Power Meter Without Feedback of Grid Connection Data
If a power meter connected in the PV plant does not need to provide feedback of the grid
connection data, set Meter feedback output to Disable.

 RS485-0 corresponds to communications ports AC1 and AC2 of the PLC in the SmartLogger, and
the baud rate is 115,200 bit/s by default. 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 SUN2000 performs rapid power grid scheduling using both PLC and RS485,
set Protocol to Modbus-Control.
 Protocol and Parity 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 RS485-0 to

RS485-6 can overlap.
If the SmartLogger communicates with the SUN2000 over an embedded PLC module, set an address
segment for RS485-0. Otherwise, the SmartLogger will fail to access the corresponding SUN2000.
If the SmartLogger does not communicate with the SUN2000 over an embedded PLC module, you
do not have to set an address segment for RS485-0.
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.
When the model of the connected power meter is UMG604, PD510, or PZ96L, select
the model in the drop-down list box of Intelligent Power Meter Type.
