Parameter
Description
Voltage change ratio
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.
Current change ratio
Feedback Parameter
Set this parameter based on the parameter name to be
reported.
Start Current (mA)
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
.
End Current (mA)
Start 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.
End Data
If the connected power meter is of another model, set the parameters as follows.
Parameter
Description
Intelligent Power Meter
Type
Set this parameter to
Other
.
Read function code
Read holding register 03H
and
Read input register 04H
are supported. Set this parameter based on the vendor's
protocol.
Read mode
Multiple read
and
Single read
are supported.
Word ordering
Big endian
and
Little endian
are supported. Set this
parameter based on the vendor's protocol.
Meter feedback output
Set this parameter based on whether the power meter needs to
report the data of the grid-tied point.
Voltage change ratio
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.
Current change ratio

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
.
Feedback Parameter
Set this parameter based on the parameter name to be
reported.
