4.4 Azure IoT OPC Proxy

The Azure IoT-Hub Proxy view allows to set up a connection between edgeGate and Microsoft Azure IoT Hub. For

doing so it is required that the Azure cloud is accessible from the device via the Internet.

Note

This description only applies to the edgeGate product!

Note

From the view of the description at the Microsoft: 5 Clicks to Digital Factory webpage edgeGate acts

as Field Gateway/Relay.

registration and unregistration as Microsoft Azure IoT Hub proxy device.

created based on the hostname and the current time, if this input field is empty. Note: This device-id should

be different from the device id of the MQTT connection to the Azure cloud (see embedded-linux-softing-

uagate-c.md).

Note

The device ID Azure Device-Id should be different from the device ID used for the MQTT

connection (see Embedded-linux-softing-uagate-c.md).

Azure IoT OPC Proxy
