Data types
Main run variables can feature the following data types:
INT Integer for whole values with prefix signs
REAL Real for rational counting
BOOL Boolean TRUE and FALSE
CHAR ASCII character
STRING Character string with alpha-numerical characters
AXIS Axis addresses and spindles
Preprocessing variables can also feature the following data types:
FRAME Coordinate transformations
10.3.2 Implicit type conversion
Function
During value assignments and parameter transfers, variables of different data types are
assigned or transferred.
The implicit type conversion triggers an internal type conversion of values.
Possible type conversions

BOOL Yes Yes Yes – – – –
Explanations
* At type conversion from REAL to INT, fractional values that are >=0.5 are rounded
up, others are rounded down (cf. ROUND function).
An alarm is output if values are exceeded.
1)
Value <> 0 is equivalent to TRUE; value == 0 is equivalent to FALSE
