The required JSON for the module twin desired properties is auto populated. Select the Modbus module, ModbusTCPModule, in the list and select the Module Twin Settings tab.

Review the deployment manifest and select Create.

The Routes are also automatically configured.

The module is automatically configured for your IoT Hub and appears in the list of IoT Edge Modules.

Search for Modbus and select the Modbus TCP Module by Microsoft.

Click the Add dropdown and select Marketplace Module.

In the IoT Edge Modules section, add the Modbus module: Go to IoT Edge and click on your IoT Edge device. This section walks through deploying Microsoft's sample Modbus module to your IoT Edge device. Those articles provide instructions on creating new modules and publishing container images to a registry. To create a container image, refer to Develop C# modules in Visual Studio or Develop modules in Visual Studio Code. Follow the guidance in that project to create your own container image.

If you want to create your own module and customize it for your environment, there is an open-source Azure IoT Edge Modbus module project on GitHub.

You can access the module from the Azure Marketplace, Modbus, or with the image URI, /azureiotedge/modbus:1.0. If you want to test the Modbus gateway functionality, Microsoft has a sample module that you can use.

A physical or simulated Modbus device that supports Modbus TCP.

The primary key connection string for the IoT Edge device.

For a walkthrough on how to set up one, see Deploy Azure IoT Edge on Windows or Linux. For more information about how to configure the module to support Modbus RTU, see the Azure IoT Edge Modbus module project on GitHub. This article assumes that you're using Modbus TCP protocol. This article covers how to create your own container image for a Modbus module (or you can use a prebuilt sample) and then deploy it to the IoT Edge device that will act as your gateway. The gateway device reads data from your Modbus devices, then communicates that data to the cloud using a supported protocol.

If you want to connect IoT devices that use Modbus TCP or RTU protocols to an Azure IoT hub, you can use an IoT Edge device as a gateway.
