CANopen Error

[R_J]

Hello

In my application i am communicating to a device using CANopen protocols. I am using High speed PCMCIA CAN card , Labview 8.0 & NI CANopen Labview library.

In my system NI CAN 2.3.2 is installed.

Sometimes  i am getting error

         

Error code: -1074388990

Description: An internal error occurred in the NI-CAN driver. A description is located in the file Nican Err.txt in your windows folder.

Solutions: Email or fax the NicanErr.txt file to NI for Technical support

After getting this error first time i had reinstall the CANopen library functions. But after that i again got the error.

Please find the attached error code.

 Please reply as soon as possible. It is very urgent.

Regards ,

Hi,

This error means there is something going wrong with the initialization for your CAN board. Thats something between the driver and the board.

Try to install the newest NI CAN 2.3.3 version, which you can find here: NI-CAN 2.3.3

Hi Dirk

Thank you very much for your reply.

But i am not able to download the NI CAN 2.3.3 .exe .

Every time   i am getting an error stating that

             The server returned an invalid or unrecognized response.

Please reply as soon as possible.

i have to deliver the project after two days.

I need one more help releated to creating an installer.

I am using LV 8.0 . NI CAN 2.3.2 , NI CANopen Labview library functions , NI USB 8451 card.

I am getting an error while creating the installer.

I had tried this on four different PC . For the first time i am able to create the installer successfully but if i tried to create the installer again then some error occurs. Find the attached errors.

Please reply as soon as possible

Thanking You

Hi,

I could not reproduce the download problem. Perhaps your security configuration does not allow to download a selfextracting executeable?

To the second problem: It seems the installer builder can not find a specific file or component. In your case something from the RT Error dialog.

Follow the path to find what is missing.

Hi,

I would like to use the USB-8472 interface and NI CANopen library. Is possible tu use this combination?

Thank you,

Pavel

Hi,

unfortunately not. The CANopen Library uses Frame API Objects under the hood and USB CAN does not support these objects.

The only portable solution for the CANopen Library is PCMCIA.

Is there any plan to bring CANopen to the USB-CAN devices in the near future?

Because it is hard to explain to management, that we have to order parts which are more than twice expensive than the USB-CAN (~900EUR for the PCI and only ~320EUR for the USB)

[DirkW]

Well, thats the reason why the USB CAN device is cheaper, then the Plug-In boards. It has no cpu and therefore it can not handle hardware timed transmit, which is essentially for CANopen for example. In the future we will certainly release "better" USB products, with build in CANopen support. But the price will go up to the same range, you can buy the plug-in boards now.

that is what I expected to hear.

Beside the price the flexibility of the USB is the interesting part for our company because we have a mixture of laptop/desktop computers as base of our measurement hardware. Most of the time right the needed CAN-Card (PCMCIA or PCI) is not available 🙂

Do you perhaps have a rough time schedule for the "better" USB devices?
