DNP3 Outstation Features & Functionality
The following DNP3 Outstation features support on CPE400/CPL410 and CPE115 controller:
Common Features:
1. Static Polling: Data can be assigned to a class and the master can poll by class (Class0, Class1, Class2 and
Class3). This allows high priority signals to be polled more frequently than lower priority signals.
2. Sequence of Events: Events between transmissions are captured and stored in the outstation until the
next poll. Supports a "sequence of events" history for Binary data (DI, DO and Counters Objects), Analog
data (AI, AO and AOV Objects). Supports SOE data transmission on all the 8 Channels for the points that
are configured with SOE option.
3. Status flags: Data can be appended with an indicator of the status (Quality) of the data.
4. Report by Exception (RBE): Minimizes network traffic by reporting only data that has changed. (DI, DO, AI,
AO, AOV and Counters).
5. Unsolicited Response From the Outstation: Remote devices can report field events without being polled
by the master station. A response message can be immediately sent to the master without waiting for the
next cyclic poll.
6. Time synchronization and a standard time format.
7. Control Operations: Select Before Operate, Direct Operate, Direct Operate-No Ack.
8. Control Relay Output Block (CROB) Operate command: PULSE_ON, PULSE_OFF, LATCH_ON, LATCH_OFF,
TRIP and CLOSE.
9. Analog Output Block (AOV) Operate command.
10. Analog input reporting Deadband.
11. Linear and Circular Event Buffer Configuration for storing the Sequence of events.
12. Configurable Data Link Layer confirmation (Never, Only for multi-frame messages, or Always).
13. Configurable Application Layer confirmation (Only when reporting event data or When reporting event
data or multi-fragment messages).
14. Timeout configuration: Data Link Layer Confirmation Response Time Out, Data Link Layer Receive
Response Time Out, Application Confirmation Time-Out Occurs.
15. Strict TCP/IP Address matching: Allows the TCP/IP connections from Master Stations that are configured
in DNP3 outstation.
16. Strict Lower: Level Address matching: Allows the LLA Address for Master Stations that are configured in
DNP3 outstation.
17. Support Point Push functionality which allows users to manually push the Event data into the protocol
stack database, or to override default options related to the configuration, or value of points.
18. Supports special variation: "44" in case of Analog Input Objects such as Object 30, 32, 34 and Analog
Output Objects 40 & 42.
19. Supports Per-Point and Template Configuration. This feature is not supported when CPE115 DNP3
Outstation is configured using SVC_REQ.
CPE400/CPL410 Specific Features:
1. HSB Event Synchronization: Events generated in the ACTIVE unit are synchronized to BACKUP Unit.
