LAN System - Mechanism & Function: General: Can

CAN is a serial communications protocol in compliance with relevant ISO standards.
With its high bit rates, CAN enables quick, large-volume data transmission/reception.
Based on continuous change in bus level (logical signals: low "0" and high "1") stemming from voltage difference between CAN_High and CAN_Low, data and other frames are configured for message identification.
If an error is detected, CAN's fault confinement feature prevents the error from impacting units.
If an error is detected, an error frame (notification that an error has been detected) is sent to units, telling them not to perform control based on data including errors.
Depending on the status of the error detected, transmission/reception of the relevant data will be aborted.
