由于CAN不仅便宜,而且其各种功能(例如优先考虑帧报文的重要性并适当处理关键信息)使其比RS-485具有更加显著的优势。CAN总线在更大范围内大大简化了开发和故障排除过程,目前,实施 CAN的成本远低于实施RS-485。 引用: https://www.moxa.com.cn/getmedia/a07808dd-f3d7-473b-9a2f-93b5ce673bb1/moxa-the-secre...
不同于RS485,没有终端电阻的时候也能工作,只是会导致高频信号反射,最终让波形难看一点,眼图闭合一些。 485是H桥驱动,0和1都是强驱动 如果CAN不加终端电阻,那么他会在recessive status放不了电,导致报文错误 CAN是开漏输出形式,0是强信号,是显性的;1是弱信号,是被动地在终端电阻上放电才行的。 properly terminati...

串口通信是指采用串行通信协议(serial communication)在一条信号线上将数据一个比特一个比特地逐位进行传输的通信模式。 串口按电气标准及协议来划分,包括RS-232-C、RS-422、RS485等。 1.串行通信 在串行通信中,数据在1位宽的单条线路上进行传输,一个字节的数据要分为8次,由低位到... ...
近日,川土微电子CA-IF1042VS-Q1 CAN收发器顺利通过德国C&S实验室兼容性认证。 德国C&S即Communication & Systems Group实验室简称,是行业内公认的测试车载芯片能否实现互联互通和网络兼容的行业标杆性权威认证机构。由于智能网联汽车对网络中组件的协同性要求非常高,而协同性直接关系到组件的互操作性程度,C&S测试正是为...
Modbus enables communication through serial lines such as RS232 or RS485, as well as Ethernet, making it suitable for diverse communication environments and devices.However, Modbus's principal constraints are its relatively lower efficiency and lack of real-time capabilities. As a master-slave ...
