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).
You will find a detailed description of the channel types of Set01W_x and Par12D_x in the
section Data objects: Specific channel parameters (Page 210).
During configuration make sure that the two objects of every pair in the station access the
same address range in the CPU when mirroring back.
Mirroring back a value changed by local operator input
The mirror back mechanism is explained based on Bin08X_x.
1. A value sent by the master station is written to the CPU by the receive object of the
station.
2. Following this, the value is changed in the memory area of the CPU by local operator
input.
3. The modified value can be mirrored back to the master station with one of the two
following types of transmission:
● Static
Example: Bin08X_S without configured event class (basic settings of the object)
This corresponds to the DNP3 object group 10, variation 2.
The new value is transferred only when polled by the DNP3 master station.
