baud rate

[can can canopen]

Hi All,
 
I am working on CANOpen protocol, In one of the application I have to change the baud rate twice.
The whole application is like this , I have a Motor control drive, the initial baud rate of the drive is 250, CANOpen is used for communication .
 
I can change the baud rate once and can check communication in drive by accessing some of the parameters, after this I again changed the baud rate to some other value and when i try to check the communication , I am getting CAN Interface create error.
 
This is the problem i am facing.

Hi,
Are you changing the baud rate on a fly or stopping the program, changing the baud rate and then running it back again?
Thanks,

No I am not stopping the program.
I had checked in that direction too, change baudrate save that,switch off and switch on drive,check communication .That program works .
But not this type of program.

Hi,
 

I have a CANopen-IO-Module which I want to test, I want to change the baudrate and check communication.I use a NI-PCI-CAN-Card and LabVIEW with the CANopen-Library for communication.


  
After I changed the baudrate of the IO-Module, LabVIEW stops and shows the following error:- Error -1074388985 occurred at CANopen Interface Create.viPossible reason(s):NI-CAN:  (Hex 0xBFF62007) You attempted to set a configuration attribute while the object is running.  Solutions: Configure attributes prior to opening the object; Stop and restart communication as needed so that you can update configuration attributes.- wants wrong??
