Data frame
Remote frame
Error frame
Overload frame
The following four types of frames are used in the CAN protocol.
(1) Bus value
(1) Data frame
The bus values are divided into dominant and recessive.
• Dominant level is indicated by logical 0.
• Recessive level is indicated by logical 1.
• When a dominant level and a recessive level are transmitted simultaneously, the bus value becomes dominant
A data frame is composed of seven fields.
