Components in dashed-line boxes are optional.
When the smart array controller communicates with the inverter over PLC, log in to the embedded
WebUI of the SmartLogger2000, choose Monitoring > MBUS (PLC) > Networking Settings, and set
Networking to Enable (default value). When the smart array controller communicates with the inverter
only over RS485, set Networking to Disable. For details, see the SmartLogger2000 User Manual. (The
WebUI screenshots for SmartLogger V200R002C20SPC119 are used as an example.)
RS485 communication mode
All models of smart array controllers support the RS485 communication mode.
−
− The SmartLogger connects to the box-type transformer, power meter, inverter, PID
module, PLC CCO module, and other devices that support RS485 communication
over COM ports.
The figure displays only major components and cables and is for reference only.
PLC communication mode
− If a double-column transformer is used, use the smart array controller that supports
the access of one PLC route.
