3.9.3 Event reporting mode: When responding with event data and more than one event has occurred for
a data point, an Outstation may include all events or only the most recent event. Only the most recent
event is typically reported for Analog Inputs. When reporting “only most recent”, the analog value reported
in the response may be the value at the time of the original event or it may be the value at the time of the
response.
● A: Only most recent
(value at time of event)
Most Recent – Event
Time
● B: Only most recent
(value at time of
response)
● C: All events
