The cloud connector contains an ID that is unique to the station. This is known in Sentience terminology as the "System Guid" (Globally Unique IDentifier). Registration by the Niagara Cloud Device Registration web service assigns this ID to the system. The System Guid is tied to the System ID that can be found in the cloud connector's ConnectorImpl property as well as the Public/Private Key Pair that is stored securely in the Niagara Certificate Manager User Key Store. It is important to maintain all of these together. Removing one eliminates the ability of the connector to establish its identity with the Sentience identity provider, and thereby prevents the station from communicating with the cloud. The Alias used for the key in the User Key Store is the station's name, whereas the Subject is the System ID of the connector.

The System ID is established by combining the station name with the host ID of the platform, which generates a unique string to register with the Sentience identity provider.
