Event masks
Event mask for each input can be set individually from Parameter Setting Tool (PST)
under: 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, the EVENT function makes the reporting decision (reporting criteria
for integers has no semantic, prefer to be set by the user)
Single indication
Directly connected binary IO signal via binary input function block (SMBI) is always
reported on change, no changed detection is done in the EVENT function block. Other
Boolean signals, for example a start or a trip signal from a protection function is event
masked in the EVENT function block.
Double indications
Double indications can only be reported via switch-control (SCSWI) functions. Event
reporting is based on the information coming from SCSWI functions, so no change
detection is done in the EVENT function block.
Directly connected binary IO signal via binary input function block (SMBI) is not
possible to handle as double indication. Double indications can only be reported for
the first 8 inputs on an EVENT function block.
• 00 generates an intermediate event with the read status 0
• 01 generates an open event with the read status 1
• 10 generates a close event with the read status 2
• 11 generates an undefined event with the read status 3
