Description: 串行口RS485自定义通讯协议，2、功能定义
（1） 监视从机运行状态
（2） 控制从机运行
（3） 读取从机功能码参数
（4） 设置从机功能码参数
3、通信协议方式
PC，PLC 为主机，变频器为从机。采用主机“轮询” , 从机“应答”的点对点的通信方式。轮询可以建立在一个轮询表内，如果是广播发送变频器不用应答。用户可以利用变频器键盘设置变频器的本机地址（默认为00H）。-Custom RS485 serial port communication protocols, 2, function definitions (1) watch from the machine run state (2) control from the machine running (3) reads parameters from machine function code (4) set the parameters from the machine function code 3, communication agreement PC, PLC as the host, converter from the machine. With host " polling" from machine " response" of the point to point communication. Polling in a polling table can be established, if no response is broadcast to send inverter. Users can use the keyboard to set the inverter frequency converter local address (default is 00H).

Description: RS485协议，在工业控制等环境中，常会有电气噪声干扰传输线路，使用RS-232 通讯时经常
因外界的电气干扰而导致信号传输错误；另外，RS-232 通讯的最大传输距离在不增加缓冲
器的情况下只可以达到15 米。为了解决上述问题，RS-485/422 通讯方式就应运而生了。-RS485 protocol, in the industrial control environment, often have a transmission line of electrical noise interference, the use of RS-232 communication often
