time tagged in the main processing module, while the binary input channels are time tagged
directly on each I/O module. The events are produced according to the set of event masks. The
event masks are treated commonly for both the LON and SPA channels. 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.
Two special signals for event registration purposes are available in the IED, Terminal Restarted
(0E50) and Event buffer overflow (0E51).
The input parameters can be set individually from the Parameter Setting Tool (PST) under: Main
Menu/Settings / IED Settings / Monitoring / Event Function or via parameter Setting Tool (PST)
as follows:
• No events
• 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, event system itself make the reporting decision, (reporting criteria for integers
has no semantic, prefer to be set by the user)
The Status and event codes for the Event functions are found in table
858.
