15.3.1 General description of data formats
It is important to distinguish between primitive data types (integers, floats, text) and composite data types
(integer points, float points, lists) as well as the format of the corresponding data type (ASCII-dec, binary,
ASCII-2 decimal places).
15.3.1.1 Integer
This data type is a whole number value and can also be negative.
Example: 234
Format Text representation Transferred value (process interface)
ASCII hex
„EA"
\45 \41
ASCII dec
„234"
\32 \33 \34
Binary cannot be represented \00 \00 \00 \EA
15.3.1.2 Float
This data type is a floating value and can also be negative.
Example: 10.02
Format Text representation Transferred value (process interface)
ASCII (2 decimal places)
„10.02"
\31 \30 \2E \30 \32
ASCII (Exponent) "+1.002E+01" \2B \31 \30 \30 \32 \45 \2B \30 \30 \31
Decimal
„10"
\31 \30
Binary (Little Endian) cannot be
represented \EC \51 \20 \41
Binary (Big Endian) cannot be
represented \41 \20 \51 \EC
15.3.1.3 Text
This data type can contain both printable and non-printable characters.
Example: „MHD"
Format Text representation Transferred value (process interface)
ASCII
„MHD"
\4D \48 \44
