4.5.4 Connecting Multiple SUN2000s

The SmartLogger can connect to multiple SUN2000s through a daisy chain or AC power
cables.
Daisy Chain Connection
In the daisy chain connection mode, the RS485OUT of one SUN2000 is connected to the
RS485IN port of the next SUN2000, and the first SUN2000 is connected to the SmartLogger
as described in
Issue 04 (2018-04-10)
Component
MCB
 If the SmartLogger communicates with the SUN2000 through PLC, no RS485 communications
cable needs to be connected between them.

After connecting cables to the AC ports, log in to the embedded WebUI and enable the PLC function
in the SmartLogger. For details, see
describes how to configure PLC parameters for the SmartLogger.
 The port used for PLC networking is RS485-0. The recommended Baud Rate for the port is 115200
bps, which can provide optimal communications performance.
