5.5.3. Indicator object monitoring
The indicator object monitoring function takes care of the status monitoring of circuit breakers and
disconnectors. The function's sole purpose is indication and does not therefore have any control
functionality. To control circuit breakers and/or disconnectors, please use the Object control and
monitoring function. The monitoring is based on the statuses of the con gured relay's digital inputs.
The number of monitored indicators in a relay depends on the available inputs and outputs. The status
monitoring of one monitored object usually requires two (2) digital inputs. Alternatively, object status
monitoring can be performed with a single digital input: the input's active state and its zero state
(switched to 1 with a NOT gate in the Logic editor). The selection of the object type is done in Mimic
editor.
The outputs of the function are the monitored indicator statuses (Open and Close). The setting
parameters are static inputs for the function, which can only be changed by the use in the function's
setup phase.
The inputs of the function are the binary status indications. The function generates general time
stamped ON/OFF events to the common event buffer from each of the following signals: OPEN,
CLOSE, BAD and INTERMEDIATE event signals. The time stamp resolution is 1 ms.
Settings
Function uses available hardware and software digital signal statuses. These input signals are also
setting parameters for the function.

Displays the status of the indicator object. Intermediate status is displayed when
neither of the status conditions (open or close) are active. Bad status is displayed
when both of the status conditions (open and close) are active.

Signal
Range
Description
IndicatorX
Open
input
("Ind.X
Open
Status In")
Digital input or
other logical
signal selected
by the user
(SWx)
A link to a physical digital input. The monitored indicator's OPEN status. "1" refers to
the active "Open" state of the monitored indicator. Position indication of digital inputs and
protection stage signals can be done by using IEC 61850 signals, GOOSE signals or logical
signals.
IndicatorX
Close
input
("Ind.X
Close
Status In")
Digital input or
other logical
signal selected
by the user
(SWx)
A link to a physical digital input. The monitored indicator's CLOSE status. "1" refers to
the active "Close" state of the monitored indicator. Position indication of digital inputs and
protection stage signals can be done by using IEC 61850 signals, GOOSE signals or logical
signals.
Events
The indicator object monitoring function (abbreviated "CIN" in event block names) generates events
from the status changes in the monitored signals, including the continuous status indications. The user
can select the status ON or OFF for messages in the main event buffer.
