- System Pre-Configuration. This capability allows participants to register and deregister with CLAMP. Participants explicitly register with CLAMP when they start. Control Loop Priming is performed on each participant once it registers. The post condition for an execution of this capability is that a participant becomes available (registration) or is no longer available (deregistration) for participation in a control loop. Participants explicitly register with CLAMPwhen they start.
- Control Loop Commissioning. This capability allows version controlled Control Loop Type definitions to be taken from the Control Loop Design Time Catalogue and be placed in the Control Loop Run Time Inventory. It also allows the values of Common Property Types that apply to all instances of a Control Loop Type to be set. Further, the Control Loop Type is primed on all concerned participants. The post condition for an execution of this capability is that the Control Loop Type definition is in the Control Loop Run Time Inventory and the Control Loop Type is primed on concerned participants.
- Control Loop Priming on Participants. A participant is primed to support a Control Loop Type. The definition of a control loop and the values of Common Property Types that apply 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. Control Loop Priming takes place at participant registration and at Control Loop Commissioning. The post condition for an execution of this capability is that all participants in this control loop type are commissioned, that is they are prepared to run instances of their Control Loop Element types.
- Control Loop Life Cycle Management. This capability allows a Control Loop Instance to be created. The Control Loop Type definition is read from the Control Loop Run Time Inventory and values are assigned to the Instance Specific Property Types defined for instances of the Control Loop Type in the same manner as the existing CLAMP client does. A Control Loop Instance that has been created but has not yet been instantiated on participants is in state UNINITIALIZED. In this state, the Instance Specific Property Type values can be revised and updated as often as the user requires. Once the user is happy with the property values, the Control Loop Instance is instantiated on participants and the Control Loop Elements for this Control Loop Instance are started by participants using the control loop metadata. Once the Control Loop Instance is instantiated on each participant, the Control Loop Instance is set as being in state PASSIVE in the Control Loop Run Time Inventory. The user can now order the participants to change the state of the Control Loop Instance to state RUNNING. Each participant begins accepting and processing control loop events and the Control Loop Instance is set to state RUNNING in the control loop inventory. The post condition for an execution of this capability is that the Control Loop instance is running on participants and is processing events.
- Control Loop Monitoring. This capability allows Control Loop Instances to be monitored. Users can check the status of Participants, Control Loop Instances, and Control Loop Elements. Participants report their overall status and the status of Control Loop Elements they are running periodically to CLAMP. Clamp aggregates these status reports into an aggregated Control Loop Instance status record, which is available for monitoring. The post condition for an execution of this capability is that Control Loop Instances are being monitored.
