PROC ... PREPRO
Significance
PREPRO:
Read subprogram with preparation and subprogram call
The cycle directories are processed in the same order both for subprograms preprocessed
with parameters during power up and during subprogram call.
1. _N_CUS_DIR user cycles
2. _N_CMA_DIR manufacturer cycles
3. _N_CST_DIR standard cycles
In the case of NC programs sharing the same name but having different characteristics, the
first PROC operation found is activated and the other PROC operation is overlooked without an
alarm message.
