Issue Details

I use a cRIO 9039 in an hybrid mode with a 9881 CANopen module. I get an error when I launch the project:

Error -2147137023 occurred at CANopen Emergency Create.vi:6970001 

Why does this error occur? What can I do to avoid it?

Solution

Because you are working in an hybrid mode, you have to run the FPGA bitfile at the beginning of your code and not close it until the end. During the execution of your program, you must not close or reset it. If you encounter this error, you probably close or reset the FPGA somewhere in your code. To avoid this error, you must open your reference and leave it open until the end of your code.
