有没有可能不适用于高速通信，485我们只用9600甚至更低，因为启停控制是接线连接，485只是传输数据没必要反应那么快，加上还要轮询，天生就不适合干高速控制的活，要速度快就上Ethercat、cclink、profibus/profinet

谢谢，学习了]]></description>

 <description><![CDATA[与汇川变频器通讯一直用 57600&#160;&#160;都没啥问题&#160;&#160;&#160;&#160;
唯一碰到一个客户 工作接零与保护接零混着用 旁边还有压铸炉&#160;&#160;&#160;&#160; 某雷雨天通讯卡坏了好几片
靠变频器起家&nbsp;&nbsp;国产工控一哥&nbsp;&nbsp;不可能这么弱&nbsp;&nbsp;]]></description>
