the DNP3_Cmd01X_R object and sends the local value back to the master via the mirror
back channel.
You will find a detailed description of the channel types in the section Data objects: Specific
channel parameters (Page 206).
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.
● As event
Example: Bin08X_S with configured event class (basic settings of the object)
This corresponds to the DNP3 object group 11, variation 2.
For the transfer of the new value to the DNP3 master station, one of the two following
options can be set for the send trigger of the channel in the station:
– Send at change of"
Here, you define the deviation of the value in the memory area of the CPU at which
message transfer is triggered.
With this send trigger, all values are sent back to the master station that have either
been changed manually or overwritten by a new value from the master station.
– “Time trigger"
With this send trigger, you can trigger the transfer of a message according to the
following time-related criteria:
- Time of day
- Time scheme
– Trigger signal"
With this send trigger, for example, you can configure the signal resulting from manual
intervention as an input that then triggers transfer of the message.
