The MODE input defines if the output signals from SINGLECMD:1 is off, steady or
setable pulse length signals. This is set in Parameter Setting Tool (PST) under:
Main
Menu/Settings / IED Settings / Control / Commands / Single Command or via
Parameter Setting Tool (PST).
Event function EVENT
The Event function (EVENT) sends time-tagged events to the station level (for
example, operator workplace) over the station bus. On the station level, events are
presented in an event list. 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.
Events are produced according to a set of event masks. These masks are treated
commonly for both 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).
Input parameters can be set individually from the Parameter Setting Tool (PST) under:
Main Menu/Settings / IED Settings / Monitoring / Event Function or via the
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, the EVENT function makes the reporting decision (reporting criteria
for integers has no semantic, prefer to be set by the user)
For double indications, only the fist eight inputs, 1–8, must be used. Inputs 9–16 can
be used for other types of events in the same EVENT block.
Status and event codes for the EVENT function are found in Table 745 .
