Iot Hub 模块 "Modbus" 看起来健康且参数化良好，但未收到数据

Question

我正在将“Janitza UMG96RM-E”设备连接到 Windows 笔记本电脑，我在笔记本电脑上使用 Hyper-V 来使用 Linux cmds。我将笔记本电脑注册为边缘设备并将 Modbus 添加到模块集中。我阅读了 Janitza 文档（起始地址，位的 nbre ...）并且我在模块双胞胎文件中添加了正确的 IP 地址...一切看起来都很健康，除了我没有从 Modbus 模块接收任何数据...我不是能弄清楚哪里出了问题吗？这是 edgeHub 模块的一些日志。

以下是我从 Janitza 文档中用来配置模块孪生的信息： Modbus address list

Answer 1

你检查过模块的日志了吗？使用 iotedge list 检查模块的名称。

sudo iotedge list
sudo iotedge logs Modbus

您需要指定从 modbus 模块到 edgeHub 的 $upstream 通道的 route，以便将数据路由到与部署清单中的模块名称相匹配的 Azure IoT 中心。看起来是正确的，但 doublechek 不会有什么坏处。

要查看通过 IoT 中心的数据，您可以使用 Azure IoT explorer。

Answer 2

我发现问题出在我正在读取的寄存器 start-address 上。在我的例子中，我在开头添加了 4（Holding Register），在结尾添加了 +1。示例：如果在从站设备的文档中我可以从地址 19000 读取电源：在 Modbus 模块双胞胎中我将地址指定为 419001！我希望这对以后的人有所帮助。

Iot Hub 模块 "Modbus" 看起来健康且参数化良好，但未收到数据
