What are the forwarding protocols supported by the Data Logger?
Protocol Type Description
ModbusRTU/ModbusTCP
The Data Logger sends the collected data of devices
(such as inverter, combiner box, Meteo Station) to the
background. The background allocates forwarding
addresses to these devices, thereby accessing and
obtaining the data of the devices.
IEC104
1. Add or search devices on the Web interface (such as
inverter, combiner box, Meteo Station).
2. Export the IEC104 point table on System > Transfer
Configuration > IEC104 page. The point table shows
measuring point information of devices.
FTP
The Data Logger transfers the data of the collected
equipment (such as inverter, PV combiner box, Meteo
Station, etc.) to the remote monitoring system through the
FTP protocol.
MQTT
The Data Logger transfers the data collected from devices
(such as inverters, PV combiner box, Meteo Station,
etc.) to the remote monitoring system through the MQTT
protocol.
