Event Reporting
This section covers how to generate DNP3 events from DNP3 Data Objects and
how to report the generated events by polled response or unsolicited response.
Generate Events
The controller has a separate buffer area that you can use to log DNP3 events
internally.
The maximum number of the Events that can be logged is 6013 or 10000 (see
DNP3 10K Event Logging on page 250 ), regardless of the Event data type. With
Series B and Series C controllers, a Data-Set event can consume multiple
numbers of the event buffers.
If the number of the generated events reaches this value, the controller sets
IIN2.3 [EVENT_BUFFER_OVERFLOW]. Further events are not logged until
the logged events are reported to DNP3 Master and the buffer is available.
The elements CS0:67 or CS2:67 in the Communication status file show how
many events are logged to the event buffer. The logged events are not removed
until they are reported to DNP3 Master successfully. Logged event can also be
cleared when one of the following events occur:
• New OS firmware upgrade
• New user program download.
Figure 74 shows how to generate events for a Binary Input Object and a 16-bit
Analog Input Object. In the DNP3 Slave configuration, Binary Input Object
Data File Number is configured to 10 and its Configuration File Number is
