12.12 Freely definable tables
Fundamentals
In freely definable tables you can save and read any information
from the NC program. The Q parameter functions
FN 26
to
FN 28
are provided for this purpose.
You can change the format of freely definable tables, i.e. the
columns and their properties, by using the structure editor.
They enable you to make tables that are exactly tailored to your
application.
You can also toggle between a table view (standard setting) and
form view.
The names of tables and table columns must start with
a letter and must not contain an arithmetic operator
(e.g.,
+
). Due to SQL commands, these characters can
cause problems when inputting data or reading it out.
Creating a freely definable table
To call the file manager, press the
PGM MGT
key
Enter any desired file name with the .TAB extension and
confirm it with the
ENT
key
The control displays a pop-up window with permanently stored
table formats
Use the arrow key to select the desired table template,
e.g.
example.tab
and confirm it with the
ENT
key
The control opens a new table in the predefined format
To adapt the table to your requirements you have to edit the
table format
Further information: "Editing the table format", page 571
Refer to your machine manual.
Machine tool builders may define their own table
templates and save them in the control. When you
create a new table, the control opens a pop-up window
listing all available table templates.
You can also save your own table templates in the
control. To do so, create a new table, change the table
format and save the table in the
TNC:\system\proto
directory. Then your template will also be available in
the list box for table templates when you create a new
table.
