• Programming of the event with digital I/o

  A Structure of the event can be used with digital I/o?  All the examples I've seen show the Structure of the event used with the keyboard or the mouse.  But have not found many examples showing the Structure of event used with digital input.  I'm mainly looking for a link to an example. But you can provide any help will be appreciated.

  Howard.

  Yes, you can register events DAQmx.  Look in the IO position-> data DAQmx-> Advanced-> palette of events acquisition DAQmx to start, or search for events DAQmx.  All DAQmx devices support events of change detection, which is probably what you want if you have the digital I/o, in order to verify that it is supported by your device.

• USB6259 static with digital trigger

  Hello

  I have a VI that controls a control of linear motor with digital lines. At one point in the program setting one of these pipes triggers a task of analog input and a task of Pulse counter. This is done by putting a wire between the digital line and for example. PFI0 use this as a the input trigger. This works well.

  My general question: is it a solution, where I can use an internal signal of the 6259 avoiding the connection of the wire?

  Matthias

  Hi mq17,

  I have found no clear information, saying that it is possible (or impossible). What you should try is to create an internal route between the digital line and PFI0 using the DAQmx connect Terminal VI. I can't guarantee this will work, but it's worth trying:

  DAQmx connect terminals (VI)

• How to fill a control ring with chains [] array?

  How to fill a control ring with chains [] array?

  It must be karma. (Try really bad karma because I couldn't post this question in my original)

  I must have been a Really bad guy in a previous life...  It's not like I'm bad in this one...

  So... what I want to do this time around?  Something that I thought would be easy... Well... it's a long story...  I had a simple solution, but the client wants something else.  -sigh-

  Here is what they want...  They want a control that allows for multiple selections to a control of the ring (or a control that allows a drop down selection menu).  Bites are filled at run time because it is based on 10 000 other precedents of things this particular choice.  So it must be dynamic.

  The snippet of code & images below show what I'm doing a little...

  The bottom image shows on the right bites which is filled in the control of the ring.  Since the number of items / items changes, I didn't have a bunch of controls stacked on another.  In addition, I have to deal with an unknown quantity of selections.

  Does anyone have a solution that can be recommended?  If so, can you share the solution / idea?

  Thank you

  I have posted a code that does something similar here: http://forums.ni.com/t5/LabVIEW/array-of-cluster/m-p/1822451#M625032

  It uses a table hint and individual controls that are moved on top of the table and populated as needed.  This approach might work for you?  You would need a two-column table and only control ring, which you would fill properly whenever the currently active cell changes.

  Hello Irfan,

  Yes the upgrade option is gray when I opened the link. I'm trying to get my copy digital DVD that I bought (it came with a second dvd with digital copy). When I put the dvd in my computer tells me the following

  You upgrade the Windows Media Player security components to play the files on your computer. Upgrade, please follow the instructions below:

  • Step 1: Click here for the upgrade of security.
  • Step 2: After the upgrade is complete, click on the button 'Next' below.

  the link sends me to the next site http://drmlicense.one.microsoft.com/Indivsite/en/indivit.asp
  where the upgrade option is grayed and I can't click on it.

  When I go to the first link offers

  and I try to run the diagnostic tests, I am sent to a microsoft search page http://search.microsoft.com/?mkt=en-ca when I click on 'start the diagnosis '.

  I didn't update for windows media player 11 or windows vista. My laptop came with vista and I don't remember the windows media player upgrade. I am not redirected to a web page when I try to play back content protected by DRM. I'm unable to download an upgrade from microsoft, so I can get my digital copy.

  I'm sorry that I was not expressing the problem better in my original post. Can you give me more advice?

  Thank you

  ====================================
  I was wondering... When you insert the DVD into your player
  You can go to... Start / computer... and right click on the drive
  Letter for the DVD player is in and choose... Explore?

  If_yes_and you can see the directory of the DVD... try
  the digital version of the movie from there to a copy

• DMVPN with digital ceritificates and Hub acts as a CA server

  Hello guys,.

  is there anyway to configure the DMVPN with digital certificates and change the router Hub to act as a CA server?

  Thank you

  Yes, you can do it, go ahead and set up your router, Hub, with the normal DMVPN configuration so that it becomes the hub. After doing that follow the link below to add public key infrastructure server features:

  http://www.Cisco.com/en/us/docs/iOS/12_3t/12_3t4/feature/guide/gt_ioscs.html

  And to register for the rays on the hub, use this link:

  http://www.Cisco.com/en/us/Tech/tk583/TK372/technologies_configuration_example09186a0080210cdc.shtml

  Remember that regardless of the router Hub being the authority of CA, you must sign up for itself to allow the IKE PKI authentication.

• Interrupt with digital input

  Hello

  I am relative new to LabWindows.

  I have a program that starts when I press a button. The program controls a motor. Now I press a button on the motor and the program must cease (Safty Stop). The button is connected to a digital input on my card (PCI Express 6343). Now, I have the question, how do I program the interruption? I know not how do in CVI (controls the digital input whenever the program runs).

  I hope someone can help me.

  Best regards

  The starting point must be to look relevant examples that NEITHER provide:

  ReadDigChan - ChangeDetection.prj

  and

  ReadDigChan - ChangeDetectionEvent.prj

  However, I must advice against using a PC as a "Safety Stop". As a general rule, the PC are completely inappropriate to the core functions of security, unless you follow the standard IEC 62304 relevent to the letter. Tip: it's hard to do with a PC. To implement safety functions such as emergency and interlocks stops you buy much better a specialist dedicated safety relay and following the instructions of the manufacturer. If life-threatening energy (either electric or medcanical) may be present, then consult a professional engineer.

• Updated graphical waveform constantly with digital I/o

  I'm new to Labview and I try a digital waveforms graph to update in real time after the analysis of the data of a digital acquisition of data from input to output.  Is this possible or real time update can only be done with graphics?

  Hello

  Once, a very similar subject has been addressed in the forum of LabVIEW, where DFGray has responded to the following:

  1. You can use an XY graph generating X values yourself. This will ensure that you place the data exactly where you want it on the X axis. It's fast, but involves a cost of memory.
  2. You can use a chart of waveform with an entry of waveform instead of the cluster that you are using. Use the antiderivative of waveform to build instead of the bundler to make your waveform. Set the values of t0 on the appropriate values (negative work, as do the numbers - time is in seconds, using the primitive of timestamp to convert to DBL timestamp). Finally, you must set the graph of waveform to use the t0 values. Pop - up on the waveform graph and make sure that ignore the time information is not checked. Depending on your version of LabVIEW, you may need to appear on the chart or axis. When you uncheck ignore timestamp, you'll probably want to reformat the x-axis again. Waveform graph clears the data at each iteration, so you have to replot all your data every time. Just create an array of waveforms and keep to add. The t0s will waveforms in the right places. Yes, this can cause memory problems.
  3. Finally, you can use the waveform, that memory. Create waveforms as you did for the waveform chart and send them to the chart. He remembered what was sent to her from run to run. Make sure to set the length of the graphic history (pop up on the chart and select chart history length...) long enough to contain your data together. You can use a node property to retrieve the data at the end, if you wish.

• the analog inputs with digital edge trigger

  I am currently triggering a readout with a digital trigger using a 0 - 5v as the digital source encoder.  I am running LV 8.2.1 DAQmx 9.0 and a PCI-6259.  I use a VI I wrote and which is very similar to 'Acq & chart voltage-Ext Clk.vi', and using the one-pulse encoder connected to PFI8 as the clock source for the sample clock vi.  The only major difference is using the channel of the Z-trigger as a software reset inside the While loop with the DAQmx reading.  Currently, the sample clock doesn't allow that either read the lower edge or an increase of PFI8, so I get a sample by one-pulse.

  I need to double the rate of analog playback for a given tree rpm and encode them, so I need to read on the fronts and edges of the one-pulse encoder.  The sample clock can be reconfigured for the detection of changes and still read the PFI8 port to increase and decrease as inputs of physical channel, or do I have to configure detection of modification of the task/digital input for a single line and use the "ChangeDetectionEvent" as the source for the sample clock HAVE? Detection of Timing/change DAQmx can still use the signal in PFI8, or should I use DI ports, and which ports are DI should I use?

  Thanks in advance!

  In fact P0.8 is.  I was looking at the pinout for the 6251, no 6259.  Sorry about that.
