Function controlled by SetLEDn setting in Disturbance report function.
Indication list:
The possible indication signals are the same as the ones chosen for the disturbance report
function and disturbance recorder.
The indication function tracks 0 to 1 changes of binary signals during the recording period
of the collection window. This means that constant logic zero, constant logic one or state
changes from logic one to logic zero will not be visible in the list of indications. Signals
are not time tagged. In order to be recorded in the list of indications the:
• the signal must be connected to binary input BxRBDR function block
• the DRPRDRE parameter Operation must be set Enabled
• the DRPRDRE must be trigged (binary or analog)
• the input signal must change state from logical 0 to 1 during the recording time.
Indications are selected with the indication mask ( IndicationMask ) when setting the
binary inputs.
The name of the binary signal that appears in the Indication function is the user-defined
name assigned at configuration of the IED. The same name is used in disturbance recorder
function, indications and event recorder function.

14.6 Event recorder
14.6.1 Functionality
Quick, complete and reliable information about disturbances in the primary and/or in the
secondary system is vital, for example, time-tagged events logged during disturbances.
This information is used for different purposes in the short term (for example corrective
actions) and in the long term (for example functional analysis).
The event recorder logs all selected binary input signals connected to the Disturbance
recorder function. Each recording can contain up to 150 time-tagged events.
