CANopen “autoreply” at the level of CAN interface Series 2

CANopen “autoreply” at the level of CAN interface Series 2

‎11-12-2010 04:06 AM

An external device sends the same frame on a regular base (sync frame). The program must reply to each such a frame sending back an information-containing frame. The reply is always the same (until some changes eventually occur but the changes are out of this question). The process is quite fast and loads the processor too much.

 

I got an advice that can be summarised as following:

* This “autoreply” process can be moved to the CAN card unloading the main processor.

* Series 2 cards are suitable for such a work (now I have PCMCIA-CAN/2).

* CANopen library has to be used to implement the idea.

 

Unfortunately, I have no experience with CANopen/CANopen LabVIEW library. The attempts to get started with help of the manual and examples were not successful.Smiley Sad

 

Please give me a hint how to approach this problem. Which features of the CANopen library allows setting such task to the CAN card?

 

Thank you
