Chapter 6 Micro870 Controller Distributed Network Protocol
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 10000 (see
), regardless of the Event data type. In 2080-L70E-24Q
x
BN 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 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.
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 and 16-bit Analog Input Object
Data is configured in the DNP3 mapping table.
