Eccentric MAX program?

Sorry if wrong forum. I tried digital I/o, but no answer & I can't find a forum for MAX.

I have a problem with a client computer which houses PCI-6071e & PCI-6043. In MAX test panels.

I have lines of encoder quadrature clinging to PFI0 & PFI1. If I go to the counters, for number of edge, trigger = PFI0 (or PFI1) I count when I turn the encoder. But if I go into digital I/o I get no response from the encoder. All 8 lights remain lit.

Tried it on another machine (with USB-6211) it works fine.

MAX or drivers are right divide? Not possible to have good counters and signals through the PFI is bad, right?

Walter donovan,

I think you misquoted your second DAQ device model number - I do not think that we do a 6043.

If you want to use a map of series E (6071E) with a quadrature encoder, you will have to plug a little differently. Most of quadrature encoders have at least two signals of the pulse output (and possibly a third, which is the output of the index). These two impulses, A and B, must be connected on the DAQ counter input source (PFI3 for PFI8 for Ctr Ctr 1 or 0) and the P0.6 of entry respectively. So I recommend that you configure a fast edge counting task to the MAX to verify that this configuration works ("outwardly controlled" use for management).

The reason for which he worked a litte differently with your other card (USB-6211, M series) may be that the two card counters are different. M series supports the features of NOR-TIO meter, such as the separation of the two edges and quadrature encoding, and E series does not (for other differences, see this article). However, you can still use your card in the E series with a quadrature encoder as I've described. For more information,.

The use of quadrature encoders with DAQ of E cards series

I don't think that anything that is wrong with MAX or your drivers. The lights may or may not reflect the signal on your digital inputs according to the speed of the train of pulses from your encoder.

  • Automation explore virtual SMU-1082

    I have just ordered a PXI system of NOR and want to start programming while I wait for delivery. I thought that I could create virtual devices SMU to do this, but I could be wrong in my understanding of the MAX program.  While I have used LabVIEW for almost a decade, I never needed to use "measurement and Automation Explorer."

    When I chose "create new" under "devices and interface" "Simules NOR-DAQmx..." ", I couldn't find the SMU-1082 chassis or the module(PXIe-8840) of base I will use.  Am I going about this all wrong?

    Thank you for your help,

    Ron

    Hi Ron,

    Unfortuantely, you will not be able to simulate a chassis SMU or controller in MAX. The SMU chassis will automatically identify in MAX when you plug on your computer, while some of our former PXI chassis will have to manually identify. If you want to simulate a chassis, you can simulate a PXI chassis and put your modules SMU simulated in it.

    The good news is that you don't need to simulate a chassis in order to simulate a card. To simulate the 4304 to the MAX:

    1. Click devices and Interfaces

    2. Select create new...

    3. Select the simulated device NOR-DAQmx or modular Instrument

    4. You can search for 4304 and select the module.

    I will note, the SMU-4304 is first supported in our driver NOR-DAQmx 15.1.1. If you have an older version of DAQmx installed, the device does not appear as an option in MAX.

  • Zero DAQ reset

    Can someone tell me how to reset a diagram LabVIEW data acquisition card without using MAX Program?

    After the failure of a test, LabVIEW will leave the reverse PIN. Then, when I run the test again, it will continue to fail unless I have manually click on reset device button display in the image below.

    Please can someone me ASAP?

    Additional information:

    -J' use card NI PCI-6251.

    -J' use DAQmx

    -I'm using LabVIEW 8.0, but have access to LabVIEW 8.2

    -J' also uses a quadrature encoder

    Hello

    There is a Device.vi to reset DAQmx.  This will give you the same functionality the device reset to the MAX:

    If you don't want to reset the whole device, you can also set individual of High/Low or Tristate programmatically lines if you wish.

  • Delays in DAQmxWriteRaw when you use several cards PXI-6733

    Application:
    I have an application that generates and writes the analog data at 300 kHz slightly underneath.  Data generation and output take place every 14 ms (we'll call it who a 'block',) through an event EveryNSamples leave a timing sheet.  In each block, 4000 samples of analog data are generated and output to 6 of the 8 channels of analog output of the PXI-6733.  The output buffer is set to twice the block 4000 writing samples and pre-filled with 4000 zeros, so the output is always a block behind the data generated.  If a single block exceeds 14ms to generate and write on the analog samples, the output buffer will be against the wall and exit stop (regeneration is disabled.)  I recently needed to add more than 10 output channels, so I installed a second PXI-6733 map in the chassis and set up a second analog output task to write the second map.

    Problem:
    As analog data are generated on demand in each block of 14 ms, the program cannot take more than 14ms to generate the data and write them on the cards, otherwise we will underflow analog output.  Thus, any unwanted delay must be avoided.  Data generation stage does not take very long (in my test it is off and decision< 1ms,)="" but="" i'm="" seeing="" some="" problems="" when="" i="" write="" the="" data="" to="" the="" pxi="" cards. ="" i'm="" using="" the="" daqmxwriteraw="" function="" to="" write="" the="" samples="" to="" the="" cards. ="" the="" function="" is="" being="" called="" twice="" every="" update="" loop:="" once="" for="" each="" output="" task="" (card). ="" when="" i="" added="" the="" second="" card,="" i="" noticed="" that="" occasionally="" the="" call="" to="" daqmxwriteraw="" would="" take="" much="" longer="" than="" 14ms,="" causing="" buffer="" underrun="" errors="" (-200016)="" on="" the="" second="" card,="" or="" regeneration="" errors="" (-200290)="" on="" the="" first="" card. ="" i="" inserted="" timing="" markers="" around="" each="" call="" to="" daqmxwriteraw,="" and="" i="" see="" that="" normally="" the="" calls="" each="" take="" around="" 4.8e-5="" seconds="" to="" complete="" on="" card="" 1="" (whether="" alone="" or="" in="" conjunction="" with="" card="" 2). ="" on="" card="" 2,="" the="" calls="" take="" usually="" take="" about="" 4.8e-5="" seconds="" to="" complete,="" but="" they="" occasionally="" spike="" to="" between="" 5="" and="" 40ms="" (e.g.="" 6="" out="" of="" 300="">

    I wonder what would cause these erratic spikes in time it takes to DAQmxWriteRaw BIE called on the second card.  Is there a known issue with the help of 2 PXI - 6733 s in the same PXI chassis?  Could there be some sort of conflict of resources (not enough channels DMA, etc?)  The two report cards they have in DMA mode, and fill FIFO priority is set to NotEmpty.  The problem also occurs when the transfer mechanism is set to interruptions.

    Other Observations:
    I noticed the first edge of calendar corresponds to the point in the program to the location of loading the dll "nicesru.dll."  I can't find any information that features in this dll, and I don't know if it's a symptom or a cause.

    I also noticed that when an error occurs, I can't seem to stop and clear the tasks of production.  After trying to stop it and cancel all active jobs, keeps blinking the link on the PXI chassis light.  To reset, the only way is to go into solution of measurement and Automation Explorer and reset the second card 6733 manually (or use ResetDevice C calling).  There seems to be only the second PXI-6733, and it also happens when using the test panels in the MAX program.

    I was able to solve the problem by moving the PCIe card in the PC to another location.  I assumed the problem was with how bus PCIe are managed by the motherboard, or how the resources have been allocated to the cards in this particular niche.  Move the map on the slot 16 second x on the motherboard seems to have solved my schedule delays.

  • What should I do when I can communicate with my instrument NI MAX through other programs, but not of LabVIEW?

    Hi all, this is a question that I had a few times before in one form or another.

    I use a Boxcar Integrator (245 SRS is the interface) for my experience. I connect to it via GPIB using my Agilent GPIB/USB interface. My program runs in LabVIEW, and I used it successfully in the (very recent) past.

    However, sometimes if I get LabVIEW or something, some weird stuff starts past trying to connect to it. For example, after the LV exit and go back to the top and any attempt to run my program, it throws the error:

    Error 1073807339 has occurred in the CITATION read in OR_Boxcar_ReadAnalogPort3.vi-> OR_Boxcar_SimpleTest.vi

    Possible reasons:

    VISA: (Hex 0xBFFF0015) timeout expired before the operation is complete.

    Which essentially means that he cannot connect for some reason or another (don't worry, I'm on the right GPIB address).

    So I go to equivalent NI MAX or Agilent (Keysight connection Expert), proceed to part communication from VISA to either and manually, connect with the machine. And it works! If clear my computer is communicating with the machine at this point, but not of LabVIEW.

    This could be the cause, and what I might try? Thank you!

    Oh shit, I forgot about it! I solved the problem, it was actually a 'me' problem is not a problem of LV. Even my solution would not be to help someone else who finds it. I was trying to read from my instrument, but it is in synchronous mode, so it generates an error if you try to read her when a data point has not been loaded in its buffer. I did something unusual, so it was not a point of data loaded into its buffer.

  • Setting by exporting the default value for Max in Quality program

    Hi Zac,

    I'm trying to find a way to define a default value for the 'Maximum use rendered quality' box located on the dialog window export settings. Is it possible to programmatically set a value for this box (maybe in the call to exSDKGenerateDefaultParams)? Or would a value 'default' for this box be treated by creating a "Preset"?

    Thank you
    Josh

    It is the exporter to use the setting provided by the host in exDoExportRec.maximumRenderQuality.  The exporter must define SequenceRender_ParamsRec.inRenderQuality and inDeinterlaceQuality to kPrRenderQuality_Max, if the value.

  • Problems with the new Macbook pro 15' maxed out

    Here's a quick post about my experience so far with the new macbook pro. I just got a brand new fully maxed out in spec macbook pro 15 inch 1 to SSD 16 GB RAM AMD R9 370 m GPU (set to automatic switching is not always) and a 2.8 to 4 GHz i7. I turned on and set it up which was nice and took 2 minutes. Then experience decreased a little when I saw an EST 05:36 hours of battery life remaining to 94%. So I loaded 100% and it is still 60% of battery life announced and no program running that I literally just signed a brand new machine.

    Then I tried to use the migration wizard to import a backup of my iMac 5 k so I can do everything on this clone for my laptop. After having successfully connected (he told me if my password for time machine was incorrect or not) it froze and did nothing, continue did nothing.

    Then place had to call support, was a guy on the phone in 30 seconds and I unplug and restart the machine time, always that same question so I transferred to a guy with "more training". The new guy I could say knew a little more and knew that I knew how to set my password or if I walked in their properly for a bit but they all have been set for the same password just for this. I created a second admin account called "test" under his leadership, and when the migration assist froze on this account, he was surprised and proceeded to transfer me off.

    I preceded to restore fully the machine into thinking that my account setup is causing trouble with the migration assistant, and it turns out that the closure of that laptop it can only continue to 'download additional components', while that connected for 30 minutes so all last night was wasted, and now I guess he's got 5 left 12 hours to download original 'things '. Keep in mind that I can download 5 GB in one hour... After he wake up this morning and ending up where I left it last night :/ he says 84 hours go, now 72 and 51 and it is not updated even once in seconds, it took 20 minutes to 84 minutes to 51, it's literally a day 2 reset extravagance or what? Just to download it I can only imagine the actual plant until I can install my programs.

    The cost of the laptop was about $3600 but paid ~ $2900 after headphones were included and $250 off for delivery to students and other issues on the agenda of the process itself that is not my complaint, what happens, but sitting with a new camera and support useless just to ask me if I can use actually tomorrow at this price are unacceptable.

    I would like to continue using it for a while.

    Hi Proday,

    What you hear with * Tj * for CPU?

    The laptop is equipped with a processor Intel Core i5 430M CPU. The maximum clock speed is 2.26 GHz and 2.53 GHz maximum turbo frequency. If you run programs with high utilization of the processor CPU will automatically be overclocked to 2.53 GHz that will give you a performance boost. This technology is called Intel Turbo Boost Technology.

  • Problem of the intranet: "Firefox doesn't know how to open this address, because the Protocol (k) is not associated with any program."

    Creation of an intranet to a collection of security videos and am linking to a video through a picture icon in the form of:

  • necessary to enhance Network.http.Max - connections-per-server to javascript

    I have an AJAX web application which is very sensitive the number of connections allowed by the browser. Bad things happen when the limit is set at the bottom: frozen screens, the uncommitted transactions, deadlocks, etc..

    To avoid this, I need to check the current value of the configuration parameter "Network.http.Max - connections-per-server" program (i.e. javascript code) and to reject a request if the limit is too low with the instructions appropriate for the user.

    I guess that's possible because "subject: config" restores all values of settings and even allows for user to change. However, the code-behind for the page is very complicated, so I can not understand how to accomplish my task. All I need is a function or a method returns the current value of a given configuration parameter.

  • Satellite P775 stuck program on the use of the disc a vast

    Hello

    I have a strange problem on my laptop Toshiba Satellite P775 program with Windows 7.

    The laptop boot from time to time, slow and heavy i/o operations (I can see it via the indicator disc to surveillance). Windows not crushed, but the heavy IO makes the laptop unusable.

    Recently I reinstalled Windows (return to factory settings), but the issue has not disappeared.

    A few words about 'stuck ':

    1. once the laptop has been cooled for a long time - more than 1 hour - never occurs during initial start-up.
    2. when a problem starts, it does not disappear after stopping and restarting the laptop
    3 is coming during the connection process (stuck when connecting)
    4. never happened to me when you work in "safe" mode
    5. Windows not crushed, the mouse is generally sensitive - just very heavy and slow disk access makes virtually every application unusable.

    * The most recent research (quite shocking to me): once it goes all in running, I tried to unplug the power cord, then plug it in then after a few seconds. To my surprise, the "disruption" caused by the power connectivity - caused the laptop back to normal.*

    No clue on how to debug and fix the problem?

    Thanks for the care,

    Hello

    In my opinion, there are different reasons for this.
    First reason could be a large amount of processes that are running in the background
    Theoretically, it could be possible that a process stresses the CPU and thus the performance of the laptop is slowing.
    A HARD disk problem can cause this kind of problems too.
    As you can see really hard to tell what could cause this problem.

    From my point of view, you should start by running processes.
    Use check the CPU in the Manager of tasks (tab CPU) while this problem occurs.
