7.15.3 Programming variables
In principle, variables or expressions can also be used in the input fields of the screen forms
instead of specific numeric values. In this way, programs can be created very flexibly.
Input of variables
Please note the following points when using variables:
● Values of variables and expressions are not checked since the values are not known at
the time of programming.
● Variables and expressions cannot be used in fields in which a text is expected (e.g. tool
name).
An exception is the "Engraving" function , in which you can assign the desired text in the
text field via a variable as "Variable text".
● Selection fields generally cannot be programmed with variables.
Examples
VAR_A
VAR_A+2*VAR_B
SIN(VAR_C)
7.15.4 Setting data for technological functions
