Feedback Parameter
Issue 12 (2019-01-15)
If the connected power meter is of another model, set the parameters as follows.

Description
 Set this parameter to 1 when the power meter uploads the
primary value.

Set this parameter based on the actual transformer ratio
when the power meter uploads the secondary value.
Set this parameter based on the parameter name to be
reported.
Indicates the valid value range of signals carried by the
analog output loop. The current range is less than or equal to
the current range set in the AO specifications. Start Data
corresponds to End Data.
Indicates the valid value range of signals of Feedback
Parameter. Set the two parameters as required. An excessive
range results in low precision of the feedback while an
insufficient range results in the incompleteness of the
feedback.
Description
Set this parameter to Other.
Read holding register 03H and Read input register 04H
are supported. Set this parameter based on the vendor's
protocol.
Multiple read and Single read are supported.
Big endian and Little endian are supported. Set this
parameter based on the vendor's protocol.
Set this parameter based on whether the power meter needs to
report the data of the grid-tied point.

Set this parameter to 1 when the power meter uploads the
primary value.
 Set this parameter based on the actual transformer ratio
when the power meter uploads the secondary value.
Set this parameter based on the vendor's protocol.
NOTE
If the power meter can collect a certain signal, set Signal address to
the address of the corresponding register. If not, set Signal address to
65535.
Set this parameter based on the parameter name to be
reported.
