Owning Palette: CANopen VIs
Sends a remote transmission request (RTR) to a transmit-process data object (TPDO) producer. When the TPDO producer receives the RTR, the producer sends out a PDO to the CANopen network. The COB-ID of the TPDO corresponds to the COB-ID in TPDO object in.
This VI is optimized for real-time performance. This VI executes with low cost and avoids access to shared resources that can induce jitter.
