Why do I get error "-1074388885" when using CANopen in PXI RT?

[al_ibr]

Dear all,

I built a test program (reading only the temprature of a motor) to use it later to exchange data between NI- PXI RT  and a LUST servo controller, which are locally connected with CAN network. Please see the attached VI. After run the program , a communication error with CAN network is happend. The error code is (-1074388885; CANopen NMT send.vi) after that the RT-Target give an error a message:
 
 (impossible to connect to target Real-time)
 
and then switched off. To connect it again, switched off/on of power supply has to be done.

I test the CAN connection between them with MAX, the test results give no problems.


Normally this test program was before running  correct between PC (with NI CAN-card) and Lust servo motor.

Does anybody have a solution?

Hi,

Could you provide the version of LabVIEW and MAX that you installed?
Which hardware do you use?

Hi Yann, Many thanks for your reply. The LV version is 8.6 and MAX is 4.5. The PXI RT has the following data: NI PXI chassis: 1031 NI PXI embedded controller: 8104NI PXI CAN card: 8461 The servo controller (Lust CDD3000) has a CAN card LUST CM CANI (see attached documentation). The equivalent program in PC with NI PCI CAN/2, which tests the data exchange with this servo controller, is attached (works without any problem). I attached the project file for the test program in PXI RT. Regards al_ibr

Hi,

Can you try test_progr_CAN_non_RT.vi directly on your PXI target. Just create a new LabVIEW project with your PXI target, add  test_progr_CAN_non_RT.vi under calculDroit target and launch the Vi.

Do you have an error?

Hello,

yes, I got the same error (begining by start remote node).

Can you provide a screenshot of all software that you installed on your PXI?(by using MAX)

Below you can find some KB related to CanOpen and RT Target:

Setup an NI-CAN Real-Time Application in MAX

Startup Application with CANopen VIs on Real Time Targets

Hope this helps.

Hello Yann,

Find below the schreenshot of PXI-Software.

I will let you know, if the Information provided in the link will help.

Hi Yann,

I tried with the provided information in the Links (included in your last reply). First I download the CAN chanells to the RT. Then I discovered that one file is missing (cvi_lvrt.dll) in the RT, as mentioned in the second link. It was difficult to put this file beside the existing one (ni_cano.dll) in the project tree, as described in the end of the second link.

I could only did a normal transfer through MAX using FTP_explorer (but I could not see it in the project tree).

After run the program, the same error is happend.
