The Pending Transmit Order property configures how the CAN interface manages the internal queue of frames. More than one frame may desire to transmit at the same time. NI-XNET stores the frames in an internal queue and transmits them onto the CAN bus when the bus is idle. This property modifies how NI-XNET handles this queue of frames. The following table lists the accepted values: - As Submitted - By Identifier When you configure this property to be As Submitted, frames are transmitted in the order that they were submitted into the queue. There is no reordering of any frames, and a higher priority frame may be delayed due to the transmission or retransmission of a previously submitted frame. However, this mode has the highest performance. When you configure this property to be By Identifier, frames with the highest priority identifier (lower CAN ID value) transmit first.
