DNP3 Configuration Parameters
1. Most Recent – When this event mode is configured, only the
latest event (i.e. static data value) is stored and reported to
DNP3 master.
2. SOE (Sequence of Events) – With this event mode configuration,
sequence of events will be stored and reported to DNP3 master
as historical data. SOE is a technique whereby the DNP3 module
will store events even if a master is not connected. SOE
collection will continue until such time as either the maximum
storage space for SOE storage has been exhausted, or the master
connects.
All the configured DNP3 Points can generate Events. The Events can be
either be instances of a single point change, or multiple changes of the
same point.
DNP3 Outstation supports following Class Masks:
1. CLASS MASK NONE – No Event data will be generated; all the
Point values can be polled through general
Interrogation/Integrity Poll.
2. CLASS MASK ONE – Events generated are categorized as Class-1
Events.
3. CLASS MASK TWO - Events generated are categorized as Class-2
Events.
4. CLASS MASK THREE - Events generated are categorized as Class-
3 Events.
All the Events can be classified under Class 0 or Class 1, 2 or 3. Events
from individual Classes can be polled different intervals as needed by
DNP3 Master.
DNP3 Outstation supports Per-Point Configuration where selected points
can have non-default Event Mode and Class Mask Type. This parameter
allows us to specify the number of points that requires non-default Event
Mode and Class Mask Type.
1. If this parameter is configured as 0, No points in the DNP3 object will
participate in Per-Point Configuration and have default configured
values of Event Mode and Class Mask type.
2. If it is configured as non-zero, then user will be provided with Per-
Point Object XX Tab where Users can choose Point Index for which
the Event Mode and Class Mask Type can be configured with other
than default value.
Note: Each DNP3 Object support a maximum of 512 Per-Point
Configurations.
For CPE115, this parameter is not applicable when configured using
SVC_REQ.
