Key Features of SAE J1939

Standardization: It allows for standardization across different manufacturers, making it easier for components from different suppliers to work together seamlessly.
Network Management: SAE J1939 uses a single-master, multi-slave, peer-to-peer network structure.
Message Structure: Messages are prioritized based on their urgency and have specific formats for parameters like data page, message type, and PGN (Parameter Group Number).
Addressing: Devices on a J1939 network are identified by an address, which must be unique to each node.
