• NOR-XNET CAN custom interface code in VeriStand

  Hello

  I work with NI Labview/VeriStand 2011 and I recently received a Council XNET/XS 8513 with my controller PXI - 8106 RT.

  I noticed a great NOR - XNET.dll (about 10 MB) download in the file system on the system deployment definition PXI. Therefore, there is a greater load on the processors during execution compared to the case when I used the jury CAN 84681. I think that the reason is the extension name to FlexRay and Lin (?) protocols.

  I'm trying to reduce the load, so I create a custom model of labview for the CAN communication only, XNET with message transmission. I tested it directly with LabView on PXI, without a VeriStand deployment; The result is a correct message, reading of the CAN bus.

  Then I try to do a project veristand, deactivation of the NOR-XNET interface on the system definition file and loading the labview simulation model (builds from /Tools/NI VeriStand/generate NI Veristand) model vi; but I can't read/write in real time any new value, despite a successful deployment.

  Is there some VeriStand dependencies that I forgot? How can I use the old source NI - XNET Device Custom code for this?

  Thank you

  Giulio

  OK, I solved the problem: inport VeriStand cannot be a digital control of LabView inside a while loop time.

  Now the application is running well.

• Properties of the NOR-XNET CAN frame timing type

  Hi all

  I have a problem of timing of the CAN. I start to read / write CAN bus every 10ms. I am using loops timed for this and I usually see 9ms / 10ms loop intervals of itteration, that's fine. However, sometimes my comms CAN down completely and that the loop can take 5 seconds to turns off once. The work rate of the cpu (from the Task Manager) does not seem too badly loaded)<>

  I noticed in the editor of database of NOR-XNET, I have the choice of the type of calendar. I am currently using the event data, but I was wondering if there was something I could do to use some kind of hardware timing for my transmissions CAN? Curiously, neither aid seems fairly limited for the calendar type (where my post here). Any help on what means the type of calendar options, and if a is likely to strengthen my time 10ms loop and (hopefully) stop my bus CAN lock up risks would be apprciated.

  Thank you very much.

  I use 'Framework in single point' for my readings and 'Unique exit point' for my writing.

  I chose the type of cyclic calendar with a time limit for the transmission of 10ms in my NOR-XNET database. It seems to be better now, - I haven't seen 1 instance of my may lock up repeatedly. I still have my loop timed to 10ms containing my NOR-XNET write VI.

  I'm not using a queued session, - if I understand correctly, the queue will hold managers and they will be released sequentially at intervals of 10 ms? The only point & cyclic timing so I understand that if a new image is written so the same frame will be published every 10ms. - it fits my needs for now.

  After reading the help, point one looks like it will work enough for you.  Keep in mind that if you finish writing twice before the next transmission 10 ms, you can miss an update signal.  This can happen if your software update of 10ms is not quite of the transmission of material 10 ms.

  With the type of cyclic calendar and Frame in single point, are my transmissions CAN timed material now? -They seem more regularly now and I have not had a case of the loop CAN lock up.

  The cyclical schedule will force the transmissions timed HW of the controller CAN then Yes, you're now HW timed for transmission.

  Thanks again for your help.

  I'm glad that your CAN bus seems to be much happier now.  Feel free to post if you have something else.

• NOR-XNET and CAN - FD

  Hello

  The OR Web site mentioned the XNET interfaces are compatible CAN - FD. Could you tell me which are the XNET interfaces with FD CAN 11898 - standard 2:2015?

  Kind regards

  Hello SmileBoB,

  Supported devices:

  In general, the family of NOR-XNET CAN interfaces of is designed to be high performance modules that are easily adaptable to new standards and protocols. Since the physical layer CAN FD is very similar to that of high-throughput CAN, all interfaces CAN of NOR-XNET that support high-speed CAN communication also support FD CAN with bit rates up to 8 Mbit/s.

  The list of NOR-XNET interfaces that support communication CAN FD is below:

  PXI

  
  
  • OR PXI-8513/2
  
  
  • OR PXI-8513
  
  
  • OR PXI-8512/2
  
  
  • OR PXI-8512
  
  

  PCI

  
  
  • OR PCI-8513/2
  
  
  • OR PCI-8513
  
  
  • OR PCI-8512/2
  
  
  • OR PCI-8512

• NOR-XNET Bus Monitor does not detect port

  Hi all

  I need somehelp. I have 2 PXI-8512 and assembla CAN1 CAN2, CAN3 and MAY 4.
  I want to control my XNET data traffic. Yes, they are available in MAX. But once I open the monitor of Bus OR-XNET, every channel I have are not detected.  Interface name box is empty, does not show anything.

  Here is a screenshot.

  

  Someone knows what's the problem?

  Thanks for help.

  Rajamodol

  Hey Rajamodol, Nicola.

  I'm sorry, but this is a limitation of the distant targets in XNET bus monitor. See the following Knowledge Base article:

  Why can I not see my NOR-XNET CAN interface on my remote target in Bus monitor? -National Instruments
  http://digital.NI.com/public.nsf/allkb/92F10284E8061FB68625793600484D79?OpenDocument

  The article also mentions an alternative, where you use an example VI for a similar feature.

• detect single-point XNET CAN timeout

  Hello

  I've implemented a CAN communication via Signal XNET single-point settings.

  I need to detect a time on the CAN line if a bus-elect is no longer active. I found this possibility for the parameters of FRAME CAN, but not single-point signal.

  How can I implement this timeout notification?

  Thank you very much

  Magnus

  Hello Magnus,

  first that I want to recommend the "single-point input Signal Mode" in the XNET help (first link in the XNET (single-point Signal) reading .vi) article for a better understanding of the feature.

  If you wish to set up an audit of the time-out period, you can use the function "XNET .vi (XY Signal) read", so that you get a delivery timestamp. When query you that you can build a lag.

  Best regards

• Filtration of single-point data

  Hello, I'm trying to filter the data of voltage point unique task, but there is an error of frequency... I have set at 120 Hz sampling frequency and I want bandpass filter for example of 30 to 40 Hz...

  

  So, where is problem? I tried to use a timed loop or "align and re - sample" sampling frequency, but this filter still does not work...

  

  You know, how to use this filter with single point task? When I do my own filter FIR with the same settings, the results are not same, this is the reason why I want to use this filter.

  If I use DAQ Assistant, there is no errors, but I can't use for other reasons (1) I can't use single point and all daq assistant, daq assistant 2) can't do pressure)

  

  These images add nothing to the discussion. If you buy a single point at a time, you have NO frequency and cannot use the normal filter function. Do what I said or use multi-sample reading or single reading point and build the table before making a filter. Best is to use the acquisition of data with several samples.

• NOR-XNET - invalid CAN interface

  Hello

  Main problem:

  I have problem to get CAN interface in my PXI rack up to-and-operational. The interface name is not valid

  Material:

  SMU-1078, with SMU-8820 and CAN controller module NI PXI 8512

  Software:

  LabVIEW 2015

  Driver OR XNET 15.5 (both portable and PXI)

  Description of the problem:

  When we look in MAX, OR XNET interface says I have two interfaces CAN named 'CAN1' and 'CAN2.

  It is also possible to use the funtion "blink port" successfully, CAN1 and CAN2.

  BUT, when you use the bus monitor feature, I got error saying that "given the Interface name does not specify a valid interface and existign"

  See pictures attached below.

  Also, when you try to use the code example, CAN Test.vi of closure, the same error occurs.

  Someone knows how to fix this?

  Hello
  Thanks for the support.
  I found the problem
  When you use MAX first, to set up a session n xnet, MAX does close properly the session.
  So, when using the BOX of the labviewcode channel, will result in this error code.
  No, an explanation of very good code, but I would say.
  It is perhaps difficult for labview to know if the channel is busy or does not exist.

• NI-CAN for NOR-XNET delphi application migration

  I want to migrate a NI-CAN for NOR-XNET application. My application running on a NOR-PCI-CAN Series 2 and I need work on an NI PXI-8512.

  I develop with delphi.
  I followed the tutorial 'NI-CAN NOR-XNET Applications migration': http://www.ni.com/white-paper/9717/en/
  I can see the map to the MAX as explain in the tutorial.

  I realized a small application that displays the data. This application works well with my first card, but did not work with the new.

  It draws in the NI-CAN, I use: ncConfig, ncWaitForState, ncOpenObject and ncRead.

  I want that my request of NI-CAN work on my new card without touching the source code. Is this possible?

  This tutorial is only for LabVIEW. I think you need to edit your source to use the new card.

• What are the causes of error - OR-XNET: the NOR-XNET driver is no longer can communicate with the device.

  Hello

  I use X-NET-PCI8512, OS: Windows 7, C++ (middle of the QT interval).

  I'm pooling of card data (StreamIn member function) to ~ 100 Hz. card reading time (ReadStatus) to ~ 100 Hz.

  After about 40 min (depends on the amount of data in) I get this error:

  (Hex 0xBFF630B2) The NOR-XNET driver cannot communicate with the device. Solution: Make sure that the device was not removed from the computer.

  What are the causes of this error?

  Thanks in advance,

  Aviad

  Hello aviadCielo,

  When you get this error, what does do to make it work again? If you restart your program, start all this work?

  Secondly, what version of NOR-XNET do you use? It's maybe a software problem that could be resolved by upgrading to NOR-XNET 1.6.

  Finally, can you reproduce this problem with a simple program? If so, you can join the program you use?

• When I clik on a link to view another Web page or another document, a blank page appears (a single "point of png'). How can I solve this issue?

  The links are located on the emails I receive from authorized sources. When I click on the links to read the additional documents (another document) or display a picture, I get a blank page with a single point in the middle of the page. The tab header says it's an image (1 x 1 pixel) PNG. Any suggestions to fix this?

  Often, links to email in bulk are routed via a follow-up rather than service directly to its final destination. If you look at the address bar on the image page, it seems like one of these intermediaries rather than the page you expect to load? If you click on the address bar and press ENTER to retry the address, which does nothing?

  It is possible that the security software or security add-on kills a redirect from this intermediate page to the final destination. For example, I think the anti-banner Kaspersky functionality could do that.

• Is it possible to save a configuration with NOR-XNET Bus Monitor?

  I'm trying to transition to use Vector canoe to use NOR-XNET Bus monitor.

  In Bus monitor is it possible to save the settings of the interface and the signals tab setting?

  Do not think that as Bus monitor, it's more like a low level tool to see if things work.  Very little effort seems to have entered the user experience or user interface.  OR prefer generally to develop tools, which you can use to request a wonderful, they generally don't do this wonderful application themselves.

  I would look at a few examples in LabVIEW, by going to help > find examples to see if any of these get close to the functionality you're looking for.  Then you can use as a starting point for your own application.

• Single-point PXI 8106 timed performance material

  Hello

  I'm potentially interested in buying a PXI-8106 module for my application of servo motor control. I would like to know that single-point timed material loop rate performance of this command when used with DAQmx, before buy you. Does anyone have statistics of performance for this controller to the benchmarks of NOR (http://www.ni.com/white-paper/5423/en/)? Ideally, I'd be able to get execution rate of loop for T1 to T4 tests, for 1 and four lanes. I can't find this info online.

  I am currently borrow a PXI-8108 for my setup and I can reach nearly twice my goal of 2 kHz loop rates. I also know the performance of the 8108RT to the above reference, so if I had the same numbers for the 8106 I should be able to judge how the 8106 happen for my application.

  Thank you

  Jason

  Hello

  We do not have these data posted, but looking at the specifications for these two cards, I imagine that you would see no more than a 20% drop in performance between the two.  Probably less.

• Unable to deploy the NOR-XNET database on target RT

  Currently, I am expierencing trouble with NOR-XNET databases on an RT target deployment.

  When I check my alias on my local computer, all right. The problem is the target, it is stuck on the alias used previously, and I can't add new ones.

  When I open "Manage aliases" database editor and enter the target IP, the program crashes. Same thing with LabView; When I click on "Manage the deployment of the database" in the drop-down list where I choose LabView crashes database files. When I simply click 'Browse for database file', nothing happens. With the databases that are currently in memory, I get a dropdown list out all signals in this database.

  Who knows what could cause the link broken between my computer and the target, it is impossible to deploy new database?

  I'm using Labview 2010 SP1 with NOR-XNET 1.5, and I've attached all drivers installed on the target.

  Thierry,

  Disabling the firewall did the trick! I could update all the databases on the target, and the two problems have disappeared.

  So, if you can't deploy a NOR-XNET database, disable the windows firewall!
