DNP3 10K Event Logging
Up to 10,000 events can be logged. To configure the number of events, change the Unsolicited

be used for controlling into the Trigger Event and Disable Change Events field.
The following example shows how to control the event generation condition by using the
Deadband for Analog Input Objects.
