The difference between CAN bus and 485 bus

The difference between CAN bus and 485 bus:

1. Communication method: CAN adopts multi node communication, and 485 uses a single node to control multiple slave nodes;

2. Communication speed, CAN data transmission speed is higher than 485;

3. Distance limit, CAN communication distance between 40-500 meters, 485 can reach 1200 meters;

4. Data transmission reliability, CAN has higher data transmission reliability than 485;

5. CAN adopts a decentralized network structure, while 485 adopts a star topology structure;

6. The cost of CAN equipment and wiring is higher than that of 485.
