●
shows the communication mode for multiple SUN2000s.
If multiple SUN2000s are used, connect all the SUN2000s in daisy chain mode
over an RS485 communications cable.

NO TE
● The RS485 communication distance between the SUN2000 at the end of the daisy
chain and the SmartLogger cannot exceed 1000 meters.
● If multiple SUN2000s need to communicate with one another and are connected
to a PC over the SmartLogger1000, a maximum of three daisy chains can be
configured.
● If multiple SUN2000s need to communicate with one another and are connected
to a PC over the SmartLogger2000, a maximum of six daisy chains can be
configured.
● To ensure the system response speed, it is recommended that the number of
devices on each daisy chain be less than 30.
MBUS (PLC) Communication
The MBUS (PLC) communication board loads communication signals onto power
cables for transmission.
NO TE
The built-in MBUS (PLC) module in the SUN2000 does not need to be connected with
additional cables.
Selecting a Communication Mode
The RS485 and MBUS (PLC) communication modes are mutually exclusive.
