Changing A Cycle Call - Siemens SINUMERIK 840D sl Operating Manual

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)
