Hi,

There isn't any API call to flush the CAN queue.

You can use ncReset to put the CAN board on its power on state. The function actually reloads the board's firmware, so it resets the board just as if it was powered on.

Check the following knowledge base article:
Using the "ncReset" function with NI-CAN

HI,

The  knowledge base article is not available !!!

The KB is no longer available , because we do not recommend to use the ncreset anymore. Instead use the ncaction with reset option to flush the buffers.

For a power on and off, you need to reset the board from MAX. (CTRL+ SHIFT and right mouse click to the board).

Is there a way to do this with the Channel API and the associated VI's?  If not, can the ncaction be used along with the Channel VI's?  I need a way of shutting down any tasks which are running.

Hi,

unfortunately there is no reset option available for the channel api. But normaly the task clear function should clear the buffer too.
