When the SmartModule is connected to the SmartLogger, the device name of the
SmartModule is Module(M1), and the corresponding port is M1.COM.
RS485
Protocol, Baud rate, Parity, and Stop Bit must be set to the same values for the
devices connected to the same COM port.
Parameter Description
Protocol Set this parameter based on the protocol type of the
connected device.
The value can be Modbus, IEC103, DL/T645,
Modbus-Slave, or Modbus-Control.
NOTE
● 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 solar inverter performs rapid power
grid scheduling using both MBUS and RS485, set Protocol
to Modbus-Control.
Baud rate Set this parameter based on the baud rate of the
connected device.
The value can be 1200, 2400, 4800, 9600, 19200, or
115200.
Parity Set this parameter based on the parity mode of the
connected device.
The value can be None, Odd parity, or Even parity.
Stop Bit Set this parameter based on the stop bit of the
connected device.
The value can be 1 or 2.
Start address 1 ≤ Start address ≤ Communication address of the
connected device ≤ End address ≤ 247
The address segments of COM ports can overlap.
NOTE
The start and end addresses have no impact on the devices
that have been connected.
End address
Night Comm. Settings
If device information query is not required at night, enable Night silent.
