The different attributes for each parameter can be seen in
the section on factory settings. Since a parameter value
can only be transferred as a whole number, a conversion
factor must be used to transfer decimals.

Standard data types
Standard data types are int16, int32, uint8, uint16, and
uint32. They are stored as 4x registers (40001–4FFFF). The
parameters are read using function 03HEX "Read Holding
Registers. " Parameters are written using the function 6HEX
"Preset Single Register" for 1 register (16 bits), and the
function 10 HEX "Preset Multiple Registers" for 2 registers
(32 bits). Readable sizes range from 1 register (16 bits) up
to 10 registers (20 characters).
Non-standard data types
Non-standard data types are text strings and are stored as
4x registers (40001–4FFFF). The parameters are read using
function 03HEX "Read Holding Registers" and written using
function 10HEX "Preset Multiple Registers." Readable sizes
range from 1 register (2 characters) up to 10 registers (20
characters).
