N100 IPTRLOCK() ; is ineffective

An interruption in the search-suppressed program section of the above program always
returns block "N10030 G4 F1" in SPARPI.
An interruption at N100 then returns N100 again.
Automatic interrupt pointer
In certain applications it can be useful to automatically define a prespecified type of coupling
as a search-suppressed area. The automatic interrupt pointer function is activated with
machine data
MD 22680 $MC_AUTO_IPTR_LOCK.
• Bit 0 = 1: Electronic gear with EGON
• Bit 1 = 1: Axial master value coupling with LEADON
This program section begins with the last executable block before activation and ends with
deactivation.
The automatic interrupt pointer is not active for couplings, which are activated and
deactivated in synchronized actions.
Example: To declare axial master value coupling as search-suppressed:
N100 G0 X100 ;
N200 EGON(Y, "NOC", X, 1, 1) ; Search-suppressed program section
starts
N300 LEADON(A, B, 1) ;
... ;
N400 EGOFS(Y) ;
... ;
N500 LEADOF(A, B) ; Search-suppressed program section
ends
N600 G0 X200 ;
A program abort within the search-suppressed program section (N200 - N500) always
supplies N100 to the interrupt pointer.
Caution
Using an overlap of the "programmable interrupt pointer" and
"automatic interrupt pointer" via machine data, the NC selects the largest possible search-
suppressed area.
A program may need a coupling for almost all of the runtime. In this case, the automatic
interrupt pointer would always point to the start of the program and the SERUPRO function
would in fact be useless.
