8.3.5 Sequence of Events (SOE)
SOE is the timestamped status data. SOE allows to review latest events and changes for device’s
state changes in chronological order. Newest events are shown at the top of the list. WCC Lite will
timestamp the status data with a time resolution of one millisecond.
Initially, all breakers, protection contacts digital status input points in the WCCLite; events captured
from IEDs shall be configured as SOE points. It’s possible to assign any digital status input data
point in the WCCLite as SOE point with Excel template during configuration.
Each time a device changes state, the WCClite will save it with timetag in internal storage. WCC
Lite will maintain a SOE buffer within the configured history size limitations.
Events are recorded only for devices that have
Event history size
field set. When
log size exceeds its limit, oldest records are deleted.
