4.7 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 way.
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.
To display the program structure window /
change the active window:
U U U U To display the program structure window, select the
screen display PGM+SECTS.
U U U U To change the active window, press the "Change
window" soft key.
To insert a structuring block in the (left) program
window
U U U U Select the block after which the structuring block is to be inserted.
U U U U Press the INSERT STRUCTURE soft key or the * key
on the ASCII keyboard.
U U U U Enter the structuring text with the alphabetic
keyboard.
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.
