An untraceable section can be detected in the parts program with
Automatic interrupt pointer
The automatic interrupt pointer automatically defines a previously defined coupling type as
untraceable. The machine data for

● axial leading value coupling with

interrupt pointer activated with automatic interrupt pointers overlap, the largest possible
untraceable section will be generated.
