The registers are numbered in accordance with the Modbus
standard. These are "HOLDINGS REGISTER" on the range of reg‐
isters from 40001 to 49999.
Some software and Modbus controllers use an address from 0 to
65535.
Modbus register 40001 therefore corresponds to Modbus address
0, register 40002 corresponds to address 1 and so on and so forth.
