4.6.3 Connecting the SmartLogger to a Split EMI

Connecting to an EMI over a COM Port
The EMI used in Europe and Southeast Asia is composed of sensors, whose signals need to be
converted into RS485 signals (Modbus-RTU) over an extra analog-to-digital converter before
the sensors are connected to the SmartLogger.
The analog-to-digital converter should provide an RS485 port and support the standard
Modbus-RTU protocol. This section describes the connection between the SmartLogger and a
split EMI through the ADAM4117 that functions as an analog-to-digital converter.
The SmartLogger provides six RS485 communications ports. For the port descriptions, see

and Comm.protocal to Modbus-RTU.
 After adding an EMI, set its parameters. For details, see
Setting Running Parameters. The EMI model is Jingzhou Yangguang (PC-4), Handan (RYQ-3),
Kipp&Zonen SMPx or Lufft WSx-UMB.

If the SmartLogger needs to be connected to an EMI and multiple SUN2000s, connect the EMI at
the end of the daisy chain, and verify that the port connected to the EMI has a unique
communications address. For the daisy chain connection, see
Connecting Multiple SUN2000s.
