Real-time synchronization works in versions of oracle 8i?

• Is there a tutorial for creating executables in real-time?

  I have the code in real-time which works OK in LabView (not the final version no doubt but I need to learn two or three other things as well).

  Now, I would like to create an executable file that I would run on some PCs with some inside monitors and control.

  I found little exercise on the development of Application (shortly): 1) create shared variables) 2 create a copy of the Vi that works and to replace the controls and monitors in it with static variable) 3 Windows creating welcome 4 VI) probably create an executable after that (step not described in the exercise).

  I'm currently stuck at step 3 with the 1950679035 error.

  Looks like a well known error, but I found no solution yet.

  My question is: which is the right way, I'm moving to? Or there is another way to create applications with control and monitoring of the device in time real NIcRIO 9072?

  Hi Sergey,

  Glad to hear that you are making progress.

  And all you need to do now is create the façade in the same way that you would create a normal .exe file.

• Apply real-time: delay is ignored

  Hello

  I am trying to set up a standby database can be found in paragraph 12.1, but apply in time is always activate.

  Of the primary database, I always see in the alert.log:

  WARNING: Managed Standby recovery started by APPLYING in TIME REAL

  DELAY of 60 minutes ignored elementary

  Same database alert.log emergency exit:

  Managed Standby recovery started by APPLYING in TIME REAL

  Specified previously ignorant DELAY 60 minutes for the sequence of thread 1 169

  Archived newspapers is copied on standby but applied immediately. Delay of log_archive_dest_2 is ignored. Why?

  For the moment, it's OK. Even when you don't plan to use RTC, you always rely on other services of the hive. For example, a future conference planning requires time management Service. There are a few things we can do to simplify things in the future, but those who are more long term.

  Hope that helps,

• How do you download a newer version of time Labview real-time in PSC-2200 when is not not in MAX?

  I can't figure out what I need. My PSC 2200 has a version of Labview RT 8.5.1 and fieldpoint 6.0.1.

  I need to be at least RT 10.0 Labview and fieldpoint 6.0.7 because I do Ethernet IP. I don't know that anything more recent that it will work as well.

  As far as I know, I downloaded fieldpoint 6.0.12 and I have the Labview RT 10 module. What Miss me to update software on the cFP-2200 by MAX?

  I don't know another software in the software other than what is currently installed real time Wizard.

  

  Software shown MAX:

  

  Any help is appreciated!

  Thank you.

  Wow, Fieldpoint 6.0.1 was released in 2008 - which has been in the LabVIEW 8.5.1 / 8.6 times.  If you want to use LabVIEW 2010RT, you really need to upgrade.

  Try to download and use Fieldpoint 6.0.11: http://joule.ni.com/nidu/cds/view/p/id/3073/lang/en

  LabVIEW Real-time is not "natively" delivered with Fieldpoint or cRIO supported, these happened as part of the RIO or Fieldpoint support modules (so that the most recent versions of RIO or Fieldpoint update your support).

  Who give a shot!

• Real-time application does not work; source code works very well

  The short version is I'm programming a cRIO and apparently the RT code isn't running after you deploy, and I can't understand why. It is further complicated as I do all this remote and I don't have direct access to the unit since I am 500 miles away. I work through a couple of other guys who know some LabVIEW, but neither is working on the site so that they explicitly trip there whenever I have a bright idea.

  I was there a few weeks ago. During this time, I created a code simple cRIO, since I'm new to the cRIO, allowing the user to move a control and change a chart. It worked fine, but I must stress that it did not have a FPGA component. After that, I worked on the actual code, which reads some sensors, displays the results on a user interface and stores the results. Did FPGA. I used it in the LabVIEW environment and it worked fine, but I ran out of time before I could finish a release build and deploy the RT as a compiled application. I sent them the version later, my contact deployed but had the network stream errors during execution of the user interface.

  After hours to address network problems and sending over debug versions, I tried to create a log on RT level so I could see what was going on. The journal is not yet open, even if it is the first command in the code. I have pores through the forums and found http://forums.ni.com/t5/LabVIEW/cRIO-Troubleshooting-creation-and-deployment-of-startup/td-p/1956475... which took a new direction.

  I had my contact use the RT debug console and when it pulls up to the front of the RT, it shows an arrow broken at delivery. He clicked and nothing happens - no work, no list of bugs. If he shoots to the top of the list of bugs manually, it is empty. Again, the RT works very well if you run it through LabVIEW and not as an application compiled in real-time. He also noticed that the open FPGA VI was grey on the block diagram. Are no other icons.

  If the problem seems to be that the compiled application of RT becomes some kind of error, but do not tell me what it is, and it seems to be related to the opening of the FPGA. I recompiled the FPGA and RT. I recompile the RT himself, but not the FPGA, because this would take hours. It is download everything properly for the cRIO. The RT is set to run automatically. It is restarted the cRIO whenever he deploys the RT. They have LabVIEW on a computer, but it doesn't have the correct drivers to run the code of the environment of LV. I am to resist have them install the dirvers because downloading big files is complicated due to the restrictions of security as well as a lousy connection at a remote site. In addition, it does not solve the problem of RT executable doesn't work is not the same as the source code, which, according to the thread above, seems to be a thing.

  The last thing I'm getting is that I sent her instructions for how to build a source distribution of the project that I sent and try to deploy on the cRIO. Even if it works, I'm not sure that this is an acceptable solution, because I assume running VI, rather than the EXE is slower, and they need to speed on this project.

  Simply, I don't know where to go from here. I probably need to get direct access to the cRIO and I might be able to convince them to ship to me so I can understand this point, but I don't know where I got same departure other than the Voodoo debugging standard of "trying stuff randomly until something works". I am open to suggestions, if someone managed to solve this before.

  Code snippet of the first part of the project is fixed, although I don't know how much what good it will do. I am really confused, and the customer is frustrated with how much budget is going to solve this problem.

  
  

• Not able to work in real time.

  
  RTA,

  I'm working on a PC, Windows 7, operating system 13, version 348.07 of the K2000 Quadro video card, 32 GB and 64-bit memory. My videos will not work in real time on this new computer. It installed fine and I can see all my videos and graphics in the timeline panel, but when I play the video it does not play, I created. It remains on the first image. My video card is causing the problem?

  Good to know of your success with 13 items first. If you do not already, update 13 to 13.1, by using a project open Help Menu/updates to date. First review

  First Elements ATR troubleshooting: EP 13: updated versions of Adobe Premiere elements 13.1

  Sorry for the delay in message exchanges. I think that your son is lost in the traffic of thread.

  I reread your thread earlier, and I wonder if the success with 13 were related to wake up a computer using a card video/graphics NVIDIA's first Elements 10. The specific issue of first Elements 10/NVIDIA GeForce is well known. But I wonder if there is a similar first Elements 10/NVIDIA Quadro specific question as well? Then the answer would have been to the

  a. roll back the version of the driver

  b. go to a later version of Premiere Elements

  c. change the graphics card on the computer

  Anyway, the good news is that you move forward with your Premiere Elements project. Always big news.

  And, please let us know the results and stay with troubleshooting. Great job.

  Best wishes

• Oracle JRockit 3.1.2 and weblogic real time?

  http://www.Oracle.com/technology/software/products/JRockit/index.html ". I go to the site and find a software called: Oracle JRockit Real Time 3.1.2 for windows 64-bit. My question is: in order to let weblogic 9.2 works in windows 2003 R2 64-bit computer, DEVRAIS I MUST DOWNLOAD "Oracle JRockit Real Time 3.1.2 for windows 64-bit? Or I need to download anything? In fact, I just downloaded a file called jdk-6u18-windows - x 64 .exe. Please delete my question, thanks! One last thing, what is the feature in real-time for Oracle JRockit 3.1.2? Is it a kind of JRE?

  If you are looking for better performance with WebLogic then it may be worth going with the JVM JRocket.

• UDP playback does not work on a real-time target

  Hello

  I am running LabVIEW RT 8.6.1 on a PXI 8106 RT controller.  LabWindows/CVI for RT 9.0.0 execution engine is also installed that I develop using LabWindows/CVI 9.0.  I'm trying to send some data UDP for an external PC via the network for software running on the controller, but this does not work.  The UDP packets are certainly get sent (I receive on my PC when the transmitter to reconfigure my PC IP address) but the UDP callback function is not called.  The call to CreateUDPChannelConfig returns OK.  Here's the (very simple) code that I wrote based on the example of reading NI UDP:

  #include 
  #include 
  #include 
  
  // Global variables
  static int reader_channel = 0;
  
  // Global functions
  int CVICALLBACK UDPCallback (unsigned channel, int eventType, int errCode, void *callbackData);
  
  /// HIFN The main entry-point function for the Real-Time DLL.
  void CVIFUNC_C RTmain (void)
  {
      int errno;
  
      if (InitCVIRTE (0, 0, 0) == 0)
          return;    /* out of memory */
  
      // Create UDP receive task
      errno = CreateUDPChannelConfig(49152, UDP_ANY_ADDRESS, 0, UDPCallback, NULL, &reader_channel);
  
      while (!RTIsShuttingDown ())
      {
          SleepUS (1000);
      }   
  
      CloseCVIRTE ();
  }
  
  int CVICALLBACK UDPCallback (unsigned channel, int eventType, int errCode, void *callbackData)
  {
      static int udp_received = 0, default_rx = 0;
  
      switch (eventType)
      {
          case UDP_DATAREADY:
              udp_received++;
              break;
          default:
              default_rx++;
              break;
      }
  
      return 1;
  }
  

  All that happens is that software is just waiting for the callback to be called (which never does).  I found this ad that described a similar problem, but the developer was using LabVIEW and although he has found a way round the problem, he was never heard as to why it worked.

  Thank you

  Martin

  Hey,.

  Although the problem is now resolved, I thought that put the code for others see if the same error is encountered. The modified code is tested and works. It is saved as an attached png file.

• How can work in real-time my vi?

  Hello

  I have a vi that use a lot of loop in loop (as 128 * 128) in there.
  and to use an equation (contains: n! & gamma (n)) on this subject.

  It works fine but the problem is: when I click on the thumb, it takes about 1 second to respond to be broadcast.
  but I want to run in real time. and want to meet be ready less than 50 ms.

  What is the problem? and what do I do?

• Structure of the timed real-time event loop does not work

  I'm a new user for LabVIEW. And I've encountered a problem that frastre really me! Hope someone can help out me. Thanks in advance!

  I just want to use the structure of the event under timed loop, which is important in my extrmely design.

  However, this works very well in my computer (without connecting to the FPGA).

  Once I connect it to the FPGA, then I can still run but there is no response!

  My file is attached. Please someone help me!

  Looking forward to your answers!

  The FPGA runs headless. Structures of the event won't work. What you need to do is to have an application on your host computer when the user presses a button, changes a value, etc.. This event should send a message via TCP/IP for code that runs in real-time environment. Then the real time environment should attribute to the desired value a control on the FPGA.

  As a general rule, programming real-time with FPGA has several layers.

  (1) host-> handles interactions with the user code and communicates the code in real-time via TCP, UDP, etc.. Displays the user sent by RT controller data.

  (2) code in real-time-> tracks headlessly. Manages host code messages, processes the data of FPGA, communicates with FPGA much as the host code communicates with the code in real-time

  (3) FPGA-> no acquistion and passes through PEP in the RT

  The first thing you need to do is to understand the architecture and how all these pieces of the puzzle work together before you throw things down on a diagram.

• "1 MHz" for the name of the source on the time loop does not work on LabVIEW Real-time 9.0

  A Loopis Timed running as expected if a time source is manually chosen in the dialog box of configuration for "1 kHz" (first digit) and "1 MHz" (second digit). If the time Source name is set through the input of the channel "1 kHz", the loop is executed, too third figure). But if the input string is "1 MHz", the loop is not executed (last figure). The channel two are created by "create constant" on the entry of the loop to exclude typos. Is it possible to set the Source of a loop time timed through the input string to the real-time clock hard Mhz?

  

  

  

  

  OK, I was a bit confused by the difference between the behavior of error...

  Now, the question is quite clear. Aid for the timed loop provides the following regarding the Source of the calendar entry:

  Specifies the name of the synchronization source to use to control the structure. The source of synchronization must be created using the create synchronization Source VI on the block diagram or selected in the dialog box Configure the timed loop .

  So, I think that you have somewhere in your code a time Source.VI create if you pass "1 kHz" as the name. But you did not do this for your clock "MHz 1"...

  hope this helps,

• cRIO and 9234 modules do not work or communicate via fpga with accelerometers, fpga, connected to the real-time application is also related to shared variables related to modbus slave

  Hello

  I have a compact rio, which has a 4 way frame this chassis is the three modules of ni9234, they are related using FPGAs for application in real time, then using shared variables in the low-speed loop associated with a slave modbus to communicate with the domain controllers, the nor 9234 accelerometers linked to them with option ac coupled iepe on c modules , my problem is the real-time application seems to work well even when power loss occurs it restarts without problem and the fpga written hard disk portable bin files very well, but without an accelerometer connected I get readings of low noise as soon as I connect an accelerometer to one of the outputs 10 it just goes to a fixed number (0.03125) as soon as you unplug it again He returned to readout noise, I ran a scan on the modules and get only a spike when I connect or disconnect the accelerometer, I tested voltage at the pins on the module and I get 22 volts CC which makes it more likely that the material is not the problem, but software is perhaps the cause to hang up, I join the project and files for your perusal. I also realized a new project which, in mode directly linked scan has the module entry in the shared variable and the scenerio even once again. Help would be appretiated.

  Thank you very much

  Whren using waveform with the 9234 acquisition, we recommend the following FPGA and RT model.

  http://sine.NI.com/NIPs/CDs/view/p/lang/en/NID/209114

  It can be extended as a datalogger with:

  http://zone.NI.com/DevZone/CDA/EPD/p/ID/6388

  or using shared variables combined with the analytical engine

  http://zone.NI.com/DevZone/CDA/tut/p/ID/9851

  The FPGA in all this, as well as the framework of RT have used successfully by 1000s of users.  I recommend giving these a try.
