In the field **Select Gateway**, choose the gateway you want to connect to. Only see gateways that are online, and linked to projects to which you have access, will be available. Choose **modbus.tcp** in **Select Slave Definition**. After this, you can select the IP address to which the DSE controller is connected in **Select Slave**. Finally, click on the **Activate** button to create a tunnel connection to the selected gateway.

Click on **File** and then on **Settings**. From here, go to the **Communication** tab. For **Communication type**, choose **TCP-IP**. When you use Calculus Digger, you must always enter **127.0.0.1** at **IP address of the device** and **1** at **Device modbus ID**. Under **Advanced settings** you can set the time-out values a bit higher because the traffic is no longer done locally, but via the internet and a 4G internet connection. Click **OK** and **Start communication with the device** (F5).
