12. Access the desired addresses at the Modbus sheet in Radzio (Fig 11) as described in the Modbus document
(Fig 12).
If you only see zeros or bad values, check the Frame counter (Fig 11) to be sure that you receive “Valid
responses”.
If not, the settings may be wrong.

For example, you can read from base address 1840 (AC input L1)
AC input power value (U32 so address 4 will be MSB and address 5 LSB) = 106 [VA]
Input voltage (U16) at address 6 = 2321 [0.1 V] = 232.1 [V]
Input current (U16) at address 7 = 4 [0.1 A] = 0.4 [A]
Input frequency (U16) at address 8 = 499 [0.1 HZ] = 49.9 [Hz]
