a. For pallet entries (PAL), the values refer to the end of the kinematics chain (usually the
machine datum MP960.x). In NC programs the values refer to the pallet datum if a
PALPRES is active for the respective pallet.

Meaning
If—due to a tool change—an NC program must be stopped
during tool-oriented machining, the iTNC enters a code. This
code enables the iTNC to resume the machining process at the
position where it has been stopped.
Optional field (not used in standard format):
Location of pallet.
If the LOCATION column is used, an NC program can be run only
if this column contains the entry MA (= pallet for the machine)
for this pallet.
Optional field:
Lines containing any entry in this column will not be run.
If more than one program or pallet is to be run, the next
permitted line is used. Unlocked lines in a locked pallet are also
skipped.
Optional field:
Line number to be activated in the active pallet preset table.
Freely definable
Basically it does not make a difference whether a PRESET is called from a PAL
line or a PGM line. In both cases, the PRESET refers to the end of the
kinematics (usually table center point = machine datum). If an active pallet
preset table exists in addition, however, the two are added (preset from pallet
preset table for PAL + preset from preset table for PGM/PAL).
If a pallet preset is activated in a PAL line, any subsequent PRESET (from the
PGM line or not) is based on it.
