For supported Modbus register (see Section 4, page 15). System Topology An SMA product with Modbus interface is connected with the SCADA system of the electric utility company or the grid operator via Ethernet. The Modbus interface also enables communication via the Modbus protocol. From the perspective of the Modbus protocol, an SMA product with Modbus interface constitutes a Modbus server that supports the SMA Modbus profile. -
