Figure 3:
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 3.
