RCU database digital points list
Name/states/source Status/events/restart/qualifiers
State: Set on start-up and periodically every 24 hours thereafter. Cleared when
time updated by SCADA protocol.
Events: No events generated for this point.
On restart: Volatile - state set on restart.
Data qualifiers: Override.
State: Set when communications are ok to the Fusesaver. Cleared when
communications are not ok to the Fusesaver.
Events: Events generated by change of state above.
On restart: Volatile - state clear on restart.
Data qualifiers: Override, online, restart.
State: Set when communications module battery has failed a battery test or is
nearing exhaustion. Cleared when the communications module battery is ok.
Events: Events generated by change of state above.
On restart: Volatile - state clear on restart.
Data qualifiers: Override, online, restart, communications lost.
State: Set when Fusesaver line current is on. Cleared when Fusesaver current is
off. This status data comes from the Fusesaver live-data stream.
Events: Events generated by Fusesaver line current on event. Cleared event
generated by line current off event, protection trip event, manual trip event or
three-phase lockout event. These events come from the Fusesaver event record.
On restart: Volatile - state clear on restart.
Data qualifiers: Override, online, restart, communications lost.
State: Set when permanent fault event has been generated by the Fusesaver.
Cleared by protection flag reset timer or by operator control.
Events: Set event generated when a permanent fault event has been generated
by the Fusesaver. Cleared event generated when state is cleared as above. Note
that only the ongoing event is significant, the cleared event should be discarded
by the SCADA system.
On restart: Volatile - state clear on restart.
Data qualifiers: Override, online, communications lost.
State: Set when cleared fault event has been generated by the Fusesaver.
Cleared by protection flag reset timer or by operator control.
Events: Set event generated when a cleared fault event has been generated by
the Fusesaver. Cleared event generated when state is cleared as above. Note
that only the ongoing event is significant, the cleared event should be discarded
by the SCADA system.
On restart: Volatile - state clear on restart.
Data qualifiers: Override, online, communications lost.
State: Set when detected fault event has been generated by the Fusesaver.
Cleared by protection flag reset timer or by operator control.
Events: Set event generated when a detected fault event has been generated by
the Fusesaver. Cleared event generated when state is cleared as above. Note
that only the ongoing event is significant, the cleared event should be discarded
by the SCADA system.
On restart: Volatile - state clear on restart.
Data qualifiers: Override, online, communications lost.
