6.13.20 Pallet Management (as of NC software 280 472-01)
Configuring a pallet
table The pallet table is a “freely definable table”:
7 7 7 7 Define the prototype in the directory PLC:\PROTO with the file name
extension .P.
7 7 7 7 Create the prototype.
(See “Freely Definable Tables” on page 6 – 310).
If you have more than one prototype with the file name extension *.P, a menu
for format selection will appear when you create a pallet table. Your PLC
program must be adapted to the various formats.
The COPY SAMPLE FILES soft key copies two prototypes into the directory
PLC:\PROTO.
Both prototypes are offered when you create a new pallet table. If you do not
want this to happen, delete a prototype from the PLC:\PROTO directory. Then
the existing prototype is used automatically.
n
Prototyp.P = standard prototype (PAL/PGM, NAME, DATUM, X, Y, Z)
n
Proto_to.P = prototype for tool-oriented machining
Field names The following types of fields are used in the pallet table:
n
Mandatory fields: Values must be entered.
n
Optional fields: Values can be entered. They have a fixed, predefined
meaning for the NC.
n
Freely definable fields: You can display additional fields. The names and
meaning are defined as desired. The entries are for information, or you can
interrogate and change them through the PLC.
Name Type of
machining Meaning
PAL/PGM Workpiece-
oriented/tool-
oriented Mandatory field:
Definition of the entry, PAL = pallet, PGM = NC program
FIX = fixture (only tool-oriented)
W-STATE Tool-oriented Optional field:
Machining status, BLANK, ENDED, INCOMPLETE
METHOD Tool-oriented Mandatory field:
Type of machining
TO = tool-oriented, WPO = workpiece-oriented,
CTO = continued tool-oriented (for multiple entries)
NAME Workpiece-
oriented/tool-
oriented Mandatory field:
Name of the pallet or the NC program.
NC program names without paths are searched for in the
directory with the pallet file.
Permit only decimal numbers, so that you can interrogate the
pallet’s name in the change macro with FN18.
