• synchronize the inputs and outputs on the USB-4431

  Hello

  I have an application that needs to send a signal on the USB-4431 and then capture it with an entry on the same device.

  Aware that I use two tasks to do this, one for input and one for output. I discovered that a trigger (on the RTSI bus) can cycles of sending/capture sychronisé departure operations so that it can be a constant offset between the captured signal and the output signal.

  Unfortunately, the code I found is for Matlab. I can't find an equivalent for it in the C API of NIdaq. The method is described here; http://www.mathworks.in/help/daq/synchronize-analog-input-and-output-using-rtsi.html.

  What I can't understand is how to implement this on the analog input:

  ai.ExternalTriggerDriveLine = 'RTSI0';
  

  Can someone shed light on how to do it?

  The rest of the things described here, seems to be feasible with a normal trigger:

  ao.TriggerType = 'HwDigital';
  ao.HwDigitalTriggerSource = 'RTSI0';
  ao.TriggerCondition = 'PositiveEdge';
  

  Thank you

  You can synchronize the HAVE and AO by sharing the start of relaxation between your two tasks.

  Choose one of your tasks as the "master" and the other to be the "slave" (any).

  Set up a trigger to start of digital dashboard on the task of the slave, and set the source of the trigger to be the trigger of the master's departure.

  Assume the following:

  The name of your device is 'Dev1 '.

  I is the main task

  AO is the task of the slave

  Here's what you would do to sync the two:

  (1) create the tasks I and AO in order that you want to

  (2) set up "timing" on the tasks of HAVE it and AO (you choose the sampling rates must be the same or power-of-2 many of the other (for example 100 K, 50 K, 25 K, 12.5 K, etc...))

  (3) configure your slave (the task of AO) task to have a numerical advantage start trigger and make the source is the trigger for the start of the task of the master (the task to HAVE it). In our case, "Dev1, AI, StartTrigger.

  (4) write data (a sine wave, presumably) to your task AO

  (5) start the task from the slave (the task of AO).  The task of the AO is now in the 'Started' State, but given that you've set up a digital trigger early, it won't actually generate data until he sees a numerical advantage of 'Dev1, AI, StartTrigger.

  (6) to start the main task (task to HAVE it).  The task of the AI does not have a trigger digital early, so the software will immediately generate a start trigger, which also causes a numerical advantage on "StartTrigger/AI/Dev1", which causes the task AO start at the same time.

  7) read your job to HAVE.

  You will notice a few 0 at the beginning of your data to HAVE. It's a result of something called "Filter Delay" and it is an inherent characteristic of all DSA devices - see the manual to use DSA and this article for more information on what is and how to cope.

  I hope this helps.

  EDIT: I just noticed that you pointed out an existing C example. It's exactly what you want. I don't know why you have a resource error booked - I tried it myself and (after changing the AO will of +/-10V to +/-3 .5V), it works beautifully.  Try to reset your device to the MAX (or DAQmxResetDevice() of your program)

• Synchronize the Photos and iPhoto?

  Photos arrived it imported all my photos in iPhoto. I have not really used pictures so far and now I realize that my library in pictures is a duplicate of my iPhoto library, except that they are not synchronized. My iPhoto library is updated, every photo I want is removed. This is not the case with Photos. Is there a way I can synchronize the two apps so that the pictures is exactly the same as iPhoto is now? Now iPhoto and Photos together use more than 100 GB of space, when in reality I have about half of it in photographs.

  If I can't sync, deleting photos in one application will not delete not them on the other, correct? In other words, I can delete all photos of Photos without deleting my photos in iPhoto, right?

  I have pictures 1.0.1 and iPhoto 9.6.1

  Thank you

  When you open the Photos first, the migration of the iPhoto library and photos of 2 libraries are hard linked to where they do not place additional, even though both show a large amount of data. However, from there, they are treated separately with respect to the addition or deletion of photos.

  You cannot synchronize the 2 applications. They are distinct and have nothing to do with one or the other.

  So, you might want to simply select the one you want to use and go from there. I guess that iPhoto is gradually thereafter. Photos will be more integrated into the system as well as for tasks such as sharing in emails, adding photos to apps like mail and so on.

  Yes, you can remove some or all of the photos in one application and does not affect the other.

• Implement and control 'meter' in S7 - 300 by the OPC and LabVIEW

  Hello world

  I use a S7-300 PLC and OPC Server for my projects. I have a problem: S7 - 300 has a meter module which digital signal of County. I only can implemented using SIMATIC STEP 7. Can I set up the meter module using only the server OPC and LabVIEW

  does anyone have a solution or an idea for my problem?

  could you please help me...

  Thank you

  Hi Echion,

  NOR-DAQ (MX) is used only for material OR: no you can not use it.

  To program the controller you must use the right programming environment. For Siemens S7, you need to use Simatic (or perhaps some other 3rd party software supporting IEC61131). Point.

  The OPC server is used only for the exchange of data. This is no interface programming!

• Is it possible to synchronize the SFDC and Eloqua users?

  I know that I can create an automatic synchronization to download SFDC users; However, it is not a user Table in Eloqua (Eloqua customer s US have access, in any case). I guess it's impossible?

  This would be really useful for the creation of new sellers in Eloqua on the fly, their updating, deletion, when they left, etc.. With Salesforce.com being the registration system, this reduce manual processes, clean the data and effectively enable and disable users. Still, this would allow Signature rules for customization of Email to bring more quickly.

  We are of course we can not synchronize users? I created in an AutoSync yesterday and noticed the ability to import into a table "users" Eloqua. Here's the Eloqua dashboards and not Salesforce ones (Contact, company, Outlook, data cards, etc.). See the screenshot below...

  It does not sync DB to the model or model DB:
