device: Terminal Source Dev1: Dev1/ctr0

    Hi datafriend,

    using what it says is correct:

    Or sample DI source clock: Any PFI, RTSI, HAVE sample or convert clock, AO, Ctr n out internal and many other signals sample clock
    The digital subsystem doesn't have its own dedicated internal synchronization engine. Therefore, a sample clock must be provided another subsystem on the device or from an external source.

    This means that if you do not use an external signal as clock you can use the sample clock to HAVE it on board or at the output of the internal counter.

    There are also 2 ANSI C examples in this regard:

    http://zone.NI.com/DevZone/CDA/EPD/p/ID/4485

    http://zone.NI.com/DevZone/CDA/EPD/p/ID/4488

    So in both cases you have to use a fictitious task you need only for the generation of the internal clock (HAVE or CTR)

  • How do switch you between multiple channels to indicate which channel to acquire the data from?

    I'm trying to builld a VI where I can have an option to enable or DISABLE multiple channels depending on the modules plugged into the chassis and then acquires the data of the channels which are turned on and where other acquisition parameters do not change. Is there any specific/switch where can I do this? Please answer as soon as possible. Its quite urgent. Thank you

    You use DAQmx?  To change the assignment of the data acquisition channels, you must close the currently open session and then create a new session with the new channel definition.  So the order of execution:

    Create task or virtual channel - read - clear task of triggering and synchronization of the configuration - set new channel list and to create a task - read - clear task, etc...

    Question about the use of Apple TV2. I live in a city where Comcast caps using 300 GB/month data, more of exhaust us sequences of movies and tv via a new Apple TV2 (64 GB) and our application of Samsung Smart TV. I just bought my first movie via iTunes and have a question about how / where it is stored / games.

Can it store movies AppleTV2 I bought, or what I need to download them to my computer? I read that HD movies don't play well through HomeShare or iPlay, but perhaps beyond the news.

    Use the same amount of data streaming and download.

    The only difference would be if you want to watch the movie several times. In this case, download the movie first, would be more effective in terms of use of the data.

    HIGH_VALUE datatype is LONG. You may not use for a long TIME in WHERE clause expressions. You need to loop through the partitions by selecting HIGH_VALUE and then comparing. Secondly, there is no need to select double to calculate expressions. For example:

    Select to_char (add_months (trunc (sysdate, 'MM'),-1), 'YYYYMM') | ' 00' in the double last_mnth_var;

    should be replaced by

    last_mnth_var: = to_char (add_months (trunc (sysdate, 'MM'),-1), 'YYYYMM') | ' 00'.

    and there is no need to add_months here:

    last_mnth_var: = to_char (trunc (sysdate, 'MM') - 1, "YYYYMM"). ' 00'.

    But the main question is simply ALTER TABLE MODIFY PARTITION COMPRESS allows compression but does not compress. You must issue ALTER TABLE MOVE PARTITION COMPRESS:
