The MODE input defines if the output signals from SINGLECMD:1 is off, steady or
pulsed signals. This is set in Parameter Setting Tool (PST) under:
Setting / General
Settings / Control / Commands / Single Command .
Event function
Event function is intended to send time-tagged events to the station level (for example,
operator workplace) over the station bus. The events are there presented in an event
list. The events can be created from both internal logical signals and binary input
channels. All the internal signals are 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 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:
Setting / General Setting / Monitoring / Event Function 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)
