Modbus连接器配置(tb-gateway)

tb_gateway.yaml简单介绍

• Thingsboard–连接到ThingsBoard平台的配置。
  • security–加密和授权类型的配置。

storage–存储方式配置（内存或文件）。

• connectors–连接器列表及其配置。

  tb_gateway.yaml配置

  在tb_gateway.yaml中打开Modbus Connector

  thingsboard:
  host: demo.thingsboard.io
  port: 1883
  security:
    accessToken: PUT_YOUR_ACCESS_TOKEN_HERE
  storage:
  type: memory
  read_records_count: 100
  max_records_count: 100000
  connectors:
  -
    name: Modbus Connector
    type: modbus
    configuration: modbus.json

  modbus.json介绍和配置

  官网介绍
  注释中modbus相关的解释

• thignsboard支持的modbus功能码（1/2/3/4可作为属性/遥测的functionCode且2/4是只读，5/6/15/16作为rpc的functionCode）

  • 读数据
    • 1 读线圈 读写
    • 2 读离散输入 只读
    • 3 读多个保存寄存器 读写
    • 4 读保持寄存器 只读
  • 写数据
    • 5 写单个线圈
    • 6 写单个寄存器
    • 15 写多个线圈
    • 16 写多个寄存器
