Nesting rules
The following features regulate the interaction between NC commands
IPTRLOCK
and
IPTRUNLOCK
with
nesting and end of subroutine:
1.
IPTRLOCK
is activated implicitly at the end of the subroutine in which
IPTRUNLOCK
is called.
2.
IPTRLOCK
in an untraceable section has no effect.
3. If subprogram1 calls subprogram2 in a search-suppressed area, subprogram2 remains search-suppressed.
IPTRUNLOCK
in particular has no effect in subroutine 2.
Examples of nesting with two program levels
Nesting of search-suppressed program sections in 2 program levels.
An interruption in a search-suppressed program section of the above program always returns
N10030 G4 F1
block.
With implicit IPTRUNLOCK
Nesting of search-suppressed program sections in two program levels with implicit IPTRUNLOCK. The implicit
IPTRUNLOCK
in subprogram 1 ends the search-suppressed area.
