Program Section Repetition - Siemens SINUMERIK 840DE Programming Manual

Caution
The following applies to every subprogram call: The subprogram call must always be
programmed in a separate NC block.

only when the program is called, i.e. on the first run. The parameters remain unchanged for
the remaining repetitions. If you want to change the parameters during program repetitions,
you must make the appropriate provision in the subprogram.
