Modbus is a data communications protocol originally published by Modicon (now Schneider Electric) in 1979 for use with its programmable logic controllers (PLCs). Modbus has become a de facto standard communication protocol and is now a commonly available means of connecting industrial electronic devices.

Modbus是一种串行通信协议，是Modicon公司（现在的施耐德电气 Schneider Electric）于1979年为使用可编程逻辑控制器（PLC）通信而发表。Modbus已经成为工业领域通信协议事实上的业界标准，并且现在是工业电子设备之间常用的连接方式。

RS-485, also known as TIA-485(-A) or EIA-485, is a standard defining the electrical characteristics of drivers and receivers for use in serial communications systems. Electrical signaling is balanced, and multipoint systems are supported.

EIA-485（过去叫做RS-485或者RS485[1]）是隶属于OSI模型物理层的电气特性规定为2线、半双工、平衡传输线多点通信的标准。

# 主要的配置文件就这几行
# host 设置为上面提到的模块的管理地址
# type 就是上面踩坑的协议 建议设置为这个 兼容性更高
# port 也是上面配置的模块的端口
- name: hanfeng-pe11
  type: rtuovertcp
  host: x.x.x.x
  port: 502

  # 关于模块的配置 主要就是配置一个上面设置的地址
  # 以及配置寄存器的地址

  # 根据说明书 正确填写寄存器地址
  # 寄存器长度
  # 数据类型
  # 这里要提到的一点是，上面踩的数据转换的坑 不需要单独配置就可以正常显示
