Systems
Systems define the scope for a set of Things, e.g., a plant site. A System determines which Configuration entities are allowed within it, affecting which entities can be used by Things in that System.

Thing Types

Multiple Thing Types can be allowed in a System. A System can also exist without any Thing Types being allowed.

Features
Select which Features should be allowed in this System.
Multiple Features can be allowed in a System. A System can also exist without any Features being allowed.
Note that available Features are pre-configured and cannot be changed by the User.
Profiles
A Profile can inherit other Profiles, which leads to inheritance of Profile Attributes and Metrics.
Profile composition can be nested: if a Profile inherits another Profile which inherits a third Profile, the first Profile inherits Attributes and Metrics from both the second and third Profiles.
Select which Available Profiles should be allowed in this System and click the transfer button:
Check the Assigned Profiles for newly assigned Profiles. If an assigned Profile has inherited Profiles, they are shown, but grayed out.
Available Profiles and Assigned Profiles are searchable by Profile Name:
Note that Thing Types referenced in the desired Profiles must also be allowed. For example, if a Profile is based on Thing Type Asset, the Thing Type Asset must be allowed in the System.
See the Profiles section for information on how to create or edit Profiles.
Relation Types
Select which Relation Types should be allowed in this System.
Multiple Relation Types can be allowed in a System. A System can also exist without any Relation Types being allowed.
Note that Thing Types referenced in the desired Relation Types must also be allowed. For example, if a Relation Type connects Asset to Asset, the Thing Type Asset must be allowed in the System.
See the Relation Types section for information on how to create or edit Relation Types.
Data Providers
Select which Data Providers should be allowed in this System.
Multiple Data Providers can be allowed in a System. A System can also exist without any Data Providers being allowed.
Note that to allow Data Providers, the Feature Type Metric must be allowed in the System.
See the Data Providers section for information on how to create or edit Data Providers.
Identifiers
Identifiers define how Things of a specific Thing Type can be identified within the System.
Note that the desired Thing Type must be allowed in the System before adding Identifiers.
Select the Thing Type to which an Identifier should be added, then click the Add button to add a new Identifier.
Provide:
- Name: is required and must be unique.
