RS485 parameters
RS485-1
to
RS485-6
respectively correspond to communications ports
COM1
–
COM6
, and the
baud rate is 9600 bit/s by default. The baud rates for devices connected to the same RS485 port must
be the same.
Set the protocol supported by the RS485 port based on either the protocol supported by the
connected device or the status of the device in the network. When the SmartLogger serves as a slave
node to interconnect with a third-party device over Modbus-RTU, set
Protocol
to
Modbus-Slave
.
When the connected inverter performs rapid power grid scheduling using both PLC and RS485, set
Protocol
to
Modbus-Control
.
Protocol
,
Parity
, and
Stop Bit
must be set to the same values for all devices connected to the same
RS485 port.
1 ≤ start address ≤ end address ≤ 247. The address segments for each RS485 port from
RS485-1
to
RS485-6
can overlap.
Set the address range as required. A larger address range requires a longer searching time. The start
and end addresses have no impact on the devices that have been connected.

connection data, set
Meter feedback output
to
Disable
.
If the power meter model is displayed in the drop-down list box of
Intelligent Power
Meter Type
, select it, as shown in
When the connected power meter model is not any one of the three above, select
