4.6 Structuring Programs

Definition and applications

This TNC function enables you to comment part programs in
structuring blocks. Structuring blocks are short texts with up to 37
characters and are used as comments or headlines for the subsequent
program lines.

With the aid of appropriate structuring blocks, you can organize long
and complex programs in a clear and comprehensible manner.

This function is particularly convenient if you want to change the
program later. Structuring blocks can be inserted into the part program
at any point. They can also be displayed in a separate window, and
edited or added to, as desired.

The inserted structure items are managed by the TNC in a separate file
(extension: .SEC.DEP). This speeds navigation in the program
structure window.

Displaying the program structure window /
Changing the active window

To display the program structure window, select the

screen display PROGRAM+SECTS.

To change the active window, press the “Change

window” soft key.

Inserting a structuring block in the (left) program
window

Select the block after which the structuring block is to be inserted.

Press the SPEC FCT key to select the special

functions.

Press the INSERT SECTION soft key.

Enter the structuring text with the alphabetic

keyboard (see “Screen keypad” on page 81)

If necessary, change the structure depth with the soft

key.

Selecting blocks in the program structure
window

If you are scrolling through the program structure window block by
block, the TNC at the same time automatically moves the
corresponding NC blocks in the program window. This way you can
quickly skip large program sections.
