Sync CAN read, CAN write and DAQmx

Hi all

I have setup an application with a cDAQ 9178.  I have several digital and analog i/o cards and a BOBBIN card in the chassis.

The unit is used in a hydraulic test bench.  I'm reading and writing of my analog equipment and digital I/O timed and synchronized.

I also managed to synchronize my CAN read waveforms with my entry analog daqmx and so sync CAN read with DAQMX.  I used one of the examples in the finder of the example to handle this.  Now I want to synchronize my CAN write waveforms with my CAN read waveforms and so also with analog and digital DAQmx tasks.

Are there examples where using the API OR-XNET which shows how synchronize CAN read waveform and CAN write waveform on the same interface?

I tried to read my signals output by adding them to the list of signals of the CAN read signals, but they did not show.

Thanks & best regards,

Lieven

Hi Simon,.

I have the module 9862 in my chassis and have managed to use the trigger for the start of my NI9205 analog input card to synchronize my readings CAN with all my other analog I/o.

Now, I just wanted to see my CAN output signals synchronized with the rest of the signals.  At first, I tried to use the same trigger for my BOX of output on the map, but somehow, it did not work properly.  After looking a little on the forum and in the examples that I found a knot of XNET SESSION property called EchoTX and used on my BOX of exit session.  I then added my output signals to my list of input signals and was able to read my output signals.

That's what I was looking for.

Thank you

Lieven

    The DIO module channels started writing? You need to go into the properties of the module and select this option. Find the module in the project, right click and choose Properties. I don't know which module you have, but if it's 8 channels, you can usually do it in groups so that you can put channels 0-3 to read or write and channels 4-7 to read or write. But you will not be able to each channel individually have it's own settings, cordially. But it may be different on certain modules.

    I suggest you look at the settings.

  • Help? the source volume is read-write and can not be disassembled...

    I use 10.11.5 on an iMac 21.5 ", end of 2009 and I want to restore the OS X 10.11.5 to HD on an external drive but I get this message" Source volume is read = write and cannot be disassembled, so it cannot be copied from block.

    You use disk utility's restore feature?

    If the HD has a recovery partition, you can make starting in place of the recovery.

    Or you can use SuperDuper! (the basic version is free and can copy the entire disk, the paid version allows "smart updates", which copies only files that are different, saving time) running on externally to perform the copy.

  • Whenever I insert a USB in my PC is not autoplay, I do not have available to all group policy, and I can't read or write CD/DVD

    Original title: "Autoplay, group policy and CD/DVD"

    Hello

    I have two questions actually worry,

    First of all, I have Windows Vista Home Premium Service Pack 1 installed on my PC

    My first problem is that whenver I insert a USB in my PC it doesn't autoplay and the option is not available at all even when I get clich the drive itself, I went Microsoft support and installed security update 950582 and still no hope. I also can't find the NoDriveAutoRun or NoDriveTypeAutoRun in the registry because I don't have the key explore in both policies.

    In addition, I have not available to all group policy.

    My second question is that I can't read or write CD/DVD even if I have the driver installed, I tried the DVD Microsoft repair but it shows that the repair failed.

    Thanks in advance and hope to receive a solution soon.

    SAS ING.

    Hi Sas Eng,

    There are a few solutions to the question of automatic playback on the following link:

    http://Windows.Microsoft.com/en-us/Windows-Vista/Troubleshoot-AutoPlay-problems

    And if the solutions provided for the DVD ROM Lorien did not help, as you say, it is probably a hardware fault.

    Try the steps are on the link and let me know if it helps!

  • CD/DVD CAN'T READ OR WRITE?

    Hello, me too I have the same problem. Mine is Matsusita DVD RAM on Toshibs L310. It is read or write. Someone can help me. Mr.Fix, he finds that he is ok, however said more attention needed support thro. Help, please.

    Have you asked Toshiba? It is their material, they need to know. Cables come loose from time to time, this might be a cause, who knows? Alternatively, they could simply tell you to start by uninstalling the CD/DVD player/burner?...from the list, in Control Panel/Device Manager? The unit itself, just let the driver here.

    To see if the operating system 'found' it and reinstall?

    Consider the "age" of this unit, it becomes less reliable he will get. If this is the case, simply replace it with a new one.

    Toshiba could tell you the same thing, keep that in mind.
