HEIDENHAIN ITNC 530 User Manual page 158

If the entries TO or CTO for all workpieces within a group contain the
status ENDED, the next lines in the pallet file are run.
In mid-program startup, only one tool-oriented machining
operation is possible. Subsequent pieces are machined
according to the method entered.
The value entered in the CTID field is stored for a
maximum of 2 weeks. Within this time the machining
process can be continued at the stored location. After this
time the value is deleted, in order to prevent large
amounts of unnecessary data on the hard disk.
The operating mode can be changed after executing a
group of entries with TO or CTO.
The following functions are not permitted:
Switching the traverse range
PLC datum shift
M118
Leaving the pallet file
