• NTP synchronization drop Linux Compact RIO

  Hello

  I followed this method of synchronization with NTP (https://decibel.ni.com/content/docs/DOC-39178) and it works most of the time, but sometimes, I lost the NTP synchronization and crio are about 7 s forward. (I get the problem with a 9035 and a 9068).

  When synchronization is no longer works, Pei ntpq command responds "connection refused".

  Does anyone have an idea about the problem?

  Thank you

  Hello Jacques,.

  Sorry, I wasn't very clear

  Before you add the ntp-utils, I lost the synchronization several times: sometimes after a few days, once, after more than 2 weeks, but also sometimes on startup, I was not able to sync

  Given that I have install ntp utils, 10 days earlier, on 5 compact rio, I run the of-p command ntpq every minute and I always get a response, then that means I never lost the NTP synchronization (or I lost it less than a minute). I will continue to monitor them, but it seems that ntp-utils has helped me as weel

• Compact RIO NOR-9082 Configuration in MAX, cannot save

  Hello world

  I tried to implement a new cRIO the NOR-9082. Currently, I am able to see the cRIO under "Remote devices" in MAX configuration and view. However, the two errors that are produced:

  (1) when I try to change the setting as the host name and press 'save' a warning appears saying: "there was a problem, save the settings of the target. Make sure that your material is under tension and hat it is connected to the network. I have attached a picture below.

  (2) at the same time, when I try to install the software on the cRIO by double-clicking on 'software' and selecting "Add/Remove software" and run the Wizard "LabVIEW Real - Time Software", another error is displayed: "error: the disk hard n the remote system is complete or encountered an i/o error." I've also attached a picture below.

  The cRIO is lit with "DISABLE RT' toggled OFF. It is connected to the network via an Ethernet cable. This connection seems fine, however I look. (The connection of Ethernet port light flashes continuously activity indication etc..) It is the PC that is connected to the same network, I'm trying to interface with the cRIO. The cRIO displays the right IP address assigned through the network.

  My apologies if I have not provided enough information to solve this problem, but if someone might be able to explain why I could meet these two problems in these circumstances, assistance would be much appreciated. Thank you!

  It seems the main reason I got all these weird problems, it was because the compact RIO NI 9082 can come bundled with windows 7 and LabVIEW 2012 SP1 preinstalled and run as stand-alone computer so all I had to do was plug in a VGA to a screen and a mouse USB, keyboard and an eithernet for network connection cable and he started very well. Now, development and deployment happen locally on the cRIO. It was a little silly to me, so hope that helps someone!

  Kind regards

• touchscreen compact Rio

  Hello world!

  I'm developing an application to control a cooler with Labview 2012 and Compact RIO. I would like to create a group of GUI to visualize data and a basic control.

  However, I would like to use a touchscreen to third party (not OR). Purchase the Labview Touch Panel module can I do?

  My question is: if it's just a screen and not a PC, simply by connecting to the RIO Compact RS232 port and launch of real-time application,

  It will allow me to control the VI?

  Thank you!

  I don't see why not.  You need to just make a protocol of good communications between your cRIO and computers touch screen.  I find a network stream to work very well.

• Emular / Simular Compact RIO

  Hay alguna manera trabajar o hacer simulando Québec tengo el RIO Compact the tests? Ocupo hacer unas secuencias, pero aun no tengo el RIO Compact how.

  Yo as recuerdo con las Renault suckers hacer tus VI y poner una virtual DAQ, is you can hacer algo parecido? o para trabajar con screw in Compact RIO is space forzosamente tenerlo how?

  MUCHAS gracias! Era justo lo than amazed!

• Basis of LabVIEW Development with Compact RIO device software

  Hello.  Currently, I have the LabVIEW Base development software package and have been using it with DAQ Compact devices for the acquisition of basic data.  I would now like to start integrating controls in my system, changing to RIO Compact for deterministic real-time features.  My question is that I would be able to build applications for the Compact RIO system using only the basis of LabVIEW Development package without updating immediately?  Maybe some features are not available for me, but could at least get a good start like that?

  A CompactRIO embedded time real operating system (RTOS) called VxWorks you need to target the deployment of LabVIEW code to the device. Classic LabVIEW screws you will have been written so far are built to target general purpose operating systems (GPO) such as windows.

  To create screws that are deployable to STSOp, you will need the real-time Module that is not included in the basis of LabVIEW. As a result, to take advantage of the embedded FPGA, you'll need to install the LabVIEW FPGA Module as well.

  As long as you have the FPGA modules and in real time, it seems to me that you should be able to control these devices with LabVIEW Base. Without these software components you will not be able to create an instance of the device target your LabVIEW project.

• stand alone compact rio

  Hi to everyone!

  I am a student of the University and for my thesis, I use a COMPACT RIO with neither 9205 and gps module, some measures aboard an eletric car, measures will be saved to a TDMS file in the RIO COMPACT by a stand alone configuration and without connection to a pc.

  The compact rio will begins with the car and it will go off with him also.
  So I have a question, how can I stop the VI within the CRIO before turning off the car?  or in TDMS data will be saved in the same way without close the VI within the CRIO before turning off the car?

  Thank you

  Hello antoniolc!

  There is no way of knowing inside CompactRIO, if the system will be shut down.

  You must use an external signal to find out when your car will be stopped.

  Or you can use a multiple TDMS file and like it, just the last TDMS file will be unreadable. But you can probably read all previous TDMS files.

  Best regards.

• Reading Configuration files using Labview RT in a Compact RIO

  Hello

  I am very new to Labview RT/Compact RIO development platform and happen to have a question. I will develop an application in Labview RT / FPGA that will make several simulations. However some these simulations can produce different results depending on the configuration settings. Our systems generally run in a Windows application, were there is a configuration (usually in XML format) file that the application reads and analyzes the given parameters. I was wondering if there is something similar, that I can do it, in which I have a configuration file that can be read before my Labview RT/FPGA application initialization, to change the simulation.

  Thank you

  Mario

  Hi Mario,.

  That's right, there are screws for the files .ini on real-time targets.

• New user of Lab-view and Compact RIO

  Hi I am new to Labview environment and cRIO. I have to design a CAN bus for electronic car. I've done a few tutorials on how to create a VI. If anyone knows where I'll start to be able to send and receive messages using CAN bus and Compact RIO in order to implement the actual data from sensors or actuators CAN message?

  Thank you

  Abdoulaye

  Start with the examples provided with LabVIEW.  To the title of the help, select «Find examples...» ».  When the finder example opens select 'hardware input and output-> Compact RIO-> Module e/s specific-> CAN' and try to start with the basic example of CAN.

• Selection of Module e/s analog compact RIO

  Hi everyone, sorry if this is the wrong place to post, I couldn't see any analog IO section in the hardware section.

  I'm looking to acquire an analogue of module e/s for a compact RIO, but there are a few options, and I was wondering if there was any kind of guide to help me to choose the most appropriate module?

  Dawud,

  This will depend on especially what entries you want to read, but you must keep the following in mind.

  How much time do I need to purchase samples?

  Degree of accuracy these samples should be?

  How many channels do I need?

  What voltage range I have to read?

  You can start on the following link and choose the options on the left to get to the bottom for a few modules.

• Generation of data and acquisition of high frequency problem

  The fitting requires a fishing signal (32,764 KHz) saw tooth (0.3 Hz) signal output to drive the laser and acquires the signal from the output of the detector. I use the NI USB-6356 data acquisition with the speed limit of 1.25 MECH. / s.

  I put the generation mode like "Samples continues", samples of writing/reading of 1.2 M and 500K (Hz) frequency in the DAQ Assistant. I also tried 500K and 500K.

  The scheme of vi is illustrated in the following figure.

  

  Of the front plate, the generation of signal is normal, which may be seen in the left side of the following figure. But signals a lot of periodic fluctuations that will appear if the right side of the figure. In addition, the siganl acquist go all the time.

  

  I think it's maybe a few errors with my setting of the sampling frequency, I tried a lot of time for a change of pace, but it seems unnecessary.

  These fluctuations exist not only in the growing period but alos can be seen in the declining period, which is shown in the following figure:

  

  I tried to solve this problem for almost a week and try a lot of different rate, but all fail.

  Could someone give me any suggestions please? Thank you very much!!

  Thanks SOSOSO much for your reply immediately every time!

  This is my first time to write the Labview program with data acquisition

  I'll read the Web page that you offer, thank you very much once again!

• Compact rio

  Hello. I am a new user of Labview and I have a question for interfacing with FPGA. I have a 2 and a compactrio or 9237 which has a couple of pressure sensors connected to it. At the beginning I wanted to just make sure that my sensors work well so I tried to take their readings and comparing it with the calibration data. The problem is reading that I take does not change to alll according to the attached chart. Also, I have attached a few pictures of my program. I would appreciate if someone tell me what I'm doing wrong according to the attachments.

  Thank you.

  The way you wrote the code won't give you what you are looking for.

  • You run the FPGA code without delay, which means the FPGA with a frequency of 40 MHz clock runs the code much faster that your pressure sensor starting to respond.
  • You run the code just to acquire 20K samples that can be useful
  • Try running the code at all times with a delay of 100 micro seconds (10 kHz) and just use Code FPGA controls and indicators to read data in the RT/HOST.

• Frequency problem mouse Microsoft X 8 gaming

  I have three computers on a network in my basement and recently updated all three to the x 8 mouse. Two have Vista and XP. The problem I have is when playing fps the clicks of other X 8 mouse are playing games with them. My question is... Is it possible that all three can also be defined on different frequencies for don't mess does not with each other?

  Any help would be appreciated.

  Hi ddallas159,

  According to the Microsoft Hardware site, the Sidewinder x 8 is 2.4 Ghz, and there is no way to select a different frequency. You may need to replace it with a couple other mice for your application.

• Bug found during the use of references to the control in subVis on Compact RIO?

  Hallo,

  I have a simple task. I want to read higher VI into a Subvi the real value of a control to a level. I want to solve this problem by using a reference to the control.

  I have attached a simplified program that shows this.

  But the problem is now. When I run the main VI on a cRIO-device, the indicator "DataByReference" is not updated with the actual value. Only when I opened during execution of the "RefMain.vi" too, then everything works fine.

  More strange thing is, when I run the VI of hand on the host PC, everything works well, also without having to open the "RefMain.vi" when executing.

  Someone at - it an explanation for this behavior?

  Thanks in advance!

  Bernd

  This isn't a bug.  See this explanation.

• web control problem compact fieldpoint

  Hello

  I have a vi wrote to the PSC 2110.  It reads the values of a set of uf PSC-HAVE-110 of the blocks of analog input and writes the values to a cfp-do-401.  The program has two periods loops, to read and save the values to 6 hz and another to control three exits on the DO-401 to move a cylinder back and forth for a few tests of life cycle.

  When I run the program for the development on the PC it works fine, stops at the end of the cycle I set, etc.  When I build and set it to run when you start and connect to the PSC 2210 with a web browser, it also works very well and stops as it should as one remain in 'control' of it on the web browser.  However, when I start it up, then release control and just monitor, it will not stop as it should.  The user interface controls indicate that the ITO judgment, but the cycling continues to go and it keeps count.  Whenever I do a control of the application in the browser, it stops as it should.

  What is the difference between "control" and monitoring with regard to the delivery of the program?  I intend to leave this race without supervision and I really need to stop in time.

  Thanks for any info that could relate to this.

  Thank you

  What I did to solve this problem, is to create local variables of the controls I had to exploit by program and write to them.  Rather than use the node property Value.  It works fine now.
