• Configuration of the basic Source of time to master for the 9234

  I have several cDAQ modules I use to collect data.  I use vi to Write can Express to save data to a file of PDM.

  When you examine the recorded data files, the measured data from NI 9215 provide pleasant timestamps to match how the DAQmx task has been set up--delaying the sampling frequency of 1000 with a 1 ms in the While loop.  However, although in the same vi - different tasks, but the same while loop - horodateurs of the NI 9234 do not correspond to the task of DAQmx implemented - sampling frequency of 1000 with a 1ms delay. After reading the material provided with the NI 9234, I found that maybe the machine clean master Timebase Source. There were documents that says he can be configured to be originally of Timebase of Master for the other modules:

  Configuration of the basic Source of time of the master for the NI 9234 (Interface FPGA)

  It is desirable to have the timestamps for data measured across all modules to match. We do not have the FPGA Module for LabVIEW. Is there a method in LabVIEW for all modules use the same master time base Source?  I assumed that because all the data collection has place in the same while loop by using the time delay of 1 ms it was forced through the code. This hypothesis seems incorrect from my review of the PDM data files.

  The NI 9204 provides a trigger only.

  Software:

  Windows 7

  LabVIEW 2010 SP1

  Material:

  CDAQ-9174 chassis

  Slot 1: NEITHER 9204

  Slot 2: NEITHER 9215

  Slot 3: NEITHER 9234

  Slot 4; Vacuum

  Hi MgDAQ,

  An important concept to note is that the 9234 uses a delta-sigma converter and a clock of oversampling to read analog data. There is an inherent delay of entry due to analog and digital filtering built-in. Since the 9215 has a lower resolution there will be a lag the 9234 and 9215 finished. I've included some resources below:

  What are the for the NI 9233, NI 9234, and NI 9237 valid sampling rates? : http://digital.ni.com/public.nsf/allkb/593CC07F76B1405A862570DE005F6836?OpenDocument

  Have you tried to put two modules in the same spot? Alternatively, you can export the sample clock 9234 and tasks installation separately.

• Close a non-LabVIEW with the LabVIEW program?

  I have two programs running on the same computer.  One is a 3rd party software that collects data from a sensor and generates files.  The other is a LabVIEW application that analyzes the files before deleting them.  (The 3rd party software is written in LabVIEW, but closed source).

  I want to stop the 3rd party software automatically whenever my LabVIEW application stops.  If someone stops the LabVIEW application without stopping acquisition of data on the 3rd party software, hard drive fills up with files in one day about.  Not good!

  Is this possible without turning off the computer?

  "kill Task" in command prompt will help you achieve what you want? Use systemexec in LabVIEW to do this. After the back if this is not what you want.

• Crash of LabVIEW with nodes of Boolean property

  I work with a set of Boolean buttons and when I call a node property for the button and try to set the class for the reference entry in a script of NI845X I2C or configuring LabVIEW 8.0 give me a tile of error indicating that:

  LabVIEW .exe has incountered a problem and needs to close.  We are sorry for the inconvenience.  I joined the main array with Boolean properties that I'm changing the class on.

  The main Boolean buttons are in a cluster and loop until one of the buttons is true.  While the index rose so I can retrieve the text of the button to bring the state machine.

  Jeff,

  If you can open the VI and go to the block diagram and one property buttons and right click on it.  Go down to "select class", NI845X, and then choose between the two choices of NI845x I2C.  Then once you have selected one of the two classes down the cursor down to the property select box below the error in and out and out property and config in.  Once my LabVIEW aura error within 5 seconds and then close after I click on the 'OK' button in the slab of the error.

  Try this and see if you get the same results.

  Gary

  What you do makes no sense at all!

  Why you try to change the property node of a Boolean control to a class of N845x?  We do not have this installed class, so we will not be able to reproduce your problem.

  You don't have any kind of reference wire connected in these property nodes.  If you did not have a wire of the correct class reference, then perhaps LabVIEW would know what you tried to do and would not crash on you.

  If you dropped an empty property node in the palette of control of the selected Application class, it always crashed on you?

  What happens if you have disconnected the chain wire coming out the property text node, then tried to change the class, it would break.

• clone then target trying to make contact with the source

  Hi all

  Some strange behaviour in the land of Oracle today...

  After a clone (managed, for the most part), we get alerts of the suite that tries to make the cloned instance of monitoring network contact with the source instance. As soon as I disable Apache alerts stop coming, so I'm halfway to understanding the problem.

  Can anyone think all the configurations that I missed? I searched the usual places (httpd.conf etc) any reference to the PROD, but nothing appeared. If Apache is somehow trying to contact the server of PROD, does anyone know where she can be configured?

  The connection between application layers - separate database levels are fine.

  Our version is 11.5.10.2

  The servers are RHEL 5.6

  DB is 11.2.0.3

  Thank you very much.

  (Autoconfig has run ok, everything works fine - just the annoying fact that I can't put back the environment yet!)

  DA

  Hard to say, but since the original question was in the Web server, it could be a separate issue. Still, it might be linked to the root cause. If you access another environment (on another server), it MUST be something.

  Preclone did run OK on the server database AND middle-ware? (on the source)

  Did you manually run FND_CONC_CLONE. SETUP_CLEAN? (on the target)

  Did you run the cmclean.sql file? (which could resolve the name of the source server in the managers of the conc.)

  What is in ORATAB?

• How to configure automation with Apple TV, Homekit and Hue

  I have what I believe should be a viable home automation installation: a new brand (4th generation, Sept. 16) Apple TV, a hub of hue with the support of Homekit and seven lights attached via the hub.  The lights appear in the home iPad app and can be enabled or disabled here.  I can also do things with Siri on the Apple TV as "turn one room family", and have the appropriate lights.  Thus, it seems that everything works.

  BUT: when I go to the tab "Automation" in the app iPad Home, all I get is a page telling me that I should get an Apple TV to put in place of the automated activities - there is no way to actually DO something.  Am I missing something obvious?  I do this also?  Don't forget that I can control the lights in the House on the iPad, so they certainly know each other...  Thank you!

  Looks like you are unable to configure Automation with your Apple TV. I would check that you have everything set up correctly with the steps described in this article:

  If everything looks OK, then use the section 'Get help with your home hub' down. Thank you for using communities of Apple Support.

• With the help of LabVIEW with NI VeriStand

  Hello

  I try to use Labview with NI Veristand, when I followed the white paper here:

  http://www.NI.com/white-paper/11135/en

  I do not see the same menu detailed in step 4 (OR veristand is not listed on the menu - see attachment). I have NI Veristand installed on my computer.

  Do I need to install an additional extension?

  I'm using LabVIEW with version control and only want to check the VI I need to change. If I changed a Subvi all screws directly or indrectly called this VI have recompiled and in order to save them, I need to check all screws are concerned.

  You can view the example where x, there are controls

  There is a more detailed guide here, I reference below:

  1. first of all, you can enable it in settings:

  1. open the properties for a version of the application specification

  2. navigate to the Advanced category

  3. check the pass all arguments on-demand command line

  To pass the arguments to command line to request and access in your code follow the same steps as for LabVIEW 7.x.

• How to open the labview with function of Labview program to stop smoking inside?

  Hi any idea how to open the labview with the Labview function program to stop smoking inside?

  I forgot to add and define the condition of the type for this program.

  If the program is an application, she closed immediately.

  If it is still the work of labview, it will go directly to editing without closing the program.

  I so need to retrieve, open it and make some changes.

  Place the VI in a project and open it from there, then it should not autorun. App.kind application property allows you to decide whether to close or not.

• Beginner question absolute to the Labview with GPIB connection device

  Hi all

  Firstly, sorry if my question is already posted, but I tried searching with nothing doesn't.

  My situation: I have a HP digital osciloscope, a HP 54602 B using the GPIB and trial version of labview 8.6. Now, I want to communicate with her from labview. The big question is: how? Before that I used only labview with NI DAQ card and serial port for communications of the instrument.

  the detailed question

  1 is it important (to programming in labview later) what GPIB interface that I use in my computer? Must be of OR? I still have no interface right now.

  2. I ran a search on the osciloscope Web site of NOR and find an instrument driver in:

  http://sine.NI.com/apps/UTF8/niid_web_display.download_page?p_id_guid=E3B19B3E93F7659CE034080020E748...

  . How do they come?

  3. I know there are a few examples for the GPIB, but since I do not have the interface, I can't try it. Is it possible to simulate instruments GPIB?

  Thanks for all your help and assistance

  Hi opiq;

  Welcome to the world of instrument in LabVIEW Control!  I'll try and answer your questions one-at-a-time:

  1. N ° from a point of view of LabVIEW, you can use any interface supported by VISA and your instrument bus.  This includes (but is not limited to) boards of NOR-GPIB, 3rd-party GPIB, USB, LAN, LXI, VXI, PXI, etc..  Of course, if you do not have a GPIB interface, I would recommend a NEITHER - this is the safest way to get the experience 'it works '.  I tend to use an adapter USB GPIB (DISCLAIMER - I work for the OR).
  2. You have two options for installing the device driver.  "" The simplest is in LabVIEW to select Tools "Instrumentation" instrument Drivers find... and use our instrument driver search tool which will be step helps you locate, by downloading and installing the driver.  The other option is to download the zip file, unzip it in \National Instruments\LabVIEW 8.6\instr.lib and restart LabVIEW.  So if you look in your palette of instrumentation, you should see the driver listed under instrument drivers.  The pilot will include some examples of the use of the driver (are all certified instrument drivers).

     In fact, I would recommend this driver rather than that you connected.  It is a more modern design and install examples in the viewfinder of the example ("Help" find examples...).

     Here's a video of the above process (for a different instrument, but the process is the same)

  3. Unfortunately, there is not an easy way to simulate this instrument.  I would just recommend familiarizing yourself with the examples before acquiring a GPIB interface.
