• You can click the , , or tab on the tertiary navigation menu to query EMI-related information.
• EMI performance data can be stored for a month and exported. When changing the name of the exported file, retain the extension .tar.gz. Otherwise, the file will be unavailable.

Devices from different vendors may support different protocol specifications. To normally obtain information from the connected EMI, correctly configure the protocol specifications over the SmartLogger WebUI based on the protocol specifications delivered by the vendor.

After the SmartLogger connects to the EMI, manually add the device. For details, see Connecting Devices. Device Type should be set to EMI.

Because of permission restriction, log in as Advanced User. Choose Monitoring > EMI and set EMI parameters.

Figure 7-22 EMI

• When the connected device model is in the EMI model drop-down list, set the parameters as follows.

  Parameter	Description
  EMI model	Set this parameter to the model of the corresponding EMI. Currently, the following models are supported: ABB VSN800-12, ABB VSN800-14, Gill MetPak Pro, Hukseflux SRx, Ingenieurbüro Si-RS485TC, Kipp&Zonen SMPx, Lufft WSx-UMB, Lufft WSx-UMB (external sensors), Meier-NT ADL-SR, Meteo control SR20-D2, Rainwise PVmet-150, Rainwise PVmet-200, Soluzione Solare SunMeter, JinZhou LiCheng, JinZhou YangGuang (PC-4), and HanDan (RYQ-3).
  Synchronize Environment Data	Retain the default value Disable. NOTE: If Enable is selected, wind speed and direction will be sent to the inverters in a PV plant with the tracking system.
  Master/Slave	When the SmartLogger connects to multiple EMIs, you can set one of them to master mode. The inverter performance data contains that of the EMI in master mode.

• If the connected EMI is a split-type one that supports the Modbus-RTU protocol, set the parameters as follows.

  Parameter	Description
  EMI model	Set this parameter to Sensor(ADAM).
  Synchronize Environment Data	Retain the default value Disable. NOTE: If Enable is selected, wind speed and direction will be sent to the inverters in a PV plant with the tracking system.
  Master/Slave	When the SmartLogger connects to multiple EMIs, you can set one of them to master mode. The inverter performance data is that of the EMI in master mode.
  Read function code	Read holding register 03H and Read input register 04H are supported. Set this parameter based on the vendor's protocol.
  Data reporting mode	Integer and Floating point are supported. Set this parameter based on the vendor's protocol.
  Word ordering	Big endian and Little endian are supported. Set this parameter based on the vendor's protocol.
  Read mode	Multiple read and Single read are supported.
  Start address	When Read mode is set to Multiple read, set the start address.
  End address	When Read mode is set to Multiple read, set the end address.
  Signal NOTE: Signal-related parameters include Signal Name, Signal address, Lower Thres., Upper Thres., Spec, Start (mV/mA), and End (mV/mA).	Set this parameter based on the vendor's protocol. NOTE: If the EMI can collect a certain signal, set Signal address to the address of the corresponding register. If not, set Signal address to 65535.

• If the connected EMI is of another model, set the parameters as follows.

  Parameter	Description
  EMI model	Set this parameter to Other.
  Synchronize Environment Data	Retain the default value Disable. NOTE: If Enable is selected, wind speed and direction will be sent to the inverters in a PV plant with the tracking system.
  Master/Slave	When the SmartLogger connects to multiple EMIs, you can set one of them to master mode. The inverter performance data contains that of the EMI in master mode.
  Read function code	Read holding register 03H and Read input register 04H are supported. Set this parameter based on the vendor's protocol.
  Data reporting mode	Integer and Floating point are supported. Set this parameter based on the vendor's protocol.
  Word ordering	Big endian and Little endian are supported. Set this parameter based on the vendor's protocol.
  Read mode	Multiple read and Single read are supported.
  Start address	When Read mode is set to Multiple read, set the start address.
  End address	When Read mode is set to Multiple read, set the end address.
  Signal NOTE: Signal-related parameters include Signal Name, Signal address, Gain, and Offset.	Set this parameter based on the vendor's protocol. NOTE: If the EMI can collect a certain signal, set Signal address to the address of the corresponding register. If not, set Signal address to 65535.
