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.vi
Possible 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. -
Well, the "Possible reason(s)" seems fairly self-explanatory. Were you trying to change the baud rate while your project was running? The message is telling you not to do that. You need to configure the settings before connecting to the module.
You cannot set a property while the task is running. If you need to change a property prior to starting the task, you cannot use CAN Init Start.vi. First, call CAN Initialize.vi, followed by CAN Set Property.vi and then CAN Start.vi. After you start the task, you also can change a property by calling CAN Stop.vi, followed by CAN Set Property.vi, and then CAN Start.vi again.
I only use the CANopen Library. I found the mistake. I only closed the CANopen-object but not the CANopen-interface! You can see the solution in the pic.
