Determines whether the CAN interface retries failed transmissions.


You can modify this property only when the interface is stopped.

Data type: datatype_icon

Long Name: Interface:CAN:Single Shot Transmit?

Class: XNET Session

Permissions: Read/Write


Setting this property causes the internal queue to be flushed. If you start a session, queue frames, and then stop the session and change this mode, some frames may be lost. Set this property to the desired value once; do not frequently change modes.

When this property is FALSE, failed transmissions retry as specified by the CAN protocol (ISO 11898–1, 6.11 Automatic Retransmission). If a CAN frame is not transmitted successfully, the interface attempts to retransmit the frame as soon as the bus is idle again. This retransmit process continues until the frame is successfully transmitted.

When this property is TRUE, failed transmissions do not retry. If a CAN frame is not transmitted successfully, no further transmissions are attempted.

Web Server: Not supported in VIs that run in a web application
