Bytes

Modbus does not know a byte or character data type (see

address space). Strings or byte arrays are mapped in "hold-

ing registers" (2 characters per register) and transmitted as

a "character stream", e.g. "Hello_World".

Words

Registers or words are transmitted according to speciﬁ cation

in "Big Endian" format, e.g. Read Holding Register 40101

of Slave 17.

Real

Modbus does not know any data types to represent ﬂ oat-

ing point numbers. On principle, any data structures may

be mapped on the 16Bit register ("cast"). The IEEE 754

standard is the most used standard to represent ﬂ oating

point numbers.

Bit

Exponent

Algebraic sign

The ﬁ rst register contains Bits 15 – 0 of the 32-bit number

(bit 0...15 of the mantissa).

The second register contains Bits 16 – 32 of the 32-bit number

(algebraic sign, exponent and Bit 16- 22 of the mantissa).

6.3 Mapping

Address space

The address space may be divided into 4 address spaces

according to the 4 types of data.
