Unsigned double precision integer (UINT32)

Large numbers are put into unsigned 32-bit integers. By default, they are set up so that the
first word (register) is the most significant word (MSW) and the second word (register) is the
least significant word (LSW). For example, if R41,442 is read as a UINT32, the 32 bits would
look like this:
The two registers are read as a 32-bit integer.
The most significant word (MSW) and least significant word (LSW) can be reversed to
accommodate some Modbus drivers. See Word order (R40,062) (Page 329) for details.
The position of the decimal place is dependent on the register. For more details, see the
description of the register.
