Mirroring back
Mirroring back
The values of data points in DNP3 stations that are set by commands or setpoints by the
DNP3 master station can also be set by manual operator input in the station. This overwrites
the values set by the master station.
With the following object pairs, the current values in the station can be mirrored back to the
DNP3 master station:
●
Setpoint objects Set01W_S / Set01W_R (object groups 40/42)
Setpoints with mirror back functionality are sent by the master to a station using the
Set01W_S object. The station receives the data via the Set01W_R object.
The receive object (..._R) of the station mirrors the current or, if applicable, locally entered
value back to the master station using the channel type "LocalSetpointInput".
To receive the value mirrored back by the station, the send object (..._S) of the master
station has the channel type "ReturnedSetpoint".
– Set01W_R in the DNP3 station
Send channel of Set01W_R for the local setpoint: LocalSetpointInput
– Set01W_S in the DNP3 master station
Receive channel of Set01W_S for the mirrored back setpoint: ReturnedSetpoint
●
Parameter objects Par12D_S / Par12D_R (object groups 40/42)
Parameter settings with mirror back functionality are sent by the master to a station using
the Par12D_S object. The station receives the data via the Par12D_R object.
The receive object (..._R) of the station mirrors the current or, if applicable, locally entered
value back to the master station using the channel type "LocalParameterInput".
To receive the value mirrored back by the station, the send object (..._S) of the master
station has the channel type "ReturnedParameter".
– Par12D_R in the station
Send channel of Par12D_R for the local parameters: LocalParameterInput
– Par12D_S in the master station
Receive channel Par12D_S for the mirrored back parameters: ReturnedParameter
●
Message/binary value objects Bin08X_S / Bin08X_R (object groups 10/11)
Messages / binary values are sent by the master to a station using the Bin08X_S object
(object group 12). The station receives the data via the Bin08X_R object.
The mirrored back value can be sent to the master station by the station using the
Bin08X_S object (object group 10 or 11). The master station receives the mirrored back
value with the Bin08X_R object (object group 10 or 11).
●
Command object DNP3_Cmd01X_R (object group 12)
A command with Control Code is sent by the master (SCADA system) to the station with
a suitable command of the object group 12 / variation 1. The station receives the data via
