A.3 Modbus registers
All registers denoted with a bullet (•) in the read-only column are read-only registers and should be read with the function
“read input registers.” All other registers can be read and written with “read holding registers” or “write multiple registers.”
NOTE: The modbus register address map supported by Aurora H2O is shown in Table 7 below.
