Parameter
Description
Master/Slave
When the SmartLogger connects to multiple EMIs, set one of
them to master mode. The solar inverter performance data
displayed is the data of the EMI in master mode.

If the connected EMI is a split EMI that supports Modbus-RTU, set parameters as
follows.
Parameter
Description
EMI model
Set this parameter to Sensor(ADAM).
Synchronize Environment
Data
You are advised to retain the default value Disable.
NOTE
When this parameter is set to Enable, the SmartLogger transmits the
wind speed and direction data to the solar inverter in a PV plant with
the tracking system.
Master/Slave
When the SmartLogger connects to multiple EMIs, set one of
them to master mode. The solar inverter performance data
displayed is the data of the EMI in master mode.
Read function code
Set this parameter to Read holding register 03H or Read
holding register 04H based on the protocol adopted by the
vendor.
Data reporting mode
Set this parameter to Integer or Floating point based on the
protocol adopted by the vendor.
Word ordering
Set this parameter to Big endian or Little endian based on
the protocol adopted by the vendor.
Read mode
The value can be Multiple read or Single read.
Start address
If Read mode is set to Multiple read, set the start address for
reading.
End address
If Read mode is set to Multiple read, set the end address for
reading.
Signal parameters
NOTE
Signal parameters include
Signal Name, Signal
address, Lower Thres.,
Upper Thres., Spec, Start
(mV/mA), End (mV/mA),
and Unit.
Set these parameters based on the vendor protocol.
NOTE
If the EMI can collect a signal, set Signal address for the signal to the
corresponding register address. If the EMI cannot collect a signal, set
Signal address for the signal to 65535.

If the connected EMI is of another model, set parameters as follows.
Parameter
Description
EMI model
Set this parameter to Other.
