Description

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.

Note 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).
