11 Data types in PLC Designer

11.1 Standard data types

11.1.1 Data types

You can use standard data types and user-defined data types when programming.

Each identifier is assigned to a data type which dictates how much memory space will

be reserved and what type of values it stores.

11.1.2 BOOL

BOOL type variables may be given the values TRUE and FALSE. 8 bits of memory space

will be reserved.

11.1.3 Integer Data Types

BYTE, WORD, DWORD, SINT, USINT, INT, UINT, DINT, and UDINT are all 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

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

UDINT: 0 4294967295 32 Bit

As a result when larger types are converted to smaller types, information may be lost.
