Data types

The following data types are available in the NC:
Data type Significance
INT Integer with sign
REAL Real number (LONG REAL to IEEE)
BOOL Truth value TRUE (1) and FALSE (0)
CHAR ASCII character
STRING Character string of a defined length
AXIS Axis/spindle identifier
FRAME Geometric parameters for static coordinate
transformation (translation, rotation, scaling,
mirroring)
Implicit data type conversions
The following data type conversions are possible and are performed implicitly during
assignments and parameter transfers:
REAL
INT
BOOL
x : Possible without restrictions
o: Data loss possible due to the range of values being overshot ⇒ alarm;
rounding: decimal place value ≥ 0.5 ⇒ round up, decimal place value < 0.5 ⇒ round down
&: value ≠ 0 ⇒ TRUE, value== 0 ⇒ FALSE
