Card required for control special measures

Hello!

We have some NOR-DAQ cards (PCI-6221, 6251 and 6036E) but none of them seem to be capable of the following measure.

There is a digital pulse train that must be received (practically with a meter). To measure the VOLTAGE to a channel of AI when a pulse is received. The frequency of the pulses can be 1 KHz, therefore generating events at each pulse for the PC is not viable. He must also know where the pulse OCCURRED (something as the card should have its own clock and should be able to put next to the measured voltage value).

In addition, the map should give a sign of output (pulse change or line) of 1. the number of pulses reached a given amount or 2. the voltage is lower or exceeds a value given to a channel to HAVE. If an automatic output is not available at least we have an event to the PC.

Will there be any card to fix this? In fact the card must have at least two meters since we have two trains of digital pulses, but only is active to a degree. Thank you very much for your suggestions!

Could you clarify it please ", we have two trains of digital pulses, but alone is.
Active to a degree.  You check in for a number of pulses on several lines?  You have more than one channel of Analog Input?

Without taking into account the requirement for the 2nd train of digital pulses for the moment, to my understanding of the application the 6251 could do you need:

1. the signal of AI must be connected to the 6251, since it is the only one of the three that supports analog trigger.

You need to configure an analog reference trigger to allow comparison shipped.  You can use the line to HAVE it if you are sampling just one channel (or an APFI line if you're sampling from multiple channels).  Export event of analog comparison will tell you when the signal is outside a certain threshold (the graph presents 'Entering the window' but you can select "Exit" instead):

2. connect the Digital pulse train to one of the PFI lines on the 6251.  It will be the sample for your task clock to HAVE.

4. use the same PFI line as a source for a meter (pulse) output task.  Set the initial delay so that when the desired number of pulses have been counted you will produce a pulse on the output of the counter.

5. you now have a line telling you what N pulses have been reached (from step 4) and a line telling you where I is outside a window (in step 1).

6. If you want to timestamp pulses using the edge of the Office counter, you must use the counter 2nd as a county of edge stamped with the external pulse as your sample clock signal.  This will give you a very precise timestamp of your external impulses (compared to the beginning of the task).

If you need for impulses of timestamp on multiple lines, you can look in the task configuration of change detection of DI on the 6251 and using change detection event as the sample for the task of counter clock.  You must implement logic in SW to determine which line has generated the actual event.

You have also 4 other counters to play with on your other DAQ hardware two, so depending on what you want to do, you should have a little flexibility.

Best regards

  • Recommended structure for separation of measurement and control

    Hi everyone, I m going to write a labview program for a test bench that requires to control external devices via the outputs of the NOR-DAQ modules in a chassis usb DAQ and also various measures of tasks via DAQ modules in the same chassis. The output should work for a long time, lets say for about a hour and shouldn´t be interrupted by (i.e. errors in labview code). Measures will be done sometimes but require the variation of some parameters of output. For this type of installation, rather would you recommend to separate the control - and parts of the measure in two screws and allow them to communicate through global variables or rather put in a VI with refined error handling to avoid failure of the output? Or, of course, are there other, better tailored approaches for this friendly task? Thank you for your ideas!

    You should consider master - slave with 1 master architecture and 2 slaves.  A slave can perform control and other measures.

    Intercommunication between the loops: you can use globals or queues. Queues are recommended that globals (freedom of race )

    See rear queries if any.

  • JetDirect MIO card JetDirect J2556: memory required for?

    I want a JetDirect MIO card for an old LaserJet 4 Plus. I was watching a JetDirect J2556. However, I have read that the printer needs 16 MB of memory for the card to operate. Is this true? I read on one website. The site sells memory and maps MIO. I tried to find a PDF or a manual or something HP which specifies the requirements for the card but I had no luck it is.

    Devices have usually minimum 16 MB of memory when the functions of duplex and network available and no less than 8 MB for devices with function.

    I think that alghough the Jetdirect card may have installed/configured for use with less than 16 MB of memory, but you may experience performance problems if memory is low.

  • Micro SD card drive is required for the format, but format used?

    Im trying to get music and stuff on my phone and the disc, I put my memory card must be formatted, but when I try to format it, it always says "Windows cannot format. Help?

    Hello

    If disk management is unable to format your Micro SD try to do it in the command window. To do

    • Click on the start ORB in windows and type in the cmd search box
    • It will open a black window. There, type diskpart
    • Then type list disk
    • After that, you see a list of drive connected to your machine. Select your micro SD card. For example is your hard disk is on no. 1 and the microSD card in no 2 then typeselect disk 2
    • After that, you will see written disc 2 is now selected
    • Then type clean
    • create the primary partition
    • format fs = fat 32 fast
    • output

    See if your microSD has been formatted.

    If none then try to remove the card SD of your mobile phone (if you do) and try to connect a micro SD adapter and try to format it from there. Maybe it's your phone that prevents the operation.

    Otherwise if you already use an adapter for micro SD do, then check if it is not locked (with the key was found on the side of the adapter) or try to try with a new adapter.

    Hope this can solve your problem,

  • UMI-7774 required for readers of nor?

    I'm a movement control system design using 3 stepper motors (or Nema 23) and therefore 3 or P70360 readers. Is a umi-7774 required to connect to the controller 4 card pci motion-axis?  (I'm confused as its description on the site nor said that it is necessary for the 3rd party readers BUT in discussions I've read a lot of people have used umi 7774 or readers)

    Hello aks.

    Yes, you will need to purchase and use our 7774 universal movement (UMI) Interface to connect the three engines of readers / motion controller card.

    He could have confused because it does not explicitly say that it is necessary for the 3rd party readers, but not necessarily required for our readers. That said, the vast majority of customers use the UMI Board, because it eliminates the need for custom cables and makes it much easier to connect to several axes.
