市面上正泰无论是ddsu 单相表还是dtsu三相表485出厂协议有两种DL/T645-2007 和modbus rtu 三相带通讯价格在200左右，modbus好像会贵个十几 二十块钱，单相强烈建议购买出厂协议为modbus的。因为新款单相的虽然有按键了，但只有一个按键，不能修改只能查看。 三相的有三个按键 可以通过按键菜单修改协议和其他参数。
1. type可以填tcp 和rtuovertcp ，如果网关转换就填tcp ，否则就由ha 转换填rtuovertcp
2.网关每个端口智能一个客户端连接，否则数据会错乱，要多个连接，就要新建一个端口
3.address 可以填十进制也可以填16进制 ，16进制以0x开头，直接抄说明书地址即可不用转换，更方便。
4.当显示数字很大很小的时候可以调整 scale 如：0. 01 0.1 1000等
5.slave 为电表地址，串接多个设备时需要调整设备地址
6.precision 为小数点精度
7. data_type 为float32 , float16我试了不行
8. state_class: total device_class: energy 如果要在能源中使用 请设置这两个参数
9，网关的波特率，位数，停止位，必须和电表一致。
