ABB Relion 670 series - Function block; Input signals; Technical data

events in chronological order. The list can contain up to 1000 events from both internal
logic signals and binary input channels. If the list is full, the oldest event is overwritten
when a new event arrives.
The list can be configured to show oldest or newest events first with a setting on the
local HMI.
The sequential of events function runs continuously, in contrast to the event recorder
function, which is only active during a disturbance, and each event record is an integral
part of its associated DR.
The name of the binary signal that appears in the event recording is the user-defined
name assigned when the IED is configured. The same name is used in the disturbance
recorder function (DR), indications (IND) and the event recorder function (ER).
The sequential of events is stored and managed separate from the disturbance report
information(ER, DR, IND, TVR and FL).
15.8.3 Function block
The Sequential of events has no function block of it’s own.It is included in the
DRPRDRE block and uses information from the BxRBDR block.
15.8.4 Input signals
The Sequential of events logs the same binary input signals as configured for the
Disturbance report function.
