All events according to the event mask are stored in a buffer, which contains up to 1000
events. If new events appear before the oldest event in the buffer is read, the oldest event is
overwritten and an overflow alarm appears.
Events are produced according to set event masks. The event masks are treated commonly for
both the LON and SPA communication. An
channel. These settings are available:
NoEvents
•
OnSet
•
OnReset
•
OnChange
•
AutoDetect
•
It is possible to define which part of the EVENT function generates the events. This can be
performed individually for communication types
each communication type these settings are available:
Off
•
Channel 1-8
•
Channel 9-16
•
Channel 1-16
•
For LON communication, events are normally sent to station level at change. It is also possible
to set a time for cyclic sending of the events individually for each input channel.
To protect the SA system from signals with a high change rate that can easily saturate the
EVENT function or the communication subsystems behind it, a quota limiter is implemented. If
an input creates events at a rate that completely consume the granted quota then further
events from the channel will be blocked. This block will be removed when the input calms down
and the accumulated quota reach 66% of the maximum burst quota. The maximum burst
quota per input channel is 45 events per second.

Setting guidelines

The input parameters for the Event function (EVENT) can be set individually via the local HMI
(Main Menu/Settings / IED Settings / Monitoring / Event Function) or via the Parameter
Setting Tool (PST).

EventMask (Ch_1 - 16)

7.2.1
The inputs can be set individually as:
NoEvents
•
OnSet , at pick-up of the signal
•
OnReset , at drop-out of the signal
•
OnChange , at both pick-up and drop-out of the signal
•
AutoDetect , the EVENT function makes the reporting decision (reporting criteria for
•
integers have no semantic, prefer to be set by the user)
