We consider the capabilities of Control Loops at Design Time and Run Time.
At Design Time, two three capabilities are supported:
- Control Loop Element Definition Specification. This capability allows users to define Control Loop Element Types and the metadata that can be used on and configured on a Control Loop Element Type. Users also define the Participant Type that will run the Control Loop Element when it is taking part in in a control loop. The post condition of an execution of this capability is that metadata for a Control Loop Element Type is defined in the Control Loop Design Time Catalogue.
- Control Loop Element Definition Onboarding. This capability allows external users and systems (such as SDC or DCAE-MOD) to define the metadata that can be used on and configured on a Control Loop Element Type and to define the Participant Type that will run the Control Loop Element when it is taking part in in a control loop. The post condition of an execution of this capability is that metadata for a Control Loop Element Type is defined in the Control Loop Design Time Catalogue.
- Control Loop Type Definition. This capability allows users and other systems to create Control Loop Type definitions by specifying a set of Control Loop Element Definitions from those that are available in the Control Loop Design Time Catalogue. These Control Loop Elements will work together to form Control Loops. In an execution of this capability, a user specifies the metadata for the Control Loop and specifies the set of Control Loop Elements and their Participant Types. The user also selects the correct metadata sets for each participant in the Control Loop Type and defines the overall Control Loop Type metadata. The user also specifies the Common Property Types that apply to all instances of a control loop type and the Instance Specific Property Types that apply to individual instances of a Control Loop Type. The post condition for an execution of this capability is a Control Loop definition in TOSCA stored in the Control Loop Design Time Catalogue.
