XNET Wait (CAN Remote Wakeup) (G Dataflow)

Last Modified: February 22, 2017

Waits for the CAN interface to wake up due to activity by a remote ECU on the network.


session in

The session to apply the wait.



An input that specifies the maximum amount of time in seconds to wait.


error in

Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

Default: No error


session out

An output that is the same as session in, provided for use with subsequent nodes.


error out

Error information. The node produces this output according to standard error behavior.


This wait is used when you set the XNET Session Interface:CAN:Transceiver State property to Sleep. When asleep, the interface and transceiver go into a low-powered mode. If a remote CAN ECU transmits a frame, the transceiver detects this transmission, and both the controller and transceiver wake up. This wait detects that remote wakeup.


The interface neither receives nor acknowledges the transmission that caused the wakeup. However, after the interface wakes up, the transceiver automatically is placed into normal mode, and communication is restored.

The timeout parameter provides the maximum number of seconds to wait. This value must be 1.0 (one second) or greater. The default value is 10 (10 seconds).

Where This Node Can Run:

Desktop OS: Windows

FPGA: Supported
