12.10 Freely definable tables

Fundamentals

In freely definable tables you can save and read any information
from the NC program. The Q parameter functions D26 to D28 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.

The control opens a new table in the predefined format

Further information:
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.
