3.1.2 SW1 – Modbus Address

Use unique addresses: assign a unique Modbus slave address to each Modbus Slave device on the net-

work. Although Modbus allows for Modbus slave addresses from 1 to 247, you can still only connect 32 unit

loads (including the PV Plant PC).

The following table specifies the MODBUS addresses.
