FUE950 M_bus通讯调试

FUE950 M_bus通讯调试

一、通讯数据格式

波特率：300bps或2400bps

数据位：8位

停止位：1位

校验：偶校验EVEN

二、物理连接

M_bus转换器485端：

485A端接485网络A+，485A端接485网络B-。

M_bus转换器M_bus端：

FUE950的M_bus通讯卡两个端子，一端接M_bus+，另一端接M_bus-，反接无影响。

M_bus转换器接24V直流输入，即可工作。

三、标准通讯数据

发送（16进制）：10 5B 18 73 16

接受范例（16进制）：

68 6C 6C 68 08 18 72 24 93 47 47 25 4D 52 0C 78 50 00 00 0C FB 00 00 00 00 00 8C 10 FB 00 00 00 00 00 8C 20 15 00 00 00 00 0C 15 00 00 00 00 3C 2D BD EB DD DD 0B 3D 00 00 00 3A 5A BD EB 3A 5E BD EB 3A 62 BD EB 0A 27 00 00 04 6D 2E 10 BC 1B 4C FB 00 00 00 00 00 4C 15 00 00 00 00 CC 10 FB 00 00 00 00 00 CC 20 15 00 00 00 00 42 6C BF 15 7B 16

数据剖析：

得到的数据有：总能量、累计流量、瞬时流量、当前操作天数和当前时间。

0C FB 00 00 00 00 00，查表可知能量单位0.1MWh的代码是FB 00，所以得到的能量值是0.0 MWh

0C 15 00 00 00 00，查表可知累计流量的单位是0.1m^3的代码是15，所以得到的累计流量是0.0 m^3

0B 3D 00 00 00，查表可知瞬时流量的单位是0.1m^3/h的代码是3D，所以得到的瞬时流量是0.0 m^3/h

0A 27 00 00，查表可知当前操作天数的代码是27，所以当前操作天数是0天

04 6D 2E 10，查表可知当前时间的代码是6D，所以当前时间是10:46
