6FX1111-0AG02 1、国际标准的工业级现场总线，传输可靠，实时性高；

2、传输距离远（最远10Km），传输速率快（1MHz bps）；

3、节点数量最多可达110个。

4、采用短帧结构，每一帧的有效字节数为8个；

5、实时性高，非破坏总线仲裁技术，优先级高的节点无延时；

6、出错的CAN节点会自动关闭并切断和总线的联系，不影响总线的通讯；

7、报文为短帧结构并有硬件CRC校验，受干扰概率小，数据出错率极低；

8、通讯介质可用普通的双绞线，同轴电缆或光纤等；

9、可以点对点，一点对多点及全局广播几种传送方式接收数据。

RS485接口标准特点：

（1） RS-485的电气特性：逻辑“1”以两线间的电压差为+（2-6）V表示；逻辑“0”以两线间的电压差为-（2-6）V表示。接口信号电平比RS-232-C降低了，就不易损坏接口电路的芯片，且该电平与TTL电平兼容，可方便与TTL 电路连接。

（2） RS-485的数据传输速率为10Mbps

（3） RS-485接口是采用平衡驱动器和差分接收器的组合，抗共模干能力增强，即抗噪声干扰性好。

（4） 因RS-485接口具有良好的抗噪声干扰性，长的传输距离和多站能力等上述优点就使其成为的串行接口。

区别：

1、速度与距离

2、错误检测机制

3、价格与培训成本

4、总线利用率
