Resetting CAN bus without knowing task reference

Question

Good morning everyone,
I am using the CAN Channel API to read data coming in from a CAN bus while simultaneously taking measurements using other DAQ hardware. When my VI throws an error after the CAN bus has been initialized and started, attempting to run my VI again will cause the CAN init-start VI to throw an error because the channel was never cleared.
Is there a way to clear a CAN channel without having a task reference to wire? How else could I solve this issue?
Thanks!
Erik

Hi Erik,
Is the error that you're experiencing coming from the same function on a regular basis?  If so, what can be done prior to adding error handling to the entire application, you can add a case structure, use the error cluster from that function to act as the selector for the case structure, and add a Clear Channel command to the true case of the structure followed by an error handler.  
Now, that said, I still recommend employing error handling throughout the application, especially if this will be distributed as an executable.  But for development purposes, that may be the quickest way to implement a Clear function on failure in the VI so that it will restart correctly on the next iteration.
