DHCP is set to Disable by default.
Ensure that the IP addresses for the SUN2000s and PC are different values in the same network
segment.
2. Set Modbus TCP to Client. Set NetEco IP address, NetEco port number, SSL
encryption, and Key password based on site requirements.
For operations with the SUN2000 APP, see the SUN2000 APP User Manual.
For operations with the NMS, see the iManager NetEco 1000S User Manual (iManager NetEco
1000S V100R002C20 and later).
Selecting a Communication Mode
The RS485 and PLC communication modes are mutually exclusive.
If the PLC communication mode is selected, do not connect the RS485 communications
cable. In addition, you need to set PLC communication to Enable on the SUN2000
APP.
The PLC communication mode is only applicable to medium-voltage grid connection
scenarios and non-low-voltage public grid connection scenarios (industrial environment).
If the RS485 communication mode is selected, do not connect the PLC CCO module to
the AC power cable. In addition, you are recommended to set PLC communication to
Disable on the SUN2000 APP.
PLC communication is set to Enable by default.
5.5.2 Connecting RS485 Communications Cables
Note
An RS485 communications cable can be connected in two ways:
Terminal block connection
You are recommended to use a DJYP2VP2-22 2x2x1 network cable or a
communications cable with a conductor cross-sectional area of 1 mm
2
and cable outer
diameter of 14–18 mm.
RJ45 network port connection
You are recommended to use a shielded RJ45 connector and a CAT 5E outdoor shielded
network cable with an outer diameter less than 9 mm and internal resistance not greater
than 1.5 ohms/10 m.
Select either connection mode during installation. Connecting to a terminal block is recommended.
