4)CAN具有的完善的通信協(xié)議可由CAN控制器芯片及其接口芯片來實現(xiàn)，從而大大降低了用戶系統(tǒng)開發(fā)的難度，縮短了開發(fā)周期，這些是僅電氣協(xié)議的RS-485所無法比擬的。

5)與其它現(xiàn)場總線比較而言，CAN總線通信速率可達1MBPS，傳輸速率為5KBPS時，采用雙絞線，傳輸距離可達10KM，并且數(shù)據(jù)傳輸可靠性高;CAN總線是具有通信速率高、容易實現(xiàn)、且性價比高等諸多特點的一種已形成際標準的現(xiàn)場總線。這些也是目前 CAN總線應(yīng)用于眾多領(lǐng)域，具有強勁的市場競爭力的重要原因。
