Fusheng SC Series Controller Modbus Protocol Address Table and Description缩略图

The RS485 port of the Fusheng SC series controller complies with the ModBus RTU protocol, and its communication format is fixed as "9600 E 8 1". Its meaning is:

-  波特率: 9600 bps

-  检验位:偶校验

-  数据位: 8 位

-  停止位: 1 位

注:复盛某些控制器的波特率是可调整的。为了避免出错,强烈建议采用默 认设置值: 9600bps

复盛 SC 系列控制器仅支持 ModBUS RTU 的 3 号和 6 号功能码,其通讯格式 如下:

3 号功能码: 读 N 个字节

主机请求:

从机地址功能码初始地址数据长度CRC 检验码

从机响应:

从机地址功能码数据长度数据内容CRC 校验码

6 号功能码: 写 1 个字节

主机请求:

从机地址功能码寄存器地址设置数值CRC 校验码

从机响应:

从机地址功能码寄存器地址设置数值CRC 校验码

注: 1.   “远程启动”和“远程停机”、“强制加载”和“强制卸载”分别是互锁的, 一个指 令置“1”时,另一个必须清零。

2.  要使“远程启动”或“远程停机”指令有效,先置“1”,2~3 秒后清零即可。
