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(DRB1-6)
• the DRP parameter Operation must be set Enabled
• the DRP must be trigged (binary or analog)
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 (DR), indications (IND) and event recorder function (ER).
Function block
The Indications function has no function block of it's own. It is included in the
DRPRDRE block and uses information from the BxRBDR block.
Input signals
The Indications function logs the same binary input signals as the Disturbance report
function.
