EG2000+ET2100组网-ET1010的IO数据485从机数据

需求概述

本章节主要演示如何实现EG2000网关和ET2100节点实现组网通信以及采集多个ET2100数据汇总上传云端。如下可以实现采集多个ET2100扩展模块ET1010或者ET1020的IO数据，也可以采集多个ET2100下的485从机数据。

EG2000+ET2100组网|ET1010的IO数据485从机数据

设备间组网

1. 准备工作

EG2000参考连接网关教程，进入编程界面，进行LoRa通信的参数配置。

ET2100参考ET2100使用说明，进行LoRa参数配置。

2. 配置步骤

组网设备LoRa通信参数需相同，EG2000 网关与 ET2100 节点的射频参数和应用参数必须保持一致。以下为本示例需配置的相关参数：

射频参数：

空中频率：4800

发射功率：30

信道：23

RSSI：禁用

加密：H1 L1

应用参数：

模式：正常

网络ID：2

2.1. ET2100配置

ET2100默认是有默认射频参数和应用参数的，可以先使用配置软件读取出来，然后根据需求修改相关参数，操作如下：

注：多个ET2100组网配置一致。

2.2. EG2000配置

使用LoRa节点进行通信参数配置

3. 通信测试

可以通过互相发送数据看数据数据状态或者通过EG2000去采集ET2100下的设备数据来测试组网通信是否成功，这里以互发数据测试为例：

数据采集

1. 采集扩展IO数据

ET2100 采用 Modbus 协议，级联的 ET1020/1010 实际上相当于 ET2100 的 IO 口。有关寄存器的详细信息，请查看相关文档ET2100。EG2000 网关可以通过 Modbus 节点进行数据采集，以采集站地址为2的ET2100的IO数据（级联的一个ET1010（4DO/4DI）和一个ET1020（4AO/4AI））为例，配置如下：
