Get samples of the clock machine (NEITHER with NOR cDAQ-9172-9422)

Hey guys

I'm trying to produce data for the position of a 1000 Hz all about stamping press with an absolute encoder which is connected to the NOR-DAQ.

Two not that I am trying to program, but can not understand:

(1) use a hardware clock to trigger the acquisition of the data at the selected speed

(2) synchronize the three data acquisition modules I have to ensure that all data are received at the same time

the material I have does not seem to have any counters. A few examples that I read would not go because of this.

Any thoughts? If there is some examples/tutorials about this problem that I have missed please let me know.

Thank you

Hey, Rohan,.

Thanks a lot for your help. I was talking to a National Instruments process engineer yesterday and it me that the problem was the vi calendar clock source option - instead of using AI/SampleClock, I had to use the time base of 100 kHz clock that did not appear in the list until I checked the option "ListAdvanced Terminal" in the name of e/s filtering dialog box. You must right-click the constant/control of the source of the clock and select I/O name filtering to open this dialog box.

Thanks for all your suggestions, I'll try to apply it and check the performance.

  • Impossible to get more than 1 channel to read with DAQmx cDAQ-9172 under Windows 7

    I have the cell load, voltage, and input thermocouple connected to a cDAQ-9172. My sensors entries have been scaled and verified in MAX, and all of them work.  DASYLab 13, the driver is "dcDASY.dll" and the hardware configuration is "NI MAX.

    When I add a task NEITHER-DAQmx Analog Input (that is, a set of scales) it appears correctly. If I add a second channel of the task and select it, I get this message:
    'Channel of task name saved with the module is not available. DASYLab resets the module parameters for usable first channel name task. »
    The name of the task remains the same for each new channel I have Add. If I change the name of the task by using the tab to the drop down menu, it says:
    "You have configured several ways out for the module. If you modify the task, you lose the settings. You want to change the task? »
    Both display the same data channels, and I can't work simultaneously several channels. It seems I missed something obvious, but I can't.

    The parameters are:

    Measurement and Automation Explorer 4.6.1
    NOR-DAQmx 9.0

    Material:-cDAQ-9172
    Slot 1 - NOR 9215 (0-10 Vdc analog voltage)
    Slot 2 - NEITHER 9211 (thermocouple)
    slot 3 - NI 9481 (relay)
    slot 4 - NI 9237 (entry deck w / excitement)
    housing 5 - OR 9402 (DIO)
    slot 6 - NI 9263 (0-10 Vdc output analog)

    Thank you

    You can't perform different tasks (continuous) HERE on a single chassis. The first tasks that starts will be 'the resource booking '.

    Combine the AIs of the various modules in a single task (see photo): start by creating the task of thermocouple. Then add AIs 9237 (e.g. Kraft) and 9215 (volts) using the button with the blue, symbol. Set the mode of synchronization of the task of "continue". Save the task, start DASYLab (second photo).

    Change a task (adding channels, etc.) to the MAX while DASYLab works always, will result in unexpected behavior. To synchronize the configuration of MAX with DASYLab, you will need to close/restart DASYLab or use the 'sync' of the function (see photo 3 "syncmax.jpg"). You can set this function as a shortcut by right-clicking on one of the eight green or grey circle things.

    You should think about an update of the MAX/DAqmx drivers. 9.x is a little outdated.

    Updated at least DAQmx 9.9, better 14.x or 15. 0 (stay far 15 1.x).

  • Impossible to get 'notes' of the virtual machine

    I tried to use a powershell script to get information from the virtual machine. I can get VMHost, VMname and GuestVersion using the script in the following, but failed to get the notes of the virtual machine. Anyone know why I can't get notes, please help me with that. Thank you in advance.

    report = @)
    foreach ($vmView in (Get-View - ViewType VirtualMachine))
    {
    $report += $vmView. Select-Object @{Name = "$vmhost"; Expression = {($vmView.Runtime.Host Get-View).} Name}},
    @{Name = "VMName"; Expression = {$_.} Name}},
    @{Name = 'Notes'; Expression = {$_.} Description}},

    @{Name = "GuestVersion"; {Expression = {$vmView.Guest.GuestFullName}}
    }
    $report | Sort-Object VMName-descending | Export-Csv "d:\vm_GuestVersion.csv" - NoTypeInformation

    There is no need to do it with the cmdlet Get-View.

    You can do

    $report = @()foreach ($vm in Get-VM){    $report += $vm | `        Select-Object @{Name="VMHost"; Expression={($_.Host).Name}},            @{Name="VMName"; Expression={$_.Name}},            @{Name="Notes"; Expression={$_.Description}},            @{Name="GuestVersion"; Expression={$_.Guest.OSFullName}}}$report | Sort-Object VMName -Descending | Export-Csv "d:\vm_GuestVersion.csv" -NoTypeInformation
    

    If you want to do with the cmdlet Get-View for any reason, you can do

    $report = @()
    foreach ($vmView in (Get-View -ViewType VirtualMachine))
    {
        $report += $vmView | `        Select-Object @{Name="VMHost"; Expression={(Get-View $vmView.Runtime.Host).Name}},
                @{Name="VMName"; Expression={$_.Name}},
                @{Name="Notes"; Expression={$_.Config.Annotation}},
                @{Name="GuestVersion"; Expression={$vmView.Guest.GuestFullName}}
    }
    $report | Sort-Object VMName -Descending | Export-Csv "d:\vm_GuestVersion.csv" -NoTypeInformation
    

    But note that as you need a view of the GET each time for the host name, performance will suffer.

  • vmreconfig.pl add a CD/DVD device will fail if the virtual machine created with vmcreate.pl

    I am trying to add a cdrom to my VM I created with the vmcreate.pl.

    When I use the script vmreconfig.pl to create the cdrom I get the following error...

    Cannot use a value that is not defined as a reference to a matrix to/usr/lib/vmware-vcli/apps/vm /... AppUtil/VMUtil.pm line 898.

    OK so I have create a cdrom in vSphere and try again manually...

    Addition of the cd 'cd '...
    Virtual machine 'vmname4' is reconfigured successfully.

    OK, so I think that my VM I created with the vmcreate.pl missing the ide0: 0 or something...

    Any suggestions on how I can do this?

    I'm doing the following...

    1. create the virtual machine by using vmcreate.pl.

    2. Add the CDrom to the virtual machine using vmreconfig.pl.

    Thanks in advance.

    Just watched this.

    The vmreconfig.pl script does not handle the case of a device not defined in the VirtualIDEController object array.

    Look like the real device table is not defined until an IDE device is actually connected (or when a new IDE device is added).  I'm not 100% sure of what generates the actual peripheral table off the coast of the VirtualIDEController, but the case of a table of undefined device should be handled in the script to reconfigure.

    I can see the two solutions here, first write a custom script that adds the CDROM and manages this one-off case.  Then, modify the vmreconfig.pl script to handle this particular case of a painting of the disconnected device.

    In VMUtil.pm, you will find line number 929:

    My = $unitNumber $# {$controller-> device} + 1;

    This is to change:

    My = $unitNumber (set $controller-> device)? $# {$controller-> device} + 1:0;

    There may be other cases in the VMUtil.pm module that needs to be updated as well.  For this reason, it may be better to just write your own custom tool.  However, the simple correction above may let you go ahead with your project in the short term.

  • Import the virtual machine created with .exe files

    Hello

    I'm new in the world of the virtual machines, and I'm sorry if I'm going to say something stupid.

    I take a .net class and the teacher has a virtual machine (windows XP with software) ready to pose with 4 .exe files.

    I installed VMfusion but now I have no idea how / if I can import the teacher VM fusion.

    Is this possible? If this is not the case, what can I do else?

    Thank you very much

    Luca

    Find a Windows PC and run the exe files to extract the virtual machine, precompiled.  Just copy the folder of the entire virtual machine on your Mac, and then open/run the virtual machine using the merger.  VMware virtual machines are portable between products and host operating system - there should be no reason to "convert" or "import".

  • Where can I get information about the compatibility of communication with Windows network file?

    Can anyone give me a suggestion of best practices on how to travel with my laptop and work on files stored on my home office? Or at least offer some references that will tell me what is possible?

    I just got a convertible tablet from Lenovo Ideabook three books with Windows Home Premium. Trying to figure out a system to keep files synchronized between it and my Vista Pro Office turns out to be a colossal tar baby.

    Unlike most other posts here, I do not turn into bugs. Everything I try seems to work not by design.

    Some examples of things that I am wasting time because I don't know what is possible:

    In a perfect world. I have set up my tablet to keep copies off some my Vista Pro data connection-file/folder.  But HP 7 only acts as a server for offline files, not a remote client Pro Vista offline files.

    7 HP can remote desktop to Vista Pro, but can't Vista Pro remote desktop to 7CV?  Office using my home to manually sort the files remotely is the closet thing I have a solution, but the risk of catastrophic reckless mistakes is optimal when you replace the files that have the same name of a compressed small screen.

    An even worse solution would be to open my file Vista Pro sharing and printers to the Internet, because that would invite hackers to toy with break my Windows passwords. Even so, I predict when I would be out of reach of the Internet and the files that I need to back the shuttle.

    I believe that I can not establish a VPN connection between two computers going in both directions, although they all have two so-called VPN capability.

    "HomeGroup" of HP 7 has no potential compatibility with traditional windows "working groups".  And 'Libraries' of HP 7 do not work in offline mode, which makes wonder if Microsoft invented new systems which differ only the 'old' enough to make them incompatible and unnecessary.

    Here are some examples of ideas that have not panned on. I could save a lot of time if I could find everything what is possible. I searched the documentation from Microsoft and only found misleading statements that Windows 7 is going to do this or that, only to discover that what Windows 7 is supposed to does not apply to the version of HP I.

    I will be eternally grateful if someone has a scheme personally knows it will work.

    Thank you.

    Hi jaygourley,

    I suggest that you create a working group and then check if the problem persists.

    1. open system by clicking theStart button, click Control Panel, clicking system and Maintenance, and then click System.

    2. undername computer, domain, and workgroup settings, click change settings. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

    3. click on the tabcomputer name and then click change.

    4. underMember of, click on the Working Groupand then do one of the following:

    ·        To join an existing workgroup, type the name of the workgroup you want to join, and then clickOK.

    ·        To create a new workgroup, type the name of the workgroup that you want to create, and then clickOK.

    If you change the name of an existing workgroup, a new working group will be created with that name.
