Data Types
There are different data types that you can use depending on the purpose of the application:
bit, integer, double-length integer, quadruple-length integer, real number, double-precision real
number, and address.

Conforms to IEEE754 standards.
The MP3000-series Machine Controller does not have separate registers for each data type. As
shown in the following figure, the same address will access the same register even if the data
type is different. For example, MB00001003, a bit address, and the MW0000100, an integer
Important
address, have different data types, but they both access the same register, MW0000100.
