16.2.1 Standard Data Types
All data types described by standard IEC61131-3 are supported by »PLC Designer«. See
here the following
• BOOL
• Integer Data Types
• REAL / LREAL
• STRING
• WSTRING
• Time Data Types
Notice that there are also some norm-extending data types and that you can also
define types on your own (user defined data types).
bool
BOOL type variables may be given the values TRUE (1) and FALSE (0). 8 bits of memory
space will be reserved.
See also: BOOL constants (Operands)
Integer Data Types
See below a list of all available integer data types. Each of the different number types
covers a different range of values. The following range limitations apply to the integer
data types:
Type Lower limit Upper limit Memory space
BYTE 0 255 8 Bit
WORD 0 65535 16 Bit
DWORD 0 4294967295 32 Bit
LWORD 0 2

SINT -128 127 8 Bit
USINT 0 255 8 Bit
INT -32768 32767 16 Bit
UINT 0 65535 16 Bit
DINT -2147483648 2147483647 32 Bit

ULINT 0 2 64-1 64 Bit
As a result when larger types are converted to smaller types, information may be lost.
