At Design Time, there are two capabilities to be supported:
- Participant Metadata Definition. This capability allows external users and systems (such as SDC or DCAE-MOD) to define participants that can take part in a control loop and to define the metadata that can be used on and configured on a participant when it is taking part in in a control loop. The post condition of an execution of this capability is that a participant is defined in the Control Loop Design Time Catalogue together with sets of metadata that can be used with this participant in control loops.
- Control Loop Composition. This capability allows users and other systems to create a control loop type by connecting a chain of participants together from the participants that are available in the Control Loop Design Time Catalogue. In an execution of this capability, a user will define the control loop chain, define the connections between participants, will select the correct metadata sets for each participant, and will define the overall control loop metadata. The post condition for an execution of this capability is a Control Loop definition in TOSCA stored in the Control Loop Design Time Catalogue.
At Run Time, the following capabilities are to be supported:
- Participant Management. This capability allows participants to register and deregister with CLAMP. The post condition for an execution of this capability is that a participant is available for participation in a control loop.
- Control Loop Commissioning and Decomissioning. This capability allows version controlled Control Loops to be taken from the Control Loop Design Time Catalogue and be placed in the Control Loop Run Time Catalogue. It also allows configuration of parameters that apply to the Control Loop Type, that is parameters that will apply to all control loop instances. Further, it allows control loop types to be commissioned on participants. Data that applies to all instances of a control loop type on a participant is sent to a participant. The participant can then take whatever actions it need to do to support the control loop type in question. The post condition for an execution of this capability is that the Control Loop definition is in the Control Loop Run Time Catalogue and all participants in this control loop type are commissioned, that is they are prepared to run instances of this control loop type.
