• Pulse counting with USB 6008

  Hello world!

  I have a project with USB 6008. I want to count impulses (for special features: count the pulses of the encoder) use USB 6008. I wirite with DAQmx to test a simple. But it do ' t run. Please see and help me to do this exercise. I just borrowed 6008 USB so I don't have any experience with USB 6008. Thank you! It's funny.

  Looking at the PFI0 manual (pin 29) is correct and I don't see anything wrong with the code and example should work. I have a M-series card, not a 6008 and it works for me. This error code is meaningless if. Are you sure it's the number?

• How to use a proximity sensor to turn on a servo motor?

  I use a proximity sensor to locate and count an object because it oscillates.  As the reference voltage changes that I need change the position of the servo motor.  I have developed individual programs, one for the sensor and operate the servo motor, but I have problems combining the two programs.

  Attached are the two programs.  Are there recommendations on how to combine the two programs?  I use a DAQ 6210

  Herriott,

  I have attached a LabVIEW project that combines the two screws. They are combined in such distance that the servo 2 vi is called whenever you add one to the count in the Tack.vi of proximity counter. For more information about how to do under VI, please visit the links in the previous posts on this thread. Again, I'm not completely sure of how you want to control the servo, but this should get you started so that you can change the project to meet your needs.

• count between two dates.

  Dear friends
  I want to search count between two dates.
  my query is like below.
  SELECT (to_date('19-mar-2012','dd-mm-yyyy')-to_date('01-apr-2012','dd-mm-yyyy')) DOUBLE
  
  It is as given to-13, but I want in positive mod as not only 13 '-' Sign.

  Simply use the function abs() to your query to get the positive value

  SELECT abs(to_date('19-mar-2012','dd-mm-yyyy')-to_date('01-apr-2012','dd-mm-yyyy')) diff FROM dual
  

• Capture high speed encoder data

  Hello

  I have a motion control project where I would record the position data. High speed capture is limited with sampling frequency of 2 kHz. But I have to save a lot more than higher speed.

  I read that there is another option that connects to the motion control card (I use a card PCI-7358) and the map of data acquisition using a RTSI cable and channels A and B of the routing of the data acquisition card encoder using the RTSI lines.

  I have 6143 and 6280, 7358 PCI DAQ cards and a RTSI cable.

  Q1. Which card is better to use? 6143 or 6280?

  Q2. When I look at the examples, I have seen that its possible to phase has the traffic and signals of the phase B of an encoder for the RTSI line with Signal Select.vi. But I couldn't find an example on how to read of DAQ card.

  Q3. How can I contact the encoder position phase has and band B pulses which is acquired from the DAQ cards?

  Concerning

  Hi serkanb,

  The 6143 has no support for measures of encoder quadrature (although you can run a task of count of edge and use the B signal as a line up/down to get a similar effect).  If you are interested, we'll find more information here (the 6143 uses the same SC I ASIC that make the E Series DAQ devices).

  It doesn't really matter too much since you have a 6280 that supports quadrature encoder measures (he uses the STC II ASIC).  To answer your direct questions:

  Q1.  The 6280 is better (see above)

  Q2.  You need to use a channel DAQmx property node to choose what terminals to use for your task of encoder:

  

  Q3.   I would like to start with an example of the expedition:

  Help > find examples... > input and output material > DAQmx > counter measures > Position > measurement Position.vi

  You insert the property node before starting the task (but after the channel is created).

  I hope this helps, if you have any questions do not hesitate to post back!

• Erratic counting quadrature encoder

  Hello

  I try to use LabVIEW 9.0 and an acquisition of data USB-6212 for measuring angular displacement of rotating quadrature encoder (digital model we E2) attached to a linear actuator based on the stepper motors.

  With the help of the VI linked to below and the default PFI pin on the acquisition of data, I can get the Angle of the VI to change, but with two issues indicator.

  http://forums.NI.com/attachments/NI/170/144774/1/QuadratureEncoderM-series.VI

  1. the only way I can assure you that the Angle indicator remains at a constant value with the VI running and the stepper motor moves do not is to turn off the power to the encoder.  In other words, when the 5V power is provided to the encoder, the Angle indicator sometimes remains constant at a certain value and sometimes increases, even if the motor step does not move.  I added a waveform table that displays the Angle to see more easy output.

  2. with the engine not to not pass any if she moves hourly or counterclockwise, the angle indicator only increases (counting).  Changing the direction of engine displacement does not decrease the angle.

  I checked the DAQ pins I use: PFI 3, Z = A = B = 11 PFI with ctr and PFI 4 1.  I tried both ctr0 and ctr1 with the same results.  I used a multimeter to check the outputs a, B and Z on the encoder to output with the motor step-by-step to displacements of various populations, and I'm getting ~ + 5V sometimes and ~ 0V sometimes telling me that the encoder, which is new, seems to move from high to low.

  This sounds like the kind of behavior that may be caused by noise in signals?  If so, who should not have something to do with the Angle only, correct?  To get the Angle to reduce, should I change something in VI?

  I thank you very much for any assistance, you can give.

  Hi Mike,.

  From what you describe, I feel the symptom of the meter backwards never is a side effect of the issue where the meter continuously counts up while in not moving.  This really looks like a noise problem, and there are a few small but noticeable spikes in your graphics HAVE you provided.  Basically, as long the (Source) Signal led B Signal (to THE), then the meter progressive count.  This is for X 1 coding, which I assume that you are using.  Look here Figure 5, in virtue of the X 1 section for how this encoding reads your signals of encoding:

  

  Your connections you describe are correct, so it'll be a matter of getting rid of the problem where the meter is incremented on its own which I believe will solve your other problems.  Take a look at these links to see if adding filters on the internal counter inputs to the card allows the measurement: Activate the digital M series filtering  allowing digital filters for TIO Debounce NOR-DAQmx devices

• Pulse count continues

  Hi, I have a digitizer PXI-5152 to two channels, one for read the voltage signal and the other to read the current signal to an electric discharge machining (EDM) process.

  I want to count impulses generated in the process, for the moment, what does the code was the first to acquire number of data points and then pause to process data in a while loop to count the pulses on the rising or declining aboard trigger. The reason to do this is also some information of the data points are extracted in the while loop. But this way, I can't count all the geneated of legumes in the process because the acquisition and break the cycle.

  Is it possible that I can write a code only permanently count impulses (rising or falling edge trigger) during the process? The process can take more than half an hour and number of generated pulses could be a few million?

  Or do I need an additional card for the purpose?

  Any help will be most appreciated!

• How do I change the date on a lot of photos with the built-in date wrong

  My camera date was wrong for about a month (a few hundred photos and a handful of 'events').  I know how to adjust the date for an image both in Photos Version 1.5 (370.42.0), but I'd like to change for a lot of photos at once.  Can is it possible, you tell me how?

  If you select the bunch of incorrect pictures, and then open the tool "Set the date and time" in the menu, you can adjust the picture in the window at the right time and date, then click on adjust and all other photos will be adjusted to the same amount of time (not at the same time), this must be what you want to do.

• Servo motor RC directly from sbRIO e/s digital

  Hello

  I would use a Committee sbRIO to fly a RC servo.

  A RC servo control is usually reading a signal modulated TTL level pulse width.

  Calendar will be no problem in using a sbRIO, for the FPGA can manage that.

  But I am concerned about the level of output voltage of the output digital sbRIO; High level, it is specified as being > 2, 7V (max 3, 3V). It seems to be ok with the high level of TTL level requirement, but I wonder if anyone has tried this.

  Thank you very much for comment, that you will have on this subject.

• Script to get VM list and count on the data store

  Hi all

  I have a script of lining that gives me the number of virtual machines on the data store, I was looking for both number of virtual machines more VM names too.

  Get-Datastore. Select Name, @{N = "NumVM"; E={@($_ | Get - VM). County}} | Sort name | Export-csv-path "C:\Users\userA\Desktop\Cluster_Host_Report\datastorevmcount.csv".

  the above script gives not only. or the number of virtual machines on the datastore in VC, can we get that all virtual machines are there on the VC data store.

  Thanks in advance a ton.

  The ForEach loop do not place anything on the pipeline, you can fix this with the call operator (and)

  & {{foreach ($ds in Get-data store)

  Get - VM - Datastore $ds |

  Select Name,

  @{N = "Datastore"; E = {$ds. Name}},

  @{N = "VM on the data store"; E = {$ds. ExtensionData.Vm.Count}}

• How to count the continuous dates in oracle 11g

  Hello
  
  I need to count the continuous more than 9 days between given dates below is my example
  
  Are my data like this
  MAY 1, 2013
  MAY 2, 2013
  MAY 3, 2013
  MAY 4, 2013
  MAY 5, 2013
  6 MAY 2013
  MAY 7, 2013
  MAY 8, 2013
  MAY 9, 2013
  MAY 10, 2013
  
  Now I want the number of days between these continuous days of more than 9 days now, I will get the result for the above data is 10 days
  If any date is not in the list then days would not result if it is less, then are equal to 9 days
  Here is an example of another
  MAY 1, 2013
  MAY 2, 2013
  MAY 3, 2013
  MAY 4, 2013
  MAY 5, 2013
  6 MAY 2013
  MAY 7, 2013
  MAY 8, 2013
  MAY 10, 2013
  11 MAY 2013
  
  number of days here is 10 but may 9, 2013 is away at the moment, the county should not show as 10 because continuous date (May 9, 2013) is absent, that's what I need, please suggest the solution.

• Smart album, creating criteria of dates wrong

  Created smart album criteria evil in Danish local range - it uses silently JJ/MM/AAAA while displaying the DD/MM/YYYY.

  In the Danish version of Photos, dates are displayed JJ/MM/AAAA (photos) which is correct. When you create a new smart album with a date range of, say, 12/01/2014 to 01/01/2015 I spend January 1, 2015, obviously erroneous, 12 January 2014.

  Thus, the error is that dates are displayed correct for the locale, but the entrance to the date range in the creation of the smart album is in the order of US.

  How to fix this?

  FYI: I am reposting this question who hails from 2015 because there is no immediate solution.

  Best

  Alexander

  Try to use two separate rules:

  All the

  Date is later than

  and

  The date is before

  For the date range.

  And send your feedback to Apple for repair - use this form: Feedback - Photos - Apple
