DCPConsumer Interface and Argument Types
15.2 DCPConsumer
15.2.1 The DCPConsumer interface allows the equipment to provide DCP consumers with data collection results,
operational performance warnings, and DCP deactivation notifications. All DCP consumers must implement this
interface.
15.2.2 The notifications defined for the DCPConsumer interface are Fire-and-Forget messages. No replies from
consumers are specified. The equipment is not required to take action on any protocol-level replies or errors
received from consumers when sending these notifications, unless otherwise required by an implementation
specification. The equipment is not required to retry or buffer notifications if it determines that such notifications
are not being successfully delivered to a consumer. The equipment shall not deactivate any consumer’s DCPs if it
detects an error in the delivery of these notifications.
15.2.3 DCPConsumer Operations
Table 77 DCPConsumer Operation Definition
Operation Description Type Requestor/Sender Responder/
Receiver
NewData Communicates data collection results from an active
DCP to the consumer that activated the DCP.
FF Equipment Consumer
PerformanceWarning Warns the consumer when the equipment has detected
degradation of its performance (see Section 13).

Operation Description Type Requestor/Sender Responder/
Receiver
PerformanceRestored Notifies the consumer when the equipment has
detected a return to normal performance conditions
(see Section 13 ).
FF Equipment Consumer
DCPDeactivation Notifies the consumer when the equipment is
deactivating a DCP previously activated by that
consumer.
FF Equipment Consumer
DCPHibernation Notifies the consumer when the equipment is placing
one or more persistent DCPs in a hibernation state as
part of a shutdown sequence.
FF Equipment Consumer
15.2.4 NewData — The equipment shall send this notification whenever data from an active DCP is available for
the consumer that activated the DCP.

15.2.5 PerformanceWarning — The equipment shall send this notification to all consumers with
ManageOnlyAuthoredDCPs privilege or higher whenever operational performance has degraded below a supplier-
specified threshold (see Section 13.1.7).

15.2.6.1.1 PerformanceStatus — This class, shown in Figure 33, describes the current status of the equipment’s
ability to perform its intended function. It includes the time the performance status was last evaluated, whether or
not the performance is below the equipment-defined threshold, and a description of the current status. See Section
13 for further details.
