Data Types Used for System-defined Variables for Motion Control
System-defined variables for motion control use both basic data types and derivative data types.
 Basic Data Types

Data type
Size
Range of values

Boolean
BOOL
2*
TRUE or FALSE
TRUE or FALSE
Integer
UINT
2
0 to +65,535
UDINT

0 to +4,294,967,295
Binary expression: "2#" is added to the
front of the number
Octal expression: "8#" is added to the
front of the number
Decimal expression: "10#" is added to the
front of the number
Hexadecimal expression: "16#" is added
to the front of the number
If you do not add any notation to the
beginning of a number, that number is
treated as a decimal number.
Example:
Binary Notation
2#1111_1111
2#1110_0000
