Structuring NC programs
Definition and applications
The control enables you to comment NC programs in structuring
blocks. Structuring blocks are texts with up to 252 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 NC programs in a clear and comprehensible manner.
This function is particularly convenient if you want to change the
NC program later. Structuring blocks can be inserted into the
NC program at any point.
Structure blocks can also be displayed in a separate window, and be
edited or added to, as desired. Use the appropriate screen layout for
this.
The control manages the inserted structure items in a separate
file (extension: .SEC.DEP). This speeds navigation in the program
structure window.
The
P SECTS
screen layout can be selected in the
following operating modes:
Program run, single block
Program run, full sequence

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